An anti-dust device for the dust removal equipment
- Shenzhen Chuangzhilian Technology Development Co., Ltd. -
Dust removal equipment failure or damage to the dust bag, resulting in increased dust concentration, resulting in excessive emissions or scrapped production equipment, and even cause dust explosions, these are the headache for the production enterprises. With the increasingly tightening of environmental protection management and the increasing emphasis on safe production, how to effectively prevent these hazards caused by dust has become a concern for everyone.
......
Fortunately, the dust content/concentration analyzer and dust content/concentration transmitter developed and produced by Shenzhen ChuangZhiLian Technology Development Co., Ltd. (hereinafter referred to as Shenzhen ChuangZhiLian) can analyze the change of dust concentration at the first time, and Alerts anomalies and helps companies respond in a timely and effective manner, effectively reducing dust problems.
Dust removal equipment needs a monitoring line of defense
"For the company's dust removal effect, it is currently more concerned about the concentration monitoring at the final discharge. In fact, monitoring will be carried out at the outlet of the dust removal equipment, and the effect will be better," said Ni Zhigang, sales manager of Shenzhen Chuangzhilian. The reporter learned that the monitoring of the company's dust emissions, the current environmental protection department is mainly located in the company's chimney to set up the monitoring point at the end, to detect whether the concentration of dust in the exhaust emissions outside the standard. Dust device outlet monitoring and how to measure? What is better?
In fact, Ni Zhigang's experience comes from his practice in the steel industry. Originally, almost every steel company was equipped with a blast furnace gas residual pressure turbine power generation unit (hereinafter abbreviated as TRT), which mainly uses the pressure energy and heat energy of blast furnace smelting by-products, blast furnace top gas, to generate electricity. This set of equipment is called the "printing machine" of the iron and steel enterprises, and the economic benefits are very high. Of course, its cost is not cheap, and the cost of the entire installation is more than 10 million yuan.
This device has a deadly "enemy" that is dust. Because in the high-speed operation of the TRT device, the fine particles will have a huge lethality. Once the dust concentration exceeds the limit, it will last for three months and long for half a year. The TRT device will be seriously damaged and the maintenance cost will often be several million. yuan. At present, iron and steel enterprises are basically equipped with bag dust removal equipment, to a great extent to eliminate the emergence of this problem. However, the equipment is also faulty and the bag will be damaged. Once the dust enters the TRT device, the consequences can be imagined. In order to prevent this from happening, a dust content/concentration analyzer was born.
“This kind of instrument was originally mainly imported from the United States and installed at the outlet of the dust removal equipment. Once the dust exceeds safety standards, the instrument will immediately report an alarm,†Ni Zhigang said. In order to protect the expensive TRT devices, each steel company will install This analyzer. This kind of instrument is actually very simple, that is, inserting a probe into the net gas pipeline of the dust removal equipment. Through the detection and analysis of the probe, the dust concentration value can be transmitted to the display and the computer terminal equipment, and the staff is clear at a glance.
“Compared to the terminal detection of the terminal discharge, the analyzer can find problems earlier and is more targeted. Once the dust removal equipment fails, it can be found and repaired in time.†Ni Zhigang mentioned that the dust concentration analyzer can accurately find The curve of dust concentration changes helps the staff to find out the cause of the accident. “From the curves, we can see the concentration changes at different times, so as to determine whether it is a mechanical failure or a broken bag, etc.
"Our company was established in 2009, initially mainly acting for such equipment, and has a clear understanding of its application and effectiveness." Ni Zhigang said that after this product was used in China, it received many praises from users and it was also The company laid a preliminary foundation for its early development.
PA-level monitoring technology leading domestic counterparts
"The domestic market is particularly special. Users are more concerned about the price of the product." Ni Zhigang said that although the United States products are easy to use, but the price is relatively expensive, so it is difficult to promote it. “Especially some domestic companies have begun to get involved in this industry, the quality of products has been mixed, and the agency of American companies has also been blooming. Market competition is becoming more and more intense and new ways must be found.â€
Is it always acting as an American agent? Why can't you produce similar high quality products yourself? After many years of market exploration and reflection, Shenzhen ChuangZhiLian led by Ni Zhigang resolutely invested a lot of money, and at the same time hired experts from the domestic dust analysis instrument industry and began to develop their own products.
"On the basis of learning from American products, experts in the United Nations have developed a dust content/concentration analyzer after about three years, and their performance is not inferior to that of American products, which has an advantage in price," said Ni Zhigang. The minimum measurement range of the device can reach 0.1 PA. "What is the concept? In this field, there are only about three companies in the world that can achieve this standard. Shenzhen ChuangZhiLian obtains an invention patent and a number of utility model patents. The domestic industry is blank."
PA is the current unit, 1PA = 0.000001 microamperes. In everyday life, we are more accustomed to using Ampere to calculate the intensity of the current, and 1 Ampere = 1000 mA, 1 mA = 1000 uA (uA) This comparison can be found that the unit of PA is very small. “The friction between objects will generate static electricity, dust is no exception, but the electrostatic current is proportional to the quality of the object itself, the static electricity entrained by the fine dust itself is actually very weak, ordinary equipment and instruments can not be found at all Static electricity, which requires precise equipment.†Ni Zhigang said that this analyzer is through the probe induction charged dust, thus detecting the content of dust in the air.
The reporter learned that most of the analyzers on the market today can only reach the milliamp level. In contrast, the set of analyzers developed by Shenzhen Zhichuanglian can detect the fine dust that can't be detected by other peers. The accuracy is higher and the application effect is even better.
"After a long period of time, baghouse dust removal equipment will produce clogging. At this time, there will be a backflushing process to shake off the dust that clogs the bag gap. At this time, the dust concentration will have a peak, which is the 'reverse blowing peak'. “Ni Zhigang said that when the bag is in perfect condition, the spike time is very short; if it is aging, it will last a long time; if it breaks, the spike will continue. “On our equipment, this curve is very obvious.†In the event of persistent peak data, it is necessary to check the equipment.†The reporter saw on the monitor that the longer the bag is used, the longer the peak value does last longer. The graph produced by the analytical instrument can be used for the performance of the dust bag. Accurately grasp, "Many devices on the market simply do not capture spikes, and there is no major change in data when it is blown back."
"These are the analyzers that we bought before. They were scrapped in two months. They are too lazy to demolition. However, Shenzhen ChuangZhiLian is a more reliable product. It has been measured very accurately for more than two years and it is also cheap." Shaoguan Steel The production manager of the company mentioned that after the installation of Shenzhen Zhichuanglian's analyzer, the dust collector was damaged and the bag was immediately damaged. It was able to recover a lot of losses for the company.
Li Gong of a steel plant in Guangxi also sent information to Ni Zhigang specifically saying, “Thank you for your products. It greatly reduces our labor intensity and can also reduce the cost of sacks for the boss.†Because there is no problem with the equipment after installing the analytical instrument, Analytical instruments can make scientific and accurate judgments, and then conduct targeted maintenance, saving the company a lot of manpower and material resources.
A good helper for the environmental protection industry
"The key reason why we can play a role is that the quality of equipment is excellent and the accuracy is high." Ni Zhigang disassembles the instruments on his hands. "Most parts are imported from abroad. Of course, these core technologies of induction and monitoring and analysis are ours. The independent research and development is also the core competitiveness of the equipment."
“Dust content/concentration analyzer quality is not lower than the dust meter imported from the United States, but the price is only half of the price of imported products in the United States. In order to meet the market demand, we have developed a more practical, more affordable dust content/concentration change. The transmitter is actually a condensed version of the dust content/concentration analyzer.†In Ni Zhigang’s company, the reporter compared the two, and the latter had less display meters. "In fact, the data can be displayed on a computer. This effect is not significant. The main difference is in the level of detection." Ni Zhigang said that the latter's detection standard is 5.0PA, the accuracy is not as high as the former, but for most companies This standard is enough to meet the demand, and the price is only about 1/5 of the former, and it is highly recognized by customers.
In terms of use, the two systems share the same characteristics and are simple. "No calibration is required, and meets the requirements of 'plug and play', as long as a mouth is opened at the outlet of the dust collector or bag filter flue gas duct, the probe is installed, the cable is connected to the control unit, and it can work "Ni Zhigang pointed out that the device's probe does not require air purging, and it is wear- and corrosion-resistant. It can basically guarantee that it will not be replaced in six years. The operating cost of the instrument is mainly the use of electricity, resulting in a relatively low cost, and it really is once and for all.
At present, with increasing environmental management requirements, dust removal, desulfurization, and denitrification facilities have become the standard for many industrial enterprises. These facilities range from a few hundred thousand to many millions and even tens of millions. The normal operation of these facilities is An important safeguard for protecting the environment. The reporter learned that dust removal is a very important part of these processes, because dust can cause some devices to clog or malfunction, and ultimately the effectiveness of treatment is greatly reduced. Installing a small analyzer on the dust removal device can solve this problem.
In addition, once enterprises exceed their standards, they need to pay a huge environmental protection cost. If an analyzer can be installed at the outlet of the dust collector, an early warning will be issued when the equipment has exceeded the discharge limit. This will not only save the company's losses but also contribute to environmental protection.
“As long as there are factories, such as bag filters, filter cartridge dust collectors and cyclone dust collectors, or dry dust collectors, they can all use our company’s dust instruments.†According to Ni Zhigang, in environmental dust removal equipment, basically With the addition of a dust meter, and based on the accuracy and price advantages of the equipment, the dust meter will be a very good accessory.
"The 'mind-heartedness' is our consistent business philosophy. Our dust instruments are cost-effective products. We will not reduce the quality of our dust instruments in order to cater to the market's low-cost needs, as long as they are dust instruments sold by our company. Our company will track and serve in the end." Ni Zhigang said, "From the point of view of the steel industry's many years of operation, this equipment has played a good effect, but also for the company to save costs, we also believe that it must be able to put in the environmental protection industry Splendor."
