Dust collector bag factory goes green
Environmental protection issues have been the focus of the National People's Congress and the National People's Congress in recent years, especially the problem of air pollution, and environmental protection stocks will also appear before and after the two sessions. Desulfurization and denitrification and industrial dust removal have become important means of air treatment and are being accelerated. Among them, the increasing market demand for desulfurization and denitrification has come to an end, and industrial dust removal is undergoing a transition from electric dust removal to bag dust removal. Whether it is from the perspective of market prospects or performance, it is more worthy of attention.
There is still a lot of room for improvement in the future of bag dust removal. From the perspective of the power industry alone, the domestic bag-type dust collector currently accounts for only about 10% of the industrial dust collector market, which is much lower than the level of foreign developed countries. For example, Australia's bag-type dust collection accounts for about 90% of the entire market, and Japan and the United States are also between 60% -80%. At present, the scale of China's bag-type dust removal market is about 10 billion. If the national emission standards continue to increase, and there is no major breakthrough in electric dust removal technology, the use of bag-type dust removal equipment will increase by one percentage point, and the market size will increase. In particular, the filter bag is a consumable, and it is usually replaced in 2-3 years.
Our prices are not lower than those of imported products, and our gross profit margin is steadily increasing. From the perspective of current capacity utilization and forward-looking perspectives such as market demand, the existing capacity is definitely not enough in the future, and it is expected that the capacity utilization rate will increase significantly this year. This year we are ready to start technological transformation. According to China Industrial Textile Industry Association, China's "Eleventh Five-Year Plan" puts forward higher demand for environmental protection. Water, gas, sound, and slag will all use more filter materials, and the filter material industry has a promising market prospect. Among them, in the field of soot control, bag-type dust removal has high dust removal efficiency, will not cause secondary pollution, and is convenient for the recovery of dry materials. It is more and more widely used at home and abroad, accounting for 80% of the dust removal equipment used. According to statistics, the total output value of the bag-type dust removal industry in 2005 was 6.5 billion yuan, a year-on-year increase of 21%. Despite the rapid growth rate, the national industrial demand continues to grow. In 2005, China's filter material output was about 40 million square meters, of which chemical fiber filter material was 30 million square meters, and glass fiber filter material was 10 million square meters. The output value reached 1.56 billion yuan, an increase of 31% over the previous year.
The iron and steel industry is one of the main sources of air pollution. China ’s steel output has exceeded 300 million tons. A total of 560 dry process cement production lines in China ’s new and old lines need to use high-temperature fiber filter bag dust removal equipment. In addition, there are living, medical, Bag-type dust removal equipment is also required for waste incineration including waste disposal.
Bag-type dust removal equipment is a dry dust filter device. After the filter material is used for a period of time, due to the effects of sieve filtering, collision, retention, diffusion, static electricity, etc., a layer of dust accumulates on the surface area of the filter bag.This layer of dust is called the primary layer.In the subsequent movement process, the primary layer becomes The main filter layer of the filter material, depending on the role of the primary layer, the filter material with a larger mesh can also obtain a higher filtration efficiency. With the accumulation of dust on the surface of the filter material, the efficiency and resistance of the dust collector increase accordingly.When the pressure difference between the two sides of the filter material is large, some fine dust particles that have been attached to the filter material will be squeezed over. Reduce the efficiency of the dust collector. In addition, the excessive resistance of the dust collector will significantly reduce the air volume of the dust collector system. Therefore, after the resistance of the dust collector reaches a certain value, it should be cleaned in time. The primary layer must not be destroyed during cleaning to avoid a drop in efficiency.
