At present, in addition to individual samplers, domestic particulate monitoring equipment relies on foreign products or foreign patents, which to a certain extent has formed a monopolistic situation for foreign equipment manufacturers. From the point of view of procurement of PM2.5 monitoring equipment throughout the country, from the analysis of technical requirements and location distribution, foreign manufacturers have great advantages. According to the survey conducted by reporters, foreign manufacturers have basically occupied more than 60% of the market share this year. At this stage, domestic manufacturers will mainly be in a follow-up position.
In response, Chai Fahe, deputy dean of the Chinese Academy of Environmental Sciences, said that foreign equipment has been dumped to the domestic market. If all (or most) foreign equipment is used, it will face certain risks. Over-reliance on imported equipment and equipment has adversely affected the formation of a controlled monitoring system with independent intellectual property rights in China. Over-reliance on foreign instruments will lead to a cold domestic equipment market, seriously restricting the development of local instruments, and will continue to be hampered by foreign equipment manufacturers in future equipment maintenance, parts replacement, and personnel training.
In the face of powerful international competitors, domestic manufacturers also need to strengthen their own R&D capabilities and cooperate with research institutes to conduct product R&D, upgrades, assessments, and inspections. They also need the support of the state and the government.
Brief introduction and editing of dust remover
Bag Filter [1] is a dry dust filter. After a period of use of filter material, due to the effect of sieve filtration, collision, retention, diffusion, static electricity and so on, the surface area of the filter bag is gathered in a layer of dust. This layer of dust is called the initial layer. In the course of the movement, the primary layer becomes the main filter layer of the filter material, and the larger filter material of the net hole can also get higher filtration depending on the effect of the initial layer. Efficiency. With the accumulation of dust on the surface of the filter material, the efficiency and resistance of the Dust Collector all increase correspondingly. When the pressure difference on both sides of the filter material is very large, some fine particles that have been attached to the filter material will be squeezed past to reduce the efficiency of the dust collector. In addition, the high resistance of the dust collector will reduce the air volume of the dust removal system significantly. Therefore, when the resistance of the dust collector reaches a certain value, the ash should be cleaned in time. When cleaning, the primary layer should not be destroyed, so that the efficiency will be reduced.
