Let's take a look at the explanation of dust removal equipment manufacturers !

China's electrostatic precipitator technology has matured, and its main technical level has entered the international advanced ranks.

1. Industry technology level and characteristics

The technical level and characteristics of this industry are mainly in the following aspects:

(1) Dust suppression by bio-membrane is included in the "Compilation of Advanced Technologies for Air Pollution Prevention" issued by the Ministry of Science and Technology and the Ministry of Environmental Protection

Bio-nano-membrane dust suppression technology, bio-nano-membrane is a double-ionization layer with nano-layer spacing, which can maximize the ductility of water molecules and has strong charge adsorption; spraying the bio-nano film on the surface of the material can Attract and agglomerate small particles of dust, aggregate them into large particles, and increase their weight to settle.

(2) Cloud and dust suppression is included in the "Compilation of Advanced Technologies for Air Pollution Control" issued by the Ministry of Science and Technology and the Ministry of Environmental Protection

Cloud mist suppression technology is through high-pressure ion atomization and ultrasonic atomization, which can produce ultra-fine dry mist of 1μm ~ 100μm; ultra-fine dry mist particles are dense, which fully increases the contact area with dust particles. Agglomerates to form agglomerates. The agglomerates become larger and heavier until they finally settle down naturally to achieve the purpose of eliminating dust.

(3) Wet dust collection is included in the "Compilation of Advanced Technologies for Air Pollution Prevention" issued by the Ministry of Science and Technology and the Ministry of Environmental Protection

Wet dust collection technology absorbs dust-adhered air through pressure drop, and removes dust under the dual effects of centrifugal force and the mixing of water and dust gas; key design such as unique impeller can provide higher dust removal efficiency.

(4) The electrostatic precipitator technology is already in the mature application stage, but the emission concentration is difficult to meet the requirements of the new control standard

China's electrostatic precipitator technology has matured, and its main technical level has entered the international advanced ranks.

Electrostatic dedusting technology has mature applications in high-temperature flue gas dedusting applications such as thermal power plants. Due to the limitation of the dust removal mechanism, it is difficult to improve the dust removal efficiency of the electrostatic dust removal technology, and the newly built electrostatic dust removal system can generally control its emission concentration at about 100mg / m3. At the same time, the dust removal efficiency is greatly affected by the change of the specific resistance of the soot. In actual operation, the uncertainty of the fuel used causes the working condition flue gas parameters to deviate from the design value, resulting in the soot emission concentration often being much higher than the designed emission control value. As the country ’s requirements for smoke pollution control continue to increase and the requirements for fine dust emissions become increasingly stringent, electrostatic precipitator technology is facing severe challenges.

(5) Bag-type dust removal technology is in the rapid development stage

Compared with electrostatic dedusting technology, bag dust removal technology started late. Through the introduction of foreign technology and digestion and absorption, China's bag-type dust collector technology has made great progress. Various bag-type dust collector technologies have become increasingly advanced, complete and complete. Filter material technology, dust cleaning technology, and accessories have gradually formed an industrial scale. The performance of some bag dust removal equipment has reached the international advanced level. After the dust-containing exhaust gas filtered by the bag type dust removal, the dust emission concentration can reach 5mg / m3, and the investment, operation and maintenance costs have gradually decreased, and the life of the filter bag has been continuously extended. With the continuous improvement of China's requirements for smoke pollution control, bag dust removal technology has been more and more widely used, and it is in a rapid development stage.

(6) Electric bag modification and electric bag composite technology are emerging

With the country's increasing requirements for industrial flue gas pollution control, electrostatic precipitator technology is facing severe challenges. Some enterprises that originally used electrostatic precipitator equipment have to transform the electrostatic precipitator equipment into bag-type dust collector equipment because they cannot meet the emission requirements. This method is referred to as "electric bag modification". At the same time, considering that most of China's existing high-temperature industrial flue gas dust removal uses electrostatic precipitator equipment, the existing up-front investment is relatively large. "Dust removal" technology transforms the rear end of the original electrostatic dust removal equipment into a bag type dust collector, and changes the electrostatic dust removal into an "electric bag type dust removal".

2. Industry-specific business model

Bag type dust collector is the core equipment in the dust removal system. The system design and configuration are professional and the customer's requirements are highly personalized. Generally, it needs to be customized for specific applications. Manufacturers in the industry generally obtain orders through bidding, and organize product design, production, installation and commissioning according to user needs. The manufacturing enterprise is mainly responsible for design and production of core components, and the supporting components are obtained by purchasing from professional manufacturers; the manufacturing enterprise assembles various core components and supporting components into products according to the requirements of the order. In this mode, core component production is carried out inside the production enterprise, which can ensure the control of technical know-how, and implement strict quality control processes in accordance with high quality standards. Product quality can be effectively guaranteed, but due to limited production capacity, The ability to accept orders is restricted to some extent.

3. Cyclical, regional or seasonal characteristics of the industry

With the improvement of national environmental protection requirements, the application demand of bag-type dust removal equipment is constantly expanding, and the industry is in a period of stable development with good growth momentum, and there are no obvious cyclical characteristics. As an effective means for controlling fine dust emissions, bag filters are widely used in more than 20 industries such as cement, steel, non-ferrous metals, electricity, machinery, chemical industry, and municipal services.48 The cyclicality of various downstream industries does not completely overlap, and can be certain. To some extent, the business fluctuations in this industry have been smoothed, and the cyclical fluctuations in some downstream industries have little impact on the market demand for bag dust removal equipment. Due to the relatively uneven distribution of customers in the downstream industries such as cement, steel, non-ferrous metals, and power, the customer's project location is the business location of the industry. Therefore, the industry has certain regional characteristics. At the same time, the industry does not have obvious seasonal characteristics.

The dust removal equipment is composed of a box body and foam generating equipment, a foam distributor, a foam nozzle and a bracket. This system is used in conjunction with a special foam dust suppression fluid for mines to effectively control dust in mining mining faces and tunnels.
