Technical Field

[0001] This utility model specifically relates to the field of filter technology, and more specifically to a filter mechanism for dust collection and recycling. Background Technology

[0002] In industrial production sectors such as metallurgy, chemicals, building materials, and machinery manufacturing, large amounts of dust-laden gases are generated during production processes. If these dust-laden gases are directly released into the atmosphere, they will cause serious air pollution, harming the ecological environment and human health, while also wasting useful materials. Therefore, dust collection and recovery of these gases is an indispensable part of industrial production.

[0003] Traditional single dust removal equipment, such as simple water film dust collectors, can capture dust to a certain extent, but their filtration effect on fine dust is often not ideal and it is difficult to meet increasingly stringent environmental emission standards. On the other hand, simple cartridge dust collectors are prone to problems such as cartridge clogging and difficulty in cleaning when dealing with high humidity and high dust content gases, and the impact of dust in the early stage will also shorten the service life of the cartridges.

[0004] To overcome the shortcomings of single dust removal equipment and meet the demand for efficient and stable dust removal of dust-laden gases in industrial production, and to achieve effective dust recovery, this filter integrates a water film dust removal mechanism and a cartridge dust removal mechanism, forming a composite dust collection and recovery treatment device. It aims to combine the advantages of water film dust removal and cartridge dust removal to improve dust removal efficiency, expand the applicability of the equipment, extend the service life of the equipment, and reduce operation and maintenance costs.

[0023] By adopting the above technical solution, the water film dust removal mechanism 1 performs preliminary dust removal and the filter cartridge dust removal mechanism 2 performs fine filtration, achieving good collection effects for dust of different particle sizes and meeting strict environmental emission standards. The dust collected by the water film dust removal mechanism 1 and the filter cartridge dust removal mechanism 2 can be discharged centrally through their respective ash discharge valves and air outlets 212, facilitating dust recycling and improving resource utilization. It can handle both dry dust-laden gas and gas with high humidity and high dust content. The water film pre-dust removal can reduce the direct impact of dust on the filter cartridge and the risk of clogging, expanding the applicable operating conditions of the equipment.

[0024] In this embodiment, the right end of the air inlet 18 is connected to the left end of the air intake channel 24, the right end of the air intake channel 24 is connected to the air inlet of the blower 23, the blower 23 is fixedly installed on the upper end of the filter box 22, and a ventilation opening is provided at the connection between the blower 23 and the upper end of the filter box 22; the lower end of the filter box 22 is fixedly installed on the equipment bracket 21. An air source tank 25 is fixedly installed on the right side of the filter box 22. A pulse valve is symmetrically installed on the upper end of the air source tank 25. The left side of the symmetrically arranged pulse valve is connected to the symmetrically arranged pulse pipe 26. The symmetrically arranged pulse pipe 26 is located on the inner side of the upper end of the filter box 22.

[0025] By adopting the above technical solution, the water film dust removal mechanism 1 pre-removes large particles of dust, reduces the dust load on the filter cartridge 28, and extends the service life of the filter cartridge; the equipped air source tank 25 and pulse pipeline 26 can effectively clean the dust on the surface of the filter cartridge 28, further ensuring the long-term stable operation of the filter cartridge 28.

[0026] In this embodiment, the pulse pipes 26 arranged symmetrically are provided with multiple filter cartridges 28 at their lower ends. The multiple filter cartridges 28 are fixedly installed inside the filter box 22 by mounting plate 27. An inspection door 29 is fixedly installed on the right side of the filter box 22, and the inspection door 29 is located at the lower end of the gas source tank 25. The filter housing 22 is fixedly installed with an air outlet chamber 211 at the lower end, and an air outlet 212 is fixedly installed at the lower end of the air outlet chamber 211; the equipment support 21 is provided with a maintenance ladder 210 on the right side.

[0028] The working principle of this utility model is as follows: Dust-laden gas enters the main body cylinder 12 through the dust inlet 13, and first passes through the spraying action of the lower spray water film assembly 14 and the upper spray water film assembly 15; the water mist sprayed by the water film assembly forms a water film, and the dust-laden gas comes into full contact with the water film, and larger dust particles are captured by the water film, achieving preliminary dust removal; the gas after water film dust removal rises into the exhaust box 16, and undergoes further preliminary filtration through the filter module 17, intercepting some fine dust; After preliminary filtration, the gas enters the filter housing 22 of the cartridge dust collector through the air inlet 18 and the air intake channel 24, and then undergoes fine filtration through multiple filter cartridges 28. The filter media of the filter cartridges 28 can efficiently intercept fine dust, thus deeply purifying the gas. The clean gas filtered by the filter cartridges is discharged from the exhaust port 212 of the exhaust fan by the action of the exhaust fan 23. The dust captured by the lower spray water film assembly 14, the upper spray water film assembly 15 and the filter cartridges 28 falls to the bottom of the equipment with the water flow or by its own gravity in the lower spray water film assembly 14 and the upper spray water film assembly 15, and adheres to the filter cartridges 28 in the cartridge dust collector 2. The filtered air is discharged through the exhaust port 212. The air source tank 25 provides compressed air, which is controlled by the pulse valve on the pulse pipeline 26 to periodically perform pulse cleaning of the filter cartridges 28, blowing the dust attached to the surface of the filter cartridges to the exhaust chamber 211, ensuring the filtration efficiency and service life of the filter cartridges. Through the preliminary dust removal of the water film dust removal mechanism 1 and the fine filtration of the cartridge dust removal mechanism 2, the equipment has a good collection effect on dust of different particle sizes, which can meet the strict environmental emission standards. The dust collected by the water film dust removal mechanism 1 and the cartridge dust removal mechanism 2 can be discharged centrally through their respective ash discharge valves and air outlets 212, which facilitates the recycling of dust and improves the utilization rate of resources. It can handle both dry dust-laden gas and gas with high humidity and high dust content. The water film pre-dust removal can reduce the direct impact of dust on the cartridge and the risk of clogging, thus expanding the applicable operating conditions of the equipment. The water film dust removal mechanism 1 pre-removes large particles of dust, reducing the dust load on the filter cartridge 28 and extending its service life. The equipped air source tank 25 and pulse pipeline 26 can effectively clean the dust on the surface of the filter cartridge 28, further ensuring the long-term stable operation of the filter cartridge 28. The inspection door 29 on the right side of the filter housing 22 and the multiple inspection ports on the main body 12 facilitate daily inspection, maintenance and filter cartridge replacement of the equipment; the maintenance ladder 210 on the right side of the equipment support 21 provides a safe and convenient maintenance passage for operators.
