Submicron water film deduster

Abstract

The invention discloses a submicron water film deduster. The submicron water film deduster comprises a dedusting chamber 1, a submicron water film purifying module 10, a nozzle 8, and an air outlet 11; the submicron water film purifying module 10 is composed of a plurality of dedusting plates 12 through laminating, or dedusting plates and a plate sandwiched by the dedusting plates, wherein the plate is composed of one or a plurality of materials selected from active carbon fibrofelt, active carbon fiber cotton, active carbon sponge, and active carbon particle net; water film 9 is formed on a side surface of the submicron water film purifying module 10 uniformly by water sprayed by the nozzle 8, so that dust-containing gas introduced into the dedusting chamber is delivered through the waterfilm 9 and the submicron water film purifying module 10 for purifying, and then is discharged through the air outlet 11. The dust-containing gas introduced into the dedusting chamber is delivered through the water film 9 and the submicron water film purifying module 10, leakage of no unpurified gas through water film uncovered parts is avoided, 99.9% or more dust is removed via filtering, and dust content is reduced to be lower than 3mg / <3>.

Description

technical field [0001] The invention relates to a wet dust collector in the dust collector industry, in particular to a submicron water film dust collector capable of efficiently removing respirable dust. Background technique [0002] In industrial production, a large amount of dust particles will be produced, such as a large amount of sintering smoke generated during sintering production in the metallurgical ironmaking industry, dust generated by mining, dust generated by cement production, and a large amount of metal particle debris generated by machine grinding in the production workshop , dust generated during grain storage and transportation, etc., if these smoke and dust are not processed and discharged directly into the atmosphere, they will cause huge pollution to the environment. [0003] Existing dust removal and purification equipment generally have a series of problems such as insufficient purification accuracy, single type of smoke and dust, short service life, ...

AI Technical Summary

Problems solved by technology

[0003] The existing dust removal and purification equipment generally has a series of problems such as insufficient purification accuracy, single type of dust treatment, short service life, and the use of a large number of consumables to cause secondary pollution to the environment.

For example, bag filter cartridge dust removal cannot handle wet, viscous and corrosive smoke, and there are a large number of consumables in the regular replacement of bag filter cartridges; electrostatic precipitator has low purification efficiency for dust with too large or too small specific resistance, and there are large equipment, many consumables, and energy consumption. Advanced problems; low efficiency of gravitational inertial dust removal and inability to purify tiny inhalable particles; low utilization rate of water mist dust removal equipment, which is very likely to have poor filtering effect under high flow rate of smoke and dust, and water mist will consume a lot of water resources. After vacuuming The generated sewage will also cause secondary pollution of the environment; the water film dust collector that uses the opposite direction of gas and water flow to increase the contact area will also have smoke, especially high-speed smoke, that is discharged from the space that the water film cannot cover and cannot be completely purified question
