Description

Percussion flow gas purge system
Technical field
The present invention relates to air cleaning facility field, particularly relate to a kind of percussion flow gas purge system.
Background technology
Present urban air-quality worse and worse, people are also more and more stronger to the demand improving air quality, people are for pm2.5 (particulatematter, particle), namely in surrounding air, aerodynamics equivalent diameter is less than or equal to the particle of 2.5 μm (microns), also claims fine particle.This numerical value of pm2.5 is higher, and just to represent air pollution more serious.But in daily industrial production, the gas usually discharging a large amount of heterogeneity causes (comprising the solid particle, dust, organic pollutant etc. that pollute class) pollution of air;
Air purifier carries out classification by cleaning principle three kinds:
1, absorbent-type is filtered: utilize porous filter material, as (the strongest the working as of current adsorption capacity count HEPA high-density air filter material) such as non-woven fabrics, filter paper, fiber, foam cottons, suspended particulate in absorbed air, pernicious gas, thus purify air.2, electrostatic precipitation type: make pollutants in air charged by electrostatic, has then adsorbed the dirt in air of charged particle with dust collect plant trapping, has reached the object that purifies air.3, compound: to utilize filtration and electrostatic precipitation mode to purify air simultaneously.
Wherein: filter absorbent-type, such as: (1) adopts and considers material, consider plate, filter cylinders etc. have (it are comparatively obvious for particle rich) such as type gas film or active carbons, but it is of long duration, the film body of gas film is bound to the Particulate Pollution after by enrichment, thus the air after its process causes secondary pollution, and the film body of this gas film is non-renewable (because the particle of its attachment is often very little, composition is very complicated, but the gas film after cleaning equally also adheres to such particle, cannot continue to use), what is more important its to the air scale of construction and multicomponent gas cleaning more aobvious helpless.
Wherein, its process gaseous substance of electrostatic gas purifying equipment is very single, can not effectively be removed VOC.
Wherein, in compound gas purifying equipment, the main filtrate that adopts is prepared filter screen or filter cylinder and carries out enrichment in conjunction with electrostatic apparatus to the particle in air; Or (VOC material refers to the general name holding volatile organic substance at normal temperatures, common are formaldehyde, toluene and dimethylbenzene etc. to the VOC gas that contains of little a part of little gas flow to adopt some polar substances (such as: sulphur fiber leaching some chemical substance profound).) carry out degrading and removing; But still there is the technological deficiency of following several aspect in it: when gas film and electrostatic depuration structure composite use, windage is larger, it can not carry out high efficiency purification to the gas of the air scale of construction, treating capacity is very little, still there is a large amount of polluter in air can not be purified, its purified treatment efficiency is very low.Its process gas componant is also few; The middle sulfur dioxide of such as coal-fired air cannot be removed.
In the prior art as immediate technical scheme, relate to a kind of household kitchen oil smoke cleaning equipment (namely number of patent application is 03102035.6), its primary structure comprises anterior shock flow type gas-liquid reaction room 2 and the gas-liquid separation chamber at rear portion, wherein; The shock flow type gas-liquid reaction room 2 of upright placement comprises air inlet 21 and deflector I (i.e. the first deflector 23), bilateral symmetry is provided with deflector II (i.e. the second deflector 25), middle part forms air impingement district (chamber 24 of namely clashing), is impingement region outlet (i.e. exhaust outlet 22) bottom it; At least one pair of jet pipe is set in the space in this air impingement district; This is arranged in same plane in opposite directions to the spray-hole of jet pipe; The flange at the two ends of the first deflector 23 forms positive flow passage 26 and reverse flow passage 27 with the second deflector 25 of below respectively.Gas-liquid separation chamber, its top arranges a pair deflector III, form both sides gas discharge outlet, and form gas collection district at top, the middle part in this gas collection district is provided with outlet, this technical scheme has following characteristics, this solution provides a kind of high speed, initiatively, gas-liquid reactor, can be separated and enrichment with to trace constituent different in gas carrying out the higher reaction of efficiency compared with the air scale of construction within a short period of time.The program has following deficiency: 1. only carried out a gas-liquid contact to pending gas, can not carry out the gas-liquid contact of the degree of depth and Duo Bo time.2. a kind of liquid can only be adopted as gas-liquid contact media, reaction and separation processes enrichment process can not be carried out to the gas containing multiple heterogeneity.3. this technical scheme can not form efficiency light catalyst structure, thus very low to efficiency when carrying out chemical reaction containing the gas of different chemical composition.
