Abstract

The technology belongs to the field of air purification, and specifically relates to a method for purifying soot and foul gas, which is suitable for purifying all foul gases such as polluted gas, oil fume, soot, and dust. The outlet of the fan injects the dirty gas from the upper end of the clean room into the clean room, and the water spray device drops the water from top to bottom in the form of spray or atomized water. The mesh-shaped partition falls, and the dirty gas is fully washed into clean gas by spray or atomized water, and is discharged from the exhaust port at the lower end of the purification chamber. There is a vertical drop between the air inlet and the exhaust port; Connected to the water outlet, the water outlet of the water pump transports the water to the water spray device through the return pipe for reuse. The invention utilizes the method of forcibly cutting the gas and repeatedly washing it by the mesh-shaped partition, so that the dirty gas is purified very cleanly; at the same time, because the gravity of the water is used to drop the washing gas, the power consumption is very small, and the purpose of high efficiency and low cost is achieved. .

Description

Flue dust and dirty method for gas purification

Technical field:

This technology belongs to air purification field, in particulars relate to a kind of flue dust and dirty method for gas purification, is suitable for dirt Contaminate the purification of all dirty gases of gas, oil smoke, flue dust, dust etc.

Background technique:

Currently, there are two main classes: the first kind: active purification class (no filter screen type) for dirty gas and fume purifying mode. Main operational principle: charging pollutants in air by corona discharge, traps charged particle using dust collect plant, reaches purification The purpose of air.Silver ion technology, anion technology, low-temperature plasma skill can be divided into according to the active sterilizing mechanisms of these products Art, photocatalyst technology and net cluster ion ion technology.This purification style is at high cost, is also unsuitable for the gas of excessive dirt.The Two classes: spray equipment washes dirty gas, but this mode can not sufficiently be divided due to dirty gas, so only The effect is relatively poor for change；During some spray cleanings are provided with mesh interlayer, but purpose is primarily to decline shower water It can be evenly distributed, not have the purpose for making uprising gas constantly be cut into minute bubbles by mesh and being washed with water in time.Above two Kind purification style all haves the shortcomings that at high cost, structure is complicated, degree of purification is not high.The present inventor has a patent " multistage Mesh dirt gas cleaning plant ", the patent No.: ZL 201621459385.9 is disclosed poroid with spraying atomizing device screening Interlayer filtration, purification dirt gas, but since the technology is using by the way of bottom input dirt gas, it needs in clean room Purification gas could be sucked out using the exhaust fan of relatively high power for side, and therefore, the present invention is exactly to overcome lacking for a upper patent Fall into design.

Summary of the invention:

The present invention is set in clean room top setting water injector and dirty gas inlet, while in purification indoor horizontal Mesh interlayer is set, achievees the purpose that make dirty gas to be sprayed or atomized water washing, purifying gas by force.

It realizes the technical solution used in the present invention is: dirty gas is injected from clean room upper end and purified by the outlet of blower Room, water injector, by water by spray or atomized water in the form of fall from top to bottom, dirty gas and spray or atomized water mixing, It falls commonly through multistage mesh interlayer, dirty gas is sprayed or atomized water is sufficiently washed at clean gas, from clean room The discharge of lower end exhaust outlet, air inlet and exhaust outlet have normal throw；The water injector spray water column, water mist one of which or Two kinds of mixture；Lower end exhaust outlet is higher than the ponding water surface, and water pump inlet is connected to water outlet by water return pipeline, and water pumps out Water end (W.E.) is delivered water at water injector by water return pipeline and is reused；There is filler in clean room upper end, for adding clear water, Sewage draining exit is arranged at the bottom of clean room, for sewage to be discharged；Under the premise of guaranteeing that air inlet and exhaust outlet have normal throw, purification Room is arbitrary shape.

Detailed description of the invention:

This technology is further illustrated with reference to the accompanying drawing.

Fig. 1 is flue dust and dirty method for gas purification cross-sectional schematic schematic diagram.

Fig. 2 is the diagrammatic cross-section that clean room is arbitrary shape.

In figure, 1. blowers, 2. air inlets, 3. dirty gases, 4. clean rooms, 5. mesh interlayers, 6. gas outlets, 7. water spray dresses It sets, 8. sprays or atomized water, 9. water pumps, 10 clean gas, 11. water outlets, 12. water return pipelines, the 13. ponding waters surface, 14. add water Mouthful, 15. sewage draining exits.

Specific embodiment:

In Fig. 2, dirty gas 3 is injected clean room 4 from 4 upper end of clean room by the outlet of blower 1, water injector 7 by water with The form of spray or atomized water 8 is fallen from top to bottom, and dirty gas 3 and spray or atomized water 8 mix, commonly through multistage mesh Shape interlayer 5 falls, and dirty gas 3 is sprayed or atomized water 8 is sufficiently washed at clean gas 10, from 4 lower end exhaust outlet 6 of clean room Discharge, air inlet 2 and exhaust outlet 6 have normal throw；The water injector 7 sprays water column, the one of which of water mist or two kinds Mixture；Lower end exhaust outlet 6 is higher than the ponding water surface 13, and 9 water inlet end of water pump is connected to water outlet 11, water pump by water return pipeline 12 9 water outlets are delivered water at water injector 7 by water return pipeline 12 and are reused；There is filler 14 in 4 upper end of clean room, is used for Clear water is added, sewage draining exit 15 is arranged at the bottom of clean room 4, for sewage to be discharged.

In Fig. 2, clean room 4 is the closure container of arbitrary shape, and there is water injector 7 in 4 upper end of clean room, sprays water column or water Mist, there are also air inlet 2, dirty gases thus to enter and be washed by water column or water mist for 4 upper end of clean room, passes through mesh interlayer 5 It falls to bottom.Air inlet 2 has normal throw in 4 lower end of clean room, the two in 4 upper end of clean room, gas outlet 6.
