Present invention spraying waste gas preprocess method, comprises the following steps：
The air inlet 11 of the first step, waste gas through Wet vertical waste gas pre-treating device 1 enters in tower body 10；
The Sprayer Circulation liquid that second step, waste gas spray with the shower nozzle 152 of spray thrower 15 is contacted, and realizes that gas-liquid is fully contacted, eddy flow tower
Disk 16 gets rid of the bulky grain coating cloud cyclonic separation in waste gas to material-storing box 17；
Specifically, waste gas up flows after entering in tower body 10, sequentially passes through multi-layer rotational flow tower tray 16 and the dust in waste gas
It is stained with weight after Sprayer Circulation liquid and becomes weight, so the coating cloud of bulky grain is by the centrifugal drying of blade 161 of eddy flow tower tray 16 to lower section
In material-storing box 17；I other words, Multi-layer sprinkling device 15 is staggered with eddy flow tower tray 16, can enable bulky grain coating cloud at this
Stage is divided；And the motion of eddy flow tower tray 16 can also cause void tower wind speed big, so that uniform gas-liquid distribution, is follow-up
Demisting layer random packing 13 work reduction difficulty；Sprayer Circulation liquid can also reduce the temperature of waste gas.
3rd step, waste gas complete coating cloud, the separation of water smoke by demisting layer random packing 13；
Specifically, up flowed with the waste gas after the processing of spray thrower 15 by eddy flow tower tray 16, by demisting layer filler
Enter demisting layer random packing 13 after eyelid retractor 14, the waste gas of demisting layer 13 pairs of entrance of random packing carries out coating cloud, water smoke
Separation, i.e. demisting layer random packing 13 absorb most of water smoke in waste gas.Because the top of demisting layer filler limiter 12
As reducing tower body end socket 101, so that the wind speed in demisting layer random packing 13 is small, in this way, effectively increasing demisting layer
The water smoke removal efficiency of random packing 13；Along with employing hump shape demisting layer packing support device 14, and hump shape demisting layer
Perforation 141 is also evenly arranged with packing support device 14 so that the air quantity of the wind by demisting layer random packing 13 it is uniform,
Wind speed is stable, so that when carrying out coating cloud, the separation of water smoke, all fillers all work, all water smoke is being absorbed, in this way, water smoke
Separating effect more preferably, and can delay the service life of filler, so as to reduce the usage amount of filler.And traditional demisting layer filler
Eyelid retractor is then slab lattice shape, so that when separating every time, the always lower sections of filler worked, the filler of upper part
Effect is not worked even less, so as to cause the filler life-span especially short, every being accomplished by changing filler soon so that filler is used
Amount is very big.
4th step, waste gas are through reducing tower body end socket 101 from the discharge of air outlet 18 of Wet vertical waste gas pre-treating device 1
Enter dry method horizontal waste gas advanced treatment apparatus 2 afterwards；
The small size particle coating cloud that 5th step, the grade one filter 23 of dry method horizontal waste gas advanced treatment apparatus 2 are gone in removing exhaust gas
Impurity；
6th step, the secondary filter 25 of dry method horizontal waste gas advanced treatment apparatus 2 get rid of the water smoke in waste gas；
7th step, the secondary filter 25 of dry method horizontal waste gas advanced treatment apparatus 2 get rid of the fine particle impurity in waste gas.
As shown in Figure 10, the waste gas after the spraying waste gas preprocess method processing enter photocatalysis below, etc.
The subsequent purification processing units 3 such as gas ions, activated carbon/zeolite/molecular sieve adsorption, burning, carry out the purified treatment of waste gas, pass through
Gas after purified treatment is discharged in air through air-introduced machine 4.
