Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is further elaborated below in conjunction with the accompanying drawings：
Because the species of industrial waste gas is various, the composition of the waste gas that all trades and professions are produced differs, therefore the utility model master
If carrying out purified treatment for the industrial waste gas that coal-fired, fuel oil thermal power plant produces.This kind of industrial waste gas mainly contains ickings, oil
Fat, soot, NOx(such as NO, NO2Deng), SO2, CO and hydrocarbon.
A kind of industrial waste gas processing system as shown in Figure 1, including set gradually along the direction that industrial waste gas is conveyed
Dust arrester 1, oxidation catalytic converter 2, except soot filter 3, denitrification device 4 and desulfurizing device 5.
Dust arrester 1 we can select on the market often after electrostatic precipitator or other cleaners, in this implementation
In example, dust arrester 1 includes the metal filter screen 11 being arranged in closed box, because dust arrester 1 herein mainly goes
Except larger ickings of particle etc., thus we use metal filter screen 11, the mesh number of metal filter screen 11 between 60~180,
Metal filter screen 11 is obliquely installed, i.e. horizontal by certain angle, the bottom of closed box is provided with metal filter screen 11
Dust-collecting box 12.The purpose that metal filter screen 11 is obliquely installed is to make to be easier to fall into dust by the break flour that metal filter screen 11 stops
In box 12.
CO and hydrocarbon in industrial waste gas is converted into CO by oxidation catalytic converter 2 using the effect of catalyst2
And water, catalyst is using metal platinum, palladium or rhodium.
Include more than 2 pieces set along the superposition of industrial waste gas conveying direction of heat-stable ceramic brick except soot filter 3
31.In the present embodiment, heat-stable ceramic brick 31 is made of carborundum.Heat-stable ceramic brick 31 is covered with honeycomb hole, and industrial waste gas exists
During by these honeycomb holes, the carbon particle in soot can be sticked on heat-stable ceramic brick 31, so as to reach removal industrial waste gas in
Soot purpose, reach the effect of purification gas.In use for some time, honeycomb hole can gradually be blocked heat-stable ceramic brick 31
Plug, so as to gradually fail.In order to solve this problem, in the present embodiment, we are at except the gas outlet of soot filter 3
Be provided with a flow sensor 6, the flow sensor 6 is used to detecting the flow of gas, and the bottom of heat-stable ceramic brick 31 and/
Or surrounding is provided with heating arrangements 32.In the present embodiment, heating arrangements 32 use electrical heating wire, certainly in actual use,
We can also be according to the physical condition of production using other methods such as gas heatings.During use, work as flow sensing
Device 6 detect gas flow it is smaller when, just can determine whether on heat-stable ceramic brick 31 honeycomb hole major part plugged by carbon particle,
Heating arrangements 32 can now be started to heat heat-stable ceramic brick 31, so as to the carbon particle on heat-stable ceramic brick 31 be burnt
Fall, heat-stable ceramic brick 31 is recovered the function of filtering.
