The specific embodiment
Below in conjunction with drawings and Examples the specific embodiment of the present utility model is described: waste gas enters from the bottom of chemical processor and biological processor, and by reverse process.A kind of toxic harmful exhaust gas treating apparatus as shown in drawings, comprise exhaust gas collector, ventilation shaft, biological processor, chemical processor, via ventilation shaft, be connected in sequence, chemical processor includes caustic wash tower 8, alkali cleaning circulating pump 11 and alkali-prepared tank 10.Alkali-prepared tank 10 is connected with alkali cleaning circulating pump 11 inlet ducts, and 11 outlets of alkali cleaning circulating pump link to each other with the alkali liquor inlet of caustic wash tower 8; This caustic wash tower 8 is valve tower, and alkali liquor inlet is arranged at its top, and the bottom has with ventilation shaft and is connected, and also has waste liquid outlet at the bottom of caustic wash tower 8 towers; Biological processor 9 is square structure, is provided with spaced order reaction chambers 3 mutually in the tower, loads floating filler layer 12; All be provided with spray head 13 above every layer, biological processor can be one or more parallel connections.
Exhaust gas collector gas collection part mainly is made up of fume trap cover 1, ventilation shaft 2, provides negative pressure by centrifugal blower 18, and import is provided with poisonous gas concentration monitor instrument 3, and outlet is established and is positioned at optimal working point when valve makes blower fan work with the regulating system air quantity.
When biological tower need spray, water was promoted through spray by spray water pump 18 and is responsible for 15, is sprayed onto on the floating filler layer 12 from shower nozzle 13.
Caustic wash tower 8 is the accident emergency device, and it places biological processor 9 front ends, switches by caustic wash tower air intake valve 4 and valve 5; Mainly formed by caustic wash tower 8, inlet valve 4, alkali cleaning circulating pump 11, alkali-prepared tank 10.
Treating apparatus operation principle and the course of work of toxic harmful exhaust gas of the present utility model are: under the draft of blower fan 19, near fume trap cover 1, form negative pressure region, each pollution sources toxic and harmful enters in the ventilation shaft 2, accept the check of fans entrance place concentration of toxic gases measuring instrument 3, concentration of toxic gases measuring instrument 3 is sent to main control to data signal, when H2S concentration＞800mg/m3, master-control room starts the accident emergency system, namely sending instruction starts NaOH solution circulating pump 11 and aspirates alkali lye get in the caustic wash tower 8 from alkali-prepared tank 10, close valve 5 on the trunk line 20 simultaneously in this, open caustic wash tower inlet valve 4, waste gas is directed in the caustic wash tower and the reverse neutralization of alkali lye of spray, then under the blower fan outlet pressure, enter in the trunk line 20, begin to enter the processing unit of biological processor 9, enter into trunk line 20 from top vent after waste gas is absorbed by the biodegradation oxidation and be discharged to atmosphere through the discharging tower; Wherein, the spray head work of each top, order reaction chamber is carried out synchronously.
In the whole waste gas treatment process fulfillment process, the metabolite that biological tower produces and the blowdown of caustic wash tower store by the water leg that is arranged on biological processor 9 bottoms, regularly by magnetic valve A16 discharging, shower water regularly enters water leg by magnetic valve B21 in the biological processor 9.
Device breaks down and can't move or when needing repair and maintenance, close caustic wash tower air intake valve 4, biological processor intake valve 6, and Open valve 5 and surmount pipeline valve 7, and waste gas can directly efflux by surmounting pipeline.
For preventing ventilation shaft discharge tail gas dewfall, form water smoke, even when low temperature, freeze and influence exhaust emissions efficient, except doing at exhaust chimney the insulation processing, establish the dew tapping equipment in the chimney bottom, because gravity flows into the dew tapping equipment, steam pipe 24 provides steam to dew from ventilation shaft outlet 23; Dew enters the municipal drainage pipeline by dew delivery pipe 25.
The above; be preferable case study on implementation of the present utility model; be not that the utility model is imposed any restrictions; every any simple modification, change and equivalent structure of above embodiment being done according to the utility model technical spirit changes, and all still belongs in the protection domain of technical solutions of the utility model.
