Description
Technical field
The present invention relates to technical field of waste gas treatment, in particular to a kind of VOCs biological treating equipment.
Background technique
VOCs biologic treating technique is risen first in Holland and Germany, is for not only non-recovery value but also serious pollution environment
Middle low-concentration organic exhaust gas processing and develop, be particularly suitable for the processing of low concentration, big flow gas.Biology drop at present
Worry method is most widely used and effect is best, but still not can avoid the short stream of gas, filler blocking, the problems such as void tower flow velocity is big.
Common biology drop considers tower gas flow for section stream, i.e., cuts using the cross-sectional area of biological tower as the circulation of air-flow
Face, in the case where there is filler filling, gas actual circulation section can be further reduced, and so cause gas flow rate larger, exhaust gas
With filler and liquid insufficient contact, the clean-up effect of exhaust gas is seriously affected.If reducing gas flow rate, it is necessary to expand stream
Logical section causes biological tower volume to need further expansion, but the degree very little that gas cross section flow velocity reduces, it is difficult to significantly
Promote the clean-up effect of exhaust gas.
In addition, existing biology drop considers the filler in tower generally using mode is huddled, this requires fillers to have
It is light-weight, the high feature of intensity.Existing filler generally uses the substances such as sawdust, haydite, and the outer surface of filler is stained with biology
Film, in biggish gas-liquid flow velocity, biomembrane renewal speed is too fast to be caused to fall off seriously, and the biomembrane to fall off can not be timely
It degrades and accumulates, the biomembrane of accumulation can hinder gas circulation that air resistance is caused to increase, and gradually increase filler layer weight；
After running a period of time, since falling off for biomembrane causes packing layer to aggravate, and due to durability issues, this body structure of filler meets with
It is crushed to destruction or is gradually compacted, further result in resistance increase, therefore the two causes vicious circle, packing layer is fast
Speed deteriorates.In addition, it is inhomogenous using pore size between the filler for the mode that huddles, it is easy to make the short stream of gas, the gas treatment of short stream
Effect is poor, reduces biological treatment effect.

Pipe 8 protrudes into water storage tank 51.In actual application, there is a large amount of suspension microorganism in water storage tank 51, pass through aeration tube 8
The aeration aerating into water storage tank 51 creates aerobic condition, so that microorganism is continued degradation and completes degradation not in loading pipe 3
Pollutant.
The working principle of the invention and preferred embodiment is described below.
VOCs biological treating equipment 100 of the invention can use the structure type of tower body, in certain applications, this hair
Bright VOCs biological treating equipment 100 can also be referred to as biological tower.Wherein, sink 22 above-mentioned, discharge chamber 103, packing cavity 6
It can be set gradually from top to bottom with air-inlet cavity 5.Sometimes water storage tank 51 can also be referred to as biological cycle water tank, discharge chamber
103 are referred to as air outlet box, and packing cavity 6 is referred to as packing layer, and air-inlet cavity 5 is referred to as inlet box.VOCs biological treating of the present invention is set
Standby 100 main body load bearing manner can use steel structure column, Liang Zuowei main support.1 inside supporting point of casing is respectively positioned on crossbeam
On, it is ensured that tower structure is firm.Biological tower periphery steel plate is connected with each other using plate folding type, is increased greatly through folded plate is powerful
Add, therefore pass through the connection of plate and plate, plate and crossbeam, plate and structural column, crossbeam and structural column, the outer knot of biological tower can be formed
Structure, and accordingly enclose into inlet box, packing layer and air outlet box region.
Biological cycle water tank is located at biological tower bottom, by the welded connecting between plate at cube water storage, biological cycle
Water tank bottom is furnished with aeration tube 8, and aeration tube 8 is the form of PVC water pipe opening, is uniformly exposed to entire biological cycle water tank
Gas.After steel plate folds at the top of biological cycle water tank surrounding, it is connect with the steel plate of inlet box periphery.Inlet box upper end connecting cross beam,
And the supporting elements such as square tube are welded on crossbeam, it is laid with packing layer bottom plate (first partition 4 i.e. above-mentioned) in square tube, filler is with bottom plate
As bearing, filler stacked in multi-layers, usual packing layer is laid with 3 ~ 4 layers, 3 ~ 4 meters of bed stuffing height；Packing layer top square tube, angle
The profiles such as iron are fixed on second partition 7, avoid packing layer (loading pipe 3 i.e. above-mentioned) crooked.It is outlet air above packing layer
Case (discharge chamber 103 i.e. above-mentioned), gas discharge after collecting in air outlet box from exhaust outlet 102.Cover board is laid at the top of air outlet box,
Cover board is through folded convex steel plate, and cover board is overlapped laying two-by-two and guarantees biological tower Integral sealing.Overhead water is placed on cover board
Slot 22(, that is, sink 22 above-mentioned), PVC water pipe (water supplying pipe 21 i.e. above-mentioned) is connected after 22 aperture of sink as the confession of each loading pipe 3
Water, each sink 22 are that two rows of biologic packing material pipes 3 supply water.
Working principle: overall to be divided into gas process and liquid flow.Gas process is as follows: exhaust gas enters from air inlet 101
Afterwards, after inlet box (air-inlet cavity 5 i.e. above-mentioned) is pressed, each loading pipe 3 is entered by bottom plate (first partition 4 i.e. above-mentioned),
Exhaust gas is spread around in loading pipe 3 under the influence of air pressure, and gas is micro- with filler surface during slow diffusion
Biology and the liquid of decline come into full contact with, and complete dissolution, the adsorption process of pollutant, are then bioavailable degradation.Work as exhaust gas
In pollutant dissolution after, gas i.e. be purified, go out after gas radially diffuses to 3 periphery of loading pipe from center from first
Port is detached from, and purified gas collects in the gap between loading pipe 3 and loading pipe 3 and to rise to air outlet box (i.e. aforementioned
Discharge chamber 103), leave biological tower qualified discharge through exhaust outlet 102.Liquid flow is as follows: tower bottom water tank (water storage i.e. above-mentioned
Slot 51) interior biological cycle water through pipeline pump is delivered to biological tower tower top sink 22, and liquid is (i.e. aforementioned through downspout in sink 22
Water supplying pipe 21) gravity flow enters in loading pipe 3, flows through from top to down between upper and lower level filler also by self-flowing effect all
Filler eventually arrives at the outflow of filler bottom, and the liquid of outflow is through the downspout of bottom plate (i.e. first partition 4) or through filler hollow portion
It is diverted into biological tower water tank (i.e. water storage tank 51), liquid recycles always since then.Still there are a large amount of suspension microorganisms in biological water tank,
Aeration aerating is carried out to water tank, creates aerobic condition, microorganism is made to continue the pollutant that degradation is not completed in degradation in packing layer.
What needs to be explained here is that: in the absence of conflict, those skilled in the art can according to the actual situation by
Relevant technical characteristic is combined with each other in above-mentioned each example, to reach corresponding technical effect, particularly for various combined situations
It will not repeat them here.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
