Change equipment and its application.
Background technology
Volatile organic matter (VOCs) refers to participating in the organic compound of atmospheric photochemical reaction, including non-methane hydrocarbon
(alkane, alkene, alkynes, aromatic hydrocarbon etc.), chlorinated organics, itrogenous organic substance, contains oxygen-bearing organic matter (aldehyde, ketone, alcohol, ether etc.)
Sulfur organic etc. is to form ozone (O3) and fine particle (PM2.5) pollution important as precursors object.The sources VOCs are wide, harm is big,
Difficult, China extremely payes attention to the improvement of VOCs, and VOCs control technologies are broadly divided into solvent absorption, absorption at present
Method, condensing recovery, low-temperature plasma, UV photodissociation, combustion method and bioanalysis, condensing recovery method is due to being only limitted to the useless of single component
Gas, application range are limited；Solvent absorption, low-temperature plasma, UV photodissociation treatment effeciencies are extremely low, are also easy to produce ozone or small molecule etc.
Pollutant, therefore, it is difficult to promote and apply.
Compared with Traditional materialized method (such as absorption method, combustion method), bioanalysis has easy to operate, economical and efficient, nothing
The features such as secondary pollution, becomes the emerging focus of VOCs improvement.It is common for biology drop in the equipment of Biochemical method VOCs
Equipment is filtered, in the engineering process that VOCs is handled due to biological island, exhaust gas need to be adjusted to the condition of suitable micro-organisms growth, example
Such as：PH value is 6~8, temperature is 25~35 DEG C, and exhaust gas temperature and pH are not necessarily met the requirements in project treatment, is given up simultaneously
Dust can also be carried in gas secretly, therefore must be pre-processed before exhaust gas enters biological case, the pretreated purpose is removal
PH and temperature are adjusted to the condition of suitable micro-organisms growth by dust, particle in exhaust gas.The pre- place of VOCs exhaust gas in the prior art
Reason generally using the wet treatment method of spray, carries out in special pre-processing device, then will be pre-processed with gas piping
Equipment is connect with bio-trickling case, and VOCs engineering exhaust gas, into bio-trickling case, is dropped after pre-processing device by microorganism
Solution.But current this method takes up a large area, the equipment that uses is more and special VOCs exhaust pipes is needed to connect,
Processing procedure is easy pollution.

7.5, the waste liquid of preprocessing module is discharged by the first leakage fluid dram；Pretreated exhaust gas passes through second baffle and second
The gas passage of baffle composition enters bio-trickling module, exhaust gas in bio-trickling module from bottom to top by polyurethane filler,
The microorganism species of absorption degradation VOCs gases on polyurethane filler, exhaust gas is after the degradation of microorganism species, by gas outlet
Discharge, in exhaust gas is by bio-trickling module process, the downward Sprayer Circulation nutrient solution of the second spray port, spray rate
0.45m3The waste liquid of/h, bio-trickling module are discharged by the second leakage fluid dram.
The floor space of whole equipment is 15m2, the residence time of exhaust-gas treatment is 15s, treatment effeciency 91%.
Comparative example 1
The separated abatement equipment of existing conventional pretreatment and bio-trickling is 4000m for processing air quantity3/ h's is useless
Gas, pollutant are ammonia, hydrogen sulfide, methyl mercaptan, 200~600mg/m of concentration3, floor space 20m2, treatment effeciency 92%.
By above-described embodiment it is found that bio-trickling integration apparatus provided by the invention realizes in same main box
The pretreatment of VOCs gases and bio-trickling simplify entire processing unit, reduce the floor space of entire processing unit, contracting
Short VOCs gases by the time, improve the treatment effeciency of VOCs gases.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
