In the aspiration procedure of VOCs foul gas, if negative pressure is too low in cesspool, it is big to be bound to cause cesspool face oil gas
Amount evaporation, and subsequent treatment process is entered with the VOCs foul gas pumped out, treatment effect is influenced, to control cesspool
Interior negative pressure adds negative pressure adjusted and controlled system on cesspool top, and the negative pressure value measured by negative-pressure detector is adjusted to be adjusted on snorkel
The switch degree of valve maintains cesspool top negative pressure within the scope of one (between 0 to -100Pa).
Due to having a large amount of oil gas in petrifaction sewage VOCs foul gas, if without pretreatment, it certainly will be to subsequent
Treatment facility affects, first is that oil gas, aqueous vapor form oil emulsion under the high speed shear of draught fan impeller, causes draught fan impeller negative
Lotus increases, while oil emulsion trickling is difficult to clean off to ground, influences environment；Second is that oil gas, which largely condenses, is covered on biologic packing material table
Face influences Biochemical Treatment.Level-one oil catcher, second level oil catcher mainly using coalescence coarse principle, pass through little particle
Oil gas particle be attached in oil catcher in lipophile material and be gradually gathered into bulky grain oil droplet process removal VOCs stench
Oil gas in gas.
Preprocessor further removes the oil gas in VOCs foul gas on the basis of preceding two-stage oil catcher, prevent oil gas into
Enter combined bio filter tower, and be covered on biofilm surface, forms the contact that oil film prevents microorganism and organic exhaust gas and oxygen；
Simultaneously because water mist sprinkling can also play cooling effect, prevent burst high temperature (40 DEG C of >) gas from entering combined bio filter tower,
Influence the growth of microorganism, it is ensured that biochemical system can operate normally.
Preprocessor is by (gas) eddy flow+moisture film+spray washing mode, by the different shape of water to VOCs effluvium
Body carries out pretreatment and pre-add wet process.Fan outlet end is connected with preprocessor lower part side so that VOCs foul gas
Enter preprocessor from lower part side to rotary-cut, eddy flow rises in the straight tube honeycomb filler for being located at middle part and forms the small of multiple rotations
Air-flow；Spray head in reverse spraying nozzle and endless tube is arranged in top, and, inversely to air-stream spraying, water mist forms down-flow water on filler wall
Film and with air flow contacts, mass transfer.The collective effect of above-mentioned several measures keeps VOCs foul gas and water mist, moisture film in tower abundant
Contact, VOCs foul gas are cooled down, and are discharged into cesspool with shower water after oil gas condensation.
Due to petrifaction sewage VOCs foul gas complicated component, existing sulfur-containing compound, and there are hydro carbons, aromatic compound,
In order to reach preferable treatment effect, biological deodorizing system is using combined bio filter tower as biochemical processing process, combined type
Biological filtering tower combined working system " chitosan fluid dressing+bio-trickling layer " group technology, lower layer is biology drop filtering layer module, in bio-trickling layer module
Equipped with continuous spray equipment, upper layer is chitosan fluid dressing module, and chitosan fluid dressing module is equipped with interruption spray equipment.Upper and lower chitosan fluid dressing
Spray is provided the switch of signal control spray water control valve by the gas humidity survey meter for being mounted on chitosan fluid dressing module top, when
When discharge gas humidity is lower than 85%, closes lower layer's bio-trickling filter and spray water control valve, open upper layer chitosan fluid dressing shower water
Control valve；After 30min or humidity are continuously opened greater than 95%, closes upper layer chitosan fluid dressing and spray water control valve, it is raw to open lower layer
Object drips filtering layer and sprays water control valve.
VOCs foul gas from bottom to top successively passes through the chitosan fluid dressing mould combined by bio-trickling layer module, chitosan fluid dressing
Block, different pollutants in VOCs foul gas respectively at apposition growth on the biomembrane on porous surface biofilter material surface
Dominant bacteria contact, effectively degraded the pollutant in VOCs foul gas, especially benzene, first by the metabolism of microorganism
The water-soluble lesser substance such as benzene, dimethylbenzene.To cope with possibility that the following environmental requirement further increases and site environment
Further deteriorate, skid-mounted type VOCs foul gas processing unit can by the convenient increase advanced treatment process of module stacked system,
Get angry without scene, simple and quick construction, and do not increase land occupation.
In the specific implementation, 4 pipe of VOCs foul gas suction interts thoroughly collects dirt into sealing cesspool lamina tecti to the present invention
The VOCs foul gas of ullage in pond, while remaining metastable micro- negative in cesspool by negative pressure adjusted and controlled system
Pressure, it is ensured that VOCs foul gas is not excessive by centralized collection in cesspool, and reduces the evaporation capacity of oil gas VOCs to the greatest extent；It collects
VOCs foul gas handles through two-stage oil catcher and removes oil gas therein；By being sent through being pressurizeed by blower to pretreatment after fire arrester
Device, preprocessor carry out pretreatment and pre-add wet process to VOCs foul gas；By pretreated VOCs foul gas into
Natural diffuseness discharges after entering the processing of combined bio filter tower.Expansion advanced treating can be facilitated as needed.
The present invention and its embodiments have been described above, this description is no restricted, shown in the drawings
Only one of embodiments of the present invention, actual structure is not limited to this.All in all if the ordinary skill of this field
Personnel are enlightened by it, without departing from the spirit of the invention, are not inventively designed and the technical solution phase
As frame mode and embodiment, be within the scope of protection of the invention.
