Abstract

The utility model provides a special deodorization device for treating sewage or disposing filthy mud/trash. In the course for treating sewage or disposing filthy mud/trash, a lot of harmful gases (NH3, H2S, VOC, and the like) are generated, a special device is required to effectively remove the harmful gases, and discharged gases are ensured not to cause secondary pollution for the surrounding environment. According to working procedures, the special deodorization device comprises four sections: a submersion washing section, an adsorption section of inert filler, an adsorption section of active filler, and a spray washing section. The special deodorization device comprises a shell, a spray pump, a gas distribution device, an inert filler layer, an active filler layer, a spray nozzle, a discharge outlet, an overflow pipe, a blow-down pipe, and the like. Compared with the prior art, the four-section combined type biological deodorization device has the maximal characteristic that the two-stage washing and the two-stage adsorption are centralized in the same device, the performance is complementary, and meanwhile, the interaction effect is avoided. Aiming at the characteristic of deodorization in the course for treating sewage or disposing filthy mud/trash, the utility model has high efficiency, stability and service life extension, and avoids the failure of the filler due to acidification and basification.

Description

Four segments combined biological deodorizing equipment

Technical field

The utility model relates to sewage disposal or the special-purpose odor removal of mud/refuse disposal, specifically a kind of two-stage washing and two sections absorption are integrated in one, pernicious gas is to prevent the special equipment of secondary pollution in removal sewage disposal or the mud/refuse disposal process.

Background technology

In sewage disposal or mud/refuse disposal process, produce a large amount of pernicious gas (NH ₃, H ₂S, VOC etc.), need special equipment with its effective removal, guarantee that the gas that gives off can not cause secondary pollution to surrounding environment.Existing industrialization deodorization technology mainly is divided into biotechnology and chemical technology: chemical technology mainly is to utilize the chemical action between cleaning solution and the foul smell main component to finish deodorisation process; Biotechnology is divided into biofilter technology and bio-trickling filter, the biofilter is that the biomembrane of hanging utilizes filler self to provide nutrient to carry out metabolic deodorisation process on the biologic packing material, and bio-trickling filter is to hang the biomembrane utilization on the filler to add nutriment and provide nutrient to carry out metabolic deodorisation process.More than several technology have characteristics separately, have each other and have repellency, therefore can't bring into play combined effect in actual applications.

Summary of the invention

The purpose of this utility model provides a kind of in sewage disposal or mud/refuse disposal process, utilizes multi-biological absorption and chemical washing effect to finish the device of deodorizing purpose, reduces the secondary pollution that environment is caused.

The structure of the utility model odor removal is divided into parts such as housing, spray pump, gas pipe, inert filler layer, active filler layer, spray nozzle, floss hole, overflow pipe, blow-down pipe.The gas pipe that housing bottom setting is connected with air inlet pipe, gas pipe adopt the gas cutting along design, and the gas pipe material adopts the anticorrosion or stainless steel of carbon steel.The gas pipe top sets gradually inert filler layer and active filler layer, and the inert filler layer adopts the spherical inert filler of specification more than 2 kinds, and different size filler diameter satisfies the space geometry matching relationship.Active filler layer upper left side is provided with spray nozzle, and the spray nozzle situation adopts upper-spraying type.Spray nozzle links to each other with the spray pump of hull outside, and unnecessary spray liquid is discharged by the overflow pipe of housing bottom, and spray nozzle top is provided with the exhaust outlet that gas is entered atmosphere.

The purpose of this utility model realizes in such a way, air-introduced machine is sent into the foul smell of collecting in this equipment, earlier through not having the gas pipe in the entry that torrent are cut into than minute bubbles, after gas is washed through the first order, part NH3, H2S are separated by water-soluble, gas rising afterwards enters inert filler layer and the abundant haptoreaction of filling surface biomembrane, and inert filler layer biomembrane metabolic nutrition derives from gas and active filler layer leaching liquor; Gas enters that biological respinse harmful substance major part is removed in active filler layer and the filler afterwards; Gas rises to the spray washing layer afterwards, remaining pernicious gas is carried out last absorption, shower water is that inert filler has been carried nutrient through active filler layer dissolving part nutriment, and excessive solution flows under the influence of gravity into housing bottom, as first order washing water source; Because having guaranteed first order water level, the effect of overflow pipe can not increase system's design resistance loss.

Four segments combined biological deodorizing equipment compared with prior art, maximum characteristics are that two-stage washing and two sections absorption are concentrated in the same equipment, performance complement is avoided influencing each other simultaneously, at sewage disposal or mud/refuse disposal foul smell characteristics, efficiently, stablize, increase the service life, avoid filler owing to soda acidization lost efficacy.

Four segments combined biological deodorizing equipment can be used for each stage that sewage treatment plant, mud, rubbish and feces of livestock and poultry are disposed engineering, substitute existing biofilter, bio-trickling filter.

Description of drawings

With reference to Figure of description the utility model is done following detailed description.

Fig. 1 is four segments combined biological deodorizing equipment profiles.

Fig. 2 is the gas pipe schematic top plan view.

As shown in Figure 1, its primary structure is divided into parts such as housing 1, spray pump 2, gas pipe 3, inert filler layer 4, active filler layer 5, spray nozzle 6, floss hole 7, overflow pipe 8, blow-down pipe 9.

The specific embodiment

Of the present utility model four segments combined biological deodorizing equipment processing and fabricatings are simple and convenient, and processing and fabricating gets final product shown in the accompanying drawing to specifications.

Housing 1 adopts carbon steel inner lining glass fiber reinforced plastic material;

Spray pump 2 adopts general-purpose centrifugal pump;

Gas pipe 3 adopts the anticorrosion or stainless steel of carbon steel;

Inert filler layer 4 adopts multiaspect hollow ball filler;

Active filler layer 5 adopts the mud after compost or the mummification to mix with organic substances such as peat, haydite, wood chip, barks;

Spray nozzle 6 adopts the lawn irrigation nozzle;

Floss hole 7 adopts identical material with gas pipe;

Overflow pipe 8 adopts identical material with gas pipe;

Blow-down pipe 9 adopts identical material with gas pipe.

Four segments combined biological deodorizing equipment are not compared with prior art changing under the prerequisite of financial cost substantially, reduce floor space and operation stability, and Installation and Debugging are convenient, and therefore long service life has broad application prospects.

Except that the described technical characterictic of specification, be those skilled in the art's known technology.
