Description
Technical field
The utility model relates to deodorization technology field, be specifically related to a kind of biological deodorizing system.
Background technology
Biological filter process deodorization process is a kind of safe and reliable processing method, and odor removal efficient is greater than 90%.Its principle is that the foul smell that produces in sewage disposal process is concentrated and delivered to deodorization device of biological filter process after gathering system is collected, foul smell is by moistening, porous and the filtering layer being full of active microorganism, utilize microbial cell to the absorption of odorant, absorption and degradation function, the feature that the cell individual of microorganism is little, surface area is large, adsorptivity is strong, metabolic type is various, resolves into CO after being adsorbed by odorant

3etc. simple inorganic matter.
Biological deodorizing process is mainly carried out with three steps: (1) water-soluble infiltration; (2) bio-absorbable; (3) biological oxidation.
Water-soluble process of osmosis is the first step of biological deodorizing.Filter material surface is coated with water layer, and at superficial dissolution after the chemical substance in foul smell contacts with filtrate, and be aqueous phase from gas phase conversion, the bacterium be beneficial in filtrate further absorbs Sum decomposition.In addition, the porous of filtrate makes it have the specific area of super large, make gas, water two-phase has larger contact area, increase effectively the transmission diffusion rate of gas chemistry material in aqueous phase (through experiment test gained, its temporal effect produced is the good hundred times of Chemical cleaning).So water-soluble process of osmosis is a physical action process in fact, transmission diffusion at a high speed means that the concentration of foul smell can be down to extremely low level rapidly by filtrate.
Second step: the odor pollutant in the aqueous solution is by microorganism adsorption, absorption, and odor pollutant is transferred in microbial body from water;
3rd step is carried out the process of degradation of contaminant.Obligate bacterium in filtrate (the process bacterial classification obtained according to the type screening in smelly source) will be food with pollutant, be the nutriment of self contamination transform, the elements such as carbon, hydrogen, oxygen, nitrogen, sulphur are made to be converted into free state from the form of compound, enter the repeats itself process of microorganism, thus reach the object of degraded.Meanwhile, the microorganism such as obligate bacterium can realize again the reproductive process of self.When reaching balance as the pollution compound of food and the nutritional need of obligate bacterium, and the conditions such as moisture, temperature, soda acid degree all meet Institute of Micro-biology takes, the metabolism breeding of obligate bacterium will reach a stable balance, and final product is free of contamination carbon dioxide, water and salt.Thus pollutant is removed.Final purification air enters air.
And there are some defects in the biological deodorizing system that cement plant uses at present: absorb degradation effect not good, and then cause odor removal efficient low, dependability is poor, and practicality is not good.
Utility model content
For the deficiency that prior art exists, the utility model object is to provide a kind of biological deodorizing system, and structure is simple, long service life, and good deodorization effect is practical.
To achieve these goals, the utility model realizes by the following technical solutions: biological deodorizing system, comprise centrifugal blower, circulating pump, pre-wash pool and biofilter, centrifugal blower front end is connected with odor collection system by collection conduit, centrifugal blower rear end is connected with biofilter with pre-wash pool successively, described pre-wash pool and top, biofilter are provided with spray system, pre-wash pool is also connected by circulating pump with biofilter, be provided with biologic packing material in described biofilter, biologic packing material is supported by packing support and arranges.
As preferably, described biologic packing material adopts the special efficiently organic and inorganic mixed fillers of multiple grating, its permeability and structural stability good, there is the suitable environment of adsorption fouling thing and growth of microorganism, have operating cost low, safeguard the advantages such as simple.Biologic packing material is suitable for the waste gas of process 5 DEG C ~ 40 DEG C.Mixed fillers, based on volcanic rock, has good moisture retention and gas permeability, and carrier surface is hydrophily.
As preferably, described packing support is glass fiber reinforced grid-like panel.
As preferably, described pre-wash pool and the shell of biofilter are fiberglass sandwich plate shell.
As preferably, described top, biofilter is provided with air discharge ports up to standard.
As preferably, described biofilter is also connected with active carbon casing, adopts the suction-operated of active carbon by foul smell Molecular Adsorption remaining for biological treatment to reach the requirement of emission limit.Active carbon has more flourishing pore structure, and specific area is large, the various materials that energy binding molecule varies in size; Stable chemical nature, energy are acidproof, alkaline-resisting, applied range; Available multiple method regeneration, cuts operating costs.Charcoal absorption, mainly as emergency processing, can directly be discharged when foul smell after biological deodorizing can meet emission request restriction.
The beneficial effects of the utility model: structure is simple, long service life, good deodorization effect is practical, and the gas after its process can qualified discharge.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the utility model further.
With reference to Fig. 1, this detailed description of the invention is by the following technical solutions: biological deodorizing system, comprise centrifugal blower 1, circulating pump 2, pre-wash pool 3 and biofilter 4, centrifugal blower 1 front end is connected with odor collection system by collection conduit, centrifugal blower 1 rear end is connected with biofilter 4 with pre-wash pool 3 successively, described pre-wash pool 3 and top, biofilter 4 are provided with spray system 5, pre-wash pool 3 is also connected by circulating pump 2 with biofilter 4, be provided with biologic packing material 6 in described biofilter 4, biologic packing material 6 is supported by packing support 7 and arranges.
Pond, the biofilter body of this detailed description of the invention is through pretreatment unit and the air that have adjusted humidity enters into biological deodorization tank body, and microorganism will cause smelly contaminant degradation and become the compound of odorless wherein.
Biofilter is modular, and shell adopts the manufacture of fiberglass sandwich plate, corrosion-resistant, especially resistance to aliphatic acid corrosion, and tower body can be made to have enough strength and stiffness.The annex that filter tank configuration duct collar, pipe joint, packing support plate, filler, access hole, shower humidification device etc. are perfect.Top, biofilter adds the top cover with steam vent.
The packing support plate of biofilter adopts the glass fiber reinforced grid-like panel with good permeability, corrosion-resistant, and has enough rigidity, intensity.The outer surface ultraviolet radiation resisting in filter tank.Distribution of gas and drainage system is provided with bottom filter tank.Top, filter tank is provided with spray system, by automatic controlling system, carries out intermittent shower according to actual conditions, keeps necessarily moistening, for microorganism provides suitable working environment to make filler.Biological deodorizing device main equipment is greater than 10 years service life.
