Description
Technical field
The invention belongs to environmental protection, exhaust-gas treatment field, be specifically related to one and utilize physics, chemistry and biological deodorizing principle, adopt filter type to eliminate the design of the deodorization brick of foul gas and corresponding combination unit design.
Background technology
Along with the enhancing of China's national power, the raising of living standards of the people, increasing people starts to pay close attention to human settlement, and stench produces intense stimulus to the sense of smell of people, makes the thing improvement of odor pollution being become to public concern.In daily life, foul gas is mainly derived from the places such as municipal sewage plant, refuse landfill, livestock and poultry farm.As one of the public hazards of environment, stench, except causing the offending sensations such as the psychology detest of people, also can cause the discomfort on health, as felt sick, headache, poor appetite, sense of smell imbalance, insomnia, even emotional instability etc.Therefore, also all the more deep to the research of deodorization technology.
The composition of foul gas is more, and foul gas kind known at present has up to ten thousand kinds, different by the chemical constituent of gas, can be divided into 5 classes: one is the compound of sulfur-bearing, as H
2s, SO
2, thio-alcohol, thioether class; Two is containing nitrogen compound, as amine, acid amides, indoles; Three is halogen and derivative, as chlorine, halogenated hydrocarbons; Four is hydro carbons, as alkane, alkene, alkynes, aromatic hydrocarbon; Five is oxygen-bearing organic matters, as alcohol, phenol, aldehyde, ketone, organic acid etc.Through gas chromatographic detection, the main component of most foul gas is ammonia (NH
3) and hydrogen sulfide (H
2s).
At present, the method for process foul gas has three major types, i.e. Physical (sheltering neutralization, dilution diffusion, absorption), chemical method (chemical washing, oxidation, burning, absorption), bioanalysis (filtration, absorption, compost etc.).
Physical masking can eliminate stench impact as early as possible, and flexibility is large, and expense is low, but odor pollutant is not removed, and deodorizing rate is generally less than 50%, but Low investment.Dilution method expense is low, but is subject to the impact of meteorological condition, and odorant still exists.The advantage of physical adsorption method is technical maturity, can process multi-component foul gas, simultaneously recyclable utility, purification efficiency is about 95%, shortcoming be absorbent costly, to pending foul gas require higher, the preliminary clearning of General Requirements gas, otherwise adsorbent easily blocks.Physical adsorption method is suitable for processing and is applicable to process atm number, low concentration, the high process purifying the foul gas required.
Chemical combustion method purification efficiency is high, and odorant is decomposed by exhaustive oxidation, but equipment is perishable, consume fuel, and invest high, processing cost is high, easily forms secondary pollution; Oxidizing process purification efficiency is high, but needs oxidant, and disposal cost is high; The advantage of chemical absorption method is the organic odor gas that can process low concentration macromolecule, and purification efficiency is generally 60% ~ 80%, and shortcoming there is secondary pollution, and pollutant only transfers to liquid phase by gas phase.Chemical absorption method is suitable for processing aliphatic acid, ammonia and other foul smell soluble in water.
The advantage of biologic deodorization method is that purification efficiency is higher, and deodorization device is simple, and processing cost is cheap, and investment operating cost is low, and non-secondary pollution, manageability, is applicable to the process of the foul gas of middle low concentration.
By Physical, chemical method and bioanalysis combine less for the process report of foul gas.And relevant device complex structure, non-modular designs, construction is got up very inconvenient, can not need change associated component and filler according to actual treatment.
Summary of the invention
An object of the present invention is to provide a kind of filtering type deodorization brick, packing layer, waste and old iron wire layer and matrix soil layer are filled in wire netting shell successively, three layers isometric, but layout straggly when arranging, middle waste and old iron wire layer is that one end is protruded, the state that the other end is recessed, and the same side end of packing layer and matrix soil layer is at same vertical plane.Such structure is convenient to the splicing between filtering type deodorization brick.
The material of described packing layer is the natural porous stone material of microbe inoculation, can adsorb amine substance and degrade.
Waste and old iron wire layer can rapidly and H
2s gas reaction, the salt of generation can be absorbed by vegetation as the nutrient of matrix soil layer.
Described matrix soil layer can be contour with packing layer, also can lower than packing layer.There is vegetation, the effect that existing greening is attractive in appearance lower than the matrix soil layer of packing layer is planted, also have the function purified air.
Described matrix soil layer is formulated by farm manure and soil, rice husk, and concrete ratio is not restricted.Foul gas is adsorbed by matrix soil layer on the one hand; On the other hand, the microorganism in matrix soil layer can be degraded odorant, the material after degraded to be absorbed by vegetation as the nutrient of vegetation or odorant directly by vegetation root absorption.
Another object of the present invention is to provide a kind of combination unit of filtering type deodorization brick, interted by the protruding end of the female end of the filtering type deodorization brick filtering type deodorization brick identical with another block and connect, successively be installed in bracing members skeleton, bracing members skeleton is as body of wall and ceiling basis, top is spliced by matrix soil layer and the contour filtering type deodorization brick of packing layer, and flank wall is spliced by the filtering type deodorization brick of matrix soil layer lower than packing layer.
Described bracing members skeleton top is provided with spray water supply system, for the pouring of vegetation.
Described spray water supply system is provided with rotary spray head.
Be provided with drainage system bottom described bracing members skeleton, and be provided with water pump.The water that leaching gets off thus passage is discharged, and enters in spray system, re-use after collection by water pump.This device does not have waste water to discharge substantially, due to reasons such as evaporations, needs to supplement fresh water in time.
Beneficial effect of the present invention is:
1. traditional large area engineering construction method has been broken in modular deodorization brick design, and waste gas needs that can be different according to process, carry out the structural combination of various engineering, the feature for stench carries out the change of corresponding filler composition.Design and construct convenient and swift, foul gas process flexibility of practical application in engineering is improved greatly.
2. technically, physics, chemistry and biological method are organically combined in the design concept of deodorization brick, are different from the conventional arts such as biofilter, the requirement of removing foul gas fast can be reached.Make use of quick adsorption, the principle of absorption of physics, chemistry, the metabolism of microorganism, and plant utilizes the nutrition of odorant and catabolite thereof to grow, and has carried out quite effectively tackling to foul gas.
3. the use of deodorization brick, not only eliminates foul gas, and by appearance design, cultivation of plants, the deodorizing wall set up has the function of beautifying the environment.Under certain service condition, vegetation also can select remunerative crop.
4. the present invention can simplify detail design greatly, shortens the engineering time, more flexible compared with conventional method, convenient, fast.Device is simple, and operating cost is cheap, and maintenance management is convenient.Running non-secondary pollution, meets the ecological process requirement advocated energetically at present completely.
