Abstract
The utility model relates to a waste gas purification and deodorization biological filtering-absorbing compound tower, which is composed of a liquid collecting section in a shell body, an air inlet pipe, an air distributor, a liquid distributor, etc. The utility model is characterized in that a process and filtration section for fixing and suspending two biological membrane filler layers is arranged under the liquid distributor, and an adsorption treatment section for agglomerate adsorbent is arranged on the upper part of the liquid distributor. The utility model can be widely used for purifying and deodorizing malodorant exhaust gas containing H< 2 >S. The utility model has the characteristics of high efficiency and favorable exhaust quality.
Description
The utility model relates to the biological filtration-adsorption combination tower of a kind of waste gas purification and deodorization.It belongs to the environmental project device for purifying gas.
Adopt traditional absorption method that waste gas purification and deodorization are had effect preferably, but because adsorbent cost costliness, regeneration is complicated, uses not have popularity.The biological deodorization method that developed recently gets up, have efficient height, reduced investment, the characteristics that operating cost is low, but this biofiltration device is because the biofilm packing that adopts all is fixing filler, amount of liquid is restricted between the gas liquid ratio, and when containing S, Cl exhaust-gas treatment, discharge opeing pH value is low, have acid to generate, the accumulation of acid has serious corrosiveness to equipment.
The purpose of this utility model is to provide the biological filtration-adsorption combination tower of a kind of waste gas purification and deodorization.This combination tower not only has the high characteristics of waste gas deodorization efficiency, and can improve the discharge opeing pH value of tower effectively, has solved because of acid accumulation and has caused the equipment corrosion problem.
In order to achieve the above object, the utility model is realized by following proposal.Under the liquid distribution trough (3) in the tower body (1) of combination tower, biofilm packing layer (4) is set constitutes waste gas biofiltration processing section, on the liquid distribution trough (3), adsorbent layer (2) is set constitutes waste gas adsorption treatment section.
Be the biodegradation efficient of raising exhaust-gas treatment and the adsorption efficiency of adsorbent, the lower floor of above-mentioned biofilm packing layer (4) is for to constitute fixedly packing layer by packing support plate spare and compressing member, on fixing packing layer, form by two-layer above supporting plate, place the floating filler layer of the biofilm packing that can fluctuate on every layer of support plate; Above-mentioned adsorption section (2) is that the blocks adsorbent by supporting member, compressing member and multilayer louvered is constituted.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 uses louvered adsorbent schematic diagram for the utility model adsorption section.
Fig. 3 is louvered adsorbent filling schematic diagram.
By Fig. 1 finding, in combination tower tower body (1), be provided with two-stage liquid distributor (3), the following of it is the fillter section (4) of biofilm packing successively, gas distributor (5), air inlet pipe (6), liquid collecting section (7) and discharging tube (8), biofilm packing section (4) branch upper strata again are the floating filler layer, and lower floor is fixing packing layer, on liquid distribution trough (3), be adsorption section (2), the gas collection section (9) of adsorbent successively.The utility model realizes that the process of waste gas purification and deodorization is: the spray liquid that contains organism is sprayed onto packing layer equably by liquid distribution trough, organism forms biomembrane on filler, and waste gas is entered in the tower by the air inlet pipe (6) of tower bottom, contact with biomembrane by packing layer (4) equably by gas pipe (5), formed gas-liquid two-phase and fully contacted, odorant is removed by gas phase → liquid film → biomembrane.Uprising gas by after the processing of biofiltration section is able to further purification by adsorption layer again, at last by outlet emptying.Spray liquid is collected in liquid collecting section (7), and it is outer and can be recycled to discharge tower by discharging tube (8) at last.
The utility model is compared with existing clarifier, and its advantage is: purify the deodorization efficiency height 1..Because the utility model adopts fixedly packing layer and floating stuffing layer, help improving packing layer degradation of contaminant unit volume matrix utilization rate, so purification efficiency can reach more than 98%.2. can effectively control acid accumulation, prolong service life of equipment.Because earth material section is provided with fixedly packing layer and floating stuffing layer, can make microorganism on the floating stuffing layer, the biomembrane that the growth of depending on is promptly arranged, suspension growth system in liquid phase environment is arranged again, and owing to improved intrasystem liquid holdup, fixedly packing layer has the efficient degradation ability to odorant in addition, therefore under the efficient clean-up effect and under the cushioning effect of big liquid holdup, can control elemental sulfur or sulfuric acid conversion.The utility model can be realized H
2The clearance of S reaches more than 90%, and pH is 6.0～6.2.3. purifying exhaust gas quality height.Can satisfy Industrial-Enterprises in China design sanitary standard (TJ36-79) after biofilm filtration section of the present utility model purifies foul gas, owing to be provided with adsorption layer, make gas be able to further advanced treating again, therefore discharge the gaseous mass height, can reach zero-emission.
Claims (2)
1. the biological filtration-adsorption combination tower of waste gas purification and deodorization, in tower body (1), mainly be provided with discharging tube (8), air inlet pipe (6), gas pipe (5), liquid distribution trough (3), it is characterized in that: under liquid distribution trough (3), biofilm packing layer (4) is set constitutes waste gas biofiltration processing section, on liquid distribution trough (3), be provided with adsorbent layer (2) and constitute waste gas adsorption treatment section.
2. press the biological filtration-adsorption combination tower of said waste gas purification of claim 1 and deodorization, it is characterized in that: said biofilm packing layer, its lower floor is for to constitute fixedly packing layer by packing support plate spare and filler compressing member, on fixed bed, be by the two-layer above supporting plate and the floating filler layer of the biofilm packing that placement can fluctuate on every layer of support plate; Adsorption section is that the blocks adsorbent by adsorbent supporting member and compressing member and multilayer louvered is constituted.
