Description
Technical field
The utility model relates to a kind of gas treatment equipment, particularly gas need contact or contact and need to drench respectively with identical or different solid the device of choosing with different liquids, more particularly, the utility model relates to a kind of multilayer packed tower purifier of industrial plants waste gas, as the waste gas purification packed tower that contains multiple poisonous and harmful substance of water processing establishment discharging.The utility model belongs to the waste gas treatment equipment field.
Background technology
In industrial processes, sometimes need or produce the gas of some component complexity, include polytype poisonous and harmful substance in these gases, be mainly odorant, as: sulfide (hydrogen sulfide, low molecule mercaptan, thioether, methyl disulfide etc.) also includes VOC, as benzene series thing, phenolic compound etc., also contain ammonia, low molecule organic amine etc., pollute surrounding enviroment.For the processing or the purification of these gases, need different environment or medium, have only two or more tandem arrangements of employing usually, just can reach final processing intent.
For example; include sulfide, VOC etc. in the waste gas that waste water and sanitary sewage disposal facility produce; when handling this class waste gas; usually the method that is adopted mainly contains liquid scrubbing technology (as CN97211331), biofiltration technology (as CN97121666) and absorbing process (" oil gas field environmental protection "; 1999; 2,37).These existing waste gas purification technologies adopt the device form of packed tower mostly.In these packed towers, all be provided with the filler of single or multiple lift.Yet, because microorganism there are differences the metabolic activity of different poisonous and harmful substances in the biofiltration technology, make the microorganism phase that is distributing different in the filler, these microorganisms exist complicated correlation between mutually, often carry out phase mutual interference and restriction to different metabolism the time; Simultaneously, no matter be in the absorbing process adsorbent (as active carbon), or liquid scrubbing technology in chemical agent, absorption to material also all has selectivity with absorption, so, adopt the said apparatus form, its process for purifying generally all stresses certain constituents in the purifying exhaust air, can not remove other type harmful substance comprehensively.Even if adopted the multilayer filler,,, also can't reach the effect of comprehensive removal all kinds harmful substance because different packing layers all adopts with a kind of leacheate and drip washing mode though can be adapted to dissimilar components.
Be subjected to only to adopt a certain process for purifying due to the complexity of waste gas component and the limitation that single process for purifying had, be difficult to reach the purpose that complicated ingredient waste gas purifies fully usually.The flat 1-245834 of patent JP has proposed to adopt the solution countermeasure of a plurality of individual layer packed tower series connection forms in order to solve this class problem.Though this can address the above problem, make also simultaneously that the packed tower number increases, floor space expansion, plant construction and operating cost improves.
Summary of the invention
Structure, each layer that employing has a plurality of packing layers can load the packed tower that different fillers and each packing layer can adopt different process for purifying respectively, not only can address the above problem, can not bring simultaneously yet such as the packed tower number increase, floor space expansion, plant construction and the operating cost defective improving.But the filler that is used for exhaust-gas treatment needs liquid drip washing usually, and different fillers or different different leacheate and the drip washing modes of packing layer needs, adopts identical leacheate and drip washing mode can not obtain best treatment effect.
Realize different drip washing in order to solve different packing layers, the utility model provides a kind of simple in structure, the device that can handle respectively gas under varying environment or ambient condition, can handle the multilayer packed tower purifier of the respectively independent drip washing operation of multilayer filler of complex component waste gas.
The utility model device comprises tower body and Ta Nei annex, annex comprises packing layer, spray equipment, cleaning device, gas-liquid branch device etc. in the tower, wherein spray equipment is positioned at each packing layer top, and cleaning device is positioned at each packing layer bottom, and gas-liquid branch device is between adjacent two packing layers.Gas-liquid branch device comprises liquid collecting board, exhaust passage and exhaust passage overcover, the liquid collecting board connects with tower body sealing, the liquid collecting board is provided with the exhaust passage, the exhaust passage is the tubular conduit structure on the liquid collecting board, one end of exhaust passage communicates with the liquid collecting board, the other end exceeds the liquid collecting board, the top of exhaust passage is hidden by the exhaust passage overcover, the sectional area of overcover is more than or equal to the discharge area of exhaust passage, and gas is by passing through between exhaust passage and the overcover.The exhaust passage overcover can be supported by tower body, liquid collecting board or exhaust passage.For preventing to produce too much deposit on the liquid collecting board, the liquid collecting board adopts the mode that is obliquely installed, and cleaning device is arranged on top, the high side of inclination of liquid collecting board.
Tower body can be selected different shapes, structure and material as required with the Ta Nei annex, and packing layer can be selected one or more according to the difference of handling source of the gas.Air inlet, exhaust outlet, spray inlet are set on the tower body, clean inlet, leakage fluid dram, air inlet and exhaust outlet are arranged on the tower body two ends, the spray inlet is according to spray equipment position relative set, operated by rotary motion is on the tower body between the two-layer packing layer, cleaning inlet and leakage fluid dram all is provided with on the tower body of relevant position above the liquid collecting board, for reducing the liquid holdup on the liquid collecting board, cleaning inlet and leakage fluid dram can be tangent with the liquid collecting board, is separately positioned on the high side of liquid collecting board inclination and the low side that tilts.
The utility model device can be determined the number of plies as required, is generally 2～20 layers, can load identical or different filler, gas-liquid branch device is set between each packing layer realizes each packing layer independence drip washing.
Gas-liquid branch device can be designed to different structure as required, and its function receives the upper strata leacheate for collecting, and discharges outside the tower by leakage fluid dram, makes gas enter down one deck (following current and adverse current all can) continuously simultaneously.Specifically describe the concrete structure of the utility model apparatus structure and several gas-liquid branch device with reference to the accompanying drawings.
The utility model apparatus structure is simple, can realize the independent drip washing operation of different packing layers in a tower, and floor space is little, and is easy and simple to handle.The utility model device can be used for a kind of situation that need carry out gas reaction or processing at varying environment or medium, be specially adapted to the purified treatment of complicated component waste gas, for example the waste gas that contains compositions such as hydrogen sulfide, benzene, volatilization hydrocarbon of water processing establishment discharging.The utility model device can move the process for purifying by the absorption that filler carried out more than three kinds or three kinds such as granular activated carbon, porcelain ring and peat, biological washing and biofiltration simultaneously, thereby realizes the purification fully of above-mentioned complex component waste gas.Because different packing layers needs different leacheate and drip washing mode, so the utility model device is highly suitable for this process form.
