Description
Technical field
The utility model relates to waste gas recovering device field, specifically a kind of closed DMF organic solvent waste gas recycling device.
Background technology
Current environmental problem is day by day serious, and the environmental problem such as water pollution, haze happens occasionally, and country is to also more and more stricter to the management of discharging waste gas, but present a lot of waste gas phenomenons still happen occasionally, especially some synthetic leather enterprises.Because synthetic leather enterprise inevitably uses DMF (dimethyl formamide), dimethyl formamide is the extremely wide industrial chemicals of a kind of purposes, also be a kind of fine solvent of having many uses, DMF is used for the wet spinning silk of the synthetic fibers such as polyacrylonitrile fibre, the synthesis of polyurethane by synthetic leather enterprise.So the waste organic solvent gas containing DMF can be produced in leather making processes, once allow these waste gas directly discharge will cause serious air pollution, and waste organic solvent gas can carry out recovery and re-uses, not only can decreasing pollution, more can save cost, accomplish energy-conserving and environment-protective.Aly the waste organic solvent gas reclaimer of DMF efficiently can just seem very important to realizing this goal.
Utility model content
The utility model will solve above-mentioned prior art Problems existing, provides a kind of closed DMF organic solvent waste gas recycling device, solves the problem at present to not good, the inadequate environmental protection of the waste organic solvent gas recovering effect containing DMF.
The utility model solves the technical scheme that its technical problem adopts: this closed DMF organic solvent waste gas recycling device, comprise the first blower fan, first blower fan is connected to absorption tower, first blower fan and junction, absorption tower are provided with the adsorption layer of adsorbable fine particle, the spraying layer that some layers are ventilative is intervally distributed with from low to high in absorption tower, spray head is equipped with in the bottom of spraying layer, spray head is connected with the water pipe of outside, absorption tower, be provided with devil liquor recovery groove bottom absorption tower, devil liquor recovery groove is connected with waste liquid collecting box by pump.After arranging like this, when waste gas is drawn into absorption tower via the first blower fan, the fine particle thing in waste organic solvent gas absorbs by adsorption layer, reduces particle to the impact of waste gas recovery.When waste organic solvent gas is by absorption tower, spray head ejection water smoke in absorption tower, just rest in the globule after DMF organic solvent in waste organic solvent gas mixes with droplet, circulated sprinkling water continues to spray, waste organic solvent gas and droplet be further fully immixture in absorption tower, now waste organic solvent gas is just just recovered by the tiny globule containing the part of DMF, the globule that water smoke after the spray of absorption tower and DMF waste organic solvent gas are mixed to form again then gathers devil liquor recovery groove, collected in waste liquid collecting box by pump again and carry out focusing on again recycling again, energy-conserving and environment-protective.
Absorption tower top exit is connected with drying box, and the direction that in drying box, waste gas passes through is provided with condensate layer, and the front and back end of condensate layer is connected.Waste gas is large at the vapor content of itself behind absorption tower, and the condensate layer by blind shaped time, the steam in gas is met condensation and is formed the globule, plays dry effect, for subsequent purification is ready;
Further, condensate layer becomes shutter.The condensate layer of blind shaped can increase the contact area between condensate layer and waste gas further, strengthens the dry defrosting function of drying box.
Water pipe is provided with Pressure gauge.The process monitoring whole spray is convenient in manometric setting, to reach the maximized object of spraying effect under the pressure of specifying.
Drying box end is connected with collection box, and the direction that the inherent waste gas of collection box passes through is provided with photocatalysis membrana, and collection box inner top is provided with ultraviolet lamp.Photocatalysis membrana is under the irradiation of ultraviolet lamp, produce the free radical activity material with extremely strong oxidability, by the material that the further oxidation Decomposition of harmful substance such as the ammonia in waste gas, hydrogen sulfide, VOC class become carbon dioxide, water etc. nonpoisonous and tasteless, and this mode of oxidizing just can carry out at normal temperature and pressure, alleviate technical costs, make waste gas reach the standard that can directly discharge, improve clean-up effect further.
Further, collection box end is connected with chimney by the second blower fan.Purified gas is drawn in chimney by the second blower fan further, is directly discharged by chimney, accelerates the waste gas after emission purification, raises the efficiency.
The effect that the utility model is useful is: of the present utility model rational in infrastructure, compact, utilize the DMF organic solvent material in the water smoke seizure waste gas of spray, recycle again, concrete effect comprises following: 1. in the design can by different operating parameters, the more general waste gas recovery equipment of organic efficiency 2. power consumption lower 3. required by meeting effectively can process a large amount of waste gas 3. and allow operating temperature high, and the scope of application is large.
