Operation principle of the present utility model is: the waste gas between the exhaust fan inhalation vehicle after the cooler preliminary treatment, enters in the absorber and adsorbs after filtration; When absorption when saturated, close intake valve and the air bleeding valve of absorber, open steam valve and carry out desorption, the vapour-liquid that desorption gets off enters condenser condenses through liquid valve, condensed mixed solution enters the layering groove and carries out gravitational separation, the organic solvent on upper strata enters storage tank and reclaims, and the waste water of lower floor enters collects the pond collection;
The waste water of collecting in the pond stirs through agitator, in this process, utilize the pH value of the medicament control waste water in the alkali bucket, water pump is sent the waste water in the agitator into evaporimeter and is evaporated afterwards, the thermal source of evaporimeter is provided by described steam boiler, is called primary steam, and above-mentioned waste water heating evaporation in evaporimeter forms indirect steam, indirect steam again enters and carries out desorption in the absorber, afterwards condensation, the waste water of generation enters again evaporimeter and recycles, and waste water does not efflux.
The beneficial effects of the utility model are: the utility model can be effectively with the waste gas recycling that produces in the workshop, reduction is to operating personnel's Health cost, utilize simultaneously evaporimeter that the waste water that condensation produces is evaporated to indirect steam, so that waste water is recycling all the time, reach the purpose that waste water does not efflux contaminated environment, simultaneously the organic matter in the waste water is reclaimed, can effectively reduce production costs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, the organic exhaust gas adsorption retracting device of non-wastewater discharge described in the utility model, press the flow direction of waste gas, comprise successively exhaust fan 1, filtration cooler 2, four absorbers 3, condenser 4, layering groove 5 and storage tanks 6 of adopting pipeline to connect, be provided with intake valve 11 between described filtration cooler and the absorber, pipeline between absorber and the condenser is provided with liquid valve 13, and absorber is provided with clean gas delivery pipe and air bleeding valve 12.This part-structure and existing adsorbing recovering device for waste gas are similar.
Improvement part of the present utility model is: described retracting device also comprises collection pond 7, waste water agitator 8, water pump 9 and the evaporimeter 10 that adopts pipeline to connect successively, collecting the pond also connects by the wastewater outlet of pipeline and described layering groove, the steam (vapor) outlet of evaporimeter is connected by pipeline and described absorber, forms the waste water recycling pipeline of a circulation; Described waste water agitator is connected with alkali bucket 16 by pipeline, and the thermal source entrance of described evaporimeter is connected by pipeline and steam boiler 17.Between evaporimeter and the absorber, and and steam boiler between pipeline on be respectively equipped with steam valve 14; Between described waste water agitator and the alkali bucket, and and water pump between pipeline be provided with valve 15; Pipeline between water pump and the evaporimeter is provided with valve.
The waste organic solvent gas that the workshop produces is in process of production collected through pipeline, pump to filtering cooler by exhaust fan, after filtration, after the cooling preliminary treatment, distribute by the tail gas flapper valve, corresponding each absorber that enters adsorbs, and adsorption time is controlled by PLC; When absorption when saturated, close the inlet and outlet valve, open steam valve, carry out desorption (utilizing high-temperature steam that the organic matter that adsorbs in the sorbing material is parsed).Vapour-liquid after the parsing enters condenser by liquid valve and carries out condensation; Condensing does not enter exhaust fan by gas-liquid separator and again adsorbs, mixed solution then enters the layering groove and carries out gravitational separation, (this pond is preferably in below ground to layering waste water out through collecting the pond collection, the waste water of being convenient to the layering groove flows automatically to this pond), establish one group of fluid level controller in the pond and show liquid level.The waste water of collecting in the pond is evacuated to agitator, and to the control that neutralizes of the pH value of the waste water in the agitator, the medicament of neutralization usefulness is by alkali bucket inflow agitator by the pH value controller.The pH value of waste water reaches to be squeezed into evaporimeter by water pump after the predetermined value and evaporates, and the liquid level of evaporimeter has one group of fluid level controller that water level is controlled in the normal range (NR).The thermal source of evaporimeter is supplied with by the steam boiler of factory, is called primary steam here, and evaporimeter is called indirect steam with the rear steam that produces of waste water heating.The pressure of the indirect steam that evaporimeter produces is sent to switch board by pressure transmitter, at the primary steam pipeline one group of proportioning valve is housed, by instrument the primary steam flow of evaporimeter is controlled, guaranteed to produce balanced indirect steam and be used for organic matter in the desorption adsorption tank.The waste water that produces during desorption is back to again in the wastewater disposal basin, and iterative cycles uses, and reaches the purpose that waste water does not efflux.
Layering solvent out then enters storage tank, quantitatively pumps to user's solvent storage tank.Each valve of complete equipment is carried out the control by switch board PLC, and the adsorption and desorption time is adjusted according to shop Planning by touch-screen by the user.
Have a large amount of heats can heat exchange from condenser in the process of desorption, these heats directly distribute by cooling tower can cause energy waste; The steam that desorption is got off is sent into first heat exchanger before entering condenser, and cold water enters behind the heat exchanger and the steam exchange.Concrete way is: make a water tank near the equipment, a water circulating pump is set up in the water tank outlet, pipeline and heat exchanger series connection, when carrying out desorption, the heat exchanger inlet temperature surpasses 50 and starts water circulating pump when spending, and the water of water tank is heated, and the hot water after the heating is used for the workshop.
The equal buyable of above-mentioned all devices obtains.
