Abstract
The utility model relates to an exhaust recovery unit comprising an air purifier, a gas cooler, an adsorption tank, a condenser, a vacuum pump and a storage tank, wherein the air purifier, the gas cooler, the adsorption tank, the condenser, the vacuum pump and the storage tank are connected in series in the above sequence through a pipeline; a fan is arranged between the gas cooler and the adsorption tank; and the top of the adsorption tank is also connected with a cooling water pipe which recools the inlet waste gas. After the cooled gas passes through the adsorption tank, the organic media in the waste gas are adsorbed after passing through granular activated carbon and purified and exhausted into the atmosphere, the adsorbed and concentrated organic media enter the condenser from the adsorption tank for condensation and separation under the action of the vacuum pump and then enter the storage tank, and the purpose of recycling is achieved. In the utility model, the action switching is completed by an automatic control system in the system operation process; and the exhaust recovery unit has the advantages of simple structure, stable performance, convenient operation, good purification effect for waste gas, high recovery of organic solvent, environmental protection and energy conservation.

The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of effectively device for recovering tail gas of purifying exhaust air.
The utility model is achieved through the following technical solutions:
A kind of device for recovering tail gas, comprise: air purifier, gas cooler, adsorption tanks, condenser, vavuum pump and basin, wherein, air purifier, gas cooler, adsorption tanks, condenser, vavuum pump and basin are pressed the said sequence serial connection by pipeline, be used to quicken the blower fan that waste gas is discharged and between gas cooler and adsorption tanks, also be provided with, also be connected at the top of adsorption tanks and be used for cooling water pipe that the waste gas that enters is cooled once more.
Aforesaid device for recovering tail gas is characterized in that described gas cooler is a finned type heat exchanger.
Aforesaid device for recovering tail gas is characterized in that described adsorption tanks are a plurality of, are set up in parallel.
The beneficial effects of the utility model are:
The utility model is in the application of certain company's gluing machine production line:
There is the volatilization of a large amount of organic solvent in the said firm in process of production, and along with rising steadily and the reinforcement of people's environmental consciousness of organic solvent price, the said firm needs a kind of device for recovering tail gas of instant effect, less investment.
The said firm produced in 24 hours continuously, and use 1320kg glue, this glue to contain glue (curing degree) 38% every day in the production process, organic solvent (ethyl acetate) 62%, need add ethyl acetate 400kg when in addition adding pigment again, in conjunction with using total solvent amount 1230kg every day, the about 5000m of capacity per hour

The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail:
Fig. 1 is the structural representation of the utility model one embodiment.
As shown in Figure 1: device for recovering tail gas, comprise: air purifier 1, gas cooler 2, adsorption tanks 4, condenser 5, vavuum pump 6 and basin 7, wherein, air purifier 1, gas cooler 2, adsorption tanks 4, condenser 5, vavuum pump 6 and basin 7 are pressed the said sequence serial connection by pipeline, be used to quicken the blower fan 3 that waste gas is discharged and between gas cooler 2 and adsorption tanks 4, also be provided with, also be connected at the top of adsorption tanks 4 and be used for cooling water pipe that the waste gas that enters is cooled once more.
The used gas cooler 2 of present embodiment is a finned type heat exchanger, and described adsorption tanks 4 are 3, are set up in parallel.
During use, workshop waste gas is extracted out by blower fan, at first pass through air purifier 1, carry out impurity interception, purify and cooling processing the service life of guaranteeing in follow-up adsorption system can not stop up, prolong adsorbent in adsorption tanks 4 the macromolecular particle impurity in the waste gas this moment;
The general temperature of process purified waste gas is still than higher; be about 80～120 ℃; needing to do cooling handles; because temperature is very big to the influence of adsorption effect, therefore add gas cooler 2, both a finned type heat exchanger in the back of air purifier 1; gas is lowered the temperature; gas after the cooling is sent into adsorption tanks 4 by blower fan 3 again, and the organic media in the waste gas is adsorbed after by granular activated carbon, enters atmosphere after the cooling water pipe of pure qi (oxygen) by adsorption tanks 4 tops cools once more.
Under the effect of vavuum pump 6, be adsorbed and the organic media that concentrates enters condenser 5 from adsorption tanks 4 and carries out condensation, separation, enter then in the storage tank 7, reach the purpose of recycling.
The main excessively flow medium of the utility model in running is the volatilization gas of organic solvent, under confined space, gather certain concentration, meet naked light and can produce explosion phenomenon, so the electric elements of whole device for recovering tail gas must be explosion-proof, explosive-proof grade Ex d II A T1.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
