Abstract
The utility model relates to an environment-friendly exhaust device of a vacuum furnace. The device comprises a condenser, a vacuum pump and an activated carbon absorber, wherein one end of a first heat exchange pipeline of the condenser is communicated with an air outlet of the vacuum furnace, the other end of the first heat exchange pipeline is communicated with an air inlet of the vacuum pump, a second heat exchange pipeline of the condenser is connected with cooling water, and an air outlet of the vacuum pump is communicated with the activated carbon absorber. The device is suitable for the vacuum furnace, the cooling water is not polluted after used and can be recycled, the gas can be discharged according to standards in a real sense after being absorbed by the activated carbon, no pollution is generated during the whole gas discharge process, and the discharge is environment-friendly in a real sense.
Description
Technical field
The utility model relates to the technical field of industrial waste gas treatment device, refers to especially a kind of vacuum drying oven environment-protective exhaust device.
Background technology
In the preparation process of polyester filament, polyester raw material can be attached on the filament spinning component, so must often clean to remove polyester lumps attached thereto to filament spinning component.Usually adopt at present filament spinning component is placed in the vacuum drying oven, by the heating of vacuum drying oven, make the polyester lumps on the filament spinning component be gasificated into polyester gas.Outside at vacuum drying oven all is provided with exhaust apparatus usually, polyester gas in the vacuum drying oven is extracted out from the gas outlet of vacuum drying oven, but gas temperature from vacuum drying oven out is generally more than 300 ℃, can cause vavuum pump impaired, if and the gas in the vacuum drying oven is directly emptying, then can pollute air.So present its structure of employed exhaust apparatus is generally: the gas outlet of vacuum drying oven is connected with an end of a spray chamber by pipeline, and the other end of spray chamber is connected with vavuum pump by pipeline.Its operation principle is: by the suction of vavuum pump, polyester gas is drawn from the gas outlet of vacuum drying oven, polyester gas is subject to the spray of cooling water when passing through spray chamber and dissolves in the cooling water, thereby realizes the polyester gas cleaning.Its shortcoming is: the polyester granulate of catching a cold after condensing enters in the cooling water, so that this cooling water can not recycle, can only as wastewater treatment, form easily Re-pollution.
The utility model content
Technical problem to be solved in the utility model is: a kind of vacuum drying oven environment-protective exhaust device that can not produce waste water is provided.
For addressing the above problem, the technical solution adopted in the utility model is: the vacuum drying oven environment-protective exhaust device, comprise condenser, vavuum pump and active carbon adsorber, one end of the first heat exchanging pipe of described condenser is connected with the gas outlet of vacuum drying oven, the other end of the first heat exchanging pipe is connected with the air inlet of vavuum pump, the second heat exchanging pipe of condenser connects cooling water, and the gas outlet of vavuum pump is connected with active carbon adsorber.
The beneficial effects of the utility model are: above-mentioned vacuum drying oven environment-protective exhaust device, its cooling water can not polluted after use, can repeat recycling, and its gas is after charcoal absorption, can realize real qualified discharge, in whole exhaust process, pollution-free generation is real environment protection emission.
Description of drawings
Fig. 1 is principle schematic of the present utility model;
Among the figure: 1, condenser, the 11, first heat exchanging pipe, the 12, second heat exchanging pipe, 2, vavuum pump, 3, active carbon adsorber, 4, vacuum drying oven.
The specific embodiment
Below by specific embodiment the utility model vacuum drying oven environment-protective exhaust device is described in further detail.
As shown in Figure 1, the vacuum drying oven environment-protective exhaust device, comprise condenser 1, vavuum pump 2 and active carbon adsorber 3, one end of the first heat exchanging pipe 11 of described condenser 1 is connected with the gas outlet of vacuum drying oven 4, the other end of the first heat exchanging pipe 11 is connected with the air inlet of vavuum pump 2, the second heat exchanging pipe 12 of condenser 1 connects cooling water, and the gas outlet of vavuum pump 2 is connected with active carbon adsorber 3.
Operation principle of the present utility model is: by the suction of vavuum pump 2, polyester gas is drawn from the gas outlet of vacuum drying oven 4, during polyester gas process condenser 1, with cool off after the cooling water heat exchange in the second heat exchanging pipe 12 of condenser 1, gas temperature is reduced within the scope that vavuum pump 2 can bear, thereby can not make vavuum pump 2 impaired, following cooled gas moves in the active carbon adsorber 3 behind vavuum pump 2, after active carbon was with polyester granulate absorption, gas can directly be realized qualified discharge.Cooling water in the second heat exchanging pipe 12 of condenser 1 can still flow in the pond after heat exchange is finished and reuse.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
