Abstract

The utility model discloses a waste gas treatment device, which comprises a filter pipe. A filter device is arranged in the filter pipe, two ends of the filter pipe are respectively connected with a gas inlet pipe and a gas discharge pipe, and the gas inlet pipe and the gas discharge pipe are all conical pipes of which the opening cross sections gradually get smaller, wherein an opening of one end of the connection position at which the gas inlet pipe and the gas discharge pipe are respectively connected with the filter pipe is larger than an opening of the other end of the connection position. As employing the above technical scheme, compared with the prior art, the waste gas treatment device solves the technical problems that waste gas can not be treated completely and pollutes environment and the like in the prior art, and has the advantages of simple and effective structure, reabsorbing harmful gas in the waste, protecting environment and the like.

Description

A kind of emission-control equipment

Technical field

The utility model belongs to exhaust treatment system, particularly relates to a kind of emission-control equipment.

Background technology

Present some factories such as five metals, casting, paint, application factory etc., in producing spraying process, can produce a lot of pernicious gases, such as in the paint spray booth be will produce in the painting process paint collect and in indoor processing, and to paint in organic solvent (as toluene, dimethylbenzene etc.) ease mist then can't directly be collected, generally be adopt the high pressure air exhauster with it at high altitude discharge, though it is lower to contain the exhaust gas concentration of this kind solvent, the discharging of accumulating over a long period also can produce very big influence to environment, causes the pollution of environment.

Summary of the invention

The utility model has mainly solved in the prior art waste gas and can't handle not exclusively, and technical problems such as contaminated environment provide a kind of and simple in structurely effectively can absorb the pernicious gas in the waste gas once more, the emission-control equipment of protection environment.

The technical solution of the utility model is achieved in that a kind of emission-control equipment, it comprises screen pipe, in screen pipe, be provided with filter, two ends at screen pipe are connected with air inlet pipe and blast pipe respectively, air inlet pipe and blast pipe are opening section conical pipe from large to small, wherein air inlet pipe and blast pipe respectively with the opening of this end of screen pipe junction opening greater than separately an other end.

As preferably, described filter is the active carbon layer of nonwoven parcel.

Regularly replace the adsorbent in the filter for convenience,, on the tube wall of screen pipe, also be provided with the mouth that reloads, outside the mouth that reloads, be provided with lid as preferably.

Compared in the past, adopted the technical solution of the utility model, significantly reduced the pernicious gas in the waste gas, the waste gas harmfulness of discharge is reduced greatly, protected environment.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

The specific embodiment of the present utility model is as follows: as shown in Figure 1, according to a kind of emission-control equipment of the present utility model, it comprises columniform screen pipe 3, in screen pipe 3, be provided with filter, described filter is the active carbon layer of nonwoven parcel, the cross-sectional sizes of active carbon layer is identical with the inner tube diameter size of screen pipe 3, thus the pernicious gas more completely in the filtering exhaust.

Be connected with air inlet pipe 1 and blast pipe 2 respectively at the two ends of screen pipe 3, described air inlet pipe 1 and blast pipe 2 are opening section conical pipe from large to small, wherein air inlet pipe 1 and blast pipe 2 respectively with the opening of screen pipe 3 these ends of junction opening greater than separately an other end, be the opening of the opening of air inlet pipe 1 and screen pipe 3 these ends of junction greater than air inlet pipe 1 an other end, the opening of blast pipe 2 and screen pipe 3 these ends of junction is greater than the opening of blast pipe 2 other ends, the contact area of waste gas and filter can be increased like this, thereby the filter pernicious gas in the filtering exhaust more completely can be made.

If filter is long service time, then can adhere to a lot of solvents on the active carbon layer surface, form one deck mucous membrane, cause waste gas to discharge, in order to regularly replace the active carbon in the filter, on the tube wall of screen pipe 3, also be provided with the mouth 4 that reloads, outside the mouth 4 that reloads, be provided with lid 5, during replacing, can open lid 5, the active carbon that needs are changed takes out, with the active carbon that more renews.

Claims

1, a kind of emission-control equipment, it comprises screen pipe (3), in screen pipe (3), be provided with filter, be connected with air inlet pipe (1) and blast pipe (2) respectively at the two ends of screen pipe (3), it is characterized in that air inlet pipe (1) and blast pipe (2) are opening section conical pipe from large to small, wherein air inlet pipe (1) and blast pipe (2) respectively with the opening of this end of screen pipe (3) junction opening greater than separately an other end.

2, a kind of emission-control equipment according to claim 1 is characterized in that described filter is the active carbon layer of nonwoven parcel.

3, a kind of emission-control equipment according to claim 1 and 2 is characterized in that also being provided with reload mouthful (4) on the tube wall of screen pipe (3), be provided with lid (5) outside reload mouthful (4).
