Abstract

The invention discloses a recovering and purifying device for industrial exhaust gas, belonging to the field of exhaust-gas treatment. The recovering and purifying device for industrial exhaust gas mainly comprises a first filtering tower, a second filtering tower and a blower installed at an exhaust gas inlet in the bottom of the first filtering tower, wherein the first filtering tower and the second filtering tower is connected via a gas conveying pipe; the bottom end of the first filtering tower is provided with a liquid collection tank; two shower pipes and two filters are arranged in the first filtering tower, and PP filter cotton is arranged above the upper filter; an active carbon filter layer is arranged in the second filtering tower; and the top end of the second filtering tower is an exhaust pipe which the bottom end of the second filtering tower is a liquid collection tank. The recovering and purifying device provided by the invention has the advantages that activity of gas molecules and the adsorption effect of the active carbon filter layer are improved; exhaust gas purifying effect is substantially improved; and finally treat gas can be conveniently discharged into air or recycled via the exhaust pipe.

Description

An industrial waste gas recovery and purification device

technical field

The invention relates to waste gas treatment equipment, in particular to an industrial waste gas recovery and purification device.

Background technique

Oil processing usually has a heating process. The low temperature needs to be more than 100 degrees, and the high temperature can even reach more than several hundred degrees. During the oil production process, a large amount of waste gas will inevitably be generated. Since there are many substances harmful to the environment in the waste gas, they are directly discharged It will cause air pollution, so enterprises need to strictly deal with production waste gas, and only when environmental protection requirements are met can they be discharged.

Contents of the invention

The technical problem mainly solved by the present invention is to provide an industrial waste gas recovery and purification device, which is mainly used to solve the above problems.

The present invention solves technical problem and adopts following technical scheme:

An industrial waste gas recovery and purification device is provided, which mainly includes a first filter tower, a second filter tower, a blower installed at the inlet of the waste gas at the bottom of the first filter tower, and a filter between the first filter tower and the second filter tower. It is connected through a gas transmission pipe. The bottom of the first filter tower is provided with a liquid collection tank. There are two spray pipes and two filters in the tower body. A PP filter cotton is arranged above the uppermost filter. The second filter tower is provided with an active carbon filter layer, the top is an exhaust pipe, and the bottom of the second filter tower is provided with a liquid collection tank. A group of heating tubes are vertically installed in the top position of the gas delivery tube. The filter is formed from a non-woven fiber mass that is machined or formed into a filter substrate.

Preferably, the spray pipe is a liquid pipe with a porous bottom.

Compared with the prior art, the present invention has the beneficial effects: through the connection of two filter towers, the first filter tower spray + filter can effectively remove metal debris and large impurities in the exhaust gas, and effectively remove water through PP, It is passed into the second filter tower through the gas transmission pipe. At the same time, the temperature of the gas entering the second filter tower is significantly increased because of the heating tube in the gas filter tube, which increases the activity of gas molecules and the adsorption effect of the activated carbon filter layer. To improve the exhaust gas purification effect, the final treated gas can be easily discharged into the air or recycled through the exhaust pipe.
