Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-3, an exhaust pipe for a waste gas treatment device comprises a housing 5, the housing 5 is cylindrical, a cooling liquid 15 is filled in the housing 5, the cooling liquid 15 can be water, an air inlet pipe 10 is communicated with the middle position of one end of the housing 5, reinforcing ribs 9 are fixedly connected with both sides of the air inlet pipe 10, the reinforcing ribs 9 are fixedly connected with the housing 5, a connecting flange 11 is fixedly connected with one end of the air inlet pipe 10, the other end of the housing 5 is communicated with a smoke outlet pipe 1, a bent pipe 6 is communicated with the air inlet pipe 10, one end of the bent pipe 6 is communicated with an elbow 4, the lower end of the elbow 4 is perpendicular to the liquid level of the cooling liquid 15, waste gas enters from the air inlet pipe 10, primary cooling is performed on the waste gas through the elbow 6, then the waste gas is sprayed out from the elbow 4 and contacts with the cooling liquid 15, so that the, meanwhile, the cooling liquid can absorb the particles in the waste gas.
