Abstract

The invention relates to the technical field of environmental protection, in particular to a tail gas purification device with anti-corrosion connecting pipes, including a tail gas purification tower, a smoke inlet pipe and a three-way liquid outlet pipe are fixedly installed on the tail gas purification tower, and the three-way outlet pipe A first waste liquid pipe and a second waste liquid pipe are fixedly installed on the liquid pipe, and a control valve is fixedly installed on the three-way liquid outlet pipe, and a liquid inlet pipe is fixedly installed on the first waste liquid pipe and the second waste liquid pipe. mouth, and the sealing structure with telescopic function is fixedly installed on the liquid inlet by buckle; the present invention connects two waste liquid pipes, the first waste liquid pipe and the second waste liquid pipe, by using the three-way liquid outlet pipe, and the two waste liquid pipes The latter can work at the same time or in rotation. When the rotation is performed, one can be used as a preparation when the liquid is discharged, so that the anti-corrosion layer can be repaired in the process of single-pipe preparation, and there is no need to stop work. Complete maintenance to ensure the efficiency of exhaust gas treatment.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a tail gas purification device with anti-corrosion connected pipes. Background technique [0002] Phosphoric acid is an important chemical raw material, a reactant and an intermediate product for the preparation of various reagents. The traditional production process of phosphoric acid consumes a lot of energy, so the total heat recovery heat method is often used to produce phosphoric acid. The main method is to burn yellow phosphorus in a combustion furnace. Phosphorus gas, and then use phosphorus pentoxide gas and water to produce sulfuric acid, this method can effectively utilize the heat of combustion. [0003] However, in the current phosphoric acid preparation process, acid waste gas is still easily generated, which must be purified by a purification tower before being discharged. Generally, a spray structure is used in the purification tower to spray wat...
