Problems solved by technology

[0003] Using water as the absorption liquid is based on the characteristics of large proportion of lead fume and insoluble in water. Using the principle of physical absorption, the purification rate of the water absorption method is related to the type and operation of the purification equipment. The lead dust is treated inside the treatment tower, and some lead dust After wetting, it sticks to the inner wall of the treatment tower. An observation window is installed on the surface of the treatment tower, so that lead dust sticks to the inner wall of the through window, which affects the observation inside the treatment tower.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Please refer to Figure 1-Figure 4 , a lead smelting tail gas treatment process, the process steps are as follows:

[0025] S1: the exhaust gas in the lead smelting equipment is collected in the heat exchange equipment through the conduit for heat exchange and cooling, so that the temperature of the exhaust gas is reduced;

[0026] S2: then the exhaust gas after the cooling treatment in S1 is introduced into the treatment tower of the tail gas treatment device for processing, and the inner wall cleaning structure provided in the tail gas treatment device is used to clean the lead dust adhered to the inner wall of the treatment tower, so that the lead The dust accelerates to flow into the set lead ash collection mechanism for collection;

[0027] S3: Send the tail gas treated in the tail gas treatment device into the detection device for detecti...

Abstract

The invention relates to the technical field of tail gas treatment, in particular to a lead smelting tail gas treatment process which comprises a treatment tower, an inner side wall cleaning structure, a lead ash collecting structure, a watering dust removal structure and an observation structure. The inner side wall cleaning structure is connected to the treatment tower and comprises a first gear, a second gear, a first motor, a first water pipe, a T-shaped rotating pipe, a first water inlet pipe, a first water tank and a first water pump, wherein the outer side face of the bottom of the treatment tower is connected with the top surface of the first water tank through a triangular frame; a first water pump is installed on the top of the first water tank, wherein an inlet of the first water pump communicates with the interior of the first water tank through a first water inlet pipe. The lead smelting tail gas treatment device provided by the invention has the advantages that lead dustaccumulated on the inner side wall of the round observation window on the observation structure is washed out and moved out, so that the observation window is not covered and can work for a long time.Operators can see through the internal condition of the treatment tower.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment, in particular to a lead smelting tail gas treatment process. Background technique [0002] The tail gas treatment process of lead smelting adopts the water absorption method, which is currently the simplest and most common method. [0003] Using water as the absorption liquid is based on the characteristics of large proportion of lead fume and insoluble in water. Using the principle of physical absorption, the purification rate of the water absorption method is related to the type and operation of the purification equipment. The lead dust is treated inside the treatment tower, and some lead dust After wetting, it sticks to the inner wall of the treatment tower, and an observation window is installed on the surface of the treatment tower, so that lead dust sticks to the inner wall of the through window, which affects the observation inside the treatment tower. Therefore, it is necessar...
