Automatic collection method for cuprous chloride process tail gas

Abstract

The invention discloses an automatic collection method for cuprous chloride process tail gas. The method comprises the following steps: S1, carrying out primary treatment on the tail gas; s2, removing chlorine-containing tail gas; s3, recycling tail gas; a tail gas recovery device used in the cuprous chloride process tail gas automatic collection method comprises a collection pipe, a centrifugal barrel is rotationally connected into the collection pipe in a sealed mode, a plurality of discharging ports are formed in the side wall of the centrifugal barrel, and a plurality of discharging pipes matched with the discharging ports are embedded in the inner wall of the collection pipe. And a supporting plate is arranged in the collecting pipe. When the axial flow fan for extracting tail gas rotates, the magnetic fan blades periodically pass through the two spiral coils, in this way, current with the constantly changing magnitude can be introduced into the second spring, the second spring is made to stretch out and draw back, then under the current limiting effect of the one-way valve, heat exchange water is continuously output from the heat absorption pipe, and therefore tail gas heat is absorbed and recycled.

Description

technical field [0001] The invention relates to the technical field of cuprous chloride tail gas treatment, in particular to a method for automatically collecting tail gas from a cuprous chloride process. Background technique [0002] In industrial production, the preparation of cuprous chloride by dry method will continue to produce a large amount of copper-containing and chlorine-containing tail gas. At present, solid impurities and chlorine-containing tail gas in the tail gas are generally removed by absorption and filtration. [0003] However, in the dry preparation process, high-temperature heating is required, so the tail gas produced has a relatively high temperature, and the high-temperature tail gas is discharged directly, which not only enhances the greenhouse effect, but also does not recover and utilize the heat of the tail gas, which inevitably leads to energy waste. The purified exhaust gas often contains extremely small copper-containing dust. Accordingly, th...
