High-temperature smoke cooling, metering and packaging integrated device and process method thereof

Abstract

The invention provides a high-temperature smoke cooling, metering and packaging integrated device. The high-temperature smoke cooling, metering and packaging integrated device comprises a smoke collecting device, a smoke cooling and conveying system, a packaging device, a single-barrel weighing device and a smoke conveying device. According to the high-temperature smoke cooling, metering and packaging integrated device, the temperature of high-temperature smoke can be directly reduced from 180 DEG C to 60 DEG C and is lower than the highest tolerance temperature of bagging, and the basic packaging condition is met; the problem of connection sealing between a discharging opening and a packaging barrel is solved, the problem of smoke flying is solved, and the environmental risk is eliminated; the problem that the weight of a single barrel cannot reach the export sales weight is solved; single-bag metering is achieved, material calculation is facilitated, and real-time adjustment is facilitated; transfer transportation of a small truck is omitted, the production cost is saved, and the post risk coefficient is reduced; and a smoke kneading machine is omitted, equipment is reduced, andpollution sources are reduced.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and in particular relates to an integrated device for cooling, metering and packaging of high-temperature smoke and dust and a process method thereof. Background technique [0002] In the process of copper smelting, a large amount of volatile impurities and small dust particles in the raw materials are entrained into the flue gas. After removing more than 95% of the dust in the flue gas by electrostatic precipitator, it enters the wet purification system to wash and purify the flue gas. Afterwards, the flue gas that meets the conditions for acid production is obtained for the production of sulfuric acid. A large amount of dust collected by ESP contains toxic and harmful impurities such as As, Pb, Zn, etc., which need to be handled carefully to prevent environmental pollution. [0003] At present, there are the following methods for dust collection by electric dust collector: [0004]...

AI Technical Summary

Problems solved by technology

Gas escaping pollutes the environment, acidic liquid and gas corrode and damage equipment, and the formation of acid in the humidification process itself is an exothermic chemical reaction, which further increases the damage progress of the kneader, resulting in high cost of use of the kneader

The damage of the equipment leads to the on-site leakage, causing environmental pollution and increasing the workload of maintenance.
