Flue gas purification system used in continuous smelting process

Abstract

The invention relates to a flue gas purification system used in a continuous smelting process. The flue gas purification system comprises two supporting seats and a purification unit, the two supporting seats are symmetrically arranged, and the purification unit is arranged between the upper ends of the two supporting seats. The invention can solve the current problems that the just generated flue gas is not cooled, the metal smelting is carried out in a high-temperature environment, the temperature of the generated flue gas is very high, the flue gas is not cooled, and even if the flue gas is purified, the flue gas still causes thermal pollution to the environment due to the too high temperature of the flue gas; and the time for flue gas to pass through purification equipment is too short, the flue gas is difficult to thoroughly purify, chemicals for purifying harmful gas and harmful particles in the flue gas in the purification equipment are difficult to replace in time, so that the purification effect on the flue gas is severely reduced after the chemicals are used up, and the flue gas which is not purified is discharged into the air, and environmental pollution is caused.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a flue gas purification system used in a continuous smelting process. Background technique [0002] Due to the rapid development of society, the impact on the environment is also increasing. Therefore, environmental protection is the guarantee for human survival. One of the environmental pollution is the substances that pollute the environment during the metal smelting process. Smelting is a refining technology that uses methods such as roasting, smelting, electrolysis, and the use of chemicals to extract metals from ores and reduce the amount of metals contained in them. During the metal smelting process, many harmful gases will be produced, such as: carbon monoxide, sulfur dioxide, hydrogen sulfide, etc., and some harmful particles, such as: silicon If the gas and particles are directly discharged into the atmosphere without purification, it will cause serious pollution...

AI Technical Summary

Problems solved by technology

[0004] 1. When the existing flue gas purification equipment purifies the flue gas produced by metal smelting, there is no cooling process for the newly generated flue gas, and the metal smelting is carried out in a high temperature environment, and the temperature of the flue gas generated is also Very high, if the flue gas is not cooled, even after the flue gas is purified, it will still cause thermal pollution to the environment due to its high temperature;

[0005] 2. When the existing flue gas purification equipment purifies the flue gas produced by metal smelting, the time for the flue gas to pass through the purification equipment is too short to be completely purified, and the purification equipment is used to purify harmful gases and harmful particles in the flue gas It is difficult to replace the chemicals in time, so that the purification effect of the flue gas will be seriously reduced after the chemicals are exhausted, and the unpurified flue gas will be discharged into the air, causing environmental pollution
