Furnace chamber for smelting non-ferrous metals

Abstract

The invention belongs to the technical field of smelting furnaces, and particularly relates to a furnace chamber for smelting non-ferrous metals. The furnace chamber includes a furnace body, a gas conveying pipe, a pressurizing machine, a solenoid valve, an exhaust gas treatment module and a controller, the controller is used for controlling the power-on and power-off of the solenoid valve, the exhaust gas treatment module is located at the upper end of the furnace body and used for removing the acidoid in the exhaust gas, one end of the gas conveying pipe communicates with the upper end of the furnace body, and the gas conveying pipe is connected with the pressurizing machine and the solenoid valve in sequence; and the other end of the gas conveying pipe is led to the exhaust gas treatment module, the gas conveying pipe is used for inducing the exhaust gas in the furnace body to the exhaust gas treatment module, the pressurizing machine is used for pressurizing the exhaust gas in thegas conveying pipe, and the solenoid valve is used for opening and closing the gas conveying pipe intermittently. According to the furnace chamber, the exhaust gas and the lye have an adequate neutralization reaction by pounding the lye through an elastic corrugated plate, the acidic substances in the exhaust gas can be completely neutralized, and the fact that the environment is polluted due to the formation of acid rain caused by the fact that exhaust gas is exhausted to the atmosphere is avoided.

Description

technical field [0001] The invention belongs to the technical field of smelting furnaces, in particular to a furnace chamber for smelting nonferrous metals. Background technique [0002] The vast majority of modern ironmaking uses blast furnaces to smelt non-ferrous metals, and a few use direct reduction and electric furnace smelting metals. Blast furnace metal treatment is to reduce metal ore in blast furnace, melt and smelt pig iron, this method is easy to operate, low energy consumption, low cost, and can be mass-produced; but in the process of refining non-ferrous metals, a large amount of waste gas will be generated, these Exhaust gas contains a large amount of acidic substances, including various sulfides such as sulfur dioxide. If these exhaust gases are discharged into the atmosphere, it will easily form acid rain and cause environmental pollution. [0003] There are also some technical solutions for smelting furnaces in the prior art. For example, a Chinese patent ...

AI Technical Summary

Problems solved by technology

[0004] This technical solution can prevent pollutants from being discharged directly, and is equipped with a heat preservation chamber, which can effectively reduce heat dissipation, save energy and protect the environment; The acidic substances in the exhaust gas are fully mixed and neutralized with the lye, so that the acidic substances in the exhaust gas are not completely treated, and the exhaust gas will still form acid rain in the atmosphere and pollute the environment
