Waste gas treatment device for metallurgy furnace

Abstract

The invention discloses a waste gas treatment device for a metallurgy furnace. The device of the invention comprises an electric furnace, a thermoelectric conversion device and a tail gas treatment device. A furnace lid is arranged below the electric furnace. The furnace lid is rotatably connected on the electric furnace. A hearth is arranged inside the electric furnace and is fixedly connected tothe electric furnace. The thermoelectric conversion device is arranged at the left side of the electric furnace and is fixedly connected to the electric furnace. The tail gas treatment device is arranged at the left side of the thermoelectric conversion device and is fixedly connected to the thermoelectric conversion device. The waste gas treatment device for a metallurgy furnace has a reasonablestructure and is equipped with the tail gas treatment device. Harmful substances such as sulfide, benzene, etc. are easy to generate during the metallurgical process, and sulfide and sulfate formed in the air directly harm the health of human body and growth of crops and corrode metal and building materials. With the arrangement of the tail gas treatment device, alkali lye and benzene solution therein can effectively absorb harmful substances such as sulfur molecules, etc. in tail gas.

Description

technical field [0001] The invention relates to a waste gas treatment device, in particular to a waste gas treatment device for a metallurgical electric furnace. Background technique [0002] The metallurgical industry is one of the oldest industries in human history. Since the industrial revolution in the 18th century, due to the rapid development of the iron and steel industry, it has caused serious smoke pollution, and the non-ferrous smelting industry has risen accordingly, resulting in pollution problems of heavy metals and sulfur dioxide. In the past 50 years, dozens of major public hazard incidents have occurred in industrially developed countries. Among the eight representative and world-famous public hazard incidents, four of them were directly perpetrated by the metallurgical industry. [0003] However, the various pollutions produced by the existing equipment in the metallurgical process are very serious. The small solid dust produced by metallurgy has seriously p...

Problems solved by technology

[0003] However, the various pollutions produced by the existing equipment in the metallurgical process are very serious. The small solid dust produced by metallurgy has seriously polluted the air and seriously affected the respiratory system of organisms. The sulfide produced is highly corrosive and harmful to buildings. It poses a huge threat to crops, and at the same time, a lot of heat is wasted in the metallurgical process
