Energy-saving waste gas treatment device

Abstract

The invention discloses an energy-saving waste gas treatment device. The device comprises a furnace end, a furnace hearth, a turbulent flow ring, a combustor and a tail gas inlet. The combustor is located at the front end of the furnace end and provided with a primary air inlet. By forming the tail gas inlet in the side wall of the front end of the furnace end, forming secondary air inlets in thetwo sides of the combustor, paving heat accumulating parts on the inner wall of a burning furnace and arranging airflow disturbance distribution walls and an airflow disturbance retainer ring, the burning furnace is divided into a plurality of spaces. Through the above multiple improvements, the two-airflow mixing degree is increased, and the fuel gas consumption is reduced; and meanwhile, the processing capacity of the whole burning furnace is improved.

Description

technical field [0001] The invention relates to a waste gas treatment device, in particular to an energy-saving waste gas treatment device. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may constitute prior art. During the process of realizing the present invention, the inventors have found at least the following problems in the prior art. [0003] The tail gas incinerator is an important equipment in the waste gas treatment process, which is mainly used to incinerate the tail gas after the process purification and discharge it into the atmosphere. Traditional tail gas burners, such as figure 1 As shown, the burner 4 is located at the front end of the burner head, the exhaust gas inlet is close to the boundary port 5, and the primary air inlet is set on the side of the burner 4, which supplies air to the burner 4 and mixes with the exhaust gas, and passes through the turbulent ring s...

AI Technical Summary

Problems solved by technology

[0007] 2. Failure to reach production capacity

But the acid gas volume exceeds 900Nm 3 When / h, the exhaust chimney will emit smoke. It feels that the front-end recovery device cannot handle it. In fact, the exhaust gas is burned and cannot be completely burned. 2 S causes smoke and incomplete combustion of exhaust gas

[0008] 3. Compared with the small burning furnace, it is much worse in terms of burning efficiency and fuel consumption
