AI Technical Summary

Technical Problem

In existing technologies, the direct emission of waste gas from forging heating furnaces pollutes the air and harms human health. Furthermore, the cost of separate treatment is high, and it is difficult to effectively remove toxic and harmful gases.

Method used

Design a waste gas treatment mechanism for a forging heating furnace. The mechanism utilizes a serpentine tube to spray different solutions (such as water, sodium hydroxide, ethanol, and benzene) at multiple downward bends to dissolve toxic and harmful gases in the waste gas. Power is provided by a fan, and the solution is managed by an electromagnetic valve and a water suction box to ensure that the gas is discharged in compliance with standards.

Benefits of technology

It achieves simple and low-cost waste gas treatment, effectively dissolves and removes most toxic and harmful gases, ensures compliance with emission standards, and prevents solution vapor leakage.

Abstract

This utility model relates to the field of forging production waste gas treatment technology, specifically to a waste gas treatment mechanism for a forging heating furnace. It includes an exhaust port connected to the forging heating furnace, a fan connected to the exhaust port, and a serpentine pipe connected to the fan's outlet. The serpentine pipe contains several downward bends, each of which is sprayed with a solution to dissolve the waste gas. By using the serpentine pipe to treat the waste gas during its discharge process, the residence time of the waste gas within the pipe is increased due to its winding shape, resulting in better dissolution of harmful gases. Water effectively dissolves various sulfur oxides, sodium hydroxide effectively dissolves various nitrogen oxides, and ethanol dissolves carbon monoxide, among others. Therefore, it can effectively dissolve and remove most toxic and harmful gases, enabling the waste gas to meet emission standards. Furthermore, the process is simple and low-cost.
