Description

Technical Field

[0001] This utility model relates to the field of catalytic combustion devices for organic waste gas, specifically a safe and efficient catalytic combustion device for organic waste gas. Background Technology

[0002] The catalytic combustion device for organic waste gas is used to control the catalytic combustion of organic waste gas. Catalytic combustion of organic waste gas is a highly efficient method for treating volatile organic compounds (VOCs). The organic waste gas is first preheated to 200-400℃ through a heat exchanger. This step helps to increase the temperature of the waste gas, making it easier for it to come into contact with the catalyst and react.

[0003] For example, the authorized patent with publication number CN216047765U (High-efficiency catalytic combustion device for organic waste gas) is characterized by comprising a pre-filter box, a main air duct, a desorption system air duct, an activated carbon box, a main exhaust fan, a desorption system fan, a catalytic combustion device, a tail gas emission regulating valve for the catalytic combustion device, a mixed-flow replenishment and cooling device, and a control system. This utility model describes a high-efficiency catalytic combustion device for organic waste gas, which belongs to the category of waste gas treatment devices. The activated carbon has a long service life and is internally equipped with a flow equalization mesh plate and a flow straightening grid, allowing for thorough mixing of hot and cold gases within the mixed-flow box. The temperature sensor detects the temperature of the hot air entering the activated carbon box more accurately and stably. Each activated carbon box is equipped with a temperature sensor and a water spray fire extinguishing device to prevent combustion due to excessive temperature. The catalytic combustion device body is equipped with explosion relief plates, providing an outlet for the explosive gas flow in the event of an internal gas explosion, preventing it from entering the activated carbon box and making it safer and more practical.
