Catalytic combustion device self-circulation preheating system and method for organic waste gas VOCs treatment

Abstract

The invention discloses a catalytic combustion device self-circulation preheating system and method for organic waste gas VOCs treatment. The catalytic combustion device self-circulation preheating system comprises a catalytic combustion device and a circulation draught fan. The catalytic combustion device is internally provided with an electric heater, a catalyst, an organic waste gas air outletand an organic waste gas air inlet. One side of the catalytic combustion device is further provided with a circulation air inlet and a circulation air outlet. The circulation draught fan is connectedwith the circulation air inlet and the circulation air outlet through air homogenizing pipes. The self-circulation preheating method comprises the following steps that before organic waste gas VOCs enters the catalytic combustion device, the circulation draught fan is started, then the electric heater is started, the catalyst in the catalytic combustion device is preheated, and finally when the temperature of the catalyst reaches the preset temperature, the organic waste gas VOCs enters the catalytic combustion device to be subjected to catalytic combustion. According to the catalytic combustion device self-circulation preheating system and method, the structure is simple, usage is convenient, sufficient combustion of the organic waste gas VOCs can be guaranteed, and energy is saved.

Description

technical field [0001] The invention relates to a catalytic combustion device for the treatment of organic waste gas VOCs, in particular to a self-circulation preheating system and a method thereof for the catalytic combustion device for the treatment of organic waste gas VOCs. Background technique [0002] The catalytic temperature of organic waste gas VOCs must be > 250°C. Before entering the catalytic combustion device, the catalyst is preheated and heated. When the specified temperature is reached, the organic waste gas VOCs is sent to the catalytic combustion device to make it fully catalytic combustion. [0003] In the prior art, an electric heater is generally installed in the catalytic combustion device to heat the catalyst through the electric heater. However, during the heating process of the electric heater, it is difficult to specify the temperature requirements, and the heating is uneven, which leads to combustion. insufficient. [0004] In addition, the pow...
