Efficient and safe regenerative combustion VOCs purification system

Abstract

The invention discloses an efficient and safe regenerative combustion VOCs purification system. The efficient and safe regenerative combustion VOCs purification system comprises a base, wherein a shell is fixedly installed on the top surface of the base, and a control panel is fixedly installed on the obverse side of the shell. The inlet air flow and the outlet air flow are separated through a flow guide device, the inlet air flow and the outlet air flow cannot be mixed with each other, meanwhile, the flow guide device can transmit the heat of the outlet air flow to the inlet air flow, and thepreheating effect on the inlet air flow is improved. By means of the cooperation of the control panel, a control module, a driving device, a lifting limiting device, a locking device, a rotating device, a conveying device and a pushing device, a sector-shaped catalyst block is automatically replaced in a non-stop mode, and therefore the continuity of the volatile organic chemical treatment process is ensured, manual participation is not required in the sector-shaped catalyst block replacing process, the time and the labor are saved, the automation degree is high, and the practicability of theefficient and safe regenerative combustion VOCs purification system is improved.

Problems solved by technology

[0003] Existing organic waste gas catalytic combustion equipment is mainly composed of heat preservation shell, heat storage body, heat exchanger, integral catalyst, electric heating device, etc. Preheat and reach the catalytic combustion reaction temperature, then the organic waste gas mixed with fresh air is sprayed on the regenerator to preheat the mixed gas, and then the mixed gas is sprayed on the surface of the monolithic catalyst for catalytic combustion reaction to realize the The purpose of purifying organic waste gas, but during the catalytic process, carbon deposits will gradually form on the surface of the catalyst, which will cover the catalyst and cause the catalyst to be deactivated, resulting in the catalytic combustion process not being able to proceed normally. Disassemble and remove the carbon deposits on the surface of the monolithic catalyst by roasting, which will not only interrupt the treatment process of organic waste gas, and the continuity will be poor, but also the process of disassembling the monolithic catalyst is complicated, time-consuming and laborious, so it is urgent to design a An efficient and safe regenerative combustion VOCs purification system
