External gas removing type heat-storage incinerator

Abstract

The invention relates to an external gas removing type heat-storage incinerator which comprises a heat-storage incinerator, an exhaust gas main pipeline, a windmill, an exhaust gas inlet valve bank, a leading control valve bank, an external gas blast pipeline and an external gas control valve, wherein the exhaust gas main pipeline is connected with a ventilating pipeline of the heat-storage incinerator, the exhaust gas inlet valve bank and the leading control valve bank are arranged on the exhaust gas pipeline so as to control and switch the pipeline to control the flow direction of the exhaust gas in the pipeline, the tail end of the exhaust gas main pipeline is provided with the windmill to form wind pressure to suck the gas in the pipeline, one end of the external gas blast pipeline is connected with the exhaust gas main pipeline to supply gas into the exhaust gas main pipeline and a heat-storage bed, the external gas control valve is arranged on the external gas blast pipeline to control the ingress and the egress of the external gas, therefore, when the heat-storage incinerator switches a gas flowing direction, the external gas blast pipeline is controlled to supply gas, and the high-concentration pollution of the heat-storage incinerator for switching the gas flow directions of two towers is eliminated to remove the exhaust gas pollution.

Description

technical field [0001] The present invention relates to a regenerative thermal incinerator for removing external air, in particular to a regenerative thermal oxidizer (RTO). , a waste gas inlet valve group, a leading control valve group, an external air supply pipeline and an external air control valve, which can make the regenerative combustion furnace switch the direction of the airflow when switching the direction of the airflow. Another function is that the unburned waste gas of the heat storage bed will not leak out, and the pollution peak of the operation will be generated to achieve the function of stable utilization. It is suitable for industries that need to reduce the generation of organic waste gas, such as some The production field of a specific industry, such as semiconductor industry, optoelectronic industry, chemical industry, etc. Background technique [0002] Volatile organic compounds (Volatile Organic Compound, VOC) are widely used in the industry, and ar...

Problems solved by technology

In the known regenerative incinerator 10a, when the inlet and outlet valves of the double-tower incinerator switch the direction of airflow during the operation cycle, a peak emission equivalent to the inlet concentration will be generated to the chimney (exhaust port). Due to the destruction of the organic waste gas by the incinerator The efficiency can reach more than 98%, and the inlet airflow will be directly discharged to the chimney when switching. Based on the 98% destruction efficiency estimate, it can be known that the concentration can reach 50 times higher than the exhaust gas treated by the incinerator, which has always caused the industry The disadvantage of the known regenerative incinerator is that when the air flow direction of the valve is switched, a pollution switching peak will be generated, and the lack of pollution makes it inconvenient and troublesome in practical applications
