Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a rotary heat storage heating furnace. Background Art

[0002] With the rapid development of industry, industrial production will be accompanied by the emission of waste gas containing various components. However, for the protection of the environment, the waste gas needs to be treated before being discharged into the atmosphere. Some industrial waste gas contains halogens and other elements in the organic matter, and the oxidation product contains hydrogen halide. The waste gas needs to be burned for thermal oxidation to increase the temperature of the gas. The organic matter is basically converted into carbon dioxide and water. The purified gas can be discharged after reaching the discharge standard. The heating furnace is used to thermally oxidize the waste gas. In order to save energy, a regenerative heating furnace is often used. The regenerative heating furnace consists of a heating furnace body, a regenerative chamber, a reversing system and a smoke exhaust system. The principle is to heat the air to above 760 degrees Celsius, and the organic matter in the waste gas is oxidized and decomposed into carbon dioxide and water. The high-temperature gas generated by oxidation passes through the ceramic regenerative body to heat up the ceramic regenerative body and store heat. This heat storage is used to preheat the subsequent waste gas that has not been thermally reduced, thereby saving fuel consumption for waste gas heating.

[0003] In the current heat storage heating furnace, the direction of the air flow in the furnace depends on the cooperation of the inlet and outlet valves, so that the various heat storage chambers are used alternately. The pipeline distribution is complex, and it is necessary to accurately control the opening and closing of each valve. The air injection ports in different directions are opened. According to the use of the heat storage chamber, the air injection ports in the corresponding directions are opened to inject back-blowing airflow to control the direction of the exhaust gas in the furnace. However, the back-blowing airflow is not preheated and directly contacts with the preheated exhaust gas, which will affect the preheating effect. Utility Model Content
