TECHNICAL FIELD

[0001] The utility model relates to the field of chemical production device, especially impregnated carbon activation boiling furnace with quick remove dust structure. BACKGROUND

[0002] The impregnated carbon material after the modified loading of activated carbon can effectively protect various harmful toxic agents and is the main filling material of protective equipment. In addition, the impregnated carbon material can also protect common industrial gases and is widely used in the fields of chemical industry, food, medicine, environmental protection, metallurgy and the like. With the rapid development of new energy, the main source of air pollution in China has changed to non-power industry, and the emission treatment of industrial gas has become a problem to be solved. In recent years, the demand for impregnated carbon with the function of adsorbing multiple pollutants increases year by year, and the boiling furnace, as the key equipment in the production and activation process of impregnated carbon, directly affects the quality of impregnated carbon products.

[0003] In the activation process of impregnated carbon, the airflow enters the hopper after being heated by the air inlet section. When the airflow reaches a certain flow rate, the impregnated carbon particles are blown up and turned up and down under the action of the airflow, forming a phenomenon similar to water boiling. During the boiling process, a large amount of carbon powder and dust and other pollutant particles are generated by the friction and collision between the material particles. In order to prevent the pollutant particles from being discharged into the air, most of the existing boiling furnaces block the particles in the furnace in the cloth bag by setting a high-temperature resistant cloth bag. However, when continuously producing for a long time, the particles continuously accumulate on the surface of the cloth bag, and the fine dust will block the cloth bag, causing poor air outlet, and the heat cannot be discharged in time, which may cause the material to catch fire in severe cases. In addition, the cloth bag dust removal cannot withstand the high temperature in the activation process, which has safety hazards and needs to be regularly inspected, disassembled, cleaned and replaced, which is not conducive to efficient and continuous production.
