Description

Technical Field

[0001] The invention relates to the field of activated carbon production, and in particular to a purification device for activated carbon production. Background Art

[0002] The role of activated carbon production is very extensive. It not only plays an important role in environmental protection and industrial production, but also shows its unique value in the fields of medicine and health, energy and many other aspects. With the advancement of science and technology and the growing demand for sustainable development, the application prospects of activated carbon will be broader.

[0003] In the early stage of activated carbon production, phosphoric acid, hydrochloric acid, caustic soda and other chemicals may be used in the raw material processing stage. These substances will produce organic gases (such as benzene, toluene, xylene, etc.), oxidizing gases (such as carbon dioxide, carbon monoxide, sulfur dioxide, oxygen, etc.) and water vapor during the high-temperature heating and regeneration process of activated carbon. If these waste gases are discharged directly without treatment, they will pollute the environment. Therefore, activated carbon production purification equipment is required to purify the waste gas, wastewater or other pollutants generated during the activated carbon production process.

[0004] Although the existing purification device for activated carbon production can already purify the exhaust gas, the impurities in the exhaust gas will adhere to the filter in the device and affect the function of the filter. The conventional method uses a brush, but this simple structure makes it easy for the impurities to be brushed into the holes of the filter. When the filter is cleaned, the device will stop purifying the exhaust gas generated during the activated carbon production, and the efficiency is not high. Summary of the invention
