Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, and more specifically, relates to a waste gas treatment device and treatment method for the production process of traditional Chinese medicine. Background Technology

[0002] The waste gas generated during the drying process of Chinese medicinal herbs contains a large amount of particulate matter, volatile organic compounds and trace amounts of harmful substances. If directly emitted, it will pollute the atmospheric environment and may also affect the quality of Chinese medicinal herbs through adhesion and other means. The irritating and toxic substances in these waste gases will harm the respiratory and nervous system health of production employees and surrounding residents.

[0003] The currently used waste gas treatment devices still have the following problems: 1. They cannot provide auxiliary cooling for waste gas, which affects the service life of the activated carbon mesh, and they also cannot provide auxiliary preheating for the air entering the drying equipment, which increases power consumption and results in poor energy saving; 2. The waste gas treatment devices have poor stability after long-term use, and the particulate filter cannot be automatically cleaned when the activated carbon mesh is replaced, which increases the difficulty of cleaning; 3. When the relevant parts are not accurately reset after the activated carbon mesh is replaced, they cannot automatically prompt the staff, which affects the subsequent waste gas treatment effect.
