Description

Technical Field

[0001] The invention relates to the field of flue gas purification, in particular to a flue gas purification device for burning highland barley husks. Background Art

[0002] The cultivation areas of highland barley are mainly concentrated in Tibet, Qinghai, Sichuan and Yunnan in China. It is the main food of the Tibetan people. It has high nutritional value and is rich in protein, dietary fiber and various minerals. It is beneficial to human health.

[0003] After the highland barley is mature, it is generally shelled by a shelling machine. A large amount of highland barley husks need to be processed by incineration. However, during the incineration of highland barley husks, a large amount of smoke will be generated and directly discharged into the atmosphere, which will cause pollution to the atmosphere. The existing Chinese public patent document: CN218530414U discloses a flue gas purification device for a flue gas incinerator, in which the flue gas is introduced into the lower box body by the fan in the second installation cylinder. The filtrate can be an alkaline liquid that can purify toxic and harmful gases and particulate matter such as nitrogen oxides, carbon oxides, and hydrogen sulfide in the flue gas. A connecting device is provided on the first installation cylinder and the second installation cylinder. The insertion rod is moved inward by pressing the connecting rod. At this time, the first installation cylinder or the second installation cylinder can be installed. The cylinders are respectively inserted into the side walls of the upper box body and the lower box body, and then, through the restoring force of the spring, the insertion rod can be inserted into the insertion hole to complete the fixation of the first mounting cylinder or the second mounting cylinder. The first mounting cylinder or the second mounting cylinder can be disassembled and the connecting rod can be pulled in the opposite direction, which is convenient for disassembly and assembly of the first mounting cylinder and cleaning and maintenance of the fans therein. Although the two air intake and exhaust pipes can be quickly disassembled, as the flue gas purification increases, a large amount of particulate impurities will adhere to the surface of the activated carbon filter. In order to ensure the normal purification of the flue gas, the activated carbon filter needs to be replaced regularly. However, when replacing, the entire box needs to be disassembled, and normal flue gas purification cannot be performed, reducing the efficiency of flue gas purification. Summary of the invention
