Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment catalytic combustion furnace. Background Art

[0002] Combustion furnace, arc combustion furnace is also known as carbon-sulfur combustion furnace, referred to as arc furnace, it is a device that uses high-voltage, high-frequency oscillation circuit to form an instantaneous large current to ignite the sample, so that the sample can be quickly burned under oxygen-rich conditions to produce a mixed gas, and after chemical analysis procedures, quantitatively and quickly analyze the carbon and sulfur content in the sample. It is the crystallization of many years of hard work of physical and chemical workers in my country. At present, some existing catalytic combustion furnaces for waste gas treatment do not have guide plates and filters inside. The waste gas is introduced from the feed port and flows directly out from the discharge port without circulating flow. The waste gas flows in the combustion furnace for a short time, and the waste gas purification may not be comprehensive. Some catalytic combustion furnaces for waste gas treatment are not equipped with insulation layers and heat insulation layers. When the heating plate is heated, due to the lack of insulation layers, it will take a relatively longer time to heat, resulting in a waste of resources. In addition, due to the lack of insulation layers, the heat is transferred to the outer wall of the combustion furnace, which can easily scald the working personnel, and the safety performance is low, which is not conducive to use.

[0003] In order to solve the above technical problems, a Chinese patent with announcement number CN211025539U in the prior art discloses a catalytic combustion furnace for treating degassing gas, comprising a combustion furnace body, a feed port is arranged at the upper left end of the combustion furnace body, a valve is arranged at the feed port, a discharge port is arranged at the lower right end of the combustion furnace body, a valve is arranged at the lower right end of the discharge port, three guide plates are arranged, and a filter screen is arranged on the guide plate, and the filter screen can filter impurities in the degassing gas.

[0004] Although the above-mentioned existing technical solution can prevent heat from being conducted on the inner wall of the combustion furnace, causing the outer wall of the combustion furnace to overheat and scald the staff, the filter screens are installed at the two ends of the inner side of the filter cylinder. After the filter screens have been used for a long time, a lot of dirt adheres to the surface, resulting in a decrease in filtering performance. It is difficult for the staff to remove the filter screens on each guide plate for cleaning, which in turn affects the subsequent filtering effect. Utility Model Content

After loosening the hanging ring, the positioning column 26 is inserted into the inner side of the sliding block 22 for positioning, and the assembly is completed. Conversely, after the positioning column 26 is inserted into the second positioning hole, the first guide plate 5 can be taken out, so as to disassemble and clean the filter screen 10 on the second guide plate, hold the handle to drive the sealing cover 4 to pull upward, so that the connecting block 6 is separated from the inner side of the connecting groove, and the magnetic block 7 and the iron block are separated and no longer adsorbed, and the sealing cover 4 can be removed to disassemble the first guide plate 5 or the filter screen 10.
