Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to a sulfur recovery device used in the petrochemical industry. Background Art

[0002] The sulfur recovery system in the petrochemical industry is mainly composed of a preheating device, a combustion furnace, a cooler, a recovery reactor and a collection device. In the existing sulfur recovery system, the preheating device and the combustion furnace are often set separately, which causes the energy carried by the preheated mixed gas to be easily lost during the transportation process, and it is easy to liquefy when it encounters cold, which not only causes heat loss, but also affects the chemical reaction of the mixed gas in the combustion furnace.

[0003] Announcement No. CN 209668764 U is a highly effective sulfur recovery device for the petrochemical industry. By setting a U-shaped tube and an acid drying plate, the preheated mixed gas will flow into a filter box, where the oil, ash and water vapor mixed in the mixed gas can be removed in turn. By shortening the gas transportation distance, the gas can not only reduce heat loss during the entire transportation process, but also avoid the gas entering the combustion furnace from carrying moisture, thereby improving the processing quality of the mixed gas in the combustion furnace.

[0004] The sulfur recovery device for the petrochemical industry with high benefits can filter the gas through the filter plate, but the device is not provided with a device for cleaning the filter plate, so when the filter plate is blocked by dust, the staff needs to disassemble the filter plate. When the filter plate is disassembled, the device cannot be used, and the time for replacing the filter plate is long, which greatly affects the work efficiency, so it needs to be improved.
