Description

Technical Field

[0001] The utility model relates to the technical field of high-sulfur recovery, in particular to a sulfur recovery mechanism for petrochemical high-sulfur waste gas. Background Art

[0002] Petrochemicals and petrochemicals, petrochemicals is a process involving the extraction, conversion and application of oil and natural gas, including oil refining and petrochemicals. Oil refining is the process of extracting various fuels and lubricants from crude oil, while petrochemicals is the process of using these raw materials to produce various chemicals. High-sulfur waste gas refers to a type of waste gas with a high sulfur content, which mainly comes from the combustion of sulfur-containing fuels such as oil and natural gas. Hydrogen sulfide is the main component of high-sulfur waste gas. It is a colorless, foul-smelling gas that is very harmful to the environment and human health.

[0003] A sulfur recovery mechanism for high-sulfur waste gas from a petrochemical industry with announcement number CN 215610512 U is disclosed. The sulfur recovery mechanism for high-sulfur waste gas from a petrochemical industry has a sealing plate welded to the bottom end of a connecting rod to prevent liquid in a water tank from splashing onto the operator's hands and causing damage to the operator's hands, thereby improving the safety of the device. At the same time, the liquid in the water tank is collected into a collection box through a collection trough, and dust is collected through the collection box, thereby improving the convenience of the device.

[0004] In the sulfur recovery mechanism of the petrochemical high-sulfur exhaust gas, the first push plate drives the sealing plate to move through the connecting rod, and the sealing plate no longer blocks the water tank, which facilitates the discharge of the liquid in the water tank and prevents the liquid in the water tank from splashing onto the operator's hands and causing damage to the operator's hands. However, the device requires the staff to rotate the sealing cover. When wastewater remains in the drain pipe, the wastewater in the drain pipe is easy to splash onto the staff's hands and cause damage to the staff, so it needs to be improved. Utility Model Content
