[0002] In the new coal chemical industry, the purified sulfur recovery device is an important environmental protection facility. The sulfur component in the raw coal gas undergoes an oxidation-reduction reaction to recover sulfur through the Claus sulfur recovery device, ensuring that the sulfur content in the tail gas meets the emission standards. During the operation of the sulfur recovery device, the sulfur cooler outlet pipeline is prone to blockage, and the liquid sulfur cannot be discharged normally to the liquid sulfur lock bucket, which increases the pressure of the combustion furnace. When the blockage is serious, it will cause the sulfur recovery device to interlock and the tail sulfur to exceed the standard. Therefore, when the liquid sulfur pipeline is initially blocked, the liquid sulfur pipeline must be cleared online in time. When clearing the liquid sulfur pipeline, the blind cover behind the sulfur cooler outlet pipeline valve must be removed. After clearing, a large amount of sulfur will be sprayed out, which will not only cause ground environmental pollution, but also bring greater safety risks to the clearing operation.
