Vibration ash removal device and using method thereof

Abstract

The invention provides a vibration ash removal device and a using method thereof.The vibration ash removal device comprises a high-pressure pneumatic section and a vibration section which are fixedlyconnected, the high-pressure pneumatic section is used for providing a closed high-pressure environment, an air cylinder in the closed high-pressure environment is made to provide kinetic energy through a piston, and therefore work is applied to the vibration section; and the vibration section is used for conducting kinetic energy released by the high-pressure pneumatic section and impacting internal parts of a gasification furnace, so that vibration ash removal is carried out on the inner wall of the gasification furnace. The vibration ash removal device integrates the advantages of vibrationash removal, that is, the vibration strength is controllable, the ash removal effect is good, the sealing effect is improved by arranging the multi-stage sealing assemblies of different combinations,and under the good sealing state, internal parts of the vibration ash removal device can be replaced and maintained under the condition that a gasification furnace is not stopped.

Description

technical field [0001] The invention relates to the field of vibration ash removal devices, in particular to a multi-stage sealed vibration ash removal device. Background technique [0002] In the late 1990s, dry coal pulverized gasification technology was favored by many domestic coal chemical companies because of its advantages of significantly improving coal utilization and reducing production costs. A difficult subject. A large amount of dust generated by coal gasification is easy to adhere to the water wall of the gasifier, which greatly reduces the heat transfer efficiency, causes the outlet temperature of the gasifier to rise sharply, and even causes the entire system to automatically shut down. The vibration ash removal device applied to the dry coal gasification process is the key device to ensure the normal operation of the coal gasification equipment. Vibrating ash removal device, also known as mechanical rapper, is generally arranged at various angles around th...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the disadvantages of easy leakage and short service life of the existing vibration ash removal device, the present invention provides a vibration ash removal device, which integrates the advantages of vibration ash removal, that is, the vibration intensity is controllable, and the ash removal effect is good. The sealing effect is improved by setting different combinations of multi-stage sealing components, and in a well-sealed state, the internal parts of the vibration ash removal device can be replaced and repaired without stopping the gasifier
