Description

Can monitor and prevent leaking buffer tube Technical Field The utility model relates to the technical field of chemical equipment, in particular to a leakage-proof buffer cylinder capable of being monitored. Background In the coal water slurry gasification device, the abrasion-resistant pipeline behind the black corner valve 123FV193 valve of the washing tower releases the buffer barrel to play a vital role, however, the use condition of the buffer barrel is extremely severe, and the buffer barrel faces serious scouring and corrosion problems, specifically, after the pressure is reduced through the 123FV193 corner valve, the design pressure before the corner valve is 6.5MPa, and the design pressure after the corner valve is reduced to 0.9MPa, so that the flow rate of a medium in the pipeline is greatly increased, and the medium contains a large amount of fine slag particles, under the working condition, the fine slag particles continuously scour and abrade the buffer barrel behind the corner valve, so that the pipe wall is gradually thinned, even the condition of abrasive penetration leakage occurs, and great potential safety hazards are generated. At present, a standard buffer tube made of 316L material is generally adopted as a pipeline buffer tube behind a black angle valve of a washing tower of a gasification device, during normal operation, monitoring of the buffer tube mainly depends on nondestructive detection means such as fixed-point thickness measurement, but due to the limitation of the detection means and the influence of high-temperature environment in the operation process, on one hand, deviation can be caused in measurement, and on the other hand, the thickness of part of the buffer tube cannot be accurately measured, so that leakage frequently occurs at the later operation stage of the buffer tube, the production is in a passive situation, potential safety hazard is brought, and in order to ensure that leakage risks caused by corrosion and scouring are reduced in normal production operation, and meanwhile, the requirements of the angle valve on wear resistance, high-temperature resistance and corrosion resistance are fully met.
