Anti-clogging device for liquid level in quenching chamber of gasifier

Abstract

The invention relates to a liquid level anti-blocking device for a chilling chamber of a gasification furnace. The liquid level anti-blocking device comprises a pressure taking pipe communicated with the chilling chamber and a flange type pressure transducer mounted at the outer end of the pressure taking pipe, wherein a flushing water ring is arranged between the pressure taking pipe and the pressure transducer; a through hole for communicating the surface of a film box of the pressure transducer with the pressure taking pipe is formed in the middle of the flushing water ring; a water inlet channel communicated with an external pipeline is formed in the side wall of the flushing water ring; a water outlet of the water inlet channel is formed in the end face of the flushing water ring on one side of the pressure taking pipe; a flushing water pipe, of which one end is connected with the water outlet formed in the end face of the flushing water ring, is arranged in the pressure taking pipe; the outlet end of the flushing water pipe is arranged in the pressure taking pipe leading to one side of the chilling chamber. High-pressure flushing water is led to one side close to the chilling chamber, so that settling of smudgy mediums can be prevented, the service life of a liquidometer can be prolonged, and the safety of gasification furnace running is improved.

Description

Technical field [0001] The invention relates to a Texaco gasification furnace of coal water slurry gasification equipment, in particular to a liquid level anti-clogging device of the quenching chamber of the gasification furnace. Background technique [0002] Texaco gasifier is a widely used coal water slurry gasification equipment. The coal water slurry and oxygen undergo gasification reaction in the combustion chamber of the gasifier. The crude synthesis gas and molten ash enter the water bath of the quench chamber down, and most of the molten slag falls into the bottom of the quench chamber after cooling and solidification. The crude synthesis gas From the annular gap between the downcomer and the air duct, the quenching chamber rises to the scrubber. The synthesis gas is cooled, ash removed and humidified in the quench chamber. The quench chamber must maintain a certain water level to not only meet the needs of quenching, but also to ensure that the downcomer is protected fr...

AI Technical Summary

Problems solved by technology

Due to the high water pressure, regardless of long-term or intermittent flushing, the high-pressure water column entering the pressure-taking pipeline will cut the surface of the bellows. damaged by oil spill

Moreover, due to the impact of the flushing water pressure during the flushing process, the liquid level gauge cannot be used, which brings safety hazards to production
