Durable water-coal-slurry gasification furnace water distributor

Abstract

The invention discloses a durable water-coal-slurry gasification furnace water distributor which comprises an immersed pipe seat (1), a water inlet channel (2) is formed in the immersed pipe seat (1), and water distribution holes (3) connected with the water inlet channel (2) are uniformly formed in the immersed pipe seat (1). The durable water-coal-slurry gasification furnace water distributor is characterized in that the cross section of each of the water distribution holes (3) is formed by combining a square with a side length of 20 mm and two semicircles with a respective diameter of 20 mm on the two sides of the square; a helical angle of 25 degrees is formed in each of the water distribution holes (3), a quenching ring (4) is connected to the rear end of the immersed pipe seat (1) and an outlet of the water distribution holes (3), a wear resistant layer (5) is arranged on the inner side of the quenching ring (4), a continuous smooth transition structure is formed in a position where the quenching ring (4) is connected with the water distribution holes (3), and a water outlet is formed in the other end of the quenching ring (4). The durable water-coal-slurry gasification furnace water distributor disclosed by the invention can effectively solve the problem of poor high-temperature erosion resistance and ensures that the service lives of an inlaid ring, the quenching ring and a down comer are greatly prolonged.

Description

technical field [0001] The invention relates to a durable water distributor for a coal-water slurry gasifier, belonging to the technical field of water distributors. Background technique [0002] In the use of 62M3 / h coal-water slurry gasifier, the gasifier water distributor is used for two and a half cycles, that is, after about 75 working days, the chilling ring of the gasifier water distributor usually appears to be " If the chilling ring is perforated, if it continues to be used, there will be a large number and large diameter perforations in the chilling ring in about ten working days. The function of the chilling ring itself is to evenly distribute the chilling water in the downcomer On the inner surface of the pipe, and form a layer of water film to flow down with the synthesis gas, to isolate the direct contact between the high-temperature synthesis gas and the downcomer, and to protect the downcomer from deformation caused by high temperature, and the damage of the ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a durable water distributor for coal-water slurry gasifier, which can effectively solve the problem of poor high-temperature erosion resistance of the quenching ring, and ensure that the service life of the ring, quenching ring and downcomer is greatly improved. The range is increased, so that the equipment has safer operating conditions and more reliable safety guarantees, improves production efficiency, and can overcome the shortcomings of existing technologies
