Problems solved by technology

[0003] In the design of crushed coal pressurized gasification technology and BGL crushed coal pressurized gasification technology, many conveying machinery and equipment are used in the slagging method of the gasifier. Since the material to be transported is slag, the equipment wears seriously, and often occurs during the operation of the equipment. The equipment leaks water and air, the operating environment is very poor, the workload of equipment maintenance is heavy, and the production cannot be continuous

Embodiment 1

[0022] A slag discharge ditch is arranged under the ground in the gas-making plant. There is a cover plate (1) on the tunnel (2), and a slag discharge ditch (3) is arranged at the center of the bottom of the tunnel (2). The tunnel (2) and the slag discharge ditch (3 ) is a plugging end; the other end leads to the ash pool, the slope of the bottom of the tunnel (2) and the slag ditch (3) is: a=3%, the tunnel (2) is 2 meters high, and the width: 1000mm. The slag ditch is equipped with panels, and the paneling material is cast stone panels. The paneling material at the vertical ash pipe falling place in the gasification plant should be cast iron panels, and the paneling radius of the slag flushing ditch is R=175mm. The plugging end of the slag ditch (3) is the high end, and the end leading to the ash pool is the low end. The low end of the slag ditch (3) is connected to the ash pool. composition, the cover plate (1) is provided with an air outlet (10), and when the pulverized coa...

Embodiment 2

[0024] The slope of the bottom of the tunnel (2) and the slag flushing ditch (3) is: a=4.5%, the tunnel (2) is 2 meters high, the width is 1200mm, and the panel radius R of the slag flushing ditch is R=300mm. The diameter of the vertical ash pipe is: 1400mm, and the height of the vertical ash pipe is: 10000mm. The ash outlet (7) of the ash discharge pipe (6) is inserted into the slag-washing ditch at a height of 700 from the bottom of the slag-washing ditch, and the gray-water ratio is formed in the slag-washing ditch, and the gray-water weight ratio is 1:20. The water maintains a flow velocity of V=3.5m / s. All the other are the same as embodiment 1

Embodiment 3

[0026] The slope of the bottom of the tunnel (2) and the slag-washing ditch (3) is: a=4%, the tunnel (2) is 2 meters high, the width: 1100mm, and the paneling radius R=200mm of the slag-washing ditch. The diameter of the vertical ash pipe is: 1100mm, and the height of the vertical ash pipe is: 9000mm. The ash outlet (7) of the ash discharge pipe (6) is inserted into the slag-washing ditch at a height of 600 from the bottom of the slag-washing ditch, and the gray-water ratio is formed in the slag-washing ditch, and the gray-water weight ratio is 1:15. The water maintains a flow velocity of V = 3.0 m / s. All the other are the same as embodiment 1

Abstract

The invention relates to a hydraulic slag discharging method of a crushed coal pressurized-gasification furnace, which comprises the following steps: arranging a vertical ash box at the lower part of an ash lock of a crushed coal pressurized-gasification furnace, inserting an ash discharging pipe of the vertical ash box in a slag runner to maintain a certain height from the bottom of the slag runner so as to enable part of the ash slag to be discharged from the ash discharging pipe, aligning a slag flushing sprayer to the ash slag stack to form a certain ash-water ratio in the slag runner, and maintaining the water in the slag runner at a relatively high flow speed to flush the ash slag into an ash slag pool. By using the hydraulic ash slag flushing mode instead of mechanical ash slag conveying mode, the invention greatly improves the operation environment of gas making factory buildings, reduces the pollution to the environment, and has the advantages of less device overhaul workload and reliable production run.

Description

technical field [0001] The invention belongs to a method for removing slag from a pressurized gasifier, in particular to a hydraulic method for removing slag from a crushed coal pressurized gasifier. Background technique [0002] At present, the crushed coal pressurized gasification technology, BGL crushed coal pressurized gasification technology, liquid slag coal gasification technology and pulverized coal gasification technology (such as GSP gasification technology) have been widely used in synthetic ammonia, synthetic methanol and synthetic methane, etc. in industrial production practice. The slag discharge method of these gasifiers used to be a scraper slag extractor or a screw slag extractor, and the slag conveyed by the scraper slag extractor was transferred to the belt conveyor for slag discharge. [0003] In the design of crushed coal pressurized gasification technology and BGL crushed coal pressurized gasification technology, many conveying machinery and equipment ...
