Problems solved by technology

[0003] 1. At present, the pressurized transportation of raw coal is basically pulverized coal transportation; while the pressurized transportation of lump coal is only used in low-pressure conditions, which cannot meet the development of lump coal gasification;
[0004] 2. The cut-off valve for the pressurized transportation of raw coal adopts hard-sealed ball valves and dome valves. Due to frequent switching and material wear under pressurized conveying conditions, the cut-off valve has problems such as jamming, material accumulation, and abrasion in actual use. Reduced valve life

The block granular coal pressurizing conveyingdevice comprises a coal bin, a gate valve, an upper lock hopper valve, a coal lock hopper and a lower lock hopper valve which are successively connected from top to bottom, wherein the coal lock hopper is provided with a pressurizing valve and a pressure release valve. The block granular coal pressurizing conveying device and method makes up for the blank of the high-pressure conveying technologyof the block granular coal at the present stage, and meets the development demand of the block granular coal gasification.

Description

technical field [0001] The invention relates to the technical field of pressurized conveying, in particular to a pressurized conveying device and method for bulk granular coal. Background technique [0002] Today's coal gasification technology is a clean coal utilization technology in modern coal chemical industry. It has been developed rapidly in recent years, and various coal gasification technologies have been derived, especially pressurized gasification technology is widely used. Coal pressurized gasification technology is mostly pulverized coal gasification, and lump coal pressurized gasification technology is less; in order to meet the needs of technological development, the lump coal pressurized process has also been greatly improved. This process has high production efficiency under high temperature and high pressure conditions. Operation It is simple, has high material utilization rate, and can flexibly process a variety of coal and biomass. At the same time, the p...
