Abstract

The present invention belongs to the technical field of coal gasification and particularly discloses a coal gas preparation technology. The technology uses a gasification furnace; a material feeding passage, a furnace body and a waste residue chamber are sequentially arranged; a grinding device is arranged in the material feeding passage; first air bags are arranged under the grinding device; thebottom part of the material feeding passage is provided with a vibration plate; one end of the vibration plate is hingedly connected on the outer wall of the furnace body; the other end of the vibration plate is connected with a piston rod of a first cylinder through a spring; a combustion chamber is arranged inside the furnace body; a spirally arranged spiral plate is arranged in the combustion chamber; the bottom of the spiral plate is intervally provided with a vibration module along the direction of the spiral plate; and an output end of a flame generator is connected to an input end of aflame sprayer. The used gasification furnace in the technology improves combustion efficiency of pulverized coal by the grinding device and the spiral-shaped spiral plate; heat is used to evaporate water in the inner cavity of the spiral plate to drive an eccentric wheel, so that the grinding device is detached from a motor to achieve grinding, thereby improving the working efficiency of the device and saving resources.

Description

technical field [0001] The invention belongs to the technical field of coal gasification, in particular to a coal gas preparation process. Background technique [0002] At present, the world's crude oil reserves are very tight, so its price is very high. In order to alleviate this pressure, cheap coal is often chosen to replace high-cost crude oil. To this end, the state proposes a clean energy policy and adopts various measures for the rational use of coal. Coal gasification technology is the core leading technology of all coal chemical industries, whether it is IGCC cogeneration, or coal-to-oil, coal-to-natural gas, coal-to-olefins, coal-to-synthetic ammonia and other chemical products, efficient and clean coal gasification production equipment Technology will certainly be able to significantly reduce its production costs. Among them, the gasifier plays a key role in the coal gasification equipment. There are many types of gasifiers, and the fluidized bed generator is on...
