Coal chemical industry pyrolysis and gasification system

Abstract

The invention belongs to the technical field of coal chemical industry, and concretely relates to a coal chemical industry pyrolysis and gasification system. The system comprises a shell, a combustionchamber and a grinding chamber; the grinding chamber is arranged in the top of the shell; a water tank is mounted at one side of the shell, a filtering tower is arranged at the other side of the shell, the filtering tower is communicated with the combustion chamber, and a first rotating rod and a spiral plate are arranged at the bottom of the combustion chamber; the top end of the first rotatingrod is fixedly connected with a cam; the cam is connected with a driven wheel through a belt, and the driven wheel is connected with a second bevel gear through a second rotating rod; a grinder is arranged in the grinding chamber, and a grinding block is arranged at one side of the grinding chamber; the bottom of the grinding block is connected with an airbag through a spring; a grinding head is arranged at the other side of the grinding chamber, and the grinding head is provided with circumferentially uniformly-distributed protrusions; the grinding head is connected with a first bevel gear through a first connecting rod; and a mounting block is arranged at one end of the first connecting rod. Coal briquettes are crushed by the grinder, and then are combusted, so the gasification efficiency of the coal briquettes is improved.

Description

technical field [0001] The invention belongs to the technical field of coal chemical industry, in particular to a coal chemical pyrolysis gasification system. 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. In addition, my country's dependence on crude oil and natural gas is also increasing year by year. Therefore, it is of great significance to my country's energy strategy to seek a comprehensive coal utilization route with less resource consumption, high energy conversion efficiency, high oil and gas yield, good semi-coke quality, maximized product benefits, energy conservation and emission reduction. The gasifier plays a key role in coal gasification equipment. There are many types of gasifiers, and...

Problems solved by technology

The utility model realizes the full utilization of the pulverized coal particles through the cooperative use of the first filtering mechanism and the second filtering mechanism; the oxygen content required for pulverized coal combustion is increased through the oxygen pipeline, and at the same time, the oxygen ejected from the nozzle has a strong impact on the alumina ceramics The filter plate is backflushed to achieve repeated combustion; however, the combustion efficiency of pulverized coal in this technical solution still needs to be further improved
