Abstract

The invention provides a novel pulverized coal pyrolysis reaction charcoal burning circulation system, including a charcoal burner, etc., the cyclone separator of the charcoal burner is located in the charcoal burner, the cyclone separator of the settler is located in the settler, and the settler is located in the On one side of the charcoal burner, the external heat extractor and the charcoal burner are connected through an inclined pipe. The heat carrier riser passes through the bottom of the charcoal burner and is connected to the riser reactor. The main air distributor is located at the charcoal burner In the bottom of the device, one end of the U-shaped pipe for heat carrier circulation passes through the bottom of the charcoal burner and is connected to the main air distributor, the other end of the U-shaped pipe for heat carrier circulation is connected to the settler, and the air stripping section is located at the bottom of the settler Inside, one end of the riser reactor is connected to the settler, the other end of the riser reactor is connected to the heat carrier standpipe, and the main air pipe part passes through the bottom of the charcoal burner. The invention improves the utilization rate of pulverized coal resources and does not cause environmental pollution.

Description

technical field [0001] The invention relates to a reaction charcoal-burning circulation system, in particular to a pulverized coal pyrolysis reaction charcoal-burning circulation system. Background technique [0002] my country is a country with coal as its main energy resource, and this situation will not change for a long time to come. There are a large number of low-metamorphic coals, such as lignite and long-flame coal, distributed in northern Shaanxi, Inner Mongolia, and Yunnan-Guizhou. This type of coal has large resource reserves, shallow buried beds, good coal quality, low mining cost, good chemical activity, and high volatile content. , high calorific value, non-cohesive and other characteristics, it is beneficial to extract tar and chemical fuel gas through pyrolysis. [0003] The particle size of pulverized coal produced by coal mines is less than 6mm, the yield is over 50%, the price is much lower than that of lump coal, and there are problems such as transporta...
