A method and device for gasification, pyrolysis, catalytic regenerative combustion of organic matter

Abstract

The invention provides an organic matter gasification pyrolyzation catalysis heat storage burning method and device and belongs to the technical field of environment protection. Organic fuels enter a perforating type gasification pyrolyzation section through a feeding inlet, and generated gasification pyrolyzation gas enters a catalysis heat storage burning section; cross heat storage carriers are installed in the catalysis heat storage burning section, and the surfaces of the cross heat storage carriers are provided with catalysts, so that the gasification pyrolyzation gas can mix with air, is subjected to hypoxia superinsulated burning in a short time simultaneously, and is burned completely in a free reaction section; the high temperature smoke generated from burning enters a heat transfer section, the heat transfer section is divided into a plurality of districts to ensure sufficient heat transferring; the smoke enters a ceramic purification section to be purified after heat transferring; and ashes generated in the gasification pyrolyzation process are transported to a sealed dry-type ash discharging section through a vertical spiral ash removing and air supplying integrated device. The organic matter gasification pyrolyzation catalysis heat storage burning device can be used as various reactors such as hot water boilers, steam boilers and hot blast heaters and has the advantages that the application range of organic matters is wide; burning reaction time is short; heat transferring is complete; the volume of the entire device is small; and tail gas does not need to be deacidified or subjected to oxynitride removing.

[0002] Direct combustion of organic matter will produce a large amount of SO x and NO x , the result is that the cost of tail gas treatment is extremely high, how to realize the absorption of pollutants in the device is the key to solving this problem

[0003] The gasification of organic matter is one of the most promising methods for large-scale utilization of the energy contained in it. However, a large amount of tar will be produced during the gasification of most organic matter, and the tar entrained in the gas will be lost during the transportation to the subsequent process. Condensed into liquid, the condensed tar and the entrained fly ash adhere together, which is easy to block the gas pipeline, valve and gas transportation equipment, affecting the normal and stable operation of the system. At the same time, the existence of tar also reduces the gasification efficiency of organic matter. seriously hinders its large-scale application
