Embodiment 1

[0011] 17 among the figure is the gasification furnace of the present invention, and gasification furnace 17 is made up of shell 3, coal gas outlet 12, slag outlet 1 and feed port 4, feed port 5, feed port 6, and shell 3 lining Insulation material 8 and refractory material 7, the lower part of the shell 3 is the slag outlet 1 and the water seal 2, and the interior can be divided into three areas, from top to bottom are the cooling area 18, the reduction area 19, the combustion area 20, and the cooling area The inner wall of the housing 3 of 18 is lined with a water jacket 10, and the water jacket 10 has a water inlet 9 and a water outlet 11. In the lower part of the housing 3, there are a primary feed port 4, a secondary feed port 6, and a feed port It is connected with the feeding device, which is composed of a carbon dioxide storage tank 13, a pulverized coal storage tank 14, an oxygen storage tank 15, and a steam storage tank 16 to supply raw materials for the gasifier. The...

Embodiment 2

[0013] According to Embodiment 1, in order to ensure the supply of carbon dioxide and the stability and easy control of production, a special carbon dioxide feed port 5 can be set, which is communicated with the carbon dioxide storage tank 13 separately, and the primary feed port 4 and the secondary feed port 6 are connected to the carbon dioxide storage tank 13. Other storage tanks are connected.

Abstract

The invention belongs to a fine coal gasification generator, in particular to a fine coal gasification furnace which can reduce the emission of carbon dioxide and improve the yield of coal gas. A gasification furnace and a feeding device are used as main production devices, and fine coal, water and oxygen are used as main raw materials. The technical key points are as follows: the gasification furnace is provided with a carbon dioxide feeding port which is communicated with a carbon dioxide storage tank and by which carbon dioxide is supplied to the gasified coal, and the carbon dioxide takes part in the reaction in the gasification furnace, thereby improving the yield of the coal gas and reducing the emission of the carbon dioxide.

Description

technical field [0001] The invention belongs to a pulverized coal gasification generating device, in particular to a pulverized coal gasification furnace capable of reducing carbon dioxide emissions. Background technique [0002] In the prior art, the coal gas produced by the coal gasification furnace is mainly used for the production of synthetic ammonia and methanol. During the whole production process, a large amount of carbon dioxide will be produced, most of which are directly discharged into the atmosphere, causing air pollution. Existing devices for coal gas generation, such as Patent Application No. 200520047515 published by the State Patent Office, design a multi-nozzle coal water slurry or pulverized coal gasifier for gasification of coal water slurry or pulverized coal. The gasification chamber is composed of a shell, a process nozzle chamber, a process nozzle, a preheating burner chamber, and a preheating burner. The composition of the mouth can make the carbon ...
