Problems solved by technology

The disadvantage of this process method is that the generated gas has a high moisture content, and the moisture in the gas comes from the low-temperature dry distillation pyrolysis water of the fuel, the moisture in the fuel and the undecomposed part of the steam
Due to the cooling effect in the post-treatment process, the phenol produced in the pro...

Embodiment Construction

[0023] In order to better understand the present invention, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] (1) Drying of raw coal

[0025] The coal loading trolley loads the raw coal into the single bell jar coaling box 2, and then the raw coal enters the coal hot air drying furnace 1, and the raw coal in the coal hot air drying furnace 1 is released into the super-speed guide exchanger in the gas purification and cooling process. The heated section is contacted with air at 50-300°C, and is slowly heated during the descent process. When it reaches about 110°C, the surface moisture and absorbed moisture in the coal are completely removed, and only a very small part of the combined moisture remains. The dried coal finally falls out from the lower coal outlet and enters the upper coal hopper 5.

[0026] (2) dry distillation process

[0027] The dried raw coal is fed from the upper coal h...

Abstract

The invention belongs to the coal gas generation filed, in particular to a normal pressure non-phenol method of the fixed bed coal gas generator; the technical proposal includes that the method includes the steps of dry distillation segment process and gasification segment process in the coal gas generator; the raw coal is dried before the raw coal is fed into the coal gas generator; 95 % water contained in the raw coal is removed through high temperature by the process method before the raw coal is fed into the coal gas generator; finally, the water content of the generated coal gas is lowered greatly; thereby, the generation quantity of the phenol is reduced obviously.

Description

technical field [0001] The invention belongs to the field of gas generation, and in particular relates to a normal-pressure phenol-free method for a fixed-bed gas generator. Background technique [0002] The process method of the gasifier commonly used at present is two steps: the process step of the dry distillation section and the process step of the gasification section in the gasifier. The details of this step are when the raw coal containing a large amount of After the coal burner is added, it is in reverse contact with a part of the hot coal gas produced in the dry distillation section and gasification section, and loses moisture and volatile matter after being heated. After the volatile matter is removed in the dry distillation section, the coal material becomes low-temperature dry distillation semi-coke and enters the gasification section. They are in countercurrent contact with steam and air in the gasification section, and all the carbon is almost completely gasifi...
