Problems solved by technology

[0003] At present, the incinerators used in the domestic coal chemical solid incineration treatment process use fuel oil or gas as auxiliary fuel. This treatment method has high operating costs, incomplete incineration effect, and uneven furnace temperature, which is prone to local overheating , in addition, the heat generated by incineration has not been recycled, resulting in a waste of energy resources

Embodiment Construction

[0031] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0032] A coal chemical industry solid slag reuse method, characterized in that: the method comprises the following steps:

[0033] Step 1: Transporting the coal chemical industry solid slag to the crushing furnace 1 and performing rolling and crushing treatment;

[0034] Step 2: discharge the air in the intermediate furnace 2 into the incinerator 3 to support combustion;

[0035] Step 3: transporting water vapor to the intermediate furnace 2 to moisten the coal chemical solids;

[0036] Step 4: discharge the gas in the incinerator 3 into the crushing furnace 1 to prevent blocking the hole at the bottom of the crushing furnace 1;

[0037] Such as Figure 2 to Figure 8 As shown, the crushing furnace 1 in the step 1 and step 4 includes a screw con...

Abstract

The invention belongs to the field of coal chemical solid processing, and in particular relates to a coal chemical solid slag recycling method. The method includes step 1 of conveying coal chemical solids into a crushing furnace and performing crushing treatment; step 2 of discharging air in an intermediate furnace into an incinerator to assist combustion; step 3 of conveying vapor into the intermediate furnace to wet the coal chemical solids; and step 4 of discharging gas in the incinerator to prevent holes at the bottom of the incinerator from being blocked. According to the coal chemical solid slag recycling method, the coal chemical solids can be fully burned, heat generated by the combustion is utilized, and the method is an effective way to achieve the recycling of coal chemical solid resources and improve energy utilization rate.

Description

technical field [0001] The invention belongs to the field of solid treatment in coal chemical industry, in particular to a method for reusing solid slag in coal chemical industry. Background technique [0002] For the treatment process of coal chemical solids, the traditional mainstream storage and landfill treatment and disposal methods can no longer meet the national requirements for environmental protection and sustainable development, and there are certain environmental hazards and risks of occupying a large amount of land resources and polluting groundwater. Therefore, the realization of The resource utilization and reduction treatment of coal chemical solid waste has become one of the current environmental protection problems that need to be solved urgently. Coal chemical solid incineration technology is a kind of thermochemical treatment technology, which can realize the recovery and reuse of thermal energy resources. This technology has many advantages, such as good...
