Problems solved by technology

[0002] After coal is burned, coal slag or slag will be formed. During the actual combustion process of coal, a hard shell will be formed on the surface of the slag formed. Due to the existence of the shell, part of the coal inside the slag will not be burned. If the slag is directly Treating as garbage will be a waste of resources

Embodiment Construction

[0026] In order to make the technical methods, 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.

[0027] Such as figure 1 Shown, a kind of coal chemical gasification furnace slag recycling method of the present invention, the method comprises the following steps:

[0028] S1, using a coal mill to grind the slag into coal powder;

[0029] S2, the pulverized coal in S2 is sent to the heat exchanger through the blower, and the pulverized coal is ignited in the heat exchanger;

[0030] The coal mill adopted in the method comprises a feed hopper 1, a grinding mechanism 2, a mounting plate 3, a support mechanism 4, a discharge hopper 5, a drying mechanism 6, a crushing mechanism 7, a feeding mechanism 8 and a blocking mechanism 11; The bottom end of the feed funnel 1 is installed with the crushing mechanism 7 for crushing the slag, and the top o...

Abstract

The invention specifically relates to a recycling and reusing method for the gasifier slag of the coal chemical industry, belonging to the technical field of recycling and reusing of energy. The recycling and reusing method for the gasifier slag of the coal chemical industry comprises the following steps: S1, grinding the gasifier slag into coal dust by using a coal pulverizer; and S2, conveying the coal dust obtained in the step 1 into a heat exchanger via a blower and igniting the coal dust in the heat exchanger. According to the method, the gasifier slag is crushed by using a grinding manner, so coal inside a shell is exposed; then powdery particles obtained after grinding are introduced into the heat exchanger for combustion; so a coal resource is sufficiently utilized.

Description

technical field [0001] The invention relates to the technical field of energy recovery and reuse, in particular to a method for recovery and reuse of slag in a coal chemical gasification furnace. Background technique [0002] After coal is burned, coal slag or slag will be formed. During the actual combustion process of coal, a hard shell will be formed on the surface of the slag formed. Due to the existence of the shell, part of the coal inside the slag will not be burned. If the slag is directly Treating it as garbage will be a waste of resources. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides a method for recovering and reusing the slag of a coal chemical gasifier. This method crushes the slag by grinding to expose the coal inside the shell, and then grinds the slag into powder The particles are passed into the heat exchanger for combustion, so as to realize the full utilization of coal resources. [0004] Th...
