Embodiment Construction

[0024] use Figure 1 to Figure 2 A coal slag decarburization method of the present invention is described as follows.

[0025] Such as figure 1 and figure 2 Shown, a kind of coal slag decarburization method of the present invention, this method comprises the steps:

[0026] Step 1: Put the coal slag into the coal chemical gasification furnace slag decarburization grinder and grind it into coal slag powder, and make the temperature of the coal slag powder higher than the ambient temperature, which can reduce the temperature in the subsequent fluidized bed from being lowered to reduce energy consumption;

[0027] Step 2: After the coal slag is ground into powder in step 1, air is introduced into the fluidized bed, the temperature of the air is controlled at 650-720°C, and the flow rate of the air is 20-40m 3 / h, subsequently, drop the coal carbon slag powder in the fluidized bed;

[0028] Step 3: After putting the coal carbon slag powder into the fluidized bed in step 2, k...

Abstract

The invention belongs to the technical field of gasifier coal gas slag, and concretely relates to a coal carbon slag decarburization method. The method comprises the following steps: adding coal carbon slag into a coal chemical industry gasifier slag decarburization grinder, and grinding the coal carbon slag to form coal carbon slag powder; introducing air into a fluidized bed, controlling the temperature of the air to be 650-720 DEG C and the flow of the introduced air to be 20-40 m<3> / h, and then adding the coal carbon slag powder into the fluidized bed; and reacting the coal carbon slag powder in the fluidized bed for 20-40 min to obtain carbon slag having a free carbon content of 2 wt% or below in order to complete the decarburization of the coal carbon slag. The coal chemical industrygasifier slag decarburization grinder improves the coal carbon slag decarburization method, and makes the coal carbon slag fully ground and crushed before being decarburized, and the crushed coal carbon slag powder is heated, so the improvement of the decarburization effect of the coal carbon slag is benefited; and the temperature and the flow of the air in the gasifier are controlled to make thecoal carbon slag fully reacted in the gasifier, so the decarburization effect of the coal carbon slag is improved.

Description

technical field [0001] The invention belongs to the technical field of gasifier coal slag, in particular to a method for decarburizing coal slag. Background technique [0002] With the rapid development of economy and technology, people are paying more and more attention to resource utilization and environmental issues. The slag produced after coal combustion will pollute the environment. Therefore, collecting and reusing slag is currently the only way to deal with slag. One of the methods is that before using the slag, it needs to be crushed and decarbonized so that the waste slag can be used again. The slag is crushed, and after the slag is crushed, the slag is decarburized so that the slag can be used again. At present, when the existing slag is processed, the decarburization effect of the slag is not ideal, especially the crushing of the slag and the decarburization effect of the slag in the gasifier are not ideal. Contents of the invention [0003] In order to make ...
