Example Embodiment

[0020] Example 1

[0021] A method for efficiently disposing of solid waste ion exchange resin is completed according to the following steps:

[0022] 1) Mix solid waste ion exchange resin into lean coking coal. Technical requirements for solid waste ion exchange resin: Fe 2 O 3 Content ≤50%, SiO 2 ≤50%, ash content≤10%, St,d≤0.5%. Control the mixing quality of waste solid ion exchange resin to 0.05% of the total lean coking coal;

[0023] 2) The lean coking coal mixed with waste solid ion exchange resin enters the pulverizer to be pulverized and fully mixed;

[0024] 3) The mixed coal of solid waste ion exchange resin and lean coking coal is sent to the coal blending coking system, and the mass ratio of the mixed coal is 6.5%.

[0025] The use of solid waste ion exchange resin for remixing coking does not affect the quality of coke and replaces the corresponding amount of lean coking coal to reduce the cost of coal blending. The average monthly re-allocation amount is 12 tons. The an...

[0027] A method for efficiently disposing of solid waste ion exchange resin is completed according to the following steps:

[0028] 1) Mix solid waste ion exchange resin into lean coal. Technical requirements for solid waste ion exchange resin: Fe 2 O 3 Content ≤50%, SiO 2 ≤50%, ash content≤10%, St,d≤0.5%. Control the mixing quality of waste solid ion exchange resin to 0.1% of the total lean coal;

[0029] 2) The lean coal mixed with waste solid ion exchange resin enters the pulverizer to be crushed and mixed thoroughly;

[0030] 3) The mixed coal of solid waste ion exchange resin and lean coal is sent to the coal blending coking system, and the mass ratio of the mixed coal is 7%.

Abstract

The invention relates to an efficient treatment method for solid waste ion exchange resin. The method includes: 1) blending solid waste ion exchange resin into single coal, and controlling the blending mass of the solid waste ion exchange resin not more than 0.1% of the total amount of the single coal; 2) crushing the single coal mixed with the solid waste ion exchange resin in a crushing machineand mixing the substances fully; and 3) sending the mixed coal of step 2 into a coal blending coking system, and controlling the mass ratio of the mixed coal not more than 7%. The method provided by the invention utilizes a coke oven for coking of solid waste ion exchange resin blended with coal, not only solves the environmental protection problem, but also has no great influence on the coke quality. Use of solid waste ion exchange resin to blend with coal for coking can replace a corresponding part of single coal consumption and reduce the coal blending cost.

Description

technical field [0001] The invention relates to the field of coal blending and coking, in particular to a method for efficiently treating solid waste ion exchange resins. Background technique [0002] The ion exchange resin produced by water treatment is a high molecular polymer with ion exchange group function. During the water treatment process, a large number of harmful ions and even heavy metal ions are adsorbed. At present, landfill treatment is commonly used at home and abroad, which has long-term potential risks. , Once it enters the environment, it will cause serious pollution. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for efficiently treating solid waste ion exchange resins, effectively treating solid waste resins and avoiding environmental pollution. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A method for efficiently tr...
