Problems solved by technology

At present, most coking enterprises return the tar slag to the coal yard, mix it with coal directly, and then use it for coking. Since it is difficult to mix the tar slag and coal evenly, it is not conducive to the improvement of coke quality to directly return it to coking.
[0003] With the upgrading of consumption in our country, waste rubber and waste plastics are increasing day by day. If they are not handled properly, it will cause environmental pollution and waste of resources.

Embodiment 1

[0014] In the first step, put 4% of waste rubber granules, 1% of waste plastic granules, and 95% of coking decrystallized anthracene oil into the reaction kettle, and heat them with steam to 180-220°C for dissolution to obtain rubber mixed anthracene Oil;

[0015] In the second step, according to the ratio of rubber mixed anthracene oil 22%, tar residue 22%, and road construction oil 56%, put the three into the mixing heating tank, first use steam to heat to about 300°C, and then use gas to slowly heat to 360°C ℃ and keep it for half an hour, when the temperature drops to more than 250 ℃, stir to prepare the briquette binder.

[0016] The third step is to mix the two according to the ratio of briquette binder 6% and mixed coal 94%, and add an appropriate amount of water to prepare briquette slime with a water content of 11%-13%.

[0017] Step 4: send the briquette slime to the briquette machine to press into briquettes of the required shape, and when the briquettes are natura...

Abstract

The invention discloses a method for preparing a coke-making briquette, which comprises the following main steps: 1. waste rubber particles and waste plastic particles are added into anthracene oil according to the proportion and are heated and dissolved, then tar slag and road construction oil are added according to the proportion and are heated and stirred to produce briquette adhesive; 2. the briquette adhesive is added into mixed coal according to the proportion, and a small amount of water is added to be mixed and stirred to produce briquette pug containing certain moisture; and 3. the briquette pug is sent to a briquette machine and is pressed into briquette blocks, and a finished product of the coke-making briquette can be obtained when the briquette blocks are air-dried until the content of the moisture is between 8 and 10 percent. The method utilizes the tar slag, waste rubber, and waste plastic to produce the briquette adhesive, and provides a new way for the reasonable utilization of the tar slag, the waste rubber and the waste plastic; and the tar slag, the waste rubber, the waste plastic and coal all have macromolecular structures consisting of C and H elements and have better cosolvency, thereby contributing to improving the quality and yield of coke after the co-carbonization.

Description

technical field [0001] The invention belongs to the technical field of coal chemical industry, and in particular relates to a method for preparing briquette coal for coking by using tar residue and waste rubber. Background technique [0002] Tar residue is a waste residue discharged from the coking production process. The rational use of tar residue is of great significance to protect the environment and save resources. At present, most coking enterprises return the tar slag to the coal yard, mix it with coal directly, and then use it for coking. Since it is difficult to mix the tar slag and coal evenly, it is not conducive to the improvement of coke quality to directly return it to coking. [0003] With the upgrading of consumption in our country, waste rubber and waste plastics are increasing day by day. If they are not handled properly, it will cause environmental pollution and waste of resources. [0004] Therefore, it is necessary to constantly seek new rational utiliz...
