Problems solved by technology

Because phenolic plastics are thermosetting plastics, they cannot be reused after use, but can only be discarded, seriously polluting the environment, and due to the huge amount of phenolic plastics used, there are a lot of waste phenolic plastics produced at one time

Embodiment 1

[0020] The waste nitrile rubber from the market is cooled and torn into small pieces of 5mm after heating in a 100°C double-roller heating machine, and then fully mixed with waste phenolic plastics smaller than 2mm. The mass of nitrile rubber accounts for 10% of the mass of waste phenolic plastics After mixing, the mixed material is smelted on the rollers at 100°C with a double-roller heat smelter. The heat smelting time is 5 minutes. After the heat smelted material is cooled, it is added to the crusher and crushed to less than 1.5mm, and then blended with coal according to a certain proportion. Fully mix, the composition of the blended coal is Ad=8%, VMd=26%, the weight of the mixture of nitrile rubber and waste phenolic plastic accounts for 6% of the weight of the blended coal, and the mixed material is added to the pulverizer for crushing, crushed The final particle size is less than 1mm, and finally put into a 40kg coke oven to pyrolyze to form coke under a certain heating ...

Embodiment 2

[0022] The waste nitrile rubber from the market is cooled and torn into small pieces of 8mm after heating in a 100°C double-roller heat mixer, and then fully mixed with waste phenolic plastics smaller than 2mm. The mass of nitrile rubber accounts for 12% of the waste phenolic plastics. After mixing, the mixed material is smelted on the rollers at 110°C with a double-roller heat smelter. The heat smelting time is 7 minutes. After the heat smelted material is cooled, it is added to the crusher to be crushed to less than 1.5mm, and then blended with coal in a certain proportion. Fully mix, the composition of the mixed coal is Ad=9%, VMd=25%, the weight of the mixture of nitrile rubber and waste phenolic plastic accounts for 7% of the weight of the mixed coal, and the mixed material is added to the pulverizer for pulverization, pulverized The final particle size is less than 1mm, and finally put into a 40kg coke oven to pyrolyze to form coke under a certain heating system, and cool...

Embodiment 3

[0024] The waste nitrile rubber from the market is cooled and torn into small pieces of 12mm after heating in a 100°C double-roller heating machine, and then fully mixed with waste phenolic plastics smaller than 2mm. The mass of nitrile rubber accounts for 13% of the waste phenolic plastics. After mixing, the mixed material is smelted on the rollers at 120°C with a roller smelter. The smelting time is 8 minutes. After the smelted material is cooled, it is added to the crusher and crushed to less than 1.5mm, and then blended with coal according to a certain proportion. Fully mix, the composition of the blended coal is Ad=10%, VMd=24%, the weight of the mixture of nitrile rubber and waste phenolic plastics accounts for 8% of the weight of the blended coal, and the mixed material is added to a pulverizer for crushing, crushed The final particle size is less than 1mm, and finally put into a 40kg coke oven to pyrolyze to form coke under a certain heating system, and cool by CDQ.

Abstract

The invention relates to a method for producing coke through co-coking coal and waste / used phenolic plastics. The method for producing the coke through co-coking the coal and the waste / used phenolic plastics is characterized by comprising the following steps: (1) carrying out mixing and cooking on butadiene-acrylonitrile rubber and the waste / used phenolic plastics; (2) crushing treated plastics; (3) blending and crushing the treated plastics and matching coal; and (4) carrying out coking test on coal blend. According to the method for producing the coke through co-coking the coal and the waste / used phenolic plastics, disclosed by the invention, an effective method is provided for utilizing the waste / used phenolic plastics by co-charring butadiene-acrylonitrile rubber, the waste / used phenolic plastics and coking coal, the environmental pollution caused by the waste / used phenolic plastics is reduced, and meanwhile, part of replacing raw materials are provided for the shortage of coking coal resources, so that the method has very good economic and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of high-temperature pyrolysis of coal into coke, comprehensive utilization of waste plastics and environmental protection, and specifically relates to a method for co-coking coal and waste phenolic plastics to produce coke. Background technique [0002] Due to the rapid development of economic construction, the plastic industry has developed rapidly. The plastics after processing and production are increasing day by day. In 2010, the output of plastics in the world market exceeded 250 million tons. And my country has become a veritable plastic production, consumption and importing country. Due to the corrosion resistance, drug resistance and aging resistance of plastic itself, it exists in nature for a long time and is difficult to degrade, causing serious "white pollution". The "white pollution" produced by waste plastics is not only an environmental problem, but also a social problem. Environmental prote...
