Background

With the strict requirements of the national environmental protection regulations, the tar residue is used as solid waste and is not allowed to be discharged outside, and the tar residue needs to be recycled. In the coking production process, coal dust, semicoke and the like carried in coal gas are mixed in coal tar to form lumps with different sizes, and the lumps are called tar residues.

The tar slag is sticky waste slag, mainly comprises coal dust, coke powder, asphalt powder, free carbon generated by pyrolysis at the top of a carbonization chamber, and carbon-containing substances such as porous substances brought by cleaning of an ascending pipe and a gas collecting pipe, polymers of tar and asphalt and the like, is a semi-liquid substance and has viscosity. The content of fixed carbon in the tar residue is about 60%, the content of volatile matters is about 33%, the content of ash is about 4%, the fixed carbon can be combusted to generate heat, and the volatile matters are mainly polycyclic aromatic hydrocarbons. The tar and ammonia water generated by the coke oven enter a tar and ammonia water separation tank, the tar residue deposited at the bottom of the mechanical residue scraping tank is conveyed into the residue scraping tank by a tar residue pump for separation treatment, and the finer-particle tar residue is conveyed to a tar tank of an oil depot along with the tar by a tar pump and is deposited at the bottom of the tar tank.

At present, the process for preparing the briquette by the tar residue is widely adopted in China, the requirement on the quality of the tar residue is high, the tar residue deposited at the bottom of a tar tank is manually cleaned periodically, the tar residue is cleaned once every two years, the cleaning time lasts for about 1-2 months, and the cleaning method comprises the following steps: the tar slag at the bottom of the tar tank is added with coal powder according to 0.5-1 time of coal, the coal powder is dipped in the tar slag at the bottom of the thickened tank, a large amount of coal powder is mixed in the tar slag, the caking property is poor, the treatment requirement of coal blending is not met, the total amount of the tar slag is cleaned by about 600-800 tons every year, a large amount of tar slag is stacked in a coal yard, the tar slag belongs to dangerous waste, and the coal yard stacking does not meet the environmental protection requirement.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a tar residue recycling device and a using method thereof, and the tar residue recycling device has the advantages of recycling resources, reducing the amount of blended coal, saving coking coal and improving the economic benefit of enterprises.

The invention is further configured to: the side wall of the device platform is provided with an inclined ladder.

Through adopting above-mentioned technical scheme, the operation personnel are gone up and down to the inclined ladder convenience, improve the convenience of operation.

The invention is further configured to: all corner positions on the upper surface of the device platform are vertically connected with supports, and a canopy is connected between the tops of the four supports.

By adopting the technical scheme, the tar residues are drenched into rainwater and added into the blended coal to increase the moisture of the coal, so that the quality of the tar residues entering the furnace is influenced, and the canopy has the rainproof and sun-proof functions and can also improve the operating environment of operators.

The invention also provides a use method of the tar residue recycling device, which comprises the following steps:
