Problems solved by technology

The tar residue in the coking plant belongs to the category of hazardous waste. The simple method of burying or pouring into the sea to transfer pollution cannot be used to dispose of the tar residue in the coking plant. At present, some oil residues are treated by separation, and the separated oil residue is added to coal blending for re-coking. , but the final tar residue obtained by this method still contains about 10% to 15% of water and about 9% to 10% of tar, so it is sticky and hardened and has a strong pungent smell, which affects the accuracy of transportation and coal blending , is not good for the environment

Embodiment 1

[0095] A treatment system for tar residue, comprising a pretreatment tank 101 and a separator 104; the pretreatment tank 101 includes a pretreatment tank body and a jacket 5 arranged outside the body; the pretreatment tank 101 is provided with A reduction motor 1, the output end of the reduction motor 1 is connected with a rotating shaft, the rotating shaft is provided with an agitator 6, and the agitator 6 is arranged in the pretreatment tank body; There is a sieve plate 11 above the agitator 6, the rotating shaft rotates through the sieve plate 11, and a tar residue scraper 10 and a tar residue scraper 10 located above the sieve plate are oppositely arranged on the side wall of the rotating shaft along the circumferential direction. Liquid wheel 8; the sieve plate 11 is horizontally arranged, and is detachably connected with the inner wall of the pretreatment tank body; the sieve hole of the sieve plate 11 is a circular hole with a diameter of 10mm, and the distance between t...

Embodiment 2

[0103] A treatment system for tar residue, except that there are two steam pipes with a diameter of 30 mm, and other conditions are the same as in Example 1.

[0104] A treatment method for tar residue, using the above-mentioned treatment system for tar residue, comprising the following steps:

[0105]Take 1.5 tons of oil residue from the mechanized clarification tank in the coking plant and enter the pretreatment tank through the feed port, add 200kg of diesel oil and 30kg of sulfur agent in the pretreatment tank, and insert the steam pipe evenly into the pretreatment tank to keep the tank at 70 °C, fully Stop stirring well, pump the hot tar slurry into the separator, flow the separated oil and water into the underground tank (tar tank) from the bottom, send the separated tar residue into the cooler, and dry the tar residue out of the cooler to powder Send into the coal blending system and blend the coal into coke; the gram of sulfur agent is the same as in Example 1.

Embodiment 3

[0107] A treatment system for tar residue, except that the diameter of the steam pipe is 30mm, other conditions are the same as in Example 1.

[0108] A treatment method for tar residue, using the above-mentioned treatment system for tar residue, comprising the following steps:

[0109] Take 1 ton of tar residue produced in the process of tar fractionation and refinement through the pretreatment tank at the feed inlet, add 300 kg of phenol oil and 200 kg of sulfur agent, and insert the steam pipe vertically and evenly into the pretreatment tank to keep 65 ℃, stir well without stopping, use a pump to pump the hot tar slurry into the separator, flow the separated oil and water into the underground tank (tar tank) from the bottom, send the separated tar residue into the cooler, and put the separated oil and water into the cooler. The dry powder of the tar residue is sent to the coal blending system for coal blending to make coke; the gram sulfur agent is the same as in Example 1....

Abstract

The invention relates to the technical field of degreasing, in particular to a tar residue treatment method and system. The treatment method of the tar residue comprises the following steps: stirring a mixture of the tar residue, a sulfur gram agent, a tar solvent and steam under a heat preservation condition, and then carrying out solid-liquid separation. According to the treatment method of the tar residue, the phenomenon that the tar residue is difficult to treat in a coking enterprise is fundamentally solved, a certain amount of sulfur-gram agent is added to overcome tar viscosity and remove stink, and the tar residue is dried into residue powder with low water content and low tar content, so that coal blending is accurate, the tar separation rate is high, and tar income is increased. The tar residue powder obtained by the drying method disclosed by the invention is dry, loose and non-sticky, and is convenient to transport, so that coal blending is accurate, and the coke quality is ensured; and the process is simple and convenient and has high automation degree.

Description

technical field [0001] The invention relates to the technical field of degreasing, in particular to a treatment method and system for tar residue. Background technique [0002] With the further stringent national environmental protection policies, coking enterprises are facing more and more serious situations in energy saving, emission reduction and environmental protection work. How to reduce pollution and reduce emissions has always been the top priority for the development of coking enterprises. The tar residue in the coking plant belongs to the category of hazardous waste. The simple method of burying or pouring into the sea to transfer pollution cannot be used to dispose of the tar residue in the coking plant. At present, some oil residues are treated by separation, and the separated oil residue is added to coal blending for re-coking. , but the final tar residue obtained by this method still contains about 10% to 15% of water and about 9% to 10% of tar, so it is stick...
