Problems solved by technology

[0002] At the present stage, most of the waste treatment technologies still stay in the way of incineration, landfill, and cement kiln collaborative treatment, and there are relatively few industrialization projects for transformation and utilization, resulting in a considerable amount of hazardous waste that is difficult to process
Especially for more than 20 oil wastes involved in HW08 and HW-900 categories, for example, mixed oil materials such as mineral residues, coal chemical tar, plant and animal waste oils, etc., if it is impossible to treat the above oil wastes Effective treatment will cause environmental pollution and waste of resources and energy

Embodiment 1

[0038] The conversion agent in this embodiment includes a functional compounding agent and a catalytic assistant. Among them, the functional compounding agent includes the following components and raw materials in weight percent: 9-17% of titanium acyl ion, 18-23% of amide polyether, 5-13% of polyethylene polyamine, and 5-8% of dimethylglyoxime , ethanol 28-35% and ethyl acetate 16-23%. The catalytic promoter includes the following components and raw materials in parts by weight: tetrahydrofurfuryl alcohol 10-15%, trichloroethane 13-18%, pyrrolidone 10-16%, 4-chlorophenol 22-25%, diethanolamine 20- 25% and ammonia 9-17%.

[0039] Preferably, in the functional compounding agent, the weight ratio of titanium acyl ion, amide polyether, polyethylene polyamine, dimethylglyoxime, ethanol and ethyl acetate is 17:18:13:8:16:28. Preferably, in the catalyst promoter, the weight ratio of tetrahydrofurfuryl alcohol, trichloroethane, pyrrolidone, 4-chlorophenol, diethanolamine and ammoni...

Embodiment 2

[0042] The preparation method of the transforming agent of this embodiment comprises the following steps: according to 9-17% of titanium acyl ion, 18-23% of amide polyether, 5-13% of polyethylene polyamine, 5-8% of dimethylglyoxime, 28% of ethanol -35% and ethyl acetate 16-23% components and parts by weight are mixed as raw materials, and the mixed raw materials are stirred evenly at a temperature of 50-60 DEG C to obtain a functional compounding agent. According to the composition and weight of 10-15% tetrahydrofurfuryl alcohol, 13-18% trichloroethane, 10-16% pyrrolidone, 22-25% 4-chlorophenol, 20-25% diethanolamine and 9-17% ammonia water The raw materials are mixed according to the number of parts, and the mixed raw materials are stirred evenly at normal temperature to obtain the catalytic promoter.

[0043] Wherein, the functional compounding agent and the catalyst auxiliary agent are prepared and stored separately, so as to be taken separately. In specific applications, ...

Embodiment 3

[0045] In this embodiment, the method for applying conversion agent to treat oily waste comprises the following steps:

[0046] Oily waste is transferred to the reactor.

[0047] Add the functional compounding agent and stir at normal temperature for 5-15 minutes, then stop stirring and stand for 15-25 minutes to react, and then discharge the precipitated sewage; wherein, the dosage of the functional compounding agent is 0.1-10%.

[0048]Adding a catalyst booster, heating to 110-130 degrees centigrade, maintaining a constant temperature and stirring for 15-25 minutes, completing dehydration and deodorization, and obtaining a converted product; wherein, the amount of the catalyst booster is 1-20%.

[0049] Preferably, before the oily waste is transferred into the reactor, the oily waste is filtered through a pretreatment tank.

[0050] Preferably, the functional compounding agent is added and stirred at room temperature for 10 minutes, then the stirring is stopped and the reac...

Abstract

The present invention discloses a method for treating oily waste with a conversion agent, which includes transferring the oily waste into a reactor; adding a functional complex agent and stirring at normal temperature for 5-15 minutes, then stopping the stirring and standing for 15 minutes ‑25 minutes, and then discharge the precipitated sewage; wherein, the dosage of the functional compounding agent is 0.1‑10%; add the catalyst promoter, and heat to 110 to 130 degrees Celsius, keep stirring at a constant temperature for 15‑25 minutes to complete the dehydration Deodorization to obtain converted products; wherein, the amount of the catalyst promoter is 1-20%; the invention also discloses a conversion agent and a preparation method thereof. The application can innovatively process oily waste and transform it into value-added products, and the whole process is efficient and fast, without secondary pollution, high economic value, and suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of energy and chemical engineering, in particular to a method for treating oily waste with a transforming agent, a transforming agent and a preparation method thereof. Background technique [0002] At this stage, most of the waste treatment technologies still stay in the way of incineration, landfill, and cement kiln co-processing, and there are relatively few industrialization projects for transformation and utilization, resulting in a considerable amount of hazardous waste that is difficult to process. Especially the more than 20 oily wastes involved in the HW08 category and the HW-900 category, for example, mixed oily materials such as mineral residues, coal chemical tar, vegetable and animal waste oils, etc., if the above-mentioned oily wastes cannot be Effective treatment will cause environmental pollution and waste of resources and energy. Contents of the invention [0003] Aiming at the deficiencie...
