Abstract

The invention discloses a waste heat recycling system of a complete set of waste oil treatment equipment, and relates to a heating device for waste oil regeneration. The system is characterized in that a bottom line oil heat exchanger, a side line oil heat exchanger, a flue gas rear-section heat exchanger and a flue gas front-section heat exchanger form four-stage heating of waste oil; a heating medium of the bottom line oil heat exchanger is bottom line oil of a fractionating tower, a heating medium of the side line oil heat exchanger is side line oil of the fractionating tower, a heating medium of the flue gas rear-section heat exchanger is flue gas of the rear section of a waste gas burner, and a heating medium of the flue gas front-section heat exchanger is flue gas of the front section of the waste gas burner; the bottom line oil heat exchanger and the side line oil heat exchanger are horizontal cylindrical tank bodies with the same structure, and the flue gas rear-section heat exchanger and the flue gas front-section heat exchanger are vertical hanging type tank bodies with the same structure; and four stages of waste oil heaters are connected in series through pipelines and pipe fittings. The system is scientific and reasonable in structure, safe and reliable, saves energy, reduces the cost of waste oil regeneration, greatly improves high-temperature emission of flue gas, facilitates emission and has popularization value.

Description

technical field [0001] The invention relates to a heating device for waste oil regeneration, and more specifically to a waste heat recovery and utilization system of waste oil complete processing equipment. Background technique [0002] In the regeneration of waste oil, especially in the complete set of waste oil treatment equipment, a large amount of electricity is required to heat the waste oil, and the heating temperature of the waste oil needs to be determined according to the type of waste oil regeneration and the regeneration process. In the process of rectifying and catalytically regenerating waste oil, it is necessary to heat the waste oil to 200°C-400°C to vaporize the waste oil and separate the bottom line oil, side line oil and top line oil gas. In waste oil regeneration, the bottom line oil, side line oil, and top line oil gas separated by the fractionation tower need to be cooled. In the past, the bottom line oil and side line oil were all cooled naturally, and ...
