Problems solved by technology

At the same time, in the regeneration of waste oil, the waste heat of the flue gas from the exhaust gas burner is not utilized, and the discharge temperature of the flue gas greatly exceeds the standard
Waste heat is not utilized, resulting in high energy consumption and high production costs for waste oil regeneration
On December 15, 2017, the company applied for a patent titled "A waste heat utilization device for waste oil regeneration rectification catalytic system", the patent number is 2017217512881. This device separates the top line oil and gas from the fractionation tower Partial recovery of the waste heat is used to heat the waste oil, and the top-line oil gas is continuously cooled by water to form liquid oil. The amount of waste oil heated by this device is small, the temperature of the waste oil is also low, and the speed of heating the waste oil is also fast. Slow and insufficient utilization of waste heat

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 ...
