A heating stopping and cooling device on a waste oil recovering distillation tank comprises a cold oil tank arranged at the upper end surface of a distillation tank, the upper end surface of the cold oil tank is provided with a cold oil tank oil inlet, the lower end surface of the cold oil tank or the side surface of the cold oil tank close to the lower end surface is provided with a cold oil tank oil tube connected with the internal of the cold oil tank, and the other end of the cold oil tank oil tube is connected with the internal of a distillation tank. The upper portion of the distillation tank is provided with the cold oil tank, and the cold oil tank can rapidly cool the distillation tank, so the cooling efficiency is improved; and waste oil in the cold oil tank uses waste heat in the distillation tank to realize separation of diesel oil gases from other impurities in the distillation tank cooling process, so the waste heat utilization rate is improved, and energy is saved. The heating stopping and cooling device has the advantages of simple structure, convenient operation and maintenance, energy saving and high efficiency, and is very suitable for being promoted and enforced.
Description
technical field [0001] The invention belongs to the technical field of diesel oil refining in waste oil refining enterprises, and mainly relates to a cooling device and method for a waste oil recovery retort after cease-fire. Background technique [0002] In recent years, my country's oil imports are increasing year by year. Promoting the full utilization of energy has become a must for my country's economic development. It is foreseeable that the development of rich waste oil resources and the regeneration and utilization of waste oil will have great potential for development. Emerging industry. Extracting diesel oil from engine oil is one of them, but in the refining process, the cooling speed of the distillation tank is slow after the fire is stopped, and the production efficiency is low. If waste oil is added to the distillation tank before the temperature in the distillation tank has dropped to a suitable temperature, the waste oil may be ignited, and there is a huge po...
