A novel distillation system of a hydrocarbon cleaning machine

Abstract

A novel distillation system of a hydrocarbon cleaning machine is provided. The system include a filter, a transit tank, a first heat exchanger, a second heat exchanger, a first-grade distillation tank, a second-grade distillation tank, a pure liquid tank and a drainage tank. Hydrocarbon sewage is filtrated through a filter tank to obtain a hydrocarbon filtrate; the hydrocarbon filtrate is temporarily stored in the transit tank; the hydrocarbon filtrate in the transit tank is fed into the first heat exchanger, preheated by the first heat exchanger and then fed into the first-stage distillationtank; hydrocarbon steam obtained by distilling the hydrocarbon filtrate through the first-stage distillation tank is fed into the first heat exchanger for heat exchange with the hydrocarbon filtrate,and is then cooled in the second heat exchanger to obtain pure liquid, with the pure liquid being fed into the pure liquid tank; hydrocarbon sewage obtained by distilling the hydrocarbon filtrate in the first-stage distillation tank is fed into a sewage tank, and then fed into the second-grade distillation tank, and recovered hydrocarbon steam obtained after distillation and the hydrocarbon steamobtained by distillation with the first-grade distillation tank are combined and cooled by the two heat exchangers in order to obtain pure liquid, with the pure liquid being fed into the pure liquid tank; and the hydrocarbon sewage obtained after distillation in the second-stage distillation tank is fed into the drainage tank.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a novel hydrocarbon cleaning machine distillation system. Background technique [0002] At present, the distillation system of the known hydrocarbon cleaning machine generally injects the dirty liquid hydrocarbon directly into the evaporation tank. On the one hand, there is no pre-filtering of impurities, which leads to the impurity particles entering the tank and depositing them. On the other hand, the hydrocarbon liquid is not preheated. It is directly poured into the tank to cook into steam, resulting in too long cooking time and excessive loss of heat energy, resulting in unnecessary waste. In addition, there are still some hydrocarbons that cannot evaporate and accumulate in the tank. After a long time, the effusion will increase and the impurities will increase. The composition of effusion is that hydrocarbons are mixed with dirty liquid oil and impurity pa...
