A distillation petroleum oil dehydration device

Abstract

The invention belongs to the field of chemical industry, and more specifically relates to a distillation method petroleum dehydrating device. The distillation method petroleum dehydrating device comprises an accommodating mechanism, a stirring mechanism, a condensation mechanism, a preheating mechanism, a distilled water receiving water bucket, a petroleum conveying mechanism, a heating mechanism,and a driving mechanism; a cooling bucket and a fixed bucket are communicated through a hot water outlet pipe; cold water in the cooling bucket is heated after condensation of water in a cooling pipe, and flows to the side wall of the fixed bucket through the hot water outlet pipe; the side wall of the fixed bucket is winded by the hot water outlet pipe in a S-shaped manner for preheating of petroleum in the fixed bucket; preheated petroleum is heated to a certain temperature, and is pumped into the heating bucket using a petroleum pump. Fuel is saved; waste heat utilization effect is excellent; waterwheel principles are adopted to realize circulation rotation of a plurality of water receiving boxes, and a first rotating shaft is driven by a second rotating shaft to rotate; stirring of petroleum in the heating bucket and accelerating of petroleum dehydration speed are achieved.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a distillation petroleum oil dehydration device. Background technique [0002] Distillation is a thermodynamic separation process. It utilizes the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense them to separate the entire components. There are two types of evaporation and condensation. A union of unit operations. Compared with other separation methods, such as extraction, filtration and crystallization, its advantage is that it does not need to use other solvents other than the system components, so as to ensure that no new impurities will be introduced. It is a viscous, dark brown liquid. Known as the "blood of industry," there are oil deposits in parts of the upper crust. [0003] However, in the traditional distillation petroleum oil dehydration device, the hot water after coolin...
