Description
Technical field
The utility model relates to a kind of chemical separation device, especially a kind of device that reduces neutral oil content in the crude phenols.
Background technology
The neutral oil of phenolic product mainly is: alkane, alkene aromatic hydrocarbons, halohydrocarbon, alcohol, aldehyde, ketone etc.Refining sodium salt and crude phenols must not be sneaked into oil product in the middle of whole conveying, storage process.(GB) crude phenols neutral oil should be below 0.8% on request, and when crude phenols were made with extra care, neutral oil will be controlled at below 0.2%, and neutral innage can affect the subsequent product of refining of crude phenol.
At present, oiling processing enterprise all is with the simple device that blows method reduction crude phenols entrained oil that steams: neutral sodium-salt is static separator well in storage tank, neutral oil is wherein separated to greatest extent, the neutral sodium-salt of the static separation of process steams and blows, further remove neutral oil, reduce neutral oil content in the crude phenols, also there is part processing enterprise further to reduce the device of crude phenols entrained oil in research, but do not have one substantial progress is arranged, many clients are in a series of, waste, extensive working methods such as selection secondary processing.The present invention uses extraordinary extraction process can solve above all problems.
Summary of the invention
Existing steam the method for blowing to reduce crude phenols entrained oil device too simple in order to overcome, separate by static mode first during use, process is very long, is unfavorable for the problems such as fast industrialization operation, and the utility model provides a kind of device that reduces neutral oil content in the crude phenols.This device realizes that by the connection of equipment extraordinary extraction process reduces neutral oil content in the crude phenols, and is easy to use.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of device that reduces neutral oil content in the crude phenols comprises neutral phenol sodium salt storage tank, neutral carbolic oil extraction tower, mixing tank, extraction oil washing tower, extraction agent storage tank; Wherein neutral phenol sodium salt storage tank bottom is connected by pipeline A with neutral carbolic oil extraction tower, and neutral carbolic oil extraction tower top is connected with mixing tank by pipeline B, and neutral carbolic oil extraction tower bottom leads to steam blows tower or splitter; Add washing composition in the mixing tank, top leads to neutral phenol sodium salt storage tank, and the bottom is connected with the extraction oil washing tower; Extraction oil washing tower top connects the extraction agent storage tank, and the bottom also leads to neutral phenol sodium salt storage tank; The extraction agent storage tank is connected with pipeline A.
Washing composition described in the utility model is sodium hydroxide.
Extraction agent described in the utility model is carbolic oil class or kerosene.
The beneficial effects of the utility model are: the utility model reduces the device purpose of neutral oil content in the crude phenols, in order to solve the key link of above-mentioned technique bottleneck, he can provide one simple effectively, safety and environmental protection, continuous production be stronger, solves the device of crude phenols entrained oil.According to the principle of solvent oil absorption, utilize adsorb, separate, wash, reuse, the last device of extraction component.
The utility model solvent oil is reusable edible, the lightweight oils of carrying secretly in the extraction neutral phenol sodium salt.Not only significantly reduce subsequent product because carry oil product secretly and cause the low problem of quality product, and device is simple, environmental protection, continuous production are good, and tooling cost is low, successful.
Description of drawings
Fig. 1 is connection diagram of the present utility model;
