Problems solved by technology

This method of on-site operation by the staff not only wastes manpower, but also relies too much on the experience of the operator. The quality of the liquid separation depends entirely on the experience and techniques of the operator. It is inevitable to release some toluene resin solution, resulting in material loss.

Embodiment 1

[0028] Embodiment 1 A kind of automatic liquid separation device of liquid epoxy resin water washing process

[0029] An automatic liquid separation device for the washing process of liquid epoxy resin, comprising: a detection unit located at the liquid outlet of the washing kettle 1, a branch pipe between the detection unit and the connecting pipe of the toluene resin collection tank 6, and a branch pipe connected to the branch pipe. Liquid recovery device, and background control unit.

[0030] Using the above device, the detection unit collects the detection index of the effluent from the washing tank and transmits it to the background control unit; according to the detection index, the background control unit controls the automatic cut-off valve of the liquid separation recovery device, so as to realize the separation of the mixed liquid in the washing process in the washing tank Collect work.

[0031] Preferably, the detection unit is a detection device grasped by those s...

Embodiment 2

[0035] Embodiment 2 A kind of tertiary amine oil washing process automatic liquid separation device

[0036] An automatic liquid separation device for the tertiary amine oil washing process, comprising: a detection unit located at the liquid outlet of the water washing kettle 1, a branch pipe arranged between the detection unit and the connecting pipe of the tertiary amine oil collection tank 6, and a branch pipe connected to the branch pipe. Liquid recovery device, and background control unit.

[0037] Using the above device, the detection unit collects the detection index of the effluent from the washing tank and transmits it to the background control unit; according to the detection index, the background control unit controls the automatic cut-off valve of the liquid separation recovery device, so as to realize the separation of the mixed liquid in the washing process in the washing tank Collect work.

[0038] Preferably, the detection unit is a detection device known by t...

Embodiment 3

[0042] Embodiment 3 One kind utilizes the device described in embodiment 1 to carry out automatic liquid separation method to liquid epoxy resin washing liquid (DCS carries out automatic control according to the reading of conductivity meter)

[0043] The crude epoxy resin obtained in the upstream synthesis process contains a large amount of salt and by-products, and a washing process is required; specifically: add an appropriate amount of toluene and an appropriate amount of water to the crude epoxy resin, open the washing tank, stir and let it stand for a certain period of time. time, start to wash for the first time; after the first washing, the high-salt wastewater formed needs to be separated (that is, liquid separation collection) out of the washing kettle.

[0044] The liquid separation collection is as follows: collecting the effluent of the washing kettle, collecting the indicators of the effluent at the same time, and remotely transmitting the indicators to the backgr...

Abstract

The invention relates to an automatic organic matter water washing liquid separation device and liquid separation method thereof, in particular to an automatic liquid separation device and an automatic liquid separation method for a liquid epoxy resin water washing procedure. The automatic liquid separation device for the organic matter water washing liquid comprises a detection unit located at aliquid outlet of a water washing kettle, a branch pipe arranged between the detection unit and a connecting pipeline of an organic matter collecting tank, a separated liquid recovery device connectedwith the branch pipe, and a background control unit. In the liquid separation process of the organic matter water washing liquid, the device and the method can effectively avoid the influence caused by human factors, realize automatic operation, avoid material loss, greatly improve the personnel efficiency and improve the productivity of the device.

Description

technical field [0001] The invention relates to an automatic liquid separation device and liquid separation method for organic washing liquid in the process of chemical synthesis, mainly aimed at the automatic liquid separation device and liquid separation method in the refining water washing stage of liquid epoxy resin production process, and belongs to the field of chemical synthesis. Background technique [0002] During the reaction of epoxy resin, a large amount of sodium chloride, a small amount of aging resin (epoxy resin polymer) and some side reaction products (epichlorohydrin hydrolyzed into glycerin under alkaline conditions) will be produced. At present, the production of epoxy resin adopts the process of extraction and water washing to separate the liquid epoxy resin from the above materials, and the extraction agent generally uses toluene. The epoxy resin is extracted by toluene. After the extraction, the method of washing with water is adopted to dissolve and r...
