Description
Technical Field

[0002] During the production and use of emulsions, emulsion wastewater may be generated, which contains a certain amount of oil and emulsifiers. The oil-water separator is a glass instrument used in the laboratory. These wastewaters need to be treated through the oil-water separator to achieve the purpose of environmental discharge or resource recovery.
[0003] However, while pursuing separation efficiency, traditional oil-water separators often ignore the cleanliness and ease of operation of the equipment, resulting in difficult equipment maintenance, unstable separation effect, and cumbersome operation. Therefore, an emulsion R&D laboratory oil-water waste liquid separation device is needed to solve the problems of cleanliness and efficiency of the oil-water separator. Utility Model Content
[0004] The purpose of the invention of the utility model is to provide an oil-water waste liquid separation device for an emulsion research and development laboratory in order to solve the problems of cleanliness and efficiency of the oil-water separator.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an oil-water waste liquid separation device for an emulsion research and development laboratory, comprising a liquid separation container, the liquid separation container is provided with a lid, the liquid separation container is a straight cylindrical container with an opening on the top, the bottom end of the lid is an inverted V-shaped structure, the lid is provided with condenser ventilation holes and condenser reflux holes, the condenser ventilation holes and condenser reflux holes are both arranged on the edge of the lid and close to the inner wall of the liquid separation container, the liquid separation container is also provided with a first drain port and a two-phase fluid port, the first drain port is connected to a first drain pipe, a joint is provided between the first drain port and the first drain pipe, the two-phase fluid port is connected to a two-phase fluid pipe, a joint is also provided between the two-phase fluid port and the two-phase fluid pipe, the joint comprises a nut and a threaded tube.
[0006] When the oil-water separator is used, the gas-liquid mixture in the external distillation device passes through the two-phase fluid pipe, the joint, the two-phase fluid port, the liquid separation container and the condenser ventilation hole in sequence and enters the external condensation device. After the gas-liquid mixture is condensed into liquid by the condensation device, the liquid flows back from the condenser reflux hole to the liquid separation container. Under the guidance of the condenser reflux hole and the inverted V-shaped cover, the liquid flows back to the bottom of the liquid separation container along the condenser reflux hole and the inner wall of the liquid separation container. This structure and method can prevent the liquid from dripping directly from the condensation device into the liquid separation container, causing the oil and water that have been separated in the liquid separation container to mix again, thereby providing Oil-water separation efficiency; due to the different densities of oil and water, water usually gathers at the bottom of the separation container, and oil usually gathers at the top of the water. The first drain port is used to discharge the oil in the oil-water mixture. The straight-cylindrical separation container has no dead angle, which is convenient for the staff to clean the separation container; the nut and the threaded pipe of the joint are adapted to each other for detachable connection, the first drain port is connected to the first drain pipe through the joint, and the two-phase fluid port is connected to the two-phase fluid pipe through the joint, so that the first drain pipe and the two-phase fluid pipe can be easily removed, which is convenient for cleaning the first drain pipe and the two-phase fluid pipe, saving time and helping to improve work efficiency.

[0008] As a preferred solution of the utility model, the conical connector is made of soft material. The material of the soft seal is usually made of soft materials such as rubber, polytetrafluoroethylene, etc. When the sealing surface is subjected to pressure, these materials can produce a slight deformation to compensate for the unevenness of the sealing surface, thereby ensuring the tightness of the seal.
[0009] As a preferred solution of the utility model, a second drain port is provided at the bottom of the liquid separation container. Since the density of oil and water is different, water usually gathers at the bottom of the liquid separation container, and the second drain port can be used to separate the water in the oil-water mixture.

[0011] As a preferred solution of the utility model, the first drain port, the second drain port and the two-phase fluid port are all provided with control switches.
[0012] As a preferred solution of the utility model, the condenser ventilation hole and the condenser return hole are both provided with an arc-shaped guide plate, and the guide plate is a hollow structure. The guide plate with a hollow structure plays a role in guiding the liquid, so that the liquid from the condensing device flows along the guide plate to the inner wall of the liquid separation container, and then flows into the bottom of the liquid separation container.
