Description

Technical Field

[0001] The utility model relates to the technical field of oil-gas separators, in particular to a small-volume modular oil-gas separator. Background Art

[0002] Oil-gas separators are usually installed and connected to the transmission pipeline. Their main function is to separate the oil-water mixture before or after it passes through, so as to effectively treat and recover the oil and water. Nowadays, oil-gas separators are usually used to treat oil-water mixtures. Their working principle mainly relies on gravity separation. This equipment uses the density difference of liquids to make the oil and water settle or float inside the equipment, thereby achieving effective separation of oil and water.

[0003] However, common oil-gas separators are usually a whole unit that separates the oil-water mixture that enters it. When such oil-gas separators have abnormalities at their oil or water outlets, they need to stop working as a whole for maintenance, which affects the separation work and reduces the separation efficiency. In view of this, we propose a small-volume modular oil-gas separator. Utility Model Content

[0004] The utility model aims to provide a small-volume modular oil-gas separator in view of the problems existing in the background technology.

[0005] The technical solution of the utility model is as follows: a small-volume modular oil-gas separator comprises a first container, a second solenoid valve for guiding a medium is mounted on one side wall of the first container, a drainage assembly for draining oil and water is arranged at the outlet ends of the two second solenoid valves, a positioning piece for fixing the auxiliary drainage assembly is symmetrically mounted on one side wall of the first container, a drainage assembly for supporting the drainage assembly is symmetrically mounted on one side wall of the first container, a first capacitance sensor for detecting oil and water is mounted on an inner wall on one side of the first container, a second capacitance sensor for detecting oil and water is mounted on the inner wall on the other side of the first container, a partition for separating is arranged in the first container, and a first solenoid valve is mounted on the bottom wall of the first container and is installed in a third through hole.

[0006] Preferably, inner walls on both sides of the first container are provided with built-in grooves, and the first capacitive sensor and the second capacitive sensor are respectively installed in the built-in grooves corresponding in position.

[0007] Preferably, a first through hole and a second through hole are formed in the top wall of the first container, and a liquid inlet pipe and an automatic exhaust valve are installed in the first through hole and the second through hole respectively.

[0008] Preferably, a third through hole is formed on the bottom wall of the first container, and the first solenoid valve is installed in the third through hole.

[0009] Preferably, the two second solenoid valves are used for draining oil and draining water, respectively, and the two sets of drainage components are also used for draining oil and draining water, respectively.

[0010] Preferably, the drainage assembly includes a second container, a sealing plug-in is installed at the inlet of the second container, a thread is arranged on the groove wall of the sealing plug-in, a thread groove is arranged on the groove wall of the positioning member, and the sealing plug-in is connected to the positioning member through threads.

[0011] Preferably, the outlet of the second container is connected with a drain pipe.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] The utility model introduces oil into a first container through a conveying device to separate oil and water. A first solenoid valve provided at the bottom of the first container can discharge the initially separated water, and under the action of a partition, the floating oil can be introduced into the space on the other side of the partition, and after a second separation, the oil is discharged from the second oil discharge container. At the same time, the water separated for the second time is discharged through the second oil discharge container, thereby further improving the separation effect. If an abnormality occurs at the oil discharge and maintenance is required, the second oil discharge container can be disassembled in a targeted manner according to needs, thereby making the second oil discharge container in a working state, and the oil discharge port can be closed under the action of the second oil discharge solenoid valve, so that it does not affect the separation work. Since the second oil discharge container is separately arranged from the second water discharge container and is manufactured in a small volume, small volume modular separation is achieved, thereby providing convenience for the separation work.
