Separating device for dissolved gas in oil

Abstract

The invention discloses a separating device for dissolved gas in oil. The separating device comprises an oil-gas separation chamber, a gas pre-enrichment chamber, a centrifugation degasification mechanism, a mini-type vacuum pump and a control circuit, wherein the gas pre-enrichment chamber is mounted at the top end of the oil-gas separation chamber; the top end of the gas pre-enrichment chamber is connected with a two-way electromagnetic valve and the mini-type vacuum pump; the mini-type vacuum pump is connected with a purification cavity through a third three-way electromagnetic valve; a pressure sensor is further connected onto the gas pre-enrichment chamber; a temperature sensor, a liquid level meter and the centrifugation degasification mechanism are mounted on the oil-gas separation chamber; the centrifugation degasification mechanism is connected with a mini-type oil pump through a second three-way electromagnetic valve; a first three-way electromagnetic valve is connected between the mini-type oil pump and the oil-gas separation chamber. According to the invention, the oil-gas separating speed is obviously increased, so that all units and components of the device are efficiently and reasonably utilized, the problems that the oil-gas separation speed is low and the separation is not stable in the conventional equipment are radically solved, the device redundancy is reduced to the maximum extent, and the operation reliability is improved.

Description

technical field [0001] The invention relates to the field of separation equipment, in particular to a separation device for dissolved gas in oil. Background technique [0002] At present, the separation methods of dissolved gas in oil mainly include air blowing in oil, vacuum magnetic stirring, membrane penetration, water bath heating volatilization, ultrasonic excitation and other methods. These methods generally have problems such as slow separation of oil and gas and low separation efficiency. The fastest one needs about 45 minutes to separate the amount of gas that can be used for measurement, and the slowest one takes 10 hours or even longer to separate enough gas. Contents of the invention [0003] The object of the present invention is to provide an oil-dissolved gas separation device to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [...
