Description

Technical Field

[0001] The utility model relates to the technical field of oil-gas separation, in particular to an oil-gas-dust high-temperature separator. Background Art

[0002] The oil-gas separator is a device that separates the crude oil and associated natural gas produced by the oil well. The oil-gas separator is placed between the submersible centrifugal pump and the protector to separate the free gas in the well fluid from the well fluid. The liquid is sent to the submersible centrifugal pump, and the gas is released into the annular space between the oil pipe and the casing. Sometimes the separator is also used for separation, buffering, and metering of multiple phases such as oil, gas, water, and mud. There are generally three types of forms in terms of appearance: vertical, horizontal, and spherical.

[0003] The existing patent (application number 201420329695.3) discloses an oil-gas separator, which at least includes a separator shell and an air outlet pipe. The interior of the separator shell is hollow to form an oil-gas separation chamber. The lower part of the air outlet pipe is vertically placed in the oil-gas separation chamber and connected to the outside. The pipe section of the air outlet pipe located in the separator shell is provided with an annular step structure to form a stepped air outlet duct. The utility model has a simple structure, is easy to process, and occupies a small space in the engine. Compared with the traditional oil-gas separator, the oil-gas separator filter element is omitted in the product structure, which saves costs and is easy to install and maintain. A stepped air duct is adopted to allow oil and gas to enter the oil-gas separator cavity. The gas flow rate is uniform, which is conducive to gas cooling and oil-gas separation.

[0004] Most existing oil-gas separators have a gasoline separator filter element in the product structure to achieve the purpose of oil-gas filtration. However, this separator filter element is not only complex in structure, but also has a high maintenance cost, which is not conducive to universal use. Utility Model Content

[0005] The main purpose of the utility model is to provide an oil, gas and dust high temperature separator, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The oil, gas and dust high-temperature separator comprises a separator shell, an oil and gas outlet is installed at the upper end of the separator shell, a dust outlet is installed at the lower end of the separator shell, an oil and gas inlet is installed at the lower right end of the separator shell, a No. 1 jacket heating pipe is installed on the outer surface of the oil and gas inlet, a No. 2 jacket heating pipe is installed on the outer surface of the separator shell, a jacket insulation pipe is installed on the upper outer surface of the separator shell, and a heated nitrogen blowing port is installed at the upper right end of the separator shell.

[0008] Preferably, a metal filter bag and a ceramic filter bag are respectively installed on the inner wall of the separator housing. The metal filter bag can be used in a high temperature environment, is not easy to deform or melt, can withstand the impact of high temperature gas and liquid, has strong corrosion resistance, can resist the erosion of corrosive substances such as acid and alkali, has a long service life, can be reused many times, is not easy to be damaged, and is easy to clean. It only needs to be cleaned with water or detergent, will not cause pollution to the environment, and thus increases the service life of the device.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. The dust, oil and gas to be separated are introduced into the separator through the oil and gas inlet. At this time, the separator is heated as a whole through the jacket insulation pipe, No. 1 jacket heating pipe and No. 2 jacket heating pipe on the jacket on the outer surface of the separator shell, so as to heat the introduced oil and gas, which is convenient for the separation of oil, gas and dust. In addition, the heated nitrogen can also be sent into the separator through the heated nitrogen injection port, which further improves the heating effect of the separator.

[0011] 2. Through the design of metal filter bags and ceramic filter bags in the separator, the metal filter bags can be used in high temperature environments, are not easy to deform or melt, can withstand the impact of high temperature gases and liquids, have strong corrosion resistance, can resist the erosion of corrosive substances such as acids and alkalis, have a long service life, can be reused many times, are not easy to damage, and the metal filter bags are easy to clean. They only need to be cleaned with water or detergent, which will not cause pollution to the environment, thereby increasing the service life of the device. BRIEF DESCRIPTION OF THE DRAWINGS
