Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing:

[0020] as attached figure 1 and 2 As shown, a three-tube air eliminator of the present invention is a vertical cylinder with round heads at both ends, and the gas-liquid ascending cylinder 6 and the liquid phase descending cylinder 8 have the same diameter, which is half of the diameter of the air eliminator cylinder 4. Installed inside the cylinder body 4 of the air eliminator, and the three are installed tangentially; the inlet 1 of the air eliminator is installed on the head at the bottom of the cylinder body 4 of the air eliminator, and the connecting pipe between it and the head is coaxial with the gas-liquid rising cylinder 6; the liquid phase outlet 2 Installed on the bottom head of the gas eliminator cylinder 4, the connecting pipe between the head and the liquid phase descending cylinder 8 is coaxial; the gas phase outlet 3 is installed on the top end of the gas e...

Abstract

The invention discloses a three-cylinder gas eliminator. The gas eliminator is a vertical cylinder with seal heads at two ends; the gas eliminator cylinder is internally provided with a gas-liquid ascending cylinder and a liquid phase descending cylinder; a gas eliminator inlet is installed at the bottom of the gas eliminator cylinder and leads to the gas-liquid ascending cylinder; a liquid phaseoutlet is installed at the bottom of the gas eliminator cylinder and leads to the liquid phase descending cylinder; a gas phase outlet is installed at the top of the gas eliminator cylinder; a float ball valve is installed on the gas phase outlet. By adopting the three-cylinder gas eliminator disclosed by the invention, small bubbles in the liquid phase are separated by using the two-time spillover effect of the small bubble-containing liquid phase caused by the situation that the internal space of a gas eliminator outer cylinder is divided by the cylinder; the structure is simple and the gaselimination effect is good.

Description

technical field [0001] The invention belongs to the technical field of oil-gas separation and flow guarantee, and in particular relates to an air eliminator. Background technique [0002] Because the mass flowmeter is highly sensitive to the bubbles or air masses contained in the liquid phase, in order to improve the measurement accuracy, an air eliminator must be installed in front of the flowmeter. [0003] The selection of the air eliminator should be carried out according to the actual needs, which is closely related to the gas content of the liquid, the instantaneous flow rate through the air eliminator, the viscosity of the medium, the working pressure, and the measurement accuracy. For occasions where the gas content in the oil is low, the viscosity is low, and the measurement accuracy is not high, a simple or auxiliary degassing device can be installed. An exhaust valve can be installed on the top of the filter, and the filter housing can be used as a container. Rem...
