Vapor-liquid-solid spiral-flow type stabilized-pressure mixing conveyor

Abstract

The invention relates to a vapor-liquid-solid spiral-flow type stabilized-pressure mixing conveyor, which comprises a tank body, an oil-inlet pipe and an oil-outlet pipe, wherein the oil-inlet pipe and the tank body are orthogonally connected, the tail end of the oil-inlet pipe is bent along the circumferential direction of the tank body, an oil outlet is arranged in the bottom of the tank body, the inner end of the oil-outlet pipe extends towards the upper part in a tank to form an oil inlet, and the oil-outlet pipe extending in the tank is higher than the oil-inlet pipe. The oil-inlet pipe and the tank body are orthogonally and fixedly connected, so that the vapor-liquid-solid spiral-flow type stabilized-pressure mixing conveyor is easy to machine, the concentration of stress is reduced, the stressed situation of the integral structure of the tank body is greatly improved, and the structural stability of the tank body is improved.

Description

technical field [0001] The invention relates to oil-gas mixed transportation equipment for oil fields, in particular to a gas-liquid-solid swirl-flow stabilized pressure mixer used for the outlet of an oil-gas mixed transportation pump. Background technique [0002] In the process of oil extraction, since crude oil is collected by multi-phase media such as oil and natural gas, when it is transported to the gathering station through the mixed pump, the working conditions of the mixed pump have certain requirements on the gas content in the crude oil. When the gas-liquid is too large, that is, when the gas content in the oil is high, the mixed transport pump cannot transport normally, and it is necessary to release the excess natural gas in the oil through the pressure stabilizing buffer tank to reduce the gas content, so as to adapt to the transport work of the mixed transport pump Require. The Chinese patent No. 200620068749.0 discloses a kind of oil-gas surge tank, which i...

Problems solved by technology

The Chinese patent No. 200620068749.0 discloses a kind of oil-gas surge tank, this surge tank is provided with oil inlet and outlet tangentially on the outer peripheral surface of the tank body, in the actual work process, because the oil inlet is cut Orientation installation increases the opening ratio on the cylinder, aggravates the geometric discontinuity of the cylinder, causes stress concentration in the area near the opening, complicates the stress state of this part, and causes local high stress on the cylinder

The stress gradient is large, which seriously affects the bearing capacity of the cylinder, and this part is very easy to become the source of damage to the equipment
