Ultrahigh-pressure cyclone with normal inlet and automatic sand discharging system

Abstract

The invention relates to an ultrahigh-pressure cyclone with a normal inlet and an automatic sand discharging system. The ultrahigh-pressure cyclone comprises a cyclone cylinder, an overflow port is formed in the upper end of the cyclone cylinder, and an opening is formed in the lower end of the cyclone cylinder; a feed port is formed in the upper end of the cyclone cylinder, a feed pipe and a baffle are arranged at the feed port, the feed pipe extends in the normal direction of the cyclone cylinder, and the baffle is located on one side of a discharge port of the feed pipe and used for sealingthe discharge port of the feed pipe; and a guide plate is fixedly arranged at the upper portion in the cyclone cylinder, and the guide plate is connected with the discharge port of the feed pipe. Theultrahigh-pressure cyclone has the beneficial effects that the feed port enters the cyclone in a normal direction perpendicular mode, so that the outer contour volume of the ultrahigh-pressure cyclone is effectively reduced; due to the action of the baffle and the flow guide plate, a rotational flow field is stable, the tangential speed is relatively high, and the separation efficiency is ensured; and besides, the automatic sand discharging system is arranged below the cyclone, the backflow can be eliminated, the separation efficiency is improved, and the advantages that on-line sand discharging replaces manual high-strength sand discharging, the sand discharging risk is reduced, machining is easy, and the separation efficiency is high are achieved.

Description

technical field [0001] The invention relates to the technical field of separators, in particular to an ultra-high pressure cyclone with a normal inlet and an automatic sand discharge system. Background technique [0002] In crude oil extraction operations, due to the destruction of rock structure and improper extraction methods, a certain amount of gravel is mixed in the extracted oil and gas fluid. With the continuous deepening of crude oil extraction, the problem of sand production is becoming more and more serious. Downstream pipelines will cause serious damage to ground facilities, ground gathering and transportation and processing systems, etc., affecting the normal operation of equipment. In severe cases, it will lead to shutdown of oil fields and damage to the surrounding environment, causing immeasurable losses. [0003] In the production environment of oil fields, crude oil is often in an ultra-high pressure environment, so it is necessary to perform necessary liqui...

AI Technical Summary

Problems solved by technology

At present, the working environment of the cyclone desanding device used in the oil field is mostly in the normal pressure environment, and the working pressure is relatively low. The force is greater, and the cost of equipment materials and manufacturing is higher; at the same time, since the conventional desanding cyclone is generally composed of a single cone section, the separation time of particles in the cyclone field is less, resulting in low separation efficiency and separation accuracy, and The energy loss is also relatively large, and these devices are often difficult to meet the separation requirements of cyclone sand removal under ultra-high pressure
