Inverted conical automatic telescopic type multi-stage oil collection hydrocyclone separation device

Abstract

The invention discloses an inverted conical automatic telescopic type multi-stage oil collection hydrocyclone separation device used for solving the problem that the separation property cannot be guaranteed on the condition that the liquid inlet amount of an existing separator is not stable. The device is formed by assembling multiple conical segments with different diameters, the other conical segments are all formed by sequentially assembling different numbers of spring rings, sealing rings with different diameters and anti-shifting metal rings with different diameters except the first conical segment, and each conical segment completes cooperation through a convex hollow cylinder and a groove; and a telescopic type oil collection inverted conical unit is arranged in the device, and thetelescopic type oil collection inverted conical unit can automatically telescope along with changes of the liquid inlet amount and recycle oil not entering an overflow pipe. According to the separation device, the good oil and water separation ratio can be guaranteed, and it is guaranteed that the good separation property still can be achieved on the condition that the liquid inlet amount of the hydrocyclone separation device is not stable.

Description

technical field [0001] The invention relates to a multi-phase flow separation device applied in the fields of petroleum, chemical industry, environmental protection, metallurgy and the like under the working condition of unstable liquid inflow. Background technique [0002] Cyclone separators have been widely used in chemical industry, petroleum, electric power, environmental protection, metallurgy, water treatment, etc. It is widely used in multiple fields. During the use of the hydrocyclone, its working performance is usually evaluated by separation efficiency and particle size efficiency, and the applicability of the hydrocyclone is tested in turn. In practical application, there are many factors that will affect the separation performance of the hydrocyclone, among which the overflow split rate of the hydrocyclone is not only an important operating parameter in the cyclone separation process, but also an important performance parameter. The overflow separation rate of ...

Problems solved by technology

However, the operation process of the above two methods is more complicated, and it is difficult to adjust the diameter of the overflow pipe in time and continuously to achieve the best overflow split rate

In the actual application process, the hydrocyclone is often unable to maintain the optimal split flow rate, which leads to its low separation efficiency in many separation conditions with unstable liquid intake, which limits the application of the hydrocyclone.

Northeast Petroleum University (formerly Daqing Petroleum Institute) has applied for relevant patents for this type of device, such as patent No. 2010105565838 and other patents. The application of these existing technologies can be said to have solved most of the actual needs, but the cyclone The inner cone cannot realize real-time expansion and change according to the flow rate
