An adjustment device for improving the separation efficiency of a hydrocyclone

Abstract

An adjustment method and device for improving the separation efficiency of a cyclone. The main purpose is to solve the problem that the use of a fixed size cyclone is difficult to adapt to the field conditions of the oil field and other industries where the processing capacity changes, resulting in a greatly reduced separation efficiency. It is characterized in that: a device that can change the inlet area of ​​the cyclone is installed at the inlet of the cyclone. When the processing capacity is low in the process, the area of ​​the inlet of the cyclone is reduced to increase the inlet velocity. When it is high, the inlet area is increased in turn to reduce the inlet velocity, so that the cyclone can achieve the purpose of efficient separation under the condition of different processing capacity; the device that can change the inlet area of ​​the cyclone is related to the cyclone The area adjustment component at the inlet of the cyclone and the power component are composed of two parts, wherein the area adjustment component is arranged inside the cyclone, and the power component is arranged outside the cyclone.

Description

technical field [0001] The invention relates to an adjustment method and device for improving the separation efficiency of a hydrocyclone used in the field of hydrocyclone separation. Background technique [0002] At present, the technology of domestic hydrocyclones is relatively mature, and the separation effect of oil and water is obvious, but there is a problem in the separation of oil and water or solid-liquid and other media: the flow rate (processing capacity) is too small, the speed is low, and the efficiency is low; the flow rate is too high. The effect of large shear makes the particles in the flow field smaller and makes it difficult to separate. Therefore, the flow curve of the cyclone will have a high-efficiency flow area. Although the efficiency is very high, this high-efficiency area is relatively narrow. For example, the flow rate of the designed cyclone is 4m 3 / h, then the high-efficiency zone is at 4 m 3 / h up and down about 20% range. In practical appl...

Problems solved by technology

[0002] At present, the technology of domestic hydrocyclones is relatively mature, and the separation effect of oil and water is obvious, but there is a problem in the separation of oil and water or solid-liquid and other media: the flow rate (processing capacity) is too small, the speed is low, and the efficiency is low; the flow rate is too high. The effect of large shear makes the particles in the flow field smaller and makes it difficult to separate

However, at the beginning of the design of these cyclones, it is necessary to set the suitable processing capacity of the cyclone. When the site conditions change, once the predetermined processing value cannot be reached, the separation efficiency will be greatly reduced.
