Overflow pipe automatic variable-diameter type cyclone separation device

Abstract

The invention provides an overflow pipe automatic variable-diameter type cyclone separation device mainly to solve the problem that since the structure of a cyclone separation device is fixed, the optimum separation ratio of the cyclone separation device can not be immediately adjusted along with the working condition. The overflow pipe automatic variable-diameter type cyclone separation device is characterized in that the cyclone separation device further comprises a diameter adjustment motor, a controller and a pressure sensing device; the pressure sensing device (4) is mounted into a device inlet pipe through threaded connection to monitor the pressure at an inlet and meanwhile synchronously transmits the measured pressure to the controller; the controller converts a pressure signal into the number of rotating laps of the diameter adjustment motor to conduct variable-diameter adjustment on a variable-diameter overflow pipe through a variable-diameter piece set; and the variable-diameter piece set is formed by common surrounding and staggering of six curved pieces, positioning is completed through an upper positioning pin, a lower positioning pin and an overflow pipe shell, and under the adjustment effect of a variable-diameter adjustment valve, all the curved pieces rotate and deviate according to a certain track to complete immediate diameter variation of the whole overflow pipe.

Description

technical field [0001] The invention relates to a separation device applied in the fields of petroleum, chemical industry, environmental protection and the like, in particular to a multi-phase flow separation device applied to the working condition of unstable liquid inflow. Background technique [0002] Nowadays, hydrocyclones have been widely used in petroleum, chemical industry, metallurgy, environmental protection, electric power, water treatment, etc. field. 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 once. In practical application, the separation performance of the hydrocyclone is affected by many factors. The overflow split rate of the hydrocyclone is an important operating parameter in the process of cyclone separation, and it is also an important performance parameter. Efficiency has a significant impact. There are two wa...

Problems solved by technology

However, the operation process of the above two methods is relatively 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.
