A fluid separation device

Abstract

The invention discloses fluid separation equipment. The fluid separation equipment comprises a main shaft, a distribution valve arranged on the main shaft, an annular hollow disc connected with the periphery of the distribution valve, a plurality of adsorption columns which are arranged on the annular hollow disc and a driving device for driving the annular hollow disc to rotate around the main shaft, wherein the distribution valve comprises a lower valve plate and an upper valve plate; the lower valve plate is fixedly connected with the main shaft; the upper valve plate is rotationally connected with the main shaft; the outer periphery of the upper valve plate is connected with the inner periphery of the annular hollow disc; the lower valve plate and the upper valve plate are provided with flow channel through holes which correspond to one another and are the same as inlets and outlets of the adsorption columns in quantity; one of the lower valve plate and the upper valve plate is provided with an annular groove and the other one of the lower valve plate and the upper valve plate is provided with a lug boss matched with the groove; the flow channel through holes penetrate through the lower valve plate and the upper valve plate through the bottom surface of the groove and the top surface of the lug boss. The groove is matched with the lug boss and the plane sealing area is greatly reduced; impurities and the like in the environment do not easily enter the distribution valve, the sealing performance of the distribution valve is improved and the influences caused by the outer environment are not caused.

Description

technical field [0001] The invention relates to the field of fluid treatment, more specifically, to a fluid separation device. Background technique [0002] As an advanced fluid separation technology, continuous fluid separation equipment has obvious advantages over traditional fixed bed and simulated moving bed adsorption separation devices. The Chinese patent No. ZL200480026164.6 discloses a device for chemical or physical treatment. The device includes a fixed frame, a turntable, a valve assembly, a motor, etc. The valve assembly and the turntable are connected on the same plane, and the valve assembly is sealed as a flat seal. The motor directly drives the turntable to rotate. Since the turntable is driven directly at the circumference, the motor drive is easy to control and facilitates driving the valve assembly to the correct position. [0003] However, in the above solution, the method in which the valve assembly is directly installed on the turntable makes the desi...
