Abstract

The invention belongs to the field of rotational flow filtering devices, and discloses a rotational flow filtering device and system, wherein the rotational flow filtering device comprises a cylinderbody, a filter element, a movable pup joint, an upper end cover and a lower end cover; one end of the cylinder body is connected with the upper end cover, and the other end is connected with the lowerend cover through the movable pup joint; the filter element is arranged in the cylinder body, and two ends of the filter element are connected with the cylinder body through tube plates; an air inletand a clear liquid opening are formed in the upper end cover, an air inlet valve is arranged on the air inlet, a liquid inlet is formed in the cylinder body, a liquid inlet valve is arranged on the liquid inlet, and the liquid inlet is formed in the tangential direction of the cylinder body; a slag discharging opening is formed in the lower end cover, and a slag discharging valve is arranged on the slag discharging opening. The rotational flow filtering system comprises a clear liquid pipeline, a deslagging pipeline, a circulating liquid pipeline, a liquid inlet pipeline, a compressed air pipeline, a skid-mounted base and a plurality of rotational flow filtering devices. The rapid purification effect of rotational flow precipitation debris and membrane filtration is realized; by adoptingthe design of the movable pup joint, the disassembly, the inspection and the maintenance of the device are facilitated, and the single rotational flow filtering device is of a skid-mounted structure,so that the occupied area of the device is small, and the efficiency of the device is high.

Description

Technical field [0001] The invention belongs to the field of swirling filtration devices, and relates to a swirling filtration device and system. Background technique [0002] At present, in the industrial field, membrane filtration technology generally uses a filter membrane with surface filtration performance to filter, which can make all solid particles and suspended matter in the liquid be trapped on the surface of the filter membrane. It is currently one of the most effective solid-liquid separation devices. Membrane filtration technology refers to membrane separation technology that uses pressure as the driving force, also known as membrane filtration technology. It is an advanced means of advanced water treatment. Under a certain pressure, when the original liquid flows over the membrane surface, the membrane surface is densely covered. Many small pores only allow water and small molecular substances to pass through and become permeate, while substances in the original sol...
