Abstract

The hydrocyclone is intended for the separation of liquid and solid phases and can be used in water recycling systems of industrial enterprises, as well as for purifying wastewater from mineral suspended matter in various industries. The purpose of the invention is to simplify the design of the device while maintaining the effectiveness of wastewater treatment. The hydrocyclone contains a cylindrical housing (K) 1, pipes for supplying the source 2 and removal of purified water 3, pipe for sludge removal (PS) 4, a set of cylinders (C) 5 installed concentric with the central axis of the hydrocyclone, on the side surface of which laid in adjacent cylinders with an offset of 180 °. Peripheral C 5 is made solid. The original fluid through nozzle 2 is supplied to K 1 and is twisted. The solid particles are thrown against the wall of K 1 and discharged through PN 4. The clarified liquid rotates within C 5, which form between each other thin-layer zones of centrifugal separation. Contaminant particles move along the periphery to the periphery and are also thrown to the wall K 1 and then discharged through PN 4. 2 sludge. to

Description

The invention relates to the purification of liquids from suspended solids and can be used in water recycling systems of enterprises in various industries.

The purpose of the invention is to simplify the design of the device while maintaining the efficiency of wastewater treatment.

In FIG. 1 shows a hydrocyclone, a longitudinal section; in FIG. 2 is a section AA in FIG. 1.

The hydrocyclone contains a cylinder-conical housing 1, nozzles for supplying the initial 2 and discharge of purified water 3, a nozzle 4 for discharging sludge, a set of cylinders 5 installed concentrically relative to the central axis, the height of which decreases monotonically from the center to the periphery. On the lateral surface of the cylinders 5, along their entire height, vertical slots 6 are made, which are directed in opposite directions in adjacent cylinders (with an offset of 180 °). The peripheral cylinder is made integral.

The hydrocyclone works as follows.

The initial fluid through the pipe 2 tangentially enters the housing 1, where it rotates relative to the central axis, while the particles of the solid phase are discarded by the action of centrifugal forces on the walls of the housing 1 of the hydrocyclone, slide into its lower conical part and are discharged from the hydrocyclone through the pipe 4. In the steady state of operation of the hydrocyclone, the clarified liquid rotates inside the cylinders 5, which form thin-layer centrifugal separation zones, and additional clarification of water from pollution particles occurs.

Primary clarification of water occurs in the peripheral part of the hydrocyclone. The particles of contaminants are discarded under the action of centrifugal forces on the walls of the cylinders 5, the fluid flow gradually moves to the cracks, breaking the lower part of the cylinders 5. Thus, under the action of centrifugal forces, the particles of contaminants are gradually transported to the peripheral part of the hydrocyclone, discarded on the walls of the housing 1 and together with the main stream pollution slide into the lower conical part of the hydrocyclone. Due to the fact that the peripheral cylinder does not have a slit 6 (the initial fluid stream with the maximum concentration of contaminants enters this part of the hydrocyclone), which are directed in opposite directions in other adjacent cylinders 5, the possibility of contaminants from entering the peripheral part of the hydrocyclone to its central the part where the clarified fluid stream rotates, and therefore the efficiency of wastewater treatment while simplifying the design of the hydrocyclone, in particular its vertical partition, is maintained, oraya in the known device is curved in a spiral.
