Description

The utility model relates to devices for purifying industrial wastewater from pollutants and can be used in engineering, instrument-making, and energy industries to remove pollutants from industrial effluents.

Known devices for cleaning working fluids using centrifugal forces. For example, (Prince AS Timonin “Engineering and Environmental Handbook.” Vol. 2. - Kaluga: published by N. Bochkareva, 2003 - 884 pp.), The design of the pressure hydrocyclone is given (Fig. 1. 49, 488 pages). ) Such devices are intended only for cleaning from large particles of pollutants and is accompanied by significant wear on the walls of the chamber. A device is known in which, to increase the cleaning efficiency, a combination of centrifugal cleaning with thin-layer sedimentation is used (Utility Model Patent No. 110284, Bull. No. 32, 2011), however, the problem of abrasive wear of the walls remains. A device according to the invention is known No. 1745350 (B04C 1/00, a.u. Bull. No. 25, 1992) in which, to reduce the abrasive wear of the walls of the spiral channel, slots are made. This device is taken by us as a prototype. The disadvantages of the prototype are as follows: the slots on the walls of the spiral channel are not regulated in the direction of flow, although the accumulation of sludge at the channel wall will depend on the flow rate and the initial concentration of the pollutant, which can vary significantly. From this, the overall performance of the device will vary over a wide range. Another disadvantage of the prototype is the limited use of the type and composition of pollutants. In addition, the tubular shape of the spiral channel does not provide complete removal of sludge in the slots and part of the sludge will remain in the lower sector of the channel.

Most industrial wastewater consists of pollutants in the form of suspended solids, and dissolved components. The prototype device only cleans suspended solids, and other devices with physicochemical methods must be used to remove dissolved components, which significantly increases the cost of cleaning.

The technical result, the achievement of which the proposed device is aimed at, increase the cleaning efficiency, expand the range of use and reduce economic costs. This goal is achieved by the fact that in the separator containing a spiral channel with a device for diverting a divided stream in the form of slots on the outside of the spiral and bending the channel wall inward in a direction opposite to the direction of flow, there is a movable chamber at the outlet of the outlet pipe, filled with ion-exchange granules and equipped regeneration device, moreover, the slots on the outside of the spiral are movable with regulation of the location on the spiral wall, and the spiral forming the separator has rectangular cross section and is formed as a cone with the apex facing outlet pipes downwards. The proposed device is presented on

The proposed device is a spiral casing 1, made in the form of a cone, facing the top down. In the upper part of the housing there is a pipe for supplying purified water 2. On the outer walls of the housing 1 there are slots 14 equipped with reflectors 15 mounted on the far wall of the slots 14 in the direction of fluid flow. The slots 14 together with the reflectors 15 are made moving along the spiral of the casing 1 and together with the casing of the sludge removal tank 3 are connected to the sludge collection chamber 13, which has a sludge drain pipe 12. At the bottom of the spiral casing 1 there is a pipe for draining water from the separator 4. The pipe 4 enters in the annular visor 6, located on the movable chamber 7. Inside the chamber 7, between two non-failing nets 9 there are bulk granules of ion exchanger 11. On the same axis as the nozzle 4, a funnel with a nozzle for removing purified water 10 is installed under the chamber azom, on the same axis with the pipe 5 for supplying regeneration medium, under the camera 7 is funnel with a nozzle 8 for discharging the regenerating environment. To rotate the chamber 7 in a horizontal plane there is a drive (not shown).

The device operates as follows. Source wastewater contaminated with suspended and dissolved pollutants through the inlet pipe 2 enters the spiral housing 1.

As you move in the spiral channel, due to the action of centrifugal forces, suspended particles are discarded from the outer wall of the spiral and, as they accumulate, reaching the reflectors 15 are discharged through the slots 14, through the casings 3 they enter the sludge removal chamber 13 and are removed through the pipe 12.

As the fluid moves along the spiral channel, the centrifugal force increases, and medium and small particles are discarded to the channel wall, which are removed through the slots 14 located on the lower turns of the spiral case. Then, through the appropriate housings, they enter the chamber 13 and are discharged through the nozzle 12. The liquid purified from suspended particles through the nozzle 4 enters the visor 14 and begins to spill through the bulk layer of ion exchanger 11. Ionite extracts dissolved pollutants from water through physical or chemical processes substances and purified water through the funnel 10 and the pipe enters the consumer. As water passes through the layer of ion exchanger, it is saturated with a pollutant and loses its absorption properties. To restore the properties of the ion exchanger, it must be regenerated. For regeneration, the ion exchanger is moved together with the movable chamber 7 with a special drive (not shown) to the area of the nozzle 5, where it is processed by the regenerating composition. When using ion exchangers, acidic (for cateonites) or alkaline compounds (for anion exchangers) are used. After regeneration, the ion exchanger layer 11 again moves together with the chamber 7 into the liquid supply zone from the nozzle 4. The cleaning and regeneration process can be carried out continuously, selecting the speed of movement of the chamber 7, depending on the initial concentration of the pollutant and the saturation curve of the selected sorbent. Also, depending on the type and concentration of suspended solids, the location of slots 14 is adjusted along the length of the spiral channel.

Thus, the proposed device improves the efficiency of industrial wastewater treatment, extends the range of use reduces the economic costs of treatment.
