SU67246A1 - Water clarifier - Google Patents

Description

The MAIN copyright certificate No. 55622 describes a device for water clarification by means of suspension separation (by filtering water through a layer of suspended, previously precipitated sludge), consisting of a cone-diffuser, fitted in the upper part with a collector (seal) of sludge and a circular chute for clarified water.

An infusion, by the invention, provides for the connection of a cone brightener with its base with a reaction chamber, the supply of reagent solutions to a pressure pipeline ending in tangentially arranged inlets into the reaction chamber, and the supply of the device with a soothing grate above the reaction chamber. In the attached drawing of FIG. 1 shows a vertical section of the proposed device; FIG. 2 is a top view and FIG. 3 is a cross-section through the reaction chamber.

The bottom cylindrical part 2 of the device is a reaction chamber. The middle taper / with a taper angle of about 11 ° is a clarifier diffuser.

The upper cylindrical part 5 serves to create a protective layer of clarified water. The annular space 4 between the upper cylinder and the upper part of the diffuser serves to collect the sludge.

Into the lower part of the reaction chamber, nozzles 5 pass through the walls and are located in a plan tangentially.

A pipe 6 is connected to the nozzles, the water to be treated is supplied. An air separator 7 is installed on the pipe. A pipe 8 is connected to the supply of the w, to it water pipe, through which reagent solutions are fed.

The reaction chamber is separated from the clarifier by a removable restraining grill J2.

The discharge pipe 9 departs from the ring collector sludge to the slurry compactor not shown in the drawing.

At the top there is a collecting annular chute 10, from which the pipe departs // to the tank of softened water. A collection chute with a small diameter pipe is connected to the slurry compactor.

The water entering the treatment passes the air separator 7

and enters the lower part of the reaction chamber 2.

 Reagent solutions are mixed into the pipe 6 between the air separator and the reaction chamber, which are mixed with the treated water here.

Due to the supply of reagent solutions to the discharge pipeline, there is no need to lift the reagents to the top of the installation, the size of the installation building is reduced, the number of devices and pipelines is reduced, and maintenance is simplified.

The tangential entry of water into chamber 2 creates a vortex motion in it, which facilitates the movement of water and reagents and accelerates the reaction.

After chamber 2, the water passes a sedative grate, in which its rotational movement is quenched, and it rises along clarifier 1, a passage through a layer of suspended sludge.

The clarified water is collected by a collection trough 10 and discharged into the tank of dried water,

from where it comes to the distribution network.

The level of suspended sludge is limited by the top of the wall of the annular sludge collector. Excess sludge is poured through the wall and discharged into the sludge packer. Separated from the sludge compactor is discharged into the clarifier. From the sludge compactor, the compacted sludge is periodically discharged into the sewer system.

The preparation of reagent solutions is made in the usual manner.

Subject invention

The embodiment of the device for water clarification according to the author's certificate No. 55622, which means that the clarifier is connected by its base with the reaction chamber 2 to tangential inlets for reagents and water and is supplied. grids 12 located above the reaction chamber to stop the rotational movement of the liquid flowing from it.
