Description

The invention relates to the treatment of drinking and waste waters, and can be used to destroy bacterial flora and remove solutes.

The purpose of the invention is to increase cleaning performance, reduce costs and improve operating conditions.

The drawing shows a device for the purification of drinking and waste water.

The device for purifying drinking and waste waters contains pipelines 1 and 2 for supplying and discharging the liquid to be purified, a sealed chamber 3 filled with the liquid being cleaned to form a free space 4, and a vacuum pump 5 connected by the inlet pipe 6 to the free space 4 of the chamber. The device also contains a drive valve 7, an outlet pipe 8 with a check valve 9 connected to the chamber in the lower part and a receiver 10 filled with compressed oxygen, which is connected to the input of the drive valve 7 by pipe 11 and is connected to the outlet of the vacuum pump through a two-way valve 13, which in the working position connects the vacuum pump with the receiver, and in the auxiliary - with the atmosphere. Pipelines 1 and 2 are equipped with stop valves 14 and 15.

The hermetic chamber 3 has a collector 6 located at the bottom with outlet nozzles 17 for supplying oxygen to water, a drain pipe 18 for solid contaminants, equipped with a shut-off valve 19, and a drain pipe for pop-up contaminants 20, equipped with a shut-off valve 21. For the convenience of collecting solid loads The bottom 22 of the chamber 3 is inclined and contains a collection cup 23 to which the drain pipe 18 is connected. The drain pipe 20 for draining soils that float to the surface of the water with oxygen bubbles, connect It is connected to the chamber at the upper liquid layers, the pipelines 1 and 2 of the flow of purified water are connected to the chamber above the location of the collector 16. The pipeline 6 of the vacuum pump is connected to the chamber in the free space of the chamber, and the pipeline 8 of the drive valve is connected to the chamber at the bottom and is connected with manifold pipe 24. The check valve 9 is designed for

preventing the filling of the pipeline 8 with water after the supply of oxygen. The camera is equipped with a cover 25.

The vacuum pump 5 is designed to suck gases and vapors from the free space 4 and create a vacuum in the chamber, during which cavitation bubbles are released in the water. If the vacuum pump is operated after opening the lid of the chamber 25, then first the valve 13 ejects air from the free space 4 of the chamber to the atmosphere, and then the valve 13 is set to the working position to connect the outlet of the vacuum pump 5 to the receiver 10 through pipeline 12 .

The receiver 10 is a sealed container filled with compressed oxygen, and is intended to supply oxygen to the chamber and receive it after suction with a vacuum pump from the chamber. The receiver is provided with a pipe 26 with a valve 27 for supplying compressed oxygen from an external source to the receiver.

The drive valve 7 contains a spring loaded spring 28 spool 29, which overlaps or opens the connection of the inlet 30 and outlet 31 of the orifices, which are connected respectively to the pipes 11 and 8. In the open position, the valve 7 connects the receiver 10 to the chamber 3 for supplying oxygen to it. To move the valve spool 29, an actuating cam 32 is mounted. The lid of the chamber 25 is provided with a pipe 33 with a valve 34 for air inlet and outlet.

The device works as follows.

First, the device is prepared for operation. After opening the valves 14 and 34, the chamber 3 is filled with the liquid to be cleaned to form the free space 4, after which the valves 14 and 34 close, the valve 13 is set to the auxiliary position and the vacuum pump 5 is turned on. The air from the free space 4 is sucked and released into the atmosphere. After a vacuum is reached, cavitation bubbles are released in the liquid, i.e. the liquid boils, the valve 13 is installed in the working position. The camera is ready to go.

The valve actuator 7 is turned on. The valve moves and establishes a connection between pipelines 8 and 11, compressed oxygen through pipelines 8, 11 and 24, squeezing the check valve 9, enters the manifold 16, from where it passes through the nozzles 17 into the chamber liquid.

Passing through the liquid, oxygen enters the free space of 4 chambers. As a result of the increase in pressure in the chamber, cavitation bubbles collapse (cavitation). Then, the actuating valve 7 is closed, the vacuum pump 5 sucks the oxygen into the receiver 10, boils the liquid with evolution of cavitation bubbles and again supplies oxygen through the liquid to the chamber, etc. The collapse of the bubbles is accompanied by the appearance of shock jets of high
