Abstract

The invention relates to structures and devices for treating oil-containing water and can be used to purify both industrial and domestic wastewater. The purpose of the invention is to increase the efficiency of water purification from emulsified petroleum products. A device for purifying water from emulsified petroleum products comprises a housing with pipes for supplying contaminated water and discharging clarified water and separated petroleum products. The lower part of the body is made in the form of a cone and provided with a pipe with a valve for discharging the settled sludge. In the center of the housing there is a drive device with a worm shaft, through which the carriage moves with the emitters of sound that is placed on it. A perforated partition is placed in the upper part of the device to separate oil products from water.

Description

The invention relates to the purification of oily water, namely to structures and devices for purifying water from highly dispersed and emulsified oily substances, and can be used to purify both industrial and domestic wastewater.

The purpose of the invention is to increase the efficiency of water purification from emulsified petroleum products.

FIG. 1 shows a diagram of the device; in fig. 2 - section AA on FIG. one.

The device comprises a housing 1 with pipes for supplying contaminated water 2 and a drain 3 for clarified water, pipes 4 for withdrawing oil products separated from water. The lower part of the device is made in the form of a cone 5 and is provided with a pipe with a valve 6 for inserting the settled sludge. In the center of the housing there is a drive unit 7 with a vertical worm 8, along which the carriage 9 moves with the ultrasound emitters 10 placed on it. In the upper part of the device, there is a perforated partition 11 for separating oil products from water and 4 for removing separated oil products. Pipe 2 inlet

water located at the bottom of the housing.

The device works as follows.

Water containing emulsified oil products enters pipe 2 through pipe 2. Tangentially, the flow of water rises tangentially into the upper hour of the device. Synchronously with a speed equal to the speed of water rise, in the vertical plane, along the worm shaft 8, the carriage 9 moves with ultrasonic radiators 10 placed on it. Radiating ultrasonic waves are reflected from the inner surface of the housing 1 and transmitted in the opposite direction. The overlap of forward and reverse waves of the same length in the volume of purified water by the effect wave, which is characterized by the formation of zones of reduced and increased pressure. The microparticles of emulsified petroleum products, moving into the zone of reduced pressure, coalesce and form large droplets. Thanks to that

creates

the effect is one hundred

the ultrasound emitter moves up synchronously with a certain volume of water, then the emulsified oils are almost completely removed from the water. Drops of petroleum products rise to a perforated partition 11, pass through it and are removed through pipe A for further recycling. Purified water is removed through pipe 3. The carriage with radiators is moved back down and the cycle of oil recovery is repeated. Mineral particles are deposited in the conical space, from where they are periodically removed through valve 6. Thus, this device can be used for all types of polluted water, with

The advantages of the proposed device in comparison with the known one is that the ultrasound emitter is not contaminated with suspended solids, and the efficiency of extraction of petroleum products remains constant over time. The proposed device makes it possible to create the effect of a standing wave in the entire volume of water and almost completely remove emulsified oil products. In addition, the device allows for the removal of suspended solids, which is absent in known devices. When using known devices, it is necessary to pre-purify oily water from suspended solids, which leads to an increase in the cost of water purification and narrows the scope of application of known devices.

The application of the proposed device increases the effect of clarification of oil-containing water, allows to obtain a cleaner oil.
