Example 8. In order to ensure the mobility of the installation of air purification, all of its structural elements are placed on a trolley.

The implementation of the structural elements of the claimed invention is not limited to the above examples.

The inventive installation of air purification works mainly in two modes.

In both modes, the storage tank (2) is completely or partially filled with liquid, mainly water.

In the first mode (bubbling mode), the first locking device (6) is closed, the second (10) and third (11) locking devices are open. Shut-off devices at the inlet and outlet of the water pump (4), if any, are closed.

Contaminated air is forced into the bubbler pipe (7) through the second branch (16) of the inlet pipe (1). Passing through the perforation of the bubble tube (7) located in the bottom region of the storage tank (2), the air is divided into small bubbles, forming a bubble layer. With the movement of air bubbles in the bubble layer, a large interfacial contact surface of the air bubbles with the liquid is created. This creates favorable conditions for the absorption of contaminants by the liquid. The bubble layer is not uniform in height. Above the perforation of the bubbler pipe (7), when a certain flow rate is reached, gas jets form, and above them a bubble layer. The latter ends with a layer of foam. As air bubbles rise to the surface, their volume increases, due to a decrease in pressure. Thus, bubble destruction occurs in the foam layer. This is accompanied by the release of droplets and the release of moist, cleaned from large air pollution.

Wet purified air enters through the moist air pipe (8) into the separator (3). In the separator (3), air is cleaned of moisture and small impurities. liquid and contaminants separated from the air are transported to the drain pipe (9) and then to the bottom of the storage tank (2).

The cleaned air stream is directed to the outlet pipe (13).

In the second mode (irrigation mode), the first locking device (6) is open, the second (10) and third (11) locking devices are closed. The locking devices at the inlet and outlet of the water pump (4), if any, are open. Through the water inlet from the storage tank (2), liquid enters the water pump inlet (4), which is pumped from its outlet to the sprinkler (5).

Contaminated air is forced into the first branch (15) of the inlet pipe (1), passing through which it is irrigated with drops of liquid from the sprinkler (5). Drops of liquid trap particles of impurities and hold them.

The air stream with enlarged and fluidized particles of pollution enters the separator (3). In the separator (3), air is cleaned of moisture and contaminants. The liquid and contaminants separated from the air are transported to the drain pipe (9) and then to the bottom of the storage tank (2).

The cleaned air stream is sent to the outlet pipe (13).

In addition to the two main operating modes described above, the air purification unit can also be used in combined mode. In this case, the storage tank (2) is partially filled with liquid, the first locking device (6) is closed, the second (10) and third (11) locking devices are opened. Locking devices at the inlet and outlet of the water pump (4), if any, are opened.

Through the water inlet from the storage tank (2), liquid enters the water pump inlet (4), which is pumped from its outlet to the sprinkler (5).

Contaminated air is forced into the bubbler pipe (7) through the second branch (16) of the inlet pipe (1). Wet purified air enters through the humid air pipe (8) into the separator (3), and along the way it is irrigated with drops of liquid from the sprinkler (5).

In the separator (3), air is cleaned of moisture and small impurities. The liquid and contaminants separated from the air are transported to the drainage ^“ pipe ^” (9) G and then to the bottom of the storage tank (2). The cleaned air stream is directed to the outlet pipe (13).

Thus, in the inventive installation of air purification, the claimed technical result: "expanding the range of conditions for the use of the device" is achieved due to the fact that the installation of air purification contains an inlet pipe, a storage tank, a separator, a water pump and a sprinkler. At this separator contains an inlet, outlet and drain pipe, and the inlet pipe of the separator is connected to the first branch of the inlet pipe, which houses the sprinkler connected to the outlet of the water pump, the input of which is connected to the storage tank. In this case, the first branch of the inlet pipe is provided with a first locking device. At the same time, the storage tank contains a bubbler pipe, an outlet pipe for moist air and a drainage pipe. In this case, the input of the bubbler pipe is brought out, and a part of the bubbler pipe from the opposite end to the input is located in the bottom region of the storage tank and is provided with perforation. In this case, the outlet pipe of the moist air is equipped with a second locking device and is connected to the inlet pipe of the separator. In this case, the first end of the drainage pipe is brought out, and the second end is placed inside the storage tank below the bubbler pipe. In this case, the inlet pipe contains a second branch equipped with a third locking device and connected to the inlet of the bubbler pipe. In this case, the drain pipe of the separator is connected to the first end of the drainage pipe.

In this case, the operation of the inventive installation in the bubbling mode allows you to refuse to use the pump when mixing media. This reduces the energy consumption of the installation. However, bubbling does not significantly reduce the size of the bubbles, which is achieved when the inventive installation in the modes using irrigation. Moreover, a decrease in droplet size increases the total contact area between the media. This in turn improves the quality of air purification.

Industrial applicability.

The inventor made a prototype of the claimed installation of air purification, tests of which confirmed the achievement of the technical result.

The claimed invention is implemented using _^ industrially produced devices and materials, can be manufactured at an industrial enterprise and will find wide application in the field of air purification.
