Inside the body of the humidifier is a pan with water and a humidifying drum, which is driven by a drive. The drum consists of a plurality of discs made of easily wettable material. Discs rotate partially immersed in water. A built-in fan blows the humidifying drum perpendicular to the axis of rotation of the drum. This humidifier is not a channel humidifier and cannot be used in distributed humidification systems serving several rooms at once. It is installed in a serviced room and maintains humidity only in this room. This industrial humidifier PRO-4000p has the following disadvantages:

-large dimensions;

large mass;

the inability to use in duct humidifiers due to the low productivity of humidification;

the impossibility of regulating the air humidity at the outlet of the humidifier, while the air humidity is only controlled in the humidified room and is achieved by passing the air in the room through the humidifier several times. Known channel humidifier evaporative type Breezart Humi (http://www.breezart.ru/catalog/humidifier/) 08/15/2004, which uses water-absorbing and air-permeable honeycomb material with a large area of the evaporating surface (GLassPad manufactured by NuTes (https: //hutek.com/). The evaporating surface is 460 m2 per 1 m3 of material. The humidifier evaporator, which is a cassette with honeycomb material GLassPad, is stationary in the humidifier body and is humidified by water from the pan using a circulation pump. Regulation of air humidity, p passing through the humidifier, occurs with the help of additional heating of the air with a pre-heater at the inlet and a post-heater at the outlet.

The Breezart Humi evaporative duct humidifier has the following disadvantages:

- low reliability and maintainability due to the complexity of the design;

- the need to use a droplet eliminator;

- Uncontrolled humidification of the evaporator from above using a circulation pump;

- the need to use a pre-heater and post-heater to control air humidity;

- regulation in a narrow range of humidity and air flow;

- large inertia and, as a result, a large time for the humidifier to reach a given humidity;

- large dimensions;

- high price;

- high noise level.

The purpose of the invention.

The aim of the invention is to increase the efficiency of air humidification in channel air humidifiers by increasing the range of humidity control while expanding the range of air flow and controlled air humidification in accordance with the specified humidity parameters, as well as optimizing the process of air humidification in channel humidifiers by simplifying, reducing the size and cost designs, exceptions for pre-heater and post-heater, circulation pump for humidification of the evaporator, droplet eliminator and noise reduction.

KUV consists of a housing 1 with input 2 and output 3 flanges. Inside the housing 1 there is an input carrier plate 4 and an output carrier plate 5 with openings for air passage. The outer race of bearings 6 is fixed on the plates. The inlet cover 7 and the outlet cover 8 have rigidly mounted shafts 9, which enter the inner race of the bearings 6 and allow the evaporator housing to rotate 10. Both covers are made with holes for air passage and are tightly mounted on the evaporator housing 10 The evaporator consists of the body of the evaporator 10 and the honeycomb material 11. The body of the evaporator 10 is made in the form of a hollow cylinder. Cellular material 11 is a water-absorbing and air-permeable honeycomb material with a large evaporating surface area (GLassPad, CelPad manufactured by HuTec (https://hutek.com/), with an evaporating surface of 460 m2 per 1 m3 of material or other similar materials). If the humidifier material is anisotropic, then to increase the uniformity of moistening, it is necessary to use several layers of honeycomb material 11 with each layer rotating about an axis of the evaporator body 10 relative to the adjacent layer by a certain angle (the figure shows a humidifier consisting of 4 layers, each of which is rotated sequentially by an angle of 45 degrees around the axis of the body of the evaporator 10 relative to the previous layer in one direction. Cellular material 11 is wetted by rotation of the evaporator with water poured into a pan 12 to ur water ram 13. In case of emergency level exceeding, water is poured into the overflow tank 14 and is discharged into the sewer through the overflow pipe 15. The electric actuator 16 rotates the evaporator through the gear train.The water level 13 in the sump 12 is controlled by a float 17. The water is added to the sump 12 through the pipe water supply 18 and is controlled by a water supply valve 19. The water is drained from the pan 12 through a water discharge pipe 20 and is controlled by a water drain valve 21.

Principle of operation.

In humidification mode, dry air enters through the inlet flange 2 of the CCU body 1 (the direction of air movement is indicated by an arrow in Fig. 1), then passes through the holes in the inlet carrier plate 4 and the holes in the inlet cover 7 and enters the cellular material 11. Cellular material 11 when the body of the evaporator 10 is rotated, it is moistened with water by immersing the evaporator in water in the pan 12. Dry air passing through the cell material 11 moistened with water with a large evaporating surface is moistened, then passes through the openings in the outlet roofs e 8, passes through the holes in the outlet 5 and the carrier plate passing through the outlet flange 3 of the body 1 is output from the BCCH. The evaporator rotates around its axis due to gearing from the electric drive 16. The inlet cover 7 and the output cover 8 have rigidly mounted shafts 9 that enter the inner race of bearings 6 located on the inlet carrier plate 4 and the outlet carrier plate 5, and provide rotation of the evaporator around the axis of the evaporator body 10. Automatic adding water to the pan 12 is carried out through the water supply pipe 18 and is controlled by the water supply valve 19. The control of the water level 13 is carried out by the float 17. Humidity adjustment air is carried out by changing the rotation speed of the evaporator, alternating periods of rotation of the evaporator and stop, as well as by changing the water level 13 in the pan 12. When the humidity at the output of the CCW is less than the lower set value, the evaporator starts to rotate. Since the evaporator is immersed in water, the rotation of the evaporator increases the volume of moistened honeycomb material 11, which leads to an increase in the moistened surface of the honeycomb material 11, which is blown by air passing through the CCF. The humidity at the output of the HFM begins to increase. When the air humidity becomes higher than the upper set value, the rotation of the evaporator stops, which leads to a gradual decrease in the area of the moistened surface of the honeycomb material 11 due to the evaporation of water and, accordingly, to a decrease in the air humidity at the output of the CCF. If it is necessary to significantly increase the humidity of the air passing through the CCF, in addition to the rotation of the evaporator, there is a gradual increase in the water level 13 in the pan 12 by adding water through the water supply pipe 18 when opening the water supply valve 19, which leads to an additional increase in the wetted surface of the honeycomb material 11 during rotation evaporator. Upon reaching the necessary indicators of air humidity, topping up of water stops. And vice versa, if it is necessary to significantly reduce the amount of moisture evaporated by the evaporator, in addition to stopping the rotation of the evaporator, there is a decrease in the water level 13 in the pan 12 by draining the water through the water drain pipe 20 when the water drain valve 21 is opened. In case of emergency exceeding the maximum water level in the pan 12, water begins to overflow into the overflow tank 14 and is removed from it through the overflow pipe 15 into the sewer.
