SUBSTANCE: invention is intended for gas drying, cleaning and heat exchanging and may be used for air ventilation and conditioning. Device is provided with shell, rotor with set of disks fixed to hollow shaft and a set of heat exchanging tubes arranged circumferentially along set of disks but at some distance from shaft, inlet and outlet nozzles. At full circle, rotor disk edges are represented in the form of blades directed either in parallel to disk radius or at ϕ - angle to disk radius and deflected to inter-disk space at tilting angle 0<α<180°. Blades are flat or deflected lengthwise and edgewise with permanent thickness or profiled shape in cross section. Distance b between disks is selected based on the following condition λ>1, λ=b (ω/ν)0.5, where b - distance between dicks; ν - cinematic viscosity of gas; ω -cyclic rotation frequency of rotor. Rotor in shell is installed with clearance d, defined by condition 0<d/R<0.5, where d - clearance between shell and rotor disks; R - disk radius.

The invention relates to ventilation and air conditioning and can be used in devices air handling systems installed in buildings and structures for various purposes, in particular in residential and public buildings, livestock facilities for the drying gas, including air, with its simultaneous removal of water-soluble gases, and also for purification of other gases and heat transfer, including heat exchange with gas at low pressure.
It is known device the Rotor for pump /1/containing shell, a rotor with a package of disks mounted on a shaft at some distance from each other, and inlet and outlet nozzles. On each rotor disc evenly spaced around the circumference of the completed blade located at some distance from the outer edge of the disk.
The disadvantage of this device is that such a rotor for a pump cannot be effectively used for heat exchange, drying gas, with its simultaneous removal of water-soluble gases, as it has a low value of heat transfer coefficient.
A prototype of the selected device for dewatering, gas cleaning and heat transfer /2/, comprising a housing, a rotor with drive package, mounted on the hollow shaft with a channel for heat transfer, as well as inlet and outlet. The channel of the heat exchange performed in the form of a set of Teploobmennik the x tubes passing through the entire stack of disks and located around at some distance from the hollow shaft, coaxial to its axis and communicating with the hollow shaft by means of radially arranged channels, forming a closed channel heat transfer.
The disadvantage of the prototype is the low value of coefficient of heat transfer from the disk rotor for a gas at low (1-40 Torr) pressure.
The objective of the proposed technical solution is to increase the performance of the device for mass flow and heat transfer, especially at low gas pressure, as well as improving the quality of the cleaning gas.
The problem is solved due to the fact that the device for draining, gas cleaning and heat transfer includes a shell, a rotor with drive package, mounted on the hollow shaft, and a set of heat exchange tubes arranged around the circumference of the stack of disks at some distance from the shaft, and inlet and outlet nozzles. The extreme edges of the disks of the rotor around the entire circumference in the form of blades, oriented either parallel to the radius of the disk, or at an angle ϕ to him, bent in the inter space with a tilt angle of 0<α<180° and made flat or curved length and width with a constant thickness or shaped in cross section. The distance between the disks b is selected from the condition λ>1, λ=b(ω/ν )0.5where b is the distance between the disks; ν is the kinematic viscosity of the gas; ω - cyclic frequency of rotation of the rotor. The rotor cowling is installed with a gap d defined by the condition 0<d/R<0.5, where d is the gap between the shell and the rotor disks; R is the radius of the disk.
These distinctive features increase the gas flow rate and heat transfer rate and enhance the device performance, especially at low pressure.
These characteristics have been identified in other technical solutions in the study of the level of the art, and therefore, the solution is new and involves an inventive step.

Device for dewatering, gas cleaning and heat transfer contains accommodated in the housing (shell) 1 rotor 2 mounted on the hollow shaft 3 drives 4, input 5 and output 6 pipe and tube cooling disks 7, located around the circumference of the disks 4 and passes through the entire stack of disks at some distance from the hollow shaft 3, coaxial him. The extreme edge of the disk 4 is made with blades 8, which may be located in the plane of the disk parallel to the radius or angleϕ with an inclination in the direction of rotation or counter-rotation and can be made flat or curved length and width and can be shaped in section. Blades bent in the inter space at an angle of 0<α<180° in the direction of rotation of the discs, while the blades can overlap or not to overlap the distance between the disks. The rotor cowling is installed with a gap d defined by the condition 0<d/R<0.5, and the distance between the disks is chosen from the condition λ>1, λ=b(ω/ν)0.5where d is the gap between the shell and the rotor disks; R is the radius of the disk; b is the distance between the disks; ν is the kinematic viscosity of the gas; ω - cyclic frequency of rotation of the rotor.
These terms of installation of the rotor provides the increase of gas flow rate and heat transfer rate, especially at low pressure.
The device operates as follows.
The disk rotor 2 during the rotation of the drum 1 transports the gas from the inlet pipe 5 to the outlet 6 with the heat transfer disks with 4 gas through the cooling tubes 7. Tube 7 are connected with the channels of the inlet and outlet of the heat exchange fluid (not shown) and are involved in the process of heat exchange of the rotor 3 in conjunction with the blades 8, increasing the heat transfer coefficient. The location of the disk blades of the rotor at an angle ϕ (see figure 3) and the contour from flat the STI drives at an angle α (see figure 2) to the direction of rotation of the rotor provides a more effective interaction with the flow, which, in turn, provides increased gas flow and the heat transfer coefficient from the disks to gas, especially at low pressure. The location of the blades at an angle ϕ forward rotation of the rotor increases the gas flow, and an angled position ϕ in the direction of rotation of the rotor increases the pressure of the stream.
