Abstract

FIELD: ventilation; air conditioning.

SUBSTANCE: device can be used in buildings and premises of different purpose for cleaning and drying gas and air and for heat exchange. Device for cleaning and drying gas and air has case, rotor provided with pack of discs fastened onto hollow shaft, which has channel for heat exchange, and inlet and outlet branches. Channel of heat exchange is made in form of a set of heat-exchange pipes, which pass through the whole pack of discs and disposed along their circle at some distance from hollow shaft coaxial to its axis. Heat-exchange pipes communicate with shaft by means of radial located channels to form closed heat-exchange channel. Set of heat-exchange pipes is placed onto discs of rotor. Heat-exchange pipes are fastened to any disc of rotor inside bushings made of heat-conducting material to provide thermal contact, for example, by means of heat-conducting glue.

Description

The invention relates to ventilation and air conditioning and can be used in air treatment devices installed in buildings and structures for various purposes, in particular in residential and public buildings, in livestock buildings for drainage of gas, including air with its simultaneous purification, as well as for purification of other gases and heat transfer.

A device for draining and purifying air is known, comprising a housing with tangentially located inlet and outlet nozzles and a hollow shaft located in the housing with separation discs mounted on it. The housing in the lower part has a longitudinal slit window for condensate drainage / 1 /.

The disadvantage of this device is the low productivity of the installation.

A device is selected for the prototype, in which the heat exchange channel is made in the form of an annular gap formed by the inner wall of the hollow shaft and a hollow cylinder coaxially located with it, in the end walls of which there are channels connecting the annular gap with the shaft cavity / 2 /.

The disadvantage of the prototype is the low values of the coefficient of heat transfer from the heat transfer fluid to the rotor disks due to the small value of the fluid velocity in the annular channel of the rotor.

The objective of the proposed technical solution is to increase the productivity of the device for heat transfer.

The problem is solved due to the fact that the device for drainage, gas purification and heat transfer, contains a housing, a rotor with a package of disks mounted on a hollow shaft with a channel for heat transfer, as well as input and output pipes. The heat exchange channel is made in the form of a set of heat exchange tubes passing through the entire package of disks and located around their circumference at a certain distance from the hollow shaft, coaxial to its axis, and communicating with the hollow shaft through radially arranged channels, forming a closed heat exchange channel.

A method of assembling the rotor of a device for draining, purifying gas and heat transfer consists of placing a set of heat transfer tubes on the rotor disks. Tubes are fixed on each rotor disk in heat-conducting sleeves using heat-conducting material, such as glue.

These signs are not identified in other technical solutions when studying the level of this technical field and, therefore, the solution is new and has an inventive step

Figure 1 shows a General view of the installation, figure 2 is a side view.

The device for drainage, gas purification and heat exchange contains 1 rotor 2 mounted on a hollow shaft 3 disks 4, input 5 and output 6 nozzles, with coaxial channels - supply 7 and removal 8 of the heat transfer fluid, radial channels 9 supply liquid and liquid drain 10 and cooling tubes of the disks 11, spacing sleeves for tubes 12 and for the shaft 13.

The device operates as follows. The disk rotor 2 during rotation in the housing - shell 1 transports gas from the inlet pipe 5 to the output 6, while there is also a heat exchange of the disks 4 with gas. The disks are cooled or heated by heat transfer fluid through tubes 11 located around the circumference of the disks 4 and passing at a certain distance from the hollow shaft 3 coaxially to it, through the entire package of disks. The tubes 11 communicate with the fluid supply channels 7 of the hollow shaft next to the radially arranged fluid supply channels 9, which form, together with the radial channels 10 of the heat transfer fluid outlet and the exhaust channel 8, located in the hollow shaft, form a common closed heat exchange circuit.

The method of assembly of the rotor of the device for drainage, gas purification and heat transfer is as follows. Heat transfer tubes 11 are connected hermetically with radial fluid supply channels 9, which are in turn tightly connected with the supply channel 7 of the hollow shaft 3. Then, discs 4 are strung on the tubes and shaft, having openings by the number of tubes 11 and one coaxial hole in the center for the shaft 3. The disks are strung one after another through heat-conducting bushings 12 on the tubes and 13 on the shaft and fastened to the tubes and the shaft using heat-conducting glue or in another way that does not impair the heat conductivity of the bushes. After placing the package of disks on the rotor, the tubes 11 are hermetically connected to the radial channels for supplying liquid 9, the outlet channels 10, which are tightly connected to the outlet channel 8.
