ADVISOR FOR DRYING COMPRESSED AIR OF VEHICLE

The invention relates to railway transport and relates to adsorbers for drying compressed air of a vehicle.

Known adsorber for drying compressed air, comprising a housing, a cover, an inlet and outlet nozzle, a granular adsorbent nozzle, a device for compressing the adsorbent layer. (S.I. Elovikova. Desiccant filters: informative leaflet No. 406-87 / Leningrad Interdisciplinary Territory Center for Scientific and Technical Information and Propaganda. - L., 1987, - 4 pp.).

The disadvantage of this adsorber is the use of the adsorbent in bulk. This leads to intensive wear of its granules during the passage of dried air between them, increased aerodynamic resistance of the adsorber, which leads to compressor overloads, contamination by consumer products of the pneumatic equipment and premature damage to it.

The closest technical solution, selected as a prototype, is an adsorber for drying compressed air of a vehicle, comprising a housing with an inlet pipe and a pipe for exhausting regenerative air into the atmosphere, a cover with an outlet pipe, a granular adsorbing nozzle in the form of a bulk adsorbent clamped by a squeeze, a device between perforated disks with filtering nets (a.s. USSR No. 1223977, V01D 53/26, 1986. Bull. No. 14).

The disadvantage: this adsorber, like the adsorber described, is the use of the adsorbent in bulk, which leads to abrasion of the adsorbent granules when the emptied and regenerative air moves through it, as well as from vibrations and shocks associated with specific UEL MPK7 in 1D 53/26

VIIAMI works of rolling stock of railway transport. This leads to the ingress of abrasive dust into the pneumatic drives of devices, brake devices, disrupting their normal operation, which reduces the operational reliability of rolling stock and the safety of train traffic.

The objective of the invention is to increase the reliability of the adsorber.

The problem is achieved in that in an adsorber for drying compressed air of a vehicle, comprising: a housing with an inlet pipe and a pipe for exhausting regenerative air into the atmosphere, a cover with an outlet pipe, a granular adsorbing nozzle placed between the grids and perforated disks, a granular adsorbing nozzle made in the form of a monolith located in a cylindrical cartridge and consisting in volume, for example, from 72 - 78% general purpose zeolite NaX grade A TU 38.10281-88 and 22 - 28% polyethylene 108 white, grade 1 GOST16337-77. In this case, the degree of air drying remains within the specified limits.

A new feature has been introduced into the adsorber: instead of the granular adsorbing granular nozzle, the nozzle in it used a nozzle in the form of a monoblock located in a cylindrical cartridge, which reduces the wear of the adsorbent during operation of the adsorber.

The invention is illustrated in the drawing, which shows a schematic diagram of an adsorber for drying compressed air of a vehicle.

The adsorber contains a housing 1 with an inlet pipe 2 and a pipe 3 for exhausting regenerative air into the atmosphere, a cover 4 with an outlet pack: a cabin 5, a granular adsorbing nozzle in the form of a monoblock 6. The monoblock 6 includes a cylindrical cartridge 7, in which the granular is formed: adsorbent nozzle 8, perforated disks 9 and 10, filter mesh 11 and 12. Adsorbent nozzle 8, consisting, for example, of 72 - 78% of general purpose zeolite NaX grade A TU 38.10281-88 and 22 - 28% polyethylene. on white 108 , grades 1 GOST 16337-77,

after molding in the cartridge 7 is subjected to volume oeoipeey at a temperature of 250 - 280 ° C for 6 hours with the rotation of the cartridge around its axis with a speed of rpm

The adsorber for drying the compressed air of the vehicle operates as follows :.

Wet compressed air through the inlet pipe 2 enters the space between the housing 1 and the all-in-one unit 6, loses speed, washes it, losing large particles of moisture, enters from below through the perforated disk 9 and the filter screen 11 into the unit 6, is dried in it and through the filter the mesh 12, the perforated disk 10 and the outlet pipe 4 is supplied to the consumer. The regeneration of the monoblock 6 is carried out by a reverse flow of dry air, which enters the adsorber through the outlet pipe 5, passes through the adsorbing nozzle 8, absorbs moisture accumulated in the air drying cycle, and is discharged into the atmosphere.

The proposed adsorber for drying compressed air of a vehicle is more reliable in operation due to the implementation of the adsorbing nozzle in the form of a monoblock, which reduces its wear during operation of the adsorber.

Thus, the proposed adsorber while maintaining the specified parameters of the mass transfer processes is more durable, provides pneumatic systems with high-quality compressed air, which increases their operational reliability and the safety of railway rolling stock.
