Description

The utility model relates to adsorption drying and purification of high pressure gases and may find application in the chemical, gas industry, and other areas where it is necessary to use dried and purified high pressure gases.

Various designs of devices for drying and purifying compressed gas (air) are known.

For example, an adsorber is known that contains an adsorbent-filled housing with an upper inlet and a lower outlet, in which filter elements are located (AS USSR No. 1279657, IPC B01D 53/04, 1986 publication).

There is also a device for drying air containing flowing modules with sorbents for separating the aqueous component, the modules being made in the form of cartridges with a gas-permeable shell and filling with sorbents, the sorbents being adsorbents such as silica gel, activated alumina, zeolites (patent application No. 2000115389, IPC B01D 53/22, publication 2002).

A known cartridge for an air dryer having an inlet connected to a source of compressed air, an outlet connected to the reservoir, and a dehumidifier located between the inlet and outlet and configured to remove moisture from the air passing through the air dryer, and the cartridge is equipped with coalescing means capturing droplets of oil that are present in the air coming from a source of compressed air, while coalescing

the products contain filter elements and are located after the desiccant (international application WO 2005/000448, IPC B01D 53/26, publication 2005).

A device for drying and cleaning compressed air, containing a cylindrical body, a base with inlet and outlet fittings, and a cover. A vertically oriented filter cartridge with a cylindrical shell with a bottom and an adsorbent located inside is placed with an annular gap relative to it (BAUER KOMPRESSOREN filter system - prototype, copy attached).

A disadvantage of the known device adopted as a prototype is the possibility of the appearance of mechanical particles of different fractional composition at the cartridge output resulting from the destruction of adsorbent granules, which is unacceptable for air intended for breathing, and also negatively affects the operation of shutoff valves.

The task of creating the proposed utility model is to expand the arsenal of technical means used in adsorption drying and purification of compressed gas, as well as increasing the efficiency of the device for drying and purifying compressed gas, reducing material costs for its manufacture and operation, ensuring compactness and ease of use.

The essence of the proposed utility model is as follows.

A device for drying and cleaning compressed gas contains a cylindrical body, a base with inlet and outlet fittings, and a cover. A vertically oriented filter cartridge containing a cylindrical shell with a bottom and with an adsorbent located inside is placed with an annular gap relative to it in the housing. The adsorbent inside the cartridge is filled with two layers of zeolite sequentially arranged along the course of the compressed gas, and

placed between them a layer of cupramite. A fine filter element is mounted over the upper zeolite layer, pressed to the adsorbent layers by means of the cartridge cover. The layers of the adsorbent and the fine filter element are separated from each other by porous partitions. The internal cavity of the cartridge is in communication with an annular gap in the housing of the device through a through hole in the cover of the cartridge. The cartridge cover is equipped with a handle.

Figure 1 shows a device for drying and cleaning compressed gas, a longitudinal section; figure 2 - filter cartridge.

A device for drying and cleaning compressed gas comprises a cylindrical body 1, a base 2 with an inlet 3 and an outlet 4 fittings, and a cover 5. A filter cartridge 6 is installed in the housing 1 of the device, located with an annular gap 7 relative to the housing 1. The cartridge 6 contains a plastic cylindrical shell 8 with a bottom 9, in which the inlet fitting 10 is installed, and a cover 11.

The cavity inside the cartridge is filled with an adsorbent, including two layers of zeolite 12, 13 sequentially located along the compressed gas, and a layer of cupramite 14 placed between them. A fine filter 15 is installed over the upper layer of zeolite 13, pressed against the adsorbent layers by means of the cartridge cover 11 The layers of the adsorbent and the fine filter element are separated from each other by porous baffles 16.

The inner cavity 17 of the cartridge 6 is in communication with an annular gap 7 in the device body through a through hole 18 in the cover of the cartridge 11. The cover of the cartridge is provided with a handle 19.

The initial stream of compressed gas (air) enters the inlet fitting 3, and then through the channel in the base 2 through the nozzle 10 in the bottom 9 enters the cavity of the filter cartridge 6.

Compressed gas passes sequentially through the layers of the adsorbent, where it is dried using zeolite, purification from hydrocarbons with

using capramite, and the final cleaning of mechanical impurities in the filter element 15.

Next, the cleaned compressed gas leaves through the hole 18 in the cover 11, enters the annular gap 7 between the housing 1 of the device and the outer wall of the filter cartridge 6, and then into the channel of the base 2 and exits through the nozzle 4.

When the adsorbent resource runs out, the filter cartridge is replaced. To do this, the cover 5 of the device is removed and the spent cartridge is removed by the handle 19 and replaced with a new one.

Thus, when replacing the cartridge, the adsorbent and filter materials are completely recharged, which are necessary for drying and purifying the compressed gas.

The proposed device is compact and convenient to use, highly efficient in operation, provides a reduction in material costs in the manufacture and operation.
