the cone of the switchgear 5, which alternately connects the adsorbers with a compressed gas line, with a desorption line, with the atmosphere, i.e. through the switchgear, the flow of wet and dry gases is switched.

From the pneumatic actuator 7, the gas, at the pressure necessary to overcome the resistance of the sorbent layer, is sent via the desorption line 13 to the adsorber 2 through the check valve 15 (with closed valves 10 and 14).

By desorbing moisture, the gas from the adsorber 2 through the distribution device 5 you- '. throws into the atmosphere.

With a constant rotation of the inner ‘cone of the switchgear 5, the adsorbers automatically switch: adsorber drying of gas occurs in adsorber 2, and moisture desorption in adsorber 1.

Thus, the installation allows to reduce energy consumption during adsorption drying of gas, using the energy of compressed gas to rotate the inner cone of the switchgear. In addition, the desorption of moisture from the sorbent is carried out at normal temperature, without supplying heat by reducing pressure and purging the sorbent with part of the dried gas.

Non-heated desorption allows to exclude heating equipment from the Taza dehydration unit, which means lower capital costs during use. proposed installation.

Claims (1)

Claim Installation for adsorption drying of gases, which includes a compressor, a switchgear, two adsorbers connected by lines of wet gas, desorption and dried gas, on which a non-return valve is installed, which requires that, in order to reduce capital costs installations by using the energy of compressed dried gas for • regeneration of the sorbent, the switchgear is equipped with a gearbox and pneumatic drive with an additional pipe connected to the desorption line, and the line of the dried gas is equipped with a res ve> rum and flow regulator connected. between themselves and connected through a flow regulator with a pneumatic actuator. The invention relates to the purification and drying of air and air, and can be used, in particular, in the processing of gas and gas condensate, as well as for adsorption separation of gas and air. The purpose of the invention is to reduce the capital cost of the installation by using the energy of compressed compressed gas for the 'regeneration of turbine. The drawing shows the installation for 'drying of gases, General view. The gas dehydration unit consists of two stationary adsorbers 1 and 2, connected to the compressor 3 and to each other by a wet gas line 4, on which a switchgear 5 with a gearbox 6 with a pneumatic actuator 7 is installed. Using a switchgear 5. made in the form of coaxially aligned ground, internal and 20 external truncated cones, the adsorbers are switched from the adsorption stage (gas dehydration) to the desorption stage (sorbent regeneration). . On the dry gas line 8, check valves 9 and 10 are located and a receiver 11 is placed, which is connected to the pneumatic actuator 7 through the flow regulator 12 and is connected to the desorption line 31, on which the check valves 14 and 15 are located, and through the gearbox 6 interacts with the internal . switchgear cone 5. . Installation works as follows. Compressed gas from the compressor 3 enters through the distribution device 5 through line 4 of the wet gas to the adsorber 1. filled with sorbent. In the adsorber 1 is the adsorption drying of the gas. The dried gas through the non-return valve 9 · (πρΜ closed valves 10 and 14) is supplied to the receiver 11, from where the bulk of it enters the consumer. Desorption is carried out by reducing the pressure and simultaneously blowing the sorbent with dry gas. Part of the dried gas from the receiver 11 chere.
