Abstract

This invention relates to an adsorbent gas drying technique and can be used in the chemical industry in air conditioning. The purpose of the invention is to reduce energy consumption. The drum dryer includes an electric heater installed in the inlet of the dryer, a regular nozzle consisting of flat and profiled ribbons covered with a layer of sorbent coiled on a sleeve. The nozzle forms many channels parallel to the shaft. In the outlet part of the dehumidifier there is a sector steam trap chamber located coaxially with the electric heater and forming with it a single duct for the regenerating gas. The vapor chamber is connected to an annular chamber, which serves to collect and output the vapor-gas mixture from the dryer. 2 Il.

Description

This invention relates to an adsorbent gas drying technique and can be used in the chemical industry in air conditioning.

The purpose of the invention is to reduce energy consumption.

FIG. 1 shows the proposed dryer, longitudinal section; in fig. 2 - steam discharger, section.

The dryer contains case 1. In case 1 of the drum dryer there is an electric heating element 2 in the form of a sector fixed on the shaft 3. On the case of the dryer 1 on the inner side there are current-conducting tires 4 in the form of rings, through which current collectors slide current when electric heater rushes. The hygroscopic nozzle 5 consists of flat and profiled ribbons, covered with a layer of sorbent and curled around the sleeve 6, inside which is shaft 3. Nozzle 5 has many channels parallel to the shaft. In the outlet part of the housing 1 there is a sector steam trap chamber 7. The rotary chamber 8 serves to collect the vapor-gas mixture coming from the vapor trap chamber 7. The annular chamber 8 has a nozzle 9 that serves to remove the vapor-gas mixture from the gas dryer. The shaft 3 is driven by an actuator 10, consisting of an electric motor and a gearbox.

The steam discharge chamber 7 comprises a hub 11, a separating ring 12, lateral radially arranged walls 13 forming a sector closed by the wall 14, and an opening 15 in the separating ring 12 for outputting the vapor-gas mixture to the annular chamber 8 of the gas dryer. For durability, the steam chamber 7 has stiffening ribs (rods) 16 connecting hub 11 with a separating ring 12. Ring 12 separates the annular chamber 8, where the vapor-gas mixture flows, from the dried gas.

The electric heating element 2 and the steam discharge chamber 7 are rigidly fixed on the shaft 3, are arranged coaxially with the vertical axis of the nozzle 5 of the dryer and form

a single duct for the passage of the regenerating gas.

The dryer works as follows.

The common gas for osusk and sorbent regeneration enters the housing 1, where the shaft 3 rotates with a low speed drive (1–10 rpm) with a fixed electric heating element 2 and a steam removal chamber 7. A large part of the gas flow passes through the hygroscopic nozzle 5, drained and supplied to the consumer, and a smaller one) passes the heating element 2, then the nozzle with a moist sorbent, where it evaporates moisture, and then the vapor – gas mixture enters the steam discharge chamber 7, passes the opening 15 in the separating separating ring 12 and enters into the annular chamber 8, from where it is removed through the pipe 9 to the atmosphere.

Claims (1)

Invention Formula five A dehumidifier for gases, including a drum, filled with a nozzle with a sorbent, an electric heater for the regeneration of a sorbent, means for outputting the vapor-gas mixture and a drive shaft, characterized in that 1 that, in order to reduce energy consumption, the nozzle is made of regular profiled material to form channels parallel to the shaft, and the means for outputting the vapor-gas mixture is made in the form of a secretion chamber located in the output part of the drum, while the electric heater is installed coaxially with the vapor-gas chamber on the drive shaft . fi П / 3 Н 15
