Description

The invention relates to devices for the adsorption purification of gases and can be used in cryogenic systems to obtain high-frequency inert gases.

The aim of the invention is to increase the efficiency of the cleaning process by removing the heat of adsorption and reducing the hydraulic resistance.

FIG. 1 shows the adsorber, general view; in fig. 2 — an installation unit for partitions forming channels — in FIG. 3 - installation unit -shaped boxes.

The adsorber includes a housing 1 made of plates 2 forming channels 3, which are connected by zigzag grooves 4. The channels are filled with adsorbent 5. Partitions 6 are formed between the channels with the adsorbent, forming channels 7 and 8 for coolant and gas entering the cleaning, respectively. At the gas inlet to the adsorbent layer, perforated 9I-shaped boxes are installed. In the lower and upper parts of the canister housing

Chambers of an entrance 10 and an exit 11 of cleared gas are located. In the upper chamber 11 there is a nozzle 12 of the outlet of the gas to be purified, and in the lower chamber 10 there is a purge port 13. In the upper and lower parts of the canister case, there are collectors of the inlet 14 and outlet 15 of the coolant and a collector 16 for the inlet of the gas to be purified. A hatch 17 is located at the top of the adsorber to fill the adsorbent.

The adsorber operates in two modes: adsorption and desorption,

In the adsorption mode, a coolant is supplied to the collector 14, which enters the cavity of the channels 7 located between the channels 3 with the adsorbent and passes through. the nozzle goes up through the collector 15. Through the collector 16, channels 8 are supplied with the gas to be purified, which is thermostatically controlled by heat exchange with the coolant passing through channels 7, enters the inlet chamber 10 and through the A-shaped perforated ducts 9 into channels 3 with the adsorbent. Passing through the adsor layer

bent, the gas is cleaned of impurities, enters the output chamber 11 and is removed from the adsorber through the pipe 12. The heat released during the cleaning and thermostatic control process is used to evaporate the heat transfer medium.

Claims (2)

In the desorption mode, the flow of the gas to be purified is first shut off, then the coolant is removed and the channels 7 are rinsed with coolant. At the same time, the cavity of the channels 3 is vacuumed. After desorption, the adsorber is reintroduced into the adsorption process. Claim 1. Absorber comprising a body, plates, zigzag spacers, channels with adsorbent, gas inlet and outlet manifolds, characterized in that, in order to increase the efficiency of the cleaning process due to removal of adsorption heat and reduction of flow resistance, the adsorber is equipped with baffles that form coolant and gas channels, and at the gas inlet to the channels with adsorbent perforated boxes / 1-shaped. 2. Adsorber pop. 1, that is, that the gas channels are located between the coolant channels, and the coolant channels are between the channels with the adsorbent. -; 7 five Phie. / F d 68 five eight 7 (e. phage. five
