SU601035A1 - Apparatus for controlling the degree of saturation of adsorbent layer - Google Patents

Description

kommenentov pipeline 5, in which before: the control layer placed throttle diaphragm 6. The diaphragm reduces the flow rate of gas in the control layer relative to its speed in the main m adsorbent IB 10-20 times, i.e. 0.01-0 , 03 lg / sec. For korpeiKTiiposiK flow rate "control valve is served by the regulating valve 7.

In addition, the device includes a control unit 8 and a controller 5, which, through a separator: Mechanism 10, opens or stops the preparation into the main adsorber 5 of the original vapor-air mixture through the flue // and through the additional mechanism 12 - to the regenerating environment gas flue 13.

The device works as follows.

The initial vapor-air mixture at the open position of the executive mechanism 10 through the flue duct is fed to the main adsorber 3, the hpc through which the target components from the mixture are adsorbed and remain in the bed, and the non-sorbed ones to the atmosphere 4. In order to control the saturation of the adsorbent bed, mainly adcopj6epe 3, part of the flow from the duct 4 through pipe 5 and through the regulating valve 7 and the throttle diaphragm 6 is directed to the control layer, after which the flow is removed 3 atmosphere. The amount of flux directed through the control layer depends on reducing the flow rate of the s layer to 0.01–0.03 ms by the orifice diaphragm 6, and adjusting this value of the various steam flow mixtures and target components contained in them is carried out by adjusting valve 7 .

The sipnals from the resistive sensors 1 are fed to the control unit 8, which captures the moment of saturation of the adsorbent in the main adsorber 3. At the time of saturation of the adsorbent in the main adsorber, the control unit emits a signal to the regulator 9, which through the dipping mechanism 10 stops the flow of the initial vapor-air mixture to the main adsorber 5, and through the actuator 12, a regenerating medium, for example an inert gas, flows into the adsorber from the duct 13.

During saturation of the adsorbent layer, the main adsorber 3 continuously measures the electrical resistance of the control layer of the adsorbent, and compares these values with the maximum electrical continuity of this layer in the adsorption stage, stored in the control unit am, to determine the moment of reaching a certain value of the difference between these values . Kolda, the difference in the electrical resistance values of the control layer reaches a predetermined value, the control unit issues commands through the controller to the actuators to stop the feed-r to the main unit 5 of the initial sorbent mixture

1Praying regenerating medium.

Regeneration of the main and

the control layer of the adsorbent is carried out, for example, at a constant time of the desorption stage.
