Separate liquid and gas filtration system, re;

The device provides, by comparison with the filtration of a gas-liquid mixture, the reduction of the hygienic resistance of Yun 11 filters. During the washing process, filters 10–13 become clogged with soil particles, as a result of which their resistance increases. However, since the bulk of the contaminants are in the washing fluid and are attached to filters 10 and 11, their hydraulics resistance grows much faster during operation of the device than the resistance of the filter 13 through which the gas passes. Therefore, in order for the gas separator 12 not to overflow with the washing liquid and it does not flow into the suction filter 13, during the heating process it is necessary to constantly keep the resistance of the lines through which the washing liquid and gas flow from the gas separator 12 into the gas separator 8, which is accomplished by increasing the resistance of the throttles 14.

To ensure the reliability of the device in the operation of the gas line, connect n kmcha pipes for the gas outlet from the gas separator 12 with the gas separator

8 is equipped with a flow indicator 15 with a transparent insert made, for example, from plexiglass. This allows the visa to determine if the gas separator 12 is filled with the washing liquid and the washing liquid appears in the gas line, then, increasing the resistance of Ise to stop the washing liquid from the gas separator 12 to the gas line and prevent the gas separator from overflowing with the washing liquid.

The gas leaving the gas separator 8 passes through the filter drier 16, and at the expense of the exhaust gas 9 there is a suction of condensate and washing liquid vapors from the filter drier 16, which improves the quality of the separation of liquid vapors from the gas emitted into the atmosphere. Separated by the filter-moisture separator 16 condensate and liquid peers along the line including the check valve 17 and the choke 18, and then through the ejector

9 enter the gas separator 8, where additional separation occurs again.

liquid vapor from gas. Adjusting the flow rate of the suction vapors of the washing liquid is accomplished with help of droplets 18. At low speeds of the washing liquid, at which sufficient vacuum is not created in the ejector 9, for example at the moment of starting (stopping) the pump, stopping the operation of the device, preventing the ejector 9 in the filter-separator 16 is carried out using a check valve 17.

Due to the fact that the gas emitted into the atmosphere additionally passes through the filter-separator, the outlet for the condensate outlet of which is connected to the ejector, the quality of the separation of liquid vapor from the gas emitted into the atmosphere is increased, which allows the proposed device to be used during operation. with harmful cleaning fluids. The suction of condensate from the Filter-moisture separator, which is automatic during the washing process, also reduces the labor intensity of the stand maintenance and increases its reliability due to the depot removal of condensate from the filter-moisture separator into the atmosphere,
