Abstract

The invention allows to improve the quality of cleaning. Products with a porous structure of various configurations, placed in the working compartment 6 of the double-walled casing 4, in which the ancestor ff 5 th 2f I / vacuum is rarefied, are exposed to a vapor-gas mixture entering the working compartment 6 from the sealed chamber 1 by means of the inlet 23 through the bypass valve 22. The vapor – gas mixture flows around the contamination particles without disturbing their adherence to the product. When the maximum pressure in the working compartment 6 is reached, a relief valve 14 opens connecting the working compartment 6 to the drain line 13, disrupting the adhesion of the soil particles to the product and they are removed together with the vapor-gas mixture. Due to the airlift located around the casing 4, a higher and faster vaporization is provided and due to contact with the heated gas entering the airlift from the space 8 between the double walls of the casing 4, the formation of the vapor-gas mixture is accelerated. 1 il.

Description

The invention relates to the cleaning of products, namely, to the technique of cleaning products of predominantly porous structures and capillaries in the vapors of the working agent.

The purpose of the invention is to improve the quality of cleaning.

The drawing shows an installation for cleaning products in pairs of a working agent, a general view.

The installation contains a hermetic chamber 1 for a working agent 2, heaters 3 for a working agent installed in the lower part of the chamber 1, a casing 4 with a hermetic lid 5 and a working compartment 6 for mounting a cartridge 7 with the product in it. The casing 4 has double walls to form a co-agent 2, for example, 1/4 of its volume ;, and

turn on the heater 3, open the valve 18 and at the same time turn on the heater 9, a compressed gas enters the charge line; which reaches the annular cavity 3, is heated by the heater 9, and flows through the non-return valve 12 into the distribution cavity 10. Under pressure of this gas from the distribution cavity 10 is displaced through the openings 11, the working agent inside it and the heated gas bubbled into the rings; 17

Hitting the working agent, the gas flow breaks into many bubbles, as a result of which an emulsified medium appears in the annular gap 17, due to the fact that the specific gravity of the emulsion; less than the specific gravity of the surrounding agent and the gas pressure is higher than the pressure in The sealed chamber 1 emulsified layer of the working agent rises in the stake of the ninth gap between the casing 4 and the shell 15 above the level of the working agent and acts on the working agent like a piston. Having reached the upper edge of the shell 15, the emulsified medium is poured over the bent edges and merges downwards in the form of droplets j which reach the level of the working agent and striking it generate additional particles of the working casing 7 with the formation of an annular crest, increasing its surface 17. These parts form er- 35 evaporation. Emulsified under-lift medium. 1Smithm by TL has an extremeCapacity 8 between the walls of the casing 4 but the developed mass surface is thermally connected to the counting line of the compression exchange between me and the working agent and the gas gas through valve 18, and as a result between which the barrel compartment 6 of the housing is connected by heat balance. With the inlet of the pipe 19 and the valve 21 from the system. That the gas is heated above and fast suction 20 and from the internal cavity of the chamber 1 by means of the bypass valve 22 with the intake 23, the pipe 19 is equipped with a monovacuummeter 24, 45 chamber 1 through valve 25. Chamber 1 is equipped with a heat insulating jacket 26, a cooler 27 connecting the top and additional heaters 9. In the bottom 0 of the casing 4 there is a distribution annular cavity 10 with through holes 11 communicating with the annular cavity 8 between the walls of the casing 4 pos COROLLARY return valve 12. The working compartment 6 housing 4 is connected to manifold 13 through the drainage valve 14 discharge the spent agent. The installation has a cylindrical shell 15, a casing 4 which is missing with a gap, and a reflective disk 16, made in the form of a washer and installed in the shell 15 under the bottom

Under the working agent, it helps to accelerate the heating of the working agent to intense vaporization.

Thus, the presence of an airlift in the chamber for working areiHTa provides accelerated formation of a vapor-gas mixture of elevated pressure. When the pressure of the gas-vapor mixture, in

50 the chamber reaches the limit value, the reverse valve 28 opens, and part of the gas-vapor mixture enters the refrigerator 275 where it condenses and the condensate flows back.

55 into the hermetic chamber 1, the pressure of the vapor-gas mixture is lower, tf and, therefore, cannot exceed the set value.

For carrying out the cleaning operation, through the open lid 5, in the working compartment 6 a cassette 7 with the products to be cleaned is installed and the lid is closed. Turn on the valve 21, together working compartment 6 with a vacuum line 20, and include a vacuum pump. The vacuum in the working compartment 6 is set to a predetermined value by the monovacuum meter 24, the valve 21 is closed and the pump is turned off. The bypass valve 22 is opened, together with the cavity of the sealed chamber 1 and the working compartment 6, so that the vapor-gas mixture through the intake 23, which reaches the products in the cassette 7, penetrates into their cavities and pores, gradually flows into the pre-evacuated working compartment 6 bypassing particles of contamination without transporting them into the cavities and pores and without disturbing their adhesion to the product due to the low kinetic energy of the flow due to its low velocity.

When the monovacuum 24 reaches the limit pressure in the working compartment, the overflow valve 22 closes and opens the relief valve 14, connecting the working compartment 6 with the main 13 drainage, in which the pressure is equal to atmospheric. The vapor-gas mixture is compressed and pulled out of the working compartment 6 into the drainage main, thereby disrupting the adhesion of the soil particles in the pores and cavities with the product and they are carried along with the vapor-gas mixture.

To achieve the greatest effect, the cleaning operation is repeated many times. The spent gas-vapor mixture from the drainage line can be sent to a condensation and regeneration unit for reuse.

The invention allows for improved cleaning quality and performance. Placing a pressurized working compartment for the products to be cleaned in the cavity of the pressurized chamber for heating the working agent allows using the thermal energy of the working agent to heat the casing of the working compartment for cleaning products.

through it and the cassettes with the products to be cleaned, which eliminates the condensation of the vapor-gas mixture on them.

The presence of an airlift with a moving emulsified medium in the composition contributes to a higher and faster evaporation, since due to the extremely developed contact with the heated gas, the working agent receives additional heat, and due to the constant mixing with its airlift, all the working agents take part in the formation, while its evaporating surface increases. In addition, the emulsified medium created by the airlift facilitates an intensive mass exchange between the gas and the working agent, which accelerates the formation of the vapor-gas mixture. The combination of these factors increases the efficiency of the device and reduces the energy consumption for obtaining a cleaning agent - a vapor-gas mixture.

Improving the efficiency of the device causes an increase in the performance of the device. The installation can be used both for cleaning tubes of various sizes, including capillaries, and other products with cavities. The cleaning of porous structures of various configurations, as well as products whose internal cavities are made of such structures, as well as capillaries, is especially effective.
