Description

one

The invention relates to the field of separation and separation of vapor-gas media and can be used in gas, chemical, energy, and other industries associated with the treatment of compressed vapor-gas mixtures.

Vortex chambers (pipes, ejectors) are known for separating the vapor-gas mixture in accordance with the Ranka effect with a nozzle entry in the form of a spiral channel and a coaxial insert inserted along the axis of the housing.

The disadvantage of such constructions is the uncontrollability of the outflows, for example, the lack of adjustment to ensure the constant pressure of the outflows with a change in the pressure of the incoming flow.

The aim of the invention is to ensure the proportionality of the change in pressure (flow) of the effluent depending on the pressure (flow) of the input stream.

The goal is achieved by the fact that the spiral channel is formed by a multi-turn spring placed in the gap between the body and the insert, and is pressed by means of a plunger movably mounted on a coaxial insert, the plunger being provided with an axial channel.

The drawing shows a vortex chamber with oppositely directed discharge channels for cold and hot flows.

The vortex chamber contains a cylindrical body 1 with a nozzle inlet in the form of a spiral channel 2 formed by a multi-turn spring 3 placed in an annular gap between the body 1 and a coaxial insert 4, a plunger 5 with a threaded connection b for preloading it, a channel 7 for outputting hot flow and channel 8 for cold flow, 9 for

tighten the springs 3.

The camera works as follows. The steam-gas note under pressure is fed into the cutting channel 2, formed by the spring 3, and comes out divided into two streams:

hot, moving in close proximity to the inner wall of the housing 1, exiting through the channel 7, and cold, moving in the central part of the housing 1, exiting through the channel 8.

From the spiral channel, the gas under pressure flows under the plunger 5. The required area of the spiral channel through which the gas passes is pre-established using a threaded joint 6.

In the case of an increase in the inlet pressure, the equilibrium established by the preload of the overloads 3 (the end of which is supported by the plunger 5 and the other end rests on the base of the coaxial insert

4) is violated.

The plunger 5 begins to move, compressing the spring 3, thereby reducing the gap between the coils. The flow area of the spiral channel S b-8 decreases, and the gas pressure in the output channels drops.

In case of a decrease in the pressure of the input vapor-gas flow, the reverse process will occur.

To reduce the flow area of the spiral channels or to seal the spring, several parallel springs 9 can be installed.

The vortex chamber can be used for research in separation devices in wide ranges of the vortex effect, without the need to manufacture a large range of vortex chambers.

The proposed camera can be used in anaprata, in which, according to technological or strength requirements, it is necessary to maintain pressure without large

drops, for example, in conjunction with plate heat exchangers, in cases where it is desirable to have the same pressure in the heat exchange spaces;
