Abstract

The invention relates to the field of vortex energy separation and allows to increase the thermodynamic efficiency of the vortex tube. The dusty gas stream is sent to the nozzle snail inlet 2, from where it enters the energy separation chamber 1, from where the cold transport flows go through the diaphragm 3, and the peripheral hot flows through the throttle valve 5. At the same time, dust from gas flow, which is removed to the dust-receiving bunker 6, and then to the dust collector 7. Part of the hot flow enters the spiral channels 8, where the twisting takes place more intensively due to the spiral-shaped Hoi-shaped channels 8 and as a result audio stream in the direction opposite to the twist j; Snail inlet 2, in this case, the pulp is intensively discharged into the dust-receiving bunker 6. 2 Il.

Description

The invention relates to devices for cleaning and drying gases with the simultaneous utilization of part of the potential energy of gases and can be used in the chemical and metallurgical industries, as well as in refrigeration technology.

The purpose of the invention is to understand the thermodynamic efficiency.

FIG. 1 shows a schematic view of the roar of a pipe; in fig. 2 shows section A-A in FIG. one .

The vortex tube contains a chamber 1 of energy separation with a nozzle snail inlet 2, a diaphragm Z.dl of cold flow at one end and a seperate pipe k on the other connected to the throttle valve 5. There is an annular dust receptacle around the separation nozzle 4 room 7. On the inner surface of the energy separation chamber 1 at a distance of not less than 1.5 times its diameter from the nozzle entrance port 2, spiral channels 8 are made, tapering in the direction of the dust-receiving bunker 6 and connected with him. At the same time, the direction of twisting of the spiral channels is opposite to the direction of twisting of the snail input 2.

Whirling tube; works as follows.

The gas stream containing dust enters the nozzle snail inlet 2, swirls intensively and enters the energy separation chamber 1, where gas is separated into hot and cold streams due to the Ranka effect. Cold near-axial gas flows are output through diaphragm 3, and peripheral hot gas flows out through throttle valves 5..

At the same time in the chamber 1 of the energy separation due to the center

In the United States of America (detachment of the fluff particles from the rotating gas flow occurs. Dust particles are thrown off to the walls of the chamber 1 of 1 and removed to the dust-receiving bunker 6, and then to the dust collector 7.

Part of the hot stream with dust particles falls into the spiral channels 8, where rotational motion is established, which is constantly maintained by the main stream, and the twisting takes place more intensively due to the spiral shape of the channels 8 and due to the swirling flow of gas in the channels in the direction opposite to the twist of the snail one. Inlet 2. In the spiral channel, dust particles are also separated from the gas, only more efficiently, and the location of the channel allows the dust to be removed more quickly to the dust receptacle bunker 6.

Claims (1)

25 claims five A vortex tube for separating compressed dusty gas into hot and cold streams, comprising an energy separation chamber with a diaphragm for a cold flow view at one end and a central separation pipe at the other end and an annular dust receptacle bunker located around the separation pipe differing from that, in order to increase thermodynamic efficiency, spiral channels are made on the inner surface of the energy separation chamber, tapering in the direction of front dust-collecting bunker and connected to the latter, while the direction of twisting of the spiral channels is opposite to the direction of twisting of the snail inlet. 0 five 0 fw.2.2
