Description

FIELD OF THE INVENTION The invention relates to power engineering, in particular to devices for compressing gas.

The aim of the invention is to reduce hydraulic losses.

The drawing shows a wave pressure exchanger circuit.

The wave pressure exchanger contains a rotor with longitudinal gas exchange - iQ 6. The vacuum wave reaches the left

Channels 2 and two end caps 3 and 4 with windows 5-8 for supplying and discharging compressive and compressible gases. Moreover, windows 5 and 7 for supplying compressive and compressible gases are made in one of the end caps 3, and window 6 and 8 for discharge are in the other. The pressure exchanger is also provided with additional windows 9 and 10, located in the zone of the window 8 for the discharge of compressible gas,

The pressure exchanger operates as follows.

At steady-state engine operation, the rotation speed of the rotor 25 I is matched with the speed of propagation of the pressure wave in the longitudinal gas exchange channels 2 so that the pressure wave occurring at the left end of channel 2 at the time it passes from the leading edge of the window 7, through which the compressive gas is fed into the channel 2, reached the opposite end when channel 2 of the leading edge of window 8 passed to remove compressed gas. Reflecting from the open end of channel 2, a pressure wave forms a rarefaction wave moving along channel 2 I check the gas flow and reach its left end when channel 2 passes the rear edge of the window 5, Reflected from its closed end of the wave 35

the end of channel 2 at the moment it passes through the leading edge of window 7, and the compressible gas through window 7 begins to flow into the cell. At the same time, the compression process is not accompanied by stopping and turning of air and gas flows with maximum use of the pressure exchanger volume. From the additional window 10, the gas enters the turbine blades (not shown in the drawing), which causes the rotor 1 of the pressure exchanger to rotate. The air also passes through the additional window 9

Thus, eliminating the rotations of the gas and air flows reduces the hydraulic losses of the pressure exchanger and increases its efficiency.

Formula of invention

A wave pressure exchanger containing a rotor with longitudinal gas exchange channels and two end caps with windows for inlet and outlet of compressive and compressible gases, about and in order to reduce hydraulic losses, inlet windows compressing and compressible gases are made in one of the end caps, and the opening for the outlet - in the other.

The vacuum generates a pressure wave that reaches the opposite end of channel 1 at the moment it passes through the leading edge of window 6. Reflecting from the open end of channel 2, the pressure wave forms a rarefaction wave moving towards the flow of gas leaving the rotor 1 through the window
