Abstract
The apparatus for conveying and compressing a gaseous medium utilizes thermoacoustic oscillations. The oscillations are generated in a tubular cavity by means of a heat source or heat sink with the medium to be conveyed being taken in through a check valve on one side while being exhausted after compression through a second check valve on an opposite side. During operation, the heat is supplied to the medium within the tubular cavity to generate thermoacoustic oscillations. In one embodiment, a plurality of tubes can be disposed in series relative to a common line. Also, the apparatus can be used in combination with a helium liquifying plant.
Claims4
In combination
- a pair of apparati for conveying and compressing a gaseous medium, each apparatus comprising a line for conveying a gaseous medium, a plurality of vessels connected in series to said line, each vessel having a chamber in communication with said line for receiving gaseous medium, heat exchange means disposed about each said vessel for exchanging heat with a gaseous medium in said respective vessel to generate thermoacoustic oscillations therein, and check valves in said line about each said vessel for conveying a compressed gaseous medium through said line in a downstream direction;
- and
- a plurality of tubes connected to and between respective vessels of each apparatus to increase the amplitude of oscillation therein.
An apparatus for conveying an compressing a gaseous medium comprising
- a first line for conveying a gaseous medium therethrough;
- at least two duct-like vessels connected to said line in series, each vessel having a chamber in communication with said line for receiving gaseous medium;
- at least one heat exchanger means disposed about each vessel for exchanging heat with a gaseous medium therein to generate thermoacoustic oscillations therein;
- a first shutoff element in said line upstream of said vessels to permit delivery of a gaseous medium to said line for compression therein;
- a second shutoff element in said line between said vessels to permit a flow of compressed gaseous medium through said line in a downstream direction;
- a third shutoff element in said line downstream of said vessels to permit exhaust of the compressed gaseous medium from said line;
- a second line for conveying a gaseous medium therethrough;
- at least two duct-like vessels connected to said second line in series and having a chamber in communication with said second line;
- heat exchange means about each vessel connected to said second line for exchanging heat with a gaseous medium therein to generate thermoacoustic oscillations;
- a plurality of shutoff elements in said second line in alternating manner with said vessels;
- and
- at least one tube connecting at least one vessel connected to said first line to a vessel connected to said second line.
