Abstract
A technical object of the present invention is to provide an annular injection apparatus for wet compression which enables sprayed droplets to maximally evaporate without being drained as condensate water, thereby reducing compression work of the compressor. To this end, the annular injection apparatus for wet compression according to the present invention is an annular injection apparatus for wet compression which is used for a compressor including a nose cone and a bell mouth in an inlet of a flow path, in which droplets are sprayed to a portion except for portions directed toward the nose cone and the bell mouth.
Claims3
An annular injection apparatus for wet compression which is used for a compressor including a nose cone and a bell mouth in an inlet of a flow path, wherein droplets are sprayed to a portion except for portions directed toward the nose cone and the bell mouth, comprising:
- multiple annular pipes which are disposed concentrically to one another at intervals in a radial direction;
- and
- multiple nozzles which are disposed on respective annular pipes and disposed at intervals in a circumferential direction,
- wherein the multiple annular pipes are disposed at the portion except for the portions directed toward the nose cone and the bell mouth,
- wherein the multiple annular pipes include:
- a first annular pipe;
- a second annular pipe which is disposed to be spaced apart from the first annular pipe at a first radial interval in the radial direction;
- and
- a third annular pipe which is disposed to be spaced apart from the second annular pipe at a second radial interval in the radial direction,
- wherein the multiple nozzles include:
- multiple first nozzles which are disposed on the first annular pipe at a first circumferential interval in the circumferential direction;
- multiple second nozzles which are disposed on the second annular pipe at a second circumferential interval in the circumferential direction;
- and
- multiple third nozzles which are disposed on the third annular pipe at a third circumferential interval in the circumferential direction,
- wherein the first radial interval is set to be greater than the second radial interval,
- wherein the first circumferential interval is set to be smaller than the second circumferential interval, and the second circumferential interval is set to be smaller than the third circumferential interval, and
- wherein the first and second radial intervals and the first, second, and third circumferential intervals are determined so that air contact areas of the droplets sprayed from respective nozzles are equal to one another.
