Water spraying device mounted on horizontal split type centrifugal compressor

The utility model relates to a water spraying device mounted on a horizontal split type centrifugal compressor, which is used for solving the problems that water is not directly sprayed into a flow channel of the compressor at present and the existing water spraying device cannot be overhauled in time. The sprayer comprises a sprayer assembly, a machine shell, a machine shell connecting pipe and a first gate valve. The machine shell is provided with water spraying holes, and the water spraying holes penetrate through the machine shell and the partition plate to communicate with the internal flow channel. One end of the casing connecting pipe is connected with the inner flow channel through the water spraying hole, and the other end is communicated with the output end of the first gate valve; the output end of the spray head assembly sequentially penetrates through the first gate valve and the machine shell connecting pipe, communicates with the internal flow channel and sprays water to a flow channel medium.
