Abstract
The utility model relates to an online cleaning device for a centrifugal type composite compressor process system. The online cleaning device for the centrifugal type composite compressor process system comprises a centrifugal type composite compressor and a composite device heat exchanger. A low pressure cylinder outlet water cooler and a high pressure cylinder inlet segregator are installed between a compressor low pressure cylinder outlet of the centrifugal type composite compressor and a compressor high pressure cylinder inlet of the centrifugal type composite compressor in sequence. A high pressure cylinder inlet water cooler separator is arranged between a compressor high pressure cylinder outlet of the centrifugal type composite compressor and a compressor circulating cylinder inlet. An air outlet for the process cycle air of the compressor circulating cylinder is communicated with an air inlet of a water cooler through a cycle air heat exchanger in the composite device heat exchanger. An end of an air outlet of the water cooler is separated into two ways through a high pressure separator, wherein one way is communicated with the compressor circulating cylinder inlet and the other way reaches to a use end through a low pressure separator. The online cleaning device for the centrifugal type composite compressor process system has the advantages of being reasonable in structural design, easy and convenient to operate, effective in guaranteeing the production efficiency of a composite compressor unit, and safe and smooth in long period working.
