Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] see figure 1 The water-sprayed screw steam compressor of the present invention comprises a screw compressor host, and the screw compressor host includes a drive source 1 (such as a motor), a transmission device 2 (such as a shaft coupling or a pulley), a screw rotor, and a compressor body 10. Screw rotor extension shaft 3, synchronous gear 13 and bearing 4, wherein the working section 11 of the screw rotor is located in the working chamber of the compressor body 10, and the screw rotor extension shaft located at one end of the working section 11 of the screw rotor 3 is connected to the drive source 1 through the transmission device 2, and the other end of the working section 11 of the screw rotor is connected to the synchronous gear 13. The compressor body 10 also has a bearing cavity, the bearing cavity is located on both sides of the working...

Abstract

The invention provides a water-spray screw steam compressor. Three seals are arranged between a working cavity of the compressor and a bearing cavity; steam seal is realized through spraying high-pressure liquid water in space between the first seal and the second seal; besides seal through spraying water, the steam absorbing superheat degree can be lowered through spraying water in a steam absorbing cavity to increase the mass flow rate of compressed steam; or water is sprayed in a compression cavity at the steam absorbing end moment to effectively lower the temperature of compressed steam and the steam discharging superheat degree, so that the working process of the compressor is similar to a constant temperature compression process, and the efficiency of the compressor is improved. A pressure stabilization tank is arranged on the steam discharging side of the compressor; the steam pressure in the pressure stabilization tank is adjusted to ensure efficient operation of the compressor under different working conditions. High-temperature water flowing out of a water route of the pressure stabilization tank is mixed with low-temperature softened water or distilled water, the mixed water enters a heat exchanger and is recycled to provide the steam heat of a user and to realize steam superheat degree adjustment; adjustment of temperature and flow of sprayed water can be realized through adjusting flow of the softened water, distilled water or water entering the heat exchanger.

Description

technical field [0001] The invention belongs to the technical field of mechanical steam recompression heat pumps, and relates to a water-spraying screw steam compressor. Background technique [0002] With the increasingly prominent energy problems, high-energy-consuming processes are facing technical requirements for energy-saving transformation. Mechanical vapor recompression technology uses a steam compressor to compress low-temperature steam, which can replace boiler steam after its temperature and pressure are increased. It can be used in different fields such as seawater desalination, sewage treatment, and lye recovery. [0003] Vapor compressor is the key to mechanical vapor recompression technology, and it is also the main technical difficulty and development limitation. Mechanical compressors are mostly rotating machines, which need to be equipped with oil-lubricated bearings. In order to ensure the quality of compressed steam, there must be a reliable seal between ...
