Screw type water vapor compressor unit and working method

Abstract

The invention relates to a screw type water vapor compressor unit. The screw type water vapor compressor unit comprises a main motor, a screw type compressor, a gas-liquid separator, an oil tank, an oil cooler and a softened water tank; the output end of the main motor is connected with the screw type compressor through a coupling; the gas inlet end of the screw type compressor is connected with avapor inlet pipe; the gas outlet end of the screw type compressor is connected with one end of a vapor outlet pipe; the other end of the vapor outlet pipe communicates with the gas-liquid separator;the lower end of the gas-liquid separator communicates with a main drain and an auxiliary water spraying pipeline. Compared with the original pump body pressurization manner, the screw type compressorhas the higher pressurization capability; the oil way circulation manner is adopted, so that lubricating oil in the compressor is cooled effectively, and meanwhile, the problem of reduction of lubrication efficiency due to the excessively high temperature of the lubricating oil is avoided; metal scraps carried by the lubricating oil after use are reduced by the aid of a coarse oil filter, damageto an oil pump is reduced, meanwhile, filtration is performed again by the aid of a fine oil filter, and damage to the screw type compressor is reduced.

Description

technical field [0001] The invention relates to the technical field of steam boosting, in particular to a screw-type steam compressor unit and a working method. Background technique [0002] High-pressure steam plays an important role in many industrial productions, and the existing steam boosting technology mostly uses pump boosting and works in a high-temperature and high-pressure environment at the same time, resulting in overheating of the pump body, which in turn increases the loss of the mechanical structure and shortens the The service life of the pump body is shortened. At the same time, the cooling method of the existing pump body is mostly water cooling, and the lubricating oil in the pump body reduces the lubrication efficiency when the temperature rises. The lack of an external structure makes the natural cooling of the oil circuit to the oil tank unable to meet the demand. At the same time, the metal debris generated by the compressor's working wear will flow ba...
