2nd, the superheater of this mechanical compression type compressor inlet steam, the vertical stagger arrangement setting in superheated steam blender If there is dry heat pipe, the contact area of increase backflow superheated steam and steam so that two kinds of steam are sufficiently mixed heat exchange, ensure mixing The uniformity of gas.
3rd, the superheater of this mechanical compression type compressor inlet steam, it is all provided with steam pipe epimere and steam pipe hypomere Steam control valve is equipped with, circulation of the steam on each steam pipeline section can be controlled respectively, ensures steam in overheat superheated steam Uniform mixing in blender.
4th, the superheater of this mechanical compression type compressor inlet steam, is provided with flowback steam control on opposing steam flow pipe Valve processed, after the degree of superheat of superheated steam in superheated steam blender reaches requirement, closing volume steam control valve, without continuing Superheated steam is fed, avoids energy waste.
5th, the superheater of this mechanical compression type compressor inlet steam, temperature biography is provided with superheated steam blender Sensor, temperature sensor are connected to flowback steam control valve, can observe the temperature of superheated steam in superheated steam blender in time Degree, to adjust the aperture of flowback steam control valve, ensure the degree of superheat of superheated steam in superheated steam blender, user Just.
6th, scientific structure design of the present invention is reasonable, is mixed by the circulation of steam in pipeline, is effectively lifted into compressor The degree of superheat of interior steam, ensure the temperature for entering steam in compressor, avoid having liquid entrainment and cause to compressor blade Damage, compressor loss is reduced, extends compressor service life, and trip temperature is entered by temperature sensor and controlled in real time, ensured High efficiency of energy utilizes.
