Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of more energy-conservation, working efficiency is higher, the axial flow vapour compression machine of long service life.
The technological scheme that its technical problem that solves the utility model adopts is: this axial flow vapour compression machine, comprise steam cylinder, front steam seal, rear packing and main shaft, the main shaft two ends are supported fixing by fore bearing and rear bearing and are crossed steam cylinder, front steam seal and rear packing are sealed in respectively the steam cylinder front-end and back-end, it is characterized in that: described steam cylinder top is provided with opening up suction port and air outlet, the steam cylinder below is air chamber, be provided with a plurality of impeller blades that are sleeved on the main shaft in the steam cylinder, all fixedly mount dividing plate and stator between per two adjacent impeller blades, each impeller blade and corresponding dividing plate and stator form a work level.Dividing plate and stator are used for keeping steam flow flow direction and next impeller blade flow inlet angle to be complementary and further diffusion.Many group impeller blades rotate with main shaft, and steam enters steam cylinder from suction port, realizes both vapor compression under the impeller blade effect, and steam is discharged from the air outlet after the compression.
Described impeller blade is installed 3-6 altogether, forms 3-6 work level with dividing plate and stator.Impeller blade quantity can be adjusted according to the actual requirements.
Described fore bearing and rear bearing are installed respectively front bearing box and after the bearing box outward.Front bearing box and after the bearing box play protection and support fixation.
Described rear bearing right side is provided with the coupling that is installed in the spindle end place.
Described impeller blade rotating speed is 3000-12000RPM.
Described suction port working pressure is 0.06-0.085MPa, and air outlet pressure is 0.12-0.15Mpa.
Compared with prior art, the beneficial effect that the utility model has is: design axial flow both vapor compression mode, in steam cylinder, be provided with the many groups impeller blade that is sleeved on the main shaft, all fixedly mount the stator that is used for isolation between per two adjacent impeller blades, during work, this axial flow vapour compression machine compresses the secondary steam that evaporates in the solution, and send vaporizer back to as adding hot vapour source, solution is heated again, realization is to the recycling of heat energy, reach energy-saving effect, have higher efficient with the axial flow vapour compression machine of power, efficient exceeds 5 ~ 10% than roots-type and centrifugal vapour compression machine, and the manufacturing cost is low, be 2/3 of roots-type and centrifugal vapour compression machine, long service life is generally 20 ~ 30 years.
