Although technique scheme can realize the adjustment of vapor pump, need manually to regulate, or passed to control mechanism regulate by steam test instrumentation acquisition flow, temperature signal.But vapour survey instrument is difficult to Measurement accuracy steam parameter, control mechanism price is higher, and is difficult to adapt to working steam parameter fast-changing operating mode, such as: adopt solar energy to provide the device of working steam for multiple-effect distillation device.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of Dynamic Self-Adjusting vapor pump is provided.
Technological scheme of the present invention is summarized as follows:
A kind of Dynamic Self-Adjusting vapor pump, comprise jet pump diffusion room 1, the diffuser 14 of jet pump diffusion room 1 is provided with mixed vapour outlet 4, the mixing section 13 of jet pump diffusion room 1 is connected with suction chamber 11, the upper locular wall of suction chamber 11, lower locular wall, front locular wall or rear locular wall are provided with jetting steam caused inlet duct 3, the left locular wall of suction chamber 11 runs through and is provided with working steam and enters pipe 2, working steam enters one end that pipe 2 is positioned at suction chamber 11 inside and is connected with nozzle 5, porous fixed plate 8 is fixedly installed at the nozzle trunnion 10 of nozzle 5, porous fixed plate comprises center hole and outer perimeter holes, piston rod 12 is fixedly connected with regulating piston 6 through one end after spring 7, the other end is flexibly connected with pin 9 through after the center hole of porous fixed plate 8.
The axial cross section of the side, steam inlet of regulating piston 6 be enter with working steam isosceles triangle that the center line of pipe 2 is symmetry axis or symmetrical parabolic arc.
Outer perimeter holes on porous fixed plate 8 is preferably annular and is uniformly distributed.
A kind of Dynamic Self-Adjusting vapor pump of the present invention can adapt to that vapor pump is frequent at working steam pressure, be automatically found optimal working point under the operating mode of rapid fluctuations; Under the condition of equal working steam, produce higher jet coefficient, thus improve working efficiency; Structure is simple, easily manufactured.The present invention is particularly suitable for solar energy heat utilization device and provides the occasion of working steam for low temperature multiple-effect distillation sea water desalting device, for solar energy optical-thermal distillation seawater desalinating device provides a kind of effective steam injection equipment, has good Social and economic benef@.
