Steam jet pump (pressure matcher)
Steam jet pump (pressure matcher)
Structural Feature
A vacuum acquisition device that uses fluid to transfer energy and mass, and uses a certain pressure of water flow to spray out through nozzles symmetrically and evenly distributed with a certain side slope, and aggregate in a focal point
Due to the extremely high flow rate of the jet water, the pressure energy is converted into velocity energy, and the pressure in the suction zone is reduced to produce vacuum
Several high-speed water streams will grab the sucked gas, pass through the contraction section of the venturi tube and fully mix and compress with the throat diameter, perform molecular diffusion energy exchange, and the speed is balanced
When the speed decreases through the expansion section, the pressure increases, and the pressure is greater than atmospheric pressure and sprayed into the storage tank (pool) from the outlet, and non-condensable gas is precipitated. The water is recycled by the centrifugal pump to complete the suction process
Application of steam pressure to match exhaust steam recovery and utilization to suction vacuum
Thermoelectric industry

Typical Case
Nine Dragons Paper (Taicang) Co., Ltd. high temperature and high pressure steam pressure distributor rear desuperheater
The pressure matcher adopts a single nozzle structure, and the shell adopts 12Cr1MoV forgings
Power steam is P1=8.83MPa T1=540°C Q1=8T/H
The absorbed steam is P2=0.8~0.91MPa T2=220~240°C Q2=5T/H
Decreasing temperature water parameter Pb=12~15Mpa Tb=158°C Qb=2T/H
The outlet steam is P3=1.8Mpa T3=240°C Q3=15T/H
The project was put into use in June 2012, with stable operation and good economic benefits
