Continuous service is constantly mixed into condensed water in recirculated water, and the temperature of recirculated water is higher and higher, causes recirculated water to the condensation energy of steam
Power weakens, and then influences the vacuum degree of system.Therefore, large-scale plant is frequently with cooling tower to circulating water.But for small-sized
Process units, a common simple condensate water pot recycling condensed water simultaneously recycle, and cannot achieve the cooling of recirculated water, with
The extension of device runing time, circulating water temperature gradually rise, and vacuum degree gradually decreases, or even fail to meet production requirements.
Therefore, it is necessary to provide a kind of device that may be implemented to cool down to the recirculated water of circulation water pot.
Summary of the invention
The purpose of this utility model is that in view of the deficiencies of the prior art and defect, providing one kind can solve the above problem
Vacuum jet package (devices).
To achieve the above object, the utility model is achieved by the following technical solution:

2, the utility model is by recycling water pot in I and " u "-shaped pipe, Ji Nengbao being arranged on Section II circulation water pot communicating pipe
The recirculated water of card I circulation water pot smoothly flows into Section II circulation water pot, while being avoided that the circulation aqueous when I circulation water pot again
When position is lower than connecting tube outlet, I circulation water pot, which is in, is communicated with the atmosphere state, and the vacuum degree of entire production system is caused to be broken
It is bad.
3, inclined baffle plate is arranged by recycling in Section II in the utility model in water pot, and recirculated water is flowing into Section II circulation
After water pot, the surface area of water increases, and the heat in recirculated water is effectively distributed.
4, exhaust pipe is arranged by recycling the tank deck of water pot in Section II in the utility model, can make the steam in recirculated water tank
It is discharged with exhaust pipe, takes away the partial heat in recirculated water, play the role of further decreasing circulating water temperature, meanwhile, exhaust
Pipe is connected to liquid seal trough, is acted on by the fluid-tight of liquid seal trough, avoids exhaust pipe in state is communicated with the atmosphere, is more advantageous to guarantor
Hold the vacuum degree of whole system.The steam that liquid seal trough can enable recirculated water volatilize simultaneously recycles.
5, the utility model baffle plate and exhaust pipe are used cooperatively, and baffle plate increases the volatilization of recirculated water, exhaust pipe will
The heat of volatilization is taken away in time, is more advantageous in recirculated water the volatilization of heat and takes away.
