Description
Technical field
The utility model is related to a kind of chemical machinery field, and in particular to one kind evaporation air extractor.
Background technology
, it is necessary to carry out pumping body to evaporator when being evaporated to evaporator, the boiling point of liquid is reduced, is easy to evaporation dense
Contracting.Existing evaporation heat uses reciprocating vacuum pump, and abrasion is big, and steam easily corrodes parts, and vacuum is relatively low, and not
Surely, consume energy high, maintenance cost is big, and evaporation efficiency is low.
The content of the invention
Stable in order to provide a kind of wear-resistant, pumping, reduction uses the vavuum pump of power consumption and maintenance cost, the utility model
The technical scheme of use is as follows.
A kind of evaporation in vacuo injection apparatus, including installed in the water stream injection pump, evaporator, high-pressure hydraulic pump of High Altitude Platform, water
Jet pump selects graphite jet pump, and the exhaust tube of evaporator steam (vapor) outlet and water stream injection pump is connected, and water stream injection pump top is by taking out
Water pipe is connected with high-pressure hydraulic pump, and cooling tower is provided with the pipeline that high-pressure hydraulic pump is connected；
Smaller than nozzle ends tube chamber in the middle part of trunnion nozzle in water stream injection pump, the lower end connection of water stream injection pump declines conduit,
Decline to be provided with a pond, pond below conduit and high-pressure hydraulic pump is installed, the length for declining conduit is 10-20m.
According to described evaporation in vacuo injection apparatus, the length of described decline conduit is 20m, and external diameter is 30cm.
According to described evaporation in vacuo injection apparatus, cooling tower is installed on the pipeline that described drinking-water pipe is connected.
According to described evaporation in vacuo injection apparatus, the outside of described evaporator is connected with tubular heat exchanger, evaporation
The bottom of tank also carries baiting valve.
The original High Altitude Platform of the utility model design improvement, using Venturi effect, atmospheric pressure difference of height, with water in stone
Circulated in black jet pump, produce negative pressure of vacuum, instead of reciprocating vacuum pump.The more conventional reciprocating vacuum pump of the present apparatus, very
Reciprocal of duty cycle is more stable, and evaporation efficiency is significantly improved, by the use of nearly 2 years, operational excellence.

Embodiment
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
The utility model is a kind of evaporation in vacuo injection apparatus, including installed in water stream injection pump 2, the evaporator of High Altitude Platform
8th, high-pressure hydraulic pump 7.Water stream injection pump 2 selects graphite jet pump, and graphite jet pump has the advantages that resistance to acid gas corrosion, therefore
Solve conventional aspiration pump easily impaired defect.The steam (vapor) outlet of evaporator 8 is connected with the exhaust tube 1 of water stream injection pump 2, water
The top of jet pump 2 is connected by drinking-water pipe 1 with high-pressure hydraulic pump 7.The middle part of trunnion nozzle 3 in water stream injection pump 2 is than nozzle ends pipe
Chamber is small, and the high speed injection water of trunnion nozzle 3, caliber increases suddenly so that negative pressure, referred to as Venturi effect are produced near nozzle,
Claim venturi effect, the negative pressure produced using this effect can be evacuated to evaporator 8, the boiling point of reduction evaporation liquid.
The high-temperature steam that the water of injection comes with negative pressure extracting is mixed, and the lower end connection decline then along water stream injection pump 2 is led
Pipe 5 declines.Decline the lower section of conduit 5 and be provided with installation high-pressure hydraulic pump 7 on a pond 6, pond 6, high-pressure hydraulic pump 7 is endlessly
Recirculated water is sprayed through water stream injection pump 2, pond is then recovered to.The length for declining conduit 5 is 10-20m.Described decline conduit
5 length is preferably 20m, and external diameter is 30cm.
Because the high-temperature steam that evaporator 8 is drawn into constantly is extracted, then mixed with recirculated water so that circulating water temperature is not
Disconnected rise, this is accomplished by cooling down recirculated water.Cooling tower 11 can also be installed on the pipeline that high-pressure hydraulic pump 7 is connected.This reality
Apply in example, cooling tower 11 is also equipped with the pipeline that drinking-water pipe 1 is connected recirculated water is cooled down, prevent circulating water temperature continuous
Rise.
The outside of evaporator 8 is connected with tubular heat exchanger, and the liquid of inside evaporation is heated by circulating hot water.
The bottom of evaporator also carries baiting valve 10, for carrying out blowing operation after being evaporated.
