The multiple-effect forced circulation vacuum evaporation system has the advantages of good heat transfer effect in a heating chamber, compact structure, simple operation and low energy consumption.
Description
Technical field
The invention belongs to the evaporation equipment field.
Background technology
In multi-effect evaporation system, as V(five) the effect vapo(u)rization system, in order to make steam more efficiently from I effect vaporization chamber flow through successively II, III, IV, enter at last V effect vaporization chamber, available technology adopting be to extract on-condensible gas by steam-water spray technique after V effect vaporization chamber, need be through the multistep treatments of one-level steam, the spray of one-level water, secondary steam, the spray of secondary water, three grades of water sprays, this technology consumes steam, energy consumption is large, and equipment is perishable, the impact of leakage vacuum is produced.
Summary of the invention
The object of the invention is to: the heat-transfer effect that proposes a kind of heating clamber is better, and system architecture is compact, and is simple to operate, the multiple-effect forced circulation vacuum vaporation system that energy consumption is low.
The object of the invention realizes by following technical proposals:
A kind of multiple-effect forced circulation vacuum vaporation system, the end effect vaporization chamber that comprises the multi-effect evaporation system afterbody, also comprise barometric condenser, cooling tower, water circulating pump and Roots's Water-ring vacuum unit, described barometric condenser, cooling tower and water circulating pump are linked in sequence and consist of a circulation, the steam (vapor) outlet of the end effect vaporization chamber of described multi-effect evaporation system afterbody is communicated with the steam inlet of described barometric condenser, and the gas vent of described barometric condenser is communicated with described Roots's Water-ring vacuum unit gas access.
In such scheme, produce negative pressure of vacuum by Roots's Water-ring vacuum unit in barometric condenser, impel efficiently steam to flow to the end effect vaporization chamber of afterbody from I effect vaporization chamber, then enter condensation formation condensed water in barometric condenser, gas enters atmosphere by Roots's Water-ring vacuum unit, and condensed water reenters barometric condenser continuation circulation by water circulating pump after cooling tower is cooling simultaneously.
As optimal way, also be provided with the recirculated water cistern between described cooling tower and water circulating pump.
In such scheme, by the daily accumulation of recirculated water cistern, put aside sufficient cooling water, avoid cooling tower cooling water in some situation can't satisfy the needs of the abundant condensation of barometric condenser; And the recirculated water cistern also can play further cooling effect; The water of savings also can use for other equipment simultaneously, achieves many things at one stroke.
Each device effect:
Roots's Water-ring vacuum unit is take lobe pump as main pump, is in series take water ring pump as fore pump.
Roots's pump structure: in pump chamber, having the rotor of two " 8 " fonts to be arranged on mutual vertically on the pair of parallel axle, is 1 a pair of gear band action reverse synchronous rotary motion each other by gearratio.Between rotor, between rotor and pump housing endophragm, maintain certain gap, can realize high rotating speed operation.Due to the continuous rotation of rotor, in pumped gas is drawn into space between rotor and pump case from air entry, then discharge through exhaust outlet.Because air-breathing rear space is full closeding state, so gas does not have compression and expansion in pump chamber.But when rotor top turns over the exhaust outlet edge, when the space communicates with exhaust side, because the exhaust side gas pressure intensity is higher, during some gas recoils the space, gas pressure intensity is increased suddenly.When rotor is rotated further, outside the gas excavationg pump.
Adopt the advantage of Roots-water-ring vacuum system extracting vacuum:
1. compare with original steam-water spray system, Roots-water-ring vacuum system utilizes electric power as driving force, no longer consumes steam, more energy savings;
2. not perishable in equipment running process, longer service life, maintenance cost is low;
3. vacuumizing effect is better, efficient is high, compact conformation, without leaking, the advantage such as capacity is large, and floor space is little;
4. air-breathing even, stable working is reliable, and is simple to operate, easy to maintenance.
Roots-Water-ring vacuum unit have advantages of that efficient is high, compact conformation, without reveal, corrosion-resistant, degree of protection is high;
Roots-Water-ring vacuum unit generally can with the motor direct connection, need not deceleration device.Therefore with little physical dimension, can obtain large capacity, floor space is also little;
7. owing to there is no the metal friction surface in pump chamber, need not be to being lubricated in pump, and also wearing and tearing are very little.Sealing between tumbler and fixture can directly be completed by water seal;
Beneficial effect of the present invention: adopt the combination of Roots-Water-ring vacuum unit and barometric condenser and circulation, take out on-condensible gas, make vacuum environment, greatly improved the heat-transfer effect of heating clamber, and system architecture is compact, simple to operate, energy consumption is low.
Description of drawings
Fig. 1 is the device schematic flow sheet of the embodiment of the present invention.
The specific embodiment
Following non-limiting examples is used for explanation the present invention.
As shown in Figure 1, a kind of multiple-effect forced circulation vacuum vaporation system, the end effect vaporization chamber that comprises the multi-effect evaporation system afterbody, also comprise barometric condenser, cooling tower, recirculated water cistern, water circulating pump and Roots's Water-ring vacuum unit, barometric condenser, cooling tower, recirculated water cistern and water circulating pump are linked in sequence and consist of a circulation, the steam (vapor) outlet of the end effect vaporization chamber of multi-effect evaporation system afterbody is communicated with the steam inlet of barometric condenser, and the gas vent of barometric condenser is communicated with Roots's Water-ring vacuum unit gas access.
Workflow: produce negative pressure of vacuum by Roots's Water-ring vacuum unit in barometric condenser, impel efficiently steam to flow to the end effect vaporization chamber of afterbody from I effect vaporization chamber, then enter condensation formation condensed water in barometric condenser, gas enters atmosphere by Roots's Water-ring vacuum unit, condensed water at recirculated water cistern savings and further cooling, reenters barometric condenser by water circulating pump at last and continues circulation after cooling tower is cooling simultaneously.
The above is only preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., within all should being included in protection scope of the present invention.
