Description
Technical field
It the utility model is related to a kind of vaporising device, and in particular to a kind of falling film evaporation device.
Background technology
Falling film evaporation is to add feed liquid from falling film evaporator heating chamber upper tube box, and feed liquid is uniformly assigned in each heat exchanger tube,
And flowed down along heat transfer tube wall in uniformly membranaceous.During under material flow, heated medium heating vaporization, the steam of generation with
Liquid phase enters the separation chamber of evaporator jointly, and for vapour-liquid through being sufficiently separated, steam enters next effect evaporation into condenser condensation is living
Device operates, liquid phase is then discharged by separation chamber as heat medium so as to fulfill multiple-effect.
Existing falling film evaporator, is typically into upper end when feed liquid is fed directly at the feed inlet at the top of evaporator
Cavity, the through hole set through housing surface is separately flowed into heat exchanger tube, but material often occurs in the mode of entrance of this feed liquid
Liquid cannot be unevenly distributed over the situation in each heat exchanger tube, and then make film-formation result in heat exchanger tube poor, when feed liquid is serious even
There is " dry wall " phenomenon, so as to influence evaporation effect.
The content of the invention
The utility model provides a kind of uniform, falling film evaporation device of good effect of heat exchange that forms a film.
To achieve these goals, the technical solution of the utility model is：A kind of falling film evaporation device, including evaporator,
Include feed unit, evaporation element, cooling unit, discharging unit and the separative element being sequentially communicated in the evaporator, it is described
Feed unit includes feed pipe, the affixed horizontal material containing pipe in feed pipe lower end, and the horizontal material containing bottom of the tube sets multiple cloth
Liquid pipe, the liquid distributor bottom are equipped with multiple relief holes；The evaporation element includes heat exchanger tube, and the heat exchanger tube passes through conveying pipeline
Connected with relief hole, the heat exchanger tube runs through evaporation element, cooling unit and discharging unit, and the heat exchanger tube lateral wall, which scribbles, to be added
Hot coating；The cooling unit includes the water inlet and water outlet for being symmetrically disposed on evaporator lateral wall；The discharging unit bag
Expects pipe is included, the discharging unit is connected with separative element by discharge nozzle, and the separative element includes knockout drum, the separation
Pot bottom is equipped with discharge port, and knockout drum is also connected with negative pressure pump.
Compared with prior art, the beneficial effects of the utility model are：（1）Heat exchanger tube lateral wall scribbles heating coating can
Realize accurate control technological temperature, heating and cooling are efficient, and energy consumption is low；（2）The setting of horizontal material containing pipe, liquid distributor and relief hole,
Evaporation feed liquid is uniformly distributed and heat transfer tube wall, improves heat exchange efficiency.

State heat exchanger tube 16 and run through evaporation element, cooling unit and discharging unit, 16 lateral wall of heat exchanger tube scribbles heating coating 17；Institute
State water inlet 18 and water outlet 19 that cooling unit includes being symmetrically disposed on 10 lateral wall of evaporator；The discharging unit includes
Expects pipe 20, the discharging unit are connected with separative element by discharge nozzle 20, and the separative element includes knockout drum 30, described point
Discharge port 31 is equipped with from 30 bottom of tank, knockout drum 30 is also connected with negative pressure pump 32.
Feed liquid to be evaporated enters feed unit from feed pipe 11, enters cloth after flowing into horizontal material containing pipe 12 along feed pipe 11
Liquid pipe 13, then heat exchanger tube 16 is uniformly distributed in through relief hole 14, form liquid film；The heating coating 17 of 16 lateral wall of heat exchanger tube is external
Electrode, using electric energy exchange heat pipe 16 lateral wall heating, heat is transferred to 16 madial wall of heat exchanger tube by lateral wall so that liquid film by
Thermal evaporation forms reduced vapor, heats the temperature of coating 17 and concentration can be selected according to needed for concentration technology.Reduced vapor is downward
Cooling unit is flowed to, cooling water is inputted by water inlet 18, is discharged by water outlet 19, cooling water enters cooling unit and heat exchanger tube
16 contacts, reduce high temperature reduced vapor temperature, and reduced vapor liquefaction continues towards out material list as after concentrate along heat exchanger tube 16
Member, knockout drum 30 is left to through discharge nozzle 20；Negative pressure pump 32 provides negative pressure, reduces the boiling point of concentrate, further concentrates feed liquid, together
When produce a large amount of water vapours, the concentrate after purification is discharged through discharge port 31, and water vapour is then recovered.
