Background technology
Traditional vaporising device is connected to form by pipelines such as evaporimeter, vapour liquid separator, condensers, material is concentrated by the heat exchange with steam in evaporimeter, save steam as far as possible in order to improve evaporation efficiency, multiple-effect evaporation is adopted in present evaporation mostly, promptly one imitate the thermal source of the secondary vapour of generation as 2nd effect evaporator, two imitate the thermal source of the secondary vapour of generation as triple effect evaporator.Though multiple-effect evaporation can be saved steam thermal energy greatly, in the actual production, for limited by heat transfer temperature difference, the elevation of boiling point and material evaporating temperature and equipment investment and power consumption, multiple-effect can not infinitely increase, and common multiple-effect evaporation is that triple effect to five is imitated evaporation.This evaporation equipment parts are many, the cost of investment height, and the equipment operating cost is also high.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, a kind of compact conformation, vapor recycle utilization, energy-conservation, investment is low, operating cost the is few evaporation equipment with the turbine compression fan evaporation are provided, main innovation is to use turbine compression fan in vaporising device, by turbine compression fan secondary vapour is carried out engine driven supercharging, improve the saturation temperature of secondary vapour, produce temperature difference, the vapor recycle that is implemented in the evaporimeter reaches energy-conservation purpose.Specifically implement like this: a kind of evaporation equipment with the turbine compression fan evaporation, comprise evaporimeter, vapour liquid separator, condenser, the evaporimeter bottom is provided with the secondary vapor outlet, condensation-water drain, secondary vapor outlet pipeline is connected on the vapour liquid separator, the gas outlet pipeline at evaporimeter top connects condenser, it is characterized in that base of evaporator and top are equipped with the material circulation pipe, be arranged with circulating pump on the material circulation pipe, charging aperture and discharging opening, the escape pipe at vapour liquid separator top connect the steam inlet of inserting evaporimeter top behind the turbine compression fan again with pipeline.The utility model evaporimeter is selected falling film evaporator for use, and solution circulates in the heating tube of evaporimeter by the material circulating pump in a falling film evaporator.Initial steam is given heat with live steam outside pipe, the solution ebuillition of heated is produced secondary vapour, and the secondary vapour of generation is sucked by the turbocharging blower fan behind vapour liquid separator, after the supercharging, the secondary stripping temperature can improve 5-15 ℃, as heating the heating clamber circulating and evaporating that thermal source enters evaporimeter.Behind normal the startup, turbo-compressor sucks indirect steam, becomes heating steam after supercharging, carries out circulating and evaporating continually like this, and the moisture that evaporates finally becomes condensed water and discharges.
In order to reach good supercharging heating effect, turbine compression fan of the present utility model adopts the evolute turbine compression fan, impeller angle of bend with turbine compression fan is increased to 12-16 ° simultaneously, to improve mechanical efficiency, loss reduces friction, wide/the diameter of impeller is set to≤and 0.1, the raising of compression ratio helps the raising of blast, thereby has increased the temperature difference of secondary vapour.In order to stop contacting of steam and extraneous gas, be equipped with mechanical seal on the axle of the utility model turbine compression fan motor side.
Vapour liquid separator of the present utility model bottom is equipped with discharging opening, and pipeline connects the material circulation pipe of evaporimeter.
Condenser of the present utility model is equipped with condensation-water drain, not condensing outlet, and the condensing outlet conduit is not connected on the carbonated drink knockout drum, and carbonated drink is separated
The venthole at top connects a vavuum pump.Like this, the not condensing of evaporimeter top discharge is just taken away by vavuum pump after condenser condenses.
The pipeline place, steam inlet of the utility model evaporimeter is connected with steam and replenishes pipeline, and this steam replenishes heating steam in the pipeline and only is used for replenishing and arranges the not thermal loss of condensing and a part of steam becomes condensed water after the turbine compression fan compression thermal loss.
The utility model adds and takes out the secondary vapour that evaporates by set up a turbine compression fan in evaporation equipment, after the supercharging as the thermal source of evaporimeter, has significant saving steam effect, the evaporation operating cost only is half of traditional quadruple effect band thermo-compression evaporation, the entire equipment cost of investment is low, is particularly suitable for the pre-concentration of big processing, low concentration evaporation.
