Description
Technical field
The present invention relates to a kind of apparatus and method of concentrating ethanol through ultrasonic atomization, particularly a kind of method of the spray that reclaims ultrasonic atomizatio generation.
Background technology
The carbonaceous organic material matter take plant as source that living beings general reference is all, plant is accepted the light and heat that the sun provides, and is carbonaceous organic material material by photosynthesis by airborne carbon dioxide conversion, portion of energy is stored simultaneously.Advantages such as living beings are renewable with it, output is huge, can store, carbon cycle and noticeable, and in multiple clean alternative energy, unique liquid fuel that is converted into, has very large compatibility with fossil fuel.Therefore, with high-tech development with utilize living beings prepare liquid fuel, day by day cause the attention of countries in the world.
Living beings can be divided into saccharine material, starchy material and cellulosic material substantially.The technology that saccharine material, starchy material are produced fuel alcohol is very ripe, widely applies in countries such as Brazil, the U.S..But in general,, it is obviously unpractical relying on molasses, foodstuff starch raw material to solve the very large fuel problem of consumption, particularly all the more so for the larger countries and regions of population pressure.The main process that cellulose fermentation is prepared ethanol comprises the steps such as pretreatment, hydrolysis, fermentation, concentrate, has the deficiencies such as production procedure is long, energy consumption is high, waste water is many, affects the economy of commercial Application.U.S.'s " industrial enzymology " is thought: " if ethanol industry will be survived, just must utilize lignocellulosic to produce ".Utilize glucose direct fermentation to prepare the technique that ethanol is a comparative maturity of grain fermentation industry, and prepare in ethanol process at cellulose fermentation, apply mechanically this technique and make cellulose fermentation ethanol fail so far to walk out Technological Economy pass.Ethanol concentrate in cellulose ethanol technique is all the traditional way of distillation adopting at present, and energy consumption used accounts for the over half of whole technique.Therefore the Diluted Alcohol concentrating method of, studying new low energy consumption has very important significance.
Ultrasonic concentrate is the novel ethanol method for concentration that this area occurs.Ethanol has the too high physical property of surface concentration, and ultrasonic concentration has utilized this character of ethanol just.Ultrasonic concentration unit is made up of ultrasonic oscillator, air blast, several parts of condensate recycling device conventionally.Owing to flowing to, the latent heat of energy Ratios ethanolic solution to be concentrated of oscillator is much smaller, the more energy of the comparable distillation and concentration method of ultrasonic concentration method saving, and the method is specially adapted to the concentrate of Diluted Alcohol solution.The droplet that ultrasonic atomizatio produces is very small, adopts general condensation method or method of trapping, is difficult to after its aggegation, to collect.JP2005066554 has proposed the method for several aggegation spray, comprising: strengthen that volume, cooling aggegation, the recovery unit of recovery unit is airtight, spray-absorption, force blowing to stir, baffle plate is set, spray vibrator is set to spray, these methods can be used in conjunction with, and improve the aggegation efficiency to spray.This recovery system equipment complexity.In the ultrasonic concentration unit of ethanol, the effect of blast apparatus is generally available to gas (being generally air) circulation power, especially makes the spray of ultrasonic generation arrive in trap with air-flow.For example, in JP2005066526, JP2005066553, JP2005066554, CN200810011464.7, there is the example of the ultrasonic technique with blast apparatus.Adopt in the ultrasonic concentration unit of blast apparatus, the dynamic efficiency of blast apparatus is lower, and energy consumption is relatively high, need to supplement proper amount of gas simultaneously, nebulizer gas pressure and speed are also had to potential requirement, for example, for common coiled condensing trapping device, the condenser pipe of coiling has caused suitable resistance to gas mobile, the gas of carrying spray secretly is passed through smoothly, blast apparatus must offer the pressure of gas higher than particular value, but the excessive air velocity of air pressure is crossed conference the time of staying of spray in catching apparatus is shortened greatly, be unfavorable for that it is trapped smoothly, cohesion, the spray of collection at large again along with air-flow in whole loop constantly circulation until in certain circulation by aggegation, many transmission energy in this process, are consumed again, therefore need further to improve the economy of the ultrasonic concentration unit take air blast as power.Adopt the recovery system equipment complexity of these methods, and major part used blast apparatus transmitting power, what have has also used refrigeration plant, and economy is deposited some problems.First, the blast apparatus in closed cycle system is very high to nebulizer gas pressure and rate requirement, and the actual dynamic efficiency of air blast is on the low side; Secondly, flabellum and conveyance conduit to engage precision requirement higher, nebulizer gas pressure and speed are also had to strict requirement; Use refrigeration plant energy consumption higher.
Summary of the invention
