Embodiment Construction

[0017] The detailed structure and operation method of a device of the present invention will be described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the mist collector 7 of the device of the present invention includes: a mist inlet 6 , a motor 8 , a spiral fan blade 9 , a bearing 10 , and a collector cylinder wall 11 . In a stable working state, the spiral blade 9 rotates at a high speed driven by the motor 8 , and the negative pressure generated makes the mist in the ultrasonic atomization tank 2 enter the mist collector 7 through the mist inlet 6 . After the mist enters the trap 7, it continues to move downward. At the same time, under the violent agitation of the fan blades, the mist continuously contacts the fan blades and the cylinder wall repeatedly and fully, and gathers and condenses into a concentrated ethanol solution. Under the action of the centrifugal force, most of the condensate adheres to the wall of the cylinder a...

Abstract

The invention relates to an ultrasonic atomization apparatus for ethanol concentration and an ethanol concentration method. The apparatus of the invention comprises an ultrasonic atomization tank provided with an ultrasonic atomizer, a mist trap and a collector; the mist trap consists of a cylindrical shell and a spiral blade capable of rotating in the cylindrical shell; the spiral blade is in a porous sheet shape; an inlet of the mist trap communicates with a mist outlet of the ultrasonic atomization tank; an outlet of the mist trap communicates with an inlet of the collector. The mist trap has two functions of guiding and trapping mist. The ethanol concentration method of the invention employs the above apparatus. Compared with a prior art, the invention has advantages of high recovery efficiency of mist atomized by ultrasonic and low energy consumption.

Description

technical field [0001] The invention relates to a device and method for ultrasonically atomizing and concentrating ethanol, in particular to a method for recovering mist produced by ultrasonic atomizing. Background technique [0002] Biomass has the advantages of renewable, large output, storable, and carbon cycle. The development of biomass energy is an effective way to solve the fossil energy crisis. Bioethanol is a kind of biomass energy that has received more attention. The use of cellulose waste from agriculture and forestry to produce cellulosic ethanol has a good research prospect. Biomass is converted into glucose through pretreatment and other steps, and then ethanol is obtained through microbial fermentation. Biomass can be broadly classified into sugary raw materials, starchy raw materials, and cellulose raw materials. The technology of producing fuel alcohol from sugary raw materials and starchy raw materials is very mature. Brazil mainly uses sugarcane to d...
