Device for ultrasonic atomization and concentration of ethanol and method for concentrating ethanol

Abstract

The invention discloses a device for ultrasonic atomization and concentration of ethanol and a method for concentrating ethanol. The device comprises an ultrasonic atomization tank with an ultrasonic atomizer, a concentrator and a collector, wherein the concentrator consists of a cylinder and a piston reciprocating in the cylinder; a treatment tank is formed between the cylinder and the piston; a material inlet and a material outlet are formed before a piston front dead point of the treatment tank; the material inlet of the treatment tank is provided with a material inflow one-way valve; the material outlet of the treatment tank is provided with a material outflow one-way valve; the material inlet of the treatment tank is communicated with an atomized matter export of the ultrasonic atomization tank; and the material outlet of the treatment tank is communicated with the inlet of the collector. In the method for concentrating the ethanol, the device is adopted. Compared with the prior art, the invention has the advantages of high recovery efficiency of the ultrasonically atomized matter, simple device and the like.

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 generated by ultrasonic waves. 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 dire...

Problems solved by technology

In the ultrasonic concentration device using blast equipment, the power efficiency of the blast equipment is low, and the energy consumption is relatively high; at the same time, an appropriate amount of gas needs to be added; there are also potential requirements for the pressure and rate of the carrier gas, such as for the common coil type Condensation and trapping device, the coiled condensing tube creates considerable resistance to the flow of gas. To make the gas with mist pass through smoothly, the blower device must provide the gas with a pressure higher than a certain value, but the air pressure is too large. Excessive speed will greatly shorten the residence time of the mist in the capture device, which is not conducive to its smooth capture and condensation, and the uncaptured mist will continue to circulate in the entire loop with the airflow until a certain It is agglutinated in the secondary cycle, and a lot of transmission energy is consumed in this process, so it is necessary to further improve the economy of the ultrasonic concentration device powered by blast
