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 w...

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.

Example Embodiment

[0016] The detailed structure and operation method of a device of the present invention will be described in detail below with reference to the drawings.
[0017] Such as figure 1 As shown, the concentrator of the device of the present invention includes: a processing tank 9, a piston 10, a suction check valve 8, and an exhaust check valve 11. When the piston 10 moves upward, the suction check valve 8 is opened, the exhaust check valve 11 is closed, and the mist in the ultrasonic atomization tank 2 enters the processing tank 9; when the piston moves downward, the suction check valve 8 is closed , The mist in the treatment tank 9 is compressed and liquefied, and the exhaust check valve 11 is opened and discharged into the collection tank. The suction check valve and the exhaust check valve use spring-controlled mechanical check valves, and the opening pressure value of the check valve can be specifically determined as required.
[0018] The method for concentrating ethanol of the present invention adopts the above-mentioned ultrasonic atomization and concentration ethanol device. First, a pump can be used to pump the ethanol solution to be concentrated into the ultrasonic atomization tank 2 through the inlet 1 and reach a certain liquid level (the oscillator must be immersed in the solution), and the oscillator 3 is started to start ultrasonic atomization. After a certain period of time, the generated mist reaches a certain concentration in the upper part of the atomization tank, and the valve at the mist outlet 5 is opened, so that the mist outlet is connected with the mist inlet 6. The piston 10 in the processing tank 9 moves upwards to generate negative pressure in the processing tank. When the pressure in the tank is lower than the pressure of the gas at the inlet 6, the suction check valve 8 opens and the mist is sucked into the processing tank in. After the piston reaches the rear dead center, it moves downwards, the mist in the treatment tank is compressed, and the suction valve is closed due to the higher pressure. When the pressure in the treatment tank is greater than the pressure at the outlet 13 and the exhaust When the spring force of the one-way valve 8 is summed, the exhaust one-way valve is pushed open, and the concentrated ethanol solution collected by compression is discharged through the outlet 13. Under the action of pressure and position difference, the concentrated ethanol solution enters through the inlet 14 In the collection tank 15, and gather at the bottom of the collection tank. There is a small amount of uncondensed mist in the upper part of the collecting tank, which enters the packed tower 17 and is adsorbed on the packing. After reaching a certain amount, it slides down from the inner wall of the packed tower or the packing, returns to the collecting tank, and drops to Collect the bottom of the tank. After the ethanol stocked in the collection tank reaches a certain level, it is discharged through the product discharge port at the bottom of the collection tank.
