Description

DETAILED DESCRIPTION OF THE INVENTION The unsuccessful example relates to an alcohol mortar processing apparatus for extracting alcohol from alcohol mortar and for layering a fermentation medium after alcohol extraction.

B. Prior art - When using this VC evaporator for extracting alcohol from alcohol, it is necessary to supply alcohol J to one driftwood passage of the evaporator and supply alcohol J to the other fluid passage M. By supplying a heating fluid such as steam to the alcohol 4 and exchanging heat between the two in the evaporator and heating the alcohol moromi, the alcohol contained in the alcohol 4 is converted into a gaseous state. The fermented coral from which the alcohol has been extracted is made into oil, which is then incinerated or dried for use in travelogues and the like.

However, when the above-mentioned gum was used to extract alcohol from alcoholic moromi, the following problem occurred. That is,
Because carbon dioxide gas is dissolved in the alcohol moromi along with the alcohol due to its splitting process, is it the alcohol in question?
When the image is directly supplied to the evaporator and the alcoholic moromi is heated,
At the same time as vapor containing alcohol is generated from alcohol 4, carbon dioxide gas is generated in the form of foam A, and this foaming causes inefficient heat exchange in the evaporator, resulting in stable evaporation of alcohol. There are many drawbacks such as not being able to do it.

7) When discharging alcohol from a conventional evaporator, the carbon dioxide in the alcohol 4 can be removed by leaving the alcohol at any place for a long time before supplying it to the evaporator. After carefully removing the
Alcohol moromi is supplied to the evaporator. However, with this method, the alcohol moromi had to stand still for a long time, and some people complained that the work efficiency was poor.Also, when extracting alcohol by the above method, the alcohol extracted from the evaporator and the vapor contained in it are cooled. Before leaving the station as alcohol drain, the superelectric is heated and pressurized by a compressor, etc., and this alcohol-containing vapor is used as a heat source for the evaporator, and then, in many cases, it is discharged as alcohol drain. .

When the vapor containing alcohol is reused as heat in this way, the following problems have arisen. That is, the vapor generated from the alcohol 4 contains both alcohol and water, resulting in a two-component vapor of alcohol and water. Therefore, the alcohol in the vapor (a
K VC will change the dew point and boiling point of the steam. Changes in dew point ((IXp) and bsp) with alcohol concentration are as shown in the graph shown in Figure 47.If we compare the C0 point and 02 point, which are the alcohol content, we can see that the alcohol content is low. Dew point of point C1 (4, II'
) and the boiling point (2z, p), the temperature difference ΔT1 is smaller than the difference ΔT2 between the dew point (d·p) and the boiling point cb, p) of C, 4, which has a high alcohol content. By the way, after raising the external pressure and temperature of the vapor containing the alcohol, it is sent to the evaporator,
When used as a heat source, the vapor is condensed in the evaporator and discharged as a liquid, so the drop in the level of noise at the output from the evaporator inlet is due to the alcohol content mentioned above. The difference Δ between the dew point (d%p) and the boiling point ('b, ri) of gold-containing steam is TiC4.The smaller this temperature drop is, the larger the difference in heat transfer d!L degree in the evaporator can be. It will be a poem that will carry out all the exchanges.

Therefore, the mixed vapor of alcohol and water supplied to the evaporator will be more effective if the temperature difference is larger as the alcohol level is lower, but the alcoholic moromi will be supplied directly to the evaporator. In particular, if the obtained vapor is compressed and reused as a heat source for the evaporator, the alcohol content will be too high, making it difficult to maintain a large difference in heat transfer INA.
However, there were many problems such as inefficient heat exchange.

Conventionally, the heat transfer area of the evaporator was increased to compensate for this low efficiency, but increasing the heat transfer area resulted in the evaporator becoming larger and more expensive. Purpose When extracting alcohol from alcoholic moromi, alcohol rIJk can be extracted without removing carbon dioxide from the alcoholic moromi by allowing it to stand for a long time.
When the two-component vapor of the alcohol extracted from the alcoholic moromi and the water is heated to an external pressure using a congremboux 4fK and then reused as a heat source for the evaporator. This makes it possible to use low alcohol content vapor as a heat source.

C. arR of the invention.

The alcohol processing equipment is used to evaporate the alcohol and carbon dioxide gas present in the alcohol directly into a vacuum state, and at the same time remove the carbon dioxide bubbles generated on the liquid surface of the alcohol moromi as described above. 7. VC grooves were formed so that they could be erased by spraying alcohol moromi onto the liquid.

An alcohol evaporator (8) is discharged from the alcohol, and a humprenbu (9) is used to raise the pressure and temperature of the alcohol-containing steam generated in the evaporator (8) and use it as a heat source for the evaporator (8). ) and an exhaust heat recovery device (7) for heating the alcohol mash sent from the seven run tank (2) to the evaporator (8) by the alcohol drain discharged from the evaporator (8). This is the next thing.

Embodiment Fig. 2 is a diagram showing an alcohol processing apparatus according to the present invention.The apparatus shown in this figure is a 7-run tank in which the alcoholic moromi is heated to a predetermined temperature and then completely depressurized. After the alcohol and carbon dioxide directly in the alcohol are self-evaporated in the 7-run tank, and the alcohol mortar after the alcohol and carbon dioxide have been self-evaporated is sent to the evaporator to extract the P1 alcohol. This is to concentrate Alcohol J whose alcohol concentration has decreased.

In the figure, (1) is the 4th heater for heating the alcoholic moromi to a predetermined temperature, and (2) is the 4th heater that heats the alcoholic moromi to a predetermined temperature. This is a 7-run tank for self-evaporation of alcohol and carbon dioxide. The 7-run pump tank (2) is connected to a vacuum generator (5) via a cooling condenser (3) and a 5 g/liquid separator (4). The air pressure in the tank (2) C is reduced. Also, inside the 7 run tank (2), when supplying alcohol mash into the 7 run tank (2), there is a nozzle (2) that sprays the alcohol mash and attaches it next to the 1st part of the 7 run tank (2). 2a)
But i7 is 6. (6) is a vent condenser for preheating the alcoholic moromi discharged from the 7-run system (2), and (7) is a vent condenser? - further heating the alcohol preheated by 61/in the exhaust heat recovery device 6), the vent condenser (6) and the waste heat recovery device (7) are connected to the evaporator (8), which will be described later. The alcohol-containing liquid and gas that are often discharged are used as a heat source. (8) extracts the alcohol content remaining in the alcohol immediately discharged from the 7 run tank (2), and also extracts the f! The evaporator (9) for concentrating the R fermentation medium is used to raise the external pressure and temperature of the alcohol-containing vapor generated in evaporation 4 (8) C.
This is a combination wrench for reusing this steam as a heat source for the evaporator (8). 0@ is a waste heat recovery device (7) that collects the alcohol-containing liquid discharged from the evaporator (8).
a second gas-liquid separator (1) for sending the liquid ρλ to the vapor gold vent condenser (6);
This is the ninth third gas-liquid separator that sends the alcohol-containing liquid discharged from the vent condenser (6) to the second gas-liquid separator mentioned above. α4 is a vacuum generator connected to the vent condenser (6) and the third gas-liquid separator (lυ). , Also, in order to concentrate the fermentation material after alcohol has been extracted, first supply steam to the heater + 11 for 4, and water to the condenser (3).
The inside of the seven run tank (2) is kept in a vacuum state by the vacuum generator (5). When this confused alcohol 4 is sent to the 4 heater +11, the alcohol fs is sent to the 4 heater fl) 4f! by steam fr
It is heated to a constant temperature.

The heated alcohol is then supplied in the form of a spray into the 7-lush tank (2) through a nozzle (2a) provided in the 7-lush tank (2). Then, since the inside of the 7-lush tank (2) is in a vacuum state, the alcohol and carbon dioxide dissolved in alcohol 1 self-evaporate, and the alcoholic moromi turns into 4'A containing alcohol and charcoal. Gas is generated.At this time,
The alcoholic mash that is supplied into the 7-lush tank (2) is processed by the action of the nozzle (2a) provided in the 7-lush tank (2), so that the alcoholic mash that is stored at the bottom of the 7-lush tank (2) is mixed into the (shaped surface). Because it rotates and sprays, the bubbles that are generated when carbon dioxide gas is generated from the liquid surface of alcohol j are eliminated by the alcohol moromi that is sprayed.Therefore, the bubbles that are generated when carbon dioxide gas is generated inhibit the evaporation of alcohol. There's nothing to worry about.

The alcohol vapor and carbon dioxide gas generated in the 7-run tank (2) in this way are sent to the cooling condenser (3), where they are cooled by the flowing water. After that, the first gas-liquid separator (+l
K is sent. Then, the alcohol that has been cooled and turned into a liquid inside the condenser-r-(a) is discharged to the outside as an alcohol drain in the high equipment, and the charcoal and dredging gas are exhausted into the atmosphere◇Also, the flash tank (2) The alcohol I moromi (from which the alcohol content and most of the carbon dioxide gas have been separated) is sent to the vent condenser ((3) and exhaust heat recovery 4 (
7) The whole is sent to the evaporator (8). and the evaporator (
The alcohol-containing vapor generated from the alcohol mash in the evaporator (8) is heated to 4 pressure M by the compressor (9)G, and then supplied to the evaporator (8) as a heat source for the evaporator (8). It is used to heat the alcohol t6 that is delivered to the body. In addition, the liquid rod containing alcohol discharged from the evaporator (8) in a liquid state is transferred to the third gas-liquid separator 1.

When the above circulation cycle is completed by the alcohol mash discharged from the 7 run tank (2), the alcohol mash discharged from the 7 run tank (2) is transferred to the vent condenser tank (6). and exhaust heat recovery device (7
) is heated to a predetermined temperature by the evaporator (8) 丙Vζ
In the evaporator (8), the alcohol content remaining under pressure in the alcohol drain is extracted from the alcoholic moromi, and after the alcohol has been extracted, the alcoholic medium is left unused. is discharged. At this time, the evaporator (8
) Since the alcoholic moromi supplied to the tank does not contain carbon dioxide, no carbon dioxide gas VCX light pond damage will occur. Also, the evaporator (alcohol content generated in Gennai?: Aimu evaporator) is heated to external pressure with the compressor (9).
My theory is that when used as a heat source for the evaporator (8), the alcohol concentration of the vapor is low, so this vapor is used as a heat source for the evaporator (8).
The condensation inside the evaporator + g) The humidity drop at the outlet compared to the inlet is small, allowing for a large p1 temperature chamber. Therefore, excellent heat exchange can be performed.

In addition, the heater f for 1 of the above-mentioned alcohol I wound treatment device

E. Effects of the Invention After immediately heating the above-mentioned alcoholic moromi to a predetermined temperature, it is supplied into a Franch tank with the interior in a vacuum state, and the alcohol and carbon dioxide dissolved in the alcohol 1 are removed by self-evaporation. As it separates from the alcoholic moromi, carbon dioxide bubbles C are generated on the liquid surface of the alcoholic moromi.
1 By spraying alcohol moromi on the above liquid surface, the carbon dioxide gas dissolved in the alcohol can be degassed in a short time, and at the same time, the bubbles generated by the generation of carbon dioxide gas can be removed. In order to prevent the self-evaporation of alcohol from being inhibited, if the alcohol from which a certain amount of alcohol and most of the carbon dioxide have been separated in the flash tank is sent to the evaporator and condensed, carbon dioxide will be added to the evaporator. Gas is not generated in the form of foam, and the alcohol remaining in Alcohol J can be stably evaporated.

Further, since the alcohol concentration of the vapor containing alcohol generated in the evaporator is low, the vapor is suitable for use as a heat source of evaporated vapor after being pressurized and heated by a compressor.

For example, if alcohol δ is supplied to the evaporator without deaeration using a rj 7 run tank, then the vapor generated in the evaporator that removes the alcohol content is
When QC5Q pressure is used as a heat source, the alcohol content of the vapor is //% oak, so the dew point of this vapor is i da 1. J> QC1 boiling point is 77. ,f'C
Therefore, the heat source steam temperature decreases by 1d, 7. It becomes j°C. On the other hand, when the alcoholic mash that has been deaerated by the 7 lash tank is supplied to the evaporator, the alcohol concentration of the vapor containing alcohol generated in the evaporator is 2%. As above, this steam is
What is the dew point when the pressure is reduced to S? , 50G, boiling 2 silver is 77°
