Description

Technical Field

[0001] The utility model relates to the technical field of fermented alcohol, in particular to a light wine recovery tower. Background Art

[0002] During the anaerobic fermentation process in the sealed alcohol fermentation tank, a large amount of fermentation exhaust gas rich in carbon dioxide will be produced. The carbon dioxide in the exhaust gas can be purified and then produced as a by-product. However, the alcohol content in the fermentation exhaust gas is not low. If it directly enters the subsequent carbon dioxide section, it will be consumed by impurities removal, resulting in this part of the fermented alcohol failing to be produced as a finished product, causing product loss and reduced output.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1 The utility model provides a technical solution: a light wine recovery tower, including a light wine recovery device cylinder 2, a light wine outlet 5 is fixedly installed at the middle position of the bottom of the light wine recovery device cylinder 2, and a multi-stage light wine recovery tower plate 7 is fixedly installed in the middle position inside the light wine recovery device cylinder 2, a raw gas inlet 3 is fixedly installed at the bottom position of the left end of the light wine recovery device cylinder 2, a heat exchanger 10 is fixedly installed at the middle position on the left side of the light wine recovery device cylinder 2, and a liquid level sensor 11 is fixedly installed at the bottom position on the right side of the light wine recovery device cylinder 2.

[0015] A device skirt 4 is fixedly mounted on the bottom of the cylinder 2 of the dilute wine recovery device, and a dilute wine outlet 5 extends to the outside of the device skirt 4 away from one end of the cylinder 2 of the dilute wine recovery device.

[0016] A gas outlet 9 is fixedly installed on the top of the cylinder 2 of the dilute wine recovery device, and an upper manhole 8 and a lower manhole 6 are fixedly installed at the top and bottom positions of the rear side of the gas outlet 9 respectively.

[0017] A primary water inlet 1 is fixedly installed at the top position of the left end of the cylinder 2 of the wine recovery device.

[0018] Light wine recovery device cylinder 2: As the main structure of the entire recovery tower, it provides space for gas and liquid to contact and react with each other. It ensures that the fermentation tail gas can effectively contact with the process water in the tower, thereby realizing alcohol recovery.

[0019] Light wine outlet 5: Located in the middle of the bottom of the cylinder, it is used to discharge the recovered alcoholic light wine. This location design helps to ensure that the recovered light wine can be discharged smoothly to avoid accumulation in the tower.

[0020] Multi-stage light wine recovery tray 7: The bubble tray design increases the contact area and time between gas and liquid, improving the adsorption efficiency of alcohol. The multi-stage design further enhances this effect, making alcohol recovery more efficient.

[0021] Raw gas inlet 3: Located at the bottom of the left end of the cylinder, it is the entrance for the fermentation tail gas to enter the light wine recovery tower. Reasonable inlet position design helps the gas to be evenly distributed in the tower and improves the recovery efficiency.

[0022] Heat exchanger 10: can recover heat and be used to preheat the raw gas entering the system or cool the exhaust gas. This can not only reduce energy consumption, but also improve the thermal efficiency of the system. The heat exchanger is installed on the side of the cylinder 2 of the light wine recovery device and is connected to the inside of the cylinder through a pipe. In this way, one end of the heat exchanger is not directly located in the cylinder, but indirectly exchanges heat with the hot fluid (such as light wine vapor or hot liquid) in the cylinder through a pipe system. This method is easy to install and maintain, and can reduce interference with the internal structure of the cylinder.

[0023] Liquid level sensor 11: used to monitor the liquid level of the light wine in the tower in real time, to ensure the normal operation of the tower and to discharge the recovered light wine in time.

[0024] Upper manhole 8 and lower manhole 6 are located at the top and bottom of the rear side of the tower top respectively, which are convenient for staff to enter the tower for inspection, maintenance and cleaning.

[0025] Primary water inlet 1: It is the inlet for process water to enter the dilute alcohol recovery tower. By adjusting the water inlet volume and water inlet speed, the reaction conditions in the tower can be controlled and the alcohol recovery effect can be optimized.

[0026] The light wine recovery tower is used to separate and recover alcohol from the fermentation tail gas, and the rest enters the subsequent carbon dioxide section to reduce alcohol loss. The specific process is as follows:

[0027] After the ethanol-containing fermentation tail gas is extracted from the fermentation tank, it enters the light wine recovery tower from the lower raw gas inlet 3. During the upward movement of the gas, it comes into contact with process water through the multi-stage light wine recovery tower plate 7 (bubble tower plate) and is adsorbed on its surface. It then flows to the bottom of the tower and is discharged through the bottom light wine outlet 5. The non-alcoholic carbon dioxide gas enters the next process from the top gas outlet 9, thereby recycling the ethanol-containing light wine.
