Description

An alcohol fermentation waste gas treatment device Technical Field

[0001] This utility model relates to the field of alcohol fermentation waste gas treatment technology, specifically to an alcohol fermentation waste gas treatment device. Background Technology

[0002] Alcohol is an indispensable substance in daily life and industry. Alcoholic fermentation is a process in which microorganisms (such as yeast) decompose organic matter like glucose under anaerobic conditions, producing incompletely oxidized products such as alcohol and carbon dioxide, while releasing a small amount of energy. During alcoholic fermentation, waste gas is generated, containing acidic gases and odor molecules. Considering environmental protection requirements, this waste gas needs to be treated before being released into the air, necessitating an alcohol fermentation waste gas treatment device.

[0003] The existing patent, CN216703796U, entitled "Alcohol Fermentation Equipment and its Waste Gas Treatment Device," relates to the field of alcohol fermentation waste gas treatment technology. It discloses an alcohol fermentation equipment and its waste gas treatment device, which includes a first scrubbing tower. The input end of the first scrubbing tower is connected to a fermentation tank and a yeast tank, used to wash water-soluble molecules in the waste gas inside the fermentation tank and the yeast tank. Through the above technical solution, the alcohol fermentation equipment and its waste gas treatment device provided by this utility model removes water-soluble molecules from the waste gas by sequentially discharging it into the first and second scrubbing towers, then ionizing it with a first plasma device to separate odor molecules, and finally discharging it after washing in a third scrubbing tower. This three-stage washing and ionization process improves the waste gas treatment effect; simultaneously, the first fan can reduce and maintain the gas pressure, thereby ensuring the production conditions inside the fermentation tank and the yeast tank and reducing the energy consumption required for production.

[0004] The aforementioned device sequentially discharges waste gas into the first and second scrubbing towers to remove water-soluble molecules from the waste gas, then ionizes it through the first plasma device to separate odor molecules, and finally discharges it after being washed by the third scrubbing tower. However, some components of the waste gas can be recycled and reused, and direct treatment would result in resource waste and would not adequately meet people's needs. In view of the above situation, technological innovation is carried out on the basis of existing waste gas treatment devices. Summary of the Invention

[0005] The purpose of this invention is to provide an alcohol fermentation waste gas treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an alcohol fermentation waste gas treatment device, comprising an absorption tank and an inlet pipe, wherein a stirring blade is installed at the lower interior of the absorption tank, and a motor is installed below the stirring blade; the inlet pipe is installed on the upper left side of the interior of the absorption tank, and a one-way valve is installed inside the right side of the inlet pipe; a recovery pipe is connected to the lower left side of the inlet pipe, and a cooling pipe is installed around the middle left side of the inlet pipe.

[0007] Furthermore, a circulation pump is installed on the left side of the cooling pipe, and a cooler is installed above the circulation pump. The circulation pump drives the coolant in the cooling pipe, which has been cooled by the cooler, to circulate, thereby cooling a section of the intake pipe and causing volatile organic compounds such as ethanol in the exhaust gas to condense and flow out from the recovery pipe.

[0008] Furthermore, a sensor is installed in the upper center of the inside of the absorption tank, and the sensor is embedded in the absorption tank. The sensor detects the content of each component of the exhaust gas in the upper part of the absorption tank, thereby determining the consumption of the effective components in the absorption liquid, which facilitates timely replacement of the absorption liquid.

[0009] Furthermore, an exhaust pipe is installed on the right side of the absorption tank, and a second sensor is installed on the lower right side of the exhaust pipe. The second sensor ultimately detects whether the discharged exhaust gas meets the emission standards.

[0010] Furthermore, a backfire valve is installed inside the right side of the exhaust pipe, and a combustion chamber is installed below the backfire valve. The backfire valve prevents flame turbulence.

[0011] Furthermore, the combustion chamber is equipped with a flame nozzle, which is embedded in the combustion chamber. The exhaust gas is burned by the flame from the flame nozzle in the combustion chamber, effectively treating the VOCs (such as esters and organic acids) in the fermentation exhaust gas.

[0012] Furthermore, a filter tube is installed below the combustion chamber, and a sealing cap is rotatably connected to the front end of the filter tube. A latch is installed on one side of the sealing cap, and the sealing cap can be opened through the latch to facilitate quick replacement of the filter assembly.

[0013] Furthermore, a filter assembly is installed inside the filter tube, and the filter assembly includes a filter layer and an activated carbon layer. An activated carbon layer is installed on one side of the filter layer. The filter layer filters the flue gas particles in the exhaust gas, and the activated carbon layer adsorbs and purifies the trace amounts of alcohol and organic waste gas molecules that are not completely recovered.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the waste gas enters the absorption tank through the inlet pipe, the circulation pump drives the coolant cooled by the cooler in the cooling pipe to circulate, thereby cooling a section of the inlet pipe, so that the volatile organic compounds such as ethanol in the waste gas condense and liquefy and flow out from the recovery pipe for easy recovery. The waste gas enters the absorption tank, the motor drives the stirring blade to rotate, promote the mixing of the absorption liquid and the waste gas in the absorption tank, dissolve residual alcohol, etc., and the sensor one detects the content of each component of the waste gas in the upper part of the absorption tank to facilitate timely replacement of the absorption liquid. The waste gas is discharged through the exhaust pipe. The waste gas is burned by the flame of the nozzle in the combustion chamber, effectively treating the VOCs components (such as esters and organic acids) in the fermentation waste gas. The backfire valve prevents the flame from flowing turbulently. The waste gas then enters the filter pipe. The filter layer filters the smoke particles in the waste gas. The activated carbon layer adsorbs and purifies the trace amounts of alcohol and organic waste gas molecules that are not fully recovered. The sealing cover is opened by the latch, which facilitates quick replacement of the filter components. The sensor two finally detects whether the discharged waste gas meets the emission standards.

The circulation pump drives the coolant in the cooling pipe, which has been cooled by the cooler, to circulate, thereby cooling a section of the inlet pipe. This causes the volatile organic compounds such as ethanol in the waste gas to condense and liquefy and flow out from the recovery pipe for easy recovery.

An agitator 8 is installed at the lower interior of the absorption tank 1, and a motor 9 is installed below the agitator 8. The inlet pipe 2 is installed on the upper left side of the interior of the absorption tank 1, and a one-way valve 7 is installed inside the right side of the inlet pipe 2. A recovery pipe 3 is connected to the lower left side of the inlet pipe 2, and a cooling pipe 4 is installed around the middle left side of the inlet pipe 2. A circulation pump 5 is installed on the left side of the cooling pipe 4, and a cooler 6 is installed above the circulation pump 5. A sensor 10 is installed in the upper middle part of the interior of the absorption tank 1. The sensor 10 is embedded in the absorption tank 1. The exhaust gas enters the absorption tank 1 through the inlet pipe 2. The circulation pump 5 drives the coolant in the cooling pipe 4, which has been cooled by the cooler 6, to circulate, thereby cooling a section of the inlet pipe 2. This causes the volatile organic compounds such as ethanol in the exhaust gas to condense and liquefy and flow out from the recovery pipe 3 for easy recovery. The exhaust gas enters the absorption tank 1. The motor 9 drives the stirring blade 8 to rotate, promoting the mixing of the absorption liquid in the absorption tank 1 with the exhaust gas and dissolving residual alcohol, etc. The sensor 10 detects the content of each component of the exhaust gas in the upper part of the absorption tank 1 to facilitate timely replacement of the absorption liquid. The exhaust gas is discharged through the exhaust pipe 11.

[0022] As shown in Figures 1-3, an exhaust pipe 11 is installed on the right side of the absorption tank 1, and a sensor 2 19 is installed on the lower right side of the exhaust pipe 11. A flashback valve 12 is installed inside the right side of the exhaust pipe 11, and a combustion chamber 13 is installed below the flashback valve 12. A flame nozzle 14 is installed inside the combustion chamber 13, and the flame nozzle 14 is embedded in the combustion chamber 13. A filter pipe 15 is installed below the combustion chamber 13, and a sealing cap 16 is rotatably connected to the front end of the filter pipe 15. A latch 17 is installed on one side of the sealing cap 16. A filter assembly 18 is installed inside the filter pipe 15, and the filter assembly 18 includes a filter layer 1801. Activated carbon layer 1802 is installed on one side of filter layer 1801. The exhaust gas is burned by the flame of nozzle 14 in combustion chamber 13, effectively treating VOCs such as esters and organic acids in fermentation exhaust gas. Backfire valve 12 prevents flame turbulence. The exhaust gas then enters filter tube 15. Filter layer 1801 filters the flue gas particles in the exhaust gas. Activated carbon layer 1802 adsorbs and purifies the trace amounts of alcohol and organic waste gas molecules that are not completely recovered. Sealing cover 16 is opened by latch 17 to facilitate quick replacement of filter component 18. Sensor 2 19 finally detects whether the discharged exhaust gas meets the emission standards.

[0023] Working Principle: When using this alcohol fermentation waste gas treatment device, the waste gas first enters the absorption tank 1 through the inlet pipe 2. The circulation pump 5 drives the coolant cooled by the cooler 6 in the cooling pipe 4 to circulate, thereby cooling a section of the inlet pipe 2. This causes the volatile organic compounds such as ethanol in the waste gas to condense and liquefy, flowing out through the recovery pipe 3 for easy recovery. The waste gas then enters the absorption tank 1, where the motor 9 drives the stirring blade 8 to rotate, promoting the mixing of the absorbent liquid and waste gas in the absorption tank 1, dissolving residual alcohol, etc. Furthermore, the sensor 10 detects the content of various components in the waste gas at the top of the absorption tank 1 for timely updates. After the absorbent is replaced, the exhaust gas is discharged through the exhaust pipe 11. The exhaust gas is burned by the flame of the burner 14 in the combustion chamber 13, effectively treating the VOCs components such as esters and organic acids in the fermentation exhaust gas. The backfire valve 12 prevents flame turbulence. The exhaust gas then enters the filter pipe 15. The filter layer 1801 filters the flue gas particles in the exhaust gas. The activated carbon layer 1802 adsorbs and purifies the trace amounts of alcohol and organic waste gas molecules that are not completely recovered. The sealing cover 16 is opened by the latch 17 to facilitate quick replacement of the filter component 18. Finally, the sensor 19 detects whether the discharged exhaust gas meets the emission standards.
