Technical Field

[0001] This utility model relates to the field of waste liquid treatment technology, and in particular to an alcohol waste liquid treatment device. Background Technology

[0002] Alcohol waste liquid is a byproduct of the fermentation process in alcohol or alcohol product production. Direct discharge of alcohol waste liquid can easily lead to water pollution, ecological damage, and resource waste. Therefore, how to treat alcohol waste liquid, such as through recycling, is an important research direction to promote the green transformation and upgrading of the alcohol industry.

[0003] Currently, the common technical solution for treating alcohol waste liquid is to use a large-scale distillation and cooling system to collect the alcohol and then use the same system to treat the waste liquid. This method has problems such as high operating costs, large footprint, and complex construction, and is not suitable for production scenarios with small alcohol consumption. Utility Model Content

[0004] Therefore, it is necessary to provide an alcohol waste treatment device to address the problems of high treatment costs and incompatibility with production scenarios with small alcohol consumption in current alcohol waste treatment solutions.

[0006] A dilution container; the dilution container stores a diluent;

[0007] An alcohol waste liquid delivery assembly connected to the inlet of the dilution container;

[0008] A gas delivery pipe connected to the outlet of the dilution container;

[0009] A filter assembly installed on the gas delivery pipeline;

[0010] Alcohol waste liquid is introduced into the dilution container through the alcohol waste liquid conveying assembly; the filtration assembly filters the volatile gas-liquid mixture in the dilution container to obtain alcohol gas; the alcohol gas is discharged through the gas conveying pipeline.

[0011] In one embodiment, the device further includes: a concentration detection component disposed on the gas delivery pipeline; the alcohol gas obtained after being filtered by the filter component flows through the concentration detection component via the gas delivery pipeline;

[0012] The concentration detection component detects the alcohol concentration of the flowing alcohol gas and alarms when the alcohol concentration of the alcohol gas exceeds the safe concentration threshold.

[0013] In one embodiment, the concentration detection component includes a concentration detection sensor and an alarm electrically connected to the concentration detection sensor;

[0014] The concentration detection sensor detects the alcohol concentration of the flowing alcohol gas, and sends an alarm command to the alarm device when the alcohol concentration of the alcohol gas exceeds the concentration safety threshold.

[0015] The alarm device responds to the alarm command and sounds an alarm.

[0016] In one embodiment, the alcohol waste liquid conveying assembly includes: an alcohol waste liquid conveying pipeline, and a first vacuum generator disposed on the alcohol waste liquid conveying pipeline;

[0017] The alcohol waste liquid is guided by the suction force generated by the first vacuum generator and introduced into the dilution container through the alcohol waste liquid delivery pipe.

[0018] In one embodiment, the device further includes:

[0019] A drain pipe is installed at the bottom of the dilution container, and a drain valve is installed on the drain pipe;

[0020] With the drain valve in the open position, the diluent in the dilution container is discharged from the dilution container through the drain pipe.

[0021] In one embodiment, the device further includes a second vacuum generator disposed on the gas delivery pipeline;

[0022] The gas-liquid mixture that evaporates in the dilution container is guided by the suction generated by the second vacuum generator from the dilution container into the gas delivery pipeline.

[0023] In one embodiment, the device further includes a liquid level detection component disposed on the dilution container.

[0024] In one embodiment, the liquid level detection component includes a liquid level observation tube disposed on the outer wall of the dilution container; a first end of the liquid level observation tube is connected to a cavity portion in the dilution container, and a second end is connected to the bottom of the dilution container.

[0026] The first liquid level sensor is located at the highest liquid level limit of the liquid level observation tube, and the second liquid level sensor is located at the lowest liquid level limit of the liquid level observation tube.

[0027] When the level of the diluent reaches the highest level limit of the level observation tube, the first level sensor will issue an upper level alarm; when the level of the diluent reaches the lowest level limit of the level observation tube, the second level sensor will issue a lower level alarm.

[0028] In one embodiment, the apparatus further includes a diluent delivery assembly connected to the diluent container via a diluent inlet.

[0029] The diluent is introduced into the diluent container from the diluent inlet through a diluent delivery assembly connected to the diluent container.

[0030] The aforementioned alcohol waste treatment device includes a dilution container for storing the diluent, an alcohol waste transport assembly connected to the inlet of the dilution container, a gas transport pipe connected to the outlet of the dilution container, and a filter assembly installed on the gas transport pipe. The alcohol waste is introduced into the dilution container through the alcohol waste transport assembly. During the dilution process, the alcohol waste may evaporate to produce a gas-liquid mixture. As the gas transport pipe exits the gas-liquid mixture from the dilution container, the filter assembly filters the mixture to obtain a low-concentration alcohol gas, which can then be discharged through the gas transport pipe. By diluting the alcohol waste, the risk of explosion caused by high-concentration alcohol waste can be effectively reduced, improving the safety of alcohol waste recovery. Furthermore, the entire device does not involve the construction of large-scale equipment; it only requires a simple connection and arrangement of the dilution container, waste transport assembly, gas transport pipe, and filter assembly to achieve safe treatment and recovery of alcohol waste.

[0045] See Figure 1 Figure 1 shows a schematic diagram of the structure of an alcohol waste liquid treatment device according to an embodiment of the present invention. The alcohol waste liquid treatment device provided in an embodiment of the present invention includes a dilution container 101, an alcohol waste liquid conveying assembly 102 connected to the liquid inlet 1011 of the dilution container 101, a gas conveying pipe 103 connected to the gas outlet 1012 of the dilution container 101, and a filter assembly 104 disposed on the gas conveying pipe 103.

[0046] The dilution container 101 is a carrier container for storing the diluent, which is an auxiliary treatment liquid used to dilute high-concentration alcohol waste. By mixing and diluting the alcohol waste with the diluent, the alcohol concentration of the alcohol waste can be effectively reduced, and its physicochemical properties can be adjusted to meet subsequent treatment requirements, such as recycling. It is understood that the diluent stored in the dilution container 101 can be any dilution medium capable of diluting alcohol waste, such as water or chemical reagent solutions. The specific shape and size of the dilution container 101 can be customized according to the actual application scenario, and this utility model does not limit this.

[0047] The alcohol waste liquid conveying assembly 102 is a conveying device used to deliver high-concentration alcohol waste liquid into the dilution container 101 for dilution. It provides a conveying path and power for the high-concentration alcohol waste liquid. The alcohol waste liquid conveying assembly 102 is connected to the inlet 1011 of the dilution container 101. It is understood that the alcohol waste liquid conveying assembly 102 can be any hardware component capable of introducing alcohol waste liquid into the dilution container 101.

[0048] In some embodiments, the alcohol waste liquid conveying assembly 102 may consist of an alcohol waste liquid conveying pipeline and a power supply component. The alcohol waste liquid conveying pipeline can provide a conveying path for the alcohol waste liquid, while the power supply component can provide conveying power for the alcohol waste liquid conveying pipeline. For example, the power supply component can be a waste liquid extraction pump.

[0049] In some embodiments, in order to reduce the danger of alcohol waste liquid during transportation, the alcohol waste liquid transportation component 102 can be inserted into the interior of the dilution container 101 through the inlet 1011 of the dilution container 101 and directly contact the diluent, thereby achieving the purpose of directly and accurately introducing high-concentration alcohol waste liquid into the diluent for safe dilution.

[0050] The gas delivery pipe 103 is a hardware component used to discharge the gas-liquid mixture generated during the evaporation of alcohol waste liquid, while maintaining the internal and external pressure balance of the dilution container 101. It is understood that even after dilution, alcohol waste liquid still retains a certain degree of volatility, generating a volatile gas-liquid mixture in the dilution container 101. If this mixture is not discharged in a timely manner, the internal pressure of the dilution container 101 may exceed the external pressure, posing a risk to its use. The gas delivery pipe 103 is connected to the gas outlet 1012 of the dilution container 101, providing a discharge channel for the volatile gas-liquid mixture in the dilution container 101. This stabilizes the internal and external pressure balance of the dilution container 101. Furthermore, since the volatile gas-liquid mixture is generated from diluted alcohol waste liquid, its alcohol concentration is much lower than that of undiluted alcohol waste liquid, eliminating any discharge risk.

[0051] The filter assembly 104, installed on the gas delivery pipeline 103, is a filter device used to filter the gas-liquid mixture to remove liquid carried in the mixture. By filtering the gas-liquid mixture, it can be ensured that the gas discharged from the gas delivery pipeline 103 is a low-concentration alcohol gas, improving the cleanliness of the gas emission. It is understood that the filter assembly 104 can be any hardware device capable of filtering liquid in the gas-liquid mixture; for example, the filter assembly 104 can be a cyclone separator, coalescing filter, baffle separator, membrane filter assembly, etc.

[0052] Specifically, the alcohol waste liquid generated during the production process can be introduced into the dilution container 101 through the alcohol waste liquid conveying component 102. The diluted alcohol waste liquid in the dilution container 101 will evaporate, and a gas-liquid mixture will be generated in the cavity part of the dilution container 101, that is, the part where the diluent does not reach. The gas-liquid mixture is conveyed from the dilution container 101 to the gas conveying pipe 103. The filter component 104 installed on the gas conveying pipe 103 will filter the gas-liquid mixture to obtain filtered alcohol gas. The alcohol gas continues to be discharged through the gas conveying pipe 103.

[0053] In some embodiments, the waste outlet of the gas conveying pipeline 103 can be connected to the waste gas treatment system of the production area. Alcohol gas enters the waste gas treatment system directly through the waste outlet of the gas conveying pipeline 103 for waste gas treatment, thereby reducing the safety of alcohol waste gas emissions while improving the cleanliness of gas emissions.

[0054] The alcohol waste liquid treatment device in the above embodiments includes a dilution container for storing diluent, an alcohol waste liquid conveying assembly connected to the inlet of the dilution container, a gas conveying pipe connected to the outlet of the dilution container, and a filter assembly installed on the gas conveying pipe. Alcohol waste liquid is introduced into the dilution container through the alcohol waste liquid conveying assembly. During the dilution process, the alcohol waste liquid may evaporate to generate a gas-liquid mixture. When the gas conveying pipe exits the gas-liquid mixture from the dilution container, the filter assembly can filter the gas-liquid mixture to obtain a low-concentration alcohol gas, which can then be discharged through the gas conveying pipe. By diluting the alcohol waste liquid, the risk of explosion caused by high-concentration alcohol waste liquid can be effectively reduced, improving the safety of alcohol waste liquid recovery. Moreover, the entire device does not involve the construction of large-scale equipment; it only requires a simple connection and arrangement of the dilution container, waste liquid conveying assembly, gas conveying pipe, and filter assembly to achieve safe treatment and recovery of alcohol waste liquid. Compared with traditional distillation and cooling recovery systems, it effectively reduces the treatment cost and construction complexity of alcohol waste liquid, and is better suited for production scenarios with small alcohol consumption.

[0055] In some embodiments, such as Figure 2 As shown, the alcohol waste treatment device also includes a concentration detection component 105 installed on the gas delivery pipeline 103. The alcohol gas obtained after filtration by the filter component 104 can flow through the concentration detection component 105 through the gas delivery pipeline 103. The concentration detection component 105 detects the alcohol concentration of the flowing alcohol gas and alarms when the alcohol concentration of the alcohol gas exceeds the safe concentration range.

[0056] The concentration detection component 105 is a hardware device used to detect the alcohol concentration of the flowing alcohol gas, obtain the alcohol concentration of the alcohol gas, and execute an alarm operation when the alcohol concentration exceeds the safe concentration range. The concentration detection component 105 is located after the filter component 104, which filters the input gas-liquid mixture to obtain filtered alcohol gas, which continues to flow along the gas delivery pipe 103 through the concentration detection component 105.

[0057] The concentration safety threshold is a preset threshold used to determine whether the concentration of alcohol gas exceeds the standard. Since the diluent is an auxiliary liquid used to dilute alcohol waste, if a large amount of alcohol waste is introduced, the diluent may dissolve too much of the waste, rendering it unable to dilute further. In this case, the diluent's dilution capacity reaches its limit, requiring the addition or replacement of the diluent to improve the overall dilution effect of the alcohol waste treatment device. The dilution capacity of the diluent can be characterized by the alcohol concentration of the alcohol gas; that is, the dilution capacity of the diluent is inversely proportional to the alcohol concentration of the alcohol gas. The stronger the dilution capacity, the lower the alcohol concentration of the gas, and vice versa.

[0058] Therefore, the dilution capacity limit of the diluent can be mapped to the concentration safety threshold. If the alcohol concentration of the alcohol gas exceeds the concentration safety threshold, it can be considered that the dilution capacity of the diluent in dilution container 101 has reached its limit and can no longer provide dilution for the alcohol waste liquid. In this case, it is necessary to add or replace the diluent to improve the overall alcohol waste liquid dilution effect of the alcohol waste liquid treatment device. If the alcohol concentration of the alcohol gas does not exceed the concentration safety threshold, it indicates that the diluent in dilution container 101 can still dilute the alcohol waste liquid.

[0059] Specifically, the filter component 104 in the device can filter the input gas-liquid mixture to obtain filtered alcohol gas. When the alcohol gas flows along the gas delivery pipe 103 to the concentration detection component 105, the concentration detection component 105 will detect the alcohol concentration of the alcohol gas, obtain the alcohol concentration value of the alcohol gas, and compare the alcohol concentration value with the preset concentration safety threshold. If the alcohol concentration value exceeds the concentration safety threshold, it means that the diluent in the dilution container 101 cannot dilute the alcohol waste liquid. The concentration detection component 101 will alarm, prompting that the diluent in the dilution container 101 needs to be added or replaced.

[0060] Understandably, the concentration detection component 105 can be any hardware device capable of detecting alcohol concentration and triggering alarms for concentration exceeding the specified range. In some embodiments, the concentration detection component 105 may include a concentration detection sensor and a user terminal connected to the concentration detection sensor. When the concentration detection component 105 determines that the alcohol concentration of the alcohol gas exceeds the safe concentration threshold, it can generate an alarm message and send the alarm message to the user terminal, prompting the user to add or replace the diluent in the dilution container 101.

[0061] In the above embodiments, by placing the concentration detection component after the filter component, the gas flowing through the concentration detection component is guaranteed to be pure alcohol gas without liquid, effectively reducing the risk of damage to the concentration detection component and improving the accuracy of alcohol concentration detection. Furthermore, by comparing the alcohol concentration with the safe concentration threshold, the changes in the dilution capacity of the diluent in the dilution container can be understood in a timely manner based on the comparison results, providing an accurate signal for diluent replacement.

[0062] In some embodiments, the concentration detection component includes a concentration detection sensor and an alarm electrically connected to the concentration detection sensor.

[0063] The concentration detection sensor is an electronic device used to detect the concentration of alcohol in a gas. Its core function is to convert the chemical signal of alcohol into a quantifiable electrical signal. The concentration detection sensor can detect the alcohol concentration of flowing alcohol gas, and if the alcohol concentration exceeds the safe concentration threshold, it sends an alarm command to the alarm device, instructing the alarm device to perform an alarm operation.

[0064] In some embodiments, the alcohol concentration detection sensor can be an electrochemical sensor, in which alcohol molecules diffuse into the electrolyte layer within the sensor and undergo an oxidation reaction on the surface of the catalytic electrode, generating a current signal proportional to the alcohol concentration, thereby enabling the detection of alcohol concentration.

[0065] In some embodiments, the alcohol concentration detection sensor can be a semiconductor oxide sensor, where alcohol molecules are adsorbed on the surface of a metal oxide, changing the material's resistance value. The alcohol concentration can be deduced from the change in resistance, thus achieving the detection of alcohol concentration.

[0066] In some embodiments, the alcohol concentration detection sensor can be an infrared spectral sensor, which utilizes the adsorption characteristics of alcohol molecules on specific infrared wavelengths to calculate the alcohol concentration through light intensity attenuation.

[0067] Among these, the alarm is a safety device used to issue warnings. By executing an alarm operation, it can quickly alert users to ensure the safety of alcohol waste disposal. Understandably, in alcohol waste disposal scenarios, alarms can use hardware devices with clear warning indications, such as buzzers or alarm indicator lights.

[0068] Specifically, after the filter assembly discharges the alcohol gas, the gas continues to flow through the gas transmission pipe into the concentration detection sensor. The sensor detects the concentration of the flowing alcohol gas, compares it to a safe concentration threshold, and generates an alarm command if the concentration exceeds the threshold. Upon receiving the alarm command, the alarm device immediately responds and executes the alarm operation.

[0069] In the above embodiments, by directly connecting the alarm to the concentration detection sensor, the alarm can react quickly and alert the user when the concentration detection sensor detects alcohol gas with an alcohol concentration exceeding the threshold, thereby improving the safety of alcohol waste liquid treatment.

[0070] In some embodiments, such as Figure 3 As shown, the alcohol waste liquid conveying assembly 102 includes an alcohol waste liquid conveying pipe 301 and a first vacuum generator 302 disposed on the alcohol waste liquid conveying pipe 301.

[0071] Among them, the alcohol waste liquid conveying pipeline 301 is a hardware device used to provide a conveying path for the alcohol waste liquid.

[0072] The first vacuum generator 302 is a power supply device used to provide conveying power for the transfer of alcohol waste liquid. Its principle is to use compressed air to generate a vacuum, forming a low-pressure area in the alcohol waste liquid conveying pipe 301, thereby drawing the alcohol waste liquid into the alcohol waste liquid conveying pipe 301 and introducing it into the dilution container 101 through the alcohol waste liquid conveying pipe 301.

[0073] Specifically, under the suction force generated by the first vacuum transmitter 302, the alcohol waste liquid is drawn into the alcohol waste liquid conveying pipe 301, and then introduced into the dilution container 101 through the alcohol waste liquid conveying pipe 301 to mix and dilute with the diluent.

[0074] In the above embodiments, by installing a first vacuum generator on the alcohol waste liquid conveying pipeline, a stable conveying power can be provided for the alcohol waste liquid conveying pipeline, thereby improving the continuity and stability of alcohol waste liquid conveying.

[0075] In some embodiments, such as Figure 4 As shown, the alcohol waste liquid treatment device also includes: a drain pipe 106 installed at the bottom of the dilution container 101, and a drain valve 107 installed on the drain pipe 106.

[0076] The drain pipe 106 is a liquid transport pipe used to discharge the diluent from the dilution container 101. When the dilution container 101 has completed the dilution of the alcohol waste liquid and needs to recover the diluent, or when the diluent needs to be replaced, the drain pipe 106 can be used to provide a discharge path for the diluent.

[0077] The drain valve 107 is a state-switching device used to control the flow of the drain pipe 106 between its on and off states. When it is necessary to control the drain pipe 106 to be open, the drain valve 107 can be adjusted to the open state, at which time the diluent can be discharged from the drain pipe 106. When it is necessary to control the drain pipe 106 to be closed, the drain valve 107 can be adjusted to the closed state, at which time the drain pipe 106 cannot be opened, and the diluent cannot be discharged. It can be understood that the drain valve 107 can be any type of valve capable of switching between on and off states, such as a ball valve, a solenoid valve, etc.

[0078] Specifically, if the alcohol waste treatment device has a need to discharge diluent, the drain valve 107 can be controlled to be in the open state. In this state, the diluent in the dilution container 101 can be discharged from the dilution container 101 through the open drain pipe 106.

[0079] In the above embodiments, by setting a drain pipe at the bottom of the dilution container and setting a corresponding drain valve for the drain pipe, a drain channel can be quickly provided for the discharge of the diluent when it is necessary to discharge the diluent in the dilution container, thereby improving the discharge rate and safety of the diluent.

[0080] In some embodiments, such as Figure 5 As shown, the alcohol waste treatment device also includes a second vacuum generator 108 installed on the gas delivery pipeline 103.

[0081] The second vacuum generator 108 is a power supply device used to provide power for the transmission of gas-liquid mixture and alcohol gas. Its principle is also to use compressed air to generate a vacuum, forming a low-pressure area in the gas transmission pipeline 103, thereby drawing the gas-liquid mixture from the dilution container 101 into the gas transmission pipeline 103 and providing power for the transmission of gas-liquid mixture and alcohol gas.

[0082] Specifically, the second vacuum generator 108 forms a low-pressure zone within the gas delivery pipe 103, drawing the gas-liquid mixture from the dilution container 101 into the gas delivery pipe 103. After the gas-liquid mixture is filtered by the filter assembly 104, alcohol gas is obtained, which is then discharged from the gas delivery pipe 103 under suction. It is understood that the specific location of the second vacuum generator 108 on the gas delivery pipe 103 is not limited in this embodiment, as long as it can provide the power to transport the gas-liquid mixture and the alcohol gas.

[0083] In the above embodiments, by installing a second vacuum generator on the gas delivery pipeline, a stable delivery power can be provided to the gas delivery pipeline, thereby improving the continuity and stability of the gas-liquid mixture and alcohol gas delivery.

[0084] In some embodiments, the alcohol waste treatment device further includes a liquid level detection component disposed on the dilution container.

[0085] The liquid level detection component is a detection device used to detect the liquid level of the diluent in the dilution container.

[0086] Specifically, the level detection component can accurately detect the level of the diluent in the dilution container and determine its exact height. By installing the level detection component on the dilution container, the position of the diluent level can be determined, providing a signal for subsequent replenishment and discharge of the diluent.

[0087] Furthermore, such as Figure 6 As shown, in some embodiments, the liquid level detection component includes a liquid level observation tube 601 disposed on the outer wall of the dilution container 101. The first end of the liquid level observation tube 601 is connected to the cavity portion in the dilution container 101, and the second end is connected to the bottom of the dilution container 101.

[0088] The liquid level observation tube 601, also known as a liquid level gauge or sight glass tube, is a device used to visually display the liquid level in a container. Through a transparent tube or window, the operator can directly observe changes in the liquid level. The principle of the liquid level observation tube 601 is the principle of communicating vessels. The liquid level observation tube 601 is connected to the bottom of the dilution container 101. Under the action of gravity, the liquid reaches equilibrium, and the liquid level inside the tube is consistent with the level inside the container.

[0089] The cavity is the part of the diluent above the dilution container 101 where the liquid level is not reached. Traditional liquid level observation tubes only need to be connected to the bottom of the container at one end to achieve the liquid level observation effect. However, in the case of alcohol waste liquid treatment, in order to reduce the possibility of alcohol evaporation gas being discharged through the liquid level observation tube and polluting the environment, the first end of the liquid level observation tube 601 is connected to the cavity in the dilution container 101. This allows alcohol evaporation gas to still enter the dilution container 101, and the dilution container 101 maintains stable internal and external air pressure through the air pressure delivery pipe 103, so there will be no inaccurate liquid level display.

[0090] Understandably, the transparent tube of the liquid level observation tube 601 can be made of materials such as glass, quartz glass, pressure-resistant plastic, or tempered glass.

[0091] Specifically, when the level of the diluent in the dilution container 101 changes, the user can intuitively observe the change in the level of the diluent through the level observation tube 601, providing an accurate signal for the replenishment and discharge of the diluent.

[0092] Furthermore, in some embodiments, such as Figure 7 As shown, the liquid level detection assembly also includes a first liquid level sensor 701 and a second liquid level sensor 702. The first liquid level sensor 701 is located at the highest liquid level limit of the liquid level observation tube 601, and the second liquid level sensor 702 is located at the lowest liquid level limit of the liquid level observation tube 601.

[0093] The first liquid level sensor 701 is used to detect the maximum limit of the diluent. By detecting the maximum limit of the diluent, it can effectively prevent the gas delivery pipeline 103 from sucking in excessive diluent, thus affecting the normal use of the pipeline. Understandably, the maximum liquid level limit on the liquid level observation tube 601 is the highest liquid level that ensures the gas delivery pipeline 103 will not suck in diluent.

[0094] The second liquid level sensor 702 is used to detect the minimum level of the diluent. By detecting the minimum level of the diluent, it can effectively prevent the alcohol waste liquid from being unable to be diluted properly due to insufficient diluent, thus affecting the treatment effect of the alcohol waste liquid. Understandably, the minimum liquid level limit on the liquid level observation tube 601 is the lowest liquid level that ensures the alcohol waste liquid can be diluted normally.

[0095] Specifically, when the level of the diluent reaches the maximum level limit of the level observation tube 601, the first level sensor 701 located at the maximum level limit will issue a level limit alarm, prompting the user that the current level of the diluent has exceeded the maximum level limit and that a certain amount of diluent may be drawn in when extracting the gas-liquid mixture, and whether it is necessary to discharge a certain amount of diluent.

[0096] When the level of the diluent reaches the minimum level limit of the level observation tube 601, the second level sensor 702 located at the minimum level limit will issue a lower level alarm, prompting the user that the current level of the diluent is below the minimum level limit and may not be able to provide normal waste liquid dilution effect, and whether it needs to be replenished.

[0097] In the above embodiments, by setting liquid level sensors at the key liquid level limits of the liquid level observation tube, namely the highest liquid level limit and the lowest liquid level limit, the functions of upper liquid level alarm and lower liquid level alarm can be further realized, reducing the risk of too much or too little diluent due to untimely observation by the user.

[0098] In some embodiments, the alcohol waste treatment apparatus further includes a diluent delivery assembly connected to the diluent container via a diluent inlet.

[0099] The diluent delivery assembly is a conveying device used to deliver the diluent into the dilution container, providing a delivery path and power for the diluent. The diluent delivery assembly is connected to the diluent inlet of the dilution container. It can be understood that the diluent delivery assembly can be any type of hardware capable of introducing diluent into the dilution container.

[0100] In some embodiments, the diluent delivery assembly may include a diluent delivery pipeline, a power supply component, and a delivery valve. The diluent delivery pipeline provides a delivery path for the diluent, the power supply component provides delivery power to the diluent delivery pipeline, and the delivery valve controls the switching between on and off states of the diluent delivery pipeline.

[0101] Specifically, when it is necessary to replenish or re-add the diluent, the diluent can be introduced into the diluent container from the diluent inlet through the diluent transfer component connected to the diluent container.

[0102] In the above embodiments, by setting up a diluent transfer component, the operational complexity of replenishing or replacing the diluent can be effectively reduced.

[0103] In some embodiments, such as Figure 8 As shown, an alcohol waste liquid treatment device 800 is provided, the device comprising:

[0104] Dilution container 101.

[0105] An alcohol waste liquid delivery pipe 301 is connected to the inlet of the dilution container 101.

[0106] A first vacuum generator 302 is installed on the alcohol waste liquid conveying pipeline 301.

[0107] Gas delivery pipe 103 connected to the outlet of dilution container 101.

[0108] The filter assembly 104, the second vacuum generator 108, and the concentration detection sensor 801 are installed on the gas delivery pipeline 103.

[0109] An alarm 802 is electrically connected to the concentration detection sensor 801.

[0110] A drain pipe 106 is installed at the bottom of the dilution container 101, and a drain valve 107 is installed on the drain pipe 106.

[0111] The liquid level observation tube 601 is installed on the outer wall of the dilution container 101, and the first liquid level sensor 701 is installed at the highest liquid level limit of the liquid level observation tube 601, and the second liquid level sensor 702 is installed at the lowest liquid level limit of the liquid level observation tube 601.

[0112] Specifically, the working steps of the alcohol waste liquid treatment device 800 include: First vacuum generator 302 is activated to generate suction in the alcohol waste liquid conveying pipe 301, drawing the alcohol waste liquid from the pipe 301 into the dilution container 101, which is pre-filled with purified water for dissolving and diluting the alcohol waste liquid. Second vacuum generator 108 is activated to generate a vacuum in the gas conveying pipe 103, extracting the volatile alcohol gas from the dilution container 101. The extracted gas-liquid mixture is filtered through the filter assembly 104 to remove the diluted liquid mixture, yielding alcohol gas. The alcohol gas flows through a concentration detection sensor 801, which detects the alcohol concentration. If the alcohol concentration exceeds the safety threshold, the sensor 801 sends an alarm command to the alarm 802, which emits an audible and visual alarm signal and can also output an electronic alarm signal. The user can adjust the drain valve 107 on the drain pipe 106 to the open state, opening the drain pipe 106 to discharge the diluted liquid that no longer has dilution capacity. Then replenish the dilution container 101 with new diluent to perform the dilution task.

[0113] If the alcohol concentration does not exceed the safe concentration threshold, the alcohol gas will be discharged through the waste outlet of the gas delivery pipeline 103 to the waste gas treatment system for waste gas treatment before being discharged.

[0114] During the device's operation, the user can observe the diluent level through the level observation tube 601. When the diluent level rises to the maximum level limit of the observation tube 601, the first level sensor 701 located at the maximum level limit will trigger an upper limit alarm, indicating to the user that the diluent level has exceeded the maximum level limit and that a certain amount of diluent may be drawn in during the extraction of the gas-liquid mixture, prompting the user to check if some diluent needs to be discharged. When the diluent level reaches the minimum level limit of the observation tube 601, the second level sensor 702 located at the minimum level limit will trigger a lower limit alarm, indicating to the user that the diluent level has fallen below the minimum level limit and may not provide a normal waste liquid dilution effect, prompting the user to check if replenishment is needed.

[0115] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0116] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
