Description

Technical Field

[0001] This application relates to the field of beer production technology, and in particular to a beer wastewater treatment device and a beer production line. Background Technology

[0002] Beer is produced by pulverizing raw materials using a pulverizing device, which then transports the pulverized materials to the brewing unit for saccharification and fermentation. The brewing wastewater discharged from the brewing unit contains organic pollutants and must be transported to a wastewater treatment plant for purification to prevent environmental pollution.

[0003] In related technologies, wastewater treatment devices include an anaerobic tank, an aerobic tank, and a sludge tank. The outlet ends of the aerobic tank and the anaerobic tank are connected. A sludge discharge structure is installed in the anaerobic tank, and the outlet end of the sludge discharge structure is connected to the sludge tank. Wastewater enters the anaerobic tank and reacts to decompose large organic molecules into small organic molecules, which are then transported to the aerobic tank. Through aerobic respiration, the small organic molecules are completely oxidized and decomposed to form a clear liquid that is discharged. The generated sludge is transported to the sludge tank through the sludge discharge structure.

[0004] However, during wastewater treatment, some sludge settles and accumulates at the sludge inlet of the sludge discharge structure, which can prevent the sludge from entering the sludge discharge structure and being discharged from the anaerobic tank, thus affecting the wastewater treatment effect. Utility Model Content

Along the direction away from the main mud discharge pipe, the distance between adjacent mud inlet holes gradually decreases, and the diameter of the mud inlet holes gradually increases. The distance between adjacent mud inlet holes is greater than or equal to 600 mm and less than or equal to 1500 mm, and the diameter of the mud inlet holes is greater than or equal to 30 mm and less than or equal to 40 mm.

[0011] In one possible implementation, the anaerobic tank includes an anaerobic tank body and a pipe trench connected to the side wall of the anaerobic tank body. The sludge discharge main pipe and the circulation main pipe are both located in the pipe trench, and the sludge discharge branch pipe and the circulation water distribution branch pipe are both located at the bottom of the anaerobic tank body.

[0012] In one possible implementation, an aerobic tank is further included, which is connected to the outlet of the anaerobic tank. The aerobic tank is used to further oxidize and decompose the remaining organic matter in the wastewater to be treated in the anaerobic tank. An aeration structure is provided in the aerobic tank to introduce air into the wastewater to be treated. The aeration structure includes an aeration main pipe, multiple aeration pipes, and multiple connecting pipes.

[0042] As shown in the background art, in related technologies, wastewater treatment devices include an anaerobic tank, an aerobic tank, and a sludge tank. The outlet ends of the aerobic tank and the anaerobic tank are connected. A sludge discharge structure is installed in the anaerobic tank, and the outlet end of the sludge discharge structure is connected to the sludge tank. Wastewater enters the anaerobic tank and reacts to decompose large organic molecules into small organic molecules, which are then transported to the aerobic tank. Through aerobic respiration, the small organic molecules are completely oxidized and decomposed to form a clear liquid that is discharged. The generated sludge is transported to the sludge tank through the sludge discharge structure.

[0043] However, during the wastewater treatment process, some sludge settles and accumulates at the sludge inlet of the sludge discharge structure, which can prevent the sludge from entering the sludge discharge structure and being discharged from the anaerobic tank, thus affecting the wastewater treatment effect.

[0044] To address the aforementioned technical problems, this application provides a beer wastewater treatment device and a beer production line, comprising: an anaerobic tank for decomposing organic matter in the wastewater to be treated; a sludge discharge structure including multiple sludge discharge branch pipes spaced apart within the anaerobic tank, each branch pipe having multiple sludge inlet holes, configured such that sludge generated during the decomposition of organic matter in the wastewater enters the sludge discharge branch pipes through the sludge inlet holes and is discharged from the anaerobic tank; and a circulating water distribution structure including multiple circulating water distribution branch pipes spaced apart within the anaerobic tank body, with the sludge discharge branch pipes positioned between adjacent circulating water distribution branch pipes, each branch pipe having multiple water distribution holes for spraying wastewater towards the sludge inlet holes to disperse the sludge accumulated at the sludge inlet holes, allowing the sludge in the anaerobic tank to smoothly enter the sludge discharge branch pipes through the sludge inlet holes and be discharged from the anaerobic tank, thereby improving the quality of anaerobic treatment.

[0045] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0046] In a first aspect, embodiments of this application provide a beer wastewater treatment device, combined with Figures 1 to 5 As shown, it includes: an anaerobic tank 100, which is used to decompose organic matter in the wastewater to be treated.

[0047] The sludge discharge structure 300 includes multiple sludge discharge branch pipes 320, which are spaced apart within the anaerobic tank 100. Each sludge discharge branch pipe 320 has multiple sludge inlet holes 321. The sludge discharge branch pipes 320 are used to allow sludge generated during the decomposition of organic matter in the wastewater to be treated in the anaerobic tank 100 to enter the sludge discharge branch pipes 320 through the sludge inlet holes 321 and then discharge it from the anaerobic tank 100.

[0048] The circulating water distribution structure 400 includes multiple circulating water distribution branch pipes 420, which are spaced apart within the anaerobic tank 100 body. Sludge discharge branch pipes 320 are located between adjacent circulating water distribution branch pipes 420. The pipe wall of each circulating water distribution branch pipe 420 has multiple water distribution holes 421, which are used to spray wastewater to be treated toward the sludge inlet hole 321.

[0049] Understandably, in combination Figures 1 to 5As shown, the anaerobic tank 100 can be equipped with a sludge discharge structure 300 and a circulating water distribution structure 400. The circulating water distribution structure 400 is used to transport the wastewater to be treated into the anaerobic tank 100, where it is fully mixed and reacted with the anaerobic bacteria in the anaerobic tank 100. This process decomposes the large molecular organic matter in the wastewater into small molecular organic matter, which is then discharged into the aerobic tank 200 for further oxidation and decomposition. During the reaction process in the anaerobic tank 100, sludge impurities are generated. The sludge discharge structure 300 can be used to discharge the sludge outside the anaerobic tank 100, removing the sludge and preventing it from hindering the reaction of the wastewater to be treated, thus ensuring the quality of anaerobic treatment.

[0050] However, some sludge easily settles and accumulates at the sludge inlet of the sludge discharge structure 300, which can prevent the sludge from entering the sludge discharge structure 300 and being discharged from the anaerobic tank, thus affecting the quality of anaerobic treatment.

[0051] Specifically, in combination Figures 1 to 5 As shown, multiple circulating water distribution branch pipes 420 of the circulating water distribution structure 400 can be spaced apart within the anaerobic tank 100, and the sludge discharge branch pipes 320 of the sludge discharge structure 300 can be placed between adjacent circulating water distribution branch pipes 420. Each sludge discharge branch pipe 320 has multiple sludge inlet holes 321. Sludge enters the sludge discharge branch pipe 320 through the sludge inlet holes 321 and is discharged outside the anaerobic tank 100 through the sludge discharge branch pipes 320. The wastewater to be treated within the circulating water distribution branch pipes 420 can be sprayed from the water distribution holes 421 to the sludge inlet holes 321, which not only removes accumulated wastewater but also... The sludge at the sludge inlet 321 is dispersed so that the sludge in the anaerobic tank 100 can smoothly enter the sludge discharge branch pipe 320 through the sludge inlet 321 and be discharged from the anaerobic tank 100, thereby improving the quality of anaerobic treatment. Moreover, since the adjacent circulating water distribution branch pipes 420 spray the wastewater to be treated towards the middle, under the action of hydraulic force, a vortex is easily formed, which can stir the wastewater to be treated in the anaerobic tank 100 and prevent some sludge from settling and accumulating at the sludge inlet 321 of the sludge discharge branch pipe 320, causing the sludge discharge function of the sludge discharge structure 300 to fail.

[0052] It should be noted that, in combination Figure 3 As shown, the circulating water distribution branch pipe 420 has multiple water distribution holes 421 on its pipe wall. The water distribution holes 421 are staggered along the axial direction of the circulating water distribution branch pipe 420, which can spray the wastewater to be treated in multiple directions, so that the water distribution effect of the anaerobic tank 100 is more uniform, so that the wastewater to be treated can fully react with the anaerobic bacteria in the anaerobic tank 100, and avoid uneven distribution of the sludge generated by the reaction.

[0053] In one possible implementation, combining Figure 1 and Figure 2 As shown, the circulating water distribution structure 400 also includes a circulating main pipe 410 and a dredging pipe 440.

[0054] The main circulation pipe 410 is connected to multiple circulating water distribution branch pipes 420. A circulation pump 430 is installed on the main circulation pipe 410. The circulation pump 430 is used to continuously circulate and transport the wastewater to be treated to the circulating water distribution branch pipes 420.

[0055] The inlet of the unblocking pipe 440 is connected to the circulating water distribution branch pipe 420 through a tee interface. The sludge discharge structure 300 is equipped with a backwash interface. The outlet of the unblocking pipe 440 is connected to the backwash interface. A control valve 441 is installed on the unblocking pipe 440. A regulating valve 422 is installed on the circulating water distribution branch pipe 422. The regulating valve 422 is located along the direction of the wastewater to be treated and away from the tee interface.

[0056] Specifically, in combination Figure 1 and Figure 2 As shown, the circulating water distribution branch pipe 420 can be a U-shaped pipe with the same horizontal height. The U-shaped port of the circulating water distribution branch pipe 420 is connected to the circulating main pipe 410. A circulating pump 430 is installed on the circulating main pipe 410. The circulating pump 430 can continuously circulate and transport the wastewater to be treated to the circulating water distribution branch pipe 420.

[0057] In addition, a T-junction is installed near the U-shaped port of the circulating water distribution branch pipe 420. The T-junction is connected to one end of the unclogging pipe 440, and the other end of the unclogging pipe 440 is connected to the backwashing interface provided on the sludge discharge structure 300. A control valve 441 is installed on the unclogging pipe 440, and a regulating valve 422 is installed on the circulating water distribution branch pipe 420. The regulating valve 422 is located along the direction of the wastewater to be treated and away from the T-junction.

[0058] It should be noted that during normal water distribution to the anaerobic tank 100, control valve 441 is closed, and circulation pump 430 and regulating valve 422 are opened. The wastewater to be treated flows through the main circulation pipe 410 to the circulation distribution branch pipe 420, and then is sprayed into the anaerobic tank 100 through the distribution hole 421. When the sludge discharge structure 300 is blocked, control valve 441 and circulation pump 430 are opened, and regulating valve 422 is closed, allowing the wastewater to be treated to flow through the main circulation pipe 410 to the unblocking pipe 440, enter the backwash interface, and be injected into the sludge discharge structure 300 for backwashing to prevent blockage. Of course, flushing agent can also be injected to backwash the sludge discharge structure 300 for better cleaning effect.

[0059] Of course, in other implementations, refer to Figure 2 As shown, a check valve 460 is also installed on the circulation header 410 to prevent backflow.

[0060] In one possible implementation, combining Figure 1 and Figure 2As shown, the circulating water distribution structure 400 also includes a circulating water inlet pipe 450. The input end of the circulating water inlet pipe 450 is connected to the anaerobic tank 100, and the output end of the circulating water inlet pipe 450 is connected to the inlet end of the circulating pump 430.

[0061] Specifically, in combination Figure 1 and Figure 2 As shown, a circulating water inlet pipe 450 can also be installed. The input end of the circulating water inlet pipe 450 is connected to the anaerobic tank 100, and the circulating water inlet pipe 450 is connected to the circulating main pipe 410. When it is not necessary to inject new wastewater into the anaerobic tank 100, the inlets of the circulating pump 430 and the circulating water inlet pipe 450 can be opened, and the inlet of the circulating main pipe 410 can be closed. Under the action of the circulating pump 430, the original wastewater to be treated in the anaerobic tank 100 is sucked into the circulating water inlet pipe 450, flows into the circulating main pipe 410, and is then transported through the circulating main pipe 410 to the circulating water distribution branch pipe 420. The wastewater is then injected back into the anaerobic tank 100 through the water distribution hole 421, forming a circulation, which facilitates the uniform mixing of the wastewater to be treated with the anaerobic bacteria.

[0062] In one possible implementation, combining Figure 1 , Figure 2 and Figure 4 As shown, the sludge discharge structure 300 also includes a sludge discharge main pipe 310, which is arranged in parallel with the circulation main pipe 410. Multiple sludge discharge branch pipes 320 are connected to the sludge discharge main pipe 310. A backwashing interface is provided on the sludge discharge main pipe 310, and a valve 322 is installed on the sludge discharge branch pipes 320.

[0063] Specifically, in combination Figure 1 , Figure 2 and Figure 4 As shown, the sludge discharge main pipe 310 is arranged in parallel with the circulation main pipe 410. Multiple sludge discharge branch pipes 320 are connected to the sludge discharge main pipe 310. The pipe end of the sludge discharge main pipe 310 is connected to the sludge tank (not shown in the figure). The multiple sludge discharge branch pipes 320 discharge the sludge in the anaerobic tank 100 to the sludge discharge main pipe 310, and then discharge it to the sludge tank for centralized treatment.

[0064] The sludge discharge main pipe 310 is equipped with a backwashing interface, and the unblocking pipe 440 is connected to the sludge discharge main pipe 310 through the backwashing interface to backwash the sludge discharge main pipe 310 and the sludge discharge branch pipe 320, ensuring that the sludge discharge structure 300 is unobstructed. Furthermore, a valve 322 can be installed on the sludge discharge branch pipe 320 to control the flow rate of the discharged sludge.

[0065] Furthermore, refer to Figure 4 and Figure 5As shown, multiple mud inlet holes 321 are spaced apart on the peripheral wall of the mud discharge branch pipe 320. Along the direction away from the main mud discharge pipe 310, the spacing between adjacent mud inlet holes 321 decreases step by step, and the diameter of the mud inlet holes 321 increases step by step. The spacing between adjacent mud inlet holes 321 is greater than or equal to 600 mm and less than or equal to 1500 mm, and the diameter of the mud inlet holes 321 is greater than or equal to 30 mm and less than or equal to 40 mm.

[0066] Specifically, in combination Figure 4 and Figure 5 As shown, multiple sludge inlet holes 321 are provided on the periphery of the sludge discharge branch pipe 320. The sludge inlet holes 321 are spaced apart, with the diameter of the sludge inlet hole 321 being smaller and the spacing between adjacent sludge inlet holes 321 being larger the closer they are to the sludge discharge main pipe 310. It can be understood that the smaller the diameter of the sludge inlet hole 321, the less likely sludge is to enter the sludge discharge branch pipe 320, while the closer it is to the sludge discharge main pipe 310, the easier it is for sludge to be discharged through the sludge discharge main pipe 310. This arrangement, with reasonable settings for the diameter and spacing of the sludge inlet holes 321, ensures that the amount of sludge discharged in each area of ​​the anaerobic tank 100 is equal, achieving uniform sludge discharge and avoiding sludge accumulation in some areas, thereby preventing blockage of the sludge discharge structure 300.

[0067] In one possible implementation, combining Figure 1 , Figure 2 and Figure 4 As shown, the anaerobic tank 100 includes an anaerobic tank body 110 and a pipe trench 120 connected to the side wall of the anaerobic tank body 110. The sludge discharge main pipe 310 and the circulation main pipe 410 are both located in the pipe trench 120, and the sludge discharge branch pipe 320 and the circulation water distribution branch pipe 420 are both located at the bottom of the anaerobic tank body 110.

[0068] Specifically, in combination Figure 1 , Figure 2 and Figure 4 As shown, the sludge discharge branch pipe 320 and the circulating water distribution branch pipe 420 are both located at the bottom of the anaerobic tank body 110. This not only facilitates the discharge of sludge and prevents sludge from sinking into dead corners within the anaerobic tank body 110, but also enhances the uniformity of water distribution within the anaerobic tank body 110 by distributing and stirring water from the bottom, allowing the wastewater to be treated and the anaerobic bacteria within the anaerobic tank body 110 to be fully mixed.

[0069] The anaerobic tank body 110 has a pipe trench 120 connected to its side wall. The sludge discharge main pipe 310 and the circulation main pipe 410 are both located in the pipe trench 120 to facilitate timely inspection of the sludge discharge main pipe 310 and the circulation main pipe 410 for blockage and leakage.

[0070] In one possible implementation, combining Figure 6 and Figure 7As shown, it also includes an aerobic tank 200, which is connected to the outlet of the anaerobic tank 100. The aerobic tank 200 is used to further oxidize and decompose the remaining organic matter in the wastewater to be treated in the anaerobic tank 100. An aeration structure 500 is provided in the aerobic tank 200, which is used to introduce air into the wastewater to be treated. The aeration structure 500 includes an aeration main pipe 510, multiple aeration pipes 520, and multiple connecting pipes 530. The connecting pipes 530 are connected to the aeration main pipe 510 and are spaced apart along the extension direction of the aeration main pipe 510. The multiple aeration pipes 520 are connected to the connecting pipes 530 and are spaced apart along the extension direction of the connecting pipes 530.

[0071] Understandably, in combination Figure 6 and Figure 7 As shown, the outlets of the aerobic tank 200 and the anaerobic tank 100 are connected. The anaerobic tank 100 reacts with anaerobic bacteria to decompose the large molecular organic matter in the wastewater to be treated into small molecular organic matter, which is then discharged into the aerobic tank 200. The aeration structure 500 in the aerobic tank 200 can introduce air into the wastewater to be treated, so that the small molecular organic matter in the wastewater to be treated can be oxidized and decomposed to form a clear liquid.

[0072] Specifically, in combination Figure 6 and Figure 7 As shown, multiple connecting pipes 530 extend vertically from the top to the bottom of the aerobic tank 200. The input ends of all connecting pipes 530 are connected to the main aeration pipe 510, and the connecting pipes 530 are spaced apart along the extension direction of the main aeration pipe 510. Multiple aeration pipes 520 are perpendicularly connected to the connecting pipes 530 and are spaced apart along the extension direction of the aeration pipes 520. The main aeration pipe 510 supplies oxygen, which is then transported to the multiple connecting pipes 530 and discharged into the aerobic tank 200 through the aeration pipes 520. This arrangement ensures that oxygen is fully injected into the wastewater to be treated, facilitating thorough mixing and improving the wastewater oxidation and decomposition rate.

[0073] In one possible implementation, such as Figure 7 As shown, both the anaerobic tank 100 and the aerobic tank 200 are covered with transparent covers 600. It is understood that the transparent covers 600 are sealed to the anaerobic tank 100 and to the aerobic tank 200 via fasteners, preventing rainwater and debris from entering the interior of the anaerobic tank 100 and the aerobic tank 200 and causing wastewater overflow, thus ensuring the stable operation of the wastewater treatment device. Furthermore, the transparent covers 600 can isolate the tanks from external air and moisture, reducing corrosion of the anaerobic tank 100 and the aerobic tank 200.

[0074] The transparent cover plate 600 can be made of fiberglass, which is corrosion resistant and prevents corrosive droplets generated by the reaction of wastewater in the anaerobic tank 100 and the aerobic tank 200 from splashing onto the transparent cover plate 600 and causing damage.

[0075] In other embodiments, the transparent cover 600 on the anaerobic tank 100 may include fiberglass and an insulation layer. Two layers of fiberglass are provided, with the insulation layer sandwiched between the two layers of fiberglass to prevent temperature loss within the anaerobic tank 100 and ensure that the anaerobic tank 100 is in a constant temperature environment so that the anaerobic bacteria within the anaerobic tank 100 are in an active state and can effectively decompose the organic matter in the wastewater to be treated.

[0076] Secondly, embodiments of this application provide a beer production line, such as... Figure 8 As shown, the apparatus includes a mashing pot 720, a settling tank 730, and a beer wastewater treatment device according to the first aspect. Both the mashing pot 720 and the settling tank 730 have wastewater outlets 740, and both wastewater outlets 740 are connected to the anaerobic tank 100 of the beer wastewater treatment device.

[0077] Understandably, in combination Figure 8 As shown, during the beer production process, the raw malt for beer can be fed into a grinder for crushing, and the crushed malt can be fed into a mashing kettle 720 for heating and hydrolysis to obtain crude wort. The crude wort can be fed into a filter tank to filter out undigested impurities, and then fed into a wort boiling kettle to evaporate excess water from the crude wort, obtaining concentrated wort of a specified concentration. The concentrated wort can be fed into a fermentation tank 900 for fermentation to obtain beer. Wastewater is inevitably generated during the entire production process. Therefore, both the mashing kettle 720 and the settling tank 730 can have wastewater outlets 740. Both wastewater outlets 740 are connected to the anaerobic tank 100 of the beer wastewater treatment device, which purifies the generated wastewater and prevents direct discharge into the environment.

[0078] Of course, in other embodiments, it is not limited to connecting the wastewater outlets 740 of the mashing pot 720 and the sedimentation tank 730 to the anaerobic pool 100 of the beer wastewater treatment device. Devices such as wort boiling pots and filter tanks used in the beer production process can also have wastewater outlets 740, which are also connected to the anaerobic pool 100 of the beer wastewater treatment device in order to treat the wastewater generated in the beer production process.

[0079] In one possible implementation, reference is made to Figure 8 As shown, it also includes a water storage tank 710 and a heat exchanger 800.

[0080] The heat exchanger 800 is connected to the outlet end of the settling tank 730. The heat exchanger 800 is used to cool the hot wort generated in the settling tank 730.

[0081] The outlet end of the saccharification pot 720 is connected to the sedimentation tank 730. Both the saccharification pot 720 and the sedimentation tank 730 are connected to the outlet end of the water storage tank 710. The water storage tank 710 is used to supply hot water to the saccharification pot 720 and the sedimentation tank 730. The inlet end of the water storage tank 710 is connected to the outlet end of the heat exchanger 800.

[0082] Understandably, in combination Figure 8 As shown, the water storage tank 710 has a heating device to heat the water in the water storage tank 710 to form hot water. The water storage tank 710 is connected to the saccharification pot 720 and the sedimentation tank 730 through water supply pipes, so that hot water can be delivered to the saccharification pot 720 and the sedimentation tank 730 respectively for their use.

[0083] The saccharification pot 720 and the sedimentation tank 730 are connected in sequence, and the outlet end of the sedimentation tank 730 is connected to the inlet end of the heat exchanger 800. Cold water can be introduced into the heat exchanger 800. The outlet end of the sedimentation tank 730 outputs concentrated hot wort to exchange heat with the cold water in the heat exchanger 800, thereby reducing the temperature of the concentrated hot wort for subsequent fermentation processing.

[0084] The outlet of heat exchanger 800 can be connected to the inlet of water storage tank 710. Understandably, after heat exchange, the temperature of the cold water in heat exchanger 800 rises, making it insufficient to continue exchanging heat with the concentrated hot wort. Directly discharging this heated cold water to the outside would waste water. This new design allows the heated cold water to be transported to water storage tank 710, utilizing waste heat from the beer production process, reducing the preheating time in water storage tank 710, and preventing water waste.

This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and alterations may be made without departing from its scope.
