Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a combined liquor wastewater treatment system based on microwave technology. Background Technology

[0002] The raw materials for baijiu (Chinese liquor) are mainly wheat, corn, and sorghum. Wastewater generated during the brewing process includes distillation bottom pot water, koji box cleaning water, koji printing wastewater, baijiu lees waste liquid, fermentation tank leachate, grain soaking water, distillation cooling water, and equipment cleaning wastewater. This type of wastewater mainly consists of amino acids, low-carbon alcohols (such as ethanol and pentanol), and fatty acids, and is classified as high-concentration organic wastewater. It is characterized by high chemical oxygen demand (COD) concentration, high suspended solids (SS) content, strong biodegradability, and complex composition.

[0003] Currently, microwave technology is commonly used to treat liquor wastewater. The microwave magnetic field can effectively reduce the strength of chemical bonds between organic molecules, thereby reducing the association between organic molecules. This provides a new solution for the treatment of liquor wastewater. In order to improve the removal efficiency of molecular organic matter in wastewater, hydrogen peroxide needs to be added to the wastewater. Hydrogen peroxide decomposes to generate strong oxidizing hydroxyl radicals, which increases the probability of contact and collision between hydroxyl radicals and organic molecules in wastewater, thereby improving the removal efficiency of large molecular organic matter in wastewater. However, in the current treatment of liquor wastewater, hydrogen peroxide cannot be effectively and fully mixed with the wastewater, resulting in a reduction in the removal efficiency of molecular organic matter in the wastewater.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model. Example

[0036] like Figures 1 to 8As shown, this utility model includes an adjustment device and a microwave decomposition device. The adjustment device includes an adjustment box 101 and a drive mechanism 102. The rotation shaft 105 of the drive mechanism 102 extends into the adjustment box 101. An expansion member 104 and a first stirring plate 109 are provided on the rotation shaft 105. A first connecting member is provided on the expansion member 104. A plurality of first air holes 127 and a second connecting member communicating with the first air holes 127 are provided on the first stirring plate 109. The first stirring plate 109 can move axially along the rotation shaft 105 to connect the first connecting member and the second connecting member. The microwave decomposition device includes a decomposition box 201 and a microwave source 202 disposed on the decomposition box 201. The adjustment box 101 and the decomposition box 201 are connected by a conduit 203.

[0037] This technical solution treats wastewater generated during the production of baijiu (Chinese liquor) using a regulating device and a microwave decomposition device. The wastewater is transported to a regulating tank 101, and then an appropriate amount of hydrogen peroxide is added. A drive mechanism 102, a motor, drives a rotating shaft 105 to rotate within the regulating tank 101. A first stirring plate 109 acts on the wastewater and hydrogen peroxide in the regulating tank 101, ensuring thorough mixing. Simultaneously, this technology… To improve the thorough mixing of hydrogen peroxide and wastewater, the rotating shaft 105 is equipped with an expansion member 104, and the first stirring plate 109 can move on the rotating shaft 105. Thus, while the rotating shaft 105 drives the first stirring plate 109 to rotate, the first stirring plate 109 can also move vertically within the regulating tank 101, changing its position. This allows the first stirring plate 109 to act on wastewater at different depths, improving the mixing strength of wastewater and hydrogen peroxide within the regulating tank 101.

[0038] Meanwhile, when the first stirring plate 109 moves to the expansion member 104, the first connecting member and the second connecting member are connected. Thus, when the first stirring plate 109 continues to move towards the expansion member 104, it will squeeze the expansion member 104, thereby transferring the medium in the expansion member 104 to the first air hole 127 on the first stirring plate 109 through the first connecting member and the second connecting member. Finally, it is sprayed out from the first air hole 127 and acts on the wastewater in the regulating tank 101, achieving the effect of bubbling the wastewater in the regulating tank 101, and further improving the full mixing between the wastewater and hydrogen peroxide.

[0039] After thorough mixing of wastewater and hydrogen peroxide in the equalization tank, the wastewater in the equalization tank 101 is transported to the decomposition tank 201 using the lift pump 9 on the conduit 203. During the transport of the wastewater in the conduit 203, the hydrogen peroxide in the conduit 203 within the decomposition tank 201 decomposes under the action of the microwave source 202, generating strong oxidizing hydroxyl radicals. This increases the probability of hydroxyl radicals colliding with organic molecules in the wastewater, thereby improving the removal efficiency of large organic molecules in the wastewater. In addition, the non-thermal effect of microwaves can weaken the chemical bonds of reactant molecules, lower the activation energy of the reaction, increase the reaction rate, and stimulate the decomposition of organic matter, so that the wastewater can initially reduce COD and improve biodegradability in the subsequent sedimentation tank.

[0040] In another embodiment, the conduit 203 located in the decomposition box 201 is configured in a serpentine or spiral shape to increase the time that the microwave source 202 interacts with the wastewater in the conduit 203.

[0041] The rotating shaft 105 is provided with a first through hole 123, and the side walls of the rotating shaft 105 are provided with strip-shaped openings 124, which are connected to the first through hole 123; the first stirring plate 109 is located in the strip-shaped openings 124, and the bottom of the first stirring plate 109 is provided with a guide block 128, which is located in the first through hole 123.

[0042] In this embodiment, in order to ensure that the first stirring plate 109 can move on the rotating shaft 105 and change the height of the first stirring plate 109 to meet the stirring of sewage at different depths, a first through hole 123 and a strip opening 124 are provided on the rotating shaft 105. The width of the strip opening 124 is smaller than the inner diameter of the first through hole 123. This ensures that the guide block 128 located in the first through hole 123 does not fall off from the strip openings 124 on both sides. It can only move vertically in the first through hole 123. When the guide block 128 moves in the first through hole 123, the first stirring plate 109 will move in the strip opening 124.

[0043] The expansion member 104 includes an airbag 116 with an annular structure. A fixing plate is provided on the rotating shaft 105. The airbag 116 is sleeved on the rotating shaft 105, and the top of the airbag 116 is connected to the bottom of the fixing plate.

[0044] In this embodiment, the expansion member 104 is an airbag 116, which is made of nitrile rubber, a corrosion-resistant material. Several springs are provided inside the airbag 116, and the springs are distributed along the axial direction of the rotation shaft 105. The springs are used to ensure that the airbag 116 is in an inflated state.

[0045] The first connector includes a telescopic tube 117 and a connector 118, both located within the first through hole 123. The telescopic tube 117 communicates with the airbag 116, and the connector 118 is connected to the bottom of the telescopic tube 117. The connector 118 has a cavity communicating with the telescopic tube 117, and the bottom of the connector 118 has an inlet communicating with the cavity. The cavity contains a first elastic element and a sealing plate 119, the first elastic element pushing the sealing plate 119 to seal the inlet. The second connector includes a connecting post 120 with an outer diameter matching the inner diameter of the inlet. The connecting post 120 is located within the first through hole and connected to the top of the first stirring plate 109. The side wall of the connecting post 120 has a first channel communicating with the first air hole 127.

[0046] To achieve communication between the first and second connecting parts, the first connecting part includes a telescopic tube 117 and a connector 118. Initially, the sealing plate 119 inside the connector 118 seals the inlet under the action of the first elastic element, and the telescopic tube 117 and the airbag 116 are in a closed state. When the first stirring plate 109 moves towards the airbag 116, the connecting post 120 on the first stirring plate 109 extends into the inlet and pushes the sealing plate 119 back. When the first channel on the side wall of column 120 extends into the cavity, the telescopic tube 117 will be connected to the first channel. Therefore, when the first stirring plate 109 squeezes the airbag 116, the fluid medium in the airbag 116 will pass through the telescopic tube 117, the cavity, the first channel and the first air hole 127 in sequence, and finally the fluid medium in the airbag 116 will be applied to the wastewater in the regulating tank 101 through the first air hole 127 to achieve the purpose of bubbling the wastewater, thereby improving the mixing strength between hydrogen peroxide and sewage.

[0047] The regulating box 101 is also provided with an inlet pipe 103. The inlet pipe 103 extends into the side wall of the regulating box 101 and is also provided with a horizontal pipe. The end of the horizontal pipe is provided with a connecting sleeve 130. The rotating shaft 105 is also provided with an annular groove 125. The rotating shaft 105 is also provided with a second channel 126. One end of the second channel 126 is connected to the annular groove 125 and the other end is connected to the telescopic pipe 117. The connecting sleeve 130 is fitted on the annular groove 125 of the rotating shaft 105 and the horizontal pipe is connected to the annular groove.

[0048] In this embodiment, the inlet pipe 103 is connected to a tank containing hydrogen peroxide. Hydrogen peroxide can be delivered into the horizontal pipe through the inlet pipe 103. The hydrogen peroxide then enters the second channel 126 through the annular groove 125 and is finally delivered into the airbag 116. The hydrogen peroxide is temporarily stored in the airbag 116. When the first stirring plate 109 squeezes the airbag 116, the hydrogen peroxide stored in the airbag 116 can be sprayed out from the first air hole 127 through the first connector and the second connector, acting on the wastewater so that the wastewater and hydrogen peroxide can be fully mixed.

[0049] Because the wastewater generated during the production of baijiu (Chinese liquor) may fluctuate drastically due to factors such as production batches and cleaning cycles, a regulating tank 101 is used to mix and buffer the wastewater to make its concentration more uniform, thus avoiding impact on the subsequent microwave decomposition device. Therefore, when wastewater of different concentrations is discharged into the regulating tank 101 simultaneously, the first stirring plate 109 is used to stir the wastewater of different concentrations to make it more uniform before adding hydrogen peroxide to the regulating tank 101. Therefore, in this embodiment, the added hydrogen peroxide is stored in the airbag 116. When the rotating shaft 105 drives the first stirring plate 109 to rotate, it first stirs the wastewater of different concentrations discharged into the regulating tank 101 to make its concentration tend to be uniform. During the stirring process, the first stirring plate 109 moves towards the air bag 116 and eventually connects the first connecting member with the second connecting member. In this way, when the first stirring plate 109 squeezes the air bag 116, the hydrogen peroxide stored in the air bag 116 will act on the wastewater through the first air hole 127 on the first stirring plate 109, so that the hydrogen peroxide and the uniformly mixed wastewater can be fully mixed again.

[0050] The bottom of the regulating box 101 is also equipped with an air pump 108, and the rotating shaft 105 is also equipped with a second through hole 129 communicating with the first through hole 123. The inner diameter of the second through hole 129 is larger than that of the first through hole 123. The air pump 108 is also connected to the second through hole 129. The second through hole 129 is equipped with a movable block 112 and a push rod 110. The outer diameter of the movable block 112 is the same as the inner diameter of the second through hole 129, and the push rod 110 is used to push the guide block 128 to move within the first through hole 123.

[0051] In this embodiment, in order to ensure that the first stirring plate 109 can move smoothly in the vertical direction in the regulating box 101 and change the position of the first stirring plate 109, an air pump 108 is also provided. When the air pump 108 is working, it can deliver pressurized gas into the second through hole 129 of the rotating shaft 105. The pressurized gas entering the second through hole 129 pushes the movable block 112 to move upward in the second through hole 129, thereby causing the push rod 110 to push the guide block 128 to move upward in the first through hole 123, thus realizing the adjustment of the position of the first stirring plate 109.

[0052] In another embodiment, the inner bottom of the adjustment box 101 is provided with a bearing that matches the rotating shaft 105, thus ensuring that the lower end of the rotating shaft 105 can be rotatably connected to the bottom of the adjustment box 101.

[0053] The rotating shaft 105 is also provided with a second stirring plate 107 on its side wall, which is located below the first stirring plate 109. The surface of the second stirring plate 107 is provided with a plurality of second air holes. The rotating shaft 105 is also provided with a third channel 114, one end of which is connected to the second through hole 129 and the other end is connected to the second air hole. The rotating shaft 105 is also provided with a fourth channel, which passes through the third channel 114. The fourth channel is provided with a sealing block 115 for sealing the fourth channel.

[0054] In this embodiment, in order to further improve the stirring force of the sewage, a second stirring plate 107 is also provided on the rotating shaft 105. The second stirring plate 107 is close to the inner bottom of the regulating tank 101, and the wastewater in the lower part of the regulating tank 101 can be stirred by the provided second stirring plate 107.

[0055] The inner wall of the second through hole 129 is also provided with a first blind hole. The bottom of the first blind hole is connected to the fourth channel. The first blind hole is provided with a second elastic element and a first unlocking block 121. The outer diameter of the first unlocking block 121 is the same as the inner diameter of the first blind hole. The sealing block 115 is also provided with a third through hole. The inner wall of the first blind hole is provided with a locking groove. The first unlocking block 121 is provided with an installation groove. The installation groove is provided with a third elastic element and a locking block 122.

[0056] The inner wall of the second through hole 129 is also provided with a second blind hole. The second blind hole is located below the first blind hole. The second blind hole is connected to the locking groove. The second blind hole is provided with a fourth elastic element and a second unlocking block 111. The outer diameter of the second unlocking block 111 is the same as the inner diameter of the second blind hole.

[0057] In this embodiment, to further enhance the stirring force of the second stirring plate 107 on the waste, several second air holes are also provided on the second stirring plate 107. Simultaneously, a third channel 114 and a fourth channel are provided within the rotating shaft 105. The fourth channel and the third channel 114 are perpendicularly connected. A fifth elastic element and a sealing block 115 are provided within the fourth channel. The inner diameter of the fourth channel is larger than the inner diameter of the third channel 114, ensuring that the sealing block 115 can seal the third channel 114. Initially, the fifth elastic element causes the third through hole on the sealing block 115 to be within the fourth channel. When the pressurized gas generated by the air pump 108 enters the second through hole 129, it pushes the movable block 112 upwards within the second through hole 129. When the movable block 112 moves to the first unlocking block 121, the... The side wall of the movable block 112 will push the first unlocking block 121 back into the first blind hole. When the first unlocking block 121 retracts, it will squeeze the air in the first blind hole, causing a portion of the air in the first blind hole to enter the fourth channel. This will push the sealing block 115 in the fourth channel toward the fifth elastic element, eventually causing the third through hole on the sealing block 115 to move into the third channel 114. Under the action of the third through hole, the third channel 114 will be opened. At this time, the operation of the air pump 108 will be stopped, and the movable block 112 will retract downwards. During the retraction process, the air in the second through hole 129 will be squeezed into the third channel 114. The air that enters the third channel 114 will eventually be discharged through the second air hole on the second stirring plate 107, thus achieving the purpose of bubbling the wastewater in the lower layer of the regulating tank 101.

[0058] A sixth elastic element 113 is also provided in the second through hole 129 of the rotating shaft 105. The sixth elastic element 113 is connected to the movable block. The bottom of the regulating box 101 is also provided with an air inlet. The air pump 108 is connected to the second through hole 129 through the air inlet. A one-way valve is provided in the second through hole 129. The one-way valve is used to ensure that the gas generated by the air pump 108 can enter the second through hole 129, while the air in the second through hole 129 cannot flow back through the one-way valve.

[0059] In this way, the sixth elastic element 113 can be used to pull the movable block 112 back quickly in the second through hole 129, thereby squeezing the remaining air in the second through hole 129 to the second air hole of the second stirring plate 107, so as to achieve the purpose of bubbling the wastewater in the regulating tank 101.

[0060] To prevent the first unlocking block 121 from retracting from the first blind hole during the downward retraction of the movable block 112, thus creating negative pressure in the first blind hole and causing the third through hole on the sealing block 115 to be moved out of the third channel 114, the first unlocking block 121 is also provided with an upper mounting groove. The mounting groove contains a third elastic element and a locking block 122. When the movable block 112 pushes the end of the first unlocking block 121 completely back into the first blind hole, the locking block 122, under the action of the third elastic element, is inserted into the locking groove, thereby fixing the first unlocking block 121 in the first blind hole. When the movable block 112 retracts to the second unlocking block 111, the side wall of the movable block 112 pushes the second unlocking block... 111 retracts into the second blind hole. During the retraction process, the second unlocking block 111 compresses the air in the second blind hole, causing some of the air in the second blind hole to enter the unlocking groove, pushing the locking block 122 out of the unlocking groove, removing the restriction on the first unlocking block 121, and thus allowing the first unlocking block 121 to re-enter the second through hole 129. During the movement of the first unlocking block 121, the negative pressure generated in the first blind hole will cause the third through hole on the sealing block 115 to move back into the fourth channel, disconnecting the third channel 114, so that when the air pump 108 delivers pressurized gas to the second through hole 129, the pressurized gas entering the second through hole 129 will not leak through the third channel 114.

[0061] In another embodiment, the first unlocking block 121 and the second unlocking block 111 are both provided with inclined plates at the ends of the second through hole 129, so as to ensure that the movable block 112 can smoothly push the first unlocking block 121 and the second unlocking block 111 to move radially along the rotation axis 105 when moving in the second through hole 129.

[0062] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
