Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically to a wastewater deodorization device. Background Technology

[0002] Wastewater treatment often produces unpleasant odors, which not only affect the quality of life of surrounding residents but may also cause secondary pollution to the environment and ecosystem. Deodorization is necessary. Traditional wastewater treatment equipment requires a large amount of electrical equipment such as water pumps and drive motors to operate, which consumes a lot of energy.

[0003] In current wastewater deodorization systems, the direct addition of activated carbon to wastewater often results in uneven dispersion due to the attraction between activated carbon particles and the flow characteristics of the wastewater. This uneven distribution limits the contact area between the activated carbon and odorous components in the wastewater, preventing a large amount of activated carbon from fully utilizing its adsorption capacity and significantly reducing the overall deodorization effect. Furthermore, existing wastewater deodorization systems often rely on additional mechanical equipment (such as agitators) for forced mixing to maximize the dispersion and mixing efficiency of activated carbon. These devices consume a large amount of electricity during operation, increasing the operating costs of wastewater treatment plants and exacerbating energy waste and carbon emissions. Consequently, activated carbon exhibits poor dispersion in direct wastewater discharge, resulting in low deodorization efficiency and high energy consumption during operation. Therefore, a wastewater deodorization device is proposed. Summary of the Invention

[0004] To address the problems in existing technologies, this invention provides a wastewater deodorization device, offering a pulse-type deodorization system based on activated carbon for wastewater treatment. This system uses pulse-type spraying of activated carbon mixture into the wastewater deodorization treatment tank, ensuring more thorough mixing of the activated carbon and achieving deodorization. By converting the air energy generated by the air pump into pulse-type air pressure and mechanical rotational force, it achieves multiple uses and efficient conversion of energy, reducing overall energy consumption. Simultaneously, it improves the synchronization and coordination between various components. The pulse-type spraying also allows the activated carbon to be better dispersed in the wastewater, enhancing the deodorization effect.

[0005] The technical solution adopted by the present invention to solve its technical problem is a sewage deodorization device, including a base and a powder section. The powder section is disposed at one end of the top of the base. An air pump and a water pump are respectively installed on both sides of the top of the base. A mixing component is installed at the bottom of the base. A transducer is provided on the top of the base for providing discharge driving force for the powder section and pulse pressurization for the mixing component. The mixing component is connected to the powder section and the water pump respectively.

[0006] By adopting the above technical solution, a pulse-type deodorization device based on activated carbon is provided for wastewater treatment through a component consisting of a powder section, a mixing assembly, a transducer, an air pump, and a water pump. The air pump provides pneumatic driving force to the transducer, which converts the air pressure from the air pump into intermittent pulse-type pneumatic power and sends this power to the mixing assembly. At the same time, the transducer converts the air energy supplied by the air pump into mechanical rotational force, which drives the powder section to discharge activated carbon powder to the mixing assembly and drives the water pump. The system operates by supplying water and activated carbon powder to the mixing components via a driven water pump and powder section. This, combined with pulse-type pneumatic pressurization, enables the activated carbon mixture to be pulsed and sprayed into the wastewater deodorization treatment tank. This ensures that the activated carbon is more thoroughly mixed into the wastewater deodorization treatment tank, thus achieving the deodorization operation. The air energy of the air pump is converted into pulse-type pneumatic drive and mechanical transmission power through a transducer, thereby providing kinetic energy through the pulse-type pneumatic drive and mechanical transmission, improving energy utilization efficiency, and enhancing the synchronization of the operation between various components.

[0007] Specifically, the transducer includes a circular box and an irregularly shaped impeller. The irregularly shaped impeller is disposed inside the circular box. An air collection box is disposed on the top of the circular box. An air inlet is disposed on one side of the air collection box. The exhaust end of the air pump is connected to the air inlet. A first exhaust nozzle and a second exhaust nozzle for driving the irregularly shaped impeller to rotate are respectively obliquely connected to both sides of the bottom of the air collection box. The exhaust ends of the first exhaust nozzle and the second exhaust nozzle are connected to the top of the circular box. An exhaust nozzle for pressurizing the mixing component is connected to the bottom of the circular box.

[0008] The round box is located on one side of the powder section. An end cap is installed on one side of the round box, and a support is provided at the bottom of the round box. The two ends of the support are connected to the base by bolts.

[0009] By adopting the above technical solution, a high-pressure air is provided to the air collection box by an air pump, so that the first exhaust nozzle and the second exhaust nozzle, which are set at the bottom of the air collection box at an angle, discharge air into the circular box. The air is sprayed onto the irregular impeller, which drives the irregular impeller to rotate.

[0010] Specifically, the irregular impeller includes a bushing and wedge-shaped blades connected at equal distances along the outer circumference of the bushing. The wedge-shaped blades are hollow, and the curvature of the end of the wedge-shaped blades is consistent with the curvature of the inner wall of the circular box. The top of the wedge-shaped blades is provided with a notch for improving the air thrust friction. An air storage cavity is formed between the wedge-shaped blades.

[0011] By adopting the above technical solution, the first exhaust nozzle and the second exhaust nozzle can alternately spray air onto the irregular impeller. After one set of exhaust nozzles, either the first or the second exhaust nozzle, is blocked by the wedge-shaped blade, the other set of nozzles will take over and exhaust air onto the wedge-shaped blade at its bottom. This allows for alternating air supply between the first and second exhaust nozzles, ensuring the rotation of the irregular impeller.

[0012] In this structure, the wedge-shaped blade block is only used as a driven structure and cannot store air. However, the air storage chamber can store the high-pressure air discharged from the first or second exhaust nozzle. After the high-pressure air reaches the exhaust nozzle, it can be depressurized through the exhaust nozzle. The alternating passage of the wedge-shaped blade block and the air storage chamber will cause the air discharged from the exhaust nozzle to form a pulse airflow, thereby providing pulse pneumatic boosting for the mixing component.

[0013] Specifically, both ends of the bushing are rotatably connected to the round box via bearings. The center of the bushing has a shaft insertion hole, and an output shaft is installed in the shaft insertion hole via a key pin. One end of the output shaft passes through the round box and is installed with a first synchronous pulley via a key pin.

[0014] By adopting the above technical solution, the rotation of the wedge-shaped blade will drive the first synchronous wheel to rotate, thus converting air energy into mechanical rotational force.

[0015] Specifically, the powder section includes a feeding seat and a hopper-shaped cylinder for storing activated carbon powder. The feeding seat is installed on the top of the base, and the hopper-shaped cylinder is fixed to the top of the feeding seat by a flange. The discharge end of the hopper-shaped cylinder is connected to the feed end of the feeding seat. A conveying cylinder is provided at the discharge end of the feeding seat. An auger is provided inside the conveying cylinder and the feeding seat. The rotating shaft of the auger passes through the feeding seat and is equipped with a second synchronous pulley by a key pin. The second synchronous pulley is connected to the first synchronous pulley by a synchronous belt.

[0016] The discharge end of the conveying cylinder is connected to a powder feeding pipe.

[0017] By adopting the above technical solution, the rotational power is transmitted to the second synchronous wheel through the first synchronous wheel, causing the auger to rotate. Thus, the auger can push the activated carbon powder in the bucket-shaped cylinder to the powder feeding pipe, thereby realizing synchronous feeding of the mixing components.

[0018] Specifically, the mixing assembly includes a venturi tube, a tee, and a discharge pipe for connection to the sewage tank. The discharge end of the venturi tube is connected to the discharge pipe. A gas-liquid interface is provided at the end of the venturi tube away from the discharge pipe. A powder interface is connected to the top of the throat of the venturi tube. The feed end of the powder interface is connected to the discharge end of the powder feed pipe.

[0019] By adopting the above technical solution, the water supplied and discharged by the pump is combined with pulsed air pressure at the three-way valve, which accelerates the water flow into the Venturi tube. Through the Venturi effect, a negative pressure is formed at the throat of the Venturi tube. Activated carbon powder is drawn into the powder supply pipe through the powder interface and pulsedly discharged into the wastewater deodorization tank through the discharge pipe. The pulsed spraying allows the activated carbon to be better dispersed in the wastewater, improving the deodorization effect. Furthermore, the pulsed pressurization prevents clogging in the mixing components, ensuring smooth operation of the water, air, and powder mixing and spraying process.

[0020] Specifically, the tee includes a water inlet pipe, an air inlet pipe, and a gas-liquid manifold. The water inlet pipe and the air inlet pipe are respectively connected to both sides of the gas-liquid manifold, and the discharge end of the gas-liquid manifold is connected to the gas-liquid interface.

[0021] Specifically, the water pump's drain end is connected to a drain pipe, the water pump's inlet end is connected to an inlet pipe, the inlet end of the inlet pipe is connected to the drain end of the drain pipe, and the air inlet end of the air inlet pipe is connected to the exhaust end of the exhaust nozzle.

[0022] One-way valves are installed on the gas-liquid manifold, water inlet pipe, and air inlet pipe.

[0023] By adopting the above technical solution, the water inlet of the water pump can be connected to the water supply end of the water treatment site through the water inlet pipe, and the water discharged by the water pump can be sent to the water inlet pipe of the mixing component through the drain pipe.

[0024] Specifically, a third synchronous pulley is coaxially mounted on the end of the second synchronous pulley away from the feed seat, and a fourth synchronous pulley is mounted on the end of the impeller input shaft of the water pump, the fourth synchronous pulley being located on the outside of the water pump casing;

[0025] The third and fourth synchronous pulleys are connected by a synchronous belt.

[0026] By adopting the above technical solution, the water pump can operate based on the mechanical rotational force converted by the transducer component through the cooperation of the third and fourth synchronous pulleys.

[0027] The beneficial effects of this invention are as follows: The assembly, consisting of a powder section, a mixing component, a transducer, an air pump, and a water pump, provides a pulse-type deodorization device based on activated carbon for wastewater treatment. The air pump provides pneumatic driving force to the transducer, which converts the air pressure from the air pump into intermittent pulse-type pneumatic power, which is then sent to the mixing component. Simultaneously, the transducer converts the air energy supplied by the air pump into mechanical rotational force. This mechanical rotational force drives the powder section to discharge activated carbon powder to the mixing component and drives the water pump. The driven water pump and powder section supply water and activated carbon powder to the mixing component, which, combined with the pulse-type pneumatic power... Dynamic pressurization enables pulsed spraying of activated carbon mixture into the wastewater deodorization treatment tank, allowing the activated carbon to be more thoroughly mixed into the tank and achieving deodorization. By converting the air energy generated by the air pump into pulsed air pressure and mechanical rotational force, energy is utilized and converted efficiently, reducing overall energy consumption. Simultaneously, the synchronization and coordination between components are improved. Pulsed spraying allows the activated carbon to be better dispersed in the wastewater, enhancing the deodorization effect. The compact structure facilitates installation and maintenance, solving the problems of poor dispersion of activated carbon in direct wastewater discharge, resulting in low deodorization efficiency and high energy consumption during operation.

Detailed Implementation

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] To convert air energy into pulsed pneumatic drive and mechanical transmission power, thereby enabling the pulsed pneumatic drive and mechanical transmission to work together to provide kinetic energy, energy utilization efficiency is improved, and the synchronization of the operation between various components is also enhanced. Figure 1-7As shown, the wastewater deodorization device of the present invention includes a base 6 and a powder section 1. The powder section 1 is disposed at one end of the top of the base 6. An air pump 2 and a water pump 4 are respectively installed on both sides of the top of the base 6. A mixing assembly 5 is installed at the bottom of the base 6. A transducer 3 is disposed on the top of the base 6 for providing discharge driving force for the powder section 1 and pulse pressurization for the mixing assembly 5. The mixing assembly 5 is connected to the powder section 1 and the water pump 4 respectively.

[0039] In operation, the powder section 1, mixing assembly 5, transducer 3, air pump 2, and water pump 4 provide a pulse-type deodorization device based on activated carbon for wastewater treatment. Air pump 2 provides pneumatic driving force to transducer 3, which converts the air pressure from air pump 2 into intermittent pulse-type pneumatic power, which is then sent to mixing assembly 5. Simultaneously, transducer 3 converts the air energy supplied by air pump 2 into mechanical rotational force, which drives powder section 1 to discharge activated carbon powder to mixing assembly 5 and drives water pump 4. The driven water pump 4 and powder section 1 supply water and activated carbon powder to the mixing component 5. With the help of pulsed pneumatic power, the activated carbon mixture is pulsedly sprayed into the sewage deodorization treatment tank, so that the activated carbon is more thoroughly mixed into the sewage deodorization treatment tank, thus achieving the deodorization operation of sewage. The air energy of the air pump 2 is converted into pulsed pneumatic drive and mechanical transmission through the energy transducer 3, so that the pulsed pneumatic drive and mechanical transmission work together to provide kinetic energy, improving energy utilization efficiency and improving the synchronization of the operation between the components.

[0040] Compressed air is generated by air pump 2 and sent into air collection box 33 through air inlet 331. The compressed air is sprayed onto the shaped impeller 32 through first exhaust port 332 and second exhaust port 333, driving it to rotate. The rotation of the shaped impeller 32 is transmitted to the first synchronous pulley 35 through output shaft 36, and drives the second synchronous pulley 15 to rotate. Screw 14 can push the activated carbon powder in bucket cylinder 11 to powder feeding pipe 131.

[0041] In order for the transducer to convert high-pressure air into pulsed pneumatic drive and mechanical transmission power, for example, such as Figure 1-4 As shown, the present invention also includes the following: the transducer 3 includes a circular box 31 and an irregularly shaped impeller 32. The irregularly shaped impeller 32 is disposed inside the circular box 31. An air collection box 33 is disposed on the top of the circular box 31. An air inlet 331 is disposed on one side of the air collection box 33. The exhaust end of the air pump 2 is connected to the air inlet 331. A first exhaust nozzle 332 and a second exhaust nozzle 333 for driving the irregularly shaped impeller 32 to rotate are respectively inclinedly connected to the bottom two sides of the air collection box 33. The exhaust ends of the first exhaust nozzle 332 and the second exhaust nozzle 333 are connected to the top of the circular box 31. An exhaust nozzle 34 for pressurizing the mixing component 5 is connected to the bottom of the circular box 31.

[0042] The round box 31 is located on one side of the powder section 1. An end cap 311 is installed on one side of the round box 31. A support 312 is provided at the bottom of the round box 31. The two ends of the support 312 are connected to the base 6 by bolts.

[0043] In use, the air pump 2 delivers high-pressure air to the air collection box 33, causing the first exhaust nozzle 332 and the second exhaust nozzle 333, which are inclined at the bottom of the air collection box 33, to discharge air into the circular box 31. The air is then sprayed onto the irregular impeller 32, which drives the irregular impeller 32 to rotate.

[0044] To provide pulsed pneumatic boosting for the mixing assembly, for example, such as Figure 1 , 6 As shown, the present invention also includes the irregular impeller 32 comprising a bushing 321 and wedge-shaped blade blocks 323 connected at equal distances along the outer periphery of the bushing 321. The wedge-shaped blade blocks 323 are hollow structures, and the curvature of the end of the wedge-shaped blade blocks 323 is consistent with the curvature of the inner wall of the circular box 31. The top of the wedge-shaped blade blocks 323 is provided with a notch 325 for improving the air thrust friction. An air storage cavity 324 is formed between the wedge-shaped blade blocks 323.

[0045] In use, the air pump 2 pressurizes the exhaust in the air box 33, and the first exhaust nozzle 332 and the second exhaust nozzle 333 can alternately spray air onto the irregular impeller 32. After one set of exhaust nozzles, the first exhaust nozzle 332 or the second exhaust nozzle 333, is blocked by the wedge-shaped blade block 323, the other set of nozzles will take over and exhaust air onto the wedge-shaped blade block 323 at its lower bottom, so that the first exhaust nozzle 332 and the second exhaust nozzle 333 can alternately supply air to each other to ensure the rotation of the irregular impeller 32.

[0046] Similarly, the wedge-shaped blade block 323 is only a pushed structure and cannot store air, while the air storage chamber 324 can store the high-pressure air discharged by the first exhaust nozzle 332 or the second exhaust nozzle 333. After the high-pressure air reaches the exhaust nozzle 34, it can be depressurized through the exhaust nozzle 34. The alternating passage of the wedge-shaped blade block 323 and the air storage chamber 324 will cause the air discharged from the exhaust nozzle 34 to form a pulse airflow, thereby providing pulse pneumatic boosting for the mixing component 5.

[0047] In order to convert air energy into mechanical rotational force, for example, such as Figure 1-4 As shown, the present invention also includes that the two ends of the bushing 321 are rotatably connected to the round box 31 by bearings respectively, and the center of the bushing 321 is provided with a shaft insertion hole 322. An output shaft 36 is installed in the shaft insertion hole 322 by a key pin. One end of the output shaft 36 passes through the round box 31 and is installed with a first synchronous pulley 35 by a key pin.

[0048] In use, the wedge-shaped blade block 323 is rotated by the air jet from the first exhaust nozzle 332 or the second exhaust nozzle 333. The output shaft 36 in the wedge-shaped blade block 323 drives the first synchronous pulley 35 to rotate based on the rotational force, so that the air energy is converted into mechanical rotational force.

[0049] To achieve synchronous feeding of the mixing components, for example, such as Figure 1-7 As shown, the present invention further includes the following: the powder section 1 includes a feeding seat 12 and a bucket-shaped cylinder 11 for storing activated carbon powder. The feeding seat 12 is installed on the top of the base 6. The bucket-shaped cylinder 11 is fixed to the top of the feeding seat 12 by a flange, and the discharge end of the bucket-shaped cylinder 11 is connected to the feed end of the feeding seat 12. The discharge end of the feeding seat 12 is provided with a conveying cylinder 13. An auger 14 is provided inside the conveying cylinder 13 and the feeding seat 12. The rotating shaft of the auger 14 passes through the feeding seat 12 and is mounted with a second synchronous pulley 15 by a key pin. The second synchronous pulley 15 is connected to the first synchronous pulley 35 by a synchronous belt.

[0050] The discharge end of the conveying cylinder 13 is connected to a powder feeding pipe 131.

[0051] In use, the rotational power of the irregular impeller 32 in the transducer 3 is transmitted to the second synchronous wheel 15 by the first synchronous wheel 35, so that the auger 14 rotates. Thus, the auger 14 can push the activated carbon powder in the bucket cylinder 11 to the powder feeding pipe 131, thereby realizing synchronous feeding of the mixing component 5.

[0052] To ensure smooth mixing and spraying of water, air, and powder, for example, such as Figure 1-7 As shown, the present invention also includes the mixing assembly 5, which includes a venturi tube 51, a tee 52, and a discharge pipe 53 for connection to the sewage tank. The discharge end of the venturi tube 51 is connected to the discharge pipe 53. A gas-liquid interface 511 is provided at the end of the venturi tube 51 away from the discharge pipe 53. A powder interface 512 is connected to the top of the throat of the venturi tube 51. The feed end of the powder interface 512 is connected to the discharge end of the powder feeding pipe 131.

[0053] During use, the water supplied by the pump 4 is combined with the pulsed air pressure through the three-way valve 52 to accelerate the water flow into the venturi tube 51. Through the Venturi effect of the venturi tube 51, a negative pressure will be formed at the throat of the venturi tube 51. The activated carbon powder in the powder supply pipe 131 is drawn in through the powder interface 512 and pulsedly discharged into the sewage deodorization tank through the discharge pipe 53. The pulsed spraying makes the activated carbon better dispersed in the sewage, improving the deodorization effect. Moreover, the pulsed pressurization can prevent the mixing component 5 from clogging, ensuring the smooth mixing and spraying process of water, air and powder.

[0054] The three-way valve 52 includes a second water inlet pipe 521, an air inlet pipe 522, and an air-liquid manifold pipe 523. The second water inlet pipe 521 and the air inlet pipe 522 are respectively connected to both sides of the air-liquid manifold pipe 523. The discharge end of the air-liquid manifold pipe 523 is connected to the air-liquid interface 511.

[0055] The present invention also includes a drain pipe 42 connected to the drain end of the water pump 4, a first inlet pipe 41 connected to the water inlet end of the water pump 4, the water inlet end of the second inlet pipe 521 connected to the drain end of the drain pipe 42, and the air inlet end of the air inlet pipe 522 connected to the exhaust end of the exhaust nozzle 34.

[0056] One-way valves 54 are installed on the gas-liquid manifold 523, the second water inlet pipe 521, and the air inlet pipe 522.

[0057] In use, the water inlet of the water pump 4 can be connected to the water supply of the water treatment site through the first water inlet pipe 41, and the water discharged by the water pump 4 can be sent to the second water inlet pipe 521 in the mixing assembly 5 through the drain pipe 42.

[0058] To enable the water pump to operate based on the mechanical rotational force converted by the transducer, for example, such as Figure 1 , 2 As shown in Figures 3 and 5, the present invention further includes a third synchronous wheel 16 coaxially mounted on the end of the second synchronous wheel 15 away from the feed seat 12, and a fourth synchronous wheel 43 mounted on the end of the impeller input shaft of the water pump 4, the fourth synchronous wheel 43 being located on the outside of the housing of the water pump 4.

[0059] The third synchronous pulley 16 and the fourth synchronous pulley 43 are connected by a synchronous belt.

[0060] In use, the second synchronous wheel 15 drives the third synchronous wheel 16 to rotate, and the third synchronous wheel 16 drives the fourth synchronous wheel 43 on the impeller of the water pump 4 to rotate, so that the water pump 4 can operate based on the mechanical rotational force converted by the transducer 3.

[0061] In use, the inlet end of the first water inlet pipe 41 is connected to the water supply pipeline of the water treatment site, and the power supply component in the work site provides power to the electrical components of this application. During deodorization, compressed air is generated by the air pump 2 and sent into the air collection box 33 through the air inlet 331. The compressed air is sprayed onto the irregular impeller 32 through the first exhaust nozzle 332 and the second exhaust nozzle 333, driving it to rotate. The rotation of the irregular impeller 32 is transmitted to the first synchronous pulley 35 through the output shaft 36, which in turn drives the second synchronous pulley 15 to rotate. The auger 14 can push the activated carbon powder in the bucket-shaped cylinder 11 to the powder feeding pipe 131. At the same time, the second synchronous pulley 15 drives the third synchronous pulley 16 to rotate, and the third synchronous pulley 16 drives the fourth synchronous pulley 43 on the impeller of the water pump 4 to rotate. The water pump 4 operates based on the mechanical rotational force converted by the transducer 3. The water discharged from the water pump 4 enters the tee 52 through the second inlet pipe 521. After the air storage chamber 324 in the shaped impeller 32 reaches the exhaust nozzle 34, the pressure is released through the exhaust nozzle 34. Based on the alternating passage of the wedge-shaped blade 323 and the air storage chamber 324, the air discharged from the exhaust nozzle 34 will form a pulse airflow to discharge to the tee 52. The water flow and air flow enter the venturi tube 51 of the mixing component 5. The throat of the venturi tube 51 forms a negative pressure based on the venturi effect, which draws in activated carbon powder through the powder supply pipe 131 connected to the powder interface 512. After the activated carbon powder is mixed with air and water, it forms an activated carbon mixture. The activated carbon mixture is sprayed into the sewage deodorization treatment tank through the discharge pipe 53 in a pulse manner to achieve the deodorization operation of sewage.
