Description

Technical Field

[0001] This utility model relates to the field of wastewater and waste gas treatment technology, specifically to a sterilization and deodorization device for wastewater and waste gas. Background Technology

[0002] The main purpose of wastewater treatment equipment is to treat domestic sewage and similar industrial organic wastewater to meet the requirements for reuse water quality, so as to make the wastewater resources available after treatment. Based on summarizing advanced experience at home and abroad, wastewater treatment processes are continuously improved, which promotes the great development of wastewater treatment equipment.

[0003] Currently, wastewater disinfection and sterilization facilities simply use sodium hypochlorite to reduce dust in wastewater, making the treated water unusable for direct use. Furthermore, the ultraviolet lamps used for sterilization are typically placed on the surface of the pool, which is inconvenient when water needs to be treated. In addition, the sodium hypochlorite introduced by traditional treatment facilities is too concentrated, failing to achieve rapid and comprehensive dust reduction and disinfection.

[0004] As disclosed in Chinese Patent CN218371852U, a wastewater disinfection and sterilization mechanism involves a motor driving a shaft to push a movable plate, activating an ultraviolet lamp to achieve sterilization. Upon termination, the motor reverses direction, causing the shaft to wind a connecting strip and the movable plate onto it, thus completing the secondary treatment and sterilization of the wastewater. Ultraviolet light sterilizes the pre-treated water, making it usable directly. The ultraviolet lamp can be extended during use and retracted afterward, facilitating its convenient use and avoiding inconvenience during subsequent water treatment. Chlorine gas is discharged through a dispersion pipe, making extensive contact with the wastewater to disinfect harmful substances. A filter removes these substances, and the water flows into the sterilization tank through a water pipe after the pump, completing the pre-treatment and disinfection of the wastewater. By increasing the contact area between chlorine and harmful substances in the wastewater, most harmful substances are quickly eliminated. Furthermore, pre-treatment and adsorption facilitate sterilization during secondary treatment.

[0005] However, waste gas is generated during wastewater treatment, and the device cannot collect and treat the waste gas, which will be directly emitted into the air and cause pollution.

[0006] Therefore, we urgently need to provide a sterilization and deodorization device for wastewater and exhaust gas. Utility Model Content

[0007] The purpose of this invention is to provide a sterilization and deodorization device for wastewater exhaust gas, in order to solve the problem mentioned in the background art that when wastewater is treated, exhaust gas is generated, and the device cannot collect and treat the exhaust gas, which will be directly discharged into the air and cause pollution.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a sterilization and deodorization device for wastewater and exhaust gas, comprising a treatment box and a support rod, wherein the support rod is disposed at the right end of the treatment box, and a treatment tank is fixedly connected to the upper end of the support rod; a treatment mechanism is connected to the inner and outer ends of the treatment box and the treatment tank, wherein the treatment mechanism comprises a treatment unit and a replacement unit, wherein the treatment unit is disposed at the inner and outer ends of the treatment box and the treatment tank, and the replacement unit is disposed at the upper end of the treatment box.

[0009] The treatment unit includes a wastewater inlet pipe, a chlorine inlet pipe, a cap, a discharge pipe, a motor, a stirring shaft, a vent pipe, a water storage tank, a spray head, an air outlet pipe, a discharge pipe, and an ultraviolet lamp. The wastewater inlet pipe is fixedly connected to the rear left side of the treatment tank, the chlorine inlet pipe is fixedly connected to the front left side of the treatment tank, the cap is connected to the upper ends of the wastewater inlet pipe and the chlorine inlet pipe, the discharge pipe is fixedly connected to the lower left side of the treatment tank, and a valve is installed inside the discharge pipe. The motor is fixedly connected to the middle of the upper side of the treatment tank, the stirring shaft is fixedly connected to the lower end of the motor's output shaft, the vent pipe is fixedly connected to the upper right side of the treatment tank, the water storage tank is fixedly connected to the upper end of the treatment tank, the spray head is fixedly connected to the lower end of the water storage tank, the air outlet pipe is fixedly connected to the upper right side of the treatment tank, the discharge pipe is fixedly connected to the lower end of the treatment tank, and the ultraviolet lamp is fixedly connected to the left and right sides of the inner side of the treatment tank.

[0010] A further improvement is that the upper outer sides of the wastewater inlet pipe and the chlorine inlet pipe are provided with external threads, and the inner side of the cover is provided with internal threads. The upper outer sides of the wastewater inlet pipe and the chlorine inlet pipe are connected to the inner thread of the cover, thereby connecting the cover threadedly to the upper outer sides of the wastewater inlet pipe and the chlorine inlet pipe, and sealing the upper ends of the wastewater inlet pipe and the chlorine inlet pipe.

[0011] A further improvement is that the upper right end of the vent pipe is fixedly connected to the lower left end of the inside of the treatment tank, so that the deodorant mixture in the water storage tank can be sprayed out through the spray head to spray and deodorize the exhaust gas entering the treatment tank.

[0012] A further improvement is that the replacement unit includes a filter screen, a limiting rod, a top plate, a spring, and a pressure plate. The filter screen is fixedly connected to the inner side of the vent pipe, the limiting rod is fixedly connected to the upper outer side of the vent pipe, the top plate is fixedly connected to the upper end of the limiting rod, the spring is fixedly connected to the lower side of the top plate, and the pressure plate is fixedly connected to the lower end of the spring.

[0013] A further improvement is that sliding holes are provided at both the left and right ends of the pressure plate, and the outer side of the limiting rod is slidably connected to the inner side of the sliding hole, so that when the spring bounces, it can drive the pressure plate at the lower end to slide along the outer side of the limiting rod.

[0014] A further improvement is that a groove is provided at the upper end of the vent pipe, and the lower side of the pressure plate abuts against the outer side of the vent pipe at the groove. There are two filters, and the two filters are fixed to the left and right ends of the groove on the inner side of the vent pipe, respectively. Activated carbon is placed between the two filters. After the activated carbon is placed in the vent pipe between the filters, the pressure plate is pushed down by the spring, so that the lower end of the pressure plate contacts the groove on the outer side of the vent pipe, thus sealing the groove.

[0015] A further improvement is that a rubber pad is fixedly connected to the lower side of the pressure plate, so that after the lower side of the pressure plate contacts the outer groove of the vent pipe, the surface of the vent pipe is contacted by the rubber pad, which can keep the contact between the pressure plate and the vent pipe sealed.

[0016] In summary, this application discloses a sterilization and deodorization device for wastewater and exhaust gas.

[0017] This technical solution uses a vent pipe at the top of the treatment tank to allow the waste gas generated from the wastewater treatment to enter the treatment tank. The gas is then filtered and sterilized by activated carbon in the vent pipe. A mixture of deodorizing agents from a storage tank is sprayed through a spray nozzle to deodorize the waste gas entering the treatment tank before it is discharged through the vent pipe at the top of the treatment tank. This process treats the waste gas generated from the wastewater treatment before it is released, thus preventing any environmental impact.

[0018] Furthermore, by pulling up the pressure plate to move it away from the channel along the limit rod, the expired activated carbon between the filter screens can be removed from the channel. Then, new activated carbon can be placed between the filter screens. Next, the pressure plate spring is released and the pressure plate is pushed back down, pushing the pressure plate to the channel outside the vent pipe, thus resealing the vent pipe. This allows the activated carbon to be replaced after long-term use and failure. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution: Example

[0026] A sterilization and deodorization device for wastewater and exhaust gas includes a treatment box 1 and a support rod 2. The support rod 2 is located at the right end of the treatment box 1, and a treatment tank 3 is fixedly connected to the upper end of the support rod 2. Treatment mechanisms are connected to the inner and outer ends of the treatment box 1 and the treatment tank 3. The treatment mechanism includes a treatment unit and a replacement unit. The treatment unit is located at the inner and outer ends of the treatment box 1 and the treatment tank 3, and the replacement unit is located at the upper end of the treatment box 1.

[0027] The treatment unit includes a wastewater inlet pipe 401, a chlorine water inlet pipe 402, a cover 403, a discharge pipe 404, a motor 405, a stirring shaft 406, a vent pipe 407, a water storage tank 408, a spray head 409, an air outlet pipe 410, a discharge pipe 411, and an ultraviolet lamp 412. The wastewater inlet pipe 401 is fixedly connected to the rear left end inside the treatment tank 1, and the chlorine water inlet pipe 402 is fixedly connected to the front left end inside the treatment tank 1. The cover 403 is connected to the upper ends of the wastewater inlet pipe 401 and the chlorine water inlet pipe 402. The outer side of the upper end of the wastewater inlet pipe 401 and the chlorine water inlet pipe 402 is provided with external threads, and the inner side of the cover 403 is provided with internal threads. The outer side of the upper end of the wastewater inlet pipe 401 and the chlorine water inlet pipe 402 is connected to the inner side of the cover 403 by threads. Therefore, after the wastewater and chlorine water are poured into the treatment tank 1 from the wastewater inlet pipe 401 and the chlorine water inlet pipe 402, the cap 403 is threaded to the upper outside of the wastewater inlet pipe 401 and the chlorine water inlet pipe 402 to seal the upper ends of the wastewater inlet pipe 401 and the chlorine water inlet pipe 402, which can prevent the waste gas generated during wastewater treatment from flowing out of the wastewater inlet pipe 401 and the chlorine water inlet pipe 402 and polluting the environment.

[0028] The discharge pipe 404 is fixedly connected to the lower left side of the inside of the treatment tank 1. A valve is installed inside the discharge pipe 404. The motor 405 is fixedly connected to the middle position on the upper side of the treatment tank 1. The stirring shaft 406 is fixedly connected to the lower end of the output shaft of the motor 405. The vent pipe 407 is fixedly connected to the upper right side of the inside of the treatment tank 1. The water storage tank 408 is fixedly connected to the upper end of the treatment tank 3. The spray head 409 is fixedly connected to the lower end of the water storage tank 408. The upper right end of the vent pipe 407 is fixedly connected to the lower left side of the inside of the treatment tank 3. Thus, the waste gas generated during the wastewater treatment in the treatment tank 1 will flow into the treatment tank 3 through the vent pipe 407. Then, the deodorizing agent mixture in the water storage tank 408 will be sprayed out through the spray head 409 to spray and deodorize the waste gas entering the treatment tank 3. Finally, it will be discharged from the vent pipe 410 at the upper end of the treatment tank 3.

[0029] The vent pipe 410 is fixedly connected to the upper right side of the inside of the treatment tank 3, the discharge pipe 411 is fixedly connected to the lower end of the inside of the treatment tank 3, and the ultraviolet lamp 412 is fixedly connected to the left and right ends of the inside of the treatment box 1. Example

[0030] Based on Embodiment 1: The replacement unit includes a filter screen 501, a limiting rod 502, a top plate 503, a spring 504, and a pressure plate 505. The filter screen 501 is fixedly connected to the inner side of the vent pipe 407, the limiting rod 502 is fixedly connected to the upper outer side of the vent pipe 407, the top plate 503 is fixedly connected to the upper end of the limiting rod 502, the spring 504 is fixedly connected to the lower side of the top plate 503, and the pressure plate 505 is fixedly connected to the lower end of the spring 504. Sliding holes are provided at both the left and right ends of the pressure plate 505, and the outer side of the limiting rod 502 is slidably connected to the inner side of the sliding hole. Therefore, when the spring 504 springs, it can drive the lower pressure plate 505 to slide along the outer side of the limiting rod 502, thereby limiting the movement of the pressure plate 505.

[0031] A groove is provided at the upper end of the vent pipe 407. The lower side of the pressure plate 505 abuts against the outer side of the vent pipe 407 at the groove. There are two filter screens 501, which are fixed to the left and right ends of the groove inside the vent pipe 407, respectively, with activated carbon stored between the two filter screens 501. After the activated carbon is placed inside the vent pipe 407 between the filter screens 501, the pressure plate 505 is pushed down by the spring 504, so that the lower end of the pressure plate 505 contacts the groove on the outside of the vent pipe 407, thus sealing the groove and storing the activated carbon. After the activated carbon has been used for a long time and has become ineffective, it can be removed from the groove and replaced by pulling the pressure plate 505 away from the groove.

[0032] A rubber pad is fixedly connected to the lower side of the pressure plate 505. Thus, after the lower side of the pressure plate 505 contacts the outer groove of the vent pipe 407, the rubber pad contacts the surface of the vent pipe 407, ensuring a seal at the contact point between the pressure plate 505 and the vent pipe 407. This guarantees that all the waste gas entering the vent pipe 407 will flow into the treatment tank 3 and will not leak out from the groove.

[0033] Working principle: In use, wastewater and chlorine water are first poured into treatment tank 1 through wastewater inlet pipe 401 and chlorine water inlet pipe 402, respectively. Then, the cap 403 is threaded to the upper end of wastewater inlet pipe 401 and chlorine water inlet pipe 402. Next, the motor 405 and the ultraviolet lamp 412 in treatment tank 1 are started. The output shaft of motor 405 rotates, driving the stirring shaft 406 to rotate, stirring the wastewater and chlorine water in treatment tank 1. At the same time, the exhaust gas generated by the wastewater treatment enters the upper vent pipe 407. After being sterilized and disinfected by the activated carbon between the filter screens 501 in the vent pipe 407, it enters treatment tank 3. At the same time, the spray head 409 is turned on to spray the deodorant mixture in the water storage tank 408 to spray and deodorize the exhaust gas entering treatment tank 3, and then it is discharged from the upper vent pipe 410 of treatment tank 3.
