Technical Field

[0001] The utility model relates to the technical field of organic solid waste treatment, in particular to a biological deodorization device for organic solid waste treatment. Background Art

[0002] When organic solid waste is recycled, it usually undergoes composting fermentation. During this process, the odor substances generated are mainly ammonia, hydrogen sulfide, and some volatile organic pollutants. If directly discharged, it will pollute the air. Therefore, it is necessary to set up odor collection and treatment devices. Currently, many enterprises use the microbial deodorization method. However, the activities of microorganisms require suitable temperature, humidity, pH value, and oxygen. The existing biological deodorization devices do not have the function of changing the environment for microbial activity and reproduction.

[0020] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0021] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Such as Figures 1-4As shown in the figure, a biological deodorization device for organic solid waste treatment includes a humidification layer 1, a deodorization layer 2, an air inlet pipe 7, a water pump 9, and two air extractors 3. The air inlet pipe 7 is fixed at the air outlet of one of the air extractors 3, and one end of the air outlet penetrates and is fixed to the bottom of the humidification layer 1. The air inlet of one of the air extractors 3 is used to connect an oxygen supply machine and an odor pipe. The air inlet and outlet of the other air extractor 3 are respectively communicated with the humidification layer 1 and the deodorization layer 2. Both air extractors 3 are fixed on the outside of the humidification layer 1, and the fan shaft parts of both air extractors 3 are fixedly connected with bevel gears 5. The two bevel gears 5 are respectively meshed with the same double-headed bevel gear shaft 14. Two belt pulleys 15 are rotatably connected in the humidification layer 1 and are connected by a belt. One of the belt pulleys 15 is at the same height as the double-headed bevel gear shaft 14 and rotates at the same speed through the same driving member. The other belt pulley 15 is fixedly connected to the turbine main shaft of the water pump 9. The driving member includes a double-shaft motor 4 fixed on the outside of the humidification layer 1. One main shaft of the double-shaft motor 4 is fixedly connected to the end face of the double-headed bevel gear shaft 14, and the other main shaft extends into the humidification layer 1 and is fixedly connected to the end face of the belt pulley 15 arranged at the same height.

[0023] With this technical solution, after the air inlet pipe 7 of the device passes through the odor gas and the oxygen required for microbial metabolism, by setting the air inlet pipe 7 to communicate with the bottom of the humidification layer 1, when the odor gas and oxygen are discharged from the air inlet pipe 7 into the device, they first come into contact with the moisture in the humidification layer 1 and form bubbles, and can be contaminated with more moisture during the upward movement. And to make the odor gas and oxygen enter the device from the bottom of the humidification layer 1 requires additional pressure. By setting an air extractor 3 at the air inlet pipe 7, the gas can be pressed into the device. In addition, in order to make the device more energy-saving, by setting a double-shaft motor 4 to work, it can drive the water pump 9 and the two air extractors 3 to work. Specifically, when the double-shaft motor 4 works, its two main shafts drive the double-headed bevel gear shaft 14 and the belt pulley 15. The double-headed bevel gear shaft 15 drives the two bevel gears 5 to rotate. The two bevel gears 5 rotate respectively to drive the fan shaft parts of the two air extractors 3 to rotate. Since the two belt pulleys 15 are driven by a sleeved belt, both belt pulleys 15 will rotate, driving the turbine part of the water pump 9 to rotate, so as to drive the two air extractors 3 and the water pump 9 to work. It should be added that all penetrations and connections on the device are mechanically sealed to prevent water leakage and air leakage.

[0024] As Figure 4 shown, the double-headed bevel gear shaft 14 is divided into two equal parts at the middle position, and a speed changer 6 fixed on the humidification layer 1 is arranged at the disconnection position. The input shaft of the speed changer 6 is fixedly connected to the part of the double-headed bevel gear shaft 14 close to the double-shaft motor 4, and the output shaft is fixedly connected to the part of the double-headed bevel gear shaft 14 far from the double-shaft motor 4.

[0025] With this technical solution, during the process of using the dual-axis motor 4 to drive the two air extractors 3 and the water pump 9, since the air extractor 3 located at the air inlet pipe 7 requires more powerful power to pump oxygen and odor into the device, the rotational speed of its fan shaft part needs to be faster. Therefore, by setting the speed reducer 6, with the rotational speed of its input shaft remaining unchanged, after the adjustment of the speed reducer 6, the rotational speed of its output shaft obtains a faster speed, thereby driving the rotational speed of part of the double-headed bevel gear shaft 14 to increase, driving the rotational speed of the bevel gear 5 to increase, and the increased rotational speed of the bevel gear 5 ultimately drives the fan shaft part of the air extractor 3 to obtain a faster rotational speed.

[0026] As Figure 2 shown, a culture dish 12 is placed at the bottom of the deodorizing layer 2, and a slow-speed motor 13 is fixedly connected to the top of the deodorizing layer 2. A stirring rod 10 for stirring microorganisms is fixedly connected to the main shaft of the slow-speed motor 13.

[0027] With this technical solution, by setting the stirring rod 10, the microorganisms on the culture dish 12 are continuously stirred under the drive of the slow-speed motor 13, increasing the contact area between the microorganisms and the odor and oxygen, improving the metabolic rate of the microorganisms, and thus increasing the deodorizing efficiency of the device.

[0028] As Figure 1 shown, an electric sprayer 11 is arranged on the deodorizing layer 2, and a citric acid solution is contained in the electric sprayer 11.

[0029] With this technical solution, since the existing odor contains substances such as ammonia that are easily soluble in water and will produce a weakly alkaline solution, after the odor is humidified and drawn into the deodorizing layer 2, the pH value in the deodorizing layer 2 will increase. And the growth of microorganisms requires an appropriate pH environment, generally close to neutral. Therefore, by setting the electric sprayer 11, the citric acid solution is sprayed into the microbial community on the culture dish 12 to carry out an acid-base neutralization reaction with alkaline solutions such as ammonia water, reducing the pH value of the deodorizing layer 2 in the device, thereby enhancing the activity of the microorganisms, improving the metabolic rate of the microorganisms, and increasing the deodorizing efficiency of the device.

[0030] As Figure 2 shown, an air diffuser 8 is fixedly connected to the bottom of the humidifying layer 1, and the air inlet of the air diffuser 8 is fixedly connected to the nozzle of the air inlet pipe 7.

[0031] With this technical solution, by setting the air diffuser 8, the contact area between the odor and oxygen and water is increased, enabling the gas to be fully humidified.

[0032] Working principle: When the double-shaft motor 4 operates, the two main shafts drive the double-headed bevel gear shaft 14 and the pulley 15 to rotate. The double-headed bevel gear shaft 15 drives the two bevel gears 5 to rotate. The rotation of the two bevel gears 5 respectively drives the fan blade parts of the two air extractors 3 to rotate. The rotation of the pulley 15 drives the turbine part of the water pump 9 to rotate, thereby driving the two air extractors 3 and the water pump 9 to operate. The air extractor 3 located at the intake pipe 7 operates to press the odor and oxygen into the device. Under the action of the other air extractor 3 after the gas is humidified by water, the gas is sent into the deodorization layer 2, and the harmful substances in the odor are absorbed through microbial metabolism by absorbing the odor and oxygen.

[0033] The wiring diagrams of the air extractor 3, the double-shaft motor 4, the speed changer 6, the water pump 9, the electric sprayer 11 and the slow motor 13 in the present utility model belong to the common knowledge in the art. Their working principles are already well-known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the air extractor 3, the double-shaft motor 4, the speed changer 6, the water pump 9, the electric sprayer 11 and the slow motor 13 will not be explained in detail.

[0034] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still belong to the protection scope of the technical solution of the present utility model.
