Description

Technical Field

[0001] This utility model relates to the field of experimental device technology, specifically to an experimental device for research on deodorization of livestock and poultry houses. Background Technology

[0002] With the large-scale development of livestock and poultry farming, the pollution caused by odors from livestock and poultry sheds has become increasingly serious. These odors not only affect the health of operators but also impact the quality of life of surrounding residents, becoming a focal point of social concern. Odor complaints account for the highest proportion of environmental complaints related to livestock farming, making effective odor emission control a major challenge for the industry. Directly implementing deodorization devices in actual production may require replacement due to poor deodorization performance, which is not only costly but also irreversible in terms of damage caused. Therefore, an experimental device is needed to test the deodorization effect of deodorization devices. For example, patent document CN102128887A provides a biological filtration deodorization experimental device that can determine the deodorization effect by analyzing various data changes at the inlet and outlet. However, these devices often cannot simulate the actual livestock and poultry shed environment, leading to certain errors in the experimental data and failing to accurately reflect the effectiveness of the deodorization device in practical applications.

[0020] The air intake assembly includes a drive motor 13 and an air intake window 5 that runs through the odor generation chamber 1 on the side away from the flexible duct 4.

[0021] An air inlet 14 is formed on the side of the deodorizing chamber 2 closest to the flexible pipe 4, and an air outlet 15 is provided on the side of the deodorizing chamber 2 away from the flexible pipe 4. A pulley 18 is provided at the bottom of the deodorizing chamber 2.

[0022] The electrical equipment includes an airflow control component, a pressure monitoring component, and an odor monitoring component. The airflow control component is used to adjust the exhaust volume of odor generation chamber 1 and deodorization chamber 2 so that the exhaust volume of odor generation chamber 1 and deodorization chamber 2 is consistent with the exhaust volume of a single fan in the actual production livestock and poultry house. The pressure monitoring component is used to monitor the pressure in odor generation chamber 1 and deodorization chamber 2. The odor monitoring component is used to monitor the odor removal rate of the deodorization facility studied in deodorization chamber 2.

[0023] The airflow control component includes a wind speed sensor 6 installed at the airflow generation point of the air inlet component inside the odor generation chamber 1, and a negative pressure exhaust fan 7 installed in the flexible duct 4. The wind speed sensor 6 is used to monitor the wind speed generated by the air inlet component (the wind speed sensor 6 has various embodiments in the prior art, and its specific structure will not be described in detail here). The negative pressure exhaust fan 7 is used to regulate the airflow speed entering the deodorization chamber 2 (the negative pressure exhaust fan 7 has various embodiments in the prior art, and its specific structure will not be described in detail here).

The drive motor controller 23 is electrically connected to the drive motor 13. The negative pressure exhaust fan frequency converter 24 is electrically connected to the negative pressure exhaust fan 7. The airflow speed transmitted by the wind speed sensor 6 is used to synchronously adjust the opening angle of the louvers 12 and the speed of the negative pressure exhaust fan 7 through the drive motor controller 23 and the negative pressure exhaust fan frequency converter 24, so that the exhaust volume of the odor generation chamber 1 is consistent with the exhaust volume of a single fan in the actual production of livestock and poultry houses (the wind speed monitoring instrument 22, drive motor controller 23 and negative pressure exhaust fan frequency converter 24 have various embodiments in the prior art, and the specific structure of the wind speed monitoring instrument 22, drive motor controller 23 and negative pressure exhaust fan frequency converter 24 will not be described in detail here).

The first pressure sensor 11 and the second pressure sensor 17 transmit the wind resistance values ​​measured in the odor generation chamber 1 and the deodorization chamber 2 to the pressure monitoring system 20, thereby moving the distance between the deodorization chamber 2 and the odor generation chamber 1 through the pulley 18, so that the deodorization facility studied meets the pressure load requirements of the negative pressure exhaust fan of the livestock and poultry house in actual production (the first pressure sensor 11, the second pressure sensor 17 and the pressure monitoring system 20 have various embodiments in the prior art, and the specific structure of the first pressure sensor 11, the second pressure sensor 17 and the pressure monitoring system 20 will not be described in detail here).

[0025] The odor monitoring component includes a first odor sensor 8 disposed in the air inlet 14 and a second odor sensor 16 disposed in the air outlet 15. An odor monitoring system 21 is disposed in the control cabinet 3. The odor monitoring system 21 is electrically connected to the first odor sensor 8 and the second odor sensor 16 respectively. The first odor sensor 8 and the second odor sensor 16 transmit the information on the content of odor molecules in the detected gas to the odor monitoring system 21. Thus, the odor removal rate of the deodorization facility studied in the deodorization chamber 2 can be detected by comparing the information of the first odor sensor 8 and the second odor sensor 16 (the first odor sensor 8, the second odor sensor 16 and the odor monitoring system 21 have various embodiments in the prior art. The specific structure of the first odor sensor 8, the second odor sensor 16 and the odor monitoring system 21 will not be described in detail here).

[0026] Specifically, the feed trough 9 and waterer 10 provide feed and water for livestock, ensuring their normal growth. The first odor sensor 8 and odor monitoring system 21 monitor the odor generated in the odor-generating chamber 1, ensuring it represents the odor concentration and characteristic animal odor in the actual livestock room. Airflow is regulated by the negative pressure exhaust fan 7: the wind speed sensor 6 and wind speed monitor 22 accurately reflect the airflow speed at the air inlet window 5 in the odor-generating chamber 1; and the drive motor controller 23 and the negative pressure exhaust fan frequency converter 24 synchronously adjust the opening angle of the louvers 12 and the negative pressure exhaust fan. The 7-speed rotation allows for precise control of the exhaust volume of the odor-generating chamber 1 to match the exhaust volume of a single fan in a livestock and poultry house during actual production. The pressure monitoring system 20 accurately feeds back the wind resistance value of the deodorization chamber 2, and the pulley 18 moves back and forth to adjust the distance between the deodorization chamber 2 and the negative pressure exhaust fan 7, ensuring that the deodorization facility meets the pressure load requirements of the negative pressure exhaust fan in a livestock and poultry house during actual production. The odor generated in the odor-generating chamber 1 is discharged into the deodorization chamber 2 through the negative pressure exhaust fan 7, and the odor removal rate of the deodorization facility in the deodorization chamber 2 is accurately detected by the odor monitoring system 21, enabling rapid evaluation.

Through the electrical equipment placed in the deodorization chamber 2, the control cabinet 3 can judge the deodorization effect of the deodorization device in the deodorization chamber based on the received information.
