[0002] With the rapid development of my country's modern economy and the continuous improvement of urbanization, the rapid development of industrial and agricultural industries has brought about many environmental pollution problems. Odor pollution has caused pollution and damage to the surrounding ecological environment, seriously affecting the production and life of nearby related enterprises, and affecting people's health. Odor pollution has also led to an increase in the protection distance of surrounding polluting enterprises, a decrease in the utilization rate of land resources, and a waste of land resources.

[0003] However, existing online odor gas monitoring devices rely on a single monitoring method and cannot quickly distinguish the components in odorous gases, thus reducing the detection efficiency of odorous gases. Therefore, we propose an online odor gas monitoring device to solve the above-mentioned problems. Utility Model Content

[0013] This invention provides an online monitoring device for odorous gases. Compared with the prior art, it has the following advantages: This online odor gas monitoring device can be fixed in a designated position via a base in a cabinet, or installed on the cabinet door and back panel. The back panel can then be used to install and fix components such as filters and air pumps, thereby improving its stability. When odor gas needs to be detected, the air pump can be controlled by a PLC module. The air pump draws the gas to be tested from the outside through the air inlet pipe.

[0016] 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.

[0017] Please see Figures 1-3This utility model provides a technical solution: an online odor gas monitoring device, including a cabinet 1, a base 2 fixedly installed at the bottom of the cabinet 1, a cabinet door 3 installed at the open end of the cabinet 1, a back plate 4 fixedly installed in the upper part of the inner cavity of the cabinet 1, a filter 5, an air pump 6, a gas-water separator 7 and a rotor flow meter 8 sequentially installed on the surface of the back plate 4 near the bottom, a digital display ammonia sensor module 9, a digital display hydrogen sulfide sensor module 10 and a digital display odor sensor module 11 sequentially installed in the middle of the surface of the back plate 4, and a digital display TVOC sensor installed on the surface of the back plate 4 between the gas-water separator 7 and the rotor flow meter 8. 12. Filter 5, air pump 6, steam-water separator 7, rotor flow meter 8, digital display ammonia sensor module 9, digital display hydrogen sulfide sensor module 10, digital display odor sensor module 11 and digital display TVOC sensor 12 are connected in sequence through connecting pipes; the air inlet end of filter 5 is connected to air inlet pipe 13, and the air outlet end of digital display TVOC sensor 12 is connected to air outlet pipe 14. On the surface of back panel 4 and near the top, air switch 18, surge protector 19, power adapter 20, PLC module 21 and cloud box 22 are arranged in sequence. On the surface of cabinet door 3 and near the top, touch screen display 23 is embedded. The cabinet 1 allows for both mounting on the base 2 and installation of the cabinet door 3 and back panel 4. The back panel 4 then houses components such as the filter 5 and air pump 6, enhancing operational stability. When odor detection is required, the PLC module 21 controls the air pump 6, drawing in the target gas through the inlet pipe 13. This gas is first filtered by the filter 5, then pressurized by the air pump 6 and flows sequentially through the gas-water separator 7, rotor flow meter 8, digital ammonia sensor module 9, digital hydrogen sulfide sensor module 10, digital odor sensor module 11, and TVOC sensor 12, finally exiting the cabinet 1 through the outlet pipe 14. The gas-water separator 7 then removes water from the gas. The system separates the gases, allowing the pure gas to be delivered to subsequent components. Then, through a rotor flowmeter 8, a digital display ammonia sensor module 9, a digital display hydrogen sulfide sensor module 10, a digital display odor sensor module 11, and a TVOC sensor 12, the flow rate, ammonia concentration, hydrogen sulfide concentration, odor concentration, and TVOC concentration of the passing gas can be monitored. The monitoring data can also be sent to a PLC module 21. The PLC module 21 can then display the monitoring data on a touch screen 23 and transmit the data to a platform via a cloud box 22, allowing users to view it in real time on the client side. An air switch 18 provides overload protection, a surge protector 19 provides lightning protection, and a power adapter 20 converts the voltage to supply power to the equipment.

[0018] See Figures 1-3 The air inlet end of the air inlet pipe 13 and the air outlet end of the air outlet pipe 14 both penetrate the side wall of the cabinet 1 and extend to the outside of the cabinet 1, which can facilitate the intake of the external gas to be tested into the subsequent sensors for detection.

[0019] See Figure 3 The back panel 4 has a cable tray 15 in the middle of its surface for fixing and organizing the power cords and signal cables of the equipment, which can organize the power cords and signal cables of the equipment in a standardized manner.

[0020] See Figure 3 The drain end of the steam-water separator 7 is connected to a drain pipe 16, and the bottom of the drain pipe 16 is connected to a water storage box. One side of the water storage box is connected to the inner wall of the cabinet 1. Through the drain pipe 16, the water separated by the steam-water separator 7 can be guided to the water storage box, so that users can centrally process this part of the water.

[0021] See Figure 3 The surface of the back plate 4 and near the top are fixedly provided with a mounting rail 17 for mounting the air switch 18, surge protector 19, power adapter 20, PLC module 21 and cloud box 22. The mounting rail 17 provides a stable support base for the air switch 18, surge protector 19, power adapter 20, PLC module 21 and cloud box 22.

[0022] See Figure 1 , Figure 2 A light 24 is installed at the top of the surface of the cabinet 1. The light 24 can provide illumination for the equipment, thereby making it easier for staff to view and operate the touch screen 23.

[0023] See Figure 1 , Figure 2 Ventilation holes 25 are provided on both sides of the cabinet 1 at the same height as the back panel 4. A cooling fan is provided on the inner wall of the cabinet 1 at the ventilation holes 25. The cooling fan, in conjunction with the ventilation holes 25, can dissipate heat inside the cabinet 1, thereby improving the safety of the internal equipment.

[0024] See Figures 1-3 The air inlet pipe 13, air outlet pipe 14, connecting pipes, and drain pipe 16 are all made of PTFE, which can reduce the corrosion of the pipes by corrosive gases and thus improve the service life of each pipe.

[0025] During operation, the cabinet 1 can be fixed in a designated position via the base 2, and the cabinet door 3 and back panel 4 can be installed. The back panel 4 then allows for the installation and fixation of components such as the filter 5 and air pump 6, thus improving operational stability. When odorous gases need to be detected, the PLC module 21 controls the air pump 6 to draw in the gas to be tested through the inlet pipe 13. This gas is first filtered by the filter 5, and then pressurized by the air pump 6, flowing sequentially through the steam-water separator 7, the rotor flow meter 8, the digital display ammonia sensor module 9, the digital display hydrogen sulfide sensor module 10, the digital display odor sensor module 11, and the TVOC sensor 12, finally exiting the cabinet 1 through the outlet pipe 14. The steam-water separator 7 then allows for the detection of odorous gases in the gas. The moisture is separated, allowing the pure gas to be delivered to subsequent components. Then, through the rotor flow meter 8, digital display ammonia sensor module 9, digital display hydrogen sulfide sensor module 10, digital display odor sensor module 11, and TVOC sensor 12, the flow rate, ammonia concentration, hydrogen sulfide concentration, odor concentration, and TVOC concentration of the flowing gas can be monitored. The monitoring data can also be sent to the PLC module 21. At this time, the PLC module 21 can send the monitoring data to the touch screen 23 for display, and can also transmit the data to the platform via the cloud box 22, so that users can view it in real time on the client side. Overload protection is provided by the air switch 18, and lightning protection is provided by the surge protector 19. The voltage can be converted by the power adapter 20 to supply power to the equipment.

[0026] Cable tray 15 allows for the standardized organization of power and signal cables. Drain pipe 16 guides the water separated by steam-water separator 7 to a water storage box, facilitating centralized water treatment by the user. Fixed rail 17 provides a stable support base for air switch 18, surge protector 19, power adapter 20, PLC module 21, and cloud box 22. Lighting 24 provides illumination for the equipment, making it easier for staff to view and operate the touch screen 23. Cooling fan and ventilation holes 25 provide heat dissipation for the interior of cabinet 1, improving the safety of internal equipment. Since the air inlet pipe 13, air outlet pipe 14, connecting pipes, and drain pipe 16 all use PTFE pipes, the corrosion of the pipes by corrosive gases is reduced, thereby extending the service life of each pipe.

[0027] In summary, this device can perform diversified monitoring of odorous gases, improving the efficiency of odorous gas monitoring, and also allows users to conveniently view the data remotely online, thus enhancing the ease of use of the equipment.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
