[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0019] The present invention provides Figures 1 to 6 The air ammonia monitoring instrument for environmental monitoring shown in the figure comprises: a base 1, two support columns 2 are fixedly connected to the top of the base 1, a bottom cover 3 is fixedly connected to the top of the two support columns 2, a device tank 4 is fixedly connected to the top of the bottom cover 3, a top cover 5 is hingedly connected to the top of the device tank 4 through a pin shaft seal, and a control box 6 is arranged outside the device tank 4; The air suction component includes a motor 7 fixedly connected to the outside of the device tank 4, the output end of the motor 7 is fixedly connected to a pump body 8, the top of the pump body 8 is provided with an air suction pipe 9, the bottom of the pump body 8 is connected to an air outlet hood 10, the top of the air suction pipe 9 is clamped with a universal joint 11, the top of the universal joint 11 is rotatably connected with a telescopic pipe 12, the outside of the telescopic pipe 12 is provided with an electric flow meter 13, the outside of the electric flow meter 13 is fixedly connected with an electric push rod 14, the telescopic end of the electric push rod 14 is fixedly connected with a fixing sleeve 15, and the fixing sleeve 15 is clamped on the telescopic end of the telescopic pipe 12; The rotating assembly includes a first bevel gear 16 fixedly connected to the outside of the output end of the motor 7, a second bevel gear 17 meshing outside the first bevel gear 16, a fixed shaft 18 fixedly connected inside the second bevel gear 17, a driving wheel 19 fixedly connected to the bottom end of the fixed shaft 18, the driving wheel 19 is connected to the driven wheel 20 through an anti-slip conveyor belt transmission, a rotating shaft 21 is fixedly connected inside the driven wheel 20, and a rotating rod 22 is fixedly connected to the top of the rotating shaft 21; The cleaning assembly includes a connecting shaft 23 rotatably connected to the rotating rod 22, a rotating gear 24 is fixedly connected to the bottom of the connecting shaft 23, a cleaning brush 25 is fixedly connected to the top of the connecting shaft 23, a gear ring seat 26 is fixedly connected to the bottom cover 3, and the rotating gear 24 is meshed in the gear ring seat 26; When the instrument is running, the rotation of the rotating rod 22 will drive the connecting shaft 23 and the cleaning brush 25 to move together. The cleaning brush 25 is in close contact with the sensor surface, effectively removing dust, dirt and other impurities that may affect the performance of the sensor. This automatic cleaning mechanism significantly reduces the measurement error caused by sensor surface contamination, while also extending the service life of the sensor, reducing the frequency of sensor replacement and maintenance costs.
[0020] The fixed shaft 18 is rotatably connected in the bottom cover 3 , the rotating shaft 21 is rotatably connected with a connecting rod 27 outside, the connecting rod 27 is fixedly connected in the bottom cover 3 , the fixed shaft 18 is connected with a connecting sleeve 28 outside, and the connecting sleeve 28 is fixedly connected in the device tank 4 .
[0021] A plurality of photochemical sensors 29 are evenly distributed in the device tank 4. These photochemical sensors 29 use a light source of a specific wavelength to illuminate the air sample. When ammonia molecules pass through the sensor, they will have a specific optical reaction with the light source. The sensor calculates the concentration of ammonia by detecting these reactions. Due to the design and arrangement of the sensors, the instrument can provide high-precision ammonia concentration measurement results, which is crucial for fields such as environmental monitoring and industrial control. The universal joint 11 is snapped into the top cover 5, a fixing seat 30 is provided outside the pump body 8, the fixing seat 30 is fixedly connected in the device tank 4, the shape of the air outlet hood 10 is an inverted cone, and a plurality of air outlets are annularly distributed outside the air outlet hood 10, the cleaning brush 25 abuts against the outside of a plurality of photochemical sensors 29, the bottom of the bottom cover 3 is connected to an air outlet pipe 31, and the right end of the air outlet pipe 31 is connected to a water tank 32.
[0022] The water tank 32 has a water inlet at the top and a water outlet at the right side. The water tank 32 serves as a medium for dissolving ammonia. The material and structure of the water tank 32 can resist the corrosiveness of ammonia water, while ensuring that ammonia can be effectively dissolved in water. The water dissolved with ammonia in the water tank 32 needs to be discharged through a heating system, and the heating system generally includes a heating element (such as an electric heater) and a temperature control system.
[0023] Heating process: The heating system heats the ammonia water in the water tank 32 to a certain temperature so that the ammonia gas dissolved in the water escapes. During the heating process, the ammonia gas is released from the water and converted into gas.
[0024] Emission treatment: The escaping ammonia is directed to the exhaust system through the exhaust pipe. This system may include filtration, adsorption or other treatment methods to ensure that the exhausted ammonia does not pollute the environment.
[0025] Environmental impact reduction: By dissolving ammonia in water and heating it to discharge, the monitoring instrument effectively reduces the impact of direct ammonia emissions on the environment. This method not only reduces the concentration of ammonia, but also may further reduce the amount of ammonia emissions through subsequent treatment steps; The water tank 32 is fixedly connected to the top of the base 1. Four self-locking universal wheels 33 are provided at the bottom of the base 1. The self-locking universal wheels 33 make the entire device easy to move and can be quickly deployed to the location that needs to be monitored. The power cord of the photochemical sensor 29 is connected to the power interface provided by the control box 6, and ensure that the voltage and current of the power supply meet the specifications of the sensor. The signal line of the photochemical sensor 29 is connected to the corresponding input port of the control box 6.
[0026] Working principle: When using the device, first move the device to a suitable position, then manually adjust the rotation angle of the universal joint 11, so that the rotation angle of the telescopic pipe 12 can be adjusted, and then the electric push rod 14 can be started, and the electric push rod 14 can push the fixed sleeve 15 to move, so that the telescopic end of the telescopic pipe 12 can be driven to be in an extended state; Then the motor 7 can be started, and the motor 7 can drive the output end to rotate, so that the impeller inside the pump body 8 rotates rapidly. When the internal impeller rotates, it makes the gas gain kinetic energy and pushes it to the pump outlet. The pressure at the center of the impeller decreases, forming a negative pressure, thereby sucking in the gas, and the gas can enter the device tank 4 and can be discharged through multiple outlets outside the gas outlet cover 10, and then can be sensed by multiple photochemical sensors 29; When the motor 7 drives the output end to rotate, it can drive the first bevel gear 16 to rotate continuously, thereby driving the second bevel gear 17 and the fixed shaft 18 to rotate continuously, thereby driving the driving wheel 19 to rotate, and the driving wheel 19 can drive the driven wheel 20, the rotating shaft 21 and the rotating rod 22 to rotate continuously through the anti-slip conveyor belt, and the rotating gear 24 can drive the connecting shaft 23 to rotate continuously while rotating outside the gear ring seat 26, so that the connecting shaft 23 drives the rotating gear 24 and the cleaning brush 25 to move in a circle around the rotating shaft 21, and the rotating gear 24 can drive the connecting shaft 23 and the cleaning brush 25 to rotate, so that the outer surfaces of multiple photochemical sensors 29 can be cleaned, and the air can be discharged into the water tank 32 through the outlet pipe 31 after detection; Since ammonia is extremely soluble in water, the water inside the water tank 32 can be subsequently heated so that the ammonia can be discharged and processed separately.
[0027] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
