Description

Technical Field

[0001] The utility model relates to the technical field of calibration of environmental protection ozone monitors, in particular to a calibration device for environmental protection ozone monitors. Background Art

[0002] An ozone monitor is a device specifically used to measure and monitor the ozone concentration in the air, which can monitor the air quality in real time. However, during the use of the ozone monitor, there may be errors in the measurement results. Therefore, it is necessary to calibrate the ozone monitor frequently to ensure its stable performance and reliable measurement results.

[0003] Application No. 202220217644.6 discloses a calibration device for an environmental protection ozone monitoring instrument, which includes a zero gas generator and an ozone generator. The gas outlet end of the zero gas generator is respectively connected to a plurality of first accommodation boxes and a second accommodation box through a first air duct, and the gas outlet end of the ozone generator is connected to the adjacent first accommodation box and the second accommodation box through a second air duct. An ozone analyzer is installed on the upper side of the first accommodation box. With the mutual cooperation of various parts in the proposed calibration device, through the setting of the exhaust fan, the internal gas can be actively sucked, that is, the speed of discharging the mixed gas and zero gas from the device is increased. The setting of the ozone analyzer has a lower price compared with the traditional ozone calibrator. And the setting of the flowmeter enables personnel to accurately control the flow rate of zero gas and ozone gas when inputting into the first accommodation box and the second accommodation box during the calibration process.

[0004] The above-mentioned solution has deficiencies during use. After the zero gas and ozone generated by the zero gas generator and the ozone generator enter the first accommodation box and the second accommodation box, they cannot be quickly and evenly mixed, and it is impossible to ensure that the degree of uniform mixing between the zero gas and ozone in the first accommodation box and the second accommodation box is the same. Since the ozone analyzer and the ozone detection instrument respectively detect the inside of the first accommodation box and the second accommodation box, it is impossible to ensure the accuracy of the detection results when analyzing the mixed gas, which will have a certain impact on the calibration of the ozone monitoring instrument. Therefore, we provide a calibration device for environmental protection ozone monitors. Summary of the Utility Model

[0026] A stabilizing plate 205 is fixedly connected to the front surface of the ozone generator 201 and the back surface of the zero-air generator 202. The stabilizing plate 205 can be used to connect the ozone generator 201 and the zero-air generator 202, so as to ensure the firmness between them and prevent the connecting pipe 203 from being bent.

[0027] An ozone analyzer 3 is installed on the upper surface of the mixing tank 1. A discharge pipe 4 is fixedly connected to the upper surface of the mixing tank 1.
