[0002] Mercury pollution has become a global issue. Mercury is a toxic heavy metal that exists in the environment in three valence states (Hg0, Hg1+, and Hg2+). It is persistent, has long-range mobility, and is bioaccumulative. Emissions primarily come from coal-fired power plants, industrial boilers, waste combustion, and some industrial processes. Due to its toxicity, persistence, and bioaccumulation, Hg pollution among heavy metals is receiving increasing attention. Analyzers in existing monitoring systems, which continuously monitor mercury levels in real-time from pollutant emissions such as coal-fired boilers and waste incinerator flue gases, are calibrated using standard mercury vapor to ensure accuracy.

[0003] Existing standard mercury vapor generators generally obtain mercury vapor of different concentrations by controlling the temperature of a mercury permeation tube. For example, a generator for producing elemental mercury standard gas disclosed in a Chinese patent (Announcement No.: CN105300760B) obtains elemental mercury standard gas of a certain concentration by controlling the carrier gas flow rate and the temperature of a water bath. In actual implementation, due to the lag in operating air pressure changes and temperature regulation, the output mercury vapor concentration is difficult to control, which is not conducive to subsequent calibration work. At the same time, it has no exhaust gas treatment device, which makes it easy for operators to come into contact with mercury vapor, which can easily cause damage to the operator's health.

Detailed description will be given below with reference to the accompanying drawings.

[0031] Please see the attached Figure 2 To the attached Figure 6 In this embodiment, the gas supply mechanism 1 is provided with a low-range output end 11 and a high-range output end 12 for adjusting the mercury vapor concentration through flow regulation. In specific implementation, an electronic pressure photometer control module 45 and a sonic orifice can be used to perform low-range output of the dilution gas, which facilitates control and provides stable flow output.

In specific implementation, the air path assembly can be configured to consist of a solenoid valve and an inerting tube. Each component is connected through the inerting tube, and the opening and closing control of the gas path between each component is controlled by the solenoid valve.

[0037] Example 2:

[0038] Please see the attached Figure 1This embodiment provides a new type of high-precision mercury generating device. The same points as those in the first embodiment will not be described in detail. The differences will be described in detail below with reference to the accompanying drawings.

[0039] Please see the attached Figure 2 To the attached Figure 6 In this embodiment, the concentration detection mechanism 4 includes a gas power device 41, a detection gas chamber 42, a light source assembly 43, a detection assembly 44 and a photometer control module 45.

The light emitting part of the light source assembly 43 is arranged inside the light source emitting part 47 and is connected to the cavity of the detection gas chamber 42. The detection part of the detection assembly 44 is arranged inside the light source receiving part 48 and is connected to the cavity. The temperature adjustment end of the first temperature adjustment mechanism 49 is arranged inside the light source emitting part 47. By adjusting the temperature of the mercury vapor in the concentration detection mechanism 4 to a preset standard temperature, such as the calibration temperature set when calibrating the concentration detection mechanism 4, the detection error is further reduced and the accuracy of the output mercury vapor concentration is improved.

[0042] When this embodiment is working, it is possible to detect the concentration of mercury vapor. At the same time, the first temperature adjustment mechanism 49 is used to adjust the temperature of the mercury vapor in the concentration detection mechanism 4 to a preset standard temperature, so that the detection environment of the concentration detection mechanism 4 can be maintained in a standard detection environment for a long time, which can further improve the accuracy of concentration detection.

[0048] S3: The pure mercury vapor generated by the mercury permeation mechanism 2 and the dilution gas outputted from the high-range output terminal 12 of the gas supply mechanism 1 are introduced into the mercury vapor output mechanism 3 for dilution. The pure mercury vapor is diluted by adjusting the output power of the high-range output terminal 12 of the gas supply mechanism 1.

[0049] S4: The diluted mercury vapor is passed into the concentration detection mechanism 4 for concentration detection, and the concentration information is fed back to the gas supply mechanism 1 to control the output power of the high-range output terminal 12 of the gas supply mechanism 1.

[0051] In step S4, the following steps are also included: adjusting the working temperature of the concentration detection mechanism 4 during concentration detection to a preset standard temperature.

[0052] In a specific implementation, step S2 further includes the following steps: balancing the internal pressure of the high-precision mercury generating device by purifying the pure mercury vapor generated by the diversion part and then discharging it.
