Description

Technical Field

[0001] This utility model relates to the field of mercury analyzer exhaust technology, and in particular to a sample mercury analyzer with an exhaust structure. Background Technology

[0002] Mercury is a chemical element and a toxic substance that poses significant risks to human health and the environment. A mercury analyzer is an instrument used to measure the mercury content in a substance. Its main working principle is based on the absorption characteristics of mercury vapor to light of a specific wavelength. By detecting and analyzing the light, the mercury content is determined. Mercury analyzers have high sensitivity and accuracy, enabling them to quickly and accurately detect trace amounts of mercury in samples. Therefore, mercury analyzers have important applications in environmental monitoring, food safety, and industrial production.

[0003] After a mercury analyzer completes its detection of the mercury content within a substance, the mercury vapor generated during the test needs to be expelled from the analyzer for standardized and harmless treatment. However, existing mercury analyzers generally use activated carbon to adsorb mercury vapor during this process. This adsorption method does not react with the mercury, and there is a possibility that the adsorbed mercury may leak out of the activated carbon again. The leaked mercury vapor can still pose a significant hazard to human health and the environment. Utility Model Content

[0014] Furthermore, the inner wall of the outlet pipe is provided with a sensor for detecting the concentration of mercury vapor inside the outlet pipe.

[0028] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] like Figures 1 to 3 As shown, this embodiment provides a mercury analyzer with an exhaust structure, including: a reaction mechanism 1, an adsorption mechanism 2, and a mercury analyzer 3. The mercury analyzer 3, the adsorption mechanism 2, and the reaction mechanism 1 are connected in sequence, so that the mercury vapor discharged by the mercury analyzer 3 is adsorbed by the adsorption mechanism 2 and oxidized by the reaction mechanism 1 in sequence.

[0030] The beneficial effects of this invention are: the adsorption mechanism is connected to the mercury analyzer, which facilitates the adsorption of mercury vapor discharged from the mercury analyzer first, and the mercury vapor that fails to be adsorbed or escapes is discharged into the reaction mechanism, so that the mercury vapor is oxidized, thus preventing the mercury vapor from escaping to the outside and causing harm to the human body and the environment.

[0031] Preferred, such as Figure 1 and Figure 2As shown, the reaction mechanism 1 includes an air intake device for allowing mercury vapor to enter the reaction chamber 14. The air intake device is slidably connected to the reaction chamber 14, with one end in contact with or separated from the reaction liquid stored in the reaction chamber 14, and the other end connected to the adsorption mechanism 2.

[0032] The advantages of adopting the above-mentioned preferred solution are: the air intake device is slidably connected to the reaction chamber, which is beneficial to the oxidation-reduction reaction between mercury vapor and the reaction liquid when one end of the air intake device comes into contact with the reaction liquid stored in the reaction chamber, thereby oxidizing the mercury vapor and preventing the mercury vapor from escaping into the outside air. At the same time, it is also beneficial to allow the air intake device to slide to separate from the reaction liquid after the mercury vapor has completely undergone the oxidation-reduction reaction with the reaction liquid.

[0033] Preferred, such as Figure 1 and Figure 2 As shown, the air intake device includes: an air intake pipe 11, a telescopic component 12, an electric telescopic rod 13, and an air outlet pipe 15; the two ends of the telescopic component 12 are connected to one end of the air intake pipe 11 and one end of the air outlet pipe 15 respectively; the other end of the air intake pipe 11 is connected to the adsorption mechanism 2; the other end of the air outlet pipe 15 is slidably connected to and connected to the reaction chamber 14; the electric telescopic rod 13 is fixedly installed on the reaction chamber 14, and its output shaft is fixedly connected to the telescopic component 12.

[0034] It should be noted that in this embodiment, the output shaft of the electric telescopic rod 13 is fixedly connected to one end of the telescopic member 12 that connects to the air outlet pipe 15.

[0035] The advantages of adopting the above preferred solution are: the electric telescopic rod facilitates the sliding connection between the gas outlet pipe and the reaction chamber by driving the telescopic component to extend and retract, thereby allowing the other end of the gas outlet pipe to contact or separate from the reaction liquid stored in the reaction chamber.

[0036] Preferred, such as Figure 2 As shown, the telescopic component 12 includes: a first connecting plate 121, a second connecting plate 122, and a telescopic tube 123; the first connecting plate 121 and the second connecting plate 122 are both annular plates, one end of the first connecting plate 121 and one end of the second connecting plate 122 are fixedly and sealed to both ends of the telescopic tube 123, and the other end of the first connecting plate 121 and the other end of the second connecting plate 122 are fixedly and sealed to one end of the air inlet pipe 11 and one end of the air outlet pipe 15, so that the air inlet pipe 11, the telescopic tube 123 and the air outlet pipe 15 are connected, and the output shaft of the electric telescopic rod 13 is fixedly connected to the second connecting plate 122.

[0037] The advantages of adopting the above preferred solution are: the first connecting plate and the second connecting plate are conducive to fixing and sealing the telescopic tube with the inlet pipe and the outlet pipe, so that the mercury vapor discharged by the adsorption mechanism passes through the inlet pipe, the telescopic tube and the outlet pipe in sequence, and comes into contact with the reaction liquid stored in the reaction tank to produce an oxidation-reduction reaction.

[0038] Preferably, the inner wall of the vent pipe 15 is provided with a sensor for detecting the concentration of mercury vapor inside the vent pipe 15.

[0039] It should be noted that in this embodiment, a controller is also included. This controller can be the controller built into the mercury analyzer 3, or it can be a separately set controller. If it is a separately set controller, the controller is a microcontroller or a PLC (Programmable Logic Controller). The controller is electrically connected to the sensor, the electric telescopic rod 13, and the mercury analyzer 3. Only when the sensor detects that the mercury vapor concentration in the vent pipe 15 reaches a preset safety value will the controller control the output shaft of the electric telescopic rod 13 to extend, thereby separating the other end of the vent pipe 15 from the reaction liquid stored in the reaction chamber 14. The signal transmission and control between the controller and the sensor, the electric telescopic rod 13, and the mercury analyzer 3 are all existing technologies. The controller controls the output shaft of the electric telescopic rod 13 to retract, so that the other end of the vent pipe 15 comes into contact with the reaction liquid stored in the reaction tank 14. The electric telescopic rod 13 can be selected such that the length of the output shaft of the electric telescopic rod 13 is adapted to the liquid level of the reaction liquid stored in the reaction tank 14. That is, when the output shaft of the electric telescopic rod 13 is fully retracted, the other end of the vent pipe 15 is below the liquid level of the reaction liquid, so that the mercury vapor comes into direct contact with the reaction liquid and undergoes an oxidation-reduction reaction the moment it exits the vent pipe 15. At the same time, when the output shaft of the electric telescopic rod 13 is fully retracted, the position of the sensor on the inner wall of the vent pipe 15 is above the liquid level of the reaction liquid, so as to avoid the reaction liquid affecting the operation of the sensor. As for the liquid level of the reaction liquid stored in the reaction tank 14, a fixed height can be added each time to adapt to the above-mentioned selection requirements for the electric telescopic rod 13; The controller will send a command to the mercury analyzer 3 to discharge mercury vapor when the output shaft of the electric telescopic rod 13 is fully retracted (i.e., the other end of the vent pipe 15 is below the reaction liquid level).

[0040] The advantages of adopting the above-mentioned preferred solution are: it helps to provide a judgment condition for the separation of the gas outlet pipe driven by the electric telescopic rod from the reaction liquid stored in the reaction chamber, and this judgment condition is also the condition for the completion of mercury vapor treatment.

[0041] Preferred, such as Figure 2 As shown, the top of the reaction chamber 14 is provided with a first connecting hole 141. The first connecting hole 141 is a through hole. The gas outlet pipe 15 slides up and down through the first connecting hole 141, and its other end is in contact with or separates from the reaction liquid stored in the reaction chamber 14.

[0042] The advantages of adopting the above preferred solution are: the first connecting hole facilitates the vertical displacement of the gas outlet pipe within the reaction chamber, thereby providing a channel for the other end of the gas outlet pipe to contact or separate from the reaction liquid stored in the reaction chamber.

[0043] Preferably, the reaction solution stored in the reaction tank 14 is a mixed solution of potassium permanganate and dilute sulfuric acid.

[0044] It should be noted that, in this embodiment, the chemical equation for the redox reaction between mercury vapor and a mixed solution of potassium permanganate and dilute sulfuric acid is as follows: 2KMnO4+8H2SO4(dilute)+5Hg=K2SO4+2MnSO4+5HgSO4+8H2O Furthermore, in order to improve the efficiency of the reaction, the reaction solution in the reaction chamber 14 can be heated. However, it should be noted that since the purpose of heating the reaction solution in the reaction chamber 14 is to increase the activation energy required for the reaction, it is necessary to ensure that the solution temperature does not rise to the point that H2SO4 volatilizes or KMnO4 decomposes when heating the reaction solution in the reaction chamber 14. As for the materials of the vent pipe 15 and the reaction chamber 14, materials that do not chemically react with the reaction liquid, such as glass, are selected.

[0045] The advantages of adopting the above preferred solution are: it helps to oxidize mercury vapor into mercury salt solution, thus preventing mercury vapor from escaping into the air and causing harm to the human body and the environment.

[0046] Preferred, such as Figure 2 As shown, the top of the reaction chamber 14 is also provided with a second communication hole 142 for communicating the reaction chamber 14 with the outside world.

[0047] The advantages of adopting the above-mentioned preferred scheme are: it facilitates the connection between the reaction chamber and the outside world, avoids excessive pressure in the reaction chamber that could lead to an explosion, and also provides a channel for the addition and discharge of the reaction liquid.

[0048] Preferred, such as Figure 3As shown, the adsorption mechanism 2 includes: a first connecting pipe 22, a second connecting pipe 23, and an adsorption component 25; one end of the first connecting pipe 22 is fixedly connected to the side wall of the mercury analyzer 3, one end of the adsorption component 25 passes through the first connecting pipe 22 and is connected to the exhaust port of the mercury analyzer 3 for outputting mercury vapor, and its other end is connected to one end of the second connecting pipe 23, and the other end of the second connecting pipe 23 is connected to the reaction mechanism 1.

[0049] It should be noted that in this embodiment, the other end of the second connecting pipe 23 is connected to the side wall of the air intake pipe 11 and is in a sealed connection.

[0050] The advantages of adopting the above preferred scheme are: the adsorption component is conducive to pre-adsorption treatment of mercury vapor discharged from the mercury analyzer, and the first connecting pipe and the second connecting pipe are conducive to connecting the adsorption component with the reaction mechanism and the mercury analyzer.

[0051] Preferred, such as Figure 1 and Figure 3 As shown, the adsorption assembly 25 includes: an adsorption tube 251 with activated carbon inside, a first multi-way valve 252, a first connecting hose 253, a second multi-way valve 254, and a second connecting hose 255; the two ends of the first multi-way valve 252 are connected to one end of the adsorption tube 251 and one end of the first connecting hose 253 respectively; the first connecting hose 253 passes through the first connecting tube 22, and its other end is connected to the exhaust port of the mercury analyzer 3 for outputting mercury vapor; the two ends of the second multi-way valve 254 are connected to the other end of the adsorption tube 251 and one end of the second connecting hose 255 respectively; the other end of the second connecting hose 255 is connected to one end of the second connecting tube 23.

[0052] It should be noted that the number of adsorption tubes 251 is at least one. In this embodiment, the number of adsorption tubes 251 is seven. Accordingly, the end of the first multi-way valve 252 connected to the adsorption tube 251 and the end of the second multi-way valve 254 connected to the adsorption tube 251 have seven connection ports. In this embodiment, since the diameter of the second connecting hose 255 differs significantly from the diameter of the second connecting pipe 23, the end of the second connecting pipe 23 connected to the second connecting hose 255 is tapered. After the second connecting hose 255 is sleeved on the tapered end of the second connecting pipe 23, the second connecting hose 255 and the second connecting pipe 23 can be stably sealed and connected using fasteners such as cable ties and rubber bands. The first multi-way valve 252 and the adsorption tube 251 are connected by a pipeline, as are the second multi-way valve 254 and the adsorption tube 251.

[0053] The advantages of adopting the above-mentioned preferred scheme are: it facilitates the input of mercury vapor discharged from the mercury analyzer into the activated carbon in the adsorption tube for pre-adsorption treatment of the mercury vapor; and the multi-port valve and connecting hose facilitate the participation of multiple adsorption tubes in adsorption, thereby improving the treatment efficiency and effect of mercury vapor.

[0054] Preferred, such as Figure 1 and Figure 3 As shown, the adsorption mechanism 2 also includes two protective shells 21 and a support frame 24. The two protective shells 21 are detachably connected to form a shell structure sleeved on the adsorption assembly 25, the first connecting tube 22 and the second connecting tube 23. The protective shells 21 are placed on the support frame 24.

[0055] The advantages of adopting the above preferred solution are: the protective shell and the support frame help to provide protection and support for the adsorption component, and the two protective shells are detachably connected, which facilitates the replacement of the adsorption component.

[0056] The working process of this embodiment is described below: like Figures 1 to 3 As shown, the output shaft of the electric telescopic rod 13 is first retracted by the controller, so that the vent pipe 15 slides downward in the first connecting hole 141 until the end of the vent pipe 15 is inserted into the reaction liquid in the reaction tank 14. Then, the mercury analyzer 3 discharges mercury vapor. The mercury vapor enters the adsorption tube 251 through the first connecting hose 253, the first multi-way valve 252, and the pipe between the first multi-way valve 252 and the adsorption tube 251. The activated carbon in the adsorption tube 251 adsorbs the mercury vapor. If there is a lot of mercury vapor, the activated carbon in the adsorption tube 251 cannot completely adsorb it. The excess mercury vapor will enter the reaction liquid in the reaction chamber 14 through the pipe between the second multi-way valve 254 and the adsorption tube 251, the second multi-way valve 254, the second connecting hose 255, the second connecting pipe 23, the air inlet pipe 11, the telescopic pipe 123, and the air outlet pipe 15. It will then undergo an oxidation-reduction reaction with the reaction liquid in the reaction chamber 14 to generate a mercury salt solution. When the sensor on the inner wall of the vent pipe 15 detects that the mercury vapor concentration in the vent pipe 15 has reached the preset safety value, the controller controls the output shaft of the electric telescopic rod 13 to extend, so that the vent pipe 15 slides upward in the first connecting hole 141 until the end of the vent pipe 15 separates from the liquid surface in the reaction tank 14.

[0057] Subsequently, the user can remove the vent pipe 15 from the reaction chamber 14 to perform further treatment on the salt solution inside the reaction chamber 14, which will not be described in detail here.
