[0014] In the preferred embodiment of the steam generating device described above, multiple sets of semiconductor cooling chips are provided, and the multiple sets of semiconductor cooling chips are evenly distributed on the surface of the conductor block.

[0015] In the preferred embodiment of the steam generating device described above, the humidification device is configured as a humidification container containing a humidifying liquid. The humidification port is located at the top of the humidification container. The steam generating device also includes a dry gas pipe, the inlet of which is connected to a dry gas source, and the outlet of which extends through the humidification port to below the surface of the humidifying liquid, so that the dry gas and the humidifying liquid are in full contact. Furthermore, / or the steam generating device also includes a temperature sensor installed on the condensing device. And / or the steam generating device also includes a heating component fixedly connected to the humidification device.

[0016] In the preferred embodiment of the steam generating device described above, the heating component covers the bottom of the humidification device, and the heating component includes an electric heating element and insulation cotton.

[0017] With the above technical solution adopted, the steam generating equipment of this utility model includes a humidification device, a condensation device, and a gas generating pipe. The humidification device is connected to a dry gas source to introduce dry gas into the humidification device. The humidification device contains humidifying liquid and is equipped with a moisture outlet to convert dry gas into moisture and discharge it from the moisture outlet. The condensation device is equipped with a condensation chamber. The inlet of the condensation chamber is connected to the moisture outlet, and the outlet of the condensation chamber is connected to the gas generating pipe to condense the moisture and discharge it through the gas generating pipe. The condensate generated in the condensation chamber is then returned to the humidification device. With this configuration, during the condensation of moisture through the condensation device, the condensate condensed in the condensation chamber can flow back to the humidification device, eliminating the need for periodic drainage. This achieves the recycling of the condensate, simplifies the operation and maintenance process, and saves water.

[0018] Furthermore, the condensation device of this utility model includes a conductor block and a refrigeration component fixedly connected. The condensation chamber is disposed within the conductor block, the air inlet is located at the bottom of the condensation chamber, and the air outlet is located at the top of the condensation chamber. The humidification device is inserted into the bottom of the conductor block, and the humidification port is located at the top of the humidification device. The refrigeration component can cool the conductor block. This arrangement integrates the humidification device and the condensation device into one unit, improving the integration of the steam generating equipment, simplifying the equipment structure, and reducing the space occupied. Furthermore, it allows the condensed liquid to automatically flow back into the humidification device under the influence of gravity.

[0019] Furthermore, the condensation device of this invention also includes a condensation screen, which is installed inside the condensation chamber. This arrangement ensures, on the one hand, the permeability of moisture and the contact area between moisture and the condensation screen, thus improving the condensation effect; on the other hand, it facilitates the collection and reflux of condensed liquid.

[0020] Furthermore, the condensation device of this invention also includes an indicator container, which is installed inside the conductor block and connected to the air outlet to guide the condensed moisture into the indicator container. The indicator container is provided with a vent, which is connected to the gas generation pipe. This arrangement maintains a low-temperature environment inside the indicator container, allowing the condensation effect of the condensing mesh to be determined by whether liquid droplets are generated inside the indicator container as the condensed moisture passes through.

[0021] Furthermore, the vent of this invention is located at the top of the indicating container, and the steam generating device also includes a connecting pipe. The inlet end of the connecting pipe is connected to the outlet end, and the outlet end of the connecting pipe extends to the bottom of the indicating container through the vent. This design simplifies the structure of the indicating container and allows moisture to be directly introduced to the bottom of the indicating container and then rise along the inner wall, increasing the flow path of the moisture within the container and enabling more complete condensation.

[0022] Furthermore, the conductor block of this invention is provided with a vertical through hole, into which the indicating container is inserted; and / or the bottom of the indicating container is exposed outside the conductor block. With this design, on the one hand, the indicating container is integrated into the condensing device, allowing the steam generating equipment to have an indicating function without increasing the device's size and reducing space occupation; on the other hand, it facilitates quick assembly and disassembly of the indicating container; and thirdly, it allows users to easily observe the condensed liquid inside the indicating container.

[0023] Furthermore, the cooling component is configured as a semiconductor cooling chip. This configuration, compared to a water bath temperature control component, results in several advantages: firstly, the cooling component is smaller and more integrated; secondly, it simplifies use and maintenance, eliminating the need for regular coolant additions and replacements and eliminating the risk of coolant leakage; and thirdly, it provides stable temperature control performance.

[0024] Furthermore, this invention features multiple sets of semiconductor cooling chips, evenly distributed on the surface of the conductor block. This arrangement achieves balanced cooling of the conductor block and the condenser mesh, ensuring effective condensation.

[0025] Furthermore, the humidification device of this invention is configured as a humidification container containing humidifying liquid. A moisture inlet is located at the top of the humidification container. The steam generator also includes a dry gas pipe, with its inlet connected to a dry gas source and its outlet extending below the surface of the humidifying liquid through the moisture inlet, ensuring sufficient contact between the dry gas and the humidifying liquid. Alternatively, the steam generator may also include a temperature sensor mounted on a condenser. Furthermore, the steam generator may also include a heating component fixedly connected to the humidification device. This configuration makes the humidification device simple in structure and easy to implement.

[0031] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] It should be noted that in the description of this utility model, terms such as "inner", "outer", "upper", "lower", "top", and "bottom" that indicate direction or positional relationship are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0033] Furthermore, it should be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] As mentioned in the background section, existing steam generators require periodic discharge of condensate (water, ethanol, etc.) generated during the gas condensation process, increasing the workload of operators. This invention provides a steam generator that integrates a humidifier and steam piping into the condenser, and uses a semiconductor cooling chip as the refrigeration component. This reduces the size of the steam generator, saving installation space. Furthermore, by installing the humidifier at the bottom of the condenser, the condensate generated in the condenser can flow back into the humidifier, achieving condensate recovery and utilization, and simplifying the use and maintenance process.

[0035] Specifically, steam generators can be used with various analytical instruments to provide experimental gases with specific parameters to the instruments. For example, in a physical adsorption apparatus, a quantitative amount of adsorbed gas (such as nitrogen or air) is introduced into a sample tube, and the changes in gas parameters before and after adsorption are measured to analyze the properties of different materials.

[0036] During experiments, to ensure stable and controllable gas flow rate and RH (relative humidity), the dry gas is typically humidified first. This involves mixing a certain amount of liquid vapor into the dry gas to form moist gas. The moist gas is then condensed and filtered to obtain a stable airflow with the target humidity, thus meeting various experimental requirements. The water vapor content in the airflow is stable and quantifiable, and its value can be calculated from the saturated vapor pressure at the target temperature.

[0037] Preferably, such as Figure 1 As shown, the steam generating equipment of this utility model includes a dry gas source, a humidification device, a condensation device, and a gas generating pipe 3. The dry gas source is usually set as an air compressor, gas cylinder or gas tank, etc., for storing dry gas. The type of gas depends on the experimental requirements and can be clean, dry air or nitrogen, etc.

[0038] The humidifier is connected to a dry air source and can introduce dry air into the humidifier. The humidifier contains a humidifying liquid 11, which can be a volatile liquid such as water or ethanol, to humidify the flowing dry air to form moisture. The humidifier also includes a moisture port 12 connected to the air inlet 212 of the condenser, so that moisture can enter the condenser through the moisture port 12.

[0039] The outlet 213 of the condenser is connected to the gas generation pipe 3, and the internal temperature of the condenser is lower than that of the humidifier. This causes the moisture to condense as it flows through the condenser. During the condensation process, the liquid vapor in the moisture condenses into liquid. By adjusting the temperature of the condenser, the amount of liquid vapor condensed in the moisture can be controlled, thereby adjusting the RH value of the moisture to obtain the target moisture required for the experiment. The target moisture is finally sent to the analyzer for experiment through the gas generation pipe 3.

[0040] Preferably, such as Figure 1 As shown, the condensation device of this application is set at the top of the humidification device, and the air inlet 212 of the condensation device is higher than the humidification port 12, so that the condensate generated in the condensation device can automatically flow back to the humidification device under the action of gravity, without the need for manual drainage by the operator, realizing automatic recovery and utilization of condensate, simplifying the operation and maintenance process of the equipment, saving water, organic solvents and other liquids, and reducing harmful solvent waste gas generated in the experiment.

[0041] In addition, in order to improve the integration of steam generating equipment and reduce the size and space occupied by the equipment, this application integrates the humidification device, the condensation device and various ventilation pipelines into one unit.

[0042] Preferably, such as Figure 1As shown, the condensation device of this utility model includes a conductor block 21 and a refrigeration component 22 fixedly connected. A condensation chamber 211 is provided inside the conductor block 21. An air inlet 212 is located at the bottom of the condensation chamber 211. The top of a humidification device is inserted into the bottom of the conductor block 21, and a moisture outlet 12 is located at the top of the humidification device to introduce moisture into the condensation chamber 211 from bottom to top. An air outlet 213 is located at the top of the condensation chamber 211 so that moisture can pass through the condensation chamber 211 from bottom to top and be fully condensed in the condensation chamber 211. Finally, the moisture that meets the experimental requirements is sent to the analyzer through the gas generation pipe 3. The refrigeration component 22 is fixedly connected to the conductor block 21 and can transfer cold energy to the conductor block 21 so that the conductor block 21 and the condensation chamber 211 reach the required condensation temperature.

[0043] By inserting the humidification device into the bottom of the conductor block 21, the integration of the steam generating equipment is improved, the equipment structure is simplified, and the space occupied by the equipment is reduced compared to the separate structure.

[0044] More preferably, the condensation device also includes a condensation screen 23 installed in the condensation chamber 211. The condensation screen 23 is positioned above the moisture inlet 12 and fixedly connected to the inner wall of the condensation chamber 211. Both the conductor block 21 and the condensation screen 23 are made of metal materials that are easy to conduct heat, not easy to rust, and not corroded, such as stainless steel or titanium alloy, to ensure good thermal conductivity, thereby enabling the condensation chamber 211 and the condensation screen 23 to maintain a low temperature. The condensation screen 23 can be in the form of a filter screen, a sintered filter element, or a multi-layer sheet. The mesh structure inside the condensation screen 23 can ensure the passage of moisture and allow sufficient contact and heat exchange between the moisture and the condensation screen 23, improving the condensation effect. It also facilitates the downward flow of the condensed liquid condensed on the condensation screen 23, realizing the recovery of the condensed liquid.

[0045] In practical applications, those skilled in the art can flexibly configure the structure and humidification method of the humidification device. For example, the humidification device can be configured as a humidification container 1 (such as a glass test tube), in which a humidifying liquid 11 is contained. The type of humidifying liquid 11 can be determined according to experimental requirements, such as water or other volatile liquids. The humidification port 12 is located at the top of the humidification container 1. The top of the humidification container 1 is inserted into the conductor block 21 and supports flexible disassembly and assembly to facilitate the filling and replacement of the internal humidifying liquid 11.

[0046] The steam generating device also includes a dry gas pipe 5 that connects the dry gas source and the humidification container 1. The inlet end of the dry gas pipe 5 is connected to the dry gas source, and the outlet end of the dry gas pipe 5 extends through the humidification port 12 to below the liquid surface of the humidification liquid 11, so that the dry gas is directly introduced into the humidification liquid 11 to form bubbles. After the bubbles pass through the humidification liquid 11, they mix with the steam of the humidification liquid 11 and the droplets when the bubbles burst to form moisture.

[0047] Alternatively, a spray device can be installed along the dry gas transport path to convert the dry gas into humid gas by spraying liquid onto it. This case does not specify the specific structure or humidification method of the humidification device, as long as it can humidify the dry gas.

[0048] In order to monitor the condensation effect of condenser 23 on moisture in real time, such as Figure 1 As shown, the condensation device of this application also includes an indicator container 24, which is fixedly installed inside the conductor block 21 to maintain the same temperature as the conductor block 21. The indicator container 24 is disposed between the condensation chamber 211 and the gas generation pipe 3, and is connected to the gas outlet 213 to guide the condensed moisture into the indicator container 24. The indicator container 24 is provided with a vent 241, which is connected to the gas generation pipe 3. When the condensed moisture passes through the indicator container 24, the condensation effect of the moisture in the condensation net 23 can be judged by observing whether droplets form in the indicator container 24. If droplets form in the indicator container 24, it indicates that the condensation effect of the condensation net 23 is poor, and the condensation device needs to be checked.

[0049] Preferably, the conductor block 21 is also provided with a vertical through hole, the indicator container 24 is inserted into the vertical through hole, the vent 241 is provided at the top of the indicator container 24, the steam generating device also includes a connecting pipe 4, the inlet end of the connecting pipe 4 is connected to the outlet 213, the outlet end of the connecting pipe 4 extends to the bottom of the indicator container 24 through the vent 241, and the gas generating pipe 3 is connected to the vent 241.

[0050] This allows the condensed moisture to be directly introduced into the bottom of the indicator container 24, and then the moisture flows upward along the indicator container 24. During the process of contacting the inner wall of the indicator container 24, if the condensation effect of the condenser mesh 23 is not good, the moisture content in the moisture will be too high or there will be small droplets, which will then condense again into droplets on the inner wall of the indicator container 24. The droplets will eventually fall naturally and gather at the bottom of the indicator container 24. Therefore, if droplets are found to form at the bottom of the indicator container 24, it indicates that the condenser is malfunctioning.

[0051] The indicator container 24 is preferably a glass test tube. When the indicator container 24 is inserted into the vertical through hole of the conductor block 21, the bottom of the indicator container 24 is preferably exposed outside the vertical through hole to facilitate observation by the operator.

[0052] By integrating the indicator container 24 into the condensing device, the steam generating equipment can have the function of indicating the condensation effect without increasing the size of the equipment, thus improving the integration of the equipment.

[0053] Regarding the cooling component 22, such as Figure 1As shown, the present invention is preferably configured as a semiconductor cooling chip, which is used for temperature control. Compared with the traditional circulating water bath temperature control structure, on the one hand, the cooling component 22 is smaller and more integrated; on the other hand, the use and maintenance of the cooling component 22 is simpler, without the need for regular filling and replacement of coolant, and there is no risk of coolant leakage; furthermore, the temperature control performance is more stable.

[0054] More preferably, multiple sets of semiconductor cooling chips are provided and evenly distributed on the surface of the conductor block 21 to ensure balanced cooling of the conductor block 21 and the condenser mesh 23 and improve the condensation effect. A heat sink is also provided on the outside of the semiconductor cooling chip to ensure heat dissipation performance.

[0055] Preferably, such as Figure 1 As shown, the steam generating device of this utility model also includes a temperature sensor 6 installed on the conductor block 21. The temperature sensor 6 and the semiconductor cooling chip are both electrically connected to the controller of the device. The controller adjusts the power of the semiconductor cooling chip by collecting the signal of the temperature sensor 6 in real time, so as to cool the condenser to the set target temperature and keep it stable.

[0056] Preferably, such as Figure 1 As shown, the steam generating device also includes a heating component 7 fixedly connected to the humidification device. The heating component 7 can be configured as an electric heating element and insulation cotton. The heating component 7 can heat the humidifying liquid 11 in the humidification container 1 to a higher temperature to generate mixed humid gas with a water vapor content exceeding the experimental requirements, facilitating the RH control of the humidification gas by the condensation device. In one embodiment, the temperature of the humidifying liquid 11 is 30°C, and the internal temperature of the condensation device is 25°C.

[0057] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
