[0003] In the process of vehicle emissions testing, the traditional method for calibrating analyzers is to generate zero gas using high-purity nitrogen or steel cylinders. This method is costly, complex, time-consuming, and inconvenient for transportation and storage. Zero gas generators can generate pure gas in real time, reducing operating costs. However, most zero gas generators are manual stand-alone units, which cannot meet the needs of modern intelligent operation and maintenance. Utility Model Content

[0004] In view of this, the present invention provides an intelligent zero gas generator and a zero gas generation system to solve the problem that most related zero gas generators are manual single-machine operation modes, which cannot meet the needs of modern intelligent operation and maintenance.

The control unit is used to detect the air parameters of the air compression module, catalytic conversion module, condensation module and drying and purification module and transmit them to the host computer for real-time control via the transmission module.

[0006] Beneficial effects: By controlling the real-time detection of key air parameters and connecting to a host computer via a transmission module, remote and real-time monitoring of the device's operating status is achieved, improving ease of use and management efficiency. Based on the host computer's real-time control capabilities, equipment operating parameters can be adjusted promptly or start / stop operations can be executed, ensuring stable and reliable zero-air output quality, while also providing a data foundation for fault early warning and intelligent operation and maintenance.

[0007] In one optional embodiment, the catalytic conversion module includes a catalytic conversion furnace and a temperature controller, wherein the inlet end of the catalytic conversion furnace is connected to the outlet end of the air compression module, and the temperature controller is connected to the catalytic conversion furnace.

[0008] In one optional embodiment, the condensation module includes a condenser, the inlet of which is connected to the outlet of the catalytic converter, and the condenser is further provided with a drain pneumatic valve.

[0009] Beneficial effects: By controlling the temperature of the catalytic converter using a temperature controller, combined with the control of the drain pneumatic valve in the condenser module, the preheating efficiency of the catalytic converter is ensured, and the catalytic reaction is always carried out within the optimal temperature range. This improves the catalytic conversion efficiency and guarantees the purity of the output gas. The temperature controller also automates the heating process, avoiding the risks of incomplete catalysis due to excessively low temperatures or equipment damage due to excessively high temperatures, thus improving operational reliability and device safety.

The exhaust pneumatic valve is installed on the exhaust pipe between the temperature and humidity sensor and the output pneumatic valve.

[0015] Beneficial effects: The temperature and humidity sensor monitors the temperature and humidity of the final gas flowing through the exhaust pipe in real time and transmits the data to the host computer. The host computer determines whether the final gas is purified to a acceptable level. When the gas is determined to be purified and ready for output, it drives the relay group through the transmission module to open the output pneumatic valve and close the exhaust pneumatic valve, outputting qualified zero gas. When the gas is determined not to be purified to a acceptable level, it drives the relay group through the transmission module to close the output pneumatic valve and open the exhaust pneumatic valve, isolating the exhaust pipeline and discharging waste gas. Through the installation of the temperature and humidity sensor, exhaust pneumatic valve, and output pneumatic valve, automatic and precise control of zero gas output is achieved.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] A zero-gas generator is an intelligent device that uses multi-stage purification technology to remove pollutants from the air and produce pure "zero gas." With the strict implementation of the China VI emission standards, the penetration rate of zero-gas generators in motor vehicle testing institutions is rapidly increasing.

[0024] In the process of vehicle emissions testing, the traditional method for calibrating analyzers is to generate zero gas using high-purity nitrogen or steel cylinders. This method is costly, complex, time-consuming, and inconvenient for transportation and storage. Zero gas generators can generate pure gas in real time, reducing operating costs. However, most zero gas generators are manual stand-alone units, which cannot meet the needs of modern intelligent operation and maintenance.

[0025] To solve the above technical problems, the following will be combined with... Figures 1 to 4 The following describes embodiments of the present invention.

[0026] According to an embodiment of the present invention, an intelligent zero-gas generator is provided, comprising: an air compression module 1, a catalytic conversion module, a condensation module, a drying and purification module 4, and a control unit 6.

[0027] like Figure 1 As shown, the air compression module 1, catalytic conversion module, condensation module, and drying and purification module 4 are connected in series. The air inlet of the air compression module 1 is connected to air, and the air outlet of the air compression module 1 is connected to the air inlet of the catalytic conversion module via an air supply pipeline. The air outlet of the catalytic conversion module is connected to the air inlet of the condensation module via an air supply pipeline, and the air outlet of the condensation module is connected to the air inlet of the drying and purification module 4 via an air supply pipeline. The air outlet of the drying and purification module 4 discharges gas. The control unit 6 is used to detect the air parameters of the air compression module 1, catalytic conversion module, condensation module, and drying and purification module 4. The control unit 6 contains a transmission module 61.

[0028] When air purification is required, ambient air is drawn in by the air compression module 1 and compressed to a predetermined pressure, which can be 0.1-0.15 MPa. The compressed air enters the catalytic conversion module through the air supply pipeline. At a set high temperature, the catalytic conversion module uses a catalyst to convert pollutants in the air into harmless substances. The high-temperature gas then enters the condensation module, where it is rapidly cooled by semiconductor refrigeration. During this process, water vapor in the gas is condensed into liquid water and separated from the gas. The cooled gas, with most of its moisture removed, enters the drying and purification module 4, where it is further dried and purified through the physical adsorption and chemical action of the composite filter element, ultimately producing pure "zero gas".

[0029] Throughout the process, the control unit 6 monitors key parameters of the gas flowing through each module in real time. The monitored data is transmitted to the host computer 7 via the transmission module 61, which can be a WIFI transmission module. The host computer 7 analyzes and records the data, and can run calibration algorithms to send control commands, thereby achieving real-time control of the device.

[0030] This device continuously and stably generates zero gas that meets national standards through the synergistic effect of air compression module 1, catalytic conversion module, condensation module and drying and purification module 4.

[0031] By controlling the control unit 6 to monitor key air parameters in real time and connecting it to the host computer 7 via the transmission module 61, remote and real-time monitoring of the device's operating status is achieved, improving ease of use and management efficiency. Based on the real-time control capabilities of the host computer 7, equipment operating parameters can be adjusted promptly or start / stop operations can be executed, ensuring stable and reliable zero-air output quality, while also providing a data foundation for fault early warning and intelligent operation and maintenance.

[0032] In one embodiment, such as Figure 1 As shown, the catalytic conversion module includes a catalytic conversion furnace 2 and a temperature controller. The inlet of the catalytic conversion furnace 2 is connected to the outlet of the air compression module 1, and the temperature controller is connected to the catalytic conversion furnace 2. The condensation module includes a condenser 3. The inlet of the condenser 3 is connected to the outlet of the catalytic conversion furnace 2, and a drain pneumatic valve is also provided on the condenser 3. The drying and purification assembly 41 includes a first drying and purification tank 411, a second drying and purification tank 412, and a drying tank 413; the first drying and purification tank 411, the second drying and purification tank 412, and the drying tank 413 are connected in series. The molecular sieve assembly 42 includes several molecular sieves 421 connected in series.

[0033] The intelligent zero-gas generator also includes an exhaust pipe 5, which is installed at the outlet end of the molecular sieve assembly 42; an output pneumatic valve 53 is also installed on the exhaust pipe 5 to isolate or connect the exhaust pipe 5.

[0034] The intelligent zero-air generator also includes a temperature and humidity sensor 51 and an exhaust pneumatic valve 52. The temperature and humidity sensor 51 is installed on the exhaust pipe 5 to detect the temperature and humidity of the air inside the exhaust pipe 5; the exhaust pneumatic valve 52 is installed on the exhaust pipe 5 between the temperature and humidity sensor 51 and the output pneumatic valve 53.

[0035] The control unit 6 includes a relay group 62, which is connected to the drain pneumatic valve, the exhaust pneumatic valve 52 and the output pneumatic valve 53. The relay group 62 is used to control the opening and closing of the drain pneumatic valve, the exhaust pneumatic valve 52 and the output pneumatic valve 53.

[0036] Specifically, the catalytic converter 2 is a high-temperature catalytic converter 2, which contains a palladium / platinum catalyst and has a heating function. The temperature controller is electrically connected to the heating structure inside the catalytic converter 2, and also integrates temperature monitoring functionality. Users can set the target heating temperature of the catalytic converter 2 via the temperature controller, with a default heating temperature of 400℃. When the catalytic converter 2 reaches and maintains the set high temperature, pollutants in the compressed air undergo a catalytic oxidation-reduction reaction with the catalyst, being converted into harmless substances.

[0037] Condenser 3 is used to rapidly cool the high-temperature gas from catalytic converter 2. A drain pneumatic valve is installed at the bottom of condenser 3 or at the condensate collection point to open or close the condensate drain channel. The high-temperature gas from the high-temperature catalytic converter 2, after catalytic treatment, enters condenser 3. Condenser 3 absorbs heat from the gas, lowering its temperature. Once the gas temperature drops below a preset temperature, the water vapor it contains is condensed into liquid water and accumulates at the bottom of condenser 3.

[0038] The relay group 62 can control the opening of the drain pneumatic valve to discharge the condensate in the catalytic converter 2 and the condenser 3, as well as the pipeline between them.

[0039] The inlet of the first drying and purification tank 411 is connected to the outlet of the condenser 3 via a gas pipeline. The inlet of the second drying and purification tank 412 is connected to the outlet of the first drying and purification tank 411 via a gas pipeline, and the outlet of the second drying and purification tank 412 is connected to the inlet of the drying tank 413 via a gas pipeline. Inside the first drying and purification tank 411, along the gas transmission direction, are sequentially arranged a moisture-absorbing and color-changing silica gel layer, a separator filter cotton layer, an activated carbon layer, another separator filter cotton layer, and a potassium permanganate alumina layer. Inside the second drying and purification tank 412, along the gas transmission direction, are sequentially arranged a quicklime desiccant layer, a separator filter cotton layer, and a potassium permanganate alumina layer. Inside the drying tank 413, a quicklime desiccant layer is provided.

[0040] The molecular sieve assembly 42 includes two molecular sieves 421 connected in series. Each molecular sieve 421 has an outlet and an inlet. The inlet is directly connected to the outlet of the drying tank 413 and is responsible for deep drying and purification of the gas.

[0041] The working process of the above-mentioned intelligent zero gas generator is as follows: like Figure 3 and Figure 4 As shown, when the intelligent zero gas generator is powered on, the control unit 6 detects the current of the live wire and the neutral wire. If there is a leakage in the equipment circuit, the relay of the equipment power supply line is automatically disconnected to cut off the power to the equipment, and the leakage alarm information is displayed on the host computer 7.

[0042] If there is no leakage, the temperature controller will start working first to preheat, and the temperature controller will control the heating of catalytic conversion furnace 2. During this process, if it is a second start-up, when the entire intelligent zero gas generator stops generating zero gas after a period of time, some high-temperature gas will remain in the pipeline between the condensation module and the catalytic conversion module. During its natural cooling process, condensate will also remain in the pipeline between the condensation module and the catalytic conversion module. Therefore, during the second start-up, the catalytic conversion furnace 2 may occasionally fail to heat to the preset temperature under normal power. If the temperature controller detects that the temperature of the catalytic conversion furnace 2 has not reached the heating temperature set by the temperature controller, it is determined that there is condensate remaining in the pipeline between the condensation module and the catalytic conversion module. The relay controls the opening of the drain pneumatic valve and the closing of the exhaust pneumatic valve 52 and the output pneumatic valve 53 to drain and discharge waste gas from the gas pipe. During this process, the heating structure inside the catalytic conversion furnace 2 continues to heat until the temperature of the catalytic conversion furnace 2 reaches the heating temperature preset by the temperature controller. The relay controls the closing of the drain pneumatic valve, the exhaust pneumatic valve 52 and the output pneumatic valve 53 to prevent untreated air backflow or gas leakage, thus ending the preheating stage.

[0043] The air compression module 1 delivers compressed air to the catalytic converter 2. The temperature controller continuously monitors the internal temperature of the catalytic converter 2 and outputs the monitored parameters to the host computer 7. The host computer 7 compares the parameters with the preset target temperature. Based on the comparison result, the host computer 7 controls the temperature controller to output a control signal to control the power of the heating elements inside the catalytic converter 2 so that the temperature inside the furnace reaches and stabilizes at the preset working temperature.

[0044] The catalyzed high-temperature gas enters condenser 3, which cools the gas to room temperature. During this process, condensate is generated. Control unit 6 can control the intermittent opening and closing of the drain pneumatic valve via a relay to drain the condensate.

[0045] The gas output from condenser 3 enters the drying and purification assembly 41, passing through the moisture-absorbing and color-changing silica gel layer, the separator filter cotton layer, the activated carbon layer, the separator filter cotton layer, and the potassium permanganate alumina layer in the first drying and purification tank 411. It then passes through the quicklime desiccant layer, the separator filter cotton layer, and the potassium permanganate alumina layer in the second drying and purification tank 412, and finally enters the quicklime desiccant layer in the drying tank 413. In the drying and purification assembly 41, most of the residual moisture and specific chemical contaminants are removed.

[0046] Subsequently, the gas flows into the two molecular sieves 421 within the molecular sieve assembly 42. The molecular sieves 421, utilizing their regular microporous structure, selectively adsorb trace amounts of water molecules and small molecule contaminants from the gas, achieving deep purification and ultimately outputting high-purity zero gas, which is then discharged from the exhaust pipe 5.

[0047] Control unit 6 controls the opening and closing of the drain pneumatic valve according to a preset program or sensor signals. When drainage is required, relay group 62 drives the drain pneumatic valve to open, draining the accumulated liquid water from the system; after drainage is completed, the valve closes to prevent untreated air backflow or gas leakage.

[0048] Temperature control of catalytic converter 2, combined with control of the drain pneumatic valve in the condenser module, ensures the preheating efficiency of catalytic converter 2 and guarantees that the catalytic reaction always proceeds within the optimal temperature range. This improves catalytic conversion efficiency and ensures the purity of the output gas. The temperature controller also automates the heating process, avoiding the risks of incomplete catalysis due to excessively low temperatures or equipment damage due to excessively high temperatures, thus improving operational reliability and device safety.

[0049] Temperature and humidity sensor 51 monitors the temperature and humidity of the final gas flowing through exhaust pipe 5 in real time and transmits the data to host computer 7. Host computer 7 judges whether the final gas is purified and qualified. When it is judged that the gas has been purified and qualified and needs to be output, it drives relay group 62 through transmission module 61 to open output pneumatic valve 53 and close exhaust pneumatic valve 52, and output qualified zero gas.

[0050] When the gas is determined to be unpurified, the transmission module 61 drives the relay group 62 to close the output pneumatic valve 53 and open the exhaust pneumatic valve 52, thus disconnecting the exhaust pipe 5 and discharging the waste gas.

[0051] Automatic and precise control of zero air output is achieved through the set temperature and humidity sensor 51, exhaust pneumatic valve 52 and output pneumatic valve 53.

[0052] According to an embodiment of the present invention, another aspect provides a zero gas generation system, including a host computer 7 and the aforementioned intelligent zero gas generation device, wherein the host computer 7 is connected to the transmission module 61 and the relay group 62 in the intelligent zero gas generation device.

[0053] like Figure 2 As shown, the host computer 7 specifically includes a gas calibration algorithm cloud platform 71 and a mobile APP 72. The cloud platform is deployed on a server and is responsible for data storage, analysis, and running of calibration algorithms; the mobile APP 72 serves as the user interface, providing remote monitoring and control functions.

[0054] The host computer 7 establishes a connection with the device through the device's transmission module 61; at the same time, the host computer 7 can send instructions to the control unit 6 through the transmission module 61 to indirectly control the operation of the relay group 62.

[0055] The intelligent zero-gas generator's temperature controller and temperature and humidity sensor 51 collect real-time data on equipment status and gas parameters, and transmit this data to the host computer 7 via transmission module 61. Users can remotely view this information in real-time via a mobile app 72. Users can also set parameters or send control commands through the mobile app 72. These commands are sent to the control unit 6 via the cloud platform and transmission module 61. After parsing the commands, the control unit 6 drives the relay group 62 to perform the corresponding operations.

[0056] The above settings enable remote real-time monitoring and parameter setting, ensuring stable and reliable zero gas quality and safe and intelligent equipment operation.

[0057] In one embodiment, based on the statistical records of the operating time of each device, when the set maintenance time is reached, the mobile APP 72 will proactively push maintenance suggestions and manuals to remind users to disconnect the power in time, replace accessories such as air pipes and filter materials, and check the circuit for maintenance operations.

[0058] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
