Description

Technical Field

[0001] This application relates to the field of microbial culture equipment technology, and more specifically, to a palladium catalyst dehydration and reduction device and an anaerobic workstation. Background Technology

[0002] Anaerobic workstations are commonly used equipment in microbiology experiments, providing an anaerobic environment for the inoculation, classification, and cultivation of anaerobic microorganisms. The anaerobic environment is typically created by replacing oxygen-containing gas within the chamber with a mixed gas, combined with cold catalysis. This involves passing the gas through a deoxygenating catalyst containing a palladium catalyst. The palladium catalyst reacts with oxygen and hydrogen to produce water, consuming the oxygen and creating the anaerobic environment. This, along with a gas supply system and a temperature and humidity control system, provides a suitable growth environment for anaerobic microorganisms. However, to reuse the palladium catalyst, operators place the deoxygenating catalyst inside the anaerobic chamber, remove it after use, heat it to remove moisture, and then return it before use. This method is time-consuming and labor-intensive, impacting work efficiency. Utility Model Content

[0003] The purpose of this application is to provide a palladium catalyst dehydration and reduction device and an anaerobic workstation, which aims to solve the problem that the dehydration and reduction of palladium catalyst in related technologies requires manual operation, which is time-consuming, labor-intensive, and affects work efficiency.

[0004] In a first aspect, this application provides a palladium catalyst dehydration and reduction device, comprising: an internal circulation duct disposed above the top plate of an incubator; the internal circulation duct being interconnected with the internal space of the incubator; a catalytic chamber and an internal circulation fan disposed within the internal circulation duct; wherein the outlet of the catalytic chamber is connected to the inlet of the internal circulation fan; a heater, a catalytic chamber damper, and a palladium catalyst are disposed within the catalytic chamber; the heater is used to heat the air inside the incubator; the catalytic chamber damper is used to control the opening and closing state of the palladium catalyst; and the internal circulation fan is used to draw air from the incubator into the internal circulation duct.

[0005] In the above implementation process, a palladium catalyst dehydration and reduction device is provided. This device includes an internal circulation duct located above the top plate of an incubator, which is connected to the internal space of the incubator. The internal circulation duct contains a catalytic chamber and an internal circulation fan. The catalytic chamber contains a heater, a catalytic chamber damper, and a palladium catalyst. Under the action of the internal circulation fan, air from the incubator is drawn into the internal circulation duct, heated by the heater, and then flows through the catalytic chamber damper past the palladium catalyst. The air then enters the internal circulation fan and returns to the incubator from the fan's outlet. With the continuous operation of the internal circulation fan, hot air continuously flows past the palladium catalyst, thereby achieving automatic dehydration and reduction of the palladium catalyst. This eliminates the need for manual operation, saving labor costs and improving work efficiency.

[0006] Furthermore, in some embodiments, the internal circulation air duct is connected to the internal space of the incubator via an exhaust pipe; one end of the exhaust pipe is connected to the air outlet of the internal circulation fan, and the other end is located at the bottom of the incubator.

[0007] In the above implementation process, an exhaust pipe is set between the internal circulation air duct and the incubator. The air generated by the air outlet of the internal circulation fan flows to the bottom of the incubator through the exhaust pipe. In this way, through the continuous circulation of the internal circulation fan, the hot air can be evenly distributed inside the incubator, thereby making the temperature inside the incubator uniform and avoiding excessive local temperature.

[0008] Furthermore, in some embodiments, the incubator further includes: an exhaust damper disposed in the top plate of the incubator; an exhaust fan disposed above the top plate of the incubator; the air inlet of the exhaust fan being connected to the exhaust damper; and the exhaust fan being used to exhaust air from the incubator to the outside of the incubator through the exhaust damper.

[0009] In the above implementation process, an exhaust damper is installed on the top plate of the incubator. This exhaust damper is connected to the air inlet of the exhaust fan. In this way, during ventilation, the exhaust damper and the exhaust fan can be opened to allow the high humidity air inside the incubator to be discharged from the outside of the incubator, thereby ensuring that the humidity inside the incubator is within a suitable range.

[0010] Furthermore, in some embodiments, a humidity sensor is also included, disposed inside the incubator, for detecting the humidity inside the incubator.

[0011] In the above process, a humidity sensor is installed in the incubator. If the humidity detected by the humidity sensor no longer increases during the dehydration and reduction process, it indicates that there is no moisture inside the palladium catalyst. In this way, the operator can accurately grasp the dehydration and reduction progress of the palladium catalyst.

[0012] Furthermore, in some embodiments, it further includes: a display control system, including a display screen and a controller; the display screen is used to display the detection results of the humidity sensor; the controller is used to control the switching of the heater, the catalytic chamber damper, and the internal circulation fan.

[0013] In the above implementation process, a display and control system is added to the palladium catalyst dehydration and reduction unit to introduce display and control functions and enhance the intelligence of the equipment.

[0014] Furthermore, in some embodiments, the heater is a PTC heating element.

[0015] In the above process, using a PTC heating element to heat and dehydrate the palladium catalyst can improve the overall performance of the device.

[0016] Furthermore, in some embodiments, the internal circulation fan is a centrifugal fan.

[0017] In the above process, using a centrifugal fan to drive the air to circulate between the incubator and the internal circulation duct can improve the energy efficiency of the entire system.

[0018] Secondly, this application provides an anaerobic workstation, including an incubator and a palladium catalyst dehydration and reduction device as described in any one of the first aspects.

[0019] Other features and advantages disclosed in this application will be set forth in the following description, or some features and advantages may be inferred from the description or determined without doubt, or may be learned by practicing the above-described technology disclosed in this application.

[0030] As described in the background section, the dehydration and reduction of palladium catalysts in related technologies requires manual operation, which is time-consuming, labor-intensive, and affects work efficiency. Therefore, this application provides a palladium catalyst dehydration and reduction apparatus to solve the aforementioned problems.

[0031] The embodiments of this application will be described below:

[0032] like Figure 1 As shown, Figure 1 This is a schematic diagram of a palladium catalyst dehydration and reduction device provided in an embodiment of this application. The arrows in the diagram indicate the direction of airflow. The palladium catalyst dehydration and reduction device includes: an internal circulation duct 11, disposed above the top plate of the incubator 10; the internal circulation duct 11 is interconnected with the internal space of the incubator 10; a catalytic chamber 12 and an internal circulation fan 13 are disposed in the internal circulation duct 11; wherein the air outlet of the catalytic chamber 12 is connected to the air inlet of the internal circulation fan 13; a heater 14, a catalytic chamber damper 15, and a palladium catalyst 16 are disposed in the catalytic chamber 12; the heater 14 is used to heat the air inside the incubator 10; the catalytic chamber damper 15 is used to control the opening and closing state of the palladium catalyst 16; and the internal circulation fan 13 is used to draw air from the incubator 10 into the internal circulation duct 11.

[0033] The aforementioned palladium catalyst dehydration and reduction device can be applied to various microbial culture and experimental instruments that use palladium catalysts as deoxygenation catalysts. Taking an anaerobic workstation as an example, an anaerobic workstation is a commonly used piece of equipment in microbial experiments, mainly used for the cultivation and research of microorganisms in an anaerobic environment. The incubator is the core component of the anaerobic workstation; it serves as the anaerobic bacteria culture chamber and also as the operating room for the operator to perform experimental operations. During ventilation, the palladium catalyst reacts with oxygen and hydrogen to generate water, consuming oxygen and creating an anaerobic environment. The palladium catalyst material is mainly alumina, which absorbs the water generated during the catalytic process. Before use, the internal moisture of the palladium catalyst needs to be removed to reduce the palladium catalyst. The palladium catalyst dehydration and reduction device provided in this embodiment can achieve automatic dehydration and reduction of the palladium catalyst, saving labor costs and improving work efficiency.

[0034] Specifically, in the aforementioned palladium catalyst dehydration and reduction device, the internal circulation duct is an air duct located above the top plate of the incubator. The shape of this duct can be customized according to the size and shape of the incubator. The duct can be made of corrosion-resistant, high-temperature-resistant, and easy-to-maintain materials, such as stainless steel, aluminum alloy, or special plastics. This internal circulation duct is interconnected with the internal space of the incubator. When installing the internal circulation duct, holes can be made in the top plate of the incubator at positions corresponding to the installation locations of the inlet and outlet of the internal circulation duct. Suitable connectors are then used to connect the inlet and outlet of the internal circulation duct to the holes in the top plate. Sealing strips or sealant are used to enhance the sealing of the connection.

[0035] The internal circulation duct contains a catalytic chamber and an internal circulation fan. The air inlet of the catalytic chamber is connected to the inlet of the internal circulation duct. The catalytic chamber contains a heater, a catalytic chamber damper, and a palladium catalyst. The catalytic chamber damper is located between the heater and the palladium catalyst. When the damper is open, the palladium catalyst is in an open state, and air heated by the heater can flow through it. When the damper is closed, the palladium catalyst is in a closed state, and air heated by the heater cannot flow through it. Optionally, the heater can be a PTC heating element. A PTC heating element, also known as a PTC heater, is an electric heater composed of a PTC ceramic heating element and an aluminum tube. It has advantages such as high efficiency and energy saving, long service life, and flexible design. Therefore, using a PTC heating element to heat and dehydrate the palladium catalyst can improve the overall performance of the device.

[0036] The air inlet of the internal circulation fan is connected to the air outlet of the catalytic chamber, and the air outlet of the internal circulation fan is connected to the outlet of the internal circulation duct. When the internal circulation fan is turned on, air in the incubator is drawn into the internal circulation duct by the fan. Passing through the catalytic chamber, the air, heated by the heater, flows over the palladium catalyst, heating and removing moisture. It then enters the fan and returns to the incubator from the air outlet of the internal circulation fan. With continuous operation of the internal circulation fan, hot air continuously flows over the palladium catalyst, effectively removing moisture from the palladium reducing agent and reducing the palladium catalyst. Optionally, the internal circulation fan can be a centrifugal fan. A centrifugal fan is a type of fan in which airflow enters the blade space axially. Driven by the impeller, the airflow rotates with the impeller and gains energy due to inertia, leaving the impeller radially. Work is done by the centrifugal force generated. Compared to ordinary fans, centrifugal fans can more effectively drive airflow in the internal circulation system, achieving a more efficient ventilation effect. Therefore, using centrifugal fans to drive airflow between the incubator and the internal circulation duct can improve the energy efficiency of the entire system.

[0037] In some embodiments, the internal circulation duct is connected to the internal space of the incubator via an exhaust pipe; one end of the exhaust pipe is connected to the air outlet of the internal circulation fan, and the other end is located at the bottom of the incubator. That is, an exhaust pipe is installed between the internal circulation duct and the incubator, and the air generated by the air outlet of the internal circulation fan flows through this exhaust pipe to the bottom of the incubator. In this way, through the continuous circulation of the internal circulation fan, hot air can be evenly distributed inside the incubator, thereby ensuring a uniform temperature inside the incubator and preventing localized overheating.

[0038] In some embodiments, the palladium catalyst dehydration and reduction device further includes: an exhaust damper disposed in the top plate of the incubator; and an exhaust fan disposed above the top plate of the incubator; the air inlet of the exhaust fan is connected to the exhaust damper; the exhaust fan is used to exhaust air from the incubator to the outside of the incubator through the exhaust damper. That is, an exhaust damper is installed on the top plate of the incubator; this exhaust damper can be an electrically operated damper, and the exhaust damper is connected to the air inlet of the exhaust fan. Thus, when both the exhaust damper and the exhaust fan are open, air from the incubator is exhausted to the outside of the incubator. During the dehydration and reduction of the palladium catalyst, the humidity inside the incubator increases. Therefore, during ventilation, the exhaust damper and the exhaust fan can be opened to expel the high-humidity air from the incubator to the outside of the incubator, thereby maintaining the humidity inside the incubator within a suitable range.

[0039] In some embodiments, the palladium catalyst dehydration and reduction device further includes a humidity sensor installed inside the incubator to detect the humidity within the incubator. That is, a humidity sensor is installed inside the incubator because during the dehumidification process, moisture in the palladium catalyst is carried away by the air and enters the incubator, causing the humidity inside the incubator to continuously rise. Therefore, the humidity sensor detects the humidity inside the incubator. When the humidity detected by the humidity sensor no longer increases, it indicates that there is no moisture inside the palladium catalyst. At this point, the heater, catalytic chamber damper, and internal circulation fan can be turned off, keeping the palladium catalyst in a sealed state. Thus, based on the humidity sensor, the operator can accurately monitor the progress of the palladium catalyst dehydration and reduction.

[0040] Furthermore, in some embodiments, the palladium catalyst dehydration reduction device further includes a display control system, comprising a display screen and a controller; the display screen is used to display the detection results of the humidity sensor; the controller is used to control the switching on and off of the heater, the catalytic chamber damper, and the internal circulation fan. In other words, by adding a display control system to the palladium catalyst dehydration reduction device, display and control functions are introduced. This display control system can acquire the detection results fed back by the humidity sensor via wired or wireless means, and then display the results on the display screen, allowing operators to intuitively see the current humidity status in the incubator. At the beginning and end of the dehydration reduction phase, the display control system can send corresponding switching commands to the heater, the catalytic chamber damper, and the internal circulation fan via the controller, achieving full automation of the palladium catalyst dehydration reduction and enhancing the intelligence of the equipment.

[0041] This application provides a palladium catalyst dehydration and reduction device. The device includes an internal circulation duct located above the top plate of an incubator, connected to the interior space of the incubator. The internal circulation duct houses a catalytic chamber and an internal circulation fan. The catalytic chamber contains a heater, a catalytic chamber damper, and a palladium catalyst. Under the action of the internal circulation fan, air from the incubator is drawn into the internal circulation duct, heated by the heater, and then flows through the catalytic chamber damper past the palladium catalyst. The air then enters the internal circulation fan and returns to the incubator from its outlet. With the continuous operation of the internal circulation fan, hot air continuously flows past the palladium catalyst, thus achieving automatic dehydration and reduction of the palladium catalyst. This eliminates the need for manual operation, saving labor costs and improving work efficiency.

[0042] To provide a more detailed explanation of the solution in this application, a specific embodiment is described below:

[0043] This embodiment provides a palladium catalyst dehydration and reduction device for an anaerobic workstation.

[0044] A humidity sensor 17 is installed inside the incubator 10 to detect the humidity inside the incubator;

[0045] An exhaust damper 18 is provided on the top plate of the incubator 10, and an exhaust fan 19 is also provided above the top plate. The air inlet of the exhaust fan 19 is connected to the exhaust damper 17.

The display control system 20 is electrically connected to the internal circulation fan 13, heater 14, catalytic chamber damper 15, humidity sensor 17, exhaust damper 18 and exhaust fan 19 respectively (not shown in the electrical signal transmission path diagram). The display control system 20 receives the detection results fed back by the humidity sensor 17, and controls the switching of the heater 14, catalytic chamber damper 15, internal circulation fan 16, exhaust damper 18 and exhaust fan 19.

[0047] The working process of the palladium catalyst dehydration and reduction device includes:

[0048] S201. Before the anaerobic workstation’s ventilation and deoxygenation work begins, the display control system 20 controls the catalyst chamber damper 15, heater 14 and internal circulation fan 13 to open, so that the air inside the anaerobic workstation is heated by the heater 14 and flows through the palladium catalyst 16 to remove the moisture inside the palladium catalyst.

[0049] S202. The internal circulation fan 15 runs continuously, and hot air flows continuously through the palladium catalyst 16 to continuously dehumidify. During the dehumidification process, the humidity inside the chamber will continuously increase.

[0050] S203, humidity sensor 17 detects the humidity of the air inside the chamber. When the humidity no longer increases, it indicates that there is no moisture inside the palladium catalyst 16.

[0051] S204, The display and control system 20 closes the catalyst chamber damper 15, the heater 14, and the internal circulation fan 13, so that the palladium catalyst 16 is in a closed state;

[0052] S205. During ventilation, the high-humidity air inside the chamber is discharged outside the chamber through the exhaust fan 19, and the dehumidification and restoration are completed.
