TECHNICAL FIELD

[0001] The present application relates to the technical field of chemical reaction experiment instrument preparation, in particular to a combined device for high-pressure gas phase chemical reaction. BACKGROUND

[0002] In chemical experiments, gas phase chemical reactants are transported to the reactor through pipelines during the reaction, and then enter the next reaction process after the reaction in the reaction device. This method requires multiple reaction equipment, reaction instruments and pipelines to be connected with each other, which is complicated to operate. Currently, the Chinese invention patent "Modular gas phase catalytic reaction and characterization device", with the publication number CN114778754A, discloses a modular gas phase catalytic reaction and characterization device, which is characterized in that it comprises: 1, a gas distribution module: the gas distribution module is used to adjust the gas components required for catalytic reaction; 2, a reaction module: the reaction module is used to place the catalyst and control the temperature of the catalyst bed, so that the gas contacts and reacts with the catalyst; 3, a detection module: the detection module is used to detect the gas components after the catalytic reaction; a plurality of gas path connecting blocks are provided with an air inlet and an air outlet, the air inlet of the gas path connecting block and the air outlet of the gas path connecting block are communicated inside the gas path connecting block, and the air inlet of the gas path connecting block and the air outlet of the gas path connecting block are arranged on the same end surface of the gas path connecting block; the air inlet of the gas distribution module is used to communicate with the gas supply equipment, the air outlet of the gas distribution module is in butt joint communication with the air inlet of the first gas path connecting block, the air outlet of the gas path connecting block is in butt joint communication with the air inlet of the reaction module; the air outlet of the reaction module is in butt joint communication with the air inlet of the second gas path connecting block, and the air outlet of the gas path connecting block is in butt joint communication with the air inlet of the detection module. Although this patent reduces the use of pipelines in the connection process, the characterization device of this patent connects multiple modules through a bottom plate, and multiple modules are fixed on the bottom plate, which is complicated to operate. Moreover, the gas mixing block in this patent combines and collects multiple gas paths into the reaction block, and the number of air holes on the mixing block needs to be changed according to the number of reaction gas branches. If the number of gas branches required in the reaction process increases, a new type of mixing block that can adapt to the number of gas branches needs to be replaced, and the original gas path needs to be disassembled and reassembled, which will cause the reaction equipment to be unstable. Moreover, the production of this patent is difficult, only professional personnel can assemble it, and its applicability is poor. Meanwhile, the module device in the prior art is made of aluminum, which has poor corrosion resistance and cannot adapt to various corrosive reaction gases. The aluminum module is easily corroded and has general pressure resistance, and can only be applied to medium and low pressure conditions, and cannot adapt to high pressure conditions.

The high-pressure version of the pressure sensor adapter module 6 has four through-holes distributed at the four corners.

[0028] The high-pressure version-universal air outlet connection module 7 includes several fixing holes, a fifteenth air hole 701 and a sixteenth air hole 702, the fifteenth air hole 701 and the sixteenth air hole 702 are connected and located in the same plane.

[0029] The high-pressure version - universal air outlet connecting module 7 has four fixing holes, namely the twenty-fifth fixing hole 703, the twenty-sixth fixing hole 704, the twenty-seventh fixing hole 705, and the twenty-eighth fixing hole 706.

The reaction gas travels in the gas passage formed by the combination of these modules.

[0031] Atmospheric pressure plate device (CN119499991A) The device uses a solenoid valve adapter module as the core of the air circuit control, which can only realize the on-off control of the air circuit. The eighth and ninth air ports of the module can be connected to the air inlet of the solenoid valve, the tenth and eleventh air ports can be connected to the air outlet of the solenoid valve, and the nineteenth and twentieth fixing holes can be used to fix the solenoid valve. In terms of pressure detection, basic detection is only achieved through the pressure sensor adapter module. The twelfth air port of this module can be connected to the pressure sensor measuring port. There is no dedicated pressure regulation module, so the air circuit pressure cannot be actively adjusted. Gas distribution control relies on the mass flow meter adapter module, and its fifteenth air port can be connected to the mass flow meter.

[0032] The overall design lacks corrosion resistance and high-pressure adaptability, and can only meet the basic gas distribution, gas path on / off and pressure detection requirements for normal pressure and non-corrosive gas phase chemical reactions, without active pressure regulation capability.

[0033] High-voltage board device The device eliminates the solenoid valve adapter module and adds a high-pressure version-pressure controller adapter module 5 as the core component for pressure regulation. The tenth vent 501 of module 5 is connected to the pressure controller, and the eleventh vent 502 is connected to the gas path, enabling active and precise control of the gas path pressure. Pressure detection is paired with a high-pressure version-pressure sensor adapter module 6. The twelfth vent 602, thirteenth vent 603, and fourteenth vent 601 of this module form a second three-way gas passage. The fourteenth vent 601 is equipped with a pressure sensor mounting structure 604, which can complete the precise pressure detection under high-pressure conditions, forming a "detection-control" pressure control closed loop with the pressure controller adapter module. Gas distribution control is achieved through a high-pressure version-mass flow meter adapter module 4, whose eighth vent 401 is connected to the mass flow meter to ensure gas distribution accuracy.

[0034] Meanwhile, the gas path can be expanded by using the high-pressure version-universal three-way base plate module 2 and the high-pressure version-universal outlet connection module 7. Each new gas path only requires the addition of the above two modules, without the need to disassemble the original gas path, thus ensuring the stability of equipment operation.

[0035] Example 1: Figure 15 Examples show combinations of multiple high-pressure version universal two-way base plate modules 1, multiple high-pressure version universal three-way base plate modules 2, multiple high-pressure version universal adapter pipe modules 3, multiple high-pressure version mass flow meter adapter modules 4, multiple high-pressure version pressure controller adapter modules 5, multiple high-pressure version pressure sensor adapter modules 6, and multiple high-pressure version universal outlet connection modules 7.

[0036] Figures 16-17 Examples include combinations of modules such as the ferrule inlet adapter connecting to the high-pressure version-universal adapter piping module 3, the mass flow meter connecting to the high-pressure version-mass flow meter adapter module 4, the pressure controller connecting to the high-pressure version-pressure controller adapter module 5, the pressure sensor connecting to the high-pressure version-pressure sensor adapter module 6, and multiple high-pressure version-universal two-way base plate modules 1, multiple high-pressure version-universal three-way base plate modules 2, multiple high-pressure version-universal adapter piping modules 3, multiple high-pressure version-mass flow meter adapter modules 4, multiple high-pressure version-pressure controller adapter modules 5, multiple high-pressure version-pressure sensor adapter modules 6, and multiple high-pressure version-universal outlet connection modules 7.

[0037] In this invention, when the fixing holes are connected to each other, the air holes of the two connecting modules can be connected. The size of the modules can be adjusted appropriately according to the usage requirements. The adjustment of the modules and the position and size of the air holes can be adjusted appropriately according to the usage requirements.

[0038] The high-voltage module in this invention is made of stainless steel, which has strong corrosion resistance and can be used with various corrosive reactive gases, avoiding the corrosion defects of aluminum modules. At the same time, it has better pressure resistance, can stably withstand high-voltage conditions, and its structural strength and service life far exceed those of aluminum modules, perfectly solving the problem of insufficient versatility of existing devices.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
