Description

Technical Field

[0001] The utility model relates to the technical field of microchannel reactors, in particular to a novel microchannel reactor. Background Art

[0002] Microchannel reactors are reactors with narrow channels (typically ranging from a few hundred microns to a few millimeters in width) designed to facilitate mixing and chemical reactions between fluids. The principle is to utilize the high mass transfer rate and heat transfer efficiency of microchannels to achieve interphase mass transfer and efficient chemical reactions within the microchannels.

[0003] At present, when a microchannel reactor is in use, the experimental liquid in the reaction channel will adhere to the inner wall of the reaction channel during the reaction. The microchannel reactor is not convenient to disassemble, resulting in inconvenience in cleaning the reaction channel, and uneven reaction is likely to occur during the reaction. Utility Model Content

[0004] The purpose of the utility model is to provide a novel microchannel reactor with a stirring structure, which can improve the uniformity of the experimental liquid reaction. The microchannel reactor is provided with an upper and lower shell, which can be separated by an electric push rod, so that the reaction channel can be easily cleaned, thereby solving the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a novel microchannel reactor, comprising a reactor body and a mounting plate, the reactor body comprising a lower shell and an upper shell, the upper end of the lower shell being provided with a lower reaction channel, a rotating shaft being rotatably installed in the lower reaction channel, and stirring blades distributed in an array being installed on the rotating shaft, the upper end of the lower shell being located on the outside of the lower reaction channel and being provided with a lower heating and cooling channel, the upper end of the lower shell being located on the outside of the lower reaction channel and the lower heating and cooling channel and being provided with a sealing groove, the lower end of the upper shell being provided with an upper reaction channel corresponding to the lower reaction channel, and an upper heating and cooling channel corresponding to the lower heating and cooling channel being provided on the outside of the upper reaction channel, the mounting plate being installed on the upper end of the upper shell, the mounting plate being provided with four arranged in an array, and an electric push rod being installed at the lower end of the mounting plate.

[0006] When using a novel microchannel reactor of the utility model, during the experiment, high-temperature liquid is added to the heating and cooling flow channel through the inlet pipe, and the experimental liquid is added to the reaction flow channel from the flow channel inlet. The experimental liquid in the reaction flow channel can be heated by the high-temperature liquid. At the same time, the experimental liquid can push the stirring blade when passing through the stirring blade. Under the action of the rotating shaft, the stirring blade can be rotated. The experimental liquid can be stirred by the stirring blade to mix it and improve the reaction uniformity. When the experimental liquid needs to be cooled, the high-temperature liquid is discharged and coolant is added to the heating and cooling flow channel. The experimental liquid can be quickly cooled by the coolant. After the reaction experiment is completed, the piston rod is extended by the electric push rod, so that the upper shell can be raised and separated from the lower shell. At this time, the reaction flow channel can be cleaned.

[0007] Preferably, an inlet pipe is installed on one side of the lower shell, and an outlet pipe is installed on the side of the lower shell away from the inlet pipe. High-temperature liquid and coolant can be added into the heating and cooling flow channel through the inlet pipe and discharged through the outlet pipe.

[0008] Preferably, the inlet pipe and the outlet pipe are both connected to the lower heating and cooling channel.

[0009] Preferably, the starting and ending ends of the lower reaction channel and the upper reaction channel are respectively provided with a channel outlet and a channel inlet. The experimental liquid can enter the reaction channel from the channel inlet and can be discharged through the channel outlet.

[0010] Preferably, a sealing clip plate adapted to fit within the sealing groove is provided at the lower end of the upper housing, located outside the upper reaction channel and the upper heating and cooling channel. The sealing clip plate is inserted into the sealing groove. When the upper and lower housings are combined, the sealing clip plate can be inserted into the sealing groove, thereby sealing the reaction channel and the heating and cooling channel.

[0011] Preferably, a first fixing plate is installed at a lower position of the outer surface of the lower shell, and a total of four first fixing plates are provided in an array, and the first fixing plates are provided with symmetrically distributed threaded holes.

[0012] Preferably, a second fixing plate is installed at the end of the piston rod of the electric push rod, and a mounting hole corresponding to the threaded hole is opened on the second fixing plate, and a bolt is installed in the mounting hole and the threaded hole. The first fixing plate and the second fixing plate are provided for connecting and installing the upper shell and the lower shell.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the experimental liquid can pass through the stirring blades during circulation, and under the push of the fluid, the stirring blades can stir and mix the experimental liquid, thereby improving its reaction efficiency and reaction uniformity. After the reaction experiment is completed, the upper and lower shells can be separated by the electric push rod, which can facilitate the cleaning of the reaction channel and prevent blockage of the reaction channel.
