Description

Technical Field

[0001] This utility model relates to the field of microchannel reactor technology, specifically a catalytic hydrogenation microchannel reactor. Background Technology

[0002] Microchannel reactors, also known as microreactors, are miniature chemical devices manufactured using precision machining techniques. Their characteristic dimensions typically range from 10 to 300 micrometers, and can even reach 1000 micrometers. The core of these devices is the micrometer- or millimeter-scale microchannels, through which highly efficient heat and mass transfer processes are achieved, significantly improving the efficiency and safety of chemical reactions. Microchannel reactors are widely used in fine chemicals, pharmaceuticals, bioengineering, energy conversion, and other fields.

[0003] A microchannel reactor, as disclosed in publication number CN222093305U, comprises a reactor body and a filter box disposed on one side of the reactor body. The filter box contains a filter chamber and a cleaning chamber. The reactor body is fixedly connected to the filter chamber via a feed pipe. A connecting pipe communicating with the filter chamber is provided on the filter box. The lower end of the cleaning chamber is open. A rotating shaft is rotatably connected within the filter box, and a filter disc is fixedly connected to the outer wall of the rotating shaft. This invention reverse-cleans particulate impurities that clog the filter pores, thereby unclogging the filter pores and ensuring that the filter pores on the filter disc remain unobstructed. This prevents the filter pores from being clogged by particulate impurities, which would prevent materials from passing through the filter chamber into the microchannels within the reactor body for reaction processing, thus reducing the production efficiency of continuous material processing.

[0004] The above-mentioned device has poor temperature control during use and the air inlet is prone to blockage and inconvenient to clean; therefore, we propose a catalytic hydrogenation microchannel reactor to solve the problems mentioned above. Utility Model Content

The first and second docking blocks between the two sets of reactor shells are engaged and connected. Bolt grooves are provided in both the first and second docking blocks. Bolts are provided between the first and second docking blocks between the two sets of reactor shells. The two symmetrically arranged reactor shells are connected by four sets of bolts.

[0014] (1) This utility model provides an inner cavity inside the reactor shell and a temperature monitoring device at the upper end of the reactor shell. The temperature sensor transmits the liquid temperature in the inner cavity to the temperature receiver. The control panel on the temperature receiver can monitor the liquid temperature in the inner cavity in real time. Combined with the inlet and outlet pipes on the upper and lower sides of the reactor shell, the liquid in the inner cavity can be quickly controlled, thus solving the problem of poor temperature control effect.

[0015] (2) By setting a connecting pipe on one side of the upper end of the microchannel tube, by setting a quick installation device inside the connecting pipe, and by setting threads on the inside of the connecting pipe and the outside of the connecting pipe, the effect of quick connection can be achieved by rotation. The connecting pipe and the connecting pipe are both equipped with a second flange at the rear end, and the connection is reinforced by the second flange to prevent gas leakage.
