DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] See also Figure 1-8 The present invention provides a technical solution: an alcohol-based fuel reaction device, comprising a reaction tank 1, wherein the upper and lower ends of the reaction tank 1 are respectively provided with a gas phase inlet 2 and a gas phase outlet 3, characterized in that it also includes:

[0041] Two sets of partition plates 4 are respectively arranged at the upper and lower ends of the reaction tank 1;

[0042] A temperature control unit 5 is disposed between two groups of partition plates 4 in the reaction tank 1 and is used to control the reaction temperature in the reaction tank 1;

[0043] Multiple groups of reaction units 6 are evenly arranged between the two groups of partition plates 4, and are connected to the gas phase inlet 2 and the gas phase outlet 3 through the connecting pipe through the two groups of partition plates 4, and the connecting pipe and the gas phase inlet 2 and the gas phase outlet 3 are provided with gas valves;

[0044] Wherein, the temperature control unit 5 comprises:

[0045] A water inlet 51 is provided on the inner wall of the reaction tank 1 between the two groups of partition plates 4 and is located at the upper end of the reaction tank 1. A water outlet 52 is provided at the lower end of the reaction tank 1 between the two groups of partition plates 4. A heat exchanger is connected between the water inlet 51 and the water outlet 52 via a pipeline.

[0046] The water flow stratification part is arranged in the reaction tank 1 , and is used for the water flowing in from the water inlet 51 to flow in layers and cross in the reaction tank 1 , so as to fully contact with the reaction unit 6 , and provide the required temperature for the reaction in the reaction unit 6 .

[0047] The water flow stratification part includes multiple layers of stratification plates 53, which are evenly distributed from top to bottom in the reaction tank 1. A water flow outlet 54 is opened at one end of each layer of the stratification plates 53, and the water flow outlets 54 opened on two adjacent layers of the stratification plates 53 are opened symmetrically.

[0048] In addition, the reaction unit 6 comprises:

[0049] Multiple groups of reaction tubes 61 are arranged between the partition plate 4 and the layer plate 53 and between two adjacent layer plates 53. The reaction tanks 1 at the uppermost and lowermost ends are connected to the gas phase inlet 2 and the gas phase outlet 3 through the connecting pipes. Two adjacent reaction tubes 61 are connected at one side of the water outlet 54 through the connecting pipe 65.

[0050] It should be noted that a thermometer is provided in the connecting pipe 65 to detect the reaction temperature in the reaction tube 61 and the connecting pipe 65 in real time to ensure that the reaction temperature is at the optimum temperature (generally 260 degrees Celsius with a deviation of about 10 degrees). Since the reaction of synthesizing alcohol-based fuel is an exothermic reaction, when the temperature in the reaction tube 61 is higher than the optimum temperature, the temperature control unit 5 starts to work and cools the reaction tube 61 by heat exchange. At the same time, the temperature control unit 5 can work in a cycle, so as to ensure that the temperature in the reaction tube 61 is always maintained in the optimum temperature range;

[0051] The reaction tube 61 is located at one end of the water outlet 54 and is connected to the inner wall of the reaction tank 1 to form an outlet 62, and the other end is closed. The outlet 62 is sealed by a sealing cover;

[0052] The catalyst assembly is disposed in the reaction tube 61 and is used for catalyzing the reaction gas through the catalyst assembly to synthesize the alcohol-based fuel.

[0053] Meanwhile, the catalyst assembly comprises:

[0054] A plurality of placement cylinders 63, slidably disposed on the reaction tube 61, for placing catalysts;

[0055] The engaging member 64 is disposed between two adjacent placement tubes 63 and is used for engaging and fixing the two adjacent placement tubes 63 .

[0056] In addition, the placement tube 63 includes a tube body 631 and a tube cover 632. The tube body 631 and the tube cover 632 are threadedly connected to each other. The tube body 631 and the tube cover 632 are both hollowed out for gas to pass through.

[0057] At the same time, the engaging member 64 includes:

[0058] Two groups of slots 641 are symmetrically arranged on the cylinder cover 632;

[0059] Two groups of clamping blocks 642 symmetrically arranged at the tail of the cylinder body 631 of the adjacent placement cylinder 63 and used in conjunction with the clamping slot 641, wherein the clamping blocks 642 are provided with slots 643;

[0060] The plug rod 644 is provided at the position of the slot 641 and the tube cover 632 for limited sliding. The tube cover 632 is provided with a slide groove 645 for limited sliding of the plug rod 644. The plug rod 644 is provided with a limit piece 646. The plug rod 644 between the limit piece 646 and the slide groove 645 is sleeved with a spring 647.

[0061] It should be noted that when the catalyst is replaced, there is no need to stop the machine for replacement. You only need to close the gas valves at the connecting pipes on a group of reaction tubes 61 in turn, then open the sealing cover to extract the placement tube 63, and then place the reaction tube containing the new catalyst in the reaction tube 61. You can replace them in turn without stopping the machine.

[0062] Embodiment 2

[0063] The difference between this embodiment and embodiment 1 is that this embodiment also provides a synthesis process for preparing alcohol-based fuel using an alcohol-based fuel reaction device, comprising the following steps:

[0064] Step 1: After the synthesis gas rich in hydrogen, carbon monoxide and carbon dioxide is purified (solid impurities in the synthesis gas are removed), it is sent to the reaction unit 6 in the reaction tank 1 through the gas phase inlet 2;

[0065] Step 2: Collect the pure water formed after being treated by the water treatment unit, then electrolyze the pure water to separate hydrogen and pass it into the reaction tank 1 through the gas phase inlet 2;

[0066] Step 3, place the catalyst in the cylinder body 631 with the cylinder cover 632 opened, and then tighten it by screwing, fill multiple placement cylinders 63 with catalyst in turn, then connect two placement cylinders 63 through the snap-fit ​​piece 64, and then insert the previous placement cylinder 63 into the reaction tube 61 from the outlet 62, connect one placement cylinder 62 to another until the entire reaction tube 61 is filled, and insert the placement cylinder 63 into all reaction tubes 61 in turn, and finally seal the outlet 62 with a sealing cover;

[0067] Step 4: Water of the required temperature for the reaction is introduced from the water inlet 51, and then the water flows through each layer plate 53 in sequence until the space inside the reaction tank 1 between the partition plates 4 is filled so that the water is fully in contact with each layer of the reaction tube 61. After the water flows out from the water outlet 52, the water temperature is adjusted by the heat exchanger, and then the water is sent in again from the water inlet 51 to realize the water circulation;

[0068] Step 5: The synthesis gas introduced into the gas phase inlet 2 reacts under high temperature, high pressure and catalytic conditions of the catalyst to generate gaseous alcohol-based fuel and water, which are finally discharged from the gas phase outlet 3;

[0069] Step 6: Separate the gaseous alcohol-based fuel and water as well as the unreacted carbon monoxide, carbon dioxide and hydrogen, and send the unreacted carbon monoxide, carbon dioxide and hydrogen back into the reaction tank 1.
