Description

Technical Field

[0001] This invention relates to the field of new energy technology, and in particular to a test bench for methanol reforming hydrogen production devices. Background Technology

[0002] Against the backdrop of new energy sources gradually replacing traditional energy sources, hydrogen energy, as an important component of new energy, has received increasing attention and focus from governments and society. Hydrogen, as the primary carrier in hydrogen energy applications, currently faces challenges such as high storage and transportation costs and significant technical difficulties, primarily because hydrogen is a gas. Therefore, using methanol as a hydrogen carrier has become the most effective and mainstream technical solution for solving hydrogen storage and transportation problems, leading to the development of many methanol reforming hydrogen production devices. However, current methanol reforming hydrogen production devices face issues such as uneven performance of reforming catalysts, significant differences in device temperature distribution, and the need for calibration of the device's temperature control characteristic parameters.

A drive plate 45 is slidably provided and is slidably connected to the inner wall of the storage tank 56. A limiting rod 46 passes through the drive plate 45. The lower end of the second screw 55 is rotatably connected to the partition plate 44. The second screw 55 extends upward into the storage tank 56 and is rotatably connected to the extended position of the storage tank 56. The upper end of the second screw 55 is rotatably connected to the upper side wall of the storage tank 56. The drive plate 45 is also threadedly connected to the second screw 55. The storage tank 56 is connected to the hollow shaft 42 through a connecting assembly.

[0064] Preferably, the connecting assembly includes a pipe 54, which is connected to the upper end of the storage tank 56. A valve 52 is connected to one side of the pipes 54 that are close to each other. A bellows 57 is connected to the other end of the valve 52. The other end of the bellows 57 is connected to the hollow shaft 42. A C-shaped pressure relief pipe 47 is also connected to the storage tank 56. The upper horizontal section of the C-shaped pressure relief pipe 47 extends through the storage tank 56 and out of the device housing 36. The lower horizontal section of the C-shaped pressure relief pipe 47 extends through the device housing 36 and into the storage tank 56. The C-shaped pressure relief pipe 47 is fixedly connected to the device housing 36 and the extension position of the storage tank 56. A water outlet pipe 39 and an air outlet pipe are also installed on the device housing 36, and the air outlet pipe is located above the water outlet pipe 39.

[0065] The two storage tanks 56 can contain different solutions or the same solution.

The right storage tank contains a cleaning solution. Those skilled in the art can set the liquids in the two storage tanks 56 according to the actual production needs. They can both be set to the same solution, as long as those skilled in the art want to make better use of the usable gas in the exhaust gas.

[0066] The working principle and beneficial effects of the above technical solution are as follows: When disinfection is required, rotating valve 52 connects the left-side pipe 54 with the bellows 57. The first screw 53 rotates, driving the third gear 48 to rotate. The third gear 48 drives the fourth gear 58 to rotate. The fourth gear 58 drives the second screw 55 to rotate. The second screw 55 drives the drive plate 45 to rise. The drive plate 45 on the left side causes the solution in the left-side storage tank 56 to rise and enter the hollow shaft 42 through the left-side pipe 54, valve 52, and bellows 57. Then, it is pushed up by the hollow block 38. Several nozzles 40 spray out to neutralize carbon monoxide in the exhaust gas. When the drive plate 45 on the left causes the solution in the storage tank 56 on the left to rise, a small amount of solution will flow back to the lower part of the storage tank 56 on the left through the C-shaped pressure relief pipe 47 on the left. Since the pipe 54 on the right is not connected to the bellows 57, the cleaning fluid in the pipe 54 on the right will flow through the C-shaped pressure relief pipe 47 on the right to complete the return. After neutralization is completed, the neutralized hydrogen and a small amount of carbon dioxide are discharged through the exhaust pipe (which can be collected and used, and other operations can be performed as needed).

[0067] The liquid in the treatment tank 37 is discharged through the outlet pipe 39. After the liquid is discharged, the valve 52 is rotated to connect the pipe 54 on the right side with the corrugated pipe 57. The drive plate 45 on the right side causes the solution in the storage tank 56 on the left side to rise. It enters the hollow shaft 42 through the pipe 54, valve 52, and corrugated pipe 57, and then is sprayed out by several nozzles 40 on the hollow block 38 to clean the treatment tank 37. The cleaning liquid is then discharged from the outlet pipe 39.

[0068] By setting different solutions in the storage tank 56, the exhaust gas can be better collected and treated. The gas produced after treatment can be collected and reused again, effectively improving the functionality of the device. While the stirring rod 41 rotates, the liquid in the storage tank 56 is discharged through the nozzle 40 by the rise of the drive plate 45, effectively improving the innovation of the device.

[0072] Timer 2: Installed on the second pipeline, used to detect the duration of gas flow in the second pipeline;

[0073] Timer 3: Installed on the third pipeline, used to detect the duration of gas flow in the third pipeline;

[0074] Timer 4: Installed on the fourth pipeline, used to detect the duration of gas flow in the fourth pipeline;

[0075] Timer 5: Installed on the fifth pipeline, used to detect the duration of gas flow within the fifth pipeline;

[0076] Timer 6: Installed on the sixth pipeline, used to detect the duration of gas flow in the sixth pipeline;

[0077] Gas flow meter 1: Installed on the sixth pipeline, used to detect the gas flow rate in the sixth pipeline;

[0078] Gas flow meter 2: Installed on the fifth pipeline, used to detect the gas flow rate in the fifth pipeline;

[0079] The controller and alarm are respectively installed on housing 1. The controller is electrically connected to timers one through six, gas flow meter one, gas flow meter two, and the alarm. The controller controls the alarm based on timers one through six, gas flow meter one, and gas flow meter two, including the following steps:

[0080] Step 1: The controller obtains the detection status index of the test bench based on Timer 1---Timer 6, Gas Flow Meter 1, Gas Flow Meter 2 and Formula (1):

[0081]

[0082] Where K is the test bench's detection status index; M1 is the detection value of air flow meter 3; T1 is the detection value of timer 1; ρ is the density of methanol water vapor; V1 is the detection value of liquid flow meter 1; T2 is the detection value of timer 2; T3 is the detection value of timer 3; M2 is the detection value of mass flow controller; T4 is the detection value of timer 4; P1 is the detection value of gas flow meter 1; T6 is the detection value of timer 6; P2 is the detection value of gas flow meter 2; T5 is the detection value of timer 5; e is the natural constant; δ i Let δ be the detected value of the i-th temperature sensor, and N be the number of temperature sensors; max For any temperature sensor, the maximum value is detected; δ min The minimum value is detected by any temperature sensor;

[0083] Step 2: Compare the test bench detection status index calculated by formula (1) with the corresponding preset detection status index. When the test bench detection status index calculated by formula (1) is less than the corresponding preset detection status index, the controller controls the alarm to sound.

[0084] The working principle and beneficial effects of the above calculation scheme are as follows: First, the detection status index of the test bench is calculated using formula (1). The controller compares the detection status index of the test bench calculated by formula (1) with the corresponding preset detection status index. When the detection status index calculated by formula (1) is less than the corresponding preset detection status index, the controller controls the alarm to sound. When the calculated conveying status index is less than the corresponding preset conveying status index, the controller prompts the personnel that there is a problem with the detection status of this test bench and that they should check in time whether the constant flow pump 26, constant flow pump 24, blower 2, and mass flow controller 34 are working properly. After the check is completed, the constant flow pump 26, constant flow pump 24, blower 2, and mass flow controller 34 continue to work. The controller connects timer 1---timer 6, gas flow meter 1, gas flow meter 2, and the alarm to monitor the detection status index of the test bench. In addition, by setting the alarm to realize the alarm and remind the personnel to check the problem in time, the possibility of test bench failure can be effectively reduced.

If these modifications and variations fall within the scope of the claims of this invention and their equivalents, then this invention is also intended to include these modifications and variations.
