On-line methanol reformer using baffle separation mechanism and engine exhaust gas

Abstract

The invention discloses an on-line methanol reformer using a baffle separation mechanism and engine exhaust gas. The on-line methanol reformer comprises a separation section and a reformer. The separation section comprises a separation plate. The separation plate is horizontally assembled on the inner wall of the separation section casing. A liquid collection chamber is formed between the lower part of the separation plate and the inner wall of the separation section casing. The separation plate is provided with a plurality of liquid collecting holes. The top of the inner wall of the separation section casing is fixedly provided with a plurality of upper cooling baffles. The upper surface of the separation plate is fixedly provided with a plurality of lower cooling baffles. The upper cooling baffles and the lower cooling baffles are arranged at intervals. The upper cooling baffles and the lower cooling baffles form an S-shaped cooling and separation channel in the separation section casing. Two sides of the top of the separation section casing are respectively provided with a methanol mixture inlet and a gaseous methanol outlet. The bottom of the separation section casing is provided with a liquid methanol outlet. The on-line methanol reformer can fast realize the gas-liquid separation of the methanol mixture discharged from the reformer and improve the work efficiency of the reformer.

Description

technical field [0001] The invention belongs to the technical field of tail gas waste heat utilization technology, and in particular relates to an online methanol reformer which uses a baffle separation mechanism to utilize engine tail gas. Background technique [0002] Compared with traditional fossil fuels such as gasoline, diesel, and natural gas, hydrogen burns cleanly and has no emissions of particles, hydrocarbons, and carbon monoxide; if lean combustion technology is used, hydrogen combustion can further achieve zero emissions. Therefore, hydrogen has great potential to replace traditional fossil fuels as the main fuel for engines. [0003] However, hydrogen is in a gaseous state at normal temperature and pressure, so it is not easy to transport and store. When using it, it needs to be compressed into high-pressure and high-density compressed hydrogen and stored in a high-pressure container; at the same time, its molecular weight is small and the explosion limit Wide...

AI Technical Summary

Problems solved by technology

Due to the large working space, it is impossible to ensure sufficient contact between methanol and catalyst, methanol and exhaust gas, so its working efficiency and speed are relatively low

Moreover, by figure 1 It can be seen that the size of the solution is relatively large, and it is inconvenient to use due to the limitation of space and weight when used in vehicle-mounted and airborne fields.
