Online methanol reformer adopting screen separating mechanism and utilizing engine exhaust

Abstract

The invention discloses an online methanol reformer adopting a screen separating mechanism and utilizing engine exhaust. The online methanol reformer adopting the screen separating mechanism and utilizing the engine exhaust comprises a separating section; the separating section comprises condensation nets, a separating section shell, a liquid collecting cavity and an isolating plate; the isolatingplate is horizontally assembled on the inner wall of the separating section shell; the liquid collecting cavity is formed between the position below the isolating plate and the inner wall of the separating section shell; a plurality of liquid collecting holes are formed in the isolating plate; a plurality of the condensation nets are vertically arranged between the position above the isolating plate and the inner wall of the separating section shell; a methanol mixture inlet and a gaseous methanol outlet are respectively formed in the two sides of the separating section shell; a liquid methanol outlet is formed in the bottom of the bottom of the separating section shell; the liquid methanol outlet communicates with the liquid collecting cavity; the methanol mixture inlet communicates witha reforming methanol outlet of a reformer through a flange; according to the online methanol reformer adopting the screen separating mechanism and utilizing the engine exhaust, the separating sectionis arranged and the condensation nets are vertically arranged in the separating section, so that gas-liquid separating of the methanol mixture discharged from the reformer can be realized quickly; the separated liquid methanol flows back to a methanol box for storing; and the work efficiency of the reformer is improved.

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 wire mesh 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 W...

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.
