Methanol-water reforming hydrogen production and power generation unmanned sweeper

Abstract

The invention discloses a methanol-water reforming hydrogen production and power generation unmanned sweeper. The unmanned sweeper uses the methanol-water reforming hydrogen production and power generation device as a power supply, and comprises a methanol water tank module, a hydrogen production machine module, a power generation module, a servo system and a control terminal, wherein the methanolwater tank module is connected with the hydrogen production machine module through a pipeline, the hydrogen production machine module is electrically connected with the power generation module, the power generation module is electrically connected with the 48VDC storage battery, and the servo system is electrically connected with the power generation module and the control terminal. The methanol-water reforming hydrogen production and power generation unmanned sweeper is simple in structure, convenient to use, energy-saving, environment-friendly and safe, and the environment is protected by adopting the technical scheme; the energy conversion efficiency is improved, the economic performance is high, and labor is liberated.

Description

technical field [0001] The invention relates to the technical field of hydrogen production, in particular to an unmanned cleaning vehicle for methanol water reforming to produce hydrogen for power generation. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. [0003] In 2019, the hydrogen energy industry was officially included in the "Government Work Report". Since 2011, relevant national policies have mentioned the development of hydrogen production, hydrogen storage and other supporting facilities; in 2014, relevant policies have proposed to reward new hydrogen refueling stations, but after 2016, national policies are more inclined to ensure Hydrogen fuel cell vehicles do not regress, but there is no mention of relevant subsidies for the construct...

AI Technical Summary

Problems solved by technology

Since 2011, relevant national policies have mentioned the development of hydrogen production, hydrogen storage and other supporting facilities; in 2014, relevant policies have proposed to reward new hydrogen refueling stations, but after 2016, national policies are more inclined to ensure Hydrogen fuel cell vehicles do not regress, but there is no mention of the relevant subsidy policy for the construction of hydrogen refueling stations at the national level

However, there are also many shortcomings. For now, pure electric vehicles have the following defects: 1. There are relatively few people using electric vehicles in the electric vehicle market, so the cost of electric vehicle maintenance is high. Once there is any problem, you must go to a 4S store for repair. Maintenance, the price will be at least 1,000 yuan once it comes down

2. The market share of electric vehicles is very low, so the value preservation and appreciation rate is even lower. Generally, as soon as a newly purchased electric vehicle is in the hands of consumers, it will directly depreciate by more than 60%. It's terrible, you can only use it yourself, and it can be said to be extremely uneconomical if you sell it! 3. Electric vehicles have only one gear, so there is almost no sense of driving. At the same time, the steering wheel of electric vehicles is ambiguous, so there is only one directionality when driving, and there is no precise directionality of the car. Therefore, electric vehicles are known as elderly scooter

4. If electric vehicles are driven in winter, the battery consumes a lot. Generally speaking, a car with an official mileage of 300 kilometers will consume at least one-third of the mileage in winter, so it can run more than 200 kilometers. kilometers, so buying an electric car can be said to be a big problem in driving

6. The charging process of electric vehicles is very troublesome, usually at least two hours, but this is fast charging

There are two shortcomings: 1. The technology is immature, and the price of related products is too high. The cost of two power systems of electric motor and internal combustion engine is far higher than the cost of one power system

2. Driving at high speed or at a constant speed for a long time is not fuel-efficient

And if it is running at a constant speed for a long time, its energy-saving effect will be reduced accordingly.
