Technical Field

The invention relates to the field of solar energy and electrolytic seawater hydrogen production combined utilization, in particular to a method for providing electric energy for an electrolytic seawater system by utilizing solar energy and adding hydrogen generated by electrolysis and ship waste engine oil.

Background

With the activity of global trade, sea transportation has been greatly developed, but the marine environment is seriously polluted, and the main reason is that waste oil generated after large transportation vehicles such as ships and the like use heavy oil with large heat value of combustion and the like as fuel for combustion contains a large amount of sulfur and part of unburnt heavy oil, and in order to meet the requirements of ship berthing, such as the regulations executed from 1 month and 1 day 2010 in the european union, the sulfur content used by ships berthing (including mooring and anchoring) in ports of the european union for more than 2 hours cannot exceed 0.1%; most ships discharge the waste directly into the ocean and use low sulfur oil to land, which causes the most direct pollution to the ocean.

The treated waste engine oil can be recycled, has good use value, but lacks the treatment technology of the waste engine oil in the sea and the waste engine oil is directly discharged to save fuel; or directly store up the used oil and transport and handle the used oil after the bank, and current used oil processing technique can not retrieve according to the used oil particular case, and this kind will consume a large amount of manpower and material resources.

The hydrogen is prepared by consuming a large amount of electric energy in the process of carrying out hydrodesulfurization on waste engine oil, the renewable characteristic of solar energy is utilized, the electric energy can be saved for supplying power to an electrolysis system, secondly, oceans have abundant water resources, the use of fresh water can be reduced by electrolyzing seawater, and after hydrogen is prepared by electrolyzing seawater and is subjected to desulfurization reaction with the waste engine oil, the time of subsequent treatment can be effectively reduced.

And abundant seawater resources and solar energy can provide stable hydrogen sources and electric energy for the whole system.

The invention is mainly realized by the following technical scheme that the system for producing hydrogen by electrolyzing seawater and adding waste marine engine oil, which is powered by a solar cell, comprises a solar cell system and a storage battery. The system is characterized in that direct current required by the seawater electrolysis system is provided by a solar cell, and a pump working simultaneously with the electrolysis system is also powered by the solar cell. When the system stops working, the solar cell charges the storage battery, and simultaneously provides electric energy for the water suction pump and the drainage pump to replace the upper layer solution and the lower layer solution of the water storage tank.

The whole seawater electrolysis hydrogen production and waste engine oil addition system comprises a seawater electrolysis system, a solar cell system, a layered solution storage tank, a waste engine oil conveying system, a trickle bed reaction system, a product storage tank, a hydrogen storage cabinet, an oil conveying pump, an air pump, a pressure gauge, a flange plate, a condensation system and a pipeline. The system is powered by solar energy, hydrogen is produced through electrolysis, a gas transmission pump is injected into a trickle bed reactor, and the hydrogen is conveyed into a waste engine oil storage tank after addition. The trickle bed is cooled by a condensing system as the addition reaction proceeds.

The principle of the invention is as follows: the solar cell supplies energy to the electric consumption devices in the whole system, and the hydrogen is produced by electrolyzing seawater to perform addition reaction with the waste engine oil, so that the sulfur content in the waste engine oil is reduced. Meanwhile, seawater is used for carrying out heat exchange and cooling on the trickle bed, and abundant seawater resources are fully utilized.
