Abstract
The invention relates to a hydrochlorination fuel battery and relative application in the alkali-chloride chemical production. The inventive battery has the same structure of common fuel battery, which is characterized in that: the battery uses the chorine and hydrogen gas as fuel, the reacted product is hydrochloric acid solution, and it can replace traditional direction synthesizing method to be used in the hydrochloric acid industry production, while the energy generated by the battery can partly compensate the electric energy consumed by electrolyzing salt water, and complete the cycle usage of part energy in the alkali-chloride chemical production, to reduce the producing cost.
Description
Technical field:
The invention belongs to fuel cell and chemical industry for making chlorine and alkali production technical field, being specifically related to chlorine and hydrogen is formed chlorine hydrogen fuel cell of fuel and the purposes in chemical industry for making chlorine and alkali is produced.
Background technology:
Chlorine industry is to produce the basic chemical industry of caustic soda, chlorine, hydrogen and hydrochloric acid.It is not only supplied raw materials for chemical industry, and its product also is widely used in industrial departments such as agricultural and metallurgy, papermaking, weaving, printing and dyeing, food, electronics, has consequence in national economy.
One of characteristics of chlorine industry are that power consumption is big, and its power consumption is only second to electrolysis and produces aluminium.The power consumption that China's chlorine industry is produced accounts for 1.5% of year gross generation, and electricity expense accounts for 50-60% in the chlorine industry production cost of products.Therefore, various countries are all the time the key problem that cuts down the consumption of energy as chlorine industry.According to literature search, find no the report of chlorine hydrogen fuel cell.
Summary of the invention:
At the big problem of power consumption in the above-mentioned chlorine industry, the energy that chlorine hydrogen fuel cell provided by the present invention produces is used for the part compensation electric energy that electrolytic saltwater consumed, and finishes recycling repeatedly of portion of energy in chemical industry for making chlorine and alkali production.
This chlorine hydrogen fuel cell device is consistent with the general fuel cell structure, it is characterized in that this battery is is the fuel cell that fuel is formed with chlorine and hydrogen.Shown in the accompanying drawing 1, equip the chlorine hydrogen fuel cell to specifications, and form battery group.
The chlorine hydrogen fuel cell feeds Cl

2Dividing potential drop is 5---270kPa, flow velocity 15-320cm
3/ min; Battery operated temperature is-20--200 ℃, and the hydrochloric acid that the battery internal reaction generates concentration 1-33% also flows out cell apparatus, simultaneously, battery output electric energy.
The chlor-alkali fuel cell can be used for the part compensation electric energy that electrolytic saltwater consumed, and finishes recycling repeatedly of portion of energy in chemical industry for making chlorine and alkali production, sees shown in the Figure of description 2.
Concrete reaction of the present invention is as follows:
Above-mentioned being reflected in the chlorine hydrogen fuel cell carried out, and chemical energy is converted to electric energy.As the about 980gCl of battery consumption
2And 30gH
2, can generate 30kg30% hydrochloric acid, the electric energy of the kilowatt-hour of battery output simultaneously.Calculate by theoretical, the electric energy that this reactive applications is produced in the chlorine hydrogen fuel cell can compensate 59.35% of electrolytic saltwater consumed in the chlorine industry electric energy.
In chlorine industry, chlorine that electrolytic saltwater generated and hydrogen, major part just adopts traditional direct synthesis technique at our factory's on-site, promptly uses the composite type hydrochloric acid unit, is also referred to as three-in-one synthetic furnace and produces hydrochloric acid.Chlorine and hydrogen reaction generate hydrogen chloride and water-soluble salify acid product, are energy dispose procedures, and in traditional hydrochloric acid direct synthesis technique, these Conversion of energy are heat energy and not being utilized, and need to consume a large amount of cooling waters on the contrary.Chlorine and hydrogen that chlorine hydrogen fuel cell provided by the invention will utilize direct synthesis technique to consume act as a fuel, and not only finish same hydrochloric acid production, and produce a large amount of electric energy, remedy the power consumption of chlorine industry, greatly reduce the chlorine industry production cost.
