Technical field
The utility model relates to plasma chemistry fields, and in particular to a kind of grating type high throughput plasma reaction
Device.
Background technique
Hydrogen sulfide (H2S it is) a kind of hypertoxic, stench sour gas, can not only causes the corrosion of the materials such as metal, but also
It can be detrimental to health, pollute environment.The large and medium-sized oil plant in China is all made of traditional Claus method (Claus) processing and contains at present
H2The tail gas of S, and Recovered sulphur.This method has only recycled the sulphur in hydrogen sulfide, but converts water for valuable hydrogen.From resource
It comprehensively utilizes angle and considers that in traditional hydrogen sulfide recovery process, hydrogen resource is not effectively utilized.Therefore, will
Hydrogen sulfide is decomposed into sulphur and hydrogen has been increasingly becoming the technical field that domestic and international researcher is paid close attention to.
Currently, hydrogen sulfide decomposition method specifically includes that high-temperature decomposition, electrochemical process, photocatalytic method and low-temperature plasma
Body method etc..In aforementioned a variety of methods, high temperature thermal decomposition method relative maturity in industrial technology, but hydrogen sulfide thermal decomposition is consumingly
Limited dependent on reaction temperature, and by thermodynamical equilibrium, though reaction temperature at 1000 DEG C or more, the conversion ratio of hydrogen sulfide
Only 20%.In addition, hot conditions are to the more demanding of reactor material, this also will increase operating cost.Further, since vulcanization
Hydrogen thermal decomposition conversion ratio is low, needs to separate a large amount of hydrogen sulfide gas from tail gas and recycle in systems, therefore also reduce
Unit efficiency and energy consumption is increased, these bring difficulty to its large industrialized application.Although using membrane technology can be with
Product is efficiently separated to break balance limitation, improves hydrogen sulfide conversion ratio, but thermal decomposition temperature tends to exceed the pole of film
Heat resisting temperature is limited, membrane material structure is destroyed.Electrochemistry rule there are operating procedures more, equipment seriously corroded, reaction are steady
The disadvantages of qualitative difference and low efficiency.Photocatalytic method decomposing hydrogen sulfide mainly uses for reference the research of photochemical catalyzing, research emphasis collection
In in terms of developing high efficiency semiconductor.Using solar energy come decomposing hydrogen sulfide, with low energy consumption, reaction condition temperature
It is relatively inexpensive method with simple operation and other advantages.But that there are treating capacities is small for this method, catalytic efficiency is low and is catalyzed
Agent is easy the problems such as inactivation.
Compared with other decomposition methods, low-temperature plasma body method has easy to operate, and device volume is small, and energy efficiency is high
The advantages that, and the reaction being directed to has the controllability of height, and it can be when small treating capacity, being difficult to focus on flexibly
It is applied on ground.Further, since it has the characteristics that high-energy density and can shorten the reaction time, can be realized at a lower temperature
Hydrogen sulfide is effectively decomposed, the changeable occasion of different scales, scattered distribution, working condition is suitable for.Moreover, recycling
While sulphur, hydrogen resource reclaim can be realized the utilization of hydrogen sulfide recycling by low-temperature plasma body method.
Currently, researchers at home and abroad conduct extensive research low temperature plasma decomposing hydrogen sulfide technology, use
Discharge type mainly include glow discharge, corona discharge, sliding arc discharge, microwave plasma, radio frequency plasma and
Dielectric barrier discharge etc..
