Description
Technical field
This utility model relates to Desulphurization for Coal-fired Power Plant field, particularly relates to a kind of adjustable desulfurizing tower of liquid-gas ratio.
Background technology
At present, the various Industrial Boiler of China, stove are all operated by the fuel combustion based on coal, and this process can be produced
Raw substantial amounts of containing sulfur dioxide with the waste gas of flue dust, it is directly discharged in air to cause serious problem of environmental pollution, as
Acid rain, haze weather etc..Along with country and common people's pay attention to day by day to environmental issue, pollute the discharge standard of waste gas and hold
The dynamics of row is stricter, and in numerous wet desulphurization devices, spray tower systems occupies prominent status, but, face
Face new emission standards for sulfur dioxide (GB13223-2011), it will have large quantities of spray column desulfurizers to be difficult to satisfied wanting
Ask.
The pollutant such as the flue dust that can produce due to fire coal, sulfide.The administering method of this pollutant includes dry method, wet method
And half wet process, wherein applying more is limestone-gypsum wet desulfuration.But, the desulfurizing tower air-flow that prior art provides is not
Enough uniform, gas-liquid two-phase contact skewness can cause desulfurized effect not ideal enough.
Existing desulfurizing tower uses spray column mostly, due to factors such as spray droplet size are bigger, is commonly present spray film contact
The problems such as insufficient, flue gas easily escape.And such as use spray art, owing to mist droplet particle size is the least, the flue gas of rising is often
The whereabouts of suppression droplet, affects gas liquid reaction effect, and flue gas carries the up obstruction etc. being also easy to cause demister of a large amount of droplet
Problem.
China's electric power sulfur removal technology is based on limestone-gypsum method wet desulphurization, by pH value and the liquid of regulation desulfurizing agent
Gas ratio can make desulfurizing agent be fully utilized, and desulfuration efficiency has the potentiality reaching more than 98%, but wet desulphurization at present is actual de-
Sulfur rate major part 95%, even below.The main cause causing this phenomenon is gas-liquid mixed weak effect in desulfurizing tower, by cigarette
Temperature flow rate effect is the biggest；When upstream equipment controls and operating mode changes, if can not adjust in time, not only result in de-
Sulphur efficiency reduces or desulfurizing agent waste, it is also possible to can cause blocking and the fouling of equipment, the grade of desulfurization product declines.The most such as
What combines upstream equipment control and work information, immediately regulates liquid-gas ratio, and reasonable adjusting desulfurizing agent pH value is that desulfurization technology is wanted
The problem solved.
Because above-mentioned defect, the design people, the most in addition research and innovation, adjustable de-to founding a kind of liquid-gas ratio
Sulfur tower so that it is have more the value in industry.
