Description

A kind of high-efficiency titanium dioxide sulfur catalysis remover and its application method
Technical field
The present invention relates to a kind of high-efficiency titanium dioxide sulfur catalysis remover and its application methods, belong to room temperature adsoption catalysis and sky Gas purification techniques field.
Background technique
Sulfur dioxide also known as sulfurous anhydride, it is colourless, with pungent and stinkpot toxic gas, belong to moderate toxicity Substance.It is soluble easily in water after sulfur dioxide sucks respiratory tract by human body, it is largely arrested in the upper respiratory tract, on wet mucous membrane Generating has corrosive sulfurous acid, and a part is oxidized to sulfuric acid, enhances stimulation.If the daily inhaled concentration of human body is The sulfur dioxide of 100 ppm, bronchus and lung will appear apparent irritation after 8 h, and lung tissue is made to come to harm.Big In gas, sulfur dioxide concentration has potential impact to human body in 0.5 ppm or more；In 1 ~ 3 ppm, majority start to feel to pierce Swash；In 400 ~ 500 ppm, people will appear ulcer and pulmonary edema until death by suffocation.Sulfur Dioxide In The Atmosphere can be oxidized to sulphur Acid mist or sulfate aerosol form acid rain with nitrogen oxides, are the important presomas of environmental acidification, lead to soil surface nutrition Substance leaching, nitrogen-fixing bacteria are suppressed, and forest sheet is withered, and meadow and Ecology are seriously damaged, and sulphur is anti-to the physiology of selenium The growth and update for refusing function influence forest make livestock that selenium deficiency disease occur.
It is estimated that in the 1980s, the sulfur dioxide of artificial source emission is at 1.5 hundred million tons or so in outside atmosphere environment. With economic rapid development, the sulfur dioxide (SO2) emissions annual increasing rate that is averaged in the whole world is about 5%.Chinese sulfur dioxide row in 1980 It is high-volume 11,600,000 tons, 2005 are 25,490,000 tons, 23,000,000 tons are down to China's SO2 emissions in 2010, but still position It ranks first in the world.During 13, with the growth of population, economy and the energy, China's sulfur dioxide (SO2) emissions total amount still face Face the trend of growth.And 10 times higher than the Southern Hemisphere of Northern Hemisphere SO2 emissions or more.
When sulfur dioxide mostlys come from kitchen and heating system burning mineral fuel and oil liquefied gas in indoor environment The pollution of generation.If content of sulfur dioxide will be higher by 3 times outdoor in the kitchen of no ventilation condition；Another source is small-sized Heating boiler and commercial coal stove, height of release is low, place disperses and large number of, is not easy to spread, and is low latitude and indoor dioxy The main reason for changing sulphur pollution.
Summary of the invention
The present invention is a kind of high-efficiency titanium dioxide sulfur catalysis remover and its application method, it is characterised in that uses asepsis environment-protecting Type raw material compounds, and is sunk by water, organic solvent absorbent, organic packet and agent, lye, catalyst, stable dispersant and solution-off Depressant prescription composition.The remover, at liquid film, is polluted air through blower and aspirates approach liquid film by feed box spray and runner membrane hanging device Purification is realized in processing.The sulfur dioxide remover product is nontoxic, by absorbing in packet and catalysis, reaction removal air Sulfur dioxide has effects that quickly to remove sulfur dioxide, and the application method makes remover form minor diameter bubble, increases The contact area of sulfur dioxide and absorbent, the more conducively sulfur dioxide in trapping pollution air are added, it is alternate to increase gas-liquid The residence time is contacted, catalyst accelerates the gas to react in the liquid phase with lye, can rapidly and efficiently remove indoor and outdoor true Sulfur dioxide under environment.
