Industrial Application Of Sulfur Dioxide And Hazard Prevention

Sulfur dioxide (SO2), has strong excitant odour, nonflammable, colorless, liquefied easily, easily soluble in water of poisonous and harmful gases.The most common form of sulfur oxides.It is also one of the main atmospheric pollutants, such as sulfur dioxide from coal and fuel oil burning sulfur substance.Volcanic eruptions and forest fires would spit out the gas, also can produce sulfur dioxide in many industrial processes.If further oxidation of sulfur dioxide, usually in the presence of catalyst such as nitrogen dioxide, easy to dust in the air catalytic oxidation, will produce sulfuric acid.

Application:

Sulfur dioxide used as insecticides, fungicides, bleach and reducing agent.Sulfur dioxide is commonly used to bleach pulp, wool, silk, hats, etc., and sulfur dioxide can also inhibitory bacteria breeding, and dried fruit can be used as a food preservative.But it must be strictly in accordance with the relevant state scope and standards used

May bring us potential hazards

When the concentration of sulfur dioxide to 1 PPM most people began to feel stimulation;When the concentration of sulfur dioxide in the atmosphere is more than 0.2 PPM, can make the increased incidence of respiratory diseases, chronic diseases of the patient's condition deteriorated rapidly.Concentration of sulfur dioxide in the atmosphere above 0.5 parts per million (PPM) has potential influence to the human body;In 400 ~ 500 parts per million people will ulceration and pulmonary edema and suffocated.Although sulfur dioxide irritating odor, but our sense of smell is unable to know the concentration of sulfur dioxide.

Method of prevention:

Only the sulfur dioxide detector can accurately detect his concentration.The types of sulfur dioxide portable and on-line, can undertake choosing according to field test need to sulphur dioxide detector.
