At present, the business of Baolan enterprise users mainly covers three major business areas: Field 1: Electromagnetic De-white; Field 2: Dedusting, desulfurization and denitrification; Field 3: VOCS organic waste gas treatment.

Source analysis

Mainly containing dust, sulfur dioxide in flue gas, etc., there is no combustion of hydrogen sulphide. Sulfur dioxide and hydrogen sulfide is harmful to the life, SO2 is 2.26 times heavier than air, is a colorless stink with asphyxiation. Data is introduced, long-term exposure to SO2 concentration was 5.23 + / - 0.52 mg/m3, the body class bronchial pneumonia, hepatic cell swelling, eye keratitis lesions.

Physical and chemical properties of the main exhaust components:

Sulfur dioxide (chemical formula SO2) is the most common and simplest sulfur oxide. One of the major atmospheric pollutants. Volcanoes spew the gas when they erupt, and sulfur dioxide is also produced in many industrial processes. Because coal and oil often contain sulfur, sulfur dioxide is produced when burned. When sulfur dioxide is dissolved in water, it forms sulfurous acid. If sulfurous acid is further oxidized in the presence of PM2.5, sulfuric acid (the main component of acid rain) is quickly and efficiently produced. That is one reason to worry about the environmental effects of using these fuels as energy.

Technology

Introduction to the process:

After capturing all the induced draft fan converge to a main line of flue gas, flue gas into desulphurization purification tower, double alkaline or flue gas desulfurization technology is the use of sodium hydroxide or sodium carbonate solution as the desulfurizer, sodium hydroxide or sodium carbonate solution directly into the washing removal of SO2 in flue gas desulfurization tower to achieve the goal of flue gas desulfurization, desulfurization of flue gas into the wet electrostatic precipitator, the wet between anode and cathode line of the electric device put tens of thousands of volts dc high voltage, under the action of strong electric field, corona corona layer around the line, air in the corona layer to avalanche ionization, resulting in a large number of negative ions and small amount of positive ions, This process is called corona discharge; The dust (fog) particles entering the wet electric dedusting device along with the flue gas collide with these positive and negative ions and are charged. The charged dust (fog) particles move towards the anode due to the action of the coulomb force of the high voltage electrostatic field. After reaching the anode, the charge is released, and the dust (fog) particles are collected by the anode, and the dust is collected to form a water film, which is separated from the smoke by gravity or washing from the upper to the lower sump tank or absorption tower.
