Problems solved by technology
[0002] Sulfur dioxide in exhaust gas has the characteristics of low concentration, wide distribution, great harm and difficult treatment, but the treatment technology currently used is not only costly, but also inevitably produces some secondary waste, which needs further treatment. The device of sulfur dioxide in exhaust gas has the problems of high energy consumption and low desulfurization efficiency, and will generate some secondary waste, causing secondary pollution, and has high requirements for reaction conditions, so it is difficult to popularize

The invention discloses a device for treating sulfur dioxide in industrial waste gas. The device comprises an electrolytic circuit, a filter separator, a liquid storage tank, a peristaltic pump, an electrolytic tank, an anion electrode, a cation exchange membrane, a cation electrode and an electrolyte flow controller; the cation exchange membrane is placed at the middle part in the electrolytic tank and used for dividing the electrolytic tank into two parts; the anion electrode is placed on one side of the cation exchange membrane; the cation electrode is placed on the other side of the cation exchange membrane; the signal output end of the electrolyte flow controller is connected with a one-way valve on an electrolyte inlet pipeline and a one-way valve on an anolyte output pipeline respectively. As the sulfur dioxide in the waste gas is treated by using an ion membrane electrolysis process, manganese steel is used as the anion electrode, the stainless steel is used as the cation electrode and the electrolyte flow controller is also arranged, the device for treating the sulfur dioxide in the industrial waste gas, disclosed by the invention, has the characteristics of low energy consumption and high sulphur removal efficiency.
Description
technical field [0001] The invention relates to a device for treating sulfur dioxide, in particular to a device for treating sulfur dioxide in industrial waste gas. Background technique [0002] Sulfur dioxide in exhaust gas has the characteristics of low concentration, wide distribution, great harm and difficult treatment, but the treatment technology currently used is not only costly, but also inevitably produces some secondary waste, which needs further treatment. The device for sulfur dioxide in exhaust gas has the problems of high energy consumption and low desulfurization efficiency, and will generate some secondary waste, causing secondary pollution, and has high requirements for reaction conditions, which is difficult to promote. Contents of the invention [0003] The object of the present invention is to provide a device for treating sulfur dioxide in industrial waste gas in order to solve the above problems. [0004] In order to achieve the above object, the pre...
