Abstract

The invention relates to a desulfuration automatic control system which comprises a control unit used for removing sulfur dioxide in flue gas by controlling a part of the system, a water storage tankwhich is connected with the control unit and is used for storing water, a medical solution tank which is arranged below the water storage tank, is connected with the control unit and is used for storing a medical solution, a mixing tank which is connected with the medical solution tank and the water storage tank separately and is used for storing and mixing the medical solution and the water and adesulfuration pump which is arranged at the outlet end of the mixing tank and is used for outputting a mixed solution. According to the desulfuration automatic control system, a corresponding amountof a desulfurizer is prepared by detecting the concentration of the sulfur dioxide in the flue gas in desulfuration equipment, the amount of the desulfurizer according to a concentration proportion ofthe water and the medical solution is finely adjusted, and the power of the desulfuration pump is adjusted to realize accurate control on the concentration of the desulfurizer so as to realize automatic control, time and labor saving, accurate desulfuration, energy and consumption reduction.

Description

technical field [0001] The invention relates to the technical field of desulfurization automation, in particular to a desulfurization automatic control system. Background technique [0002] Industrial waste gas contains a large amount of sulfur dioxide and nitrogen oxides. Desulfurization is to remove sulfur dioxide in the flue gas. Desulfurization is mainly to remove nitrogen oxides in the flue gas. These two substances will form acid rain when they enter the atmosphere. The harm of acid rain to human beings Very large, coal-fueled flue gas contains these substances, especially in thermal power plants. Now when building power plants, desulfurization and desulfurization equipment must be built at the same time. Most of the desulfurization equipment using wet smoke method only makes industrial flue gas and water fully Exclude after mixing, let the lime or limestone emulsion absorb sulfur dioxide in the flue gas, and generate calcium sulfite hemihydrate or gypsum. The wet smok...
