Abstract

The invention provides a desulfurization gypsum washing water treatment system, a cleaning method and a control system. The desulfurization gypsum washing water treatment system comprises a filtering device, the filtering device comprises a first shell provided with a filtering cavity, and the first shell is provided with a first inlet and a first outlet which are communicated with the filtering cavity; a filtering substance is contained in the filtering cavity; the anion and cation exchange device comprises a shell provided with an exchange cavity, and the shell is provided with an inlet and an outlet which are communicated with the exchange cavity; anion and cation exchange resin is contained in the exchange cavity; and the first outlet is communicated with the inlet of the exchange cavity through a pipeline. Therefore, the washing water is comprehensively purified, and the reutilization quality of the desulfurization gypsum washing water is improved.

Description

technical field [0001] This article relates to but not limited to the field of construction technology, and in particular relates to a desulfurization gypsum washing water treatment system, cleaning method and control system. Background technique [0002] Desulfurization gypsum is a product of flue gas desulfurization in coal-fired power plants. With the continuous improvement of technology, desulfurization gypsum can basically replace natural gypsum. However, due to the influence of factors such as coal burning and desulfurization agents, there are often a certain amount of impurity elements in desulfurization gypsum, such as potassium, sodium, magnesium, chlorine, etc. Due to the existence of these water-soluble impurities, desulfurization gypsum is used in the manufacture of When building materials products, it will affect the quality of the product. [0003] Desulfurized gypsum often needs to control the content of these water-soluble elements in the application of gyp...
