Problems solved by technology

[0011] The chemical reaction in the desulfurization process is complicated, the automation control is difficult, and the desulfurization efficiency is generally low. These are the disadvantages in the desulfurization process. Both the desulfurization tower and the desulfurization dust collector inevitably have the above-mentioned disadvantages.

Abstract

The invention provides an intelligent control-type desulfurizing tower. The desulfurizing tower has the structure design of double-layer spraying and double-layer mist removing, and the desulfurization is more thorough; different spraying layers spray different reagents, and the use of only two spraying layers can achieve the effects of efficient desulfurization and maintenance of the stability of the PH value; moreover, the efficient desulfurization can be conducted in both spraying layers so as to ensure the good desulfurization effect of removed flue gas. The intelligent control-type desulfurizing tower achieves automatic spraying and mist removing, can adjust the composition of the spray liquid according to the actual situation in time, and further improves the desulfurization effect from the angle of intelligence. The intelligent control-type desulfurizing tower also can collect the liquid produced in the desulfurization process in time, and return the liquid to the desulfurizing tower for reutilization to reduce costs and save water, and therefore the tower is high in efficiency and friendly in environment.

Description

technical field [0001] The invention relates to the field of environmental protection machinery, in particular to an intelligent control type desulfurization tower. Background technique [0002] Large-scale desulfurization devices for flue gas desulfurization are called desulfurization towers, while small desulfurization and dust removal devices for flue gas desulfurization of coal-fired industrial boilers and kilns are mostly called desulfurization and dust collectors. In the desulfurization tower and desulfurization dust collector, the flue gas containing sulfur dioxide should be used to chemically absorb the sulfur dioxide in the flue gas. In order to strengthen the absorption process, improve desulfurization efficiency, and reduce equipment investment and operating costs, desulfurization towers and desulfurization dust collectors should meet the following basic requirements: [0003] (1) There is a large contact area and a certain contact time between gas and liquid; ...
