Problems solved by technology
[0008] (1) Use a decolorizing kettle for decolorization, which cannot be continuously produced, has low production efficiency and high labor intensity
[0009] (2) Use the filter cloth filter decolorization tower to decolorize. Although it can be produced continuously, the tower will be blocked after a certain period of decolorization, which has the disadvantages of small flow rate and low efficiency.
It is difficult to replace the filter cloth and filter element, and the labor intensity is high

The invention discloses equipment and method for guaranteeing decolorizing efficiency in the process of extracting salt from coking desulfurization waste solution. The equipment disclosed by the invention comprises a centrifugal pump, a preheater, a decolorizing tower, a basket filter and a decolorizing clear liquid storage tank, wherein the decolorizing tower adopts jacket type design, the condition that high-pressure liquid directly impacts activated carbon is avoided, a filter core and a filter path are processed into special shapes, the activated carbon of large granules in the decolorizing tower can be intercepted, and the repeated use of the activated carbon is realized; the activated carbon with fine granules can penetrate through the decolorizing tower, and a manner of filtration and treatment outside the tower is adopted. Through the adoption of the method disclosed by the invention, the occurrence of tower blockage can be avoided, the continuous production is realized, and the decolorizing efficiency is guaranteed.
Description
technical field [0001] The invention relates to equipment and a method for ensuring efficiency in the process of extracting salt from coking desulfurization waste liquid, and belongs to the field of salt extraction from coking desulfurization waste liquid. technical background [0002] The decolorization process in the salt extraction process of coking desulfurization waste liquid is the key link in whether the coking salt extraction project can produce qualified products. The decolorization process in the current salt extraction project uses the following two devices for decolorization. [0003] 1. Decolorization kettle [0004] When decolorizing, add an appropriate amount of desulfurization waste liquid and activated carbon into the kettle, and after a certain period of heat preservation, the mixed liquid is separated by a separation device. [0005] 2. Decolorization tower of filter cloth filter element [0006] During decolorization, a certain amount of activated carb...
