A desulfurization waste liquid purification device

Abstract

The invention discloses a desulfurization waste liquid purification device, which comprises a first desulfurization tank, a second desulfurization tank, a third desulfurization tank and a fourth desulfurization tank; a porous ceramic filter device and a ceramic membrane are installed in the first desulfurization tank, and a porous ceramic The filter device includes a straight-tube ceramic membrane filter tube. The ceramic membrane filter tube is provided with multiple filter channels. One end of the ceramic membrane filter tube is equipped with a liquid collection bucket, and one end of the liquid collection bucket is connected to one end of the ceramic membrane filter tube. One end of the liquid collection bucket is connected with a collision separation straight pipe, and a plurality of collision plates are arranged at equal intervals in the collision separation straight pipe. One end of the collision separation straight pipe is connected with a gourd-shaped ceramic membrane filter, and one end of the ceramic membrane filter is connected with a There are porous ceramic balls in the liquid outlet pipe and the ceramic membrane filter, and a filter orifice plate is installed at the connection between the liquid outlet pipe and the ceramic membrane filter; ceramic fillers and activated carbon are stacked in the second desulfurization tank, and the third desulfurization tank is equipped with There is activated carbon, and a ceramic membrane is arranged in the fourth desulfurization tank.

Description

technical field [0001] The invention relates to the technical field of desulfurization purification equipment, in particular to a desulfurization waste liquid purification device. Background technique [0002] In the process of wet desulfurization, the salt content of the desulfurization liquid will gradually increase, and the accumulation of components such as thiocyanate and thiosulfate will affect the desulfurization effect of the desulfurization liquid, so a part of the desulfurization liquid will be discharged regularly. Part of the desulfurized liquid is then sent to the sintering section for incineration. However, the desulfurization waste liquid contains a large amount of sulfur paste, desulfurization catalyst and other substances. On the one hand, it will cause excessive emissions of sulfur dioxide and hydrogen sulfide in the tail gas, and on the other hand, it will also affect the quality of the sinter. Therefore, it is necessary to treat the desulfurization waste ...

However, the desulfurization waste liquid contains a large amount of sulfur paste, desulfurization catalyst and other substances. On the one hand, it will cause excessive emissions of sulfur dioxide and hydrogen sulfide in the tail gas, and on the other hand, it will also affect the quality of the sinter. Therefore, it is necessary to treat the desulfurization waste liquid for more thorough purification
