Slurry sulfite concentration measuring equipment and desulfurization system

The utility model relates to the field of wet desulphurization, and discloses slurry sulfite concentration measuring equipment and a desulphurization system, which comprise a measuring barrel for accommodating slurry, a flushing device, a slurry injection pipeline, a slurry conveying pipeline, a slurry conveying pipeline, a slurry conveying pipeline and a slurry conveying pipeline, and are characterized in that a slurry inlet and a slurry outlet are formed in two ends of the slurry injection pipeline; the slurry pumping pipeline is communicated to the slurry inlet through a connecting flange, and a first valve is arranged on the slurry pumping pipeline; the water injection pipeline is connected to the part, located between the grout inlet and the grout outlet, of the grouting pipeline, so that flushing water is allowed to flow to the measuring barrel through the water injection pipeline and the grouting pipeline in sequence. By means of the structure, flushing water can be injected from the water injection pi
