The invention relates to a device for preventing
slurry in a desulfurizing
tower from precipitating, a first
discharge port, a second
discharge port and a feed port are formed in the desulfurizing
tower, the first
discharge port is positioned above the feed port, and the second discharge port is positioned below the feed port; the pressure pump is arranged on the outer side of the desulfurization
tower; one end of the first discharging
pipe is communicated with the first discharging opening, and the other end of the first discharging
pipe is communicated with a feeding opening of the pressurizing pump; one end of the
slurry delivery
pipe is communicated with the discharge port of the pressure pump, and the other end of the
slurry delivery pipe is communicated with the feed port; the slurry disturbing mechanism is arranged in the desulfurizing tower, the slurry disturbing mechanism is communicated with the feeding hole, and the slurry disturbing mechanism is used for jetting and impacting slurry in the desulfurizing tower, so that
solid particles in the slurry are in a suspended state; the first
control switch is arranged on the first discharging pipe, one end of the second discharging pipe is communicated with the second discharging port, the other end of the second discharging pipe is connected to the portion, between the first
control switch and the pressure pump, of the first discharging pipe, and the second
control switch is arranged on the second discharging pipe.
