This invention provides a fine
slag treatment system for a
settling tank, including a
settling tank, a locking hopper, a feeding channel, a shut-off valve, a
slag discharge channel, a
slag discharge valve, a pressurizing channel, a pressurizing valve, a pressure relief channel, a pressure
relief valve, and a
control unit. The fine slag feeding port at the bottom of the
settling tank is connected to the locking hopper via the feeding channel, and a shut-off valve is installed on the feeding channel. A slag removal
machine is connected to the bottom of the locking hopper via the slag
discharge channel, and a slag discharge valve is installed on the slag discharge channel. This invention sets up a feeding channel at the bottom of the settling tank and connects it to the locking hopper. Through the
control unit, the shut-off valve, slag discharge valve, pressurizing valve, and pressure
relief valve are linked to achieve automatic pressurized discharge of fine slag and its co-
processing with coarse slag, eliminating the need for traditional pumping and
filtration, avoiding
fly ash generation, and reducing
pollution risks. Simultaneously, relying on a
signal acquisition and control module, it achieves
fully automatic operation of the fine slag treatment, improving the
system's
automation level and reducing equipment wear and operating costs.
