[0020] Please refer to the attached Figure 1-Figure 3 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0021] The utility model proposes a smoke filter mechanism for a high-titanium slag electric furnace. When using the device, the purified liquid is poured into the box body through the liquid inlet pipe of the filter box 1, the cooling water is poured into the box body through the liquid inlet pipe of the heat absorption box 2, a group of filter plates 4 are sequentially inserted into the filter box 3, after the cover plate is screwed on the filter box 3, the outer side of the filter plate 4 is attached to the filter box 3 and the inner wall of the cover plate, the exhaust pipe of the smoke is fixedly connected to the air inlet pipe of the filter box 3, the motor 11 is started, and the motor 11 drives the bevel gear When the smoke is discharged, it first enters the filter box 13, and a group of filter plates 4 of the filter box 13 adsorb and filter the particulate impurities in the smoke. The smoke with particles removed enters the spiral tube 10, and the heat in the smoke is absorbed by the cooling water. The spiral shape of the spiral tube 10 increases the contact between the smoke and the cooling water. The contact area can better absorb the heat in the flue gas. The cooled flue gas enters the air inlet pipe 13 through the connecting pipe 5, and the flue gas is discharged to the bottom of the purified liquid, and the harmful gases in the flue gas are purified by the purified liquid in the filter box 21, and the filtered and purified gases are discharged through the exhaust pipe of the filter box 21. While absorbing heat and purifying the gas, the two sets of stirring rods 7 rotate and stir to make the cooling water in the heat absorption box 2 absorb heat more evenly, so that the purified liquid in the filter box 21 reacts better with the harmful gases, and the smoke dust is filtered more thoroughly. At the same time, the cooling water in the heat absorption box 2 absorbs the heat in the smoke and reduces the heat carried by the smoke dust discharge, and can recycle the heat to reduce energy waste. If a large amount of smoke dust is purified for a long time, the filter plate 4, purified water and coolant are replaced regularly to avoid the filter plate 4 and the purified water being in a saturated state and unable to continue filtering and purifying, and to avoid the coolant temperature being too high and unable to absorb heat and cool down. After use, turn off the motor 11 and discharge the waste water.
