As shown in FIG. 5, the iron removing device 29 comprises an iron removing conveyor 29-1, a magnet 29-2 and a guide plate 29-3, wherein the magnet 29-2 is horizontally arranged on a bracket between an upper belt segment and a lower belt segment of the iron removing conveyor 29-1 and is tightly close to the upper surface of the lower belt segment, the guide plate 29-3 is obliquely fixed on the bracket at one side of the iron removing conveyor 29-1, the highest end of the guide plate is positioned right below the edge of the lower belt leaving the magnet 29-2, and an iron impurity collecting box 30 is arranged below the obliquely lowest end of the guide plate 29-3. The crushed slag on the conveyor 28 is attracted to the downward belt on the iron removing conveyor 29-1 by the magnet 29-2 and moves together with the downward belt toward the guide plate 29-3. When the iron impurities move out of the action area of the magnet 29-2, the iron impurities will fall on the guide plate 29-3 and finally fall into the iron impurity collecting box 30 due to the loss of the adsorption force.
High-temperature flue gas generated by combustion of the boiler 1 reacts with the urea solution sprayed by the atomizing and spraying device 2 to carry out denitration treatment. And then, the flue gas enters the waste heat boiler 3, and water in the flue gas and the high-temperature flue gas form heat steam after heat exchange and are introduced into a fiberboard production line for use, so that the energy consumption required by the production line is saved. The flue gas after heat exchange passes through the multi-tube dust collector 4 and the bag type dust collector 5 in sequence for dust removal, and the generated furnace dust is conveyed to the furnace dust storage bin 9 by the material sealing pump 14 after passing through the rotary valve 10, the left and right screw conveyors and the blanking pipe 13 in sequence. And the flue gas after dust removal is introduced into a desulfurizer 7 for desulfurization treatment under the action of a fan 6. The flue gases are then discharged into the atmosphere through a stack 8. When the furnace dust in the furnace dust storage bin 9 needs to be conveyed, the trolley is only required to be opened below the furnace dust storage bin 9, and the blanking head on the bulk machine 9-5 is descended to the position of the tank opening of the trolley to carry out unloading operation until the trolley is full. This process completely avoids manual work.
The slag generated by boiler combustion falls into the conveying lifter 17 from the two slag outlets 16 and is conveyed upwards by the conveying lifter 17 until the slag falls into the discharging opening 19 from the discharging hopper 18, the two crushing rollers 26 in the crushing frame 20 are driven by the speed reducing motor 25 and are driven by the meshing of the gear 27 to rotate relatively, and the crushing teeth 26-1 at the upper part of the crushing rollers crush the slag falling into the discharging opening 19 to expose iron impurities in the slag. Thereafter, the slag falls on the conveyor 28 and is subjected to an iron removal operation by the iron removal device 29. The slag after iron removal can be collected and transported to a warehouse by a transport vehicle.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
