The principle of operation of the present invention will now be described as follows: the high-temperature flue gas generated by the combustion of the boiler 1 is discharged through the exhaust pipe 4, meanwhile, cooling water is introduced through the water inlet end of the cooling water pipe 9, the cooling water and the cooling water pipe 9 are utilized to exchange heat with the high-temperature flue gas in the exhaust pipe 4, the high-temperature flue gas can be cooled, the cooled high-temperature flue gas is discharged from the exhaust pipe 4 to the inside of the heat insulation box 6, and can sequentially pass through the heat insulation boxes 6 through the arc-shaped connecting pipes 7 and the ventilation connecting pipes 8, after the high-temperature flue gas enters the inside of the heat insulation boxes 6, the heat of the flue gas can be transferred to the positions of the thermistors 134 through the ceramic heat conduction rings 132 and the heat conduction oil 133 in the ceramic heat conduction rings 132, after the temperature of the positions of the thermistors 134 is increased, the resistance of the thermistors 134 at the same side can be reduced, and thus the current introduced into the inside of the first electromagnetic switch 136 at the same side can be increased, at this time, enough current is introduced into the first electromagnetic switch 136, so that the moving contact of the first electromagnetic switch 136 can be magnetically closed, at this time, the first electromagnetic switch 136 disconnects the connection loop between the first normally open electromagnetic valve 12 at the same side and the first normally closed electromagnetic valve 11 and the controller 20 in the air outlet pipe 10 at the same side, at this time, the first normally open electromagnetic valve 12 at the side keeps an open state, the first normally closed electromagnetic valve 11 keeps a closed state, high-temperature flue gas can smoothly enter the next heat insulation box 6 through the heat insulation box 6, when the temperature of the high-temperature flue gas is cooled to be reduced to a proper temperature by cooling water, the temperature transferred by the high-temperature flue gas cannot raise the temperature of the thermistor 134 at the side to a proper range, so that the thermistor 134 at the position keeps a larger resistance value, so that enough current cannot be introduced into the first electromagnetic switch 136 at the position, so that the moving contact of the first electromagnetic switch 136 cannot be closed, at this time, the first electromagnetic switch 136 at this point cannot disconnect the connection loop between the first normally open electromagnetic valve 12 at this side and the first normally closed electromagnetic valve 11 inside the air outlet pipe 10 at this side, so that the first normally open electromagnetic valve 12 and the first normally closed electromagnetic valve 11 are energized, at this time, the first normally open electromagnetic valve 12 at this point keeps the energized closed state, and the first normally closed electromagnetic valve 11 keeps the energized open state, so that when the flue gas moves to this point, the flue gas will enter the hollow column 5 from the air outlet pipe 10 at this point, so that after the high-temperature flue gas is cooled to a proper temperature, the flue gas will enter the hollow column 5 from the air outlet pipe 10 at this point in advance, and the stability of the temperature of the discharged flue gas is maintained;
the gas pressure in the hollow column 5 is increased by the gas entering the hollow column 5, the electric control valve 193 in the movable ring 192 is closed for 20 seconds after being opened for 30 seconds under the control of the controller 20, and the gas entering the hollow column 5 pushes the movable ring 192 to move upwards in the closed state of the electric control valve 193, at the moment, the smoke dust part in the gas is heavier than the gas part, so that large-particle smoke dust can fall on the lower side of the hollow column 5, and when the electric control valve 193 is opened, the gas on the upper side can be directly discharged through the movable ring 192, and the large-particle smoke dust on the lower side is not easy to be discharged along with the gas, so that the dust removing pressure of the subsequent bag type dust remover 3 is reduced, and the purification effect on the gas dust is improved;
the flue gas discharged through the movable ring 192 enters the air inlet hollow plate 14, then, because the water vapor in the flue gas is lighter, the flue gas containing the water vapor enters the box body 162 through the upper ventilation pipe 163 at the upper side, at this time, the moisture absorption balls 165 positioned in the box body 162 can quickly absorb the water vapor in the flue gas, while the flue gas containing a large amount of smoke dust is discharged into the air outlet hollow plate 15 through the lower ventilation pipe 161 at the lower side, if the humidity in the flue gas is higher, the moisture absorption balls 165 positioned in the box body 162 absorb more moisture, at this time, the weight of the moisture absorption balls 165 is higher, so that the insulating block 166 can be driven to move downwards, further, the rectangular cavity 211 in the insulating block 166 can be synchronously moved downwards, at this time, the conductive block 213 connected with the rectangular cavity 211 moves downwards, until the second electromagnetic switch 169 is electrified after contacting with the other conductive block 213, at this time, the controller 20 receives the electric signal of the second electromagnetic switch 169, so that the two second normally closed electromagnetic valves 173 in the heat exchange tube 171 and the second normally open electromagnetic valve 174 in the exhaust tube 4 can be controlled to be electrified, at this time, the flue gas exhausted by the exhaust tube 4 enters through the air inlet end of the heat exchange tube 171 and passes through the inside of the storage bin 172, the high-temperature flue gas can exchange heat with the coal in the storage bin 172 through the heat exchange tube 171, so that the high-temperature flue gas can be utilized to evaporate the moisture in the coal to be combusted, the moisture in the coal to be combusted is reduced, if the moisture in the flue gas is less, the weight of the moisture absorbing ball 165 is not excessively increased, namely the downward moving distance of the moisture absorbing ball 165 is smaller, so that the two conductive blocks 213 on the same side are not contacted, namely the second electromagnetic switch 169 is not electrified to work, and the two electromagnetic push rods 168 are electrified alternately every 5 minutes under the action of the controller 20, that is, when one electromagnetic push rod 168 is electrified, the other electromagnetic push rod 168 is powered off, the powered-off electromagnetic push rod 168 can recover the movable end of the electromagnetic push rod 168 under the action of the self elastic element, so that the corresponding fixed block 167 can be driven to move upwards, the fixed block 167 can drive the same-side moisture absorption ball 165 to move upwards through the same-side return spring 215 and the insulating block 166 and enter the same-side cylinder 164, meanwhile, the T-shaped plate 22 can seal the bottom of the same-side cylinder 164, the controller 20 controls the electric heater 23 on the same-side to work, the electric heater 23 on the same-side works to generate heat, the moisture in the moisture absorption ball 165 can be evaporated and discharged through the steam discharge hole 24, and when the electric heater 23 on the side electromagnetic push rod 168 is electrified, the upper ventilation pipe 163 and the lower ventilation pipe 161 can enter the bag-type dust collector 3 through the bent pipe 18, and the smoke dust in the smoke can be purified through the bag-type dust collector 3.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
