The furnace body 10 is internally formed with a feed passage 12 and a plurality of reaction chambers 13, the feed passage 12 extending in the longitudinal direction and having a top communicating with the feed port 11. A plurality of reaction chambers 13 are arranged at intervals, each reaction chamber 13 is arranged obliquely so that the substance in the reaction chamber 13 can slide from a first end to a second end thereof, and the first end of each reaction chamber 13 is communicated with the feed channel 12.

The plurality of magnetizing units 20 are installed around the furnace body 10 and are arranged in one-to-one correspondence with the plurality of reaction chambers 13. Each magnetizing unit 20 comprises an electromagnetic valve 21 and a plurality of magnetizers 22, and the specific structure of the magnetizers 22 is common knowledge and will not be described in detail herein. The plurality of magnetizing units 20 are each supplied with wind power from a blower 23 and the wind is carried to the magnetizers 22 of the different magnetizing units 20 through pipes 24, and the solenoid valves 21 are used to control the wind generated from the blower 23 to enter the magnetizers 22 of the corresponding magnetizing units 20.

The plurality of partition plates 30 are disposed in the plurality of reaction chambers 13 in a one-to-one correspondence, and partition the corresponding reaction chambers 13 into a fuel chamber 131 and a degradation chamber 132, the fuel chamber 131 is located below the degradation chamber 132, and an igniter is installed in the fuel chamber 131. The plurality of partition plates 30 are each disposed obliquely so that the substance in the degradation chamber 132 can slide down from the first end to the second end of the reaction chamber 13. Each partition plate 30 is provided with a plurality of through holes 31, and the plurality of through holes 31 communicate the fuel chamber 131 with the degradation chamber 132.

The guide plate 40 is disposed in the feed channel 12 and is movable in the longitudinal direction in the feed channel 12. The guide plates 40 are positioned at different heights to sequentially feed the materials in the feed channel 12 into different fuel chambers 131 or degradation chambers 132.

The smoke exhaust pipe 50 is fixedly arranged outside the furnace body 10 along the longitudinal direction and is communicated with the second end of each reaction cavity 13.

The blocking devices 60 are all located in the furnace body 10 and are arranged in one-to-one correspondence with the reaction chambers 13. Each blocking device 60 comprises a first blocking assembly 61 and a second blocking assembly 62. The first blocking member 61 is used for preventing the first end of the reaction chamber 13 from communicating with the feeding channel 12, and the second blocking member 62 is used for preventing the substances in the reaction chamber 13 from sliding down from the second end into the smoke exhaust pipe 50. The second blocking member 62 is provided with a plurality of smoke discharge holes 621.

The collecting tank 70 is arranged on the ground and is positioned right below the bottom of the smoke exhaust pipe 50, and a filter screen 71 is arranged in the middle of the collecting tank 70.

The shower device 80 includes a booster pump 81 and a shower pipe 82. The water inlet of the booster pump 81 is communicated with the bottom of the collecting tank 70, and the water outlet is communicated with the first end of the spraying pipe 82. The second end of the shower 82 is located at the top of the smoke exhaust 50, and the second end of the shower 82 is provided with a plurality of atomizing nozzles 83.

The electromagnetic valve 21, the first blocking component 61, the second blocking component 62, the booster pump 81 and the atomizer 83 are all electrically connected with the electric control cabinet 46 outside the furnace body 10, and the electric control cabinet 46 controls the above devices to work.

The specific working process is as follows: in the initial state, the first blocking assembly 61 is in the closed state, that is, the first end of the reaction chamber 13 is communicated with the feeding channel 12; the second blocking member 62 is in an operating state in which the substance in the reaction chamber 13 cannot slide down into the smoke exhaust duct 50 from the second end thereof.

When a batch of garbage needs to be treated, the worker controls the guide plate 40 to move longitudinally in the feeding passage 12, and when the guide plate 40 contacts the bottom of one of the reaction chambers 13, the movement of the guide plate 40 is stopped. At this time, the combustible material is fed into the feed inlet 11, and the combustible material enters the fuel chamber 131 under the guiding action of the guide plate 40 to be accumulated. The worker then controls the guide plates 40 to ascend and stop moving when the guide plates 40 come into contact with the corresponding partition plates 30. At this time, the garbage is thrown into the feeding hole 11, and the garbage enters the degradation cavity 132 under the guiding action of the material guiding plate 40 to be accumulated. While the first barrier member 61 is operated to prevent the first end of the reaction chamber 13 from communicating with the feed channel 12.

Then, the worker controls the electromagnetic valve 21 corresponding to the reaction chamber 13 to open, and controls the blower 23 to work, so as to introduce magnetized air into the reaction chamber 13. After a certain time, the igniter in the fuel cavity 131 works to ignite the inflammable substance in the fuel cavity 131, and the combustible substance in the garbage in the degradation cavity 132 is ignited because the partition plate 30 is provided with the plurality of through holes 31. The furnace body 10 is heated up, and the generated heat enables the organic matters in the garbage to generate continuous pyrolysis reaction. The continuous pyrolysis reaction generates high-temperature flue gas and landfill leachate, wherein the high-temperature flue gas is discharged from the top of the smoke discharge pipe 50 through the smoke discharge hole 621; the landfill leachate flows into the fuel cavity 131 through the through hole 31 and flows into the collection tank 70 through the smoke discharge hole 621, and fine impurities in the landfill leachate are trapped by the filter screen 71.

Finally, the spraying device 80 works, the filtered landfill leachate is sucked by the booster pump 81 and sprayed on the top of the smoke exhaust pipe 50 through the spraying pipe 82 and the atomizing nozzle 83, and part of leachate is evaporated and then discharged together with high-temperature smoke. Therefore, the landfill leachate can be evaporated and cooled, and the landfill leachate is effectively utilized. After the garbage is pyrolyzed, the worker controls the second blocking member 62 to be in a closed state, and then the fuel chamber 131 and the residue in the pyrolysis chamber fall into the collection tank 70.

When other batches of garbage need to be treated, the garbage of different batches can be sent into other reaction chambers 13 to be treated by the lifting of the material guide plate 40. Because each reaction chamber 13 works independently under the action of the first blocking component 61 and the second blocking component 62, and the influence of each reaction chamber can not be generated, a batch of garbage can be treated, and other batches of garbage can be treated at the same time, so that the working efficiency of the whole low-temperature magnetization degradation furnace is improved.

The high-temperature flue gas carrying the leachate is also treated by the flue gas system 100 and can be safely discharged. Specifically, the flue gas system 100 includes a flue gas outlet pipe 101, a desulfurization tank 102, a heavy metal removal tank 103, and a denitration tank 104. The smoke outlet pipe 101 is disposed along the longitudinal direction and is communicated with the smoke exhaust pipe 50 through a connecting pipe 105. The upper end of the smoke outlet pipe 101 is provided with an electrostatic dust removal device 108, and the purification efficiency of the electrostatic dust removal device 108 is high. The lower end of the smoke outlet pipe 101 is provided with a dust collecting box 109, and dust captured by the electrostatic dust collector 108 falls down into the dust collecting box 109 for convenient collection.

The desulfurization tank 102 is communicated with the bottom of the collecting tank 70, and workers regularly add calcium hydroxide and polyacrylamide agents into the desulfurization tank 102 and stir the calcium hydroxide and the polyacrylamide agents uniformly through the stirrer 107. The high temperature flue gas enters the smoke outlet pipe 101 after passing through the smoke exhaust pipe 50 and the connecting pipe 105. The liquid in the desulfurization tank 102 is sprayed in a connecting pipe 105 through a circulating pump 106, and the sulfur-containing substances in the high-temperature flue gas are neutralized and adsorbed, enter the collecting tank 70, and finally flow back to the desulfurization tank together with the unevaporated percolate. Since calcium hydroxide and polyacrylamide chemicals react with the sulfurized substance to generate a lot of flocculate precipitates, the liquid in the desulfurization tank 102 needs to be periodically filtered by the plate-and-frame filter press 111, and the flocculate precipitates can be filtered out by the plate-and-frame filter press 111.

The liquid in the heavy metal removal tank 103 contains a heavy metal scavenger. The liquid in the heavy metal removal tank 103 is sprayed in a connecting pipe 105 through a circulating pump 106, and heavy metals in the flue gas are removed through a heavy metal catching agent.

The liquid in the denitration tank 104 contains urea for removing nitrogen oxides in the high-temperature flue gas. Because the oxynitride is insoluble in water and non-combustible, urea is sprayed at the outlet of the secondary combustion chamber 110 of the smoke outlet pipe 101, and the oxynitride reacts with the urea at the high temperature (above 850 ℃) of the secondary combustion chamber 110 (the reaction temperature is 950-. The high-temperature flue gas treated by the flue gas system 100 can be safely discharged without causing damage to the environment.

In one embodiment, the furnace body 10 is formed with a guide groove 14 extending in a longitudinal direction, and the top of the guide plate 40 is formed with an inclined guide surface 41, and the lower end of the guide surface 41 is adjacent to the reaction chamber 13. A guide block 42 is installed at one side of the guide plate 40, and the guide block 42 is adapted to the guide chute 14. When the material guide plate 40 stops at different height positions, the material fed from the feed inlet 11 slides down to different fuel cavities 131 or degradation cavities 132 under the action of the inclined material guide surface 41.

In one embodiment, a driving device 43 for driving the guide plate 40 to move in the longitudinal direction is further included. Specifically, the driving device 43 includes a first lead screw 44 and a first motor 45.

The second motor 612 is installed in the first receiving groove 15 and located below the first blocking plate 611, and the second motor 612 is electrically connected with the electric control cabinet 46. The second lead screw 613 is disposed along a longitudinal direction, and the upper end of the second lead screw 613 is in threaded connection with the first blocking plate 611, and the lower end is connected with the second motor 612.

When the first blocking assembly 61 is in the closed state, the first blocking plate 611 is located in the first receiving groove 15, and the top of the first blocking plate 611 is attached to the bottom of the fuel cavity 131, so that the inflammable substance can enter the fuel cavity 131 conveniently. When the first blocking assembly 61 is in an operating state, the second motor 612 rotates, so that the first blocking plate 611 passes through the corresponding insertion hole 32 on the partition plate 30 and then is attached to the top of the reaction chamber 13, and the first end of the reaction chamber 13 is prevented from being communicated with the feeding channel 12, thereby preventing smoke generated during subsequent garbage disposal from being discharged from the feeding hole 11 and the feeding channel 12.

It should be noted that before the garbage is thrown into the feeding hole 11, the worker should control the second motor 612 to rotate, so that the top of the first blocking plate 611 is located in the insertion hole 32 and attached to the partition plate 30, which can block the insertion hole 32, and prevent the subsequently thrown garbage from falling into the fuel cavity 131 through the insertion hole 32. The structure of the first blocking assembly 61 is convenient to control, and a worker can control the communication between the first end of the reaction chamber 13 and the feeding channel 12 only by controlling the forward and reverse rotation of the second motor 612.

When the second blocking assembly 62 is in the closed state, the first electromagnet 623 and the second electromagnet 624 attract each other, the second blocking plate 622 is located in the second accommodating groove 16, and the bottom of the second blocking plate 622 is attached to the top of the degradation cavity 132, so that the residues in the fuel cavity 131 and the pyrolysis cavity can conveniently enter the collecting groove 70. When the second blocking assembly 62 is in an operating state, the first electromagnet 623 and the second electromagnet 624 repel each other, and the first blocking plate 611 is attached to the bottom of the reaction chamber 13, so as to prevent the second end of the reaction chamber 13 from communicating with the smoke exhaust pipe 50.

The structure is convenient to control, and the staff only needs to control the on-off of the first electromagnet 623 and the second electromagnet 624 to control the communication between the second end of the reaction cavity 13 and the smoke exhaust pipe 50.

In one embodiment, a plurality of pressure nozzles 90 are installed in each of the fuel chamber 131 and the degradation chamber 132, and the plurality of pressure nozzles 90 are communicated with a tap water pipe and used for sending the residues in the fuel chamber 131 and the degradation chamber 132 into the smoke exhaust pipe 50. After pyrolysis of the garbage is completed, the plurality of pressure nozzles 90 are opened to flush the residues in the fuel chamber 131 and the degradation chamber 132 into the smoke exhaust pipe 50, so as to prevent blockage during subsequent processing of other batches of garbage.
