The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1, a honeycomb zeolite calcining furnace provided by the embodiment of the present invention may include a first wave suppression zone 1, a second wave suppression zone 8, a calcining zone 3, a cooling zone 5 and a conveyor belt 9.
Wherein the first wave suppression band 1 and the second wave suppression band 8 are arranged at two ends of the honeycomb zeolite calcining furnace. The calcining section 3 is connected to the first inhibiting section 1, and the calcining section 3 may be plural. One end of the cooling section 5 is connected with the calcining section 3, and the other end is connected with the second wave suppression section 8, and the number of the cooling section 5 may be multiple.
The conveyor belt 9 penetrates through the middles of the first wave suppression band 1, the second wave suppression band 8, the calcining section 3 and the cooling section 5 and is used for conveying the honeycomb zeolite.
In this embodiment, a metal flexible connecting piece 7 is arranged between the cooling section 5 and the calcining section 3. And a metal flexible connecting piece 7 is arranged between the first wave suppression band 1 and the calcining section 3. And a metal soft connecting piece 7 is arranged between the second wave suppression band 8 and the cooling band 5.
As shown in FIG. 2, the calcination section 3 includes aluminum silicate insulation wool 12, a ceramic plate 13, a silicon carbide plate 14, refractory bricks 15, a microwave source 16, and a heating rod 17. The aluminum silicate heat-preservation cotton 12 is filled inside the calcining section 3, the ceramic plate 13 is located below the aluminum silicate heat-preservation cotton 12, the silicon carbide plate 14 is installed below the ceramic plate 13, the refractory bricks 15 are located below the silicon carbide plate 14, the microwave source 16 is located above the aluminum silicate heat-preservation cotton 12, and the heating rod 17 is located between the silicon carbide plate 14 and the refractory bricks 15.
The natural honeycomb zeolite is calcined in the calcining section 3 by a microwave source 16 arranged above the aluminum silicate heat-insulating cotton 12 so as to remove moisture and impurities in the natural honeycomb zeolite. The microwave source 16 is used for calcining the natural honeycomb zeolite, so that the energy consumption can be effectively reduced and the heating speed can be increased.
It should be noted that microwaves are a form of energy (rather than heat), but can be converted to heat in a medium. The reaction of materials to microwaves can be divided into four cases: penetrating microwaves; reflecting the microwaves; absorbing microwaves and partially absorbing microwaves.
Generally, in the field of energy processing, the processed materials are mostly dielectric materials, and the dielectric materials usually absorb microwave energy to different degrees, and the dielectric materials and the microwave electromagnetic field are coupled with each other to form various power dissipation and therefore the purpose of energy conversion of the channel is achieved. There are many ways of energy conversion, such as ion conduction, dipole rotation, interface polarization, hysteresis, piezoelectricity, electrostriction, nuclear magnetic resonance, ferromagnetic resonance, etc., where ion conduction and dipole rotation are the main principles of microwave heating. Microwave heating is a heating mode which converts microwave energy into heat energy by means of absorption of the object, so that the whole body of the object is heated at the same time, and is completely different from other conventional heating modes. The traditional heating mode is that heat is transferred to material heat from the outside according to the heat conduction, convection and radiation principles, the heat is always transferred from the surface to the inside to heat materials, a temperature gradient inevitably exists in the materials, so the heated materials are not uniform, the materials are locally overheated, the heating technology is influenced and different from the traditional heating mode, the material temperature is increased by generating 'internal friction heat' through the high-frequency reciprocating motion of dipole molecules in the heated body, the inside and the outside of the materials can be simultaneously heated and simultaneously heated without any heat conduction process, the heating speed is high and uniform, and the heating purpose can be achieved only by one or more than one of the energy consumption of the traditional heating mode. From theoretical analysis, the amount of heat generated by a substance in a microwave field is greatly related to the kind of the substance and the dielectric property thereof, i.e. microwaves have the property of selectively heating the substance.
In this embodiment, the honeycomb zeolite calcining furnace may further include a fan 10 and two gas-collecting hoods 11, where the two gas-collecting hoods 11 are respectively disposed at the free ends of the first wave suppression band 1 and the second wave suppression band 8, and the fan 10 is installed between the two gas-collecting hoods 11.
The fan 10 and the two gas collecting hoods 11 are used for processing hot gas generated by the first rejection band 1 and the second rejection band 8. Specifically, the gas collecting hood 11 disposed at the free end of the second wave suppression band 8 is used for collecting the hot air emitted from the cooling section 5, and the hot air is introduced into the gas collecting hood 11 disposed at the free end of the first wave suppression band 1 through the fan 10, and enters the calcining section 3 to perform hot air circulation.
With further reference to fig. 1, the honeycomb zeolite calciner also includes a first support 2, a second support 4, and a third support 6. The first wave suppression band 1 and the second wave suppression band 8 are installed on the first support 2, the calcining section 3 is arranged on the second support 4, and the cooling section 5 is located on the third support 6. It will be understood that the first support 2 is used to mount the first and second quench zones 1 and 8, the second support 4 is used to fix the calcining section 3 and the third support 6 is used to house the cooling section 5.
In summary, the natural honeycomb zeolite provided by the present invention firstly enters the first wave suppression band 1 through the conveyor 9 and then enters the calcination section 3, the microwave source 16 disposed above the aluminum silicate insulation wool 12 is used to calcine the natural honeycomb zeolite in the calcination section 3 to remove moisture and impurities in the natural honeycomb zeolite, and the calcined natural honeycomb zeolite is sent to the cooling section 5 through the conveyor 9 to be cooled, because the microwave source 16 is not disposed in the cooling section 5, the zeolite can be gradually cooled down in the cooling section 5, the cooled zeolite enters the second wave suppression band 8, the first wave suppression band 1 and the second wave suppression band 8 can prevent the microwave from leaking to the outside, and because the microwave source 16 is used to calcine the natural honeycomb zeolite, the energy consumption can be effectively reduced and the heating speed can be increased.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
