All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments thereof.
Example 1
Referring to fig. 1 to 4, a furnace body 1 of a small garbage incineration vaporization furnace according to the present invention is internally provided with a fire grate assembly 3, a drying chamber 11, a carbonization chamber 12, a first combustion chamber 13 and a second combustion chamber 14, respectively, the drying chamber 11 is horizontally disposed as a whole and is positioned at the left side of the top of the furnace body 1, the carbonization chamber 12 is vertically disposed as a whole and is positioned at the left side of the top of the furnace body 1, the carbonization chamber 12 is also positioned below the drying chamber 11, and the top of the carbonization chamber 12 is communicated with the left side of the drying chamber 11, the first combustion chamber 13 and the second combustion chamber 14 are separated by a partition plate 4 with the top inclined upward, respectively, and the left ends of the two are communicated with a gap of a bracket on the inner side wall of the furnace body 1 by the partition plate 4.
The material gets into furnace body 1 through the feeder hopper 23 that is located furnace body 1 top to through the inside of first pusher 21 with material propelling movement to drying chamber 11, the bottom downward sloping setting of drying chamber 11 is favorable to the material to independently slide down thereby avoid the material to pile up in the inside of drying chamber 11, and simultaneously first pusher 21 can also promote the inside material of drying chamber 11 left through the thrust of its horizontal direction, also can avoid the material to pile up in the inside of drying chamber 11.
Referring to fig. 4, the material flows into the carbonization chamber 12 after being dried inside the drying chamber 11, and the second pusher 22 is pushed horizontally to the right, so that the carbonized material inside the carbonization chamber 12 is pushed to the top of the left end of the first grate 31, the material falls on the first grate 31 along the parabolic trajectory, the first moving cylinder 33 drives the first grate 31 to horizontally reciprocate, so that the material on the first grate 31 performs peristaltic movement, the first burner 91 is ignited during the peristaltic movement of the material, and the material on the first grate 31 is burned inside the second combustion chamber 14. The second burner 92 is ignited, carbon monoxide in the flue gas in the first combustion chamber 13 is ignited, and the heat generated by the flue gas in the first combustion chamber 13 sufficiently dries the material in the drying chamber 11.
Referring to fig. 6 to 9, in order to realize synchronous and reciprocal movement of the first grate 31 and the second grate 32, the first moving cylinder 33 and the second moving cylinder 34 are hydraulic cylinders of the same type, so as to ensure that the types, specifications and performance parameters of the two hydraulic cylinders are the same, and the two hydraulic cylinders work under the same condition.
During the peristaltic movement of the material over the first grate 31, a substantial portion of the material is combusted and the combusted ash is shaken off the second grate 32, and during the shaking off, the remaining material is combusted substantially in the second combustion chamber 14. The second fire grate 32 moves back and forth along the horizontal direction through the second moving cylinder 34, ash moves on the second fire grate 32 and is conveyed into the slag conveyor 5, and finally, the ash is recovered through the slag conveying device 6.
In the combustion process of the materials in the second combustion chamber 14, the flue gas obtained by combustion flows into the first combustion chamber 13 from bottom to top through the gap, and the first combustion chamber 13 is positioned below the drying chamber 11, so that the materials in the drying chamber 11 are heated by the temperature carried by the flue gas, the materials are heated and dried, and the residual flue gas temperature is utilized. In addition, since the second combustion chamber 14 is adjacent to the carbonization chamber 12, when the material is combusted in the second combustion chamber 14, the material in the carbonization chamber 12 is heated and carbonized, which is beneficial to further combustion of the material and enables the material to be combusted more sufficiently.
Further, the two sides of the drying chamber 11 are respectively provided with a first air supply opening 16 with an inclination angle of 45 degrees, each first air supply opening 16 is in sealing connection with an air supply pipe 18, the dried air is used for conveying materials into the drying chamber 11, and meanwhile, the drying chamber 11 is arranged above the first combustion chamber 13, and the radiant heat of the second combustion chamber 14 can be utilized to improve the drying efficiency of the drying chamber 11.
After the material is ignited, the temperature of the garbage layer can obviously rise to about 400 ℃, at this time, the oxygen begins to gasify with carbon pyrolyzed by the garbage layer to generate CO and the like, and generally 400 ℃ is a temperature limit value for protecting the fire grate (such as the first fire grate 31 and the second fire grate 32), and the temperature on the surface of the fire grate must be prevented from being too high. Therefore, the bottom of the fire grate is provided with four second air outlets 17 which not only provide oxygen for garbage combustion, but also play a role in cooling the fire grate.
The side wall of the furnace body 1 is also provided with a flue gas outlet 15 connected with the first combustion chamber 13, the first baffle plate 71, the second baffle plate 72 and the third baffle plate 73 which are arranged in a staggered manner in sequence are arranged in the first combustion chamber 13, the turbulence effect of flue gas is improved, the combustion time of fuel gas in the second combustion chamber 14 is improved, and fully combusted gas is discharged to a tail gas treatment system through the flue gas outlet 15.
In addition, the left end at the top of the furnace body 1 is also provided with a radar level gauge 8 for controlling the height of the materials in the carbonization chamber 12, so that the first pusher 21 still pushes the materials into the carbonization chamber 12 when the materials in the carbonization chamber 12 are excessively accumulated.
Example 2
This embodiment is different from embodiment 1 in that the movement of the first grate 31 and the second grate 32 is driven by the first moving cylinder 33 and the second moving cylinder 34, respectively, in embodiment 1.
Referring to fig. 5, in this embodiment, only one driving cylinder 35 may be provided, where the driving cylinder 35 has a driving rod 351, a connecting rod 352, a first branch 353 and a second branch 354, where the driving rod 351, the first branch 353 and the second branch 354 are all horizontally arranged, and the first branch 353 and the second branch 354 are sequentially arranged up and down, the connecting rod 352 is vertically arranged and connected with an end of the driving rod 351, two ends of the first branch 353 are respectively connected with a top end of the connecting rod 352 and a bottom of the first grate 31, and two ends of the second branch 354 are respectively connected with a bottom end of the connecting rod 352 and a bottom of the second grate 32, so that the first branch 353 and the second branch 354 are synchronously and equidirectionally driven by the driving rod 351 to move.
