Description
Affiliated technical field
The utility model belongs to the incinerator technical field, and what relate generally to is a kind of cement nsp kiln city garbage incinerator.
Background technology
Known city garbage incinerator mainly contains following several: 1, stationary furnace grate furnace.Promptly establish fixed grate in stove, rubbish burns under the condition of stirring not having, and has poor, the easy fusion caking of combustion efficiency, and the defective that the slag burn decrement rate is high is now seldom used.2, mechanical kiln grate furnace.This mechanical kiln grate furnace divides three sections: dryer section, burning zone, burning segment.The slag burn decrement rate reaches 1-2%, and this stove is used more, but slag (accounting for rubbish quality about 70%) can't be handled.3, fluid bed furnace.The rubbish granularity of going into stove needs less than 20 millimeters, and burning is fast, and body of heater is little, and mobile apparatus is few, and the burn decrement rate of slag is low, but operates and the control difficulty, existing also seldom employing.4, rotary furnace.Rotary furnace be applicable to life, industry etc. the burning of various rubbish, it is mainly used in the burning of industrial refuse, also can be used for the domestic waste burning zone, but slag can't be handled.And above several refuse furnace all is not used for cement industry.
Present cement industry is only a few cement plant incineration of combustible discarded object only.Burner as the development of F.L.S (Denmark Smith) company is only applicable to liquid combustible waste material (chemical solvent: useless methyl alcohol, pesticide, agricultural chemicals; Waste oil, waste oil: rosin, tall oil, waste oil mud).By HTC (Heidelberg Cementtechnology Center), the burning combustible waste special equipment (HOTDISC) that Norcem and FLS develop jointly, be applicable to solid-state combustible waste, its size can be saved chopping and powder-grinding process greatly to 1.2 * 0.4m.More than two kinds of combustion apparatus cement sectors also under test, and they not to be suitable for flammable matter content little, dirt, the domestic waste of non-flammable matter such as stone 〉=70%.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of cement nsp kiln city garbage incinerator.Be applicable to burning city domestic garbage, the flammable matter of not only can fully burning, and also raw material and composite material that ashes (dirt in the rubbish, non-flammable matter such as stone) can be used as manufacture of cement are used.
For achieving the above object, the technical scheme that the utility model is taked is: it is made of suspension combustion stove and swinging incinerator, the suspension combustion stove is vertical setting, its upper end is provided with garbage inlet and exhaust outlet, inside has two combustion chambers up and down, the connection position of these two combustion chambers is a throat structure, is provided with the material distributing cone of hierarchal arrangement in two combustion chambers up and down; The swinging incinerator is horizontal setting, drives rotation by drive unit, and the one end is communicated with the bottom of suspension combustion stove, and the other end is provided with sealing device, air inlet and the outlet of rubbish ashes, is evenly equipped with lifting blade in it.
The utility model is reasonable in design, and is simple in structure.It utilizes the heat energy of existing nsp kiln cement producing line that domestic waste is carried out harmless treatment, not only can utilize the flammable matter of rubbish to burn baking cement clinker, but also can utilize whole ashes to make cement raw material and composite material, thereby the sour gas that the alkaline environment that also utilizes the clinker firing system simultaneously comes disposal of refuse to burn and produces is realized the innoxious of garbage disposal, innoxious, recycling treatment to domestic waste provide a good solution, have reduced the cost of manufacture of cement simultaneously.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1, exhaust outlet, 2, garbage inlet, 3, the suspension combustion stove, 4, material distributing cone, 5, throat structure, 6, base plate, 7, stove head seal device, 8, lifting blade, 9, the swinging incinerator, 10, support roller, 11, drive unit, 12, stove tail sealing device, 13, burner, 14, air inlet, 15, rubbish ashes outlet, 16, the ashes cooler.
The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide present embodiment:
As shown in the figure: present embodiment is made up of suspension combustion stove 3 and swinging incinerator 9 two parts, and these two parts are connected by stove head seal device 7.Swinging incinerator 9 is circular cylinder bodies of steel, and suspension combustion stove 9 is horizontal inclined angle setting relatively, and its horizontal tilt is 3-5%, by support roller 10 supportings.Cylindrical shell is provided with the drive unit 11 that drives the cylindrical shell rotation, the low side of stove (burner) is provided with stove tail sealing device 12, outlet 15 of rubbish ashes and burner 13 (can spray into oil or coal dust to keep furnace temperature in stove, guarantee the normal combustion of rubbish), export 15 positions at the rubbish ashes and be provided with discharging air valve and ashes cooler 16.Lifting blade 8 (lifting blade is respectively with 60 degree, and 90 spend, and the forms at 120 degree angles are arranged circumferentially) is housed in stove, and the stove inwall is equipped with refractory material, heat-barrier material and liner plate.Suspension combustion stove 3 is vertical setting, and its profile is square (or circular) cylindrical shell of a steel, and the top is provided with exhaust outlet 1 and garbage inlet 2, and exhaust outlet 1 is connected with the cement slurry dore furnace, and garbage inlet 2 positions are provided with air valve.The connection position that its inside has up and down two combustion chambers and 6, two combustion chambers of base plate is a throat structure 5, is provided with the material distributing cone 4 of hierarchal arrangement in two combustion chambers up and down, and the arrangement of material distributing cone 4 is from top to bottom increase successively each combustion chamber in.Base plate 6 be positioned at the combustion chamber below, it is the angle of inclination and is provided with, effect is that unburnt rubbish is imported in the swinging incinerator 9 smoothly.Suspension combustion stove 3 can be a monotubular, also can be the combination of two or four monotubulars, and its top and bottom connection are got final product.
The course of work of present embodiment is as follows: after rubbish is entered by the garbage inlet of suspension combustion furnace roof portion, light the hot blast (from cement clinker cooler, i.e. " tertiary air ") of rubbish.Tertiary air (700---800 ℃) is from the low side of swinging incinerator, and promptly " burner " enters and the rubbish move toward one another, makes drying garbage, burning, and the hot flue gas of formation escapes and enter the decomposition that dore furnace is used to cement slurry from the top of shower furnace.The ashes that incineration firing stays are discharged by burner.(reject metal through preliminary treatment, granularity after the coarse crushing is less than 30 millimeters) rubbish enter floated incinerator by garbage inlet, in being dispersed in the hot flue gas of rising, material distributing cone carries out drying, burning, the bulk rubbish that has not been suspended drop to reducing place by the effect of spurting of hot flue gas will be wherein lightweight blow go back to the chamber, heavy falls into down the chamber to be disperseed once more, drying, burning.Unburnt rubbish enter in the rotary furnace by the lifting blade in the stove take up be evenly dispersed in burn away in the thermal current until right to the greatest extent after, ashes discharge laggardly to go into the cooling of ashes cooler to be admitted to the cement raw material pre-homogenization yard through conveying equipment more stand-by from the discharging air valve of furnace head.
