Description
Technical field the present invention relates to incinerator inclination inverse-push fire grate structure, particularly relates to the method for utilizing described fire grate structure to burn away the refuse, relates in particular to the method and apparatus that inverse-push fire grate that the branch multistage drives is burnt away the refuse.
The incinerator type that the consumer waste incineration processing is adopted in the background technology prior art is various, and distinguishing by the type of furnace has grate furnace, rotary kiln stove, fluidized-bed furnace and gasification furnace four big classes.The main part of grate furnace is a fire grate, distinguish by the motion mode of fire grate reciprocating type, drum-type is arranged again, rock type etc.; Reciprocating fire grate is divided into forwards formula and inverse-push two classes again.The forwards formula is meant that the direction of fire bars promotion rubbish is identical with the direction that the waste incineration process moves, and inverse-push is meant that the direction of fire bars promotion rubbish is opposite with the direction that the waste incineration process moves.
Reciprocating type backstepping fire grate is stronger to the adaptability of different calorific value rubbish, particularly high-moisture, waste of low heating value is had the good treatment effect, and the garbage burning factory of two megapolis obtains comparatively satisfied effect at home.But it still comes with some shortcomings part need further perfect, for example the Chinese invention patent of the patent No. 02111455.2 disclosed a kind of " domestic waste incineration " by name (following: technical scheme correlation technique 1) is exactly like this:
1) according to the three phases of incineration firing process, the also corresponding definition of its backstepping fire grate part of correlation technique 1 has drying, burns and burns three functional areas, because dry, burn and time of burning three phases and needing has nothing in common with each other, rubbish difference of different nature is also very big, and should there be different requirements three functional areas to the translational speed of rubbish.But its backstepping fire grate can only be moved back and forth with same speed by 1 drive unit because be an integral body, is unfavorable for improving the burning disposal ability and reduces the hot burn decrement rate of lime-ash.
2) the backstepping fire grate of correlation technique 1 all adopts the moving grate that pull bar drives, and belongs to crank connecting rod sliding block mechanism, and crank is outside lower air chamber, and slide block (moving grate frame component) is in lower air chamber, and connecting rod (pull bar) passes lower air chamber's connecting crank and slide block.Because link motion is plane motion, the perforation of lower air chamber must leave bigger gap, and sealing can't thoroughly solve, and has the problem of leaking out.Because one time wind is taken from refuse pit, have stench and pernicious gas, a wind after the heating overflows and looses to causing air pollution and thermal pollution to the working environment between furnace chamber between furnace chamber, also increases the heat loss of incinerator.
3) grate furnace is a more general and masty problem from the slit source ash between the fire bars, the existence of leaking grey problem has increased the load that leaks grey discharger, also may cause the blowing out accident when serious, in addition, leaking ash generally is to be discharged from after being delivered directly to mucking machine and slag mixing, leak in the ash and contain the fixed carbon that does not burn, this will make the hot burn decrement rate of lime-ash improve even exceed the limit value requirement.The backstepping fire grate of correlation technique 1 adopts side plate to compress the slit of eliminating between fire bars, because the pressure of disk spring does not overcome the moving resistance of fire bars, playing the stokehold must lean on artificial gap with fire bars to eliminate, compress with side plate then, in fact disk spring only plays the effect that absorbs the fire bars thermal expansion amount, is the frictional force that has increased between side plate and fire bars, has quickened the rate of wear of fire bars and side plate and adopt spring to press the side effect that brings, along with the wearing and tearing of fire bars, leaking ash will increase gradually.
It is that a wind is to blow by the slit between fire grate segment that the fire grate of correlation technique 1 also has a shortcoming, for being stopped up by ashes in the slit of avoiding blowing, it is that a changing of the relative positions is arranged between adjacent fire grate segment that fire grate back and forth all has an additional move at every turn, thereby has increased the wearing and tearing of leaking between ash amount and fire grate segment.The practical operation situation of a domestic garbage burning factory shows that along with the increase of fire grate segment wearing and tearing, leakage ash amount is also increasing, can cause leaking the fault that obstruction takes place grey discharger when serious.
