Description
Technical field
The present invention relates to garbage combustion devices.
Background technique
The waste incineration of burning disposal is carried out in waste uneven and flammable to urban waste, industrial waste etc.
In device, burned to as the rubbish for being incinerated object, furthermore, it is desirable to by when burning the harmful substance that is discharged inhibit at
Minimum limit.In addition, in the facility for being provided with boiler, it is desirable that using the higher UTILIZATION OF VESIDUAL HEAT IN of efficiency as target.In order to make this two
Person meets, it is necessary to be the facility that extra air investment incinerator is not realized to completely burned with lower oxygen concentration.
The reason is that if excessive Cryogenic air is put into incinerator, ignition temperature drop in order to improve oxygen concentration
Low and generate imperfect combustion, harmful substance increases or efficiency reduces.In addition, if increasing air capacity, the electric power of air blower at
This rising, and exhausted air quantity increases.If increasing air capacity, useful metal is more aoxidized, and accordingly, there exist the recycling of metal
A possibility that recycling cost increase.On the contrary, oxygen concentration is too low if reducing air capacity excessively, then the production of harmful CO is generated
Raw amount increases such problems.
Shape, the size of urban waste, industrial waste etc. are multifarious, and various substances twine network together.All the time,
There is known various rubbish feed systems (the rubbish supply units such as rubbish supply machine), if substantially distinguishing, there is broken rubbish
Rubbish and carry out the system of rubbish supply and carry out system the two systems of rubbish supply with no crumbling method.With no crumbling method
The system of rubbish supply is carried out compared with broken and carry out the system of rubbish supply, is substantially influenced by rubbish character.That is, by
The size of the rubbish of supply is varied, and rubbish supplies the discharge characteristic of machine (rubbish supply unit) significantly by the shadow of its character
It rings.
For example, rubbish supply machine be screw rod (screw) form in the case where, can following formula find out conveying weight.In Q
In=60 × Φ × π × D × D/4 × S × N × γ formula, the outer diameter of D=helical blade, the screw pitch of S=screw thread, Φ=section effect
Rate, the revolving speed of N=screw rod, γ=specific gravity (conveyer calculating method Zhen Dao fourth of the twelve Earthly Branches Taro writes engineering Book Publishing).In the formula,
Section efficiency and specific gravity change because of substance.Thus, using screw rod transmission urban waste etc., conveying capacity is significantly
It is influenced by rubbish character.
In addition, there is the case where rubbish bigger than screw diameter is put into, to swallowing up for screw rod without broken
The case where being obstructed, carrying out screw rod transmission with constant basis is impaired.Moreover, being deposited in the case where rubbish is fallen from the end of screw rod
In following situation: rubbish twines network each other, becomes bulk, does not fall easily.Also, pendency is fallen quickly in the groove portion for falling mouth.
These problems are the peculiar problems such as urban waste, industrial waste that shape is widely varied, especially in nothing
It is more significant in the case where broken.Generally as the fluidized bed incinerator of garbage combustion device since the starting of burning is easy, combustion
The result of burning ash obtained is dry and clean, therefore, the incinerator suitable for urban waste.But, due to burning velocity compared with
Fastly, so the variation of the quantity of refuse of investment can significantly influence the variation of burning.As its countermeasure, the flowing of flow media is carried out
Slowization of change, the faster rubbish supply amount control of the response that brightness in furnace is utilized, the control of auxiliary air amount.
In order to reduce quantity of refuse variation influence, most preferably inhibit the variation of rubbish supply amount, for this purpose, as to from rubbish
, there is stream documented by such as Japanese Unexamined Patent Publication 2000-356334 bulletin in the method that the rubbish that rubbish supply machine is fallen is measured
Change bed incinerator.In the fluidized bed type incinerator, can observe rubbish from rubbish supply machine rubbish outlet
The position of situation under clan is equipped with television camera.It is fallen using television camera to dangling from the outlet of rubbish supply machine
Under rubbish shot, utilize image procossing (binaryzation of image) to calculate the center of gravity and area of rubbish taken.In this way
One, it utilizes the center of gravity of calculated rubbish and area to calculate and separates each of rubbish when falling from the outlet of rubbish supply machine
A amount.Using the movement speed of center of gravity and the product of area as the amount of rubbish.It can be according to the amount of the rubbish calculated, to rubbish
Rubbish supply amount, primary air amount (moving air amount), auxiliary air amount are controlled.
This method calculates the area of the rubbish fallen from the outlet pendency of rubbish feedway.The rubbish of pendency is sometimes temporary
When be stranded in the outlet of rubbish feedway.There are the following problems: the rubbish along delay can not be identified using the binaryzation of image
The rubbish that the surface layer of rubbish is fallen can not accurately hold supply amount.For example, existing on the bedding of white in same color
White garbage can not examine the rubbish fallen in the case where the bedding of white is detained, white garbage is fallen on it
It surveys.In the image information that color, brightness etc. are obtained by television camera, identical (the identical face of image information can not be identified
Color or identical brightness etc.) rubbish fallen and the rubbish not fallen.In Japanese Unexamined Patent Publication 2000-356334 bulletin, in phase
In the case where rubbish with color, the rubbish fallen and the rubbish not fallen cannot be distinguished from.The rubbish of same color the case where
Under, absolutely not consider to be individually recognizable the rubbish fallen and the rubbish not fallen.As a result, accurate rubbish can not be calculated
Amount.

(pixel A) and the output of pixel (pixel B) detected with 180 ° of phase difference are compared, if then rubbish be in away from high speed light source away from
From the position for 0m, then 100% voltage is generated in the output of pixel A, does not generate voltage in pixel B.The output is with away from height
The distance of fast light source is separate and changes, with apart from separate, the pixel set in a manner of being detected when phase difference is larger
Output becomes larger.
Since the output of the different pixel of phase difference is different, to speculate phase difference, distance is calculated according to phase difference.Example
Such as, for 270 ° of phase difference of output corresponding with remote object is in, object is in more remote output more
Greatly.In fact, the phase difference (that is, remote) of 360 ° of wholes can not be only coped with two phase differences, therefore, in each photographed frame
In, by be set to 0 °, 90 °, 180 °, 4 pixels close on the cmos image sensor of 270 ° of phase difference be set as 1 group, to 4
The output of pixel is compared, it is ensured that the measurement accuracy of distance.
