Description
The present invention relates to a kind ofly can efficiently burn the rotary kiln incinerator of the horizontal straight line of a large amount of refuses, these refuses comprise the low-calorie refuse or contain the high humidity refuse of more moisture content, as juice, mud, soiling solution, waste liquid, sewage, biological waste and wet discarded object etc., and high calorie refuse, as paper, woodwork and fiber crops.
Term " burning " refers to a kind of process of combustion waste, and wherein, organic matter wherein is oxidized, discharges heat, light or energy.
Refuse can feed the control air by furnace bottom in the pyrolysis oven internal combustion in stove.To produce heat, these heats improve the temperature of coming the combustion waste part to refuse in the burning of pyrolysis oven base section.Organic matter decomposes in succession and volatilizees.Thereby whole trash burnings of furnace bottom become siege (red heat layer), and the upper back refuse decomposes and volatilization (fluosolids).Swallowed up (heat-conducting layer) and gas (gas blanket) is partly resolved in the superiors than top section.By this way, the burning gradually from bottom to top of the refuse in the pyrolysis oven.
This process is called as " distillation ", and process finishes when organic thermal decomposition is finished.Then, owing to the auxiliary combustion in a gas combustion stove begins carbonization, and be heated from the decomposition gas of pyrolysis oven.Sending into necessary air to the gas combustion stove then burnouts refuse.
Thereby in traditional pyrolysis oven, the organic matter in the high-moisture refuse is burning in succession from bottom to top.This pyrolysis oven is unsuitable for the high-moisture refuse such as juice, mud, soiling solution, waste liquid, sewage, biological waste and the wet discarded object etc. that comprise the low-calorie refuse or contain more water, and the refuse of high calorie refuse such as paper, woodwork and fiber crops etc.
About this respect, a dehydrator is installed in the upstream of conveyer line so that the high-moisture refuse is sent into pyrolysis oven.Dehydrator is used for reducing the water content of refuse as far as possible.For this reason, the traditional incinerator equipment that is used to handle the low-calorie refuse also needs a dehydrator except incinerator itself.Perhaps, combustion adjuvant is mixed with refuse improve efficiency of combustion.This combustion adjuvant becomes the fringe cost of burning.In addition, the burner temperature is set as unnecessary high temperature, and this has a strong impact on fuel consumption.On the contrary, the burning that contains the refuse of high calorie of refuse need not to resemble and carries out preliminary treatment the low-calorie incineration of waste.Burner need not be arranged on high temperature.Thereby, be necessary a height calorie refuse is separated with the low-calorie refuse, thereby for handling these refuses, burning facility needs at least two incinerators.This equipment cost is high and many other shortcomings are arranged.
The vertical incinerator of tradition is inserted the refuse that comprises high calorie refuse by its top.Refuse passes incinerator and falls, and utilizes a burner combustion that is positioned at the incinerator bottom.Thereby to control the refuse amount of inserting and ignition temperature is very difficult.This means that this incinerator can not reach completing combustion.In addition, often staying a large amount of ashes or residue has pending.This makes the post processing of staying the residue in the stove complicated.
About this respect, developed horizontal revolving burner as shown in Figure 1, it is disclosed in for example unexamined utility model application No.H06-14730 of Japanese publication.With reference to Fig. 1, an elongated revolving burner 20 comprises a base 21, and a rotating driving device 22 is housed on it.Single cylinder body of heater 23 is arranged on rotating driving device 22 tops in rotatable mode.Rotating driving device 22 comprises a motor 22a and an output gear 22b.The outer surface of body of heater 23 is provided with a cylinder gear 23a.Output gear 2b and cylinder gear 23a engagement are so that body of heater 23 rotations.Body of heater 23 also is provided with flange 23b, 23b, is positioned on the outer surface in right side and left side.Dummy roll 22c, 22c are installed in the right side and the left side of the base 21 that corresponds respectively to flange 23b, 23b.Dummy roll 22c, 22c hold flange 22b, 22b respectively so that body of heater 23 steadily rotates.
As the obvious finding of Fig. 1, single cylinder body of heater 23 is tapered hollow structures.It comprises bottom 23c (being positioned at rear side), wherein is formed with an aperture 23d.An end relative with bottom 23c of body of heater 23 is openend 23e.Bottom 23c diameter is less than openend 23e diameter.One end cap 28 is housed on the base 21 of openend 23e one side.End cap 28 comprises a burner 24, an exhaust apparatus (comprising a dust precipitator) 25, one residual collection mouth 26, a feeder 27.Burner has a fire end that goes out towards body of heater 23 inside.The downward folding of residual collection mouth.Refuse feeder 29 is positioned on the base 21 of bottom 23c one side.Refuse feeder 29 comprises that the spiral 29a and that is mounted in it penetrates aperture 23d and sends into end towards the refuse of body of heater 23.Refuse feeder 29 is connected with hopper 30.Hopper is used to store refuse.Thereby refuse is sent into body of heater 23 with constant basis and is burned.The efficiency of combustion of this rotary kiln incinerator is than above-mentioned traditional pyrolysis oven and vertical incinerator height.In addition, rotary kiln incinerator did not need dehydration before refuse is sent in the stove, and this is necessary in traditional pyrolysis oven.And rotary kiln incinerator needn't use combustion adjuvant or burner 24 is set to high temperature.In addition, because rotary kiln incinerator is not by top refuse to be sent in the stove, so can control and regulate refuse amount and the ignition temperature of sending into easily.In addition, when using the rotary kiln incinerator of described type, the residue that retains in the stove is less.
But, also have some problems as described below.As previously mentioned, the body of heater of rotary kiln incinerator is single drum forms.Thereby when body of heater was used to burn the low-calorie refuse, stove body temperature should be very high.In addition, body of heater need be to rotate with filler in the drying oven than low velocity.On the contrary, when handling high calorie of refuse, furnace body temperature should be lower.Body of heater needs rotation at a relatively high speed so that the remarkable reduction of the efficiency of combustion that prevents to occur.If refuse to be processed not only comprises the low-calorie refuse but also comprise high calorie refuse, for thoroughly burning low-calorie refuse rotary speed is just lower.But high calorie trash burning is bad when the body of heater low speed rotation.Therefore, be necessary to determine best rotary speed and temperature according to refuse to be processed.But this control is difficulty quite, the burning that can not realize ideal.
