Specific embodiment
Further to illustrate technological means and its effect that the utility model is taken, below in conjunction with of the present utility model
Preferred embodiment and its accompanying drawing are described in detail.
A kind of anti-coking waste incineration system, is mainly used in solid waste burning processing system, and solid waste enters
After rotary kiln 10, burned at a temperature of 900 ~ 1000 DEG C and form melt flow stream, flue gas enters dual firing chamber 20, and indoor temperature is more than
1100 DEG C, flue gas is more than 2s in the residence time of dual firing chamber 20, solid waste is fully burnt completely.In this technological process,
Due to the join domain of rotary kiln 10 and dual firing chamber 20, particularly it is burning blind area below the join domain and has water vapour
It is relatively low from the upward loss of device for dragging dregs 30, temperature so that the high-temperature fusion stream of rotary kiln tail end 11 and the bottom of dual firing chamber 20
Body cooling deposition forms coking.As the coking of rotary kiln tail end 11 is more and more, the internal capacity of rotary kiln 10 is caused gradually to contract
It is small, and when the coking of rotary kiln tail end 11 increases to certain thickness, the rotary kiln 10 for being designed with certain inclination angle makes material
Can also be disappeared to the power that rotary kiln tail end 11 flows along rotary kiln head, influence the treating capacity and treatment effect of solid waste,
Ultimately resulting in CIU cannot run.The coking of 20 side wall of dual firing chamber 21 can block the relative with rotary kiln tail end 11 of dual firing chamber 20
Side wall 21 on hygrosensor and observation panel, interference production is normally carried out.
Fig. 1 is refer to, a kind of anti-coking waste incineration system of the present utility model, the anti-coking waste incineration system is disclosed
Including rotary kiln 10, dual firing chamber 20, device for dragging dregs 30, at least one suction opeing 50, at least one air outlet 60, pipeline 80 and wind
Machine 40, rotary kiln 10 and dual firing chamber 20 connect, and device for dragging dregs 30 is located at the lower section of dual firing chamber 20, and suction opeing 50 is arranged at dual firing chamber
20 side wall is simultaneously close to device for dragging dregs 30, and air outlet 60 is arranged at the side wall of dual firing chamber 20 and is located at the top of suction opeing 50, wind
Machine 40 includes air inlet 41 and gas outlet 42, and pipeline 80 connects suction opeing 50 and air inlet 41 and connects air outlet 60 and gas outlet
42。
In above-described embodiment, start blower fan 40, adjust air quantity, the part combustion product gases of rotary kiln tail end 11 are introduced into two fires
The bottom of room 20, and enter suction opeing 50, at the same time, by rotary kiln tail end 11 fall into device for dragging dregs 30 high-temperature fusion fluid and
The water vapour that incineration residue is produced after being contacted with cooling water is pumped into suction opeing 50, so that the connection of rotary kiln 10 and dual firing chamber 20
The temperature of the lower section in region, the particularly join domain is lifted, and the bar to form coking is deposited so as to eliminate melt flow stream
Part, reduces the generation of coking.For a small amount of coking of generation, by increasing the flow of blower fan 40, more combustion product gases can be drawn
Enter the bottom of dual firing chamber 20, melting, elimination coking, into the flue gas of suction opeing 50, dual firing chamber are entered by pipeline 80 and blower fan 40
20 combustion zones.A kind of anti-coking waste incineration system of the present utility model can be reduced and connected between rotary kiln tail end 11 and dual firing chamber 20
The coking amount of the burning blind area below region is connect, so that low cost efficiently reduces coking amount, manual maintenance, equipment energy consumption is reduced
Standby cost, does not interfere with the accuracy of observation panel observation and hygrosensor measurement.
In this example, above-mentioned anti-coking waste incineration system also includes being arranged at the pipe expansion device 81 of pipeline 80, its work
With being for compensating the deformation that expanding with heat and contract with cold of producing causes by temperature change of pipeline 80.Pipe expansion device 81 has many realities
Mode is applied, such as pipe expansion device 81 can be expansion joint or compensator.
The anti-coking waste incineration system includes baffle plate 70, and the baffle plate 70 is arranged at the side wall of dual firing chamber 20, particularly
On the side wall 21 of dual firing chamber 20 and positioned at the upper end of suction opeing 50.Baffle plate 70 may be configured as and side wall into certain inclination angle
Degree, so in order to melt flow stream can under gravity along the side wall of dual firing chamber 20 and the top of baffle plate 70 successfully slide to
Device for dragging dregs 30.The benefit of the baffle plate 70, mainly avoids melt flow stream from entering suction opeing 50, and then block suction opeing 50.By
In the effect of baffle plate 70, melt flow stream is fallen a little has predetermined distance to side wall, when melt flow stream is fallen will not hanging fascia in side wall
On.
The blower fan 40 is high-temperature blower, can so have longer service life.Here high-temperature blower 40 refers in height
The blower fan of warm operation, the temperature of its high-temperature operation can be 200 DEG C ~ 1100 DEG C.
The suction opeing 50 is multiple, and is separated between two, and anti-coking waste incineration system includes fan housing, multiple
Suction opeing 50 is connected by fan housing with pipeline 80.The quantity of the suction opeing 50 is according to the coking situation of dual firing chamber 20 and dual firing chamber
Depending on 20 cavity sizes.The suction opeing 50 is arranged on the side wall of dual firing chamber 20 immediately below baffle plate 70, and being arranged at this position can
Extracted by suction opeing 50 with by the water vapour of the upward loss of device for dragging dregs 30, and can be by the especially flue gas of the flue gas in this space
Zhong bioxin noxious material and heat are pumped to the combustion zone of dual firing chamber 20 by suction opeing 50, blower fan 40, pipeline 80, reach environmental protection
The effect of energy-conservation.
The inwall of pipeline 80 is lined with refractory material.For high-temperature flue gas in resistance to pipeline 80.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, although with reference to preceding
State embodiment to be described in detail the utility model, for a person skilled in the art, it still can be to preceding
State the technical scheme described in each embodiment to modify, or equivalent is carried out to which part technical characteristic, it is all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
