Thorax 3, burner hearth 3 can be the rotational-like of cylinder, can also be in the rotational-like of certain taper, the cross section of burner hearth 3 is in circle
Shape；Incinerator is fixedly mounted, and burner hearth center line 100 is horizontal linear, and burner hearth 3 includes the drying section 1 being docking together and burning
The burner hearth 3 of drying section 1 and burning zone 2, can be disposed as cylindrical shape, and in the burner hearth 3 of drying section 1 and burning zone 2 by section 2
Diameter is equal, and at least one tangential air port 5 is respectively provided on the side wall of drying section 1 and burning zone 2, and tangential air port 5 passes through tangential air duct 4
It is connected with air blower 6, the air-out direction in tangential air port 5 and the inner wall circumference of burner hearth 3 are tangent, and are deflected to the tail portion of burner hearth 3；This
Sample, the wind blown out from air blower 6 can form spiral wind path 12 after entering burner hearth 3 by the tangential air port 5 in tangential air duct 4, along stove
3 inner wall of thorax advances to 3 tail portion helical form of burner hearth, and the wind flowed along spiral wind path 12 occurs turbulence effect and forms powerful turbulent flow spiral shell
Whirlwind.In burning waste, the combustible waste material of broken shape enters burner hearth 3 from drying section 1, and drying section 1 receives to pass from burning zone 2
The heat passed, the combustible waste material for being sent into drying section 1 dispels mixing by powerful turbulent flow spiral wind, broken in drying section 1
Shape waste is dried into that (main component of flue gas is CO, H for dry and loose combustibles and the flue gas thermally decomposed2,
CH2, CO2Deng and concentration denier C12H4Cl4O2), and be suspended in burner hearth 3 with turbulent flow spiral wind, continue surely for waste
Fixed burning creates good condition；Broken shape waste is blown to burning zone 2 under the action of powerful turbulent flow spiral wind；In burning zone
In 2, the broken shape waste being oven-dried is thoroughly mixed and burns under the action of turbulent flow spiral wind, and by powerful turbulent flow spiral wind
It blows to stove last row to go out, turbulent combustion mode can make flame fast propagation.So a kind of horizontal incinerator of the invention,
Waste is pushed using powerful turbulent flow spiral wind, is not necessarily to the mechanical transmission of complex and expensive, powerful turbulent flow spiral whirlwind
Integrate and stir, put a chimney on the stove and make the fire draw, stirring, oxygenation, mixing, promote burning, extend the multiple functions such as residence time, using turbulent flow spiral
Wind is conducive to burning, substitutes machine driving acting with wind, powerful turbulent flow spiral wind can help waste and air in stove abundant
Mixing is in favor of dry and burning；Thus a kind of horizontal incinerator of the present invention is simple in structure, operation is convenient, at low cost
It is honest and clean.
For the ease of the installation and maintenance in the tangential air duct 4 of incinerator, tangential air port 5, air blower 6, as shown in Fig. 2, can
It, in this way being horizontally mounted basis and install 6 He of air blower using scene being arranged in tangential air duct 4 in the bottom of burner hearth 3
Tangential air duct 4, when repair, are also more convenient.Meanwhile the upward powerful air-flow blown out from tangential air port 5, be conducive to fall in stove
The waste of thorax bottom obtains initial kinetic energy, and screw is formed with air-flow.Certainly, the erecting bed of different user, peace
Dress basis may differ widely, and circumferential position of the tangential air port 5 on 3 side wall of burner hearth can be adjusted according to field condition,
Each tangential air port 5 can be even arranged in the circumferential different location of burner hearth 3.
As shown in Figure 1, for the ease of the manufacture of incinerator, the furnace body of incinerator can be fabricated to two sections, two-stage furnace body
Between can be connected with, two-stage furnace body has the equal and cylindrical burner hearth 3 of internal diameter, and the docking of two-stage furnace body is made two sections
The burner hearth 3 of furnace body coaxially docks；It is equipped with feeder 8 in the entrance of drying section 1, feeder 8 includes hopper 81, for the ease of
The amount for controlling feeding, into burner hearth 3, timing quantitatively uniform feeding, may be used the feeder 8 with function of measuring；It is drying
Position in section 1, close to burning zone 2 is equipped with burner connecting tube 11, the outlet of burner connecting tube 11 towards burning zone 2,
When starting the horizontal incinerator burning waste of the present invention, it is logical to 2 burner hearth 3 of burning zone to first pass through burner connecting tube 11
Enter the burner hearth 3 of flame heating burning zone 2；In order to enable flame heat burn section burner hearth 3 suitable position and can be in burning zone 2
It is uniformly spread in burner hearth 3, the angle β sizes between the outlet and burner hearth center line 100 of burner connecting tube 11 properly will such as be schemed
Shown in 3, the center line of burner connecting tube 11 and the angle β of burner hearth center line 100 are preferably 45 degree.Because waste is burning
Section 2 is burnt, and amount of heat is generated, and since waste has been subjected to drying in drying section 1, then enters combustion again with turbulent flow pattern
Section 2 is burnt, so being readily formed stable burning, after stablizing burning, the present invention just no longer needs to the flame by burner.Burning
3 inner wall of burner hearth of section 2 will be made of refractory material, and 3 inner wall of burner hearth refractory material laying has that amount of stored heat is big, the heat accumulation time
Advantage long, temperature is high, can make to keep high temperature for a long time in burner hearth 3.Due to having built fire resisting by laying bricks or stones on the inner wall of burning zone 2
Material, therefore the outer diameter of burning zone 2 is larger than the outer diameter of drying section 1.
The angle that the air-out direction in tangential air port 5 is deflected to 3 tail portion of burner hearth is bigger, then the wind direction blown out from tangential air port 5
The speed that 3 tail portion of burner hearth is threadingly advanced will be faster, but the number of turns that wind is rotated along 3 spiral inner wall of burner hearth will be less, such
Turbulence effects are just not good enough, and waste residence time in stove is shorter, and burning is insufficient；If on the contrary, the outlet air in tangential air port 5
The angle that direction is deflected to 3 tail portion of burner hearth is smaller, the number of turns meeting that the wind blown out from tangential air port 5 is rotated along 3 spiral inner wall of burner hearth
It is more, but the speed that 3 tail portion of wind direction burner hearth is threadingly advanced will be slower, and the efficiency of burning is lower.So tangential air port 5
The angle that air-out direction is deflected to 3 tail portion of burner hearth will be in suitable range, by verification, and the air-out direction in tangential air port 5 is to stove
When the angle [alpha] of 3 tail portion of thorax deflection is spent for 10-30, preferable turbulivity can guarantee, and waste can be made to be stopped in stove enough
Time, when this angle [alpha] is spent for 10-15, best results, the turbulent flow spiral wind that each tangential air port 5 is blown out was along wide fully to burn
Degree direction can mutually cover, and the inner wall of entire burner hearth 3 is made to be covered with turbulent flow spiral wind, and burning is more abundant.Drying section 1 and burning
Spacing on the side wall of section 2 between the quantity and each tangential air port 5 in tangential air duct 4, tangential air port 5 and air blower 6 is according to burner hearth 3
Each section sets turbulivity and wind along the needs of the axial speed of service of burner hearth 3, the length of burner hearth 3 and 3 internal diameter of burner hearth, each tangential
Spacing between air port 5 can be equal, can not also be equal；3 length of burner hearth is longer, internal diameter is bigger, the tangential air duct 4 that needs,
The quantity of tangential air port 5 and air blower 6 is more, and the enough rapidss of intensity are formed to keep having in burner hearth 3 enough air quantity
Flow spiral wind.Two tangential air ports 5 are arranged in the present embodiment in drying section 1, and, close to feeder 8, another is close for one of them
Burning zone 2；At the intermediate position of burning zone 2, one tangential air port 5 is set.

It is connected by the changeover portion of a cone between the tail portion of burner hearth 3 and stove tail outlet 7, the diameter of stove tail outlet 7 is straight less than burner hearth 3
Diameter, that is to say, that 3 tail diameter size of burner hearth will be shunk；In this way, turbulent flow spiral wind in 3 tail portion contraction place of burner hearth by burner hearth 3
Wall blocking rubs and causes speed that can slow down, and not sufficiently combusted waste can be longer in the 2 tail portion residence time of burning zone, in favor of
The abundant burning of waste.In 2 bottom of burning zone, slag-drip opening 9 is equipped at 3 tail portion of burner hearth, waste is in 2 tail portion of burning zone
Movement velocity slows down, and fully sinks after burning, can be discharged from slag-drip opening 9 by the clinker after waste combustion.From stove
The flue-gas temperature of 7 discharge of tail outlet is very high, can utilize the converting heat that flue gas is discharged, for example can utilize the flue gas of discharge
Heater blower 6 is sent to the air of burner hearth 3；In this way, air blower 6 is blown into hot wind into 1 burner hearth 3 of drying section, more conducively drying is useless
Gurry is also more conducive to improve the temperature of burning zone 2, energy saving.
