Below, with reference to drawings and Examples characteristics of the present utility model are described:

As shown in Figure 1, be incinerator generalized section of the present utility model, this incinerator 1 includes diapire face 11, the side wall portion made from refractory thermal insulating material 12, and goes up facial 13.Side wall portion 12 is provided with ash discharging hole 121, is provided with steam generator 131, air inlet port 132 and discarded object input port 133 and go up facial 13, and discarded object input port 133 end faces are provided with lid 134.

The bottom wall portion 11 of incinerator and side wall portion 12 are made with refractory material, use any material of ability incinerator internal combustion temperature make can, better with refractory brick as this refractory thermal insulating material; For example filling heat-resisting guarantor's hot material between inside and outside layer steel plate wall also can.

On the incinerator facial 13 set discarded object input ports 133 and on the lid of establishing 134 that covers be discarded object to be devoted in the incinerator in fed batch (Batch) mode.Lid 134 is not particularly limited, is installed in face 13 on the incinerator 1 in spring (Spring) mode, and covers on discarded object input port 133 at any time, make it possess the function that safety valve is arranged and be ideal.Face 13 on the incinerator, set one or several air inlet ports 132, it is for introducing outside air, and to help waste combustion in the stove, this air inlet port can be the perforate of Any shape, also suitable control valve 135 can be installed, to regulate air mass flow.

But at the ash discharging hole 121 outside install combustion machines (not shown) of incinerator 1 side wall portion 12, auxiliary combustion is used when being difficult for spontaneous combustion when lighting a fire as incinerator.

Incinerator 1 lower part (that is bottom wall portion 11 tops) is equipped with fire resistance gravel layer 2, this gravel adopts for example brick, rubble, other refractory material crushed material etc., and the formation of this gravel layer 2, for example shown in Figure 1, be in furnace bottom part directly or with suitable holder between the centre and the gravel 21 of the about 50-70mm of filling external diameter is the lamination shape.These fire resistance gravel layer 2 replacements are also finished the function of incinerator grate (Rostor) in the past, and it is easier than the common grate maintenance of steel commonly used, guarantor's thermal effect is arranged again, that is, when burning (burning) in the fed batch mode continuously, be transformed into when feeding intake, because of in gravel layer 2, still keeping the waste heat of former burning from once feeding intake next time, making feeds intake next time is easier to take fire, and promotes its combustion efficiency significantly.

Moreover, according to the utility model, in fire resistance gravel layer 2 inside (as shown in Figure 1) or below this fire resistance gravel layer (not shown), support refractory brick to make according to two ends and keep being installed on air and steam supply pipe 3 horizontally, this supply pipe 3 offers several perforates that Open Side Down 31, and air and steam are supplied in the stove equably.

Supply for air and steam, for example shown in Figure 1, also pass through the flow-control of control valve 43 and 44 respectively via pipe arrangement 41 and 42, and respectively outside air a and steam b are supplied in the stove via above-mentioned air and steam supply pipe 3, make the interior temperature of stove remain in institute's definite value.The furnace wall of incinerator 1 for example side wall portion is provided with temperature sensor (Senser) 45, can detect temperature in the stove, temperature sensor 45 connects a controller 46, reconnects and states control valve 43 and 44, use control air and steam flow, and implement temperature control in the stove.Temperature can be changed according to the discarded object kind in the desirable stove, is maximum temperature with about 1,200 ℃ usually, and the utility model is controlled to be 500-1000 ℃.

The utility model can suitably change the aperture area of the perforate 31 of air and steam supply pipe 3, can be 50～90% of pipe 3 basal areas.With 70～80% serves as suitable.Air is not particularly limited with the supply ratio of steam, controls (Control) control valve 43 and 44 aptly, can be so that temperature remains required numerical value in the stove.

The above-mentioned steam of supplying from the external world is in air and steam supply pipe 3, for example shown in Figure 1, the facial 13 inner steam generators 131 that filling water is installed on stove 1, according to burning the combustion heat that is produced in the stove, can make generator 131 produce steam, and be supplied in the furnace bottom part, according to this design, can be from extraneous air supply steam, and have self-sustainable advantage in the native system.

Incinerator 1 is provided with the filter screen 141 that available stainless steel is made therebetween in being provided with exhaust outlet (chimney) 14 near last facial 13, one sides.In incinerator 1, burn the solids carried secretly in the discarded object produced and can be stopped and shake off that remaining is discarded then from exhaust outlet 14 by filter screen 141 in furnace bottom; Discharge in atmosphere.Can form the second burning area 142 in filter screen 141 downstreams, and the setting of energy air supply and steam is arranged, and it is burnt again, make discarded object pollution-free.

In addition, be provided with igniter 15 at the side wall portion of stove, can be from extraneous air a and the igniting fuel C introduced, as initial stage igniting usefulness.

In addition, as shown in Figure 2, be provided with forced air supply machine 5, send in the stove, it is circled round in stove and increase the time of staying, make that discarded object more can completing combustion via the ajutage forced air supply and with tangential direction in the side wall portion of stove.Moreover, be provided with cyclone 6 in chimney 14 bottoms, make and can give effective collection by the lighter dust that produces when for example burning stationery; Be equipped with at chimney again on the one hand and force exhaust blower 7,, make the stove inner combustion chamber keep negative pressure with auxiliary exhaust.

According to the utility model,, must adjust necessary air capacity and temperature to every kind of discarded object in order to burn various discarded objects fully smokelessly.If suitably do not adjust temperature, particularly when burning plastics, when improving temperature excessively, its also simultaneously dissolving, do not aerify, can not completing combustion.

Incinerator does not in the past generally all adopt temperature to adjust measure, at most only increases and decreases the discarded object input amount or adjusts air capacity, and it can not regulate incineration temperature.To this, the utility model injects steam in the air of being supplied with for complying with, or except air supply, the steam that also supplies water simultaneously in addition is with the control incineration temperature.That is temperature rises when too much (more than 1000 ℃ time), increases the steam quantity delivered; And descend when too much when temperature, then reduce the steam quantity delivered, according to this, control temperature effectively.

Can make water replace steam, but this moment is big because of evaporation of water latent heat, difficult control ignition temperature, therefore not satisfactory.

For the supply of steam, can adopt steam that incinerator itself produced or from other local steam that imports.As the control mode of control supply steam vapour amount and air capacity, with the automatic control mode of manual control mode or employing automatic controls, the latter can seek higher operating efficiency.

Use the effect of steam to be, except above-mentioned, when burning to 1000 ℃, it can produce water-based gas (gas) with the carbon reaction, and this helps further burning.

As above explanation, the utility model adopt the mode of steam control temperature when burning paper, organic waste and plastics the like waste, can control ignition temperature; Again when temperature in the stove be more than 1000 ℃ the time, steam and carbon reaction produce water-based gas, also can promote burning sometimes, therefore can burn aforementioned various discarded object fully, make it nuisanceless.

In sum, incinerator of the present utility model is a kind of incinerator of regulating ignition temperature, has stronger practicality.
