Description

Rotary combustion furnace

The utility model is relevant for rotary combustion furnace, is meant it especially by rotary furnace drying, the burning of discarded object being adopted with two-period form, enables to promote the discarded object effect completely of fully being incinerated, burn.

Along with expanding economy, the generation of industrial waste is annual to increase severely in recent years, and how handling this problem has become important problem in fact.Pollution, the kitchen that particularly wherein contains 90% above moisture content is surplus, moist rubbish etc., and it is difficult handling with common incinerator.Therefore with simple low again transshipment charge and the incinerator that can handle many water content organic waste like this by demand.And general its body of heater of helicoid incinerator is all fixed form, when burning waste, a certain amount of discarded object is dropped into discarded object on fire grate, below fire grate, come the moisture content of heating evaporation discarded object with combustor, and with combustor from top burning waste.Treat burned the finishing of discarded object and by ash discharge behind the outside, drop into again that a certain amount of discarded object is continuous does burning.

Above-mentioned existing incinerator is the discarded object above the fire grate to be done dry one side on the one hand with combustor burn from the surface, but the discarded object (as mud) that contains the above person of 90% moisture content has the burning difficulty, and the problem that has transshipment charge to improve.And because just from surface combustion, just can so the inside of discarded object need lean on continuous stirring to stir.Therefore also can cause from the chimney dust that disperses, problem of environment pollution caused takes place.

In view of this, main purpose of the present utility model provides a kind of rotary incinerator that can address the above problem, though for water content up to the discarded object more than 90%, not only can burn easily and transshipment charge low, low in the pollution of the environment, can meet this kind industry demand.

For achieving the above object, the technological means that the utility model is taked mainly is: a kind of rotary combustion furnace consists predominantly of discharging area, rotating furnace body, transmission device, flame combustion machine, dust arrester, heat exchanger, high pressure exhausting filter and removes ash bucket; It is characterized in that: rotating furnace body is two, stacked shape was set up about this two rotating furnace body was, one is the oven dry discarded object, the drying oven that mud is used, another is a combustion furnace, respectively be provided with second channel that supplied gas passes through and the first passage that passes through for dried discarded object before and after two bodies of heater, the flame combustion machine is at least two, be arranged at two rotating furnace bodies, one side respectively, wherein each rotating furnace body outside is provided with a plurality of valves, article at least two, rail bar, the agitator and the spiral pushing plate that have axial setting in inside, the rail bar that is located at the rotating furnace body outside can be rotated with the friction tape flowing mode by transmission device, is provided with the waste material in the body of heater, slag gives scarifying and rotation is carried; Transmission device is two groups also, is arranged at the below of each rotating furnace body, and this group transmission device includes a motor, two rotating shafts, several holders and friction guide wheels; And utilizing the output gear of motor and chain to drive two rotating shafts rotation, the friction guide wheel that is fixed in the rotating shaft that is coupling simultaneously can be rotated by drive in the lump, and the rail bar friction of friction guide wheel driven rotary body of heater is rotated.

Between two rotating shafts of transmission device, have more than one correcting bearing, rotating furnace body is rotated when biased, make the effect of correcting with this correcting bearing at the side of rotating furnace body rail bar setting.

Discharging opening place on the second channel outer wall in two rotating furnace body the place aheads is provided with the adjustment panel, and the flame combustion machine is arranged on this adjustment panel.

This shows, the utility model main feature and effect are: utilize two independent rotating furnace bodies that are provided with are set, wherein be positioned at the rotating furnace body that hot gas that the burning rotating furnace body of lower floor produced can be imported into the upper strata, made earlier the discarded object can be comparatively dry after the scarifying for discarded object, can easily fully be incinerated in the burning rotating furnace body time.Each rotating furnace body is to be built-in with fire-resistant mud layer with inside and outside stainless steel in addition, for making body of heater when high-temp combustion, it is disconnected hot to have wearability and a preferable insulation, and in the process of burning, lysigenous material in some high temperature incineration process of infiltration when not having inboard wall of furnace body and directly adopting fire clay is so can improve the service life of body of heater.And the flame combustion machine is arranged in burning rotating furnace body one side device, and can utilize and adjust the adjustment that panel is made height, enable to cooperate the number of discarded object amount to carry out completing combustion and become ashes.

Further describe the utility model below in conjunction with accompanying drawing.

Shown in Figure 1 is that the utility model is formed construction plan view.

Shown in Figure 2 is the blanking view of the utility model discharging area.

Shown in Figure 3 is the utility model body of heater internal structure partial cross-sectional perspective view.

Shown in Figure 4 is the transmission structures figure of the utility model rotating furnace.

Shown in Figure 5 is the schematic perspective view that the utility model slag discharging place and flame combustion machine are provided with state.

See also Figure 1 and Figure 2, the utility model includes discharging area 1, two rotating furnace bodies 2, two groups of transmission devices 3, at least two tool flame combustion machines 4, dust arrester 5, heat exchanger 6, high pressure exhausting filter 7 reaches and removes ash bucket 8, wherein two rotating furnace bodies 2 of levels respectively are oven dry and burning discarded object usefulness, be provided with one group of transmission device 3 in each body of heater below, discarded object can be sent in the upper strata rotating furnace body 2 with auger conveyor 11 by discharging area 1, these two rotating furnace bodies, 2 rears are communicated with first passage 25, after it can be kept supplying discarded objects in the dry rotating furnace body of layer 2 and does preliminary oven dry and reduce moisture content, discarded object is fallen into earlier in the first passage 25 to be conveyed in lower floor's burning rotating furnace body 2 by auger conveyor 251 again, and be communicated in the second channel 26 in two rotating furnace bodies, 2 the place aheads, can upwards enter in the upper strata rotating furnace body 2 for waste gas, residue then can be sent (as shown in Figure 5) by discharging opening 261 by an auger conveyor, and stores in removing ash bucket 8.
