Description

Strong thermal circulation self-burning refuse incinerator

The utility model belongs to environmental protection equipment, a kind of forced heat-circulation self-burning type refuse incinerator.

Effective processing of house refuse is one of important topic in the environmental protection utility; traditional air storage rubbish, bury or on-site incineration rubbish can not satisfy at present to environmental protection requirement; both cause new environmental pollution easily, needed lot of manpower and material resources and high freight again.For this reason, people explore the various forms of garbage combustion devices of exploitation constantly.Existing garbage combustion device major part exists complex structure, expends fuel, operating cost is higher, and burning inadequately fully and easily atmosphere is caused new weak points such as pollution.Through consulting interrelated data and patent searching document, still find no the record identical with the utility model.

The purpose of this utility model provide a kind of make full use of waste heat, powerful thermal cycle, predrying, once do not need again the forced heat-circulation self-burning type refuse incinerator of postcombustion after the igniting.

The utility model is realized as follows:

Forced heat-circulation self-burning type refuse incinerator, formed by incinerator and heat-exchanger rig, the top of the base 21 of incinerator is provided with burns body of heater 4, the top left part is provided with hothouse 2 in the body of heater 4, feeding belt 3 is housed in the hothouse 2, right part is provided with Burning Room 6 in the body of heater 4, travel(l)ing grate 7 and travelling grate 8 are housed in Burning Room 6, scummer 20 is housed in the ash chamber below Burning Room 6, the two ends of warm-air pipe 5 are connected with hothouse 2 and Burning Room 6 respectively, and the outside of warm-air pipe 5 coats with insulation material; The top of heat-exchanger rig base 18 is provided with shell 10, be provided with smoke pipe bundle 11,12,13,14 in shell 10 inside, the bottom is provided with the molten device 17 of carrying liquid, smoke exhaust pipe 15 and blast pipe 16 are housed on the right side wall of shell 10, smoke exhaust pipe 9 and ajutage 19 are housed between body of heater 4 and shell 10, the outside of smoke exhaust pipe 9 and ajutage 19 coats with insulation material respectively, and feed hopper 1 is located at the top of body of heater 4.Be equipped with one group of moving tooth on the every skeleton of travel(l)ing grate 7.Be respectively equipped with moving tooth on the every comb bone of travelling grate 8.The upper and lower of smoke pipe bundle 11,12,13,14 is respectively equipped with the packing plate.

The utility model has the advantages that: do not need postcombustion again after the igniting operation, energy savings, the waste heat that utilization is reclaimed is garbage drying in advance, has improved firing efficiency, and smoke medicining dust-removing effect is remarkable.

Fig. 1 is that master of the present utility model looks and cuts open schematic diagram;

Fig. 2 is the cross-sectional schematic of overlooking of the present utility model.

Introduce most preferred embodiment of the present utility model with reference to the accompanying drawings in detail:

Forced heat-circulation self-burning type refuse incinerator, base 21 can be used reinforced concrete prefabricated moulding, burning body of heater 4 above base 21 can be built into refractory material prefabricated component assembled formation or with refractory brick, and hothouse 2 bottoms are provided with bracket and are supported on the base 21 with support column.Feeding belt 3, travel(l)ing grate 7, travelling grate 8 and scummer 20 all pass through the transmission device transmission by motor.Heat-exchanger rig shell 10 usefulness refractory brick are built into, inwall can insert sheet metal liner, four groups of smoke pipe bundle difference welding-ons are to upper and lower packing plate, above last packing plate, be provided with two demarcation strips, between four groups of smoke pipe bundles between the upper and lower packing plate, be respectively arranged with three semi-enclosed plate washers.Molten device 17 is to make with corrosion resistant metal material, and the bottom of molten device is provided with two valves.Smoke exhaust pipe 15 links to each other with smoke exhaust fan, and air intake wind 6 is connected with air blast.The fire grate top is equipped with during work, ignition substance and fuel.Rubbish is sent in the hothouse 2 and fallen on the feeding belt 3 through feed hopper 1, feeding belt 3 is being sent rubbish into Burning Room in the rotation process lentamente.After the igniting, start air blast and smoke exhaust fan, flue gas enters in the pipeline and by the below and discharges through smoke exhaust pipe 9, smoke pipe bundle 11 tops, enter in the pipeline and through smoke pipe bundle 12 belows again and discharge from the top, enter then in the pipeline of smoke pipe bundle 13, enter in the pipeline through the below of smoke pipe bundle 14, the top by pipeline enters in the smoke exhaust pipe 15 more again, and is discharged by smoke exhaust fan and chimney.Simultaneously, be blown in the Burning Room with the space of each pipeline of air between blast pipe 16 and the upper and lower packing plate of each smoke pipe bundle and through ajutage 19 by air blast, because air is heated when the space of each pipeline of process smoke pipe bundle, thereby formation hot blast, a part plays combustion-supporting effect after being blown in the Burning Room, another part hot blast is in warm-air pipe 5 is blown into hothouse 2, rubbish on the feeding belt is played desiccation, the water vapour that produces during garbage drying is discharged by smoke exhaust pipe 9, be inhaled in the smoke exhaust pipe for fear of rubbish, therefore the right part at hothouse is provided with a filter screen.Because when work, flue gas had higher temperature, therefore, when flue gas makes its vaporization when each smoke pipe bundle touches liquid in the molten device 17, thereby can make contained little carbon granules of flue gas or dust fall into the effect that molten device plays dedusting.When adopting chemical pretreatment solution again can in and contained pernicious gas in the flue gas, to reach the purpose of smoke abatement and dust control, make the flue gas of discharge reach discharge standard, to satisfy the requirement of environmental protection.Heat-exchanger rig also can be used for all kinds of boilers, only needs smoke exhaust pipe 9 is docked with the boiler exhaust gas pipe, and ajutage 19 is connected in the boiler furnace, can play the remarkable result of smoke abatement and dust control equally.Because its simple structure, comparing with the device for eliminating smoke and dust of other class has very significant superiority.
