Description

Seconday self-combusting incinerator for garbage

The invention belongs to environmental protection equipment, a kind of secondary self-burning type refuse incinerator.

In the environmental protection utility, effective processing of house refuse is one of important problem.For a long time, take always to be transported to that bury in the countryside or air storage is rotted or open incineration naturally for the processing of rubbish, therefore very easily cause environmental pollution, and also need lot of manpower and material resources and high freight.In the recent period, people are exploring the various forms of incinerators of exploitation.But existing incinerator major part all exists complex structure, expends fuel, operating cost is higher, burning causes weak points such as new pollution inadequately fully easily to atmosphere.Patent documentation and consult interrelated data and still find no same or analogous record by retrieval with the present invention.

The purpose of this invention is to provide a kind of rational in infrastructure, make full use of waste heat, once do not need postcombustion, the secondary self-burning type refuse incinerator that firing efficiency is high after the igniting.

The present invention realizes as follows:

The secondary self-burning type refuse incinerator, mainly by external furnace body, heat-insulation layer, composition such as Burning Room and heat-exchanging chamber, external furnace body 1 inside is provided with Burning Room 4, fire grate 24 and travel(l)ing grate 25 are equipped with in Burning Room inner casing 23 inside, the outer cover of Burning Room inner casing 23 is equipped with Burning Room shell 3, use blast pipe 5 respectively between Burning Room shell 3 and the heat-exchanging chamber shell 9, smoke exhaust pipe 6 and blast pipe 20 are connected, smoke pipe bundle 8 is housed in heat-exchanging chamber shell 9, blast pipe 18 and smoke exhaust pipe 17 are housed between heat-exchanging chamber shell 9 and heat-exchanging chamber shell 10, smoke pipe bundle 11 is housed in the heat-exchanging chamber shell 10, smoke exhaust pipe 12 and blast pipe 13 are housed between heat-exchanging chamber shell 10 and heat-exchanging chamber shell 15, smoke pipe bundle 14 is housed in the heat-exchanging chamber shell 15, in the right side of heat-exchanging chamber shell 15 lower rear smoke exhaust pipe 16 and blast pipe 29 are housed respectively, at heat-exchanging chamber shell 9,10, be provided with six groups of heat exchangers 7 that are connected in series connection mutually respectively in six heat exchangers 19 of upper and lower setting in 15, on the upper left side of external furnace body 1 feed appliance shell 28 is housed, feed appliance shell 28 tops and inside are equipped with feed hopper 33 and feeding screw 27 respectively, in the slag notch 22 that Burning Room base 21 middle parts are provided with, spiral slag tapping equipment 32 is housed, drainpipe 30 is contained in the lower right of heat-exchanging chamber shell 15, and the space outerpace with Burning Room shell and each heat-exchanging chamber shell in the external furnace body 1 is filled with heat-insulation layer 2.Burning Room inner casing 23 is to combine with four sections refractory material prefabricated components.Be respectively equipped with one group of moving tooth on the every skeleton of travel(l)ing grate 25.

Advantage of the present invention is: energy savings, once do not need postcombustion again after the igniting, and waste heat is fully recycled, the firing efficiency height.

Fig. 1 is a sectional structure schematic diagram of the present invention;

Fig. 2 is that A-A of the present invention is to the sectional structure schematic diagram;

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

The secondary self-burning type refuse incinerator, external furnace body 1 is to make with sheet metal, and Burning Room inner casing 23 is to be assembled into one by four sections refractory material prefabricated components, and each section seam crossing is filled with fire clay.Burning Room shell 3 can with metal material make and and inner casing 23 assembling after make the cavity that forms three air intakes, smoke evacuation, air intake between the inside and outside shell.The two ends of

smoke pipe bundle

8,11,14 are respectively equipped with the packing plate so that cigarette road and wind path are separated.Each smoke exhaust pipe, blast pipe and heat exchanger are installed external furnace body 1 after connecting again, then with the loam cake of sealing body of heater 1 behind the insulation material filling heat-insulation layer 2.Air blast is installed at blast pipe 29 places, is communicated with at smoke exhaust pipe 16 places installation air-introduced machine and with chimney.Feeding screw 27, travel(l)ing grate 25 and spiral slag tapping equipment 32 are all used motor and deceleration device transmission.During work, fuel and ignition substance are contained on the fire grate 24, rubbish are sent in the Burning Room 4 through feed hopper 33 and feeding screw 27 by the Burning Room fire door.After the igniting, close fire door and start air blast and air-introduced machine.Flue gas through each pipeline of smoke exhaust pipe 6 and each smoke pipe bundle after smoke exhaust pipe 16 is sent into chimney by air-introduced machine discharges.Simultaneously, by air blast with air on blast pipe 29 and each smoke pipe bundle, the space of each pipeline between the lower seal dividing plate and each blast pipe are blown in the Burning Room, space between the shell, thereby the air inlet 26 that the air that is blown into by blast pipe 5 is provided with in Burning Room is blown into and makes rubbish quicken drying in the Burning Room, the air inlet of air through Burning Room inner casing bottom that is blown into by blast pipe 20 is blown into the below of fire grate 24 and plays combustion-supporting effect, between fire grate 24 and travel(l)ing grate 25, belong to the high-temperature region, flue gas can make its contained carbon granules fully burn through the high-temperature region again when discharging, and therefore makes the complete allow compliance with emission standards of flue gas of discharge.Travel(l)ing grate 25 rotates under the motor transmission lentamente, and the moving tooth on each skeleton is constantly dialled rubbish to the high-temperature region of fire grate top and made its second-time burning, therefore, has improved firing efficiency widely.Incinerator when work flue gas has higher temperature, can make each heat exchanger have higher temperature, and the output pipe of heat exchanger is connected to heating plant or bathing pool, has effectively utilized waste heat, has saved the energy.The furnace bottom scarfing cinder can be revolved slag tapping equipment 32 and carries out with removing, and removes the intrafascicular incrustation of each smoke pipe and can open regenerator volume's door 31 and carry out in regenerator volume, can discharge condensed water in the flue gas at any time through the draining valve of drainpipe 30.
