Abstract

The utility model relates to a garbage incineration furnace, which comprises a garbage inlet and an exhausting port, wherein the centre of a furnace body is provided with a screw propelling type feeding screw rod; the front end of the furnace body is connected with a high temperature fume gas pipe; a temperature probe is arranged on the upper part of the burning point in a boiler. The utility model can control the rotation of the feeding screw rod and the air exhausting strength of an exhausting fan in the furnace body according to the upward and downward movable situations of the burning point. Thus, the burning point can be kept on a fixing position for burning. The garbage incineration furnace has the advantages of simple structure, easy manufacture, no losses, no problems of special materials, easy control of the burning point, stable burning effect, high efficiency and low cost. Besides, the utility model has a strong drying effect on garbage and can make poisonous gases fully decomposed.

Description

Incinerator

The utility model relates to a kind of incinerator.

Existing incinerator is grate-type (Martin furnace) and rotary kiln type (rotary drum furnace), this dual mode all is that rubbish is directly burnt, promptly to light hurrock traditionally as broad as long with people, only be to have increased that rubbish is carried out air blast is combustion-supporting and rubbish carried out ceaselessly to stir it is fully burnt, the defective of this dual mode is: one, rubbish can not guarantee 100% ground completing combustion; Two, incineration firing speed is slow, has limited usage ratio of equipment; Three, moving component is many in the furnace high-temperature district, causes the workmanship to equipment to require height, equipment maintenance cost and loss height; Four, one-time investment is big.

The purpose of this utility model is to provide a kind of incinerator, and this incinerator can overcome the shortcoming of prior art, and its principle and mode are similar to the principle of the cigarette of enfleuraging.

The purpose of this utility model is to realize like this, construct a kind of incinerator, the tail end that it is characterized in that body of heater is equipped with garbage inlet and bleeding point, there is screw-pushing type feed sieve bar in body of heater central authorities, its blade is a hollow out, what link to each other with the front end of body of heater is the high-temperature flue gas pipe, be screw type, it is the extension of body of heater, its diameter that spirals is identical with the diameter of body of heater, and one end and bleeding point link, and the other end hovers above the burning-point place, boiler covers on the burning-point top, and temp probe is positioned at boiler burning-point top.

Incinerator of the present utility model, its feature also are, described incinerator, and garbage inlet is made up of rubbish hopper and circular blanking barrel, and a horizontal movable type blanking and air isolating baffle are arranged between the two, and garbage inlet is vertical with body of heater; There is a filter bleeding point and body of heater junction, and the below of body of heater is provided with one; The front end of body of heater is bent upwards, and acutangulates with body of heater; Have the air-breathing hole on the boiler, flue gas tap, lime-ash tap.

Implement incinerator of the present utility model, its superiority is as follows:

1, simple in structure, be easy to make;

2, do not have moving component in the high-temperature region, do not have the problem of loss and special material;

3, the burning-point situation is easy to control, flameholding, and can guarantee the burning of 100% ground;

4, the thermal current that extracts from burning-point will have very strong roars of laughter to do effect to rubbish by the rubbish of back;

5, the flue gas of extracting out from the afterbody high-temperature flue gas pipe of sending into burning-point carries out pyrolytic, discharges then, enters boiler furnace, carries out pyrolytic once more, thereby fully guarantees the decomposition of toxic gas in high temperature;

6, cost is lower than grate-type and drum-type incinerator, is specially adapted to the processing of the flammable house refuse in general city.

In conjunction with the accompanying drawings and embodiments, further specify characteristics of the present utility model, in the accompanying drawing:

Fig. 1 is the structural representation of the utility model incinerator.

In Fig. 1, incinerator of the present utility model comprises garbage inlet 1, bleeding point 5, body of heater 9, screw-pushing type feed sieve bar 7, high-temperature flue gas pipe 11, boiler 12, temp probe 13 compositions.Garbage inlet 1 is made up of rubbish hopper 4 and circular blanking barrel 2 perpendicular to the tail end of body of heater 9, and a horizontal movable type blanking and air isolating baffle 3 are arranged between rubbish hopper 4 and circular blanking barrel 2.Bleeding point 5 is positioned at watch box 9 tail ends, with body of heater 9 junctions one filter 6 is arranged.One screw-pushing type feed sieve bar 7 is arranged in the body of heater 9, and the blade 8 of sieve bar 7 is netted.Feed sieve bar 7 is connected with electric rotating machine.Rubbish is sent into rubbish hopper 4 by belt, open blanking and air isolating baffle 3, rubbish falls in the incinerator, feed sieve bar 7 in the rotary furnace, rubbish is pushed into the place ahead, feed sieve bar 7 and blanking and 3 interlocks of air isolating baffle, to guarantee at feed sieve bar 7 through rotating several times, blanking and air isolating baffle 3 could be opened once more after rubbish all entered in the body of heater 9, allowed rubbish to fall, but and secluding air.Because body of heater 9 is horizontal, so the rubbish distribution is uneven in the stove, the first half is thinner, and Lower Half is closeer.The front end of body of heater 9 is bent upwards, with 9 one-tenth 75 °-80 ° of bodies of heater, so at sweep to furnace roof portion, it is uniformly that rubbish distributes, and evenly supplies to guarantee burning-point place rubbish, guarantees that burning-point is stable.The fragment of brick of sneaking in the body of heater, glass can be accumulated in the sweep of body of heater 9, for discharging this part non-flammable heavier refuse, have designed a door 10 in body of heater 9 bottoms, remove non-flammable heavier refuses such as fragment of brick, glass.What link to each other with the front end of body of heater 9 is high-temperature flue gas pipe 11, be screw type, it is the extension of body of heater 9, its diameter that spirals is identical with the diameter of body of heater 9, the one end links to each other with bleeding point 5, to send into high-temperature flue gas pipe 11 from the flue gas that bleeding point 5 is extracted out and carry out pyrolytic, the hot gas of extraction also can be dried the rubbish in the body of heater 9; The other end hovers above the burning-point place, the flue gas after decomposing is sent into boiler 12 burner hearths decompose once more.Boiler 12 covers on the burning-point top, temp probe 13 is positioned at boiler 12 burning-points top, and temp probe 13 is controlled the rotation of feed sieve bars 7 in the body of heater 9 according to the upper and lower mobile situation of burning-point, and the bleed exhausting dynamics of blower fan of control frequency conversion, make burning-point remain at fixed position burning.Have air-breathing hole 14 on the boiler, flue gas tap 15, lime-ash tap 16.
