Abstract
The utility model discloses a medical refuse-burning furnace with an inclined and reciprocated grate with an S-shape furnace tank. The burning course can be mechanized via using the reciprocated grate. The combustible fuel burnt can be pre-heated and added new refuse after being ignited. The dust which is not yet burnt and the smoke gas separating inside the furnace are re-ignited with employing the S-shape furnace tank. The turning positions of the front arch and the rear arch are provided with tertiary air holes and auxiliary air holes respectively, and the air quantity offered can not only disturb the enhancement and mixture of the smoke gas but also guarantee property of the excess air coefficient, thereby burning completely and reducing the harmful materials. The thickness of the discharging is lower than the need of the environment protection. An air heater is provided in the rear portion, thereby lowering the temperature of smoke discharging. The utility model returns the heat and is novel in structure, low in price and reliable in operation.
Description
The utility model relates to a kind of incinerator, particularly relates to a kind of inclined reciprocating fire grate " S " type burner hearth incinerator for medical garbage.
It is domestic that still to remain the height of fixedly siege incinerator, burner hearth at the incinerator for medical garbage of a large amount of operations now low and be straight barrel type.Do not have secondary wind to carry out disturbance, flue gas and the combustion product time of staying weak point in stove, produced a large amount of imperfect combustion products and pernicious gas dioxin, its dust exhausting concentration is up to 200mg/Nm behind dry collector
3More than, thereby cause secondary pollution, pollute as hot-air, all above the requirement of environmental protection standard, in addition, its afterbody all is unkitted the heating surface that absorbs heat for smoke contamination and dioxin contamination etc., cause exhaust gas temperature up to more than 500 ℃, increased environmental pollution and energy waste.
At the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of like this inclined reciprocating fire grate " S " type burner hearth incinerator for medical garbage.Inclined reciprocating fire grate is a kind of combustion apparatus that makes combustion process mechanization, and it is simple in structure, and is easily manufactured.Metal consumption and operating cost are low, smoke effect is preferably arranged again, and employing " S " type burner hearth and the corner feeding tertiary air and the secondary wind that encircle in the front and back that constitute " S " type burner hearth carry out disturbance to combustion product, and it is complete that burning is able to, reduce pollution, improved boiler efficiency.
For achieving the above object, the utility model has been taked following technical measures.
The combustion apparatus of its underpart adopts inclined reciprocating fire grate and by motor drives, hopper is equipped with in the stokehold,
" S " type burner hearth mainly is made of face arch, rear arch and the vertical left and right sides side wall of respective curved, and the corner of front and back arch offers tertiary air hole and secondary air hole respectively, and afterbody is equipped with air preheater, exhanst gas outlet and ash bucket with tipping platform.
Major advantage of the present utility model is as follows:
1, adopts inclined reciprocating fire grate, the combustion process of medical waste is carried out continuously, make medical waste charging in stove continuously, utilize the rubbish that in stove, has burnt that the rubbish that newly inserts is played preheating and the effect of igniting, overcome the pollution that the discontinuity burning causes in startup and furnace shutting down process.Described fire grate is the rear-inclined windward, and front-seat pusher row is higher, and rubbish is pushed on the fire grate from hopper easily.
2, adopt " S " type burner hearth and at the face arch that constitutes " S " type burner hearth, the corner of back confession offers tertiary air hole and secondary air hole respectively, flue gas is in " S " type burner hearth and flue inside turn, grit can be separated the continuation after-flame, flue gas can stop more than 2 seconds in burner hearth, but secondary wind and tertiary air be blown into both disturbances to strengthen in stove and the mixing of combustion product, strengthen the after-flame ability, can control the excess air factor in the stove again, avoid the generation of pernicious gas dioxin, reduced thermal pollution, made the requirement that is lower than national environmental protection by the smoke density of wet scrubber.
3, afterbody has adopted air preheater, has both absorbed used heat, has reduced exhaust gas temperature, has saved the energy, again preheating enter air under the fire grate, improved burning condition.
The utility model is described in further detail below in conjunction with accompanying drawing.
Figure is the structure cross-sectional schematic of the utility model inclined reciprocating fire grate " S " type burner hearth incinerator for medical garbage.
As shown in the figure, the bottom be an inclined reciprocating fire grate 2 and by motor 1 driving, described fire grate 2 is the rear-inclined windward, the stokehold is equipped with hopper 3 and is convenient to continuous feed, big fire door all is equipped with in both sides at furnace wall, be convenient to manually bulk rubbish be dropped into (not shown), " S " type burner hearth 4 is by the face arch 5 of respective curved, rear arch 6 and both walls constitute, preceding corner for 5 has tertiary air hole 8, the corner of rear arch 6 has secondary air hole 7, afterbody is equipped with air preheater 9 successively along the flow of flue gas direction, exhanst gas outlet 10, the bottom is an ash bucket 11 with tipping platform, cleaning door 12 also is housed between the bottom of the rear portion of fire grate 2 and afterbody furnace wall, material that can not after-flame can be removed from this.Be in operation, high-temperature flue gas can be lighted the rubbish that newly inserts from rear arch, to guarantee continuous operation, in " S " type burner hearth 4, its flue gas just can make grit separate in rotation in the uphill process, adds secondary wind and the tertiary air that rear arch and face arch intersection sends and mixes fully and disturbance with combustion product, thereby combustion product is extended at residing time in furnace, help after-flame, improved the efficiency of combustion of boiler, reduced harmful substance.
The utility model novel structure, reliable, but continuous feed, after-flame degree height has reduced the nuisance concentration and the flue-gas temperature of discharging, thereby has improved boiler thermal output.
