Abstract
A comprehensive utilization system for garbage incineration is composed of 4 units: garbage pre-treating unit, pyrogenous gas producing unit, unit for using pyrogenous substance as heat source, and unit for post-treating afterheat gas. Its advantages are reducing cost to minimum, use of all pyrogenous products, and no environmental pollution.
Description
The present invention relates to a kind of waste incineration utilization system, continuous production application carbonizing gas widely in disposal of refuse.
Chinese patent application CN1083198A discloses a kind of " method and apparatus of hot disposal of garbage ".This system equipment is complicated, and low temperature distillation gas and from the less low temperature distillation material of salvage stores separator, is all burnt in the combustion chamber, thereby makes the garbage disposal cost of whole system higher.
The objective of the invention is to overcome the deficiency of prior art and provide a kind of equipment simpler, and can utilize the rubbish pyrolysate, can also produce the system of carbonizing gas in the time of disposal of refuse more economically continuously as the destructive distillation thermal source.
Waste incineration utilization system of the present invention comprises following equipment and operation: a) rubbish pre-treatment: through the screening washer screening, after the dehumidifier dehumidifying, be coiled into drawing mechanism and send into the destructive distillation chamber; B) carbonizing gas production: some groups of destructive distillation chambers are arranged in the burner hearth, and the carbonizing gas that comes out through each mechanical seal is in the pipeline pass-out; C) pyrolysate is made thermal source: the conveyor screw counter-rotating, in due order pyrolysate is entered the pulverizer that corresponding charging/discharging device end opening connects, and powder feeds the burner hearth burning by the powder pipeline; D) waste heat gas post processing: concentrate with blower fan from the unburnt gas of burner hearth to enter the secondary high temperature combustors, the high-temperature gas of generation feeds dehumidifier, and the waste gas after the utilization enters chimney by purifier.Some groups of destructive distillation chambers, mechanical seal, spiral charging/discharging device and pulverizer are arranged in burner hearth, can so that when one group when loading rubbish, producing for several groups in addition, to keep the burner hearth destructive distillation temperature required, guarantee that destructive distillation is so incensed that with without interruption.
System of the present invention advantages of simple can reduce the garbage disposal cost to greatest extent, and the destructive distillation product can all utilize, and in nuisanceless disposal of refuse, also obtains the carbonizing gas of extensive use.
Fig. 1 is a system schematic of the present invention.
The invention will be further described below in conjunction with embodiment.Rubbish is at first poured screening washer 1 into, removes bigger masonry, glass, metallic article etc. and becomes particle.Particle enters dehumidifier 2 dryings subsequently.Siccative is coiled into drawing mechanism 3 and sends into destructive distillation chamber 4.2 destructive distillation chambers are installed in the burner hearth 5, can rotate by the bearing shell in the support of bearing 6 and the mechanical seal 7 separately.The combustion gas body does not feed secondary high temperature combustors 9 from the waste heat gas vent of burner hearth and the waste gas of generating set 11 discharges with blower fan 8 to the greatest extent.Burn coal and start destructive distillation, production temperature in destructive distillation chamber is generally at 300-700 ℃, and carbonizing gas is from connecting the pipeline pass-out of mechanical seal, this example has two pipelines, a 10-1 leads to oil-electric engine group 11, and another 10-2 leads to burner hearth, and it is combustion-supporting to open valve 10-3 when needing.High temperature combustors production temperature is at 1000-1200 ℃, and the high-temperature gas that comes out feeds dehumidifier 2 and carries out heat exchange, is used to garbage drying; Waste gas after the utilization enters chimney 13 at last by purifier 12 and is discharged.
In order to reduce the garbage disposal cost and to make full use of pyrolysate, the present invention is at the charging aperture attaching spiral charging/discharging device 3 of destructive distillation chamber 4, and this device outlet 3-1 down links to each other with pulverizer 14.When destructive distillation was finished, destructive distillation chamber and conveyor screw all reversed, and the destructive distillation material is entered pulverizer, and the powder after the pulverizing sprays into the burner hearth burning by powder pipeline 15.
Slag in burner hearth and the secondary high temperature combustors becomes glassy mass by cold treatment, and it can mix fillers such as cement, mortar and make fragment of brick.The invention enables the rubbish of the system of entering all to be utilized nuisanceless discharging.
