12, the process of waste incineration and corresponding method of operation:

Rubbish must simply sort processing after entering and burning the place, with rejecting such as aphlogistic building waste, glass, cutting metal or screen out.Particularly burn the normal later stage, the broken rubbish that feeds intake is many, to make it pass through sieve plate 9 as far as possible, with the broken last landing of nonflammable rubbish, send into the combustiblerefuse that is in the stove, reduce furnace pressure, make the whole burning phase be in the high-temp combustion state all the time, improve burning velocity and quality, reduce the generation of hydroxide.

And combustiblerefuse also is divided into incendive garbage and than incendive garbage.Before burning, should sort.After the letter sorting, incendive garbage can be used for bottoming and usefulness on fire, and on cast iron grate 16, spread thicker one deck, and then layer overlay then burns from the grate down-firing than incendive garbage.Only in this way, just can have the sufficient fire in a stove before fuel is added to impel than incendive garbage burns.

On fire with the part kindling, on fire after, throw earlier incendive garbage, the burning in early stage must be carried out according to the principle of " the few throwing repeatedly ", and be the where is it incineration firing eat dishes without rice or wine where just throw.Stop to occur empty burner, stop the unnecessary contradiction of lack of air and air and take turns in the combustion chamber to produce, keep the ground burning of whole burning zone stable and uniform.Have only burning uniformly and stably, just form sufficient bottom fire layer in the burner hearth easily, after the fire in a stove before fuel is added forms, just can add and replenish feeding intake according to the feeding mode of " throw few time " more.

The uniform fire in a stove before fuel is added thickness of density is generally 45~55cm (parallel with oxygen increasing tube 14 upper ends), and the air that enters burning zone and rubbish mixed combustion like this from cast iron grate 16 bottoms will pass whole waste layer more equably.

In the early stage of burning, should open with the highly parallel body of heater of cast iron grate 16 door 15 that is cut clearly as far as possible, long as the opening time, two uniform velocity but anisothermal concurrent flow come in contact, and the fire box temperature layer sharply changes, and it is interior persistently overheating to influence burner hearth.

The burning back produces the flue gas of irregular movement, but temperature is higher, under the prerequisite of air-introduced machine 7 forced convections, a large amount of combustible volatile and the flue gas of flue dust is arranged, and is to go up current downflow around rubbish and the irregular housing slit.Like this processing can impel flue gas time of staying of burner hearth within 5~10 seconds.Combustible volatile in the flue gas and dust be just relative lacked many.Progressively become lime-ash to cast iron grate 16 bottom adverse currents after the incendive garbage burning, the irregular stream that thereupon melts downwards in burning back, top, produce the crack, because the temperature of burning back casing is very high, cause burning velocity too fast, flow of flue gas speeds up, thereby can take away a large amount of combustible volatile and dust, at this moment will add incendive garbage as early as possible.

The present invention is provided with two-layer thorax inner flue up and down.Flue gas flings in the dome of upper furnace under the prerequisite of forced convection, the back under the effect of flue gas impact air-flow, with the furnace wall of burner hearth dome rub clocklike roll mobile.Diffusion flow, the viscous stress of the chemical constituent that the concentration gradient of the flue gas that the burning back produces causes, rational and orderly ground floats to the Chu Yanchi of roof of the furnace from the burning zone surface.Under the effect of flue gas buoyance lift and forced convection gravitation, bring flue gas into upper flue 19 by five below the burner hearth dome upper flue gas approach 22 that differ in size.Back flue gas enters flow velocity control member 3 by burner hearth exhanst gas outlet 23 at last by lower flue 18 in three last lower flue through hole 25 input thoraxes that differ in size of upper flue 19 bottoms.The smoke density of upper flue 19 can increase along with constantly flowing like this.Therefore, the temperature in the thorax can not run off owing to spread speed is too fast, and the temperature of burner hearth rises, the stable fire of burning zone, flue gas is also more reasonable in the time of the stop of burner hearth, and flue dust also just reduces relatively.

Have only by such approach conduction flue gas, from burning zone to the smoke density between the flue gas general export, viscous stress and mass diffusion coefficient, just more relatively stable reasonable, open the charging flap, flue gas is well-regulated tumbling motion between the material mouth, do not have to scurry on the flue gas, just belong to normal phenomenon.

After stable flow field forms, the speeding up of burning, the lime-ash of carburization zone also increases thereupon, and constantly molten downwards stream blocks cast iron grate 16 spaces.As untimely logical ash, the additional air in the burner hearth is obstructed, and the influence burning when leading to slag, be noted observing where black just where logical.When leading to slag, find that a large amount of Mars glide, stop logical slag.Impel the air that enters even as far as possible.Because of the character and the water content of rubbish is not quite similar, easily produce coking phenomenon in the warm.Coke button is smashed and go out as the logical pricker of untimely usefulness, can block air equally and enter burning zone and cause producing lack of air and the unnecessary contradiction of air, influence normal combustion from body of heater door 15 hooks that are cut clearly.In burning, observe the intensity of a fire, often stove is picked in scarfing cinder, keeps the interior air of burner hearth unimpeded, increases the contact area of air and rubbish, impels rubbish fully to burn, and reduces nitrogen oxide and produces.The pollution of natural environment largely is because heat transfer and mass transfer are caused.

Go out the flue gas of body of heater, still contained certain flue dust.In order to prevent that flue dust runs off from outlet flue, contaminated environment after control flow velocity flow process, is provided with spraying spraying and dedusting pond, higher-pressure region again, and has controlled the discharging of water.With the water behind the recirculated water spray belong to acid water, carry out chemical reaction so regularly add alkali.Become neutral water.After dust slag that tank 49 precipitates for a long time also regularly takes out, dry and in time send into burner hearth and burn once more, reduce waste gas, contaminated wastewater environment as far as possible with new rubbish.

Small investment of the present invention, apply in the small towns that is fit to the economically less developed region, need not any auxiliary fuel, and operating cost is low, and all right banking 3~5 days reduces the rubbish transportation range, cuts down expenses.

In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
