Abstract
A mechanical grate of a large-sized incinerator comprises a drying section, a burning section and a burnout section, each section is in a moving-row smooth push structure, moving grate rows and fixed grate rows of each section are transversely staggered along a burning line, and a reasonable gap is reserved between each two adjacent grate rows. Each section is provided with an independent hydraulic drive device. Vertical drop of each two sections is about 1.2-1.4m, and each section inclines by 15 degrees. Combustion air can be delivered above the grate to burn refuse from a vent hole at the front of each section, and can also be delivered above the grate through the gap between each two adjacent grate rows. Refuse in a hopper is fed to the drying section of the grate through a pusher, and is then conveyed to the downstream of the burning line under reciprocating of the moving grate rows, and slag generated in combustion is discharged by a deslagger. The mechanical grate can be used for quickly implementing decontamination, reduction and reclamation of the refuse.
Description
Technical field
The present invention relates to the consumer waste incineration treatment facility, especially the separate unit disposal ability is 750 tons/day a big machinery fire grate.
Background technology
Along with The development in society and economy, adopting to burn has become one of main means of domestic rubbish disposal, can fast speed realize garbage harmless, minimizing and resource.Incinerator separate unit disposal ability is generally 200 ~ 600 tons/day at present, and domestic separate unit disposal ability is 700 tons/day to the maximum.
Confirm to reach under the technical feasibility situation at the total treatment scale of rubbish, consider that from the investment angle separate unit incinerator scale is big more, full factory adopts burning line quantity few more, and incineration plant number of devices and equipment investment volume are also just few more.Therefore, adopt fairly large incinerator can effectively reduce specific investment cost cost and one-time investment; Consider that from maintenance and operational management angle under the certain situation of burning disposal scale, it is few more to burn line quantity, then keep in repair, operate, manage more convenient that required operations staff is fewer.Because equipment is less relatively, full factory fault rate also decreases; Consider that from energy-conservation angle separate unit incinerator scale is big more, burning line quantity is few more, and the raw materials consumption of unit garbage disposal, energy consumption, operating cost are low more.Therefore, development trend that garbage disposal scale maximizes and the stoker fired grate that is fit to Chinese rubbish characteristic is inevitable.
Summary of the invention
The present invention reaches 750 tons of/day incinerator stoker fired grates, to realize the purpose of extensive burning disposal low heat value house refuse through improving the separate unit disposal ability of incinerator.
Concrete technical scheme of the present invention is:
A kind of large-scale incinerator stoker fired grate, stoker fired grate are dryer section, burning zone, burning segment three stage structure; Every section fire grate is and is listed as moving, forwards formula structure, and travelling oven is arranged and stationary furnace is arranged along the horizontal interlaced arrangement of burning line, is provided with rational gap between each adjacent fire grate row; Every section fire grate all is provided with independent fluid pressure drive device; Normal throw is 1.2 ~ 1.4m between every section fire grate, and the angle of inclination is 15 °; The combustion air decapacitation is delivered to the fire grate top through the air vent of fire grate segment front end and is supplied outside the waste incineration, can also deliver to the fire grate top through the gap between each adjacent fire grate row.
Further, the dryer section of the stoker fired grate of above-mentioned three stage structure, burning zone, burning segment, length is respectively 3 ~ 4m, 5 ~ 6m, 5 ~ 6m; Each section fire grate width is 8 ~ 9m, and specified mechanical load is 240 ~ 250kg/ (m
2H).
Description of drawings
Fig. 1 is a longitudinal component cross-sectional schematic of the present invention.
Fig. 2 is a lateral part of the present invention cross-sectional schematic.
Among the figure: 1-pusher, the dry fire grate of 2-, 3-combustion grate, 4-burn-out grate.
The specific embodiment
Like Fig. 1, shown in Figure 2, stoker fired grate apparatus structure sketch map of the present invention.
Embodiment of the present invention is:
Stoker fired grate as illustrated in fig. 1 and 2, a kind of 750 tons/day is made up of for 4 three sections dry fire grate 2, combustion grate 3, burn-out grate, and the angle of inclination is 15 °, and length is respectively 3.61,5.61,5.61m, and length overall is 14.83m altogether; Each section fire grate width is 8.58m, and the gross area is 127.24m2, and specified mechanical load is 245kg/ (m2h).The nearly 1.3m of normal throw between every section fire grate, rubbish is able to fragmentation and upset when falling.Every section fire grate all is designed to row dynamic formula structure, and travelling oven is arranged and the horizontal interlaced arrangement of line is burned on stationary furnace arrangement edge, is provided with rational gap between each adjacent fire grate row, through the reciprocating motion that travelling oven is arranged rubbish is sent to burning line downstream.The combustion air decapacitation is delivered to the fire grate top through the air vent of fire grate segment front end and is supplied outside the waste incineration; Can also deliver to the fire grate top through the gap between each adjacent fire grate row; Relative motion between travelling oven arrangement and stationary furnace are arranged can prevent the generation that combustion air stops up fully, and reasonably air distribution mode is fit to the burning of waste of low heating value.Every section fire grate all is provided with independent fluid pressure drive device, and by ACC control automatically respectively, every section fire grate is by 6 Driven by Hydraulic Cylinder based on combustion case for the speed of service.
During use, rubbish is put in the garbage feeding bucket through garbage grab bucket crane or other transport with identity function; Rubbish in the hopper is delivered on the pusher through the rubbish elephant trunk that is arranged on the bottom, and pusher repeats to move back and forth, and is continuous, smooth and easy and stably to the fire grate feed, is sent to slag dropping tube while the rubbish that pusher is sent here burns on fire grate.Pusher 1 pusher ability is 31.25 tons/hour.The speed of service of pusher can be regulated based on the requirement of treating capacity and evaporation capacity.Fire grate moves back and forth speed and is regulated separately by ACC, with control waste incineration bed thickness.Combustion air after the steam air heater preheating is sent into the fire grate top by the slag bucket side and is burnt away the refuse.Rubbish is dry on dry fire grate, in burning on the combustion grate, on burn-out grate, burn fully.Slag after burning is discharged by mucking machine through slag dropping tube; The leakage slag that drying, burning, burning segment fire grate leak down in the slag bucket passes through to leak the slag conveyor delivery to mucking machine.
During use, utilize measuring instrument monitoring rubbish such as temperature in the stove, pressure to burn situation, like 850 ℃ of flue gases whether sustainable 2 seconds, fire box temperature, pressure etc.; Through economizer exit sampling flue gas, measure NO in the flue gas
XConcentration, CO concentration and O
2Whether indexs such as concentration, it is up to standard to understand the burning effect.
Consumer waste incineration treatment facility of the present invention, separate unit disposal ability are the big machinery fire grate of 750t/d.Through pusher the rubbish in the hopper is delivered to the fire grate dryer section; The reciprocating motion of arranging through travelling oven then is sent to rubbish and is burned the line downstream; Burn the slag that produces and discharged by mucking machine, this system can fast speed realize garbage harmless, minimizing and resource.
