Described intermediate arches cross section is triangular in shape, and intermediate arches is the most parallel with incinerator burning zone.
The length of described intermediate arches is more than furnace width.
The width dimensions of described intermediate arches looks over the 1/4-1 into incinerator burning zone from incinerator side wall.
A kind of incinerator arranging removable intermediate arches structure of the present invention uses removable intermediate arches design, intermediate arches forms effective covering to fire grate burning zone, block most of burning zone flame radiant heat transfer to the first flue, improve burning zone ignition temperature so that burn more stable；Meanwhile, intermediate arches plays the effect of flue gas water conservancy diversion, and burning zone thermal-flame flows to dryer section and after-flame section respectively, strengthens drying effect, improves rubbish burn-off rate, and then reduces First air excess air coefficient, it is achieved low NOxBurning.
The present invention arranges removable intermediate arches structure, by being inserted and removed from intermediate arches, change the size of intermediate arches, thus regulate the distribution of incineration firing radiations heat energy, wide accommodation to refuse thermal value, strengthen the incinerator adaptability to different calorific value rubbish, enable rubbish annual high-efficiency cleaning burning, adapt to the trend that refuse thermal value improves year by year simultaneously.
The concrete advantage of a kind of incinerator arranging removable intermediate arches structure of the present invention is as follows:
1, intermediate arches can effectively stop burning zone flame to the radiation of the first flue, maintains flame stabilization, can make flue gas flow direction dryer section and after-flame section simultaneously, is effectively improved drying effect and rubbish burn-off rate, reduces excess air factor, reduces NOxDischarge.
2, may be inserted into and remove intermediate arches, change cooling air quantity in intermediate arches, change intermediate arches size, be adapted to the demand of Various Seasonal refuse thermal value high-efficiency cleaning burning.
3, rubbish specific for somewhere, by changing intermediate arches size, enables incinerator to run on optimal pollutant catabolic gene point.

Reference:
1 is incinerator dryer section, and 2 is incinerator burning zone, and 3 is incinerator after-flame section, and 4 is incinerator rear arch, and 5 is slide rail, and 6 is incinerator intermediate arches, and 7 is fixture, and 8 is hydraulic cylinder, and 9 is incinerator face arch.
Detailed description of the invention
With embodiment, the present invention is elaborated below in conjunction with the accompanying drawings.
Referring to Fig. 1 and Fig. 2, the present invention provides a kind of incinerator arranging removable intermediate arches structure, this incinerator mainly by incinerator dryer section 1, burning zone 2, after-flame section 3, be positioned at the incineration furnace grate of burner hearth, incinerator face arch 9, rear arch 4, slide rail 5, fixture 7, hydraulic cylinder 8 and incinerator intermediate arches 6 and form.
Incinerator intermediate arches 6 be arranged in burner hearth between face arch 9 and rear arch 4.Arranging slide rail 5 below incinerator intermediate arches 6, the bottom surface of intermediate arches 6 is movably disposed on slide rail 5, and slide rail 5 is arranged on outside burner hearth side wall, and intermediate arches 6 is in incinerator side wall moves into burner hearth.Intermediate arches 6 is positioned at above incinerator burning zone 2, and intermediate arches 6 forms exhaust gases passes after front exhaust gases passes, intermediate arches 6 and rear arch 4 are formed in burner hearth with face arch 9.
Hydraulic cylinder 8 drives intermediate arches 6 by fixture 7, intermediate arches 6 under the driving of hydraulic cylinder 8 controls from incinerator side wall into and out burner hearth.
The bottom surface of intermediate arches 6 can arrange the pulley matched with slide rail 5, it is also possible to arranges the chute matched with slide rail 5.
Intermediate arches 6 is poured by refractory material and makes, intermediate arches 6 centrally disposed cooling duct.Intermediate arches 6 cross section is triangular in shape, and intermediate arches 6 is the most parallel with incinerator burning zone 2.The length of intermediate arches 6 is more than furnace width.The width dimensions of intermediate arches 6 looks over the 1/4-1 into incinerator burning zone 2 from incinerator side wall.
In summer, refuse thermal value is higher, can select to remove intermediate arches, or use small size intermediate arches, open the cooling wind in intermediate arches.In the winter time, refuse thermal value is relatively low, can select large scale intermediate arches, reduces intermediate arches cooling wind, blocks the burning zone flame heat loss through radiation to the first flue significantly, stablize flame temperature.Intermediate arches plays guide functions simultaneously, and high-temperature flue gas flows to dryer section and after-flame section, strengthens drying effect and burn-off rate, thus reduces First air excess coefficient and NOxDischarge capacity.
A kind of incinerator arranging removable intermediate arches structure of the present invention can be in the following ways in actual installation uses:
As depicted in figs. 1 and 2, incinerator intermediate arches 6 arranges between burner hearth face arch 9 and rear arch 4, can be moved in burner hearth by incinerator side wall.Intermediate arches 6 is positioned at above incinerator burning zone 2, and between face arch 9 and rear arch 6, intermediate arches 6 and face arch 9 form front exhaust gases passes, exhaust gases passes after being formed with rear arch 6, being controlled by hydraulic cylinder 8, intermediate arches 6 may be inserted into and remove incinerator burner hearth, it is also possible to changes intermediate arches 6 size.
Outer being poured by refractory material of intermediate arches forms, centrally disposed cooling duct.The length furnace width to be longer than of intermediate arches 6.Looking over from incinerator side wall, intermediate arches 6 width is the 1/4-1 of incinerator burning zone 2.
In sum, the incinerator arranging removable intermediate arches structure of the present invention uses the design of removable intermediate arches, by being movable into and out intermediate arches, change cooling air quantity in intermediate arches, thus regulate the distribution of incineration firing radiations heat energy, improve burning zone ignition temperature, strengthen drying effect, improve rubbish burn-off rate.
