The specific embodiment
embodiment is referring to shown in Fig. 1-4, the vertical heating furnace that this heating porcelain ball is used, comprise the body of heater 5 with heat-insulation layer 18, body of heater 5 has the vertical body of heater (be body of heater be arranged vertically) of exhanst gas outlet 1 for the top, the bottom of body of heater 5 is provided with supporting leg 12 and ash bucket 13, and the bottom deslagging mouth of ash bucket 13 is provided with high temperature flapper 14, be provided with air inlet 11 on the body of heater 5 above ash bucket 13, on the body of heater 5 above air inlet 11, burner 10 is housed, the inside of the body of heater 5 above burner 10 is provided with the oblique grate 7 in bottom that body of heater inner (burner hearth) is divided into lower floor's flue gas generation chamber 16 and upper strata heat exchange chamber 17 use, have porcelain ball outlet 6 on the body of heater 5 at the least significant end place of the oblique grate 7 in bottom, and porcelain ball outlet 6 is provided with outlet insertion plate door 4, be provided with the oblique grate 15 in top of a plurality of interlaced arrangement in upper strata heat exchange chamber 17 above the oblique grate 7 in bottom, have porcelain ball entrance 3 on the body of heater 5 at the most significant end place of the oblique grate 15 in top, and porcelain ball entrance 3 is provided with entrance insertion plate door 2.Also be provided with circulating flue gas entrance 8 on body of heater 5 between the oblique grate 7 in described burner 10 and bottom.
The oblique grate 15 of the oblique grate 7 in described bottom and top all is certain inclination angle with horizontal line, and the Grill space of the oblique grate 7 in bottom and the oblique grate 15 in top is stuck in the grate seam to prevent the porcelain ball less than the diameter of porcelain ball.
Referring to Fig. 3, Fig. 4, in the present embodiment, the madial wall of body of heater 5 is provided with brace table 19, the oblique grate 15 of the oblique grate 7 in described bottom and top is all taken and is placed on brace table 19, that is to say, bottom oblique grate 7 and the oblique grate 15 in top are supported by the brace table that is fixed on body of heater inner both sides, like this benefit of design be bottom oblique grate 7 and the oblique grate 15 in top just take and be placed in body of heater 5, replacing for convenience detach.
In the present embodiment, the oblique grate 7 in bottom and the oblique grate 15 in top are added up and are had three layers (arranged by an oblique grate 7 in bottom and two oblique grates 15 in top and form), being staggered arranges, also can be the "the" shape arranged, make the porcelain ball that enters from the import of porcelain ball be able to sufficient heat exchange through grate the time.Simultaneously, have three groups to be the brace table at certain inclination angle with horizontal line in body of heater, the oblique grate 15 of the oblique grate 7 in bottom and top is arranged on brace table, has filled the porcelain ball on each layer grate.Oblique grate 15 "the" shapes in the oblique grate 7 in bottom and top are arranged the porcelain ball is steadily rolled in the above, guaranteed the porcelain ball continuously, equably the heat absorption, simultaneously the porcelain ball is with respect to the rolling of grate also cooling grate uniformly and effectively, prevents the grate excess Temperature and affects the metallic character of material.
Described air inlet 11, burner 10 and circulating flue gas entrance 8 have formed the flue gas generation systems, but the burner single fire also can doublely burn gas, two kinds of fuel of liquefied petroleum gas.Described porcelain ball entrance 3, porcelain ball outlet 6, the oblique grate 15 of the oblique grate 7 in bottom and top have formed porcelain ball heat-exchange system.
The ash bucket 13 that described hearth combustor below arranges is used for depositing the ashes (ashes that fuel combustion produces is hoarded in ash bucket 13) that changes and produce due to fuel.The bottom deslagging mouth of ash bucket bottom is provided with high temperature flapper 14, high temperature flapper 14 can be by discharging the judgement of the temperature ashes that temperature is lower, stop simultaneously the leakage of high-temperature flue gas, so both guaranteed safety, improve again the heat exchange efficiency of burner hearth, can prevent from leaking due to high-temperature flue gas the shortcoming of the reduction of heat exchange efficiency that causes.
In working order, the porcelain ball of low temperature enters body of heater inside by lifting means from porcelain ball entrance, then the porcelain ball successively is rolled on the oblique grate 15 in top of low layer from the oblique grate 15 in the top of high level, be rolled at last on the oblique grate 7 in bottom, then under the drive of the burying scraper in porcelain ball exit, exported outside stove by burying scraper.When rolling, the porcelain ball absorbs flue gas heat on grate.Porcelain ball after discharge drops on burying scraper 9, and burying scraper 9 can be as required with quantitative, continuous the exporting from vertical heating furnace of the porcelain ball of high temperature.
That is to say, at the burying scraper below porcelain ball outlet 6 at a slow speed under drag interaction, the porcelain ball of each layer rolls and discharges from porcelain ball outlet 6 to low side from grate is high-end, porcelain ball entrance 3 constantly replenishes new porcelain ball and enters body of heater, the porcelain ball is the motion that descends step by step in the process of rolling, form countercurrent flow with the flue gas that successively rises, farthest improved heat exchange efficiency, meanwhile also to allow grate obtain cooling comparatively equably for the progressive rolling movement of porcelain ball, very significantly extended the service life of grate.
Meanwhile, fuel burns in burner, the high-temperature flue gas that burner produces is lower furnace portion by the flue gas generation chamber 16(of lower floor) be upper furnace to heat exchanging chamber chamber, upper strata 17() flow, see through simultaneously the oblique grate 15 of the oblique grate 7 in bottom and top, the porcelain ball 20 on grate is heated, the heat transfer process of flue gas and porcelain ball is countercurrent flow, and the heating process of porcelain ball is dynamic heat.Weary gas after heating is discharged by the exhanst gas outlet 1 at body of heater top, weary gas after discharge (also being low-temperature flue gas) enters lower floor's flue gas generation chamber 16 through flue again by circulating flue gas entrance 8, then mixes backward upper strata heat exchange chamber 17 tops with new high-temperature flue gas that burner produces mobile, the porcelain ball is heated.
That is to say, the weary gas of discharging enters in body of heater as circulating flue gas (can be used for to heating cigarette temperature lower the temperature adjusting) by the circulating flue gas entrance again, this part weary gas mixes the temperature that reaches suitable after entering body of heater with high-temperature flue gas, and then rises and to pass grate and to carry out heat exchange with porcelain ball on grate.
