The inner cavity of the upper stove body is provided with a water-cooled wall tube whose outer margine is provided with fins, and the outside of the upper stove body is provided with a bent water tube which is contained by a smoke box. The inner cavity of the lower stove body is provided with a smoke partition box, a water-cooled grate and a grate from top to bottom, and the upper stove is connected with the lower stove body by a connecting tube. The utility model improves the heating area and makes the fuel obtain sufficient combustion. The discharge concentration of the smoke is less than 200 mm / cubic meter, and the lingeman blackness is 0-1. The utility model can supply not only the drinking water but also the bath water.

Description

Double-layer fire grate vertical water heater for boiling water and bath

The utility model relates to a kind of stove and accessory, especially the vertical tea-bath furnace of the double-layer grate that can supply drinking water.

A kind of drinking water boiler is arranged at present, the cigarette fontanel is being installed, water inlet pipe, be provided with inner furnace body in the body of heater inner chamber of outlet pipe and fire door, be provided with at the inner chamber of inner furnace body and hang body of heater, the top of inner furnace body by last connecting tube with hang body of heater and join, the bottom of hanging body of heater joins with inner furnace body by second line of a couplet adapter, fire grate is arranged at the bottom of body of heater, upside at fire grate is provided with secondary air channel, downside at fire grate is provided with airduct one time, place the coal on the fire grate under the secondary wind action, to burn, its flue gas is discharged from outside the body of heater through gap and the cigarette fontanel that hangs between body of heater and the inner furnace body, simultaneously the water in the body of heater is heated, it exists heating surface area little, and gas residence time is short, flue dust is big, shortcomings such as the incomplete combustion and the thermal efficiency are low.

The purpose of this utility model provides the vertical tea-bath furnace of a kind of double-layer grate, and it not only can supply with drinking hot water, and still can supply with bathing water.

The purpose of this utility model is achieved in that upper furnace body and lower furnace body form one admittedly by ring flange, outer rim has the water screen tube of fin by in the inner chamber that vertically is arranged at inner furnace body, its two ends join with inner furnace body respectively, the two ends of curved water pipe join with the outside of upper furnace body respectively, the smoke box that the cigarette fontanel is installed will be bent the outside that water pipe contains and be arranged at upper furnace body, a smoke baffle plate is set between water screen tube that has fin and inner furnace body, a smoke baffle plate is set between upper furnace body and smoke box, in the inner chamber of lower furnace body, from top to bottom be provided with every smoke box, the water-cooled grate and the fire grate of water pipe are housed, and the inner water sleeve of upper furnace body and lower furnace body joins by connecting tube.

Owing to adopt such scheme, increased heating surface area, coal is fully burnt, smoke dust discharge concentration is less than 200 milligrams/cubic metre, lingemann blackness is 0-1, thermal efficiency height, and floor space is little, coal adaptability is extensive, and it not only can supply drinking water, and bathing water can be provided.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a profile structural map of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the B-B cutaway view of Fig. 2.

Fig. 4 is the C-C cutaway view of Fig. 2.

Among the figure 1, fire grate 2, water-cooled grate 3, have the water screen tube 7 of fin, curved water pipe 8, smoke box 9, cigarette fontanel 10, fire door 11, smoke baffle plate 12, upper furnace body 13, lower furnace body 14, inner furnace body 15, flue outlet every smoke box 4, connecting tube 5, ring flange 6, outer rim

In embodiment illustrated in figures 1 and 2, upper furnace body (12) and lower furnace body (13) are fixed into one by ring flange (5), outer rim has the water screen tube (6) of fin by in the inner chamber that vertically is arranged at inner furnace body (14), its two ends join with inner furnace body (14) respectively, the two ends of curved water pipe (7) join with the outside of upper furnace body (12) respectively, the smoke box (8) that cigarette fontanel (9) are installed will be bent that water pipe (7) contains and fix with the outside of upper furnace body (12), on the exhaust gases passes that has between water screen tube of fin (6) and the inner furnace body (14), a smoke baffle plate (11) is set, on the exhaust gases passes between upper furnace body (12) and the smoke box (8), a smoke baffle plate (11) is set, on the exhaust gases passes between inner furnace body (14) and the upper furnace body (12), a flue outlet (15) is set, in the inner chamber of lower furnace body (13), from top to bottom be equipped with successively every smoke box (3), the water-cooled grate (2) and the fire grate (1) of water pipe are housed, upper furnace body (12) joins by connecting tube (4) with the water jacket of lower furnace body (13), side at lower furnace body (13) is provided with three fire doors (10), sets out water pipe at the opposite side of lower furnace body (13).The utility model adopts the anti-combustion system that burns, be the upside process preheating of coal at water-cooled grate (2), drying and burning, its flue gas is in backspace under the barrier effect of smoke box (3), enter water-cooled grate (2) and the formed combustion space of fire grate (1) by water-cooled grate (2), cause the unburnt coal that drops on the fire grate (1) to burn away, its flue gas is successively by every smoke box (3) and the formed gap of lower furnace body (13) (as shown in Figure 4, in the direction of the clock), outer rim has the water screen tube (6) and the formed exhaust gases passes of inner furnace body (14) of fin, flue outlet (15), upper furnace body (12) and formed exhaust gases passes of smoke box (8) and cigarette fontanel (9), be discharged from outside the body of heater, so that heat fully exchanges, flue dust falls within the ash dropping hopper through smoke box (8) simultaneously, to reduce air pollution.
