Abstract

The utility model relates to a vertical two-purpose hot-blast stove which provides clean air and hot water for the livestock and poultry house, the greenhouse, etc. The utility model is additionally provided with a circular upper cover plate of a furnace body, a circular ring plate which can seal the gap of a furnace wall and a furnace core, fume exhaust pipes which are communicated with the upper cover plate of the furnace body and the circular ring plate and is uniformly distributed around the circumference, fume exhaust pipes which are uniformly distributed on a bedplate of the furnace core and a water tank positioned at the top of the furnace body. The utility model effectively increases the air overflow area, improves the heat transfer efficiency and has the advantages of energy saving and multifunction.

Description

Vertical two-purpose hot-blast stove

The utility model relates to a kind ofly both can provide clean hot air for heating space (as livestock and poultry house, greenhouse etc.), and the vertical two-purpose hot-blast stove of hot water can be provided again.

At present at northern area, the heat supply in winter of livestock and poultry house, temperature house generally adopts boiler, radiator central heating mode, also have adopt warming stove, wall with flues, methods such as flue.All these modes all can only reach the purpose of heating, and for its feeding house that needs ventilation, environment was muddy in airtight warming meeting in winter caused giving up can't bear, and causes multiple disease, so that have a strong impact on economic benefit.For solving this a pair of contradiction of heating and ventilating, the present utility model people has designed a kind of in 8 or seven years be fuel, the plate-type heat-exchange hot-blast stove of using the axial flow blower heat air delivery with the coal, in this hot-blast stove, heated air is in the annulus of bonnet and tweer after the preheating, six roots of sensation trunnion through the furnace roof position is and axially enters the combustion chamber high-temperature region, sends from the discharge pipe of body of heater waist subsequently.This hot-blast stove has obtained applying in national number provinces and cities, has obtained good economic benefit, but finds in actual applications, because six roots of sensation trunnion area of passage (about 1700cm less than normal of furnace roof portion ²), and the combustion chamber diameter dimension has limited the expansion of throat pipe diameter, relies on the wing plate heat exchange simultaneously in the combustion chamber, causes the hot blast rate deficiency, windage is bigger, thereby has influenced heat exchange efficiency.

The purpose of this utility model is to provide that a kind of novel area of passage is big, heat exchange efficiency is high, and can utilize the vertical two-purpose hot-blast stove of the heating of hot-blast stove fume waste heat, hot-water supply.

The said vertical two-purpose hot-blast stove of the utility model, comprise bonnet 4, furnace wall 3, chimney 12, cigarette ash storehouse 13, furnace core wall 7, combustion chamber base plate 5,

discharge pipe

6,17, base 1, fire door 2, of the present utility model being characterised in that, it also comprises Circular Plate 16, vertical connection furnace upper cover plate and the Circular Plate in circular body of heater upper cover plate 15, sealing furnace wall and furnace core wall gap and the smoke exhaust pipe 9 that is circularly and evenly distributed, vertical connection furnace upper cover plate and combustion chamber base plate and equally distributed smoke exhaust pipe 10 and the water tank 11 that is positioned at the body of heater top on the combustion chamber base plate.

This novel vertical two-purpose hot-blast stove, by changing the mode that heated air enters the combustion chamber high-temperature region, increased the air area of passage effectively, reduced air drag, improved heat exchange efficiency, simultaneously, hot-blast stove top water tank can effectively utilize fume afterheat, for operating personnel provide hot water, embodied energy-conservation, multi-functional advantage.

Narrate embodiment of the present utility model below in conjunction with accompanying drawing.

Fig. 1: front view of the present utility model.

The A-A cutaway view of Fig. 2: Fig. 1.

Fig. 3: two of the utility model cisten mechanism figure.

Fig. 4: three of the utility model cisten mechanism figure.

The utility model will be formed the complete heating ventilator system of a cover with propeller fan, airduct, electric cabinet, exhaust blower in actual applications.

At Fig. 1, among Fig. 2, under the effect of axial flow blower draft, clean air is entered by the annular gap between bonnet 4 and the furnace wall 3, carry out heat exchange and preheating with the furnace wall that has wing plate 83 with uniform temperature, the air that is preheated is in upper of furnace body radially to be crossed Circular Plate 16 and enters combustion chamber, since on the Circular Plate in an end of equally distributed smoke exhaust pipe 9 and the combustion chamber end of equally distributed smoke exhaust pipe 10 and Circular Plate 16 and combustion chamber all be arranged in burner hearth, cause its temperature very high, and then make combustion chamber become the high-temperature region, be heated to higher temperature rapidly so enter the air of combustion chamber, and from

discharge pipe

6 or 17 discharges, thereby finish the task of producing hot blast.

Except burner hearth heats smoke exhaust pipe, flue gas by burner hearth process smoke exhaust pipe also has heat effect to smoke exhaust pipe, owing to have cross wing plate 18 on the even distribution of smoke exhaust pipe and every smoke exhaust pipe, guarantee that preheated air carries out sufficient heat exchange in combustion chamber, thereby improved the heat exchange efficiency of hot-blast stove.

The utility model also is provided with water tank 11 at the top of hot-blast stove, the waste heat heating water tank of the flue gas of utilize discharging during practical application makes it also simultaneously can provide hot water providing under the prerequisite of enough cleaning hot blast, it is multi-functional to reach a stove, makes full use of the purpose of the energy.

The cisten mechanism of hot-blast stove shown in Figure 1 is the cylinder bodily form, and the central authorities of cylinder water tank are run through by chimney, and the below of cylinder water tank is cylinder bodily form cigarette ash storehouse 13, and the side in cigarette ash storehouse is provided with door 14, can clear up cigarette ash thus.

The water tank of hot-blast stove shown in Figure 3 is for being the stereochemical structure that symmetrical inverted right-angled trapezium rotation constitutes by longitudinal profile, and the central authorities of water tank are run through by chimney.

The water tank of hot-blast stove shown in Figure 4 also can be for being that the parallelogram that symmetry is placed rotates the stereochemical structure that constitutes by longitudinal profile, and the central authorities of water tank are run through by chimney.
