Description

The hot blast multi-function boiler

The utility model relates to a kind of vertical hot furnace.

Stove kind, the type of existing hot hot-blast stove and carbonated drink drinking water boiler are a lot, and manufacturer is also a lot, but can only be engaged in the production of a certain thermal source type of furnace, can not make heat, warm, wind, vapour, water, five kinds of thermals source of tea produce simultaneously for various users and select for use simultaneously.

The purpose of this utility model be to provide a kind of can be on same vertical hot furnace, output is used hot blast, steam, hot water, four kinds of thermals source of boiling water simultaneously simultaneously; Output and use the hot blast multi-function boiler of any single source according to actual needs again.

The utility model complete machine structure is the tower full steel structure of multilayer series connection, body of heater by stack shell, hang courage, spiral-plate heat exchanger, top arrangement and five parts of backfire stove and constitute stack shell inner Join flue, lower link stone or metal plate for standing a stove on as a precaution against fire, last connection end socket is installed fire grate at the joint of flue and stone or metal plate for standing a stove on as a precaution against fire.Body of heater and each big combination accessory spare air blast, air-introduced machine, empty vapour purify blower fan, smoke exhaust fan and connect and all adopt garden, angle steel side framework flange, tube sheet counterpart flange, seal and install asbestos additional and close with the Bolt Connection handle.Body of heater and various supporting subordinate accessory, big or small ball valve, safety valve, stop valve, heat water valve, Pressure gauge, water gage and fitting pipe all adopt inside and outside, bright, hidden pipe screw thread be connected cock and place filler to screw bolt steady.The import and export passage of each section steam, hot blast, pyrotechnics and flue gas, the coupling components of each space layer and transition zone and UNICOM's pipeline all adopt welding method or adopt rigid connection to close with the bolt handle.Its body of heater is made up of stack shell, end socket, flue, moving grate,, two, inferior ventilation duct and firing door, ash door, filler pipe, boiling water mouth, mudhole, scale cleaning door, safety valve, water level valve, the valve of exerting oneself.It hangs courage and is made up of hot blast chamber, carbonated drink chamber, geomantic omen communicating pipe and glass water gauge, big or small ball valve etc.Its spiral-plate heat exchanger mainly is made up of shrouding, end plate, central dividing plate and plurality of sections arc.Also to add weldering and support spacing column by certain rule.Its top arrangement (furnace crown) is made up of furnace roof body, chimney, end socket, cigarette cap, blast cap, chamber, smoke barrier labyrinth, superconducting element, cross over pipe, UNICOM's axle, feed pipe, feedwater cross over pipe.Its backfire stove is by first combustion chamber (burner hearth), crater, and expansion chamber, dual firing chamber, space for collecting ashes in a stove, fire combustion export, are jealous of body, grey chamber, lower fire grating, upper fire-grating, firing door, slag notch to form.

Design of the present utility model has one-machine-multi-function, improves work efficiency, energy efficient, advantage such as applied widely.

Accompanying drawings embodiment:

Fig. 1 is a hot blast multi-function boiler agent structure schematic diagram;

Fig. 2 is hot blast multifunctional pot furnace structure installation position and connects the backfire stove location drawing;

Learn from Fig. 1-2, this utility model stack shell 1 inner Join flue 2, lower link stone or metal plate for standing a stove on as a precaution against fire 3, on connect end socket 4, at the flue 2 and the joint of stone or metal plate for standing a stove on as a precaution against fire 3 fire grate 5 is installed, on stove, be equipped with and reconcile fire grate handle 6.Bunker coal adds from firing door 8, and ashes emit from ashpit 7, and sewage is discharged from sewage door 10, and cold water adds from adding water valve 11.This utility model is when operation, and bunker coal is at first given oxygen and aiding combustion at 12, the air vents in first combustion chamber, makes coal in burner hearth 14 internal combustion.After-flame partly generates carbon dioxide, and is aerial through chimney discharging with the pyrotechnics form, and uncombusted partly generates carbon monoxide and enters second combustion chamber 15 and burnt away by twice aeration 16 oxygen supply and generate carbon dioxide and emit heat simultaneously.In order to ensure the safety of stove, Pressure gauge 17, pressure valve 18 and water glass 19, deashing 20 are installed in the edge of the end socket 4 of body of heater stack shell 1 in when operation; Off normal is put correspondence and is hung the exit of courage 9 horizontal water tubes 21 boiling water mouth 22 is installed slightly at the middle part of body of heater.The bottom of hanging courage 9 is carbonated drink chamber 23, and top is hot blast chamber 24, and for improving the temperature of carbonated drink and hot blast, carbonated drink chamber 23 is near first combustion chamber 12, and hot blast chamber 24 is near second combustion chamber 15, and hot blast is used for the drying processing of grain and food through big ball valve 25 outputs.Carbonated drink is discharged through boiling water mouth 22 and vapor outlet port 18.Replenish cold water directly feedwater from top arrangement.The middle connecting tube 26 of top hot blast of hanging courage 9 directly connects mutually with the spiral-plate heat exchanger hot-blast outlet, and the suitable for reading and furnace crown of two two and half carbonated drink cross over pipes 27 is connected.Spiral-plate heat exchanger is made two halves with central dividing plate 28 with the stamen portion space branch of heat exchanger, half be hot-air channel 29 second half be exhaust gases passes 30, two kinds of different passages serve as to obturage with shrouding 32 in the two ends of boundary central dividing plate with arc 31 all, the two ends of arc end plate 33 end sockets, distance between plates guarantees with spacing column 34.Cold air is to enter from lower floor's blast cap 35, and earlier contact heat pipe 36 absorbs behind a part of heat again that the edge from heat exchanger progressively washes away, heats the absorption heat energy that conducts heat to inside, is converted to hot blast; Flue gas is to fold to the outside internally to have formed the complete reverse-flow heat exchange of two kinds of different mediums thus.Its top arrangement (furnace crown part), for energy savings, cold air need give heat, waste heat need reclaim, the former finishes heat transfer by heat pipe 36, finish cold water under the effect of latter Ze Tong cigarette plate washer 37,35 two governor motions of blast cap and heated waste heat and be converted into hot water, realized waste heat recovery and energy savings thus.Its backfire stove for overheavy firing, enlarges the generation ability of hot blast, and the backfire stove just when being used for drying, particularly uses when being used for dried grain in enormous quantities or crop, generally is used for the hot blast heating backfire stove can be installed.This stove build vertical body of heater forward position and and body of heater connect the new combustion chamber 38 of formation, 40 3 heat transfer spaces of expansion chamber 39 and accumulation chamber.Thermal-flame at first enters expansion chamber 39 by the combustion chamber 38 of backfire stove, and lime-ash is separated and sedimentation rapidly, and pyrotechnics enters energy storage and makes 40 heat energy be hung courage 9 and absorb.Flue gas relies on the smoke exhaust fan discharging aerial, and hot blast relies on main induced draft fan and draws, and realizes complete reverse-flow heat exchange therefrom fully.The utility model adopts gravity-flow ventilation such as ature of coal is too poor or need coking in the ordinary course of things, can carry out force ventilation.When adopting gravity-flow ventilation, need make dark about 30 centimeters dark ashcans 41, in order to gravity-flow ventilation.
