Abstract
The utility model discloses a boiler, particularly a horizontal hot blast furnace, comprising a combustion chamber, a heating chamber and a preheating chamber. The complete machine is a horizontal direct-connection all-steel all-protection sleeve structure, and the utility model adopts the pipeline flange connection. Multilayer of heat exchange spaces are communicated by communicating pipes, and multilevel of positive and negative reciprocating passages controls the deflection by baffles. The combustion chamber and the heating chamber are connected together by welding method, and the heating chamber and the preheating chamber are tightened by rigid connecting bolts. The utility model has the advantages of large heat transfer area, high thermal efficiency, energy saving, low cost, air pollution prevention, etc.
Description
The utility model relates to a kind of air-heating furnace that is used for grain feed and medicinal material oven dry.
Existing air-heating furnace all adopts the reciprocating type or vertical structure of the bitubular usually.Above structure hot-blast stove heat transfer area is little, and the thermal efficiency is low.Use this hot-blast stove must use fat coal again, cost is high and cause environmental pollution again easily.
Order of the present utility model ground is to provide a kind of heat transfer area big, and flow resistance is little, and thermal efficiency height is to hang the reciprocating type horizontal direct heat wind furnace of multilayer that courage runs through front and back.
The utility model comprises combustion chamber, heating clamber and gives three parts in hot cell.Complete machine is horizontal direct connection all steel, all risk insurance temperature tube-in-tube structure.Its complete machine adopts pipeline flange to connect, and each layer heat transfer space adopts communicating pipe to connect.The multistage contrary hot-blast stove that adopts barrier plate control baffling along reciprocal passage.Its combustion chamber is a framework with the angle steel, is outer wall with the sheet metal, is inwall with standard refractory brick, connect with heating clamber with slotted-angle shelving, in the combustion chamber, be provided with the inclined grate of casting by cast iron, form by five fire grates, keep 15mm ventilation seam between every fire grate, amount to 18 strip holes.Whole fire grate tiling is contained on the refractory brickwork, forms 20-30 degree inclination angle with horizontal plane.Also be provided with firing door, ash door, skimming door in the combustion chamber.Its heating clamber is to run through front and back with hanging courage; Constitute central transition zone; Link with communicating pipe and heating air box all around, reciprocal baffling is controlled with the barrier plate in the multilayer space.Heating clamber is back and forth arranged by multi-layer sheet, adopts communicating pipe to connect, and forms two stage burning spaces, front and back and cold and hot air transformed space and flue gas waste heat recovery space with the barrier plate.
It is big to the utlity model has heat transfer area, and thermal efficiency height is saved the energy, and cost is low and can prevent advantage such as air pollution again.
Accompanying drawings embodiment:
Fig. 1 is the horizontal hot air furnace overall schematic.
Learn from figure: this utility model is when assembling, and complete machine is horizontal direct connection all steel, all risk insurance temperature tube-in-tube structure.Its complete machine adopts pipeline flange to connect, and each layer heat transfer space adopts communicating pipe to connect.At different levels contrary along reciprocal passage employing barrier plate control baffling structure.The backfire stove of this utility model partly is made up of 2 two parts in combustion chamber 1 and ash discharging chamber.Backfire furnace body 3 tops connect coal-feeding door 5, the following ashpit 6 that connects, and skimming door 7 is installed in the middle part of the right flank of body of heater 3.In the bottom of backfire furnace body 3 and combustion chamber 1 five inclined grates 8 are housed.This utility model is a drying medium with the air when operation, and cold air mainly enters from the top lower floor cigarette cap mouth 9 of horizontal hot air furnace.Cold air chamber 10 gives hot cell 11 by way of air and heats, and then enters heating air box 12 and accept combustion chamber high temperature flame and directly heat, and heats once more.At last by hot-air channel 13, pass the high temperature center and enter and hang in the courage 14 central heat transfer zone.Hot blast is through communicating pipes 15 central dividing plate 16 and wait pipe 17 and hot blast gatherer 18 fully mixes heat absorption and heats the temperature that causes hot-air and can peak more than 200 ℃.Under the effect of No. nine air-introduced machines 19, draw at last, send in the foodstuff drying device by hot-blast pipe line 20 from hot-blast stove.Pyrotechnics enters from combustion chamber 1 in the passage of core beacon chamber 21 of horizontal hot air furnace.In order to improve the service life of stove; the head that hangs courage 14 in the high-temperature region is coated with to load onto and thickly protects for the refractory material of 20-25; flue gas passes head end brace rod 22 and enters flue gas case 23; heat is absorbed by hot blast chamber 24; enter chimney 26 from floss hole 25 at last; make flue gas do cyclonic motion, grit is separated from flue gas in the inside of deduster 27.Purified gas enters among the atmosphere.During use, give the hot cell and be from cold air sucking, about finish two space layer give heat, make cold air can be increased to 60-70 ℃ from normal temperature.During use, drive air-introduced machine earlier, after drive the flue gas blower fan, when stopping using, close the flue gas blower fan earlier, air blower is closed in the back.
