Description
Technical field
The utility model relates to a kind of hot-blast stove, and particularly a kind of vertical hot-blast stove belongs to the hot-blast stove field that adds hot-air.
Background technology
Hot-blast stove has purposes widely, since be air--the flue gas heat exchange, the tradition coefficient is very little, hot-blast stove volume in the past is very big, heat pipe (in medium is housed) vertically is arranged in the hot-blast stove, and hot blast is complex flow in equipment, and the hot blast flow resistance is very big, this has just brought two aspect shortcomings: one, heat transfer coefficient is little, and metal consumption needs with the very expensive heat resisting steel of price with regard to many and burner hearth hot side; Two, the hot blast flow resistance is big, and the power of motor of hot-blast stove adapted blower fan is just big, and power consumption is just many.This two aspects shortcoming makes user's equipment investment and operating cost all big, and is unfavorable to increasing economic efficiency.
Traditional hot-blast stove, structure comprises uptake, impact tube, shell, flue, deflection plate, a plurality of fins, following air port, base, fire grate, fire grate support plate, air door, air door lid), fire door, stove face plate is taken over, baffle plate, sealing plate is provided with a plurality of heat pipes of vertical arrangement in the flue.Shell, flue, base have been formed airtight chuck space, and the deflection plate of a kind of U type (flue is a square) or semicircle (flue for circular) one on the other, the first from left right side is arranged on chuck space certain position, makes chuck form hot blast three backhauls.Impact tube is arranged on the center of cover top portion and flue top cover, passes top cover separately respectively, is communicated with space and shell 3 outside atmosphere spaces in the flue; The impact tube bottom is welded on the flue top cover.Uptake, down the air port one on the other, the first from left right side is arranged on the shell, is communicated with chuck space and housing exterior airspace.Stove face plate is arranged on the fire door outer end, and fire door is arranged on the shell on fire grate top, is communicated with burner hearth and housing exterior airspace.Air door changes and is arranged on wind (ash) and holds outdoors, and wind (ash) door is arranged on the shell of fire grate bottom, connects flue foot space and housing exterior airspace.Sealing plate is a left and right sides two halves, and the centre is semicircle orifice and impact tube clamping separately, the gap of leaking out between sealing impact tube and the last shell.Can be connected with staking or screw between sealing plate and the shell.
At above-mentioned shortcoming, improved in recent years hot-blast stove has used various forms of heat pipes to carry out heat exchange, does like this to be actually technological improvement and to enter into mistaken ideas.The cost of heat pipe own is compared with the general steel pipe of equal length and diameter and is exceeded ten several times, say heat-transfer effect merely, both and it makes no odds, the Heat Transfer of Heat Pipe on Heat Pipe thermal resistance is also bigger than general steel pipe theoretically, heat exchange area will increase on the contrary, thereby the cost of heat pipe hot-blast stove is not to reduce but greatly improve, and owing in the heat pipe medium is housed, medium heats for a long time, and heat pipe often has the danger of blast.
The utility model content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, a kind of hot-blast stove is provided, the burner hearth heat-transfer surface adopts common heat pipe, as common steel tube, common iron pipe etc., removed from the very expensive heat resisting steel of price, other convection heating surface is equally also only used common iron, and hot blast is cut apart hot flue gas formation " bellows chamber fire " layer by layer, it is very little that the hot-blast stove volume just can design, and greatly reduced the cost of hot-blast stove; In addition, adopt common heat pipe to be horizontally disposed with, the hot blast flow resistance is also little, but adapted low-power machine blower fan.This hot-blast stove thermal efficiency is higher relatively, reduces fuel consumption, has solved the big and big drawback of operating cost of equipment investment.
For this reason, the utility model provides a kind of hot-blast stove, comprises uptake 1, impact tube 2, shell 3, flue 4, deflection plate 6, a plurality of fins 7, following air port 8, base 9, fire grate 10, fire grate support plate 11, air door 12, air door lid 13, fire door 14, stove face plate 15, take over 22, baffle plate 23, sealing plate 24, wherein, in flue 4, be arranged at intervals with the heat exchanger tube 5 of 1 or 1 above horizontal positioned, and heat exchanger tube 5 is communicated with the chuck space, the left and right sides that is made of flue 4 and shell 3.
The utility model adopts horizontally disposed heat exchanger tube, heated air three backhauls are cut apart the red-hot flue gas in flue space layer by layer through this horizontally disposed heat-transfer surface, form by " bellows chamber fire ", heat exchange is abundant, and exhaust gas temperature is low, thermal efficiency height, energy savings greatly, " bellows chamber fire " heat exchange is abundant, and the little steel of having saved greatly of stove volume are made and operating cost reduces greatly.The flue of this structure burner hearth part can expensive heat-resisting steel or stainless steel, and flue do not subtract service life, greatly reduces manufacturing cost.The design of chuck space and heat exchanger tube quantity is proper, and the heated air resistance is little, can adapted low-power machine blower fan, and power consumption significantly reduces, and operating cost reduces.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
