Abstract
The utility model relates to a hot blast stove with residual heat recovery and uniform heat exchange. An inner heat transferring sheet connected with the wall of a smoke collecting chamber is arranged in the smoke collecting chamber, and a conical outer cover is arranged outside the wall of the smoke collecting chamber. An air intake passage is formed between the conical outer cover and the wall of the smoke collecting chamber, and an outer heat transferring sheet is connected between the smoke collecting chamber and the conical outer cover outside the smoke collecting chamber. The outer side of the lower end of a chimney is provided with a rain preventing plate. The four sides of the upper end of a heat exchanging chamber are respectively provided with long rectangular air inlets, and the two opposite angles of the lower end of the heat exchanging chamber are provided with two adjacent long rectangular air outlets which are connected with semicircular air outlet pipes. The utility model has the advantages that the residual heat of the smoke collecting chamber is recovered and reused, the heat exchange of the heat changing chamber is uniform, the heat exchanging efficiency is high, etc.
Description
The utility model relates to the stove and accessory technical field, belongs to the improvement of hot-blast stove structure.
Hot-blast stove is through combustion fuel air heat to be become high-temperature flue gas, high-temperature flue gas flows in smoke pipe, gas to be heated flows outside smoke pipe, high-temperature flue gas is with heat transferred gas to be heated in the flow process, flue gas discharges out of the furnace through smoke collecting chamber and chimney then, and take away part of waste heat, whole body of heater also conducts heat to the external world by the furnace wall.After existing like product, high-temperature flue gas are flowed out by heat exchange chamber, do not have waste heat recovery during by smoke collecting chamber, cause the waste heat waste; Gas to be heated is to enter heat exchange chamber by one or several air admission hole, flow out outside the stove by one or several venthole again, when gas to be heated is flowed through heat exchange chamber, flow distribution is extremely inhomogeneous, the dead angle is many, causes to contact unevenly with fume pipe, and the heat of partial fume pipe (or pipe a certain section) can not pass to gas to be heated effectively, and discharge chimney with flue gas, cause thermal loss.
The purpose of this utility model provides a kind of waste heat that reclaims smoke collecting chamber, make in the heat exchange chamber heat exchange even, to improve the hot-blast stove of heat exchange efficiency.
The utility model be achieved in that in smoke collecting chamber, be provided with the smoke collecting chamber wall joining in heat transfer sheet, outside the smoke collecting chamber wall, be provided with the awl outer cover, form air intake passage between this awl outer cover and the smoke collecting chamber wall, heat transfer sheet outside between smoke collecting chamber and the awl outer cover outside it, being connected with, be provided with weather shield in the outside, chimney lower end, be respectively equipped with the elongated rectangular shape air inlet on four limits, heat exchange chamber upper end.Owing to inside and outside smoke collecting chamber, be provided with heat transfer sheet, given heat behind the heat of cold air absorption heat transfer sheet to be heated, enter again in the heat exchange chamber of hot-blast stove, make the waste heat in the smoke collecting chamber obtain utilizing.For making the heat exchange chamber heat exchange even, be provided with the elongated rectangular shape air inlet on four limits, heat exchange chamber upper end, be provided with two adjacent elongated rectangular shape gas outlets in diagonal angle, heat exchange chamber lower end one side, and join with the semicircular escape pipe; Also can be respectively equipped with two adjacent elongated rectangular shape gas outlets according to instructions for use, and join with corresponding two semicircular escape pipes in both sides, diagonal angle, heat exchange lower end.Owing to adopt rectangle four limit air inlets and rectangle gas outlet, thereby strengthened air inlet and gas outlet area, when gas inlet and outlet area and smoke pipe length are identical, can obviously increase effective heat exchange length of smoke pipe, to improve heat exchange efficiency.The shape of the utility model heat exchanger outer cover is made octahedron, is convenient to produce, make.
Compared with the prior art the utility model has smoke collecting chamber heat recovery, even, the heat exchange efficiency advantages of higher of heat exchange chamber heat exchange.
Below in conjunction with accompanying drawing the utility model is done to describe:
Fig. 1 is the utility model sectional elevation
Fig. 2 (A-A) the utility model smoke collecting chamber horizontal sectional drawing
Fig. 3 (B-B) the utility model gas to be heated enters heat exchange chamber air inlet position horizontal sectional drawing
Fig. 4 (C-C) the utility model heated air flows out the heat exchange chamber position horizontal sectional drawing (escape pipe) of giving vent to anger
Fig. 5 (C '-C ') the utility model heated air flows out the heat exchange chamber position horizontal sectional drawing (two escape pipes are arranged) of giving vent to anger
Referring to accompanying drawing: in smoke collecting chamber 3, be provided with smoke collecting chamber wall 14 joining in heat transfer sheet 4, outside smoke collecting chamber wall 14, be provided with awl outer cover 12, form air intake passage 13 between awl outer cover 12 and the smoke collecting chamber wall 14, heat transfer sheet 5 outside between smoke collecting chamber wall 14 and the awl outer cover 12 outside it, being connected with, be provided with weather shield 2 in the outside, chimney 1 lower end, be respectively equipped with rectangle air inlet 11 on four sides in heat exchange chamber 7 upper ends, one side is provided with two adjacent rectangle gas outlets 9 at diagonal angle, heat exchange chamber 7 lower end, and join with semicircular escape pipe 10, according to using needs also can be respectively equipped with two adjacent rectangle gas outlets 9, and join with corresponding two semicircular escape pipes 10 in both sides, diagonal angle, heat exchange chamber 7 lower end.Because heat transfer sheet 4 in being provided with in the smoke collecting chamber 3, flue gas heat in the chamber can be delivered on the outer outer heat transfer sheet 5 of smoke collecting chamber wall 14 and smoke collecting chamber wall, cold air behind air intake passage 13 by outside heat transfer sheet 5 give heat, and then enter in the heat exchange chamber 7 and carry out the elevated temperature heat exchange with smoke pipe 6, because the four sides of heat exchange chamber 7 upper ends is provided with elongated rectangular shape air inlet 11, make the air that enters in the heat exchange chamber 7 contact equably with whole smoke pipes 6 at once, there is not flow blind angle, make whole smoke pipes and gas to be heated carry out sufficient heat exchange, increased effective heat exchange length of smoke pipe.
Because heat exchange chamber 7 lower ends are provided with elongated rectangular shape gas outlet 9, make that to be heated gas flow distribution in the whole heat exchange chamber 7 more even, obviously reduce or eliminate flow blind angle, can make whole smoke pipes and be heated the gas even contact and carry out heat exchange, improve its heat exchange efficiency.
Heat exchanger outer cover 8 be shaped as octahedron, make technology simple, handsome in appearance, and increased the rigidity of outer cover 8.
