Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of Vertical Steel Plate hot-blast stove of novel high-efficiency and energy-saving, and as shown in Figure 1, body of heater adopts whole steel sheet to make, and forms inside and outside two-layer structure, comprises inner layer steel plate 1 and outer layer plate 2.
Specifically, the inner layer steel plate 1 of body of heater adopts heatproof to be not less than the heat-resisting steel sheet and plate of 800 DEG C, can select the heat-resisting steel sheet and plate of heatproof 800-1200 DEG C, and in practical application, excellent employing heatproof reaches the heat-resisting steel sheet and plate of 1800 DEG C is good.Inner layer steel plate 1 is evenly laid with a plurality of airing hole 10 (see Fig. 2).Its material of outer layer plate 2 of body of heater is carbon steel material, can adopt ordinary carbon steel material (such as Q235 carbon steel).Have gap between outer layer plate 2 and inner layer steel plate 1 and be configured with ventilation passageway 3, the upper end in this ventilation passageway 3 is closed, and the circular air inlet mouth of bottom connects the annular all gas storehouses 5 connected, and ventilation passageway 3 is configured to the air-cooled interlayer of isobaric air compartment.The inlet end in annular all gas storehouses 5 is provided with the frequency conversion fan 6 for providing wind regime.
Can put burner 7 by the efficient end of furnace bottom when this novel vertical steel plate hot wind furnace uses and provide thermal source, the end, puts the heat radiation of burner 7 combustion fuel generation and is delivered on internal layer heat-resisting steel sheet and plate (inner layer steel plate 1).By frequency conversion fan 6 to annular all gas storehouse 5 air blast, annular all gas storehouse 5 balancedly rouses normal temperature air in ventilation passageway 3.Normal temperature air forms equipressure in ventilation passageway 3; and by the airing hole 10 on internal layer heat-resisting steel sheet and plate to air blast in burner hearth; form a two-sided cooling layer; one air cooling wall is formed especially in the inner wall surface of internal layer heat-resisting steel sheet and plate; guarantee that the surface temperature of internal layer heat-resisting steel sheet and plate is not higher than 500 DEG C, protection internal layer heat-resisting steel sheet and plate.A large amount of normal temperature airs rouses by frequency conversion fan 6 passageway 3 of entering to ventilate, while cooling internal layer heat-resisting steel sheet and plate, burning radiation and the heat being passed to internal layer heat-resisting steel sheet and plate are melted down in thorax with the form transmission of hot blast, be mixed in the high-temperature flue gas of fuel combustion generation, may be adjusted to the heat smoke that temperature is 200 DEG C-700 DEG C, for industry provides heat energy, reduce thermal loss.Preferably, the lateral wall of outer layer plate 2 also can be sticked heat-insulation layer 4, for reducing radiation loss further.
Here it is important to note that due to fireproof high-temperature resistant requirement, traditional hot-blast stove all can only adopt fire-resistant pouring material manufacture, and steel are due to the limitation of fire resistance, perhaps can expect but really cannot apply realization in prior art.This is novel is apply dexterously and in conjunction with isobaric wind principle and two-sided cooling technology, designed by flexible structure, innovatively designs steel plate hot wind furnace structure, to become in hot-blast stove field a great innovation.
Further, consider that steel plate is heated and understand expansion status, according to stove size in design, preferably inner layer steel plate 1 is divided at least two sections from bottom to up, namely be divided at least two independently cylinders, each drum diameter is successively decreased from top to bottom, and each cylinder can stretch in free wxpansion.As in the specific embodiment that provides in Fig. 1, inner layer steel plate 1 is divided into three sections, is the first inner layer steel plate 11, second inner layer steel plate 12 and the 3rd inner layer steel plate 13 under upper.Adopt described independent segmented formula design; whole internal layer heat-resisting steel sheet and plate inner sleeve expanded by heating can be reduced first and the Superposed Deformation amount formed; second described in, at least two sections adjacent two are intersegmentally configured with interlayer gap (as being configured with interlayer gap 14 between the first inner layer steel plate 11 and the second inner layer steel plate 12 in Fig. 3); cold air passes through at a high speed from this interlayer gap; brattice is formed at the inwall of internal layer heat-resisting steel sheet and plate; greatly strengthen the effect of two-sided cooling, protect internal layer heat-resisting steel sheet and plate further.Preferably, the corresponding end of adjacent two sections of described inner layer steel plate 1 upwards mutually flushes in level or is staggeredly set (as shown in Figure 3), and this structural design is more conducive to interlayer gap and plays effect.
The utility model Vertical Steel Plate hot-blast stove adopts forced-air blast mode, can the effective regulation and control blow rate required by frequency conversion fan 6, can the temperature of outlet hot blast of accurate adjustment hot-blast stove by the adjustment blow rate required, conveniently can adjust the load of hot-blast stove.Separately, this novel vertical steel plate hot wind furnace is in installation process, the agent structures such as inner layer steel plate sleeve (inner layer steel plate 1), carbon steel shell (outer layer plate 2) can by prefabrication, erecting bed directly lifts splicing and can complete, and substantially reduces engineering time and the construction cost of hot-blast stove.
The foregoing is only preferred embodiment of the present utility model, all equalizations done with the utility model right change and modify, and all should belong to the scope of the utility model claim.
