Background technology
In the hot-blast stove kind that aquaculture is used, more vertical vertical fire tube hot-blast stove, by lower perforated plate, pyrotechnics tube bank, the upper perforated plate of combustion chamber, top, combustion chamber, go up smoke-box, chimney etc. and form, combustion chamber and heat dump be about conjoined structure.Its operation principle is: the high-temperature flue gas that is produced that in the combustion chamber, burns of the fuel on the fire grate upwards washes away upper perforated plate and gets into the pyrotechnics pipe; Arrive again afterwards and go up smoke-box; Outlet flue from last smoke-box is discharged to outdoor through chimney at last; The heat that heat that the combustion chamber inner bag is absorbed and pyrotechnics tube bank are absorbed carries out heat exchange under the heat radiation wind action that combustor outer casing place cooling fan is blown into, heated air is blown from hot-blast outlet at last, thereby realizes the purpose of heating.The shortcoming of vertical vertical fire tube hot-blast stove is:
1 because the high-temperature flue gas that produces directly washes away lower perforated plate and gets into the pyrotechnics tube bank during fuel combustion on the fire grate; This segment distance can be lacked relatively, when Coal-fired capacity increases, when combustion intensity strengthens; Insufficient almost inevitable 2 heat radiation wind that burn are blown into from the air-cooled interlayer of combustion chamber; Upwards continue as the pyrotechnics tube bank through air-cooled interlayer and dispel the heat, the heat exchange mode between heat radiation wind and the radiator structure belongs to parallel baffled, and is many compared with the radiating effect difference of transversal flow.The too high cigarette temperature of smoke-box has not only been wasted heat but also be unfavorable for carbon distribution clearly on 3, and carbon distribution drops on the problem that can occur smoldering on the following fuel bed during clear carbon distribution.The lower perforated plate of 4 vertical fire tube hot-blast stoves and following pipe end are in the state of thermal expansion stress and localized hyperthermia's double influence, and be restricted service life.5 when meeting the requirements of heating during temperature, is difficult to banking easily, like this can't brake can cause the waste and the too high phenomenon of temperature of fuel.The hot blast that 6 hot-blast stoves blow out is because of temperature height and moisture-free, and the high temperature low humidity can reduce the comfort level of breeding environment greatly.
Summary of the invention
In order to overcome the technical deficiency of traditional hot wind furnace; The present invention provides a kind of horizontal vertical fire tube hot-blast stove, and the technical problem that this hot-blast stove will solve is: increase effective endotherm area, reduce heat radiation blowing dead angle; The radiating effect of enhance heat structure further improves the thermal efficiency of hot-blast stove; Convenient clear carbon distribution is kept high-efficiency operation; Reduce localized hyperthermia and thermal expansion stress to the influence of pyrotechnics tube bank and tube sheet service life with the raising hot-blast stove; The employing hot blast is combustion-supporting, can promote combustion efficiency and under the effect of temperature controller, realize automatic banking function; Set up dependency structure, make this hot-blast stove have the steam humidification function.
The technical solution adopted for the present invention to solve the technical problems is:
Make combustion chamber and radiator relatively independent; About arrange just can possess abundant burning, clear carbon distribution makes things convenient for and some conditions of the phenomenon that can not occur smoldering; Because the buffer board of top, combustion chamber; Expansion chamber, and the last smoke-box of radiator upper perforated plate top has increased the running time and the range ability of high-temperature flue gas relatively together as the running route of high-temperature flue gas before getting into the pyrotechnics tube bank; Can realize the abundant burning of fuel, also can strengthen the endothermic effect of the heat-absorbing structure before the pyrotechnics tube heat sucker; During clear carbon distribution, carbon distribution drops on play smoke-box, because the temperature of smoke-box is low relatively down, the temperature of following smoke-box bottom is more under burning-point, so do not worry the phenomenon of can appearance burning and smoldering after carbon distribution falls.
