Abstract
The utility model provides a double-channel smoke reverse high-effect hot air furnace. The utility model is composed of an outer furnace housing, an inner furnace housing, a chimney, a pipe coil radiator and a coal combustion furnace, wherein the pipe coil radiator is fixed in the inner furnace housing, and the inner furnace housing is fixed in the outer furnace housing; a smoke inlet of the pipe coil radiator is connected with the coal combustion furnace through a smoke exhaust pipe, and the smoke outlet of the pipe coil radiator is connected with the chimney. Compared with the prior art, the double-channel smoke reverse high-effect hot air furnace has the characteristics of reasonable design, simple structure, easy manufacture, energy saving, high thermal efficiency, and convenient use and installation, etc. Thus, the utility model has good popularization and use values.
Description
The utility model relates to a kind of drying plant or air heating apparatus, the two coiled pipe heat radiator type binary channels flue gas reverse heat-exchange high-efficient hot air furnaces of specifically a kind of twin furnace shell.
The furnace binding of the air-heating furnace of prior art is to have single furnace shell list coiled pipe radiator to constitute, enter in the coiled pipe radiator that the single casting iron pipe makes from the high hot flue gas of coal burning stove, the coiled pipe radiator is installed in the hotair chamber in single furnace shell, directly contact and carry out heat exchange with cold air, thereby existing deficiency is that the heat loss area of dissipation big, the coiled pipe radiator of furnace shell is little, the thermal efficiency is low in actual production, not only energy consumption is big and also heating after air themperature do not reach designing requirement.
The purpose of this utility model provides a kind of twin furnace shell, the two reverse high-efficient hot air furnaces of coiled pipe heat radiator type binary channels flue gas of two coiled pipe.
The purpose of this utility model realizes in the following manner, adopt the twin furnace shell structure, be designed to the cold air preheating channel between outer furnace shell and the interior furnace shell, two cast-iron radiators of dual layer arrangement carried out heat exchange about furnace shell neutralized in air after the preheating entered again, in order to improve heat exchanger effectiveness, outside at cast iron pipe has added fin, thereby makes the air themperature of air-heating furnace after heating under the fuel that consumes as much than improving more than 50% originally.
Accompanying drawing is the plan structure schematic diagram of the reverse high-efficient hot air furnace of binary channels flue gas.
Below with reference to Figure of description Double-channel smoke counter-direction high-effect hot air furnace of the present utility model being done Explain.
Double-channel smoke counter-direction high-effect hot air furnace of the present utility model, its structure be by outer furnace shell 5, Interior furnace shell 6, chimney 8, coiled pipe radiator 3 and coal burning stove 9 consist of, and coiled pipe radiator 3 is fixing In interior furnace shell 6, interior furnace shell 6 is fixed among the outer furnace shell 5, coiled pipe radiator 3 advance mouth by row Smoke pipe 10 and coal burning stove 9 join, and the outlet flue of coiled pipe radiator 3 and chimney 8 join.
Space between outer furnace shell 5 and the interior furnace shell 6 is an air preheat passage 13, and inlet of cold air 11 is located at the left end of outer furnace shell 5, and the centre of interior furnace shell 6 is a hot-air channel 14, and the right-hand member of interior furnace shell 6 has preheated air import 12, and left end is a high temperature air outlet 1.
Be fixed with fin 4 on the outer wall of coiled pipe radiator 3, the side of interior furnace shell 6 is provided with ash discharging hole 7 and air temperature modification door 2.
Embodiment:
Its processing and fabricating of the reverse high-efficient hot air furnace of binary channels flue gas of the present utility model is very simple and convenient, shown in the by specification accompanying drawing the double-deck furnace shell of air-heating furnace is designed, the coiled pipe radiator is by dual tube designs, finned on the outer wall of coiled pipe radiator, during installation, flange-cooled coiled pipe radiator is by among the furnace shell in bilayer is fixed on up and down, the mouth that advances of two coiled pipe radiators is attempted by on the flue tube that joins with the coal burning stove simultaneously, the outlet flue and the chimney of two coiled pipe radiators connect together, the left end of furnace shell is outside opened in the import of cold air, air intlet after the preheating is opened the right-hand member at interior furnace shell, high temperature air is discharged from the hot-air outlet of interior furnace shell left end, the effect of air temperature modification door be when the temperature of high hot-air is too high, open the air temperature modification door allow a part of cold air directly enter by adjustment doors in the furnace shell to reduce the temperature of high hot-air.This air heater or hot-blast stove are mainly used in the heat drying of material, as the heat drying of the heat drying of dehydrated vegetables, melon and fruit, brewery's brewers malt and as dry heat equipment in other industrial production.
Double-channel smoke counter-direction high-effect hot air furnace of the present utility model is compared with existing technology, and has and establishes Count reasonable, simple in structure, be easy to processing, save the energy, thermal efficiency height, easy to install and use etc. Characteristics, thereby, have good value for applications.
