Abstract
The utility model relates to an oil fuel air heating furnace. A preheating chamber A is arranged above a heat exchanging chamber B; an axial-flow fan is arranged above a bracket of the fan arranged between the preheating chamber A and the heat exchanging chamber B and causes the heat exchanging chamber B to be communicated with the heat exchanging chamber B. A burner is arranged at the left middle part of the furnace with is arranged at a lower interior of the heat exchanging chamber B. A heat exchanger is arranged above the furnace and a heat entrance at a right side of the heat exchanger is connected with an upper right heat exit of the furnace. A preheater is arranged at a middle interior of the reheating chamber, a lower left heat entrance of the reheating chamber is connected with an upper left heat exit of the heat exchanger by a sealed heat converter joint provided with a roll diameter. A flue is arranged at an upper right fuel gas exit of the preheater. Wing panels are welded at an outer edge of the furnace, a preheating pipe of the heat exchanger and the outer wall of a heat exchanging pipe in spiral way. Air inlets above a left side of the preheating chamber A and above the preheating chamber A are provided with an air door control disc and an air door. A heating air exit below the heat exchanging chamber B. The novel structure prolongs heat exchanging procedure, lowers temperature of discharged fuel gas, improves thermal efficiency and causes soot in the flue to be easily cleaned.
Description
Technical field
The utility model relates to oven dry and uses blast heater, especially warm air oil furnace, is specially adapted to the Chinese medicine oven dry.
Background technology
At present, the interchangeable heat wind furnace adopts the cylinder monolithic construction more both at home and abroad, and heat exchange process is short, the exhaust gas temperature height, heat exchange area is little, and volume is big, and the thermal efficiency is low, because the restriction of structure can't be cleared up its air flue soot dust, thereby the thermal efficiency is reduced gradually with the passing of hot-blast stove service time.Because the hot-blast outlet in oven dry railway carriage or compartment is connected with pipeline with the air inlet of hot-blast stove, the route of waste heat recovery is long, and heat loss is big, suddenly waits to improve.
Summary of the invention
Unreasonable in order to overcome existing interchangeable heat wind furnace structural design, heat exchange process is short, the exhaust gas temperature height, heat exchange area is little, and volume is big, the thermal efficiency is low, a kind of hot-air pre-heating chamber is provided for the deficiency that air flue soot dust can't be cleared up, the utility model and Heat Room is vertical splits, and area of dissipation is big, flue dust is cleared up warm air oil furnace easily, to compensate its defect.
The technical scheme that its technical problem that solves the utility model adopts is: preheating chamber A is installed in Heat Room B top, and axial flow blower is placed in the fan supporter top between preheating chamber A, Heat Room B two Room and preheating chamber A, Heat Room B two Room are communicated.Burner is installed in the middle part, a left side of boiler, and boiler erection is in the interior bottom of Heat Room B, and heat exchanger is installed in the boiler top, and the hot air intake on its right links to each other with the top-right heat outlet of boiler.Preheater is installed in the interior middle part of preheating chamber A, and the hot air intake of its lower left has the heat exchanger joint that rolls the footpath sealing to link to each other with the upper left heat outlet of heat exchanger by design.Flue is installed in the top-right smoke outlet of preheater.Periphery and preheater, the economizer bank of heat exchanger, heat exchanger tube outer wall at boiler are welded with fin with spiral form.Air inlet directly over reaching above the left side of preheating chamber A is equipped with air door control panel and air door.Under Heat Room B, have hot-blast outlet.This new-type structure prolongs heat exchange process, has reduced exhaust gas temperature, and helical wing plate has strengthened heat exchange area, has improved the thermal efficiency, makes air flue soot dust be easy to cleaning again, and design has the heat exchanger joint that rolls the footpath sealing to guarantee that smoke evacuation do not leak.Control panel and air door can be controlled the intake of outside air.
The beneficial effects of the utility model are novel structures, and heat exchange process is long, and exhaust gas temperature is low, and heat exchange area is big, and energy consumption is low, and air flue soot dust is easy to cleaning, and smoke evacuation is not revealed, and the outside air air inflow can be regulated.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structure diagram.
The specific embodiment
In Fig. 1, preheating chamber A is installed in Heat Room B top, axial flow blower 8 is installed in fan supporter 9 tops between preheating chamber A, Heat Room B two Room and preheating chamber A, Heat Room B two Room is communicated, burner 1 is installed in the middle part, a left side of boiler 11, boiler 11 is installed in the interior bottom of Heat Room B, heat exchanger 2 is installed in boiler 11 tops, and the hot air intake on its right links to each other with boiler 11 top-right heat outlets.Preheater 4 is installed in the interior middle part of preheating chamber A, and the hot air intake of its lower left has the heat exchanger joint 3 that rolls the footpath sealing to link to each other with heat exchanger 2 upper left heat outlets by design.Flue 7 is installed in preheater 4 top-right smoke outlets.Periphery and preheater 4, the economizer bank of heat exchanger 2, heat exchanger tube outer wall at boiler 11 are welded with fin 10 with spiral form.Air inlet directly over reaching above the left side of preheating chamber A is equipped with air door control panel 5 and air door 6.Under Heat Room B, have hot-blast outlet 12.
When burner 1 is lighted the mixture of G﹠O when burning in boiler, the hot gas that burning produces enters the right-hand of heat exchanger 2 and closes operation in each heat exchange from boiler 11 and enters its upper left side again, enter the left of preheater 4 by heat exchanger joint 3, enter through economizer bank that it is right-hand, make each pipeline be full of hot gas, the flue gas that will produce in will burning is then discharged from flue 7.Extraneous cold air enters preheating chamber A from air inlet, and the big I of its intake realizes by air door control panel 5 dampers 6.Enter at first contact preheater 4 of the interior cold air of preheating chamber A, carry out heat exchange by the economizer bank outer wall and make the cold air preheating, realize once heating, air after the preheating continues to move downward, under the effect of axial flow blower 8, move downward rapidly, accelerated conduction of heat.The air of preheating enters Heat Room B by axial flow blower 8, continues to carry out heat exchange, post bake with the heat exchanger tube outer wall and boiler 2 peripheries of heat exchanger 2.At this moment, reached the hot blast temperature of baking needed through the air of twice heating.The hot-blast outlet 12 of hot gas by Heat Room enters the oven dry railway carriage or compartment and removes to dry material.Fin 10 has strengthened heat exchange area, improves heat transfer efficiency.Make more thorough that heat exchange carries out.The course of work of the present utility model that Here it is.
