Description
Technical field
The utility model relates to a kind of energy-saving environmental protection device, relates in particular to a kind of boiler flue residual heat using device.
Background technology
Along with the development of modern industry boiler and the chimney for heating, stand in great numbers and be not at one's side in us.The chimney that boiler connects, to volume of smoke and the heat of airborne release, owing to effectively not administered, reclaiming, has had a strong impact on our productive life and atmospheric environment.The smoke content that how to utilize the contained amount of heat of flue gas and reduce discharge is the object that those skilled in the art study always.
The Chinese utility model patent patent No. 201120573114.7 discloses a kind of four return water curtain smokeless environment-protection boilers, and it comprises upright shell, flue and burner hearth, characterized by further comprising: be arranged on the ring-type air compartment on described inboard wall of burner hearth; Be located at front smoke box and the rear smoke box of forward and backward of described housing; Wherein, rear smoke box communicates with described burner hearth, and front smoke box communicates with boiler smoke outlet; Three groups of smoke box and front smoke box, front smoke box and rear upper smoke box, rear upper smoke box and boiler smoke outlet annular heat transfer smoke pipes after being communicated with; Input port communicates with boiler smoke outlet by smoke exhaust pipe, the screen collector that delivery outlet communicates with air-introduced machine and dust discharge chimney by crooked dust flue.This kind of relative complex structure of boiler, manufacturing cost is high, because it directly improves the danger coefficient that has increased boiler operatiopn on boiler.
Summary of the invention
The utility model provides a kind of boiler flue residual heat using device of using safety, low cost of manufacture, waste heat recovery, reduction soot emissions.
A boiler flue residual heat using device, comprises boiler and baking oven with chimney, and described chimney is provided with the first switch, is provided with the first smoke pipe between the first switch and boiler; In described baking oven, be provided with heat radiation flue system, heat radiation flue system connects the first smoke pipe by smoke-intake pipe.This kind of boiler flue residual heat using device, by the flow direction of flue gas in the first switch control break chimney, introduced baking oven by flue gas, and by the heat radiation flue system heated oven in baking oven, the heat energy demand of greatly having saved baking oven, has reduced energy consumption.
Between described smoke-intake pipe and the first smoke pipe, by square connecting box, be connected, connecting box is provided with the first ash disposal mouth, prevents that flue dust from piling up and affecting the circulate of flue gas, has increased safety in utilization.
As the structure flue system that preferably dispels the heat, comprise plurally by the U-shaped flue that surrounds along baking oven inwall of heat radiation smoke pipe, plural U-shaped flue two ends connect smoke-intake pipe and a pipe by minute cigarette interface respectively.This kind of U-shaped flue structure realized the technology exploitativeness of heating in the baking oven for main equipments such as sock molding devices, and the utilization rate that has improved flue gas heat is set by Multilayer U-shaped flue.
A described minute cigarette interface is provided with the second ash disposal mouth, prevents dust stratification.Further structure is set to two turnings of U-shaped flue all by dividing a cigarette connecting interface to connect.
Described pipe outer end is connected at the heating smoke pipe of water tank bottom by smoke separating pipe, further utilized the water in the heat heating water tank of flue gas, reduces the energy consumption of boiler.
The air outlet that preferably heats smoke pipe as structure is connected with blower fan, and the air outlet of blower fan connects L shaped water film dedusting case by pipeline, and water film dedusting case is provided with outlet flue, to reduce the smoke content in flue gas.
The utility model boiler flue residual heat using device, by the flow direction of flue gas in the first switch control break chimney, is introduced baking oven by flue gas, and by the heat radiation flue system heated oven in baking oven, the heat energy demand of greatly having saved baking oven, has reduced energy consumption.
