Description

The split type back boiler of outer circulation
Technical field:
The utility model relates to a kind of split type back boiler of outer circulation that acts as a fuel with honeycomb briquette.
Background technology:
Honeycomb briquette is still extensively applied in city and the life in the countryside as main a kind of life fuel because relatively the combustion gas cost is low, in order to improve coal-fired heat utilization efficiency, and the domestic energy-saving water heater that designs so the waste heat that gives out at burning occurred specially.Present this class domestic energy-saving water heater that generally uses and on the Chinese patent communique, announce in the family, it generally is the burner hearth burning honeycomb briquette that surrounds at the combustion chamber made from refractory material, outer periphery at combustion chamber is equipped with a ring-shaped water jacket that thickness is very big, cold water inlet and hot water outlet pipe are set on ring-shaped water jacket, periphery at ring-shaped water jacket is provided with heat-insulation layer, the waste heat that the honeycomb briquette of burner hearth distributes when burning sees through combustion chamber and conducts to being arranged on peripheral ring-shaped water jacket, the water that leaves ring-shaped water jacket in is heated, water circulates in ring-shaped water jacket, and hot water is light and on the upper strata of ring-shaped water jacket than cold water.Cold water inlet is arranged on the bottom of ring-shaped water jacket, directly links to each other with running water pipe with pressure, utilizes the hot water outlet pipe of pressure through being arranged on ring-shaped water jacket top of running water that hot water is extruded directly use.Such domestic energy-saving water heater since ring-shaped water jacket and the cold water inlet that is attached thereto, hot water outlet pipe directly link to each other with water pipe with running water pipe, formation be the system of a sealing.Ring-shaped water jacket should bear the pressure of running water, also will bear the pressure of steam of the water generates of heating, has influenced the service life of water heater, also has problem safe in utilization simultaneously; Moreover because ring-shaped water jacket directly absorbs the heat that distributes, and hot water always remains on the higher temperature, and the thermal loss that makes hot water outwards distribute is bigger, heat utilization efficiency reduces; In use, the water of whole water jacket just no longer is fit to use in case the hot water of water jacket is reduced to certain temperature, and the utilization rate of hot water descends.
Summary of the invention
The purpose of this utility model is to provide a kind of use safer, longer service life, and the split type back boiler of the outer circulation that heat utilization efficiency and rate of thermal water utilization are higher, and existing relatively domestic energy-saving water heater can reduce manufacturing cost.
In order to achieve the above object, the split type back boiler of outer circulation of the present utility model includes combustion chamber of being made by refractory material and the burner hearth that is surrounded by combustion chamber, the less ring-shaped water jacket of thickness is set in the combustion chamber periphery, lower end at combustion chamber is provided with grate, grate connects ash bucket, go out ash bucket and be provided with the door of banking up a fire, the ring-shaped water jacket periphery is provided with heat-insulation layer, upper and lower at ring-shaped water jacket is provided with circulating water pipe, circulating water pipe connects external cyclic water tank, connect cold water inlet and hot water inlet pipe on the circulating water pipe therein, the periphery of cyclic water tank also is provided with heat-insulation layer, is provided with overflow pipe and escape pipe on cyclic water tank.
In order to improve heat utilization efficiency, the thickness that is arranged on the ring-shaped water jacket of combustion chamber periphery is 4-5cm.
In order further to improve service life, when ring-shaped water jacket uses price comparatively the expensive stainless steel material is made, the grate that is arranged on the combustion chamber lower end is inserted in the combustion chamber, be provided with cradling piece around the grate lateral surface and support combustion chamber and ring-shaped water jacket, grate with go out ash bucket and be connected to become integral body, grate and go out ash bucket and can adopt general steel plate to make then is to reach the purpose that reduces manufacturing cost.
After having adopted such structure, because the utility model has reduced to be arranged on the thickness of the ring-shaped water jacket of combustion chamber periphery, connect ring-shaped water jacket and external cyclic water tank with circulating water pipe, on cyclic water tank, set out tracheae, the hot water amount of leaving ring-shaped water jacket in is less, outwards the hot water amount of heat radiation reduces, heat utilization efficiency can effectively improve, the hot water that uses mainly leaves in the cyclic water tank, the temperature difference of hot water and external environment is reduced, the lost of heat reduces, and heat utilization efficiency also can be improved; Simultaneously the hot water temperature of ring-shaped water jacket is reduced to uniform temperature when no longer being fit to use, and the hot water that leaves ring-shaped water jacket in is also less, and the hot water that leaves cyclic water tank in can all use, and has improved the utilization rate of hot water; On cyclic water tank, be provided with escape pipe and overflow pipe, whole system becomes Open architecture, and the steam that hot water produces in the ring-shaped water jacket can be discharged, and ring-shaped water jacket no longer bears the pressure of running water and steam generation, can increase the service life effectively, guarantee safe in utilization.
