Description

A kind of energy-saving water cold wall boiler
Technical field
This utility model relates to boiler technology field, specifically a kind of energy-saving water cold wall boiler.
Background technology
Coal-burning boiler is by the water burn-out in boiler or to be converted into steaming as fuel, the heat that coal burning produces with coal Vapour, the flue gas that coal burning produces is discharged by flue.In order to improve work efficiency and save the energy, boiler is constantly entered by people Row improves, and especially adequacy and fume afterheat to fired coal combustion utilizes conveniently, but, at boiler to heating water tanks process In, will also result in scattering and disappearing of amount of heat, the heat that especially in water tank, hot water absorbs outwards is dissipated by water tank wall and boiler wall Heat, the efficiency of heating surface causing boiler is low, and conventional insulation material not only increases boiler cost, it is difficult to fundamentally solves heat and dissipates Mistake problem, it is impossible to realize the recycling of heat, it is therefore desirable to the energy-conservation use of a kind of novel boiler.
Utility model content
The purpose of this utility model is to provide a kind of energy-saving water cold wall boiler, to solve to propose in above-mentioned background technology Problem.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of energy-saving water cold wall boiler, including hot water outlet pipe, boiler pedestal, cold water inlet, boiler jacket body, pot Stove inner housing and boiler furnace, described boiler pedestal is provided with boiler jacket body, boiler inner housing and boiler furnace, Boiler Furnace Form hot-water cavity between thorax and boiler inner housing, be provided with fire grate bottom boiler furnace, be provided with slag-drip opening below fire grate, above fire grate It is provided with fire door, boiler furnace top connection chimney, between boiler inner housing and boiler jacket body, forms cold water cavity, cold water cavity upper end Connect hot-water cavity by water injection hole, bottom cold water cavity, connect cold water inlet, bottom hot-water cavity, connect hot water outlet pipe.
As further program of the utility model: described boiler furnace is arranged in boiler inner housing.
As further program of the utility model: described boiler inner housing is arranged in boiler jacket body.
As further program of the utility model: be provided with waterproof layer in described cold water cavity and hot-water cavity.
Compared with prior art, the beneficial effects of the utility model are: described a kind of energy-saving water cold wall boiler, structure sets Counting reasonable, easy for operation, fired coal combustion efficiency is high, and burning adequacy is good, conveniently heats water in hot-water cavity, fume afterheat Utilization rate is high, convenient by cold water cavity water filling, is prevented effectively from scattering and disappearing of heat in hot-water cavity, effectively realizes the recovery profit of heat With, improve the efficiency of heating surface of boiler, save fire coal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-hot water outlet pipe, 2-fire grate, 3-slag-drip opening, 4-fire door, 5-boiler pedestal, 6-cold water inlet, 7-heat Water cavity, 8-cold water cavity, 9-water injection hole, 10-chimney, 11-boiler jacket body, 12-boiler inner housing, 13-boiler furnace.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, in this utility model embodiment, a kind of energy-saving water cold wall boiler, including hot water outlet pipe 1, pot Furnace foundation seat 5, cold water inlet 6, boiler jacket body 11, boiler inner housing 12 and boiler furnace 13, described boiler pedestal 5 is arranged Having boiler jacket body 11, boiler inner housing 12 and boiler furnace 13, boiler furnace 13 is arranged in boiler inner housing 12, Boiler Furnace Form hot-water cavity 7 between thorax 13 and boiler inner housing 12, be provided with fire grate 2 bottom boiler furnace 13, below fire grate 2, be provided with slag-drip opening 3, fire grate 2 is arranged over fire door 4, boiler furnace 13 top connection chimney 10, and the coal-fired fire door 4 that passes through joins boiler furnace 13 In, the coal-fired slag produced after burning in boiler furnace 13 is discharged by slag-drip opening 3, and the heat that fired coal combustion produces is to hot water Chamber 7 is heated, and the flue gas that fired coal combustion produces is discharged by slag-drip opening 3.
Described boiler inner housing 12 is arranged in boiler jacket body 11, shape between boiler inner housing 12 and boiler jacket body 11 Becoming cold water cavity 8, cold water cavity 8 upper end is provided with waterproof layer in connecting hot-water cavity 7, cold water cavity 8 and hot-water cavity 7 by water injection hole 9, Connect cold water inlet 6 bottom cold water cavity 8, connect hot water outlet pipe 1 bottom hot-water cavity 7, by cold water inlet 6 to cold water cavity Injecting cold water, the heat absorption that hot-water cavity 7 is outwards distributed by cold water in 8, the cold water after heat absorption flows into hot-water cavity by water injection hole 9 7, then absorb the heat of fired coal combustion in boiler furnace 13 and heat up and become hot water and discharge from hot water outlet pipe 1, setting of cold water cavity 8 It is set effective and avoids scattering and disappearing of heat in hot-water cavity 7, effectively realize the recycling of heat, improve the efficiency of heating surface of boiler.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting Involved claim.
