Abstract
A sealing smoke box structure of a gas boiler comprises a smoke box barrel body, an outer sealing door is arranged on one side of the smoke box barrel body, an inner sealing door is arranged between the inner side of the smoke box barrel body and the outer sealing door, heat preservation layers are arranged on the outer sealing door, the inner sealing door and the upper side and the lower side of the inner sealing door, heat insulation aluminum foil is arranged between the heat preservation layers, and a fire-resistant cement heat insulation layer is fixedly arranged on the inner side of the inner sealing door. According to the sealing smoke box structure of the gas boiler, the double-layer sealing doors are adopted in a smoke box door, the thickened heat preservation layer is additionally arranged between the outer sealing door and the inner sealing door, meanwhile, the fire-resistant cement heat insulation layer is fixedly arranged on the inner side of the inner sealing door, and reinforcing sealing strips and the like are adopted between the layers. Heat leakage in the boiler is completely eradicated, radiation losses of a smoke box panel and the smoke box barrel body are effectively reduced, and the temperature of the outer surface of a smoke box is greatly reduced. The heat efficiency of the boiler is improved, and the aims of saving energy, reducing emissions and being environmentally friendly are achieved.
Description
Technical field
The utility model relates to a kind of gas boiler, is specially a kind of sealed cigarette box structure for gas fired-boiler.
Background technology
Along with economical and scientific and technical development, and the requirement of national energy-saving, environmental protection, the thermal efficiency of people to boiler and the consumption of fuel are had higher requirement, for the smoke box structure in past, because heat-insulation layer is thin, effect of heat insulation is poor, encapsulation process is improper, cause smoke box panel, smoke-box shell temperature higher, thereby make the radiation loss of boiler many, the thermal efficiency reduces.
Summary of the invention
The problem existing for above-mentioned prior art, has invented a kind of gas fired-boiler sealed cigarette box structure, and the boiler heat radiation that has solved prior art is many, the problem that the thermal efficiency is low.
A kind of gas fired-boiler sealed cigarette box structure, comprise smoke box cylindrical shell, be provided with external seal door in smoke box cylindrical shell one side, it is characterized in that correspondingly with external seal door in smoke box cylindrical shell inner side being provided with interior hermatic door, between hermatic door and interior hermatic door and the upper and lower both sides of interior hermatic door are equipped with heat-insulation layer outside, described heat-insulation layer is made up of the stack of layered insulation material, between heat-insulation layer, be provided with heat insulation aluminium foil, in smoke box, be provided with double-layer clapboard, between dividing plate, seal heat insulationly with asbestos cord, be fixed with refractory cement thermal insulation layer in interior hermatic door inner side.
Described a kind of gas fired-boiler sealed cigarette box structure, is characterized in that described heat insulation aluminium foil break joint gap is sealed by aluminum foil and adhesive tape.
Described a kind of gas fired-boiler sealed cigarette box structure, is characterized in that being provided with sealed ceramic cordage between smoke box cylindrical shell and smoke box panel and external seal door and smoke box panel.
Gas fired-boiler sealed cigarette box structure of the present utility model, by smoke box door being adopted to double-layer seal door, and set up thickened heat insulation layer between two, fixed refractory cement thermal insulation layer in interior hermatic door inner side simultaneously, all adopt enhanced leaktightness bar etc. at each interlayer, stop the heat leakage in boiler, effectively reduced the radiation loss of smoke box panel and smoke box cylindrical shell, greatly reduced the temperature of smoke box outer surface.Improve boiler thermal output.Energy-saving and emission-reduction are reached, the object of environment-friendly and green.
Brief description of the drawings
Fig. 1 is smoke box sealed structural representation.
In figure, 1-smoke box panel, 2-combustor is taken over, 3-external seal door, 4-smoke box dividing plate, hermatic door in 5-smoke box, 6-refractory cement thermal insulation layer, 7-heat-insulation layer, 8-smoke box cylindrical shell.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Shown in Fig. 1, a kind of gas fired-boiler sealed cigarette box structure of the present utility model, comprise smoke box cylindrical shell 8, be provided with external seal door 3 in smoke box cylindrical shell one side, hermatic door bottom is provided with combustor and takes over 2 outside, smoke box cylindrical shell inner side and the parallel interior hermatic door 5 of smoke box that is provided with of external seal door, between external seal door and interior hermatic door, be provided with thickened heat insulation layer 7 simultaneously, this heat-insulation layer 7 adopts the stack of layered insulation material to form, and between every layer of heat-insulation layer, add heat insulation aluminium foil, shut with aluminum foil and adhesive tape in gap between aluminium foil again, be provided with double-layer clapboard 4 in the upper and lower both sides of interior hermatic door, between dividing plate, seal heat insulation with asbestos cord, and in dividing plate 4 and smoke box, between hermatic door 5, horsestone cotton cord seals, between smoke box cylindrical shell 8 and smoke box panel 1, clamping ceramic fibre rope seals, between external seal door 3 and smoke box panel 1, the same ceramic fibre rope that clamps seals.The upper and lower both sides of interior hermatic door are also made with thickened heat insulation layer 7, have heat insulation aluminium foil between each heat-insulation layer.Interior hermatic door inwall is also fixed with refractory cement thermal insulation layer 6.
By each possible heat radiation point is carried out to specification sealing, stop scattering and disappearing of the interior quality of stove completely.Hermatic door temperature approaches room temperature.
