Abstract
The utility model relates to an ordinary pressure environment-friendly boiler which comprises a water jacket boiler body, a chimney arranged on the upper portion of the water jacket boiler body and arc-shaped short water pipes. A hollow cylindrical water jacket with the sealed lower end is arranged inside the water jacket boiler body. The lower end of the chimney extends into middle of the hollow cylindrical water jacket, and gaps between the chimney and the hollow cylindrical water jacket and between the hollow cylindrical water jacket and the water jacket boiler body form flues. The upper ends of the at least two arc-shaped short water pipes are communicated with the hollow cylindrical water jacket, and the lower ends of the arc-shaped short water pipes are communicated with the water jacket boiler body. When the ordinary pressure environment-friendly boiler is used, the boiler is heated, and high-temperature smoke penetrates the flues between the chimney and the hollow cylindrical water jacket and between the hollow cylindrical water jacket and the water jacket boiler body to be discharged. Heat in the smoke can be recovered through the flues, and coal ash discharged into the air can be reduced. The ordinary pressure environment-friendly boiler has the advantages of being large in heating area, capable of improving the heat efficiency and reducing pollution and the like.
Description
Technical field
The utility model relates to a kind of boiler, especially a kind of normal pressure environment-protection boiler.
Background technology
Boiler miscellaneous in the market, its mechanism generally is that specific flue is set, the place of flue approach arranges water tank then, thereby with the water heating, utilizes water, vapour to reach the purpose of heating.Boiler in the market is the more of fuel with the coal.The coal-burning boiler that has a large capacity and a wide range will consume a large amount of coal, also is the main coal-smoke pollution source of China simultaneously.
General vertical fire coal normal-pressure hot-water boiler, mainly formed by shell end socket, flue, flue top, seal down, impact tube and horizontal water tube, combustion chamber placement is in flue, fuel burns at fixed grate, gravity-flow ventilation, flue gas is the transversal flow horizontal water tube in flue, enters atmosphere through impact tube, chimney.The heat utilization efficiency of general boiler is relatively low, has that the smoke temperature is too high, a heating surface area deficiency of water, problem such as air pollution is big to external world.
Summary of the invention
It is big that the purpose of this utility model provides a kind of heating surface area, can improve the thermal efficiency of boiler, reduces the normal pressure environment-protection boiler that pollutes.
The utility model normal pressure environment-protection boiler; Comprise water jacket furnace, be arranged on the chimney on water jacket furnace top, the arc short piece; Described water jacket furnace inside is provided with the hollow cylinder water jacket of a following end closure; The lower end of described chimney extend into the middle part of described hollow cylinder water jacket; Between described chimney and the hollow cylinder water jacket and the space between hollow cylinder water jacket and the water jacket furnace forms flue; Described arc short piece is no less than two, and the upper end of arc short piece is communicated with the hollow cylinder water jacket, and the lower end of arc short piece is communicated with water jacket furnace.
As optimization.Can ring-shaped water jacket be arranged in described chimney arranged outside, described ring-shaped water jacket top is communicated with water jacket furnace; The upper end of described hollow cylinder water jacket is communicated with described ring-shaped water jacket.Gap between ring-shaped water jacket and the hollow cylinder water jacket forms flue.
Can also comprise, be no less than two arc long water pipes; The top of arc long water pipe is communicated with the top of water jacket furnace; The bottom of arc long water pipe is communicated with water jacket furnace is communicated with the top of position with the arc short piece near.
Can, described water jacket furnace top is provided with delivery port, the bottom is provided with water inlet.
In addition, the arc long water pipe is identical with arc short piece quantity, can be set to 6～24.
When using this normal pressure environment-protection boiler, fuel burns in the bottom; In heating boiler, high-temperature flue gas passes between chimney and the hollow cylinder water jacket and the flue between hollow cylinder water jacket and the water jacket furnace is discharged, can the heat in the flue gas be reclaimed by this flue, can reduce simultaneously the discharging of coal ash in the atmosphere.
This utility model normal pressure environment-protection boiler; It is big to have heating surface area, can improve the thermal efficiency of boiler, reduces beneficial effects such as pollution.
Description of drawings
Fig. 1 normal pressure environment-protection boiler of the present utility model structural representation.
Fig. 2 is the look up structural representation of Fig. 1 along the A-A line.
The specific embodiment
The normal pressure environment-protection boiler; As Fig. 1, shown in Figure 2, comprise water jacket furnace 1, be arranged on the chimney 2 on water jacket furnace 1 top, hollow cylinder water jacket 3, arc short piece 4, arc long water pipe 5.
Water jacket furnace 1 inside is provided with the hollow cylinder water jacket 3 of a following end closure; Chimney 2 arranged outside have ring-shaped water jacket 6; Ring-shaped water jacket 6 tops are communicated with water jacket furnace 1; The upper end of hollow cylinder water jacket 3 is communicated with ring-shaped water jacket 6.The lower end of chimney 2 extend into the middle part of hollow cylinder water jacket 3; Between ring-shaped water jacket 6 and the hollow cylinder the water jacket 3 and space between hollow cylinder water jacket 3 and the water jacket furnace 1 forms flue.
Arc short piece 4 is 12, and the upper end of arc short piece 4 is communicated with hollow cylinder water jacket 3, and the lower end of arc short piece 4 is communicated with water jacket furnace 1.
Arc long water pipe 5 is 12, and the top of arc long water pipe 5 is communicated with the top of water jacket furnace 1; The bottom of arc long water pipe 5 is communicated with water jacket furnace 1 is communicated with the top of position with arc short piece 4 near.
Water jacket furnace 1 top is provided with delivery port 7, and the bottom is provided with water inlet 8.The lower end of water jacket furnace 1 is provided with fire bars 9.
During use, the upper end of hollow cylinder water jacket can be communicated with by cross current ring-shaped water jacket or other modes; The outside of chimney can not arrange ring-shaped water jacket, and the hollow cylinder water jacket is communicated with water jacket furnace top, and the quantity of arc short piece and arc long water pipe is no less than two, can be set to 6～24.
