Figure 2 shows that traditional vertical water tube boiler, formed by shell 1, flue 2, combustor 3, smoke-intake pipe 8, water pipe 4, pipe 9 etc.Flue 2 is arranged in shell 1, and longitudinally arranges with shell 1 is coaxial.Combustor 3 is positioned at outside shell 1 and communicates with flue 2 by smoke-intake pipe 8, is provided with some water pipes 4 in flue 2, and the two ends of water pipe 4 are connected in the cavity between shell 1 and flue 2, the in-built full water of cavity between shell 1 and flue 2.Flue gas after combustor 3 burnings is entered in flue 2 by smoke-intake pipe 8, the space between water pipe 4, then enter atmosphere by pipe 9.Flue gas flows between water pipe 4, and water is interior heated at water pipe 4.Between flue 2 bottoms and shell 1 bottom, be provided with fire resistant heat preserving concrete, protection boiler bottom is not heated.
The problem that above-mentioned two kinds of boilers exist is: (1) flue gas is directly by pipe exhaust atmosphere, high fume temperature, and the heat utilization efficiency of flue gas is low; (2) between flue bottom and shell bottom, be provided with fire resistant heat preserving concrete, reduced the contact area of flue and shell, correspondingly reduced the heating surface area of water between flue and shell.
Utility model content
The utility model improves for above-mentioned technical problem, intends providing the high heat-exchange performance atmospheric vertical water pipe chamber combustion that a kind of exhaust gas temperature is low, heating surface area is large hot-water boiler.
For this reason, the technical scheme that the utility model adopts is: a kind of high heat-exchange performance atmospheric vertical water pipe chamber combustion hot-water boiler, comprise shell (1), flue (2) and combustor (3), described flue (2) is positioned at shell (1), and longitudinally arrange with shell (1) is coaxial, in described flue (2), be provided with some water pipes that are parallel to each other (4), described combustor (3) is positioned at outside shell (1) and communicates with flue (2) bottom by smoke-intake pipe (8), also be provided with pipe (9) on the top of flue (2), key is: in the cavity between described flue (2) bottom and shell (1) bottom, be provided with water-cooling jacket (5), described water-cooling jacket (5) is by the steel plate that is arranged on flue (2) bottom outer wall, be arranged on the water stream channel that the steel plate of shell (1) bottom interior wall surrounds, described water pipe (4) is horizontal water tube, is positioned at the middle part of flue (2), is also integrated with condensing unit (7) in flue (2), and condensing unit (7) is positioned between water pipe (4) and pipe (9).
Be preferably, between described water pipe (4) and horizontal plane, have the angle α of 5～15 °, the layout of the baffle plate of being more convenient for.
Further, described pipe (9) is positioned at outside the sidewall on flue (2) top.The position of pipe is changed into outside the sidewall on top by flue top, make flue gas in the time that flue flows to pipe by bending, more abundant to washing away of condensing unit, heat exchange is better.
The beneficial effects of the utility model:
(1) in the cavity between flue bottom and shell bottom, water-cooling jacket is set, simple in structure, compact, increase the heating surface area of water, can reach the effect of fire resistant heat preserving concrete protective boiler bottom, but making is more simple and convenient;
(2) integrated installation condensing unit in flue, is reduced to below 110 ℃ exhaust gas temperature, and heat transfer effect is more remarkable.
