Abstract
The invention discloses a vertical three-pass hot-water boiler. The vertical three-pass hot-water boiler comprises boiler skin, a combustor, a combustion chamber, a boiler cylinder, heat exchange pipe sets, smoke chambers and a smoke outlet, wherein the combustion chamber is located at the bottom of the boiler cylinder, the combustor is located outside the boiler skin and is communicated with the combustion chamber, heat exchange pipes are vertically arranged in the boiler cylinder above the combustion chamber, the smoke chambers include the first turning smoke chamber and the second turning smoke chamber, the first turning smoke chamber is located on the left side of the top of the boiler cylinder, the second turning smoke chamber is located at the upper right corner of the combustion chamber, the heat exchange pipe sets include the first-pass heat exchange pipe set, the second-pass heat exchange pipe set and the third-pass heat exchange pipe set in sequence from left to right, the smoke outlet is located over the third-pass heat exchange pipe set, the second turning smoke chamber is separated from the combustion chamber through a water clamping groove, and the second turning smoke chamber is externally connected with a drainage pipe. According to the vertical three-pass hot-water boiler, the condensation process of smoke is prolonged in a limited space, the discharging temperature of the smoke is lowered, heat in the smoke can be recovered easily, and absorption of sulfide and nitride in the smoke is facilitated.
Description
Technical field
The invention belongs to hot-water boiler field, be specifically related to a kind of vertical three pass hot water boilers.
Background technology
Be illustrated in figure 1 the design of conventional hot water boiler, primarily of boiler exoperidium 1, combustor 2, combustion chamber 3, boiler barrel 4, exhaust opening 5, smoke-box 6, a few part composition of set of heat exchange tubes.Flue gas enters set of heat exchange tubes by combustion chamber 3, arrives exhaust opening 5 enter in air again through smoke-box 6, and its flue gas circulation direction is as shown in the direction of arrow in Fig. 1.Because the stroke of flue gas in set of heat exchange tubes is short, it is also shorter to be detained cool time, causes smog discharge temperature higher, and carries a large amount of heats in flue gas and be not fully utilized, cause the waste of resource; On the other hand, the nitride that burning generates and sulfide are the major pollutants of air, and the temperature of conventional boiler fume emission is higher, is unfavorable for the absorption of nitride and sulfide, and these mass emissions cause air pollution in air.
Summary of the invention
The present invention aims to provide a kind of vertical three pass hot water boilers.By optimizing the layout of set of heat exchange tubes and smoke-box, prolong smoke condensation backhaul route, reducing smog discharge temperature, with the heat better entrained by recovered flue gas, and promoting the abundant absorption of nitride and sulfide in flue gas, protection of the environment.
For this reason, the technical solution adopted in the present invention is: a kind of vertical three pass hot water boilers, comprise boiler exoperidium, combustor, combustion chamber, boiler barrel, set of heat exchange tubes, smoke-box and exhaust opening, described combustion chamber is positioned at bottom boiler barrel, described combustor be positioned at boiler exoperidium outer and and combustion chamber, described set of heat exchange tubes is vertically arranged in the boiler barrel above combustion chamber, it is characterized in that: described smoke-box comprises the first turning smoke-box and the second turning smoke-box, first turning smoke-box is positioned at boiler barrel top left side, second turning smoke-box is positioned at the upper right corner of combustion chamber, described set of heat exchange tubes is from left to right divided into a backhaul set of heat exchange tubes successively, two return set of heat exchange tubes, three backhaul set of heat exchange tubes, described exhaust opening is positioned at directly over three backhaul set of heat exchange tubes, a described backhaul set of heat exchange tubes is communicated with combustion chamber and the first turning smoke-box, described two return set of heat exchange tubes is communicated with the first turning smoke-box and the second turning smoke-box, described three backhaul set of heat exchange tubes are communicated with the second turning smoke-box and exhaust opening, described second turning smoke-box and combustion chamber are separated by water clip slot, described second turning smoke-box is connected to drainpipe, for the condensed water of the second turning smoke-box is caused outside boiler exoperidium.
Further, described water clip slot is " L " shape, and the two ends of water clip slot are communicated with boiler barrel respectively.
The present invention sets up the first turning smoke-box and the second turning smoke-box on the basis of conventional boiler, set of heat exchange tubes is from left to right divided into successively a backhaul set of heat exchange tubes, two return set of heat exchange tubes, three backhaul set of heat exchange tubes, and to run in water pipe at the second turning smoke-box.Its beneficial effect is: the three backhaul circulations completing flue gas in limited space; make use of space dexterously; and structure is simple, low cost of manufacture; prolong smoke condensation backhaul route; significantly reduce the exhaust temperature of flue gas; heat better in recovered flue gas, and the absorption promoting combustion product nitride and sulfide, with the protection of the effective utilization and environment that realize resource.
