Description

The condensation hot water boiler of the collapsible layout of a kind of three backhaul

Technical field

The utility model belongs to thermal hardware technical field, and in particular, it relates to the condensation hot water boiler of the collapsible layout of a kind of three backhaul.

Background technology

Boiler is that one utilizes various fuel, electricity or other energy, by the heating liquid of institute's splendid attire to certain parameter, and externally exports the equipment of heat energy.

The hot-water boiler of general employing pan shell type structure, its shell, flue, stove coolant-temperature gage inside the heating surfaces such as smoke pipe is substantially identical, traditional boiler is positioned at bottom or the top of boiler body regardless of burner, the movement locus of flue gas is consistent with the track of current, flue gas temperature in flow process progressively reduces, and the temperature of medium raises gradually, more to afterbody, the temperature difference between flue-gas temperature and medium temperature can reduce, heat transfer effect is then caused to decline, cause final flue gas with a large amount of waste heats discharged to air, lose heat energy in vain, not only reduced boiler thermal output but also to environment.

In addition, traditional boiler does not have segmentation but integral arrangement, so floor space is larger due to boiler.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is the condensation hot water boiler of the openly collapsible layout of a kind of three backhaul, by the change in flue gas and medium direction, increases the temperature difference between flue gas and medium, lifting heat transfer effect.

For achieving the above object, the utility model provides following technical scheme: the condensation hot water boiler of the collapsible layout of a kind of three backhaul, comprise base and be placed in the boiler body on base, burner, described burner is positioned at the top of boiler body, and enter burner hearth through the smoke-box inwall in the middle of front smoke chamber, the afterbody of described boiler body is provided with outlet flue, described boiler body comprises high temperature section housing, flue, high temperature section smoke pipe and low-temperature zone housing, front tube sheet, back tube sheet, low-temperature zone smoke pipe, the high temperature section smoke pipe of the coated flue of described high temperature section housing and furnace gall periphery, described high temperature section housing sets out water pipe, welding front tube sheet in described low-temperature zone housing, back tube sheet and the welding equipment low-temperature zone smoke pipe between front tube sheet and back tube sheet, the front end of described low-temperature zone housing connects water inlet pipe, the entrance of water inlet pipe is arranged on that one end near front tube sheet, rear end arranges the bottom that tube connector connects high temperature section housing, described low-temperature zone housing and described high temperature section housing are horizontal and collapsible layout.In housing, working media is water.

Housing is divided into high temperature section housing and low-temperature zone housing by the utility model, and both are horizontal and collapsible layout, make boiler compact overall structure, reduces floor space.

Combustion gas and air mix in burner, enter in burner hearth and carry out ignition and combustion, turn back 180 ° flow through the high temperature section smoke pipe of the second backhaul at flue rear portion, and turning back downwards after 180 ° in front smoke chamber flows through low-temperature zone smoke pipe again, then from afterbody outlet discharged to air.

Water inlet enters low-temperature zone housing from water inlet pipe, in the past the rear portion of low-temperature zone housing is flowed to, then entered high temperature section housing in the rear end of low-temperature zone housing by tube connector, flow from back to front in high temperature section housing, then entered the hot-water heating system of applying unit by outlet pipe.

High-temperature flue gas when its temperature is the highest through the high temperature section smoke pipe of flue, the second backhaul, thermal release is passed to corresponding heating surface, now flue-gas temperature reduces through low-temperature zone smoke pipe, and low-temperature zone smoke pipe water inlet for temperature minimum time water, now greatly, heat transfer effect is high for flue-gas temperature and inflow temperature difference; Then enter flue through certain stove water heated up, the flue-gas temperature of flue is the highest, then now flue-gas temperature and inflow temperature difference greatly, heat transfer effect is high.This process stove water absorbs heat from heating surfaces such as flue, high temperature section smoke pipe, low-temperature zone smoke pipes in flow process.The waste heat boiler of feeding in release flue gas can be made to absorb completely, and flue gas reaches condensing state before discharging boiler, thus significantly improves boiler thermal output.

Further, described low-temperature zone housing rearwardly tilts, and has certain angle of inclination with high temperature section housing.

Further, in described low-temperature zone housing, some dividing plates are evenly set, some dividing plates are all serially connected on N root fixed bar, one end and the back tube sheet of described fixed bar are welded and fixed, the shape of described dividing plate is that one piece of arc length is greater than the arc of semicircle, described dividing plate is staggered serial connection up and down, forms corrugated water stream channel.Dividing plate can be 3,4,5 pieces, and N root selected as required by fixed bar, N be more than or equal to 1 natural number.

Low-temperature zone housing is rearwardly tilted to down, is beneficial to cold water flow, and cold water flow track is by waveform flowing, extends cold water flow process, allow cold water and smoke pipe surface comprehensively, contact heat-exchanging equably, lifting heat transfer effect.

The utility model takes above-mentioned corrective measure, and its beneficial effect is remarkable:

1, boiler is divided into high temperature section and low-temperature zone, the stove coolant-temperature gage of low-temperature zone, lower than the stove coolant-temperature gage of high temperature section, makes the stove coolant-temperature gage of the flue-gas temperature and low-temperature zone flowing through low-temperature zone form the larger temperature difference, thus reduces exhaust gas temperature rapidly, reach condensation effect, finally improve boiler thermal output.

2, low-temperature zone smoke pipe adopts " water bag fire " structure, makes compact conformation and can improve heat-transfer effect.

3, the collapsible arrangement of shell high temperature section and low-temperature zone, makes boiler compact overall structure, reduces floor space.
