Description

The high effect forced exhaust gas displacement type water heater of condensation

Technology neck city

The utility model relates to a kind of gas displacement type water heater, particularly a kind of high effect forced exhaust gas displacement type water heater of condensation that can improve fume emission behind the fuel gas buring, be beneficial to environmental protection.

Background technology

Along with the continuous development of science and technology, the improvement day by day of people's living standard, the demand of hot water in people's daily life increases greatly, and water heater, gas heater are extensive use of by people, and especially gas displacement type water heater has been come into huge numbers of families gradually.It adopts the burning of combustion gas, water in the inner bag is carried out heat temperature raising, but because gas displacement type water heater inner bag heat-transfer surface is little, the high-temperature flue gas flow process that burning produces is short, flue gas exhaust gas temperature height, forfeiture part heat can not make full use of, thereby cause complete machine working heat efficient low, the heat production outlet capacity is low in unit interval, and insulation maintaining heat load is higher, thereby produce certain thermal waste, thereby a kind of condensing type highly effective gas displacement type water heater appearred, heat energy that its burning discharges and high-temperature flue gas at first carry out a heat exchange by the inner bag lower cover transmission of inner bag combination, subsequently under the delay effect of the stagnant sheet of flue, carry out the secondary heat exchange with inner bag combination middle part smoke exhaust pipe again, waste heat by the secondary heat exchange and high-temperature flue gas are after the smoke exhaust pipe upper port is hampered by adverse current cover top cover, reverse downwards by the adverse current cover, in the adverse current chamber, carry out heat exchange once more with the enamel inner container outer wall, waste heat and high-temperature flue gas are fully absorbed, reduce to the following flue gas of water vapour dew-point temperature when driving in the wrong direction to the enamel inner container bottom, be hampered by the ponding dish, flue gas rotary upwards, back cavity by reflux cover and the hood-shaped one-tenth of adverse current, flue gas is once more by the contrary back cavity top that is back to of back cavity, be hampered by the cover sealing ring that refluxes, at this moment, the flue gas of accumulation is again by covering the smokejack that the front upper mouth links to each other with backflow, the exhaust smoke hole of corresponding via hole on the shell and front shroud two upper lateral parts directly drains into outside the water heater.Since its gas fume after burning directly from the middle part of gas heater to space drainage, so such water heater install and use the environmental requirement strictness, must be installed in draughty environment, otherwise will influence the air quality of environment for use.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of existing gas displacement type water heater, provide a kind of condensation high effect forced exhaust gas displacement type water heater, it is simple in structure, safe in utilization, it is outdoor that gas fume after burning is drained into, reduce the environmental requirement that it is installed and used, can be installed in the indoor ambient air quality that also do not influence.

For realizing that the purpose of this utility model has adopted such technical scheme: the high effect forced exhaust gas displacement type water heater of a kind of condensation, include the inner bag combination, anodic magnesium rod, smoke pipe, the flue sheet that stagnates, smokejack, heat-insulation layer, the support ring combination, outer casing upper cover, shell, the combination of shell lower cover, the front shroud combination, water supply connector, water out adapter, the condensed water joint, temperature, pressure safety valve joint, the adverse current cover, cover refluxes, the cover sealing ring refluxes, the ponding dish, the ponding dish props up seat ring, the main burner assembly, gas control valve, adverse current cover transition circle, adverse current cover top cover, solar energy circulating backwater joint, solar energy cyclic water outlet joint, it is characterized in that being installed with air exhauster at the middle part of aforementioned outer casing upper cover upper surface, outside aforesaid shell a side in, top is provided with enclosure, the lower end of enclosure and the outlet of aforementioned smokejack are led to, the upper end of enclosure is provided with an exhaust fume collecting hood, and aforementioned air exhauster is fastened in the exhaust fume collecting hood, the exhaust outlet of air exhauster is located at outside the exhaust fume collecting hood, and the exhaust outlet of air exhauster is connected with the smoke discharging pipe of peripheral hardware.

By the high effect forced exhaust gas displacement type water heater of condensation that the utility model provides, in the water heater course of normal operation, the required air that burns enters in the combustion chamber by the via hole in via hole on front shroud both sides air vent, the shell and the support ring combination; The stagnant sheet of flue is contained in the smoke pipe at inner bag combination middle part, the smoke pipe upper port has adverse current cover top cover, heat energy that its burning discharges and high-temperature flue gas at first carry out a heat exchange by the transmission of inner bag combination lower cover, under the delay effect of the stagnant sheet of flue, the smoke pipe in making up with inner bag again carries out the secondary heat exchange subsequently; Waste heat by the secondary heat exchange and high-temperature flue gas are after the smoke pipe upper port is hampered by adverse current cover top cover, reverse downwards by the adverse current cover, in the adverse current chamber, carry out heat exchange once more with inner bag combination outer wall, the heat of waste heat and high-temperature flue gas is fully absorbed, reduce to the following flue gas of water vapour dew-point temperature when driving in the wrong direction to inner bag combination bottom, be hampered by the ponding dish, flue gas rotary upwards, back cavity by reflux cover and the hood-shaped one-tenth of adverse current, flue gas is once more by the contrary back cavity top that is back to of back cavity, be hampered by the cover sealing ring that refluxes, at this moment, the flue gas of the accumulation smokejack by linking to each other again with mouth on the cover that refluxes, enclosure on the shell outside, the air exhauster in enclosure is enforceable extracts the flue gas in the enclosure out, and, drain into the low temperature exhaust heat flue gas outdoor by the exhaust outlet of air exhauster smoke exhaust pipe by peripheral hardware.Of the present utility model simple in structure, safe and reliable, it is outdoor that gas fume after burning is drained into, and reduces the environmental requirement that it is installed and used, and is installed in the indoor ambient air quality that also do not influence.
