Abstract
The utility model relates to a heat recovery and air ventilating device for domestic gas water heaters, comprising an air ventilating housing connected with an air exhaust pipe, and the air ventilating housing is provided with a waste heat collector. When the exhaust gas of the gas water-heater passes through the waste heat collector, the exhaust gas is carried out the heat exchange with the cold water in the waste heat collector. The water flows into the water inlet of the gas water-heater when the water temperature is raised, so the water entering the gas water-heater has higher temperature, and the energy is saved. The exhaust gas with CO, C O 2 and low temperature is exhausted to the outdoor though the exhaust pipe. So the indoor air cleanliness and the personal safety are ensured.
Description
Technical field is energy-conservation under the utility model, and air exhausting device relates in particular to design or be installed in the hood on the various gas heater exhaust outlets.
The present various combustion gas of China (natural gas, artificial coal gas, liquefied petroleum gas etc.) water heater, the waste gas after right the burning all are directly to be emitted on indoorly, contain a large amount of CO in the waste gas
2With the CO pernicious gas, polluted indoor air.Especially install and use improper or the room is little, under the situation about drawing badly, can make dizziness, heavy poison, harmful health of human body, the EGT of Pai Chuing is higher in addition, and a large amount of heats are failed utilization in the waste gas, and being dissipated in the air in vain.
The purpose of this utility model is the problem that exists at prior art, and the backheat air exhausting device of a kind of gas heater of innovation and creation, it can have a style of one's own and be installed on the exhaust outlet of home-use various gas heaters, also can adopt in the design of gas fired water heater.
This device is after it can make the waste gas of gas heater carry out heat exchange by waste-heat recoverer, waste heat in the waste gas is further recycled, waste gas arrives outdoor by discharge of pipes then, water in the waste-heat recoverer enters the gas heater water inlet after heating up, so neither pollute room air, guarantee health of human body, improved the thermal efficiency of gas heater again, save the energy.
The purpose of this utility model is achieved in that this device has a hood shell, and cover top portion has exhaust outlet to be connected with discharge duct, and waste-heat recoverer is housed in the hood.Running water enters the waste gas generation heat exchange of waste-heat recoverer and gas heater, water in the waste-heat recoverer absorbs heat water temperature rising in the waste gas, then from the water inlet of gas heater enter pipeline further heat absorption reach required temperature, flow out from the gas heater delivery port, to satisfy people's needs.So both improved the utilization rate of heat energy, it is outdoor that the waste gas of gas heater is delivered to by the discharge duct of this device, guaranteed the safety of the indoor air clean and the person.
Following embodiment of concrete structure of the present utility model and accompanying drawing provide.
Accompanying drawing
The positive cross-sectional schematic of Fig. 1 domestic gas-fired water heater backheat air exhausting device
Fig. 2 domestic gas-fired water heater backheat air exhausting device A-A section schematic top plan view
Describe structure of the present utility model and operation principle thereof in detail below in conjunction with accompanying drawing.
Domestic gas-fired water heater backheat air exhausting device is made of following several sections.It has the hood shell 1 of an epicone below, an exhaust outlet 2 is set on the top of shell 1 and is connected with blast pipe 3, waste-heat recoverer 4 is housed in the shell 1, and the coiled pipe 6 that waste-heat recoverer 4 can adopt coiled pipe 6 or be added with heat absorption fin 5 constitutes (sees Fig. 1, Fig. 2).Coiled pipe 6 can be one deck, upper and lower two layers or three layers of arrangement.There are screw 7 or magnetic patch 8 in hood shell 1 bottom for four jiaos, so that be installed on the gas heater.Flow backwards for fear of outdoor air, plate-turning door 9 is equipped with at 2 places at exhaust outlet, and when gas water heater working, plate-turning door 9 is parallel to discharge duct 3, so that be discharged to outdoor by pipeline 3 waste gas.Defend 10 and make the turnover panel shop front 9 vertical in order to prevent that outdoor air from flowing backwards then to rotate to draw, promptly close discharge duct 3 with the discharge duct axle.If it is little that the room of gas heater is installed, condition is poor, can install small electric fan in hood, to force exhaust.
When starting gas heater, running water at first enters waste-heat recoverer, by coiled pipe inlet 11, flow to lower floor's coiled pipe 6 from upper strata coiled pipe 6, and simultaneously carry out heat exchange with the waste gas of gas heater, and absorb its waste heat, water temperature is raise, flow into gas heaters by coiled pipe outlet 12 then, and the waste gas of gas heater since with coiled pipe 6 in water carry out heat exchange and temperature reduces the back and is discharged into outdoor from discharge duct 3.
The utility model is simple in structure, and low cost is easy to use, can save the energy, can make indoor air clean again, guarantees personal safety.It is the indispensable device that gas heater is suitable for.
