Abstract
The utility model relates to a water temperature preheating device of a gas water heater, comprising a water heater, a water-heater water inlet, a water-heater water outlet, a gas inlet and a flue. The preheating device is characterized in that a sleeve pipe is arranged out the flue, and the end surfaces of the left head and the right head between the sleeve pipe and the gas pipe are closed. A level baffle plate is arranged in the space between the sleeve pipe and the flue, and a closed cavity is divided into an upper chamber and a lower chamber. One end of the upper chamber is provided with an upper chamber water inlet which is directly connected with a tap water pipe, and the same end of the lower chamber is provided with a lower chamber water outlet. The baffle plate of the other end of the cavity is provided with a draining passageway which is used for communicating the upper chamber with the lower chamber, and the lower chamber water outlet is connected with the water-heater water inlet by a water pipe. Tap water enters from the upper chamber water inlet, then flows to the lower chamber by a water flow passageway, and finally flows out from the lower chamber water outlet to enter into the water heater. The water temperature preheating device of the gas water heater utilizes the high temperature of the flue to preheat the tap water, so gas is saved, and the using cost is effectively reduced.

Background technology
Along with the develop rapidly of current science and technology, unprecedented rapid growth situation has appearred in energy demand, and prices such as oil, natural gas are sharply soaring, and global energy is in short supply, and the cry of energy-saving and emission-reduction can be heard without end.Investigate discovery at the gas heater that numerous town dwellers use: at present, what a lot of residents used is old-fashioned gas heater, because service time is relatively permanent and the problem such as functional of water heater, cause the exhaust gas temperature of these water heaters very high, the tube wall of chimney is also very boiling hot, heat energy is run off in a large number, both increased use cost, shortened the service life of machine again.So, be badly in need of the smoke exhaust pipe of these gas heaters is transformed, better reclaim and utilize waste heat to come for the mankind benefit, reduce air pollution, realize energy-saving and emission-reduction.
Chinese patent: application number 200810029950, applying date 2008.08.04, disclosing a kind of condensed type combustion gas water heater, is a kind of fast water heater that obvious heat of smoke and two thermals source of steam latent heat are all used, and has the higher thermal efficiency than traditional gas instantaneous water heater.It has two heat exchangers, except that sensible heat exchanger with general gas water heater, more than a condensing heat exchanger.Two parts heat stack by sensible heat exchanger and condensing heat exchanger gained makes its thermal efficiency far above common water heater.But the condensed type combustion gas water heater price is too high, and power consumption is more.Under so high cost, the gas quantity that it can be saved very little.Calculate not as good as buying general gas heater.Have technology in vain, but can't bring considerable economic.The resident buys use can not reach the purpose of cutting down expenses.So, need the development new technologies product to reach the win-win of energy conservation and economic benefit.
The utility model content
The utility model discloses a kind of water temperature preheating apparatus of gas heater, by smoke exhaust pipe is transformed, reach the purpose of preheating water temperature, thereby to overcome existing gas heater exhaust gas temperature height, the waste heat drawbacks such as aggravation environmental pollution, shortening heat hydrophone service life of can not utilizing, waste energy.
A kind of water temperature preheating apparatus of gas heater, comprise water heater, the water heater water inlet, the water heater delivery port, fuel gas inlet and smoke exhaust pipe, it is characterized in that: described preheating apparatus is to add sleeve pipe at smoke exhaust pipe, left side between sleeve pipe and the smoke exhaust pipe, right two annular end face is airtight, make the interior pre-warmed water of annular space not excessive, in the annular space between sleeve pipe and the smoke exhaust pipe horizontal baffle is set, airtight annular space is divided into, following two chambers, one end of upper chamber has upper chamber's water inlet, directly be connected with running water pipe, the same end of lower chambers has the lower chambers delivery port, on the baffle plate in the other end annular end face drainage channel is set, upper chamber is communicated with lower chambers, the lower chambers delivery port is connected with the heater inleting pipe through water pipe, after running water is entered by upper chamber's water inlet, flow toward lower chambers by water stream channel, flow out by the lower chambers delivery port at last, enter water heater, utilize the high temperature of smoke exhaust pipe, realize preheating running water.
Affixed cross inserted sheet in the described smoke exhaust pipe.
Described cross inserted sheet is the welding of thin plate quadrature, is used to strengthen the radiation heat transfer and the heat convection heat of flue gas.
The utility model is made the form of chuck with traditional water heater smoke exhaust pipe, and is installed into the mouth of a river and delivery port at the same end of chuck, and water inlet connects running water pipe, and delivery port connects the gas heater water inlet.In chuck, feed running water, utilize heat-transfer effect to absorb the part heat of the high-temperature flue gas of water heater discharge, thereby improve the temperature of running water in the pipeline, thereby the water temperature of gas heater water inlet is raise, be heated under the equal temperature condition, the energy that water heater consumed has reduced.
The waste heat that the utility model makes full use of smoke exhaust pipe is the water preheat that enters gas heater, has improved the water temperature that enters water heater, has both reduced the smoke exhaust pipe temperature, well reached the purpose of utilizing waste heat, save combustion gas again, effectively improved the utilization ratio of energy, reduced use cost.
