Description
Technical field
The utility model belongs to technical field of water heaters, relates to the water heater that a kind of waste heat is fully utilized.
Background technology
Existing water heater on the market has the water heater of gas heater, fuel-oil water heater, burning coal or burning firewood etc., all be to adopt single heat exchanger gas that cold water is heated, heat exchanger is a disposable thermal exchange heater, reaches the purpose of heating water temperature through the heat exchanger around the combustion chamber by making cold water.For gas heater capacious, because the water heater water flow is big, the also corresponding increase of the volume of heat exchanger, the firepower by-pass cock of water heater need be transferred to " big fire " shelves when use winter, could satisfy the water temperature requirement by the quantity combusted that increases imflammable gas, the imflammable gas of consumption is bigger, because that combustion gas and heat exchanger carry out the distance of heat exchange is shorter, the EGT height of discharging has caused energy waste; If the water heater capacity is less, heat exchanger is corresponding also less so, though do not need like this firepower by-pass cock of water heater is transferred to " big fire " shelves, but water flow is little, when increasing water yield,, do not reach relevant temperature because it is not enough to add heat, and the EGT that discharge this moment still can be high more a lot of than water temperature in the water inlet pipe, also caused the waste of energy to a certain extent.
The utility model content
Technical problem to be solved in the utility model is the bigger shortcoming of energy waste that exists in the existing water heater, thus the water heater that provides a kind of waste heat that can effectively improve heat exchange benefit energy savings to be fully utilized.
The technical scheme that solution the utility model technical problem is adopted is that the water heater that this waste heat is fully utilized comprises heat exchanger shell, burner, be connected with water inlet pipe, outlet pipe, smoke discharge pipe on the heat exchanger shell, combuster, heat exchanger in the housing, heat exchanger is communicated with outlet pipe, at least be equipped with a residual-heat exchanger between heat exchanger and the smoke discharge pipe, the water inlet end of residual-heat exchanger is communicated with water inlet pipe, and its water side is communicated with the entrance point of heat exchanger.The structure of described residual-heat exchanger can be identical with heat exchanger, also can be inequality.Burner can be the burner of combustion gas or fuel oil, also can be the burner hearth that burns coal or burn firewood.
Preferably, residual-heat exchanger has a plurality of from top to bottom successively, two adjacent residual-heat exchangers are connected by water inlet pipe and water outlet pipe, and the water inlet end of the residual-heat exchanger of the superiors is communicated with water inlet pipe, and undermost residual-heat exchanger water side is communicated with the heat exchanger water inlet end.
Because hot gas is to rising, the higher waste gas of temperature that in heating hypomere heat exchanger, produces, by residual-heat exchanger the time, come the preheating residual-heat exchanger by heat exchange again, and residual-heat exchanger is communicated with water inlet pipe, make outside cold water at first carry out preheating, just enter heat exchanger then through residual-heat exchanger.When adopting a plurality of residual-heat exchanger, outside cold water is during from top to bottom successively by a plurality of residual-heat exchanger, the inflow temperature of each heat exchanger of hypomere is the leaving water temperature of the preceding paragraph through preheating, and every section all is to heat on the basis of epimere leaving water temperature again like this.
Through the leaving water temperature of residual-heat exchanger after heating, more much higher than the leaving water temperature of single employing heat exchanger, therefore gas consumption of the present utility model lacks much than the general gas water heater, has energy-efficient characteristics.The utility model water heater can be used to shower that hot water is provided, and also can provide thermal source for heating.
Description of drawings
Fig. 1 is a kind of gas heater example structure schematic diagram of the present utility model
Among the figure: 7-heat exchanger, the 8-smoke discharge pipe of 1-water inlet pipe, 2-outlet pipe, 3-burner, 4-residual-heat exchanger, 5-heat exchanger shell, 6-combustion chamber
The specific embodiment
Below in conjunction with a kind of gas heater embodiment and accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises housing 5, is connected with water inlet pipe 1, outlet pipe 2, smoke discharge pipe 8 on the housing 5, combuster 6 and heat exchanger 7 in the heat exchanger shell 5, burner 3 is arranged at 6 bottoms, combustion chamber, has gas inlet pipe to be connected with burner.Heat exchanger 7 is communicated with outlet pipe 2, is equipped with a residual-heat exchanger 4 between heat exchanger 7 and the smoke discharge pipe 8 at least, and the water inlet end of residual-heat exchanger 4 is communicated with water inlet pipe 1, and its water side is communicated with the water inlet end of heat exchanger 7.
Preferably, residual-heat exchanger 4 has a plurality of from top to bottom successively, two adjacent residual-heat exchangers are connected by water inlet pipe and water outlet pipe, and the water inlet end of the residual-heat exchanger 4 of the superiors is communicated with water inlet pipe 1, and the water side of undermost residual-heat exchanger 4 is communicated with the water inlet end of heat exchanger 7.Each residual-heat exchanger (4) under tap into water pipe, on pick out water pipe.Residual-heat exchanger 4 is fixed in the heat exchanger shell 5 as heat exchanger 7.The structure of residual-heat exchanger can be identical with heat exchanger, also can be the residual-heat exchanger of making after the part that stretches into the combustion chamber in the existing heat exchanger 7 is removed 4.
Embodiment 1:
5.5 liters of gas heaters are reequiped, increase a residual-heat exchanger 4 within it between the heat exchanger 7 of portion and the smoke discharge pipe 8, the water inlet end of residual-heat exchanger 4 is communicated with water inlet pipe 1, the water side of residual-heat exchanger 4 is communicated with the water inlet end of heat exchanger 7, the structure of residual-heat exchanger is identical with heat exchanger, promptly forms the utility model.
Under same discharge, (make the water heater discharge switch of repacking front and back be located at same position), water heater before the repacking need be located at the firepower switch leaving water temperature that " big fire " shelves (the firepower switch is divided into " big fire ", " moderate heat ", " little fire " third gear in water heater) burn and just can reach, after repacking the utility model into, just can reach same water outlet water temperature with the burning of " moderate heat " shelves firepower; And the leaving water temperature that former usefulness " moderate heat " shelves firepower can reach just can reach with " little fire " shelves firepower after repacking.That is to say, for improving the 6-8 degree with the gas heater before the comparable repacking of shelves firepower repacking back leaving water temperature.
Residual-heat exchanger 4 also can adopt a plurality ofly in the present embodiment, and the concrete quantity of the residual-heat exchanger that is adopted will must be higher than the into temperature of water according to the waste gas outlet temperature that makes smoke discharge pipe 8 places, takes traffic requirement simultaneously into consideration and the cost problem is determined.
