Description
Technical field
The utility model relates to a kind of water heater that is used to fire the domestic hot-water, particularly exchange type energy-saving hot water stove.
Background technology
The hot water of purposes such as the relatively large unit a large amount of confessions of needs every day such as bathhouse, school, enterprises and institutions, factories and miness are drunk, shower is generally provided by hot-water boiler, sluggard's stove etc.These boiler design are unreasonable at present, and fuel combustion tail gas directly discharges, and the heat of flue gas fails rationally to utilize, and the thermal efficiency is lower, the energy consumption height.
Summary of the invention
The purpose of this utility model provides the high exchange type energy-saving hot water of a kind of thermal efficiency, to reach energy saving purposes.
This water heater comprises that combustion chamber, blower fan and water tank, water tank are provided with cold water inlet tube, said water tank comprises main water box and the secondary water tank that links to each other with communicating pipe, main water box is placed on the separate type combustion chamber, the top of major and minor two water tanks is provided with the collection chamber of intercommunication, is respectively equipped with a plurality of fume pipes in two water tanks; The fume pipe of main water box is connected between combustion chamber and the collection chamber, and the fume pipe of secondary water tank is connected between collection chamber and the discharge flue, and blower fan is located at the outlet of discharge flue; Be provided with the hot water jacket around the said combustion chamber, hot water jacket's one side is provided with the water inlet that can link to each other with main water box and takes over, and opposite side is provided with the hot water outlet pipe.
Be connected in the top that is connected to two water tanks communicating pipe between set main water box and the secondary water tank.
Communicating pipe be provided with overflow pipe between said main water box and the secondary water tank.
Said overflow pipe is provided with liquid level display.
Secondary water tank is provided with ash hole.
Major and minor water tank is provided with heat-insulation layer.
The combustion chamber top is provided with the heating pipe who radially connects with the hot water jacket.
The combustion chamber is provided with coal filling hole, and the bottom is provided with the cinder outlet.
This exchange type energy-saving hot water stove injects cold water from the cold water inlet tube of secondary water tank, the hot flue gas of combustion chamber is upwards by the main water box fume pipe, feed main water box collection chamber, secondary water tank collection chamber, secondary water tank fume pipe successively, last under the suction of exhaust blower, discharge in the atmosphere by the smoke exhaust pipe of the bottom of secondary water tank.In this process, cold water at first with the flue gas heat exchange of secondary water tank, temperature is preheating to 50～60 ℃, enter main water box then, be heated to 60～70 ℃ by high-temperature flue gas, enter the hot water jacket then, the water in the chuck further absorbs the burner hearth heat, and heated by the burner hearth High Temperature Gas by the heating pipe who radially connects, emit high-temperature-hot-water from the hot water outlet pipe's of a side water valve.The cold water of this water heater by low temperature to high temperature; Hot flue gas by high temperature (about 900 ℃) to low temperature (about 100 ℃), can keep the rational temperature difference between the water of two ends, the gas, thereby the heat that can make full use of the fuel combustion flue gas carries out heat exchange, and the heat of flue gas is farthest reclaimed, and reaches energy-conservation purpose.
