Description

The gas-heating water heater is detained recovery method and the device thereof of heat
Technical field
The present invention relates to the gas-heating water heater, is recovery method and device thereof that a kind of gas-heating water heater is detained heat.
Background technology
The gas-heating water heater also claims burnt gas wall hanging furnace, and it has two basic functions, the one, and residence heating, the 2nd, bath hot water, the water route of two kinds of functions is independently.Heating water is to be heated by the hot flue gas behind the fuel gas buring, is called the extreme misery heat exchange; Bath hot water is by heating water it to be heated, and is called the heat exchange of water water.Heat exchange mode has two kinds usually, and a kind of is double pipe heat exchanger, and another kind is plate type heat exchanger, and its principle is basic identical.Double pipe heat exchanger is cover tubule in the bassoon so name is conceived, and tubule is heated after bassoon is heated again.During heating, the water in the bassoon flows, and intratubular water does not flow, and the water in the bassoon is walked heat by the water pump heat-radiation belt that circulates; During bathing, the water in the bassoon does not flow, and intratubular water flows, and heat is taken away in the disposable discharging of intratubular water.When intratubular bathing water stops suddenly, heating also stops thereupon, but the hot temperature of delay of water is also very high in heat exchanger and the bassoon, need start water pump and blower fan at once, the delay heat of water is lowered the temperature in heat exchanging device and the bassoon at once, to avoid intratubular water to be detained the thermal inertia heating, cause tubule water temperature too high scald people or produce the gasification phenomenon to cause the accident.So the back cleaning of gas-heating water heater has just become the requisite working procedure of current domestic and international gas-heating water heater.The delay heat of being swept is by out in the cold always as normal phenomenon.
The every startup heating of gas-heating water heater once, blower fan just must carry out once back cleaning, each back cleaning time is that 10-100 does not wait second, rough calculation, single delay heat that emits with regard to blower fan, at every turn at least more than 200W, at least will start operation more than 10 times every average every day in gas-heating water heater summer in winter, the heat that emits every day is at least more than 2000W, be roughly equal to the natural gas more than 0.2 cubic metre, every gas-heating water heater will discharge the natural gas that slatterns more than 73 cubic metres every year, and direct economy is wasted about more than 150 yuan.Existing gas-heating water heater is tens million of in the world, and China also has millions of, and increases with annual more than 120 ten thousand speed.The conservative calculating of the direct economic loss that produces thus surpasses more than 200,000,000 yuans, also is very huge to the destruction of environmental protection, and this does not wherein also count the waste of electricity consumption.
Summary of the invention
The objective of the invention is, overcome the prejudice of prior art, put forth effort on the problem that the gas-heating water heater is detained the recuperation of heat utilization that solves, provide a kind of scientific and reasonable, practical, good economy performance, the gas-heating water heater that can more effectively take full advantage of the energy is detained the recovery method of heat; And provide the realization said method used device.
Realize that the technical scheme that the object of the invention adopts is, a kind of gas-heating water heater is detained the recovery method of heat, it is characterized in that it comprises following content:
