Description
Technical field
The invention belongs to heat preservation hot water tank technical field, be specifically related to a kind of Steam Heating thermal storage water tank and hot-water heating system.
Background technology
In daily production and life, in order to save energy consumption, use in a large number heat exchange type heat storage water tank, although these heat exchanger structures are simple, exist heat exchange efficiency low, intelligent level is not high, safeguards the problems such as inconvenient.Conventionally by Steam Heating, adopt Washdown type, exactly steam is directly passed in heated water.But the noise that this method produces is large, and heat exchange efficiency is low, and many occasions are inapplicable, such as pressure-bearing type thermal storage water tank.The greatest problem existing in heat exchanger application process is easily at heat exchanger surface, to produce incrustation scale to form thermal resistance, greatly affected heat exchange efficiency, after the fouling of stainless steel plate type heat exchanger, can take apart to clear up, then assemble use again, but heat exchanger fouling in thermal storage water tank is just inconvenient to clear up.
Summary of the invention
The object of the invention is to propose a kind of Steam Heating thermal storage water tank and hot-water heating system that can effectively prevent that incrustation scale from generating.
Technical scheme of the present invention is achieved in that a kind of Steam Heating thermal storage water tank, comprise water tank and be located at the vapor heat exchanger in this water tank, this water tank is provided with water inlet pipe and outlet pipe, this vapor heat exchanger is provided with steam-gas inlet and condensation-water drain, and described heat exchanger comprises steam heat exchanging tube, is placed in the guard outside this steam heat exchanging tube and is placed in the scale removal matter particle in this guard.
By being provided with a guard and in this guard, a kind of scale removal matter particle being put in the inner and contacted with steam heat exchanging tube intimate on steam heat exchanging tube, make scale removal matter particle can relatively be evenly distributed in the periphery of steam heat-exchanging tube-surface; The dirty preferred growth of separating out from water during heating also can split away off from scale removal matter particle in scale removal matter, is finally deposited to thermal storage water tank's bottom, thereby prevents that steam heat exchanging tube surface scale from affecting heat exchange effect.Because scale removal matter particle has good heat conductive performance, by heat, conduct the surface area that its periphery that is distributed in steam heat-exchanging tube-surface has been equivalent to increase steam heat exchanging tube, further improved heat exchange efficiency.
