Hot water storgae is improved hot water storgae shown in the accompanying drawing 2, is the energy with the saturated vapor, and thermal source is the plate-sheet-type heater, is the hot water storgae with the radiant heat method heating.Its thermal condition stable state is as follows: the trough inner water position remains on the cell body depth value, saturated vapor feeds heater, relies on the plate conduction heat on the heater, with heating of trough inner water body and maintenance operating temperature, local water body is the pool boiling state, and unnecessary steam and condensed water are discharged from discharge tube; Simultaneously, the interior high-temperature water of groove still constantly overflows groove and runs off outward, and the normal temperature fresh water still need inject in the groove, and just atomizing steam no longer occurs.Because there is the very easily shortcoming in crack of seal perimeter in the plate-sheet-type heater, in case produce the crack, saturated vapor directly injects water body again, and atomizing steam is inevitable again, and the whole defectives and the problem of injection method heating still exist.

Use the hot water storgae of electric energy heating, thermal source is the electric energy original paper, be the hot water storgae with the radiant heat method heating, the hot water storgae of automatic temperature control is arranged, its thermal condition stable state is very good, there are not aforesaid defective and problem, but, there is not the hot water storgae of automatic temperature control, its thermal condition stable state is still relatively poor, except that atomizing steam no longer produced, the defective and the problem of saturated vapor heating still existed.

The purpose of this utility model is: improve the utilization rate of saturated vapor and fresh water thereof, prevent because of the under-utilized atomizing steam that produces of saturated vapor and the loss of high-temperature water, with energy efficient with improve workshop internal and external environment condition and safety operation condition.The utility model adopts novel structure and changes the approach of thermal condition stable state, achieves the above object.

The utility model is the natural recirculating type hot water storgae that a kind of external power-free drives, and its structure as shown in Figure 3.Comprise cell body, boiling water chamber and circulation line, upper and lower circulation pipe fuses cell body and boiling water chamber, and thermal source places boiling water indoor, is laid with part flow arrangement in the cell body.Between cell body (1) and boiling water chamber (4) upper cycling mouth, connect with upper circular tube (3), or an end of upper circular tube and boiling water chamber upper cycling mouth join, the other end directly feeds in the groove, feed upper circular tube one end in the groove, all should be connected mutually with part flow arrangement (2), part flow arrangement has isocon, flow distribution plate etc.; Between the circulation port, using down, circulation pipe (5) connects under cell body and the boiling water chamber.

Thermal condition stable state of the present utility model is as follows: earlier fresh water is injected hot water storgae, make the interior water level of cell body reach about 3/4ths of the cell body degree of depth, then, thermal source heats the indoor water body of boiling water, and remains violent pool boiling state, boiling water flow through naturally upper circular tube and part flow arrangement, be evenly distributed in the cell body, with the equivalent water body circulation pipe of flowing through down naturally, return the boiling water chamber in the cell body, continue to be heated into boiling water, finish once circulation.In the heating process, water body remains continuous, Natural Circulation state closed, equivalent, and the water body in the hot water storgae is heated, and make the interior water temperature of cell body keep nearly boiling point operating temperature, in case stop heat supply, the indoor water body of boiling water stops boiling, and circulation also stops immediately.In water body heating and cyclic process, no atomizing steam produces and high-temperature water runs off, and also need not inject the normal temperature fresh water.Its energy is saturated vapor, also can use electric energy.
