The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.

As shown in Figure 1, a kind of steam generator with evaporation-cooled device, comprise: vaporium 1, the combustion chamber 2 of vaporium 1 below, the waste-heat recovery device 4 that connects combustion chamber 2, high-temperature flame-proof wall 5 outside the combustion chamber 2, the moisturizing passage 11 that is communicated with waste-heat recovery device 4 and vaporium 1, the thermal insulation separation thermosphere 6 of vaporium 1 and 2 peripheries, combustion chamber, steam (vapor) outlet 10 also comprises the condensation chamber 3 of vaporium 1 top, also comprise the low liquid level sensor 7 in the vaporium, high liquid level sensor 8, the liquid level alarm 9 that vaporium is outer, the water inlet pipe 14 and valve 13 of connection condenser.

Further, described waste-heat recovery device 4 comprises the gas outlet 403 that connects combustion chamber 2, the smoke chamber 401 that communicates with gas outlet 403, the appearance water device 402 outside the smoke chamber 401, the chimney 404 of connection smoke chamber 401.The tail gas that combustion chamber 2 ejects entered gas outlet 403 and arrived smoke chambers 401, utilized the temperature of tail gas to add the water of 402 li in thermal capacitance water device, realized the recovery of tail gas heat quantity, finally by the tail gas after the supercooling by chimney 404 exhaust steam machines.

Further, described condenser 3 comprises that feed tube 302 that a hollow water pipe 301, communicates with thermal insulation separation thermosphere 6 and steam outlet pipe 303, connect the water pipe 12 of waste-heat recovery devices 4.Evaporative cooling medium in the thermal insulation separation thermosphere 6 is heated, be vapour phase from liquid phase transition, and enter condenser 3 by steam outlet pipe 303, because the water temperature in the hollow water pipe 301 is lower, evaporative cooling medium changes liquid phase into from vapour phase again, and from feed tube 303 inflow thermal insulation separation thermospheres 6, same, the water temperature in the hollow water pipe 301 raises.

Further, when the water level in the vaporium is lower than liquid level sensor 7, liquid level alarm 9 sends warning, at this moment opens the valve 13 of water inlet pipe 14, and current arrive waste-heat recovery device 4 through hollow water pipe 301, the water level that holds water device 402 this moment raises, water enters vaporium 1 from moisturizing passage 11, thus the water level of the vaporium 1 that raise, when the water level of vaporium 1 arrives high liquid level sensor 8, liquid level alarm 9 gives the alarm, and closes the valve 13 of water inlet pipe 14.

Further, there are evaporative cooling medium, described evaporative cooling medium must realize gas-liquid conversion, the medium that density is less in the middle of the described thermal insulation separation thermosphere 6.When the temperature of thermal insulation separation thermosphere 6 raise, evaporative cooling medium was heated and becomes vapour phase and enter condensation chamber 3, and the evaporative cooling medium of vapour phase has been realized the transfer of heat with the heating of the water in the hollow water pipe 301.

The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
