A kind of condensed-water recovering device
The utility model is established and is doubted a kind of condensate treatment facility, particularly a kind of condensed-water recovering device.
In recent years, the enhancing gradually of Along with people's awareness of saving energy, various places are paid attention to the recovery of steam condensate (SC) to some extent, but compare with boiler and water treatment in the heating system, are still comparatively weak link.
Generally speaking, the steam condensate that condensation water recovery system recovered steam system discharges can maximally utilise the heat of steam condensate, using water wisely, fuel savings.The recovery system of steam condensate has open recovery system and closed recovery system at present.
The steam condensate that open recovery system is about to the gas utilization unit discharging is recovered in the uncovered underground tank through ground-based duct is concentrated; Steam that condensate is carried and condensed water because of the normal pressure that reduces pressure after the indirect steam emptying that produces of flash distillation; The remaining condensate near 100 ℃ cools to below 70 ℃ naturally, exports water use sector to pump again.Open recovery system is because atmospheric flashing reclaims, and temperature is significantly less than 100 degree, and the matter energy loss is all bigger.
The closed recovery system is that the condensed water of gas utilization unit discharging is concentrated through built on stilts or ground-based duct and is delivered in the airtight recycling can; Utilize the comprehensive retracting device of high-temperature condensation water with the output of the condensate more than 100 ℃ then, form a closed-cycle system from steam supply to recovery.With respect to open recovery system, the quantity of steam of closed recovery system emptying is less or be zero, more solves the energy, therefore becomes steam condensate way of recycling preferably.When but existing closed recovery system reclaims the steam condensate of multiply different pressures at the same time; Operating pressure in the recycling can only be the pressure less than minimum one steam condensate of pressure, but this is concerning the bigger steam condensate thigh of pressure, when getting into recycling can; Inevitably can produce the secondary flash distillation; And this flash-off steam does not have recovery measure, necessary emptying, and matter and energy is all lost.
The utility model content
The utility model purpose: the utility model provides a kind of condensed-water recovering device that can eliminate 2 flash distillations to the deficiency of prior art.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to explain.
The utility model discloses a kind of condensed-water recovering device, comprise the dewatering capacity-enlarging device 1, Condensate recovery device 2 and the collecting-tank 3 that are communicated with successively through pipeline; Connection place of said dewatering capacity-enlarging device 1 and Condensate recovery device 2 is provided with fast-discharge valve 5, and fast-discharge valve 5 is provided with fast row's ball float 4; Be provided with water pump 7 and induction apparatus 8 successively on the connecting pipe of said Condensate recovery device 2 and collecting-tank 3; Said Condensate recovery device 2 bottoms are provided with cavitation cancellation element 6, and cavitation cancellation element 6 is arranged on Condensate recovery device 2 and water pump 7 import connecting places; Said dewatering capacity-enlarging device 1 is provided with a secondary vapour recovery tube 9 and is connected with induction apparatus 8.
When the utility model uses; Behind the dewatering capacity-enlarging device at condensed water in high temperature access arrangement top; Condensate liquid level in flash vessel constantly rises, and can float hydrophobic fast row's ball float when liquid level rises to certain altitude, and the valve that draws back fast arranging device simultaneously makes condensate enter water storage box.The water storage box bottom is provided with the cavitation cancellation element, and cancellation element links to each other with the water pump import, and secondary vapour injection absorption plant is equipped with in the feed pump outlet, and the dewatering capacity-enlarging device is established a secondary vapour recovery tube and linked to each other with induction apparatus.When operation, condensate is seen off by water pump, through secondary vapour induction apparatus the secondary flash steam in the dewatering capacity-enlarging device is taken away, and reaches the purpose of energy-conservation recovery condensed water in high temperature.
The utility model provides a kind of thinking and method of condensed-water recovering device; The method and the approach of concrete this technical scheme of realization are a lot; The above only is the preferred implementation of the utility model, should be pointed out that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model, and all available prior art of each part not clear and definite in the present embodiment realizes.
