Abstract
The utility model discloses a steam condensed water recycling system. The steam condensed water recycling system comprises a dredging valve, a water collecting tank and a condensed water storage tank, wherein the output end of the dredging valve is connected with the water collecting tank, steam condensed water is collected and separated by the water collecting tank, the water collecting tank is connected with the condensed water storage tank, the condensed water is delivered to the condensed water storage tank, and the condensed water in the condensed water storage tank is discharged out of the recycling system by a water pump which is connected with the condensed water storage tank. The condensed water is separated and recycled through the arrangement of the steam condensed water recycling system behind a steam utilizing device. The treatment cost of sewage water is lowered under the condition of reducing pollution, so that the purpose of reducing the waste of resources is achieved.
Description
Technical field
The utility model belongs to chemical technology field, is specifically related to a kind of steam condensate recovery system.
Background technology
Steam is widely used in synthetic ammonia industry, is mainly used in processing medium heat exchange and uses as raw materials technology, and in steam course of conveying, a large amount of drain valves that use are by steam condensate (SC) exhaust steam pipeline.Current most producer lets alone described steam condensate (SC) gravity flow to reclaim.According to statistics: take that to produce 200000 tons of synthetic ammonia installations per year be example, nearly 7 tons of steam condensate (SC)s of being discharged by drain valve per hour, calculate according to annual production for 300 days, waste every year nearly 50,000 tons of desalted water, therefore cause the waste of a large amount of desalted waters and production cost; The condensate temperature of simultaneously discharging due to drain valve is very high, and production plant area fog is curled up, and causes visual pollution, affects plant environment.
Utility model content
The utility model object is to provide a kind of steam condensate recovery system, not only can reduce energy waste, reduces the pollution of condensed water to environment simultaneously.
For achieving the above object, the utility model provides a kind of steam condensate recovery system, comprise drain valve, water leg and condensed water storage tank, described drain valve output is communicated with described water leg by pipeline, this water leg is connected with described condensed water storage tank, condensed water is transported to described condensed water storage tank, and the condensed water in described condensed water storage tank is exported described recovery system by the water pump being attached thereto; By the steam condensate recovery system of above structure is set, separation is also reclaimed condensed water, prevents that the condensed water of high temperature from directly discharging, and prevents that production plant area fog from curling up, and improved plant environment.
As preferably, the number of described water leg is at least 1, and described in each, water leg is communicated with 5-7 and organizes described drain valve; Save described water leg, save space simultaneously.
As preferably, described water pump is variable frequency pump, because described recycling of condensed steam system need to work long hours, utilizes variable frequency pump can save power supply, reduces energy resource consumption.
As preferably, described water pump is two, and one is that one of process pump is stand-by pump, described in be designed to Redundancy Design, can, when a water pump can not be worked, guarantee the normal operation of this system.
As preferably, on described condensed water storage tank outer wall, be provided with liquid level gauge; Described liquid level gauge is for detection of the liquid level of described condensed water, when the liquid level of described condensed water storage tank reaches after liquid level gauge setting height, by opening water pump, discharges.
The beneficial effects of the utility model are: by steam condensate recovery system is set, separation is also reclaimed condensed water, reduces when polluting and reduces the cost of sewage disposal, thereby reach the waste that reduces resource.
Accompanying drawing explanation
Fig. 1 is steam condensate recovery system schematic diagram described in the utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
A kind of steam condensate recovery system as shown in Figure 1, comprise drain valve 1, water leg 2, condensed water storage tank 3 and desalted water pipe network, described drain valve 1 one end is connected with gas utilization unit, the other end is connected with described water leg 2, described water leg 2 is collected steam condensate (SC) and is separated, described water leg 2 is connected with described condensed water storage tank 3, described condensed water is transported to described condensed water storage tank 3, and the condensed water in described condensed water storage tank 3 is transported to described desalination pipe network by the water pump 4 being attached thereto and carries out desalination; By after described steam plant, steam condensate recovery system being set, separation is also reclaimed condensed water, reduces when polluting and reduces the cost of sewage disposal, thereby reach the waste that reduces resource.
Described drain valve 1 is connected with described water leg 2 with described gas utilization unit by pipeline; Utilize pipeline syndeton simple, cost is low.
5-7 organizes described drain valve 1 and shares a described water leg 2; By integrated described drain valve, save described water leg, save space simultaneously.
Described water pump 4 is variable frequency pump, because described recycling of condensed steam system need to work long hours, utilizes variable frequency pump can save power supply, reduces energy resource consumption.
On described condensed water storage tank 3, be provided with liquid level gauge 5, described liquid level gauge is for detection of the liquid level of described condensed water, when the liquid level of described condensed water storage tank 3 reaches after liquid level gauge setting height, by opening water pump 4, discharges.
Described water leg 3 can be selected riding position according to described gas utilization unit and described drain valve 1 position.
Experimental data of the present utility model: the 200000 tons/year of production-scale synthetic ammonia installations of take are example, it needs to consume 58.68 ten thousand tons of desalted waters every year, and nearly 50,000 tons/year of draining by blowdown pipeline and drain valve, according to 10 yuan of calculating of desalted water production cost per ton,, after these water discharges, also there is blowdown governing problem in 500,000 yuan of annual waste production costs simultaneously.After adopting recovery system of the present utility model, can save production cost every year nearly 500,000 yuan, nearly 200,000 yuan of blowdown cost is administered plant environment simultaneously, reduces visual pollution.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
