专利汇可以提供Condensed water dechlorination apparatus专利检索，专利查询，专利分析的服务。并且In a condensed water dechlorination apparatus for a thermal power plant or a nuclear power plant, air is trapped into a dechlorination tower during resin regeneration in the tower, so that boiler corrosion may possibly be enhanced when blow water is directly used. Therefore, a system is additionally provided for introducing the blow water into the steam condenser for the purpose of removing oxygen dissolved in the water.，下面是Condensed water dechlorination apparatus专利的具体信息内容。
1. Condensed water dechlorination apparatus comprising: a steam condenser maintained at a negative pressure; boiler means for producing steam; first conduit means for passing water produced in said condenser to said boiler means; means for returning steam produced in said boiler means to said steam condenser; a water supply tank for supplying make up water to said steam condenser; a second conduit means fluidly connecting said supply tank to said steam condenser; a pump in said second conduit means for pumping water from said supply tank to said steam condenser; a control valve attached to said second conduit means for controlling the flow of water from said supply tank to said steam condenser; at least one dechlorination water tower including a quantity of resin which must be periodically withdrawn, regenerated and reinserted into said dechlorination tower to remain effective, said dechlorination tower being attached to said first conduit means intermediate said steam condenser and said boiler; a blow pipe fluidly connected to the downstream side of said dechlorination water tower and in fluid communication with said second conduit upstream of said pump and control valve for passing blow water produced in said dechlorination water tower immediately after regeneration and replacement of said resin therein to said second conduit; and valve means fluidly connected to said dechlorination water tower for causing the water passing out of said dechlorination water tower to pass through said first conduit means and into said boiler during normal operation of said apparatus and for further causing the water passing out of said dechlorination water tower to pass through said blow pipe immediately after the regenerated resin is reinserted into said dechlorination water tower.
2. The condensed water dechlorination apparatus of claim 1, wherein said condenser is provided with a nozzle means for spraying blow water returning through said supply pipe into said condenser.
3. The condensed water dechlorination apparatus of claim 1, wherein a resin strainer is provided in said blow pipe.
4. The condensed water dechlorination apparatus of claim 1, wherein said blow pipe is fluidly connected to said water supply tank.
5. The condensed water dechlorination apparatus of claim 1, further comprising a pump attached to said first conduit downstream of said dechlorination water tower.
6. The condensed water dechlorination apparatus of claim 1, further comprising a resin strainer in said first conduit downstream of said dechlorination water tower.
7. The condensed water dechlorination apparatus of claim 1, including a plurality of dechlorination water towers connected in parallel to said first conduit.
8. The condensed water dechlorination apparatus of claim 1, including three dechlorination water towers.
9. The condensed water dechlorination apparatus of claim 1, wherein said blow pipe is attached to said first conduit downstream of said dechlorination water tower.
10. The condensed water dechlorination apparatus of claim 9, wherein said valve means includes a first valve attached to said blow pipe and a second valve attached to said first conduit downstream of the point where said blow pipe is attached to said conduit.
11. In a condensed water dechlorination apparatus including at least one dechlorination water tower having a resin therein which must be periodically regenerated, means for passing condensed water from a steam condenser to a boiler attached to said dechlorination water tower, a blow pipe for dischArging water out of said dechlorination tower and a make up water storage tank connected via a conduit means to said steam condenser; means for recirculating the flow water produced upon regeneration of said resin without interrupting the operation of said steam condenser comprising means fluidly connecting said blow pipe with said steam condenser, and control means in said connecting means for controlling the flow of fluids therethrough.
12. The condensed water dechlorination apparatus according to claim 11, further including pump means attached to said connecting means.
13. The condensed water dechlorination apparatus of claim 11, wherein said connecting means is fluidly connected with said water supply tank.
14. A condensed water dechlorination apparatus comprising: a steam condenser; at least one dechlorination water tower which periodically produces blow water attached to said steam condenser; connecting means fluidly connecting the outlet of said at least one dechlorination water tower with said steam condenser so that blow water produced in said dechlorination water tower can be recycled to said steam condenser; and control means for controlling the flow of fluid through said connecting means, said control means allowing blow water to flow from said dechlorination water tower to said steam condenser but preventing the breakdown of the vacuum in said steam condenser.
15. The condensed water dechlorination tower of claim 14, wherein said control means includes pump means attached to said connecting means.
16. The condensed water dechlorination apparatus of claim 14, wherein said control means includes a water supply tank connected to said connecting means.
17. The condensed water dechlorination apparatus of claim 14, further including a boiler and second connecting means connecting the outlet of said at least one dechlorination tower with said boiler.
18. The condensed water dechlorination apparatus of claim 17, further including valve means in fluid communication with the outlet of said at least one dechlorination water tower for alternately passing the water passing out of said dechlorination tower to said connecting means and said second connecting means.
