Description
Technical field
The utility model relates to combustion and steam combined-cycle power plant technical field, relates in particular to a kind of condensed water thermal deaerator.
Background technology
The combustion and steam combined cycle generation is fast-developing in the world with unimpeachable advantage owing to having accomplished that thereby the cascade utilization of energy has obtained higher energy utilization rate.The annual newly-increased combined cycle generation total installation of generating capacity of developed country accounts for 40%～50% of the newly-increased capacity of thermoelectricity at present; China has also obtained swift and violent development in the combined cycle generation field in recent years; Deoxygenator is as the visual plant in the power generation system, and new deoxygenation technology has also obtained widespread use.Up to the beginning of this century, what the deoxygenator of China's power sector still mainly adopted is that the hair style deoxygenator is arranged, and is made up of deoxygenation head and water tank.On the one hand, because the deoxygenation head is set on the water tank, therefore this deoxygenator height is higher, correspondingly need increase factory building height, increases cost of investment.On the other hand, this have the maintenance cost of hair style deoxygenator also bigger, and therefore, the built-in deoxygenator technology of deoxygenation simple in structure has obtained development fast.Chinese patent 2641473 discloses the built-in thermal deaerator of a kind of low level without a head; It comprises a horizontal deoxygenation water tank; Its top is provided with and comprises main team pipe, soft water import, balance of steam pipe and vent valve; Deoxygenation water tank internal upper part is provided with air feeding tube, and said air feeding tube is connected with said main team pipe; On said air feeding tube, establish the hole and connect branch water arm, which is provided with water outlet; Establish the hole in the bottom of this deoxygenation water tank and connect deaerated water discharge mouth-piece; Said soft water import is communicated with said air feeding tube through a spraying gun; Said main team pipe, the soft water import setting of on the length direction of said water tank, staggering, one of which is arranged at the centre of water tank, and another then is arranged on the two ends of water tank.Its water outlet place is provided with supercharging device and Device for preventing rotation.Deoxygenation head above the above-mentioned deoxygenator cancellation deoxygenation water tank also can be eliminated the restriction of deoxygenator mounting height, but complex structure.
Summary of the invention
The purpose of the utility model provides a kind of height built-in bubble-cap formula thermal deaerator lower, simple in structure.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of built-in bubble-cap formula deoxygenator is characterized in that: have the deoxygenator body, deoxygenator body one end top is provided with into water adapter, is provided with rising pipe in the other end bottom; In the water inlet pipe set inside atomizing nozzle is arranged, be provided with collection oxygen cover in the deoxygenator body outside atomizing nozzle, offer oxygen discharging tube on the deoxygenator body in collection oxygen cover; End near atomizing nozzle in the deoxygenator body is vertically installed with traverse baffle, is vertically installed with steam baffle at the other end near rising pipe, is provided with some groups of steam inlet pipes in deoxygenator body bottom, and the steam inlet pipe top is provided with bubble plate.
As preferably, the upper limb of traverse baffle is higher than the normal water bit line of deoxygenator, and passage is left in the lower rim of traverse baffle and deoxygenator bottom.
As preferably, bubble plate is provided with profile of tooth below (6).
As preferably, certain interval is left in steam baffle (8) lower rim and deoxygenator bottom.
The beneficial effect of the utility model is: this deoxygenator is with respect to conventional built-in deaerator, replaced heating steam bubbling pipe group because of adopting the bubble plate structure, have simple and reliable for structure, characteristics such as the water outlet oxygen level is little, and the steam discharge loss is little, and operation and maintenance cost is low; Be particularly useful for the condensed water deoxygenation in the combustion and steam turbine association circulating power generation system.
