Abstract
The utility model provides an apparatus for steam-taking and feeding water into a steam condenser and oxygen removing for steam turbine industry. The utility model adopts high efficiency planar film type nozzles which are controlled in groups. The nozzles and a water baffle plate are tightly fixed to a water supplementing box in the throat part of a steam condenser via basal plates and shims, and the box is supported on a support bar in the throat part of the steam condenser. The apparatus is a new structure, and compared with the existing industrial steam-taking water-feeding and oxygen-removing devices, the apparatus can cancel the investments of the equipment, such as a special low-voltage oxygen removing device, two or three relay-pumps, a heating steam adjusting valve, a safety valve, a water level gauge and other corresponding pipelines. Simultaneously the investments on workshops for the arranging the equipment and systems can be saved. Systems are simplified, and engineering arrangement is convenient. The residual heat of steam discharged by a steam turbine can be utilized, thus external heating steam required due to the adoption of the low-voltage oxygen removing device can be fully saved, the operating cost of a power plant can be reduced, and economical efficiency is increased.
Description
Technical field
The utility model is to utilize the exhausted spare heat after the steam turbine work done, the make-up water of heating heat supply steam turbine extraction steam for factories in vapour condenser, makes it deoxygenation, is a kind of brand-new deaerating plant, especially is fit to the moisturizing deoxygenation of heat supply steam turbine extraction steam for factories.
Background technique
The heat supply steam turbine extraction steam for factories is not recyclable, causes the loss of thermodynamic system of steam tur working medium, must be to the thermodynamic system of steam tur moisturizing, and this moisturizing must enter thermodynamic system again through after the deoxygenation.At present, special low pressure oxygen-eliminating device deoxygenation is adopted in conventional steam turbine extraction steam for factories moisturizing, and it mainly is made up of deoxygenation head, water tank, relay pump, valve, pipeline etc.Make-up water enters from a deoxygenation top water inlet, the heating steam that comes from the steam turbine intermediate extraction enters in the deoxygenation head from a deoxygenation bottom steam port, the spray of moisturizing in the deoxygenation head is partitioned into the film shape with filler and fully contacts with the steam that the bottom enters, be heated to saturation temperature, reach the deoxygenation purpose.The gas of separating out from water is through ease gas exhaust port, and ease gas cooler or relief opening enter atmosphere at last; Water after the deoxygenation enters water tank, delivers in the heat regenerative system of steam turbine through relay pump.For guaranteeing device security, be provided with safety valve, fluviograph, ease stream drain port, level control valve, heating steam pressure modulating valve.There is following shortcoming in this extraction steam for factories moisturizing oxygen-eliminating device: need set up special-purpose moisturizing oxygen-eliminating device and associate member, equipment investment is big; Also need special factory building space to arrange equipment such as oxygen-eliminating device, valve, relay pump, pipeline during engineering design, it is big to take the factory building space, makes and arranges that difficulty increases; Need special-purpose steam turbine intermediate extraction to heat moisturizing, the operating cost height simultaneously.Known to the research of claimant's professional production: the application's device does not still have the actual achievement of design, manufacturing, application except that the claimant.
The model utility content
The purpose of this utility model is: fill up this blank, a kind of extraction steam for factories moisturizing deaerating plant that utilizes the turbine discharge waste heat to come heat make-up water is provided.
The purpose of this utility model is to realize by following technical solution: plane membrane type nozzle, manger board are fastened on the moisturizing header in the condenser throat by substrate, pad, this header be bearing in the condenser throat strut on.
Plane membrane type nozzle on the described moisturizing header layout that is parallel to each other.
Described moisturizing header links to each other with industrial moisturizing source by the moisturizing intake pipe, is equipped with the jet pressure modulating valve on the moisturizing intake pipe.
Owing to adopt said structure, moisturizing enters header through inlet valve, spray in the condenser throat through the plane membrane type nozzle of arranging that is parallel to each other again, because each plane moisture film is parallel to each other, thereby form several vertical stream passageways, when turbine discharge from up to down flows in passage, directly and the moisture film contact heat-exchanging, constantly the condensation heat by steam heats moisturizing, because current are turbulent shapes, the heat-transfer coefficient height, thus the extraction steam for factories supplementing water is heated to saturation state, realize the deoxygenation of moisturizing.
The beneficial effects of the utility model: compare with existing extraction steam for factories moisturizing deaerating plant, this device can be cancelled the equipment investments such as low pressure oxygen-eliminating device, 2-3 platform relay pump, heating steam modulating valve, safety valve, fluviograph and each corresponding pipeline of a special use; Also can save simultaneously factory building investment for arranging that the said equipment and system increase; Simplified system, it is more convenient that engineering is arranged; Can utilize the turbine discharge waste heat, thereby save external heating steam fully, power plant's operating cost is reduced significantly, improve performance driving economy because of adopting the low pressure oxygen-eliminating device to need.
