Description
Technical field
This utility model relates to water chiller field, thermal power plant, particularly relates to a kind of condenser high temperature water charging system and method.
Background technology
At present in wet type cooling unit Condenser Design, condenser water replenishing technology is a critically important ring.Moisturizing temperature under normal circumstances is less than turbine discharge temperature, now, moisturizing is accessed from throat, sprays into condenser, flow in condenser shell with steam flow after atomization, is beneficial to cooling turbine discharge.But, when moisturizing temperature is higher than turbine discharge temperature, if still spraying into condenser from throat, the high-temperature water filled into will heat turbine discharge, and this is disadvantageous to cooling efficiency of condensers.If directly accessing condenser hotwell by pipeline, not only noise is big, also results in liquid level in hot well unstable.When Steam Turbine is properly functioning, liquid level in condenser is monitored in real time, when erratic fluctuation occurs in liquid level, be easily caused monitoring system mistake and be identified as liquid level and abnormal warning occur, consequently, it is possible to produce the error protection to whole generating set.Present stage, this high temperature moisturizing situation was the most universal in UTILIZATION OF VESIDUAL HEAT IN power plant.From now on, along with thermal power generation is saved energy and reduce the cost the going deep into of work, conventional thermal power plant also will run into this type high temp moisturizing situation.How can effectively carry out high temperature moisturizing accessing condenser is the most required problem solved.
Utility model content
The purpose of this utility model is to provide a kind of Appropriate application power plant cold end (recirculated water/exhaust steam) waste heat, improves efficiency of energy utilization, it is achieved high temperature moisturizing accesses the system and method for condenser.
To achieve these goals, the technical solution of the utility model is: a kind of condenser high temperature water charging system, including condenser, high temperature water replanishing device；It is characterized in that, high temperature water replanishing device is made up of filling pipe, connecting tube and spraying mechanism, and spraying mechanism is arranged in condenser hotwell, is positioned at hot well ullage, is connected with filling pipe by connecting tube.
Further, filling pipe accesses from condenser throat or hot well.
Further, filling pipe is when throat accesses, and connecting tube is disposed to extend to hot well from condenser shell sidewall, keeps certain distance away from condenser shell sidewall, and distance selects 50-100mm.
Further, connecting tube is made up of straight-run of pipe, or is connected and composed by multistage straight tube.
Further, spraying mechanism is arranged in parallel in hot well, keeps certain distance with liquid level.
Further, spraying mechanism can be by a water pipe square plate in the horizontal plane around being formed, it is possible to uses many group water pipe compositions arranged in parallel.
Further, below the water pipe of spraying mechanism, the position towards hot well water direction has multiple hole for water spraying.
This utility model uses and high temperature moisturizing accesses the injection of hot well atomized spray, it is achieved that condenser high temperature moisturizing, had both achieved the reasonable method for supplementing water of high-temperature water, and had also been measures to effectively increase energy savings and reduce material consumption.

Detailed description of the invention
1 pair of this utility model is further described below in conjunction with the accompanying drawings, it will be appreciated that content described herein is merely to illustrate and explains this utility model, is not used to limit this utility model.
Such as the condenser high temperature water replanishing device structural representation in Fig. 1, condenser high temperature water replanishing device includes filling pipe, connecting tube and spraying mechanism, filling pipe is connected to coagulator throat or hot well, filling pipe is attached by connecting tube with spraying mechanism, spraying mechanism is positioned horizontally in condenser hotwell, and in hot well, ullage keeps certain distance.Spraying mechanism can be coiled in horizontal plane by a water pipe and be formed, it is possible to use many group water pipe compositions arranged in parallel.The position punching (towards hot well water direction) below the water pipe of spraying mechanism, depending on the quantity of perforate is according to the size of amount of makeup water.When filling pipe accesses from throat, be around to hot well position in housing.Filling pipe accesses from throat, it is disposed to extend to hot well by connecting tube, certain distance is kept away from Steam Side of Condenser inwall, connecting tube is that substantially vertical mode is arranged, can be made up of straight-run of pipe, it is possible to connected and composed by multistage straight tube, its arrangement keeps certain distance away from condenser inwall, optional 50-100mm, will not produce impact to other structures of condenser inside and interfere.It addition, filling pipe also can be directly accessed (not shown) at hot well, avoid installing at the stringing within condenser.
By filling pipe, high temperature moisturizing is accessed from condenser throat or hot well, pipeline is disposed to extend always about 300mm above hot well normal level, one or a few pipe is arranged in hot well upper horizontal, the thereunder position punching (towards hot well water direction), high temperature moisturizing is sprayed from aperture, is sprayed onto on hot well liquid level.So, when high-temperature water fills into condenser, do not interfere with the turbine discharge steam flow at condenser throat, do not interfere with condenser normal cooling；Spray high temperature moisturizing being realized multiple spot close to hot well ullage, almost without noise, be also not result in that hot well liquid level is unstable.It addition, the high-temperature water filled into can heat hot well water, reduce condenser supercooling degree, thus reduce solidifying water heat regenerative system heating steam consumption.This method for supplementing water, is the reasonable method for supplementing water for high-temperature water, is also measures to effectively increase energy savings and reduce material consumption.The most thoroughly solve the Utilizing question of high temperature moisturizing, and power plant's treatment in accordance with local conditions is made full use of surrounding resources and provides good solution.
Last it is noted that the foregoing is only explanation of the present utility model, it is not limited to this utility model, although this utility model has been described in detail, for a person skilled in the art, aforementioned described technical scheme still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
