Description

A kind of Generator Stator Cooling water basification automaton
Technical field
The utility model is mainly used in thermal power plant Generator Stator Cooling water system, and more particularly to a kind of generator is determined Sub- cooling water basification automaton.
Background technology
To ensure the safe operation of thermal power plant generating set, national standard and professional standard all define generator and determined The water quality requirement of cold water, current power plant determines cold water treatment mostly all through too small mixed bed processing method, and this method is transported in generator In row, the electrical conductivity and pH for determining cold water matter are relatively low, change small mixed-bed resin frequently, and given cold water storage cistern moisturizing is needed daily, water is changed, Efficiency-cost ratio is low, and currently on the market determine the micro- basification device of cold water, be also that the method for cold water of determining is handled using mixed-bed resin, By processing, determining cold water matter can also reach that standard will be gone, but there is the problem of irregularly changing resin, and operation operation is also compared It is more complicated, in order to solve these problems, it is necessary to which a kind of operation is simple, automation is high determines cold water basification device and method.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model is provided at a kind of Generator Stator Cooling scale Manage automaton, it is possible to achieve Generator Stator Cooling scale is precisely controlled and recycling of economizing on water.
To reach above target, the utility model uses following scheme:
A kind of Generator Stator Cooling water basification automaton, including it is arranged on the U-shaped liquid determined on cold water storage cistern Level control pipe road 7, the return water tank 8 connected with U-shaped Liquid level pipeline 7 is connected on U-shaped Liquid level pipeline 7 and determines fixed The conductivity transmitter 1 of cold water electrical conductivity, with determining the molten medicine-chest 5 of ammonia that cold water storage cistern is connected, is arranged on the molten medicine-chest 5 of ammonia and determines cold water storage cistern Frequency conversion peristaltic pump 6 on connecting line, is connected to the liquid level sensor 4 that liquid level is monitored on the molten medicine-chest 5 of ammonia, is arranged on and determines cold water storage cistern Demineralized water refill flow meter 9 on demineralized water water pipe, with conductivity transmitter 1, liquid level sensor 4, frequency conversion peristaltic pump 6 and The PLC2 that demineralized water refill flow meter 9 is connected, the man-machine interface 3 being connected with PLC2.
The conductivity sensor 1 that cold water electrical conductivity is determined in detection on the U-shaped Liquid level pipeline 7 for determine cold water storage cistern is arranged on, will Electrical conductivity SC signals feed back to PLC 2, then the control parameter and working curve for determining cold water are set by man-machine interface 3, and input is extremely PLC 2 automatically controls working frequency and the start and stop of the frequency conversion peristaltic pump 6 for being connected to the molten medicine-chest 5 of ammonia, realizes to determining cold water storage cistern essence Quasi- Automatic Dosing, regulation determines the electrical conductivity and pH of cold water in standard claimed range, and PLC 2 is gathered and filled into desalination to determining cold water storage cistern The flow signal of flowmeter 9, the liquid level signal of the liquid level sensor 4 of the molten medicine-chest of ammonia of water, are output to man-machine interface 3, carry out flow With the monitoring of liquid level, determine the pH value of cold water, logical PLC 2 calculating, which is output in man-machine interface 3, to be shown, the rate of water make-up of demineralized water with The spillway discharge for determining the U-shaped Liquid level pipeline 7 of cold water storage cistern connection reaches balance, while cold water is determined in the control of U-shaped Liquid level pipeline 7 Case passes through the recycling of return water tank 8 in certain liquid level, overflow water.
The control method of Generator Stator Cooling water basification automaton, conductivity sensor 1 detects fixed Sub- cooling water conductivity value SC, and conductivity value SC is fed back into PLC2, pass through formula pH=8.57+ in pure water Ammonia adding System LgSC calculates pH value automatically, because stator cooling water pH is in the range of 8~9, and measuring electrode is added by air, temperature during measurement The influence of the factor of itself, is not easy to automatically control, and the relation of pH value and conductance, and electronic rate is influenceed small by extraneous factor, is held Easily measurement, electrode durable stable inputs the working frequency song for setting conductivity parameters and frequency conversion peristaltic pump by man-machine interface 3 Line etc., it becomes possible to the which automatically and accurately chemical feeding quantity of cold water storage cistern ammonia solution is determined in control, realizes Generator Stator Cooling water basification Automatic accurate control.
Compared to the prior art compared with the utility model possesses following advantage:
The utility model device and method is simple and practical, automate, cost is low, control accuracy is high, can be quickly and accurately The water quality of cold water is determined in regulation, meets the requirement of the control of different Stator quality of cooling water pH and electrical conductivity, can basis The control parameter that the requirement setting of oneself needs, is handled, not blowdown is automatically controlled, simple to operate, fortune without using the small mixed bed of resin Row maintenance cost is low.
Brief description of the drawings
Fig. 1 is the utility model schematic device.
Embodiment
Embodiment of the present utility model is further described below in conjunction with the accompanying drawings:
As shown in figure 1, demineralized water water pipe installs desalination water ga(u)ge 9 additional on cold water storage cistern is determined, cold water storage cistern can determined Install U-shaped Liquid level pipeline 7 on former discharge pipe line additional, and connect recovery tank 8, the molten connection frequency conversion of medicine-chest 5 peristaltic pump 6 of increase ammonia is managed Road, which is attached to, determines cold water storage cistern, and the control frequency conversions of PLC 2 peristaltic pump 6 conveys ammonia solution and determines cold water matter alkali to the amount of cold water storage cistern is determined to realize Change the automatic accurate control of processing, PLC 2 inputs the molten signal of decoction level sensor 4, the signal of desalination water ga(u)ge 9, on man-machine boundary Show that molten medicine-chest liquid level, demineralized water refill flow, pH value are monitored on face 3.
