Abstract
The utility model relates to a condenser water level automatic control device, which comprises a level transmitter disposed on the side wall of a condenser well. An output end of the level transmitter is connected with an input end of a distributed control system (DCS), and an output end of the distributed control system (DCS) is connected with control ends of a level adjusting electric valve and a water volume adjusting electric valve. The condenser water level automatic control device can timely adjust water level, guarantee stability of over cooling degree, and increase economical benefits of boilers.
Description
Technical field
The utility model relates to a kind of liquid automatic control device, particularly a kind of condenser water level automatic control device.
Background technology
Thermal power generation is that high steam pushing turbine drive generator is finished, and the steam after the acting becomes condensate water by condenser heat exchange cooling, and condensate water is sent into oxygen-eliminating device by condensate pump.In running, generally regulate condenser well water level by the aperture of regulating recirculation (egr) valve.This condenser well water level is at a floor platform, and the control room is at second floor.In the Turbo-generator Set running, when unit load changed, steam consumption changed, and condensing capacity also changes thereupon, water level can rise or descend, and the steam turbine operator on duty need remove to regulate water level to a floor platform by regulating recirculation (egr) valve by the second floor night shift room.Even load is not when changing, also can change with the change water level of the amount of drawing gas.If patrol and examine untimelyly, the condenser full water causes shutdown in the time of can causing vacuum sharply to descend to influence unit load serious; Condensate water is crossed that I haven't seen you for ages and is damaged condensate pump.Steam turbine condenser end is poor, generally is controlled at 8～12 ℃.The condenser water level was regulated to hang down and may be burnt out the condensate pump motor; the condenser water level is regulated too high meeting floods the condenser cooling tube; make the copper pipe fouling easily; supercooling degree (the supercooling degree is the poor of delivery temperature and condensing water temperature) also can be low excessively; the undesired vacuum that influences condenser of work of while air ejector; thereby the load that influences steam turbine reduces, and causes when serious shutting down.Manual adjustment condenser water level exists and regulates shortcomings such as untimely well SEA LEVEL VARIATION is big.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of condenser water level automatic control device is provided, the automaton that this apparatus structure is simple, easy to use, observation is timely, can in time regulate water level.
The technical solution adopted in the utility model is:
A kind of condenser water level automatic control device, comprise the fluid level transmitter that is arranged on the condenser well sidewall, the output of fluid level transmitter links to each other with the input of dcs (DCS), and the output of dcs (DCS) is regulated electrically operated valve with liquid level and linked to each other with the control end that the water yield is regulated electrically operated valve.
The described water yield is regulated electrically operated valve one end and is linked to each other with the condenser well by condensate pump and pipeline, and the other end is connected with oxygen-eliminating device.
Described liquid level is regulated electrically operated valve one end and is linked to each other with condenser well upper end by pipeline, and the other end communicates with the condensate pump delivery port by pipeline.
Fluid level transmitter is carried signal to dcs (DCS), send a signal to liquid level by dcs (DCS) again and regulate electrically operated valve, regulate electrically operated valve by liquid level and control water level, fluid level transmitter feeds back to dcs (DCS) to the signal that detects again again, thereby keeps the water level of condenser well.Condensate water in the condenser well is transported to oxygen-eliminating device by condensate pump, and the water yield is regulated the flow that electrically operated valve control is input to the water of oxygen-eliminating device.
The utility model can in time be regulated water level, has guaranteed the stability of supercooling degree, has improved the economic benefit of boiler.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein 1, condenser well; 2, fluid level transmitter; 3, dcs (DCS); 4, oxygen-eliminating device; 5, the water yield is regulated electrically operated valve; 6, condensate pump; 7, liquid level is regulated electrically operated valve.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
A kind of condenser water level automatic control device, comprise the fluid level transmitter 2 that is arranged on condenser well 1 wall, the output of fluid level transmitter 2 links to each other with the input of dcs (DCS) 3, and the output of dcs (DCS) 3 is regulated electrically operated valve 7 with liquid level and linked to each other with the control end that the water yield is regulated electrically operated valve 5.
The water yield is regulated electrically operated valve 5 one ends and is linked to each other with condenser well 1 by condensate pump 6 and pipeline, and the other end is connected with oxygen-eliminating device 4.
Liquid level is regulated electrically operated valve 7 one ends and is linked to each other with condenser well 1 upper end by pipeline, and the other end communicates with condensate pump 6 delivery ports by pipeline.
Adopting model is that condenser, the model of N-2000 is that 3151 fluid level transmitter, electrically operated valve are PS.Fluid level transmitter 2 is carried the 4-20mA signal to dcs (DCS) 3, carry the 4-20mA signal to regulate electrically operated valve 7 by dcs (DCS) 3 again to liquid level, regulate electrically operated valve 7 by liquid level and control water level, fluid level transmitter 2 feeds back to dcs (DCS) 3 to the signal that detects again again, thereby keeps the water level of condenser well 1.Condensate water in the condenser well 1 is transported to oxygen-eliminating device 4 by condensate pump 6, and the water yield is regulated the flow that electrically operated valve 5 controls are input to the water of oxygen-eliminating device 4.Dcs (DCS) is a prior art.
