Description
Technical field
The utility model relates to boiler technical field of improvement, is specifically related to a kind of continous way drum water system.
Background technology
Steam water-level is one of most important parameter in boiler and control system thereof, and boiler-steam dome equalizing reservoir is used for supporting the use with dipperstick or differential pressure transmitter detecting steam water-level.But because the aspect such as double-chamber balancing vessel and measurement thereof also exists careless omission, when causing in application, wrong generation, even forms potential safety hazard.
For solving the problem, Granted publication is that CN 203642989 U discloses a kind of boiler water level monitoring device, it is characterized in that: comprise the double-chamber balancing vessel for detecting steam water-level and the detected value of double-chamber balancing vessel is carried out to the bucking-out system of auto-compensation; Described double-chamber balancing vessel comprises condensing room, benchmark cup, overflow chamber and linker; Described bucking-out system, for eliminating due to the deviation that variable density causes level measuring in double-chamber balancing vessel, described bucking-out system comprises pressure compensating system and compensation deals system; Described pressure compensating system obtains pressure signal by being arranged at pressure sensor in the water in drum, and pressure signal is input to compensation deals system by pressure transmitter.
This kind of boiler water level monitoring device can be monitored the height of water level constantly and be controlled the startup of boiler water pump, stop, water is heated to boiling from normal temperature and becomes saturated vapor, this process will absorb a large amount of heat energy, strengthen along with going out quantity of steam, steam water-level becomes low water level gradually by high water level, now bucking-out system goes out to start water pump instruction, water pump starts to inject cold water toward drum, in drum, the boiling water of boiling just becomes warm water immediately, saturated vapor is heated into again by warm water, so this process must cause water pump to start frequently repeatedly, stop, 5-7 starting current doubly can be produced during starting mode of pump, to motor and mechanical shock larger, easy generation mechanical wear, waste energy.
Utility model content
For overcoming deficiency of the prior art, the utility model provides the continous way drum water system of a kind of use safety, energy-conserving and environment-protective.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of continous way drum water system, comprise water pump, pump motor and Drum Level Monitoring System, described Drum Level Monitoring System includes double-chamber balancing vessel, differential pressure transmitter, described transformation transmitter is installed on equalizing reservoir, it is characterized in that: also comprise PID controller and frequency converter, described PID controller is connected with differential pressure transmitter, and described frequency converter is arranged on pump motor for controlling pump motor rotating speed.
Further, Drum Level Monitoring System also includes display, and this display is connected with PID controller, for showing the Detection Information of PID controller.
Further, double-chamber balancing vessel is separated into condensing room and overflow chamber, and solidifying air chamber is communicated with drum by drum fairlead respectively with overflow chamber.
Further, equalizing reservoir and drum fairlead are linked by flange or weld.
Further, malleation compensating pipe, negative pressure compensating pipe, water tumbler, funnel and condensate pipe is provided with in double-chamber balancing vessel.
Further, the acceleration of frequency converter, deceleration time can set arbitrarily.
From above-mentioned to description of the present utility model, compared with prior art, the continous way drum water system that the utility model provides, by PID controller and frequency converter, the rotating speed to pump motor precisely controls, realize continuing in drum, steadily supplying water, reduce the cold and hot temperature difference in drum, improve the steam supply quality of steam, because the Acceleration and deceleration time of frequency converter can set arbitrarily, pump motor starting current is from zero to specified, there is no rush of current, not to mechanical shock, prolonged mechanical life-span, power saving rate more than 30%.
Accompanying drawing explanation
Fig. 1 is the structural representation of continous way drum water system.
Detailed description of the invention
Below by way of detailed description of the invention, the utility model will be further described.
A kind of continous way drum water system, comprises drum body 1, Drum Level Monitoring System 2, PID controller 3, frequency converter 4;
Drum body 1 is provided with water pump and pump motor 11, and this drum body is communicated with Drum Level Monitoring System 2 by extraction catheter 12;
Drum Level Monitoring System 2 includes double-chamber balancing vessel 21, differential pressure transmitter 22 and display 23, this double-chamber balancing vessel 21 is separated into condensing room and overflow chamber, solidifying air chamber is communicated with drum body 1 respectively by drum fairlead 11 respectively with overflow chamber, this equalizing reservoir 21 and drum fairlead 11 are linked by flange or weld, malleation compensating pipe 211 is provided with in double-chamber balancing vessel, negative pressure compensating pipe 212, water tumbler 213, funnel 214 and condensate pipe 215, transformation transmitter 12 is installed on equalizing reservoir 11, display 23 is connected with PID controller, for showing the Detection Information of PID controller,
PID controller 3 is connected with differential pressure transmitter 12;
Frequency converter 4 is arranged at for controlling pump motor rotating speed on pump motor, and acceleration, the deceleration time of frequency converter can set arbitrarily.
With reference to shown in Fig. 1, the workflow of above-mentioned continous way drum water system is as follows:
Poor by the height of water level of double-chamber balancing vessel 21, differential pressure ratio is carried out comparatively by differential pressure transmitter 22, the current signal comparing the differential pressure signal drawn and be transformed into 0-20mA is delivered to PID controller 3, PID controller 3 can according to the height of designated water level, be shown on display 23 intuitively, compare according to height of water level (SV) setting value and (PV) measured value simultaneously, computing exports the analog signal of 4-20mA, frequency converter 3 performs rotating speed according to this analog signal and controls, because the Acceleration and deceleration time of frequency converter 3 can set arbitrarily, the soft start of pump motor can be realized, starting current is from zero to Rated motor, there is no rush of current, not to mechanical shock, the prolonged mechanical life-span, therefore very energy-conservation very environmental protection.
Above are only some detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
