Technical field
The utility model is related to a kind of waterworks more particularly to a kind of pulverized-coal fired boiler waterworks.
Background technology
Boiler is power source important in production and life, occupies sizable proportion in entire energy consumption.Wherein, pot
The station service accounting that stove water supply system is consumed is larger, for the feed water system of boiler, due in design selection, generally using half
Theoretical semiempirical mode selects power-equipment -- the boiler feed pump of the feed water system of boiler, in engineering construction completion equipment investment
During operation, will necessarily there are the deviation that boiler feed pump and the feed water system of boiler match, i.e., system and power set (boiler to
Water pump) Incomplete matching.In addition, boiler load, combustion conditions, when changing, the amount of water required and pressure also change therewith.
Efficiency is relatively low in actual operation for the feed water system of boiler, and energy waste is serious.
Utility model content
Against the above deficiency, the purpose of this utility model is to provide a kind of pulverized-coal fired boiler waterworks, can be straight in real time
That sees monitors to enter the pressure and flow of water in boiler, and according to demand of the boiler to hydraulic pressure and water, adjusts feedwater in real time
Pressure and flow, practicability is high, efficient and energy saving.
Used technical solution is the utility model in order to achieve the above objectives：
A kind of pulverized-coal fired boiler waterworks, which is characterized in that including a softened water tank and an oxygen-eliminating device, the softened water tank is with removing
Connected between oxygen device by a soft water supply pipeline, be provided on the soft water supply pipeline it is several except oxygen pump, in the oxygen-eliminating device
Lower end is connected with a feed mechanism, which includes a water main and be set to the port of export of water main
Several groups, to water assembly, should include several subfeeders being in parallel to water assembly, a feedwater is provided on the subfeeder
Pump and respectively be located at feed pump front and back the first regulating valve, and the port of export to water assembly be provided with a pressure gauge with
Flow meters.
As further improvement of the utility model, the soft water supply pipeline includes several soft water supply branch being in parallel
Pipe, it is described except oxygen pump is set on soft water supply branch pipe, and on the soft water supply branch pipe and positioned at except oxygen pump front and back difference
It is provided with one second regulating valve.
As further improvement of the utility model, a liquid level gauge is provided on the softened water tank, and in the softened water tank side
Side top offers an overflow port.
As further improvement of the utility model, the softened water tank is connected to several automatical softeners.
As further improvement of the utility model, the oxygen-eliminating device is thermal deaerator.
The beneficial effects of the utility model are：It can intuitively monitor to enter in boiler in real time by pressure gauge and flowmeter
The pressure and flow of water when undesirable, can be matched with feed pump by regulating valve and adjust feed pressure and stream in real time
Amount, to adapt to demand of the boiler to hydraulic pressure and water, not only increases the practicability of waterworks, and improve waterworks
Efficiency.
Above-mentioned is the general introduction of utility model technical solution, below in conjunction with attached drawing and specific embodiment, to the utility model
It is described further.
Description of the drawings
