Description
Technical field
The utility model relates to thermal power generation boiler of power plant carbonated drink chemical supervision field, particularly a kind of thermal power generation unit sampling cooling water recycling device.
Background technique
In recent years, along with industrial, agriculture development, also increasing to the consumption of the water yield, along with the continuous exploitation at water source, people are also more and more urgent to reusing of water source.Sustainable utilization of water resource is carried out the principle of continuous utilization for guaranteeing human society, economy and living environment sustainable development to water resources.
In order to guarantee the Steam-water Quality of heat power plant boiler, prevent that the bad phenomenon such as boiler and steam turbine salification, fouling, corrosion from occurring, during boiler operatiopn, to carry out chemical supervision to the feedwater of boiler, stove water, steam and steam turbine water of condensation, hydrophobic etc., check whether Steam-water Quality meets the requirements.
For systematic sampling apparatus function, require: sampler has the automatism isolation protective measure of sample water overtemperature, superpressure, condensate water cutoff.Independently protective gear and superpressure discharge viscous liquid flow voltage-stabilizing device are set; can realize the control of automatically releasing to sample water; device can cut off the overtemperature sample water that enters chemical on-line analysis instrument automatically, and discharges unnecessary sample water by superpressure tapping equipment, and instrument and valve are protected.Sample water pressure can be constant, constant scope 0～0.4MPa, and wave range ± 0.05MPa, thereby to prevent that the fluctuation of instrument sample water flow from affecting accuracy of instrument.
For system layout, require: every unit is equipped with the steam that 1 cover is complete and concentrates sampling analysis device, comprises probe tube and stand for sample tube, water-cooling tube, waste pipe, valve and cable etc. within the scope of High Temperature High Pressure frame, instrumental analysis screen, constant temperature device, manual sampling groove and device.
For sampling water quantity and the water yield, require: the subcritical pulverized coal fired boiler of the 300MW of take is example, and sample point mainly contains: condensed water sampling, oxygen-eliminating device outlet sampling, the sampling of economizer entrance, drum boiler water sampling, saturated vapour sampling, superheated vapor sampling, reheated steam outlet sampling, HP heater drainage sampling, low plus hydrophobic sampling, enclosed water sampling, the hydrophobic sampling of heating device, generator stator cooling water sampling.With each water sample 500～700ml/min, calculate, within one hour, the water yield is: 360L～504L, within one day, sampling water is: 8.64m
3/ d～12.096m
3/ d.
Due to device, configuration and sampling water quantity and the water yield particular requirement of system, therefore, how effectively thermal power generation unit sampling cooling water to be recycled and to become related domain technical problem urgently to be resolved hurrily.
Model utility content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of thermal power generation unit sampling cooling water recycling device is provided, the effectively using water wisely of this recycle device, for making full use of of related domain water resources provides a kind of effective means.
The purpose of this utility model is to solve by the following technical programs the problems referred to above:
A kind of thermal power generation unit sampling cooling water recycling device, comprise several systematic sampling mouths, described several systematic sampling mouths are connected to return water tank by pipeline respectively, return water tank is leaded up to pipeline connection valve to gutter, and the pipeline of separately leading up to connects recovered water pump respectively to circulating water pool and unboiled water pond.
Preferably, the recovered water pump that described pipeline connects is provided with two.
Preferably, described return water tank is provided with level meter.
Preferably, between described recovered water pump and circulating water pool and unboiled water pond, be provided with pressure gauge.
With respect to prior art, feature of the present utility model is:
1), by newly increase a water tank, two water pumps on systematic sampling mouth, sampling water reclaimer operation is convenient.
2) effectively using water wisely after native system transformation, calculates by the normal operation of annual unit for 300 days, can using water wisely 2592m
3～3628.8m
3.
3) using water wisely effectively after the system reform, fully should be used as good demonstration to water resources.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, does not form to improper restriction of the present utility model, in the accompanying drawings:

Wherein: 1, systematic sampling mouth; 2, return water tank; 3, recovered water pump; 4, gutter; 5, circulating water pool; 6, unboiled water pond.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe the utility model in detail, in this illustrative examples of the present utility model and explanation, be used for explaining the utility model, but not as to restriction of the present utility model.
As shown in Figure 1, this thermal power generation unit sampling cooling water recycling device, comprise several systematic sampling mouths 1, described several systematic sampling mouths 1 are connected to return water tank 2 by pipeline respectively, return water tank 2 is leaded up to pipeline and is connected valve to gutter 4, and the pipeline of separately leading up to connects recovered water pump 3 respectively to circulating water pool 5 and unboiled water pond 6.The recovered water pump 3 that described pipeline connects is provided with two.Described return water tank 2 is provided with level meter.Between recovered water pump 3 and circulating water pool 5 and unboiled water pond 6, be provided with pressure gauge.
The circuit design of the utility model sampling water recycling:
A water storage box is set, the water of sampling rhone is pooled to water storage box, then establish two of positions water pump sampling water is recycled.Concrete increase equipment is as follows:
1. it is 1m that volume is set
3sample water stainless steel return water tank.
2. two flow 1m
3/ h, the reuse water pump of lift 1.0MPa.
3. with supporting level meter, valve and the pipeline of water storage box.
Concrete operation step:
1 initial start stage, when water sample is mixed, opens return water tank blowdown valve, and sampling water is by return water tank blowdown valve and overflow to drainage channel, then flow to wastewater disposal basin.
2 sampling water water quality are closed return water tank blowdown valve after taking a turn for the better, and open recovered water pump terminal valve, open return water pipe to circulating water pool valve, close return water pipe to raw water tank valve.After cistern water level to be recycled reach a certain height, start recycle-water pump recovered water pump water in return water tank and be transported to circulating water pool as circulating water system.
After 3 sampling water water quality are all qualified, open recovery tube to raw water tank valve, close recovery tube to circulating water pool valve, by recovered water pump, sampling water is recycled to unboiled water pond.
