Description

Continuous blowdown system of boiler recycling system
Technical field
This utility model relates to a kind of continuous blowdown system of boiler recycling system, belongs to effluent from boiler recovery and utilization technology field.
Background technology
Current domestic most power plant continuous blow down system is made up of continuous blowdown flash tank, regular unloading container and related valve, pipeline etc..Boiler-steam dome sewer is discharged into regular unloading container after continuous blowdown flash tank reclaims again, and directly working medium is emitted by regular unloading container, causes unit part working medium and the loss of heat.
Utility model content
For solving the technical problem that prior art exists, this utility model provides a kind of simple in construction, easy to use, makes full use of boiler blowdown water waste heat and carries out heat supply, the continuous blowdown system of boiler recycling system of the effectively save energy.
For achieving the above object, the technical scheme that this utility model is used is continuous blowdown system of boiler recycling system, including: boiler blow-off pipeline, described boiler blow-off pipeline is connected with continuous blowdown flash tank, it is provided with branch road on described boiler blow-off pipeline, described branch road is connected with heat supply pipeline, the first stop valve, steam converter valve and the second stop valve it is disposed with on branch road, being provided with settling tank between described steam converter valve and the second stop valve, the rear end of described steam converter valve is additionally provided with thermometer and Pressure gauge.
Preferably, described settling tank is mainly made up of mud chamber and diversion chamber, and described mud chamber is connected with diversion chamber, and between be provided with dividing plate, it is provided with kuppe in described diversion chamber, water inlet pipe extends in kuppe, and bottom surface, mud chamber is incline structure, and bottom is provided with blow-off pipe, it is provided with drainage screen in the middle part of described mud chamber, top, mud chamber is provided with exhaustor, and top, mud chamber is provided with outlet pipe, and described exhaustor is provided with exhaustor.
Compared with prior art, this utility model has following technical effect that this utility model simple in construction, easy to use, use and boiler blowdown water is connected with heat supply pipeline after pressure and temperature reducing, precipitation process, carrying out power plant's heat supply, make full use of effective energy, one-time investment cost is relatively low, can use reliably and with long-term, the sewer substantially solving boiler generation directly discharges the heat economy loss caused;Can partly improve the thermal efficiency of full factory, reduce unit coal consumption, the steam consumption comprehensive utilization ratio of Shi Quan factory obtains and improves to a certain extent, can be effectively accomplished the effect of energy efficiency, can reach good social benefit, also can improve the competitiveness of enterprise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of settling tank in this utility model.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1, continuous blowdown system of boiler recycling system, including: boiler blow-off pipeline 1, boiler blow-off pipeline 1 is connected with continuous blowdown flash tank 2, being provided with branch road 3 on boiler blow-off pipeline 1, branch road 3 is connected with heat supply pipeline 4, and branch road 3 is disposed with the first stop valve 5, steam converter valve 6 and the second stop valve 7, being provided with settling tank 8 between steam converter valve 6 and the second stop valve 7, the rear end of steam converter valve 6 is additionally provided with thermometer 9 and Pressure gauge 10.
Continuous blowdown system of boiler water is delivered to boiler blow-off pipeline, a part to continuous blowdown flash tank carries out dilatation, another part is connected with heat supply pipeline through branch road, after sequentially passing through pressure and temperature reducing, precipitation process, flowing into heat supply pipeline, participate in heat supply, one-time investment cost is relatively low, can use reliably and with long-term, the sewer substantially solving boiler generation directly discharges the heat economy loss caused;Can partly improve the thermal efficiency of full factory, reduce unit coal consumption, the steam consumption comprehensive utilization ratio of Shi Quan factory obtains and improves to a certain extent, can be effectively accomplished the effect of energy efficiency, can reach good social benefit, also can improve the competitiveness of enterprise.
Wherein, as in figure 2 it is shown, settling tank 8 is mainly made up of mud chamber 11 and diversion chamber 12, mud chamber 11 is connected with diversion chamber 12, being provided with dividing plate 13 between and, be provided with kuppe 14 in diversion chamber 12, water inlet pipe 15 extends in kuppe 14, bottom surface, mud chamber 11 is incline structure, and bottom is provided with blow-off pipe 20, being provided with drainage screen 16 in the middle part of mud chamber 11, top, mud chamber 11 is provided with exhaustor 17, top, mud chamber 11 is provided with outlet pipe 18, and exhaustor 17 is provided with exhaustor 19.
Boiler blowdown water enters settling tank through water inlet pipe, current stabilization is carried out by kuppe, then precipitated by ground, mud chamber swash plate, impurity in precipitation sewage, after being then passed through strainer filtering, entering heat supply pipeline by outlet pipe, wherein exhaustor is for emptying the air in mud chamber, prevents from affecting heat supply pipeline heat supply.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, in the range of all should wrapping in this utility model.
