Description
Technical field
The utility model belongs to thermal power generating technology field, relates to unloading acid system in thermal electric generation, especially relates to a kind of circulating water and unloads acid buffering tank.
Background technology
Company 4 × 600MW coal unit, for preventing condenser corrosion and scaling in operation, carrys out auxiliary adjustment circulating water PH value by adding sulfuric acid, sulfuric acid dosage monthly about 120 tons, according to not having the calculating of 35 tons, car sulfuric acid, monthly needs to unload sulfuric acid 4 car.Circulating water unloads sulfuric acid operating process: tank car arrives and unloads sulfuric acid pump place, with flexible pipe by tank car with unload sulfuric acid pump and be connected, then startup unloads sulfuric acid pump, by sulfuric acid suction sulphuric acid tank.Sour mode of unloading like this mainly contains following a few point defect:
1, flexible pipe with unload sulfuric acid pump place and be connected unreliable, unload acid at every turn and all have a small amount of sulfuric acid and spill, corrosion can be caused to the basis of ground, raceway groove and Adjacent Buildings, threaten the safety of building;
2, due to connect tank car and the pipeline unloading sulfuric acid pump wherein one section be pvc pipe, and sulfuric acid proportion is larger, when sulfuric acid pump is unloaded in each startup, the PVC pipeline connected swings larger, once pvc pipe is thrown off, sulfuric acid sprays from pipeline, will cause great injury, and therefore there is larger potential safety hazard to unloading sour operating personal;
3, after unsnatching sulfuric acid, when removing connecting hose, all the time portion of residual sulfuric acid is had can not to be drained only completely in pipeline, after per car acid is unsnatched, about about the 60kg of ducted remaining sulfuric acid, directly pours in cooling tower after the tipping of needs bucket, this also brings great potential safety hazard to operating personal, if directly the remaining sulfuric acid in pipeline is disposed to trench, trench and the corrosion of Adjacent Buildings basis will be caused on the one hand, will the significant wastage of sulfuric acid be caused on the other hand.
Utility model content
In order to solve the problem, the utility model provides a kind of circulating water and unloads acid buffering tank, thus reach avoid acid leak, safety unload acid effect.
The utility model is achieved by following technical solution.
A kind of circulating water unloads acid buffering tank, and comprise buffering tank body and unload sour pump, described buffering tank body upper end is provided with acid inlet valve and evacuated tube, lower end is provided with unloads sour valve, buffering tank body is provided with liquidometer, described in unload sour pump input end and unload sour valve and be communicated with, mouth is provided with and unloads sour pump valve.
Described buffering tank body is pressure-bearing type; Described buffering tank body lower end is also provided with foul valve; Described acid inlet valve inflow point is connected with acid inlet tube; Described acid inlet tube is carbon steel rubber-lined pipe; Described evacuated tube highest point is higher than the sulphuric acid tank top at buffering tank body place.
The beneficial effects of the utility model are:
A kind of circulating water described in the utility model unloads acid buffering tank, by arranging buffer tank structure, and establishes evacuated tube on buffering tank body, sulfuric acid solution is made to flow into buffering tank body smoothly, pump in sulphuric acid tank after sulfuric acid tank body buffering, reach pressure buffer effect, effectively avoid unloading sour pipe vibration; Meanwhile, acid inlet tube one end is directly kept being connected with acid inlet valve, decreases dismounting pipeline link, and adopt carbon steel rubber-lined pipe as acid inlet tube, ensure that pipeline connects reliable, and not easily damaged; After unloading sour end-of-job, the remaining sulfuric acid in pipeline can emptying be temporarily stored in expansion tank, ensures that operating personal is away from sulfuric acid, to stop potential safety hazard.
Whole buffer tank structure has stopped to unload sulfuric acid leakage in sour process, solves sulfuric acid and discharges the personal safety of threat operating personal, contaminated environment, etching apparatus, to the basic problem bringing potential safety hazard of Adjacent Buildings, also mitigates hand labor intensity simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-cushions tank body, 2-evacuated tube, 3-acid inlet valve, 4-foul valve, and 5-unloads sour valve, and 6-unloads sour pump, and 7-unloads sour pump valve, 8-liquidometer, 9-acid inlet tube, 10-circulating water sulphuric acid tank.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, a kind of circulating water described in the utility model unloads acid buffering tank, and comprise buffering tank body 1 and unload sour pump 6, described buffering tank body 1 is pressure-bearing type, and upper end is provided with acid inlet valve 3 and evacuated tube 2, and lower end is provided with unloads sour valve 5 and foul valve 4; Described acid inlet valve 3 inflow point is connected with acid inlet tube 9, and acid inlet tube 9 is carbon steel rubber-lined pipe; Described evacuated tube 2 highest point is higher than the sulphuric acid tank top at buffering tank body 1 place; Buffering tank body 1 is provided with liquidometer 8, described in unload sour pump 6 input end and unload sour valve 5 and be communicated with, mouth is provided with and unloads sour pump valve 7.
Embodiment
To unload acid buffering tank is arranged on circulating water sulphuric acid tank 10, and its installation site lower than circulating water sulphuric acid tank 10, and joins liquidometer 8 to capacity at the buffering tank body 1 of more than 300L, being communicated with, completing installation by unloading the sour valve 5 that unloads of sour pump 6 with buffering tank body.Before work, acid inlet valve 3, foul valve 4, unload sour valve 5, unload sour pump valve 7 and be all in closed condition, tank car arrives circulating water sulphuric acid tank 10 place, by acid inlet tube 9 and tank car outlet, unload sour pump valve 7 and keep being connected with circulating water sulphuric acid tank 10, open acid inlet valve 3 successively, unload sour valve 5, unload sour pump valve 7, start and unload sour pump 6, according to the increase of the liquidometer 8 on circulating water sulphuric acid tank 10 or the outlet valve aperture of the adjustment tank car that declines, until sulfuric acid flows only completely, keep unloading sour pump 6 and work 30 seconds; Sour pump 6 is unloaded in closedown, closes and unloads sour pump valve 7 and unload sour valve 5; Treat that the remaining liquid in acid inlet tube all flows in expansion tank body 1, close acid inlet valve 3, acid inlet tube 9 is removed from tank car, completes and unload acid.Unloading in sour tank maintaining process, foul valve 4 can be opened, the accretion in buffering tank body 1 and impurity are discharged.
The technical program reduces to unload and to connect before and after acid and to withdraw from the danger of pipeline, simultaneously tank car and unload between sour tank and use gravity flow mode, can not there is the sulfuric acid of pipe interior remnants, No leakage, can not cause corrosion to raceway groove and building etc.
