The lower-position deaerator water charging system comprises four water charging pumps, two deaerators, two pressure pumps, and two boilers. An outlet pipeline of a first water charging pump and an outlet pipeline of a second water charging pump share a first protopipe. An outlet pipeline of a third water charging pump and an outlet pipeline of a fourth water charging pump share a second protopipe. The first protopipe is connected with a first deaerator. The second protopipe is connected with a second deaerator. Outlet pipelines of the two deaerators share a third protopipe. A first boiler is connected with the third protopipe through a first pressure pump. A second boiler is connected with the third protopipe through a second pressure pump. The low-position deaerator water charging system has the advantages of ensuring efficient operation of the frequency conversion water charging pumps, realizing synchronous stable operation of the two deaerators, meeting the normal requirement of the boilers for water amount, and ensuring normal safe production of on-site users.
Description
Technical field
The utility model belongs to the boiler replenishing water field, specifically a kind of low-level deaerator water charging system.
Background technology
The existing two cover oxygen-eliminating devices in the active operation area of Shanxi Taigang Stainless Steel Co., Ltd's steel pipe for 20 tons of evaporation capacity/time two steam boiler deoxygenations, the oxygen-eliminating device supplementing water is the demineralized water that phreatic water is processed through two cover cationic ion-exchange resins, demineralized water enters on-the-spot softened water tank by softened water pump, by four frequency conversion small pumps, by main water outlet pipe, supply to enter boiler after No. 1, No. 2 oxygen-eliminating device deoxygenations again.In actual motion, because two cover oxygen-eliminating device operating modes are incomplete same, inside liquid level does not wait, and therefore, often occurs that two cover oxygen-eliminating devices occur that liquid level reports to the police by the forced-stopping machine phenomenon in low level in various degree.Existing two oxygen-eliminating device positions are that low level is installed, if by the form of gravity flow, the water after deoxygenation is because pressure can't enter boiler lower than boiler operatiopn pressure, and therefore, boiler occurs cutting off the water supply phenomenon and affects normal operation.Simultaneously, oxygen-eliminating device mainly supplies boiler deoxidizing method No. 1, No. 2, avoids because oxygen is removed the thorough boiler internal generation corrosion that makes.Method of operation the using and the reserved in summer, winter, the yet all operations of two cover oxygen-eliminating devices, do not have standby because two boilers all put into operation.4 small pumps of on-the-spot outfit, supplement soft water to oxygen-eliminating device, and after deoxygenation, boiler of feeding is used.4 small pumps are respectively No. 1, No. 2 and share a frequency conversion, standby each other, share a frequency conversion No. 3, No. 4, standby each other.Can only throw two water pump moisturizings during operation simultaneously, other two standby.Only have when operation water pump fault, by change-over switch, switch and could drop into corresponding stand-by pump.Oxygen-eliminating device is in service will guarantee that liquid level is constant between 1.4-2.5, and temperature will reach 104 ℃ and just can meet the demands, otherwise shuts down with regard to there will be warning.When two oxygen-eliminating devices all move, two frequency conversion small pump moisturizings simultaneously could meet the requirement of liquid level.But, because two oxygen-eliminating device operating modes have difference, liquid level changes at any time in various degree, so frequency conversion moisturizing water pump needs automatically to change at any time rotating speed and adjusts rate of water make-up.Due to shared main water outlet pipe, the water yield of two small pumps interferes with each other, under this operating mode; the liquid level shutdown of reporting to the police lower than setting value occurs, boiler can not normally be moved, and then affect user's normal production; particularly in the winter time, because heating is interrupted, cause the bursting by freezing of field apparatus facility large tracts of land.Simultaneously, because the oxygen-eliminating device operation is undesired, deoxygenation is not thorough, boiler corrosion occurs.
Summary of the invention
Technical problem to be solved in the utility model is: how to guarantee the normal safe operation of oxygen-eliminating device, and small pump is independent of each other, and independent mutually, have again standby simultaneously.
The technical scheme that the utility model adopts is: the low-level deaerator water charging system, comprise four small pumps, two oxygen-eliminating devices, two force (forcing) pumps, two boilers, No. 1 small pump 7 and No. 2 small pump 8 export pipelines share first female pipe, No. 3 small pumps 9 and No. 4 small pump 10 export pipelines share second female pipe, first female pipe connects the first oxygen-eliminating device 5, second female pipe connects the second oxygen-eliminating device 6, two oxygen-eliminating device export pipelines share the 3rd female pipe, the first boiler 1 connects the 3rd female pipe by the first force (forcing) pump 3, and the second boiler 2 connects the 3rd female pipe by the second force (forcing) pump 4.
The beneficial effects of the utility model are: guarantee on the one hand frequency conversion small pump high-efficiency operation, realize on the one hand the even running simultaneously of two oxygen-eliminating devices, meet the water yield of boiler normal need, guarantee that the onsite user normally keeps the safety in production.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model low-level deaerator water charging system.
The 1, first boiler wherein, the 2, second boiler, the 3, first force (forcing) pump, the 4, second force (forcing) pump, the 5, first oxygen-eliminating device, the 6, second oxygen-eliminating device, 7, No. 1 small pumps, 8, No. 2 small pumps, 9, No. 3 small pumps, 10, No. 4 small pumps.
The specific embodiment
By Shanxi Taigang Stainless Steel Co., Ltd's moisturizing division field observation is analyzed, main cause is due to the parallel running of two frequency conversion small pumps, efficiency is lower than single pump efficiency on the one hand, because shared female pipe causes interfering with each other, water outlet can not guarantee the permanent liquid level water of two oxygen-eliminating devices simultaneously on the one hand., because the oxygen-eliminating device mounting means is that low level is installed, be arranged on ground level, the water that setting height(from bottom) can not meet after deoxygenation enters boiler simultaneously.Therefore, how to guarantee on the one hand frequency conversion small pump high-efficiency operation, can realize on the one hand the even running simultaneously of two oxygen-eliminating devices, the water after deoxygenation can directly enter boiler, is problem to be solved in the utility model.
As shown in Figure 1, No. 1 small pump and No. 2 small pump export pipelines share first female pipe, No. 3 small pumps and No. 4 small pump export pipelines share second female pipe, first female pipe connects the first oxygen-eliminating device, second female pipe connects the second oxygen-eliminating device, two oxygen-eliminating device export pipelines share the 3rd female pipe, and the first boiler connects the 3rd female pipe by the first force (forcing) pump, and the second boiler connects the 3rd female pipe by the second force (forcing) pump.
By using the utility model that following effect is arranged:
1, improve water pump efficiency, by two while operational efficiency 70%, bring up to separate unit operational efficiency 85%;
2, water pump water outlet does not interfere with each other, and has guaranteed the normal safe operation of boiler, solved oxygen-eliminating device due to liquid level warning standby or halting problem, guaranteed that the user normally produces.
3, the water after the oxygen-eliminating device deoxygenation can enter boiler with certain pressure, guarantees that boiler normally moves, and meets user's Production requirement.
