Abstract
The utility model discloses an overflow water seal device for a low-temperature deaerator. The top end of the overflow water seal device is respectively connected with a deaerization water tank and a raw water tank through water pipes, and the bottom end of the overflow water seal device is connected with a sewerage system. The overflow water seal device comprises a plurality of sequentially connected overflow water seals, a water replenishing device is arranged at the lower end of the overflow water seal at the beginning end, an overflow port at the top end of the overflow water seal device at the beginning end is connected with the deaerization water tank through a pipeline, a discharging port at the top end of the overflow water seal at the tail end is connected with the raw water tank through a pipeline, and the overflow port of the overflow water seal at the beginning end and the discharging port of the overflow water seal at the tail end are at the same level. When water is in short of supply, the procedure of manually opening and closing a valve is omitted and atomization is achieved. The overflow port and the discharging port are at the same level, so that not only automatic drainage can be achieved when water at the overflow port exceeds normal water level, but water does not lose when being at the normal level, automatic discharging is achieved when pressure is excessive, and the overpressure discharging function of water seal is achieved.
Description
Technical field
The utility model belongs to the boiler heating power deaeration plant, is specifically related to a kind of overflow water seal apparatus of low pressure oxygen-eliminating device.
Background technology
The water seal of existing low pressure oxygen-eliminating device has the polytypes such as single-stage water seal, twin-stage water seal, multilevel water seal, these water seals are used in the steam boiler thermal de-aeration equipment of being everlasting, water seal must be passed through floor and be installed, increased the installing engineering amount, adopt the water seal eruption of steel pipe and blindness plate weldering bridging structure frequent, the waste water source causes very large energy waste; And need the extra moisturizing point that increases, manually switch moisturizing valve is lost time, waste of manpower.
Summary of the invention
The problems referred to above that exist in order to overcome the prior art field, the purpose of this utility model is, a kind of overflow water seal apparatus of low pressure oxygen-eliminating device is provided, and solving the low pressure oxygen-eliminating device needs extra increase moisturizing source and water seal to pass through floor, increases the problem of installing engineering amount.
The overflow water seal apparatus of the low pressure oxygen-eliminating device that the utility model provides, the top is connected with deoxygenation water tank, raw water box respectively by water pipe, the bottom is connected with drainage by valve, it comprises the overflow water seal that several connect successively, the lower end of described top overflow water seal is provided with water replanishing device, the top overflow water binds and holds overfall to be connected with the deoxygenation water tank by pipeline, the bind floss hole of end of terminal overflow water is connected with raw water box by pipeline, and the floss hole level height maintenance of top water seal overfall and terminal water seal in the same horizontal line.Described water replanishing device is the water inlet interface that is arranged on overflow water seal lower end, top, and the water inlet interface is connected with deoxygenation water tank lower end interface by water pipe.The pipeline bending part that described terminal overflow water seal is connected with raw water box all adopts elbow to connect.
The overflow water seal apparatus of the low pressure oxygen-eliminating device that the utility model provides, its beneficial effect is, increased the bottom water replanishing device, reduced extra filling up area, do not need to add in addition the moisturizing source, and realized that water seal uninterruptedly supplies water, when having solved lack of water, the operation of hand switch valve has reduced workman's routine work amount to a great extent, realized automation, and overfall and floss hole are positioned at the same level height, both can realize that overfall surpasses ordinary water level and automatically drains, and can guarantee again to be lower than not dehydration of ordinary water level, automatic-discharging when superpressure, the overpressure relief function of realization water seal.Reduce the water seal vertical range, made water seal needn't pass through floor, reduced on-the-spot installing engineering amount; Increase elbow and replace part steel pipe and blind plate weldering bridging structure, make the fluid eruption more smooth.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model embodiment;
Fig. 2 is the structural representation that overflow water seal in top is connected with the deoxygenation water tank among Fig. 1.
Mark among the figure:
1. raw water box; 2. deoxygenation water tank; 3. drainage; 4. water inlet interface; 5. overfall; 6. floss hole; 7. top overflow water seal; 8. terminal overflow water seal.
The specific embodiment
With reference to the accompanying drawings, in conjunction with the embodiments, the overflow water seal apparatus of the low pressure oxygen-eliminating device that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1-Fig. 2, the overflow water seal apparatus of the low pressure oxygen-eliminating device of present embodiment, the top by elbow and seamless steel pipe respectively with deoxygenation water tank 2, raw water box 1 connects, the bottom is connected with drainage 3 by valve, it comprises the overflow water seal that several connect successively, the lower end of described top overflow water seal 7 is provided with water replanishing device, overflow water seal 7 top overfalls 5 in top are connected with deoxygenation water tank 2 by pipeline, the floss hole 6 on terminal overflow water seal 8 tops is connected with raw water box 1 by seamless steel pipe and elbow, and the floss hole 6 of top water seal overfall 5 and terminal water seal highly in the same horizontal line.Described water replanishing device is the water inlet interface 4 that is arranged on overflow water seal 7 lower ends, top, and water inlet interface 4 is connected by 2 times end interfaces of water pipe and deoxygenation water tank.The pipeline bending part that described terminal overflow water seal 8 is connected with raw water box 1 all adopts elbow to connect.
Increased the bottom water replanishing device, reduced extra filling up area, do not needed to add in addition the moisturizing source, and realized that water seal uninterruptedly supplies water, when having solved lack of water, the operation of hand switch valve has realized automation, and overfall 5 is positioned at the same level height with floss hole 6, both can realize that overfall surpassed ordinary water level and automatically drains, can guarantee again to be lower than not dehydration of ordinary water level, automatic-discharging when superpressure, the overpressure relief function of realization water seal.Reduce the water seal vertical range, made water seal needn't pass through floor, reduced on-the-spot installing engineering amount; Increase elbow and replace part steel pipe and blind plate weldering bridging structure, make the fluid eruption more smooth.In addition, can increase the sealing height of overflow water seal progression and overflow water seal according to the needs of actual conditions, better meet the needs of Practical Project.
