Abstract
The utility model relates to a thermal deaerator arranged at a low position, which belongs to a water-feed type thermal deaerating device matched with a steam boiler. The device is characterized in that the device comprises a deaerating tower, a deaerating water tank, a boiler feed pump, an anti-cavitation device and so on, wherein the boiler feed pump is provided with the anti-cavitation device. The device has the advantages that the device contributes to reducing installation space and the cost for civil engineering, and is convenient to manage and maintain; and the cavitation problem of the boiler feed pump is completely eliminated by arranging the anti-cavitation device on the boiler feed pump.
Description
Technical field
The utility model belongs to feedwater thermal deoxygenizing apparatus technical field, relates to the thermal deaerator that a kind of low level is provided with, and this device and the supporting use of steam boiler are by dissolved oxygen and other gas in the heating means removal feedwater, the corrosion that alleviates heat power equipment.
Background technology
At present, according to national standard, evaporation capacity all needs to carry out feedwater deaeration greater than the steam boiler of 2t/h.Usually in order to overcome the cavitation problem of boiler feed pump, traditional thermal deaerator need be installed in 7～14m height, and boiler feed pump need be installed on the ground.Because installing space is big, there is civil engineering cost height, deficiency such as complicated, big, the Operation and Maintenance inconvenience of taking up room is installed.
Anti cavitation device can solve the cavitation problem of boiler feed pump, and anti cavitation device adopts prior art, and its patent No. is ZL93213495.5, and publication number is CN2162550.
The utility model content
The technical problems to be solved in the utility model provides a kind of low level, heating power deaerator.
The technical solution of the utility model is that this device comprises oxygen-removing tower, deoxygenation water tank, boiler feed pump, anti cavitation device etc.
Two-stage deoxygenation assembly is installed in the oxygen-removing tower, and wherein one-level deoxygenation assembly is the skinning device, is the critical piece of heat and mass, arranges according to design parameter and arts demand; Secondary deoxygenation assembly is stainless steel helices, strengthens the carbonated drink contact area, strengthens deaerating effect.
The deoxygenation water tank is used to store deaerated water.
Anti cavitation device is installed on the boiler feed pump.Anti cavitation device is to be made of jet pump, is to adopt the principle design of spraying supercharging.Boiler feedwater pump discharge fraction desalted water enters jet pump, desalted water in the water tank is extracted into the inlet of boiler feed pump, the boiler feedwater pump intake forms a zone that is higher than the deoxygenation tank pressure, the desalted water of boiler feedwater pump intake is in undersaturated condition, therefore boiler feed pump is when carrying the high temperature desalted water, the boiler feedwater pump intake steam bubble can not occur, thereby eliminates the boiler feed pump cavitation.At last, boiler feed pump is delivered into boiler with deaerated water.
Anti-rotating plate is installed on the outlet pipe of deoxygenation water tank, and anti-rotating plate is cross, and is welded by the three-piece metal plate.Be provided with auxiliary heating tube in the deoxygenation water tank.
The beneficial effects of the utility model are that low level, heating power deaerator and boiler feed pump are installed on the same aspect, have reduced installing space, have reduced the civil engineering cost, and management is also convenient directly perceived; Anti cavitation device has been installed on the boiler feed pump, has been eliminated the cavitation problem that boiler feed pump produces when carrying high-temperature water.Deaerator storage tank can be used as the condensed water return water tank, can directly recycle waste heat (as condensed water in high temperature, indirect steam etc.), simplifies the system equipment setting, saves investment.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is anti-rotating plate structural representations of the present utility model.
Among the figure: 1 oxygen-removing tower; 2 deoxygenation water tanks; 3 anti cavitation devices; 4 boiler feed pumps; 5 skinning devices; 6 stainless steel helices; 7 anti-rotating plates; 8 auxiliary heating tubes; A, b and c are the three-piece metal plates.
The specific embodiment
Be described in detail specific embodiment of the utility model below in conjunction with technical scheme and accompanying drawing.
Embodiment:
The utility model is made up of oxygen-removing tower 1, deoxygenation water tank 2, anti cavitation device 3 and boiler feed pump 4.Oxygen-removing tower 1 vertical being installed on the horizontal deoxygenation water tank 2.
Oxygen-removing tower 1 in the utility model comprises skinning device 5 and stainless steel helices 6.
Heating steam enters oxygen-removing tower 1 by air intake, and in oxygen-removing tower 1 on flow; Feedwater enters oxygen-removing tower 1 by water inlet, and at first in skinning device 5, feedwater fully contacts with heating steam, and feedwater is heated and finishes most of oxygen removal process; Then feedwater drops in the stainless steel helices 6, and feedwater finally is heated by steam the deoxygenation temperature, and the gas in the feedwater discharges fully; Feedwater at last falls into deoxygenation water tank 2;
Deaerated water (104 ℃ of saturation waters) enters in the anti cavitation device 3 through anti-rotating plate 7.In anti cavitation device 3, deaerated water is extracted into the inlet of boiler feed pump 4 by anti cavitation device 3; At the inlet of boiler feed pump 4, the part kinetic energy of deaerated water is converted into the pressure energy, forms a higher pressure area, and deaerated water is in undersaturated condition under this pressure, and therefore the inlet at boiler feed pump 4 can not form cavitation.
The utility model is realized the low level setting of thermal deaerator by above-mentioned measure.
The boiler feed pump 4 that the utility model adopts, anti cavitation device 3, valve, instrument and switch board adopt prior art.
