Abstract
The utility model discloses a spray-filling type deaerator. At present, the deaerator adopts a vertical structure and is low in power efficiency, so that the deaerator is only suitable for a small-scale unit, and one unit is equipped with only one deaerator. The conventional deaerator of my company adopts the vertical structure, and the power efficiency is less than 380t/h. The spray-filling type deaerator comprises a water tank (1) provided with a pressure gauge and a temperature gauge, and a deaerator (4) provided with a pressure gauge (2) and a temperature gauge (3), wherein the deaerator is connected at the upper part of the water tank; a liquid level detection cylinder (5), a single-chamber balance container (6) and a group of magnetic flap liquid level meters (7) are arranged at the tail part of the water tank in sequence; a safety valve (8) is connected at the end part of the deaerator; and a steam exhaust pipeline is arranged at the upper part of the deaerator and is connected with a throttling orifice plate (9). The spray-filling type deaerator is used for boiler water supply systems of electric power plants and owned power plants.
Description
Technical field:
the utility model relates to the oxygen-eliminating device device of boiler heating power system in a kind of power station or the commercial production enterprise, is specifically related to a kind of spraying material filling type oxygen-eliminating device.
Background technology:
oxygen-eliminating device equipment is one of equipment indispensable in the boiler feedwater heat regenerative system.Spraying material filling type oxygen-eliminating device is to remove dissolved oxygen and other incondensable gas in anhydrating with the heating power method, thereby improves the quality and the temperature of feedwater, reduces the oxygen corrosion of unit equipment, the thermal efficiency of raising unit.
are present, and oxygen-eliminating device adopts the vertical structure form, and it is less generally to exert oneself, and is only applicable to small-sized unit, and a machine assembly supplies an oxygen-eliminating device.The original oxygen-eliminating device of my company adopts vertical structure, exerts oneself less than 380t/h.Along with the maximization of unit, require to be furnished with the oxygen-eliminating device of exerting oneself more greatly, vertical structure can not meet the demands.
Summary of the invention:
The purpose of
the utility model provides spraying material filling type oxygen-eliminating device a kind of horizontal type structure, that exert oneself greatly, and when under the bigger operating mode of load fluctuation, moving, that all can satisfy boiler water supply under each operating mode contains that oxygen requires and temperature requirement.
Above-mentioned purpose realizes through following technical scheme:
a kind of spraying material filling type oxygen-eliminating device; Its composition comprises: have the water tank of Pressure gauge and thermometer, described water tank upper connects the housing of described oxygen-eliminating device, at described water tank afterbody Level Detection tube, single-compartment balance container and one group of magnetic turnover panel liquid level gauge is housed in order; The end of the housing of described oxygen-eliminating device connects safety valve; The housing top of described oxygen-eliminating device has blow-off line, and described blow-off line connects restricting orifice, and described housing is equipped with bearing.
described spraying material filling type oxygen-eliminating device, described water tank comprises housing, the device that seethes with excitement again, urgent jettison gear, overflow mechanism is housed in the described housing and gives water out, described housing top connects downcomer and steam equalizing pipe.
described spraying material filling type oxygen-eliminating device; Described housing top has one group of spring nozzle, and described spring nozzle connects the female pipe unit of water inlet, and both sides, described shell cover bottom have steam inlet device respectively; In the described housing water spraying tray is housed; The secondary deaerating plant is housed in the described housing, and described secondary deaerating plant comprises orifice plate and packing layer, and described housing two upper lateral parts connect exhaust apparatus.
Beneficial effect:
1. the spring nozzle that adopts of the utility model have special construction and make this product have very strong deoxygenation ability and adapt to the varying duty ability; Especially the high dissolved oxygen of power plant, low temperature moisturizing there are extremely strong adaptive capacity, down all can stable operation at 110% load and sub-load (>=30% load).
2. the water tank of the utility model are the collecting devices of deaerated water, have the storage boiler feedwater, the change of confluent when absorbing varying duty, the function of maintenance balance.
The bigger oxygen-eliminating device of exerting oneself has been made to the problem that prior art exists in
3. the utility model, can be used for the shared oxygen-eliminating device of two units of large-scale unit or small-sized unit, reduces number of devices, reduces cost of investment.Oxygen-eliminating device all satisfies the deoxygenation requirement when separate unit unit operation and two units move simultaneously, equipment adapts to load range and strengthens, and satisfies the needs of fixed pressure operation and sliding pressure operation.
4. the deoxygenation head capsule body internal upper part of the utility model are provided with 16 spring nozzles, have guaranteed that condensed water has atomizing, film-formation result preferably, have guaranteed that condensed water fully contacts with heating steam, carry out the mass transfer heat exchange, have reached the deoxygenation purpose.
5. the utility model also can safely and steadily run in the bigger operating mode of thermograde.Distribute female tubular construction to simplify the outfit of equipment structure through feedwater, bring great convenience for manufacturing and installation.
