Abstract
The invention discloses a novel vacuum deoxygenization device comprising a deoxygenization device unit. The device is characterized in also comprising a water storage container and a vacuum device. The container is provided with a heat exchange device used for carrying out heat exchange upon water medium in the water storage container. Water medium obtained after heat exchange and with heat energy is delivered to a deoxygenization head of the deoxygenization device unit through a pipeline. The vacuum device is connected to the deoxygenization head of the deoxygenization device unit. The device provided by the invention has the following advantages: with the device, boiler feed-water deoxygenization can be carried out; steam of the boiler is not needed; and the device can be mounted at a lower position.
Description
Technical field
The present invention relates to a kind of be applicable to steam boiler feedwater deaeration, the deoxygenation of hot water heating stove's supplementary feed and other need except the novel evacuated de-aerator plant of the system of the middle gas that anhydrates.
Background technology
At present, steam boiler feedwater deaeration mainly adopts thermal de-aeration, the steam of thermal de-aeration comes from steam boiler itself, deoxygenation head is mainly sent in heating steam, mix with the moisturizing of spray, boosting steam by comb from sending into deoxygenation water tank under water, heating steam and water Hybrid Heating, disturbance is carried out to current simultaneously, steam is fully contacted further with saturation water, and from water, take the dissolved oxygen in water and other incondensable gas out of the water surface, dissolved oxygen will be followed Henry's law and be diffused into from water in steam, to reach the object of deep deoxygenization.Thermal de-aeration consumes a large amount of steam of steam boiler, decreases exerting oneself of steam boiler.
Summary of the invention
Object of the present invention is exactly to solve the problem, and provides a kind of novel evacuated de-aerator plant, and it to boiler supply water deaerating, can not only not need again the steam consuming steam boiler itself, can also install by low level.
To achieve these goals, the present invention adopts following technical scheme:
Novel evacuated de-aerator plant, it comprises deoxygenator unit, it is characterized in that, also comprises:
Tank, it has the heat-exchanger rig carrying out heat exchange to tank internal water medium, through heat exchange and the water medium obtaining heat by Cemented filling to the deoxygenation head of deoxygenator unit;
Vacuum, it is connected to the deoxygenation head of deoxygenator unit.
As the present invention, it is preferable that, described heat-exchanger rig is the snakelike heat transfer tube being arranged in tank inside.
As the present invention, it is preferable that, between described tank and deoxygenator unit, be provided with water transfer pump.
As the present invention, it is preferable that, described tank has the transfer line of the deoxygenator body leading to deoxygenator unit, and it is provided with control valve.
The present invention has following beneficial effect: to boiler supply water deaerating, and can not only not need the steam of steam boiler itself, and can install by low level.
Accompanying drawing explanation
Fig. 1 is novel evacuated de-aerator plant structural representation.
Embodiment
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1, novel evacuated de-aerator plant, it comprises the deoxygenator unit K be made up of with the deoxygenation head being located at deoxygenator body deoxygenator body 1, adopt the water storage apparatus of the tank 4(such as body structure of heat regenerator), heat regenerator 7 carries out heat exchange to tank internal water medium, through heat exchange and the water medium obtaining heat is delivered to the deoxygenation 2 of deoxygenator unit by pipeline 6, pipeline 6 is provided with control valve; Vacuum 3, it is connected to the deoxygenation 2 of deoxygenator unit.
As an alternative embodiment of the invention, described heat-exchanger rig is the snakelike heat transfer tube being arranged in tank inside, and this heat transfer tube is evenly distributed with the inner chamber of tank.
Water transfer pump 5 is provided with between described tank and deoxygenator unit, this water transfer pump needs the ability meeting conveying thermal medium, when the tank installed by low level is delivered to the deoxygenation head of deoxygenator unit, enough pressure guarantees are provided, be alternatively, the mounting height of tank is higher than deoxygenator unit, and hot-fluid can be realized from high to low flowing by Valve controlling.
Described tank has the transfer line 8 of the deoxygenator body 1 leading to deoxygenator unit, and it is provided with control valve.
There is at the deoxygenator body lower part of deoxygenator unit the water port A of the outside draining by Valve controlling, and valve, service pump and to the feed water inlet J of boiler water supply are set at deoxygenator body.
Pump valve selected in this device needs to consider the characteristic of delivery medium and selects, and such as water transfer pump needs to select hot water pump.
By vacuum, deoxygenator body is vacuumized, reduce the pressure of deoxygenator body, heat regenerator is adopted to heat water tank (tank), then pressurizeed by water transfer pump (service pump) 5 and send into deaeration in condenser head, water in deoxygenator body gasifies under suitable vacuum pressure and temperature, oxygen in water and other gas are taken out of the water surface, is diffused in steam, reach the effect of deoxygenation.
The foregoing is only the preferred embodiment of the present invention, protection scope of the present invention is not limited in above-mentioned embodiment, and every technical scheme belonging to the principle of the invention all belongs to protection scope of the present invention.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present invention, these improvement also should be considered as protection scope of the present invention.
