Abstract
The utility model discloses a novel vacuum deaerating plant which comprises a deaerator unit and is characterized by comprising a water storage container and a vacuum device, wherein the water storage container is provided with a heat exchange device for carrying out heat exchange on a water medium inside the water storage container; the water medium which obtains heat by heat exchange is conveyed to a deaerating head of the deaerator unit by a pipeline; the vacuum device is connected to the deaerating head of the deaerator unit. The novel vacuum deaerating plant has the benefits that the novel vacuum deaerating plant not only can carry out water supply and deaeration on a boiler, but also does not require steam of a steam boiler, and can be installed at a low level.
Description
Technical field
The utility model relates to a kind of steam boiler feedwater deaeration, the deoxygenation of hot water heating stove's supplementary feed and other of being applicable to need to be 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, current are carried out to disturbance simultaneously, steam is further fully contacted 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 from water, be diffused in steam, to reach the object of deep deoxygenization.Thermal de-aeration has consumed a large amount of steam of steam boiler, has reduced exerting oneself of steam boiler.
Utility model content
The purpose of this utility model is exactly in order to address the above problem, and a kind of novel evacuated de-aerator plant is provided, and it can not only not need to consume again the steam of steam boiler itself to boiler supply water deaerating, can also install by low level.
To achieve these goals, the utility model 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 that carries out heat exchange to tank internal water medium, through heat exchange and the water medium that obtains heat is delivered to the deoxygenation head of deoxygenator unit by pipeline;
Vacuum, it is connected in the deoxygenation head of deoxygenator unit.
As the utility model, comparatively it is desirable to, described heat-exchanger rig is the snakelike heat transfer tube that is arranged in tank inside.
As the utility model, comparatively it is desirable to, between described tank and deoxygenator unit, be provided with water transfer pump.
As the utility model, comparatively it is desirable to, described tank has the transfer line of the deoxygenator body that leads to deoxygenator unit, and it is provided with control valve.
The utlity model has following beneficial effect: can not only be to boiler supply water deaerating, and do 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
For technique means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, novel evacuated de-aerator plant, it comprises the deoxygenator unit K consisting of deoxygenator body 1 and the deoxygenation head of being located at deoxygenator body, adopt the water storage apparatus of tank 4(such as the body structure of heat regenerator), heat regenerator 7 carries out heat exchange to tank internal water medium, through heat exchange and the water medium that obtains 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 in the deoxygenation 2 of deoxygenator unit.
As another embodiment of the present utility model, described heat-exchanger rig is the snakelike heat transfer tube that is arranged in tank inside, in the evenly distributed inner chamber with tank of this heat transfer tube.
Between described tank and deoxygenator unit, be provided with water transfer pump 5, this water transfer pump need to meet the ability of carrying thermal medium, when the tank that low level is installed is delivered to the deoxygenation of deoxygenator unit, enough pressure guarantees are provided, as another kind, select to be, the mounting height of tank is higher than deoxygenator unit, and hot-fluid is controlled and can be realized from high to low flowing by valve.
Described tank has the transfer line 8 of the deoxygenator body 1 that leads to deoxygenator unit, and it is provided with control valve.
In the deoxygenator body bottom of deoxygenator unit, have by valve and control and the outside water port A of draining, and valve, service pump are set and to the feed water inlet J of boiler water supply at deoxygenator body.
In this device, selected pump valve need to be considered the characteristic of delivery medium and select, and such as water transfer pump, need to select hot water pump.
By vacuum, deoxygenator body is vacuumized, reduce the pressure of deoxygenator body, adopt heat regenerator to heat water tank (tank), then by water transfer pump (service pump) 5 pressurizations, send into deaeration in condenser head, water in deoxygenator body gasifies at suitable vacuum pressure and temperature, oxygen in water and other gas are taken out of to the water surface, be diffused in steam, reach the effect of deoxygenation.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvement of carrying out under the prerequisite that does not depart from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
