Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
A kind of automatic adjustable oxygen-eliminating device as shown in Figure 1,2 and 3, comprise water tank 1, water tank 1 is connected with rotating-film deaerator oxygen-removing tower 2, skinning device 3, trickle comb layer 4, packing layer 5 and point vapour device 6 is provided with from top to bottom successively in rotating-film deaerator oxygen-removing tower 2, four dissolved oxygen sensors 7 are provided with in described water tank 1, described dissolved oxygen sensor 7 is connected with the control cabinet 8 be arranged on outside water tank 1, control cabinet 8 is connected with control valve 9 by wire, and described control valve 9 is arranged in point steam inlet pipe of vapour device 6 10.Described control valve 9 of the present utility model refers to have and surges or the control valve of electric operator or control valve, and control valve is the main Types of actuator, by accepting the control signal that regulation unit exports, removes alter flow by power operation.The oxygen content of deaerated water is set an acceptability limit, the peak of this acceptability limit should a little less than the acceptance value of national regulation, when oxygen-eliminating device works, oxygen content numerical value in the deaerated water collected is averaged by four dissolved oxygen sensors 7 by control cabinet 8, if the mean value recorded is higher than the peak of the acceptability limit of setting, then control cabinet 8 is by increasing the aperture of control valve 9, makes more high-temperature steam enter this device, the oxygen content in deaerated water is reduced within the scope of acceptance value.If the oxygen content in deaerated water is lower than the minimum of the acceptability limit of setting, then control cabinet 8 is by reducing the aperture of control valve 9, reduce high-temperature steam and enter this oxygen-eliminating device, make the oxygen content height in deaerated water within the scope of the acceptance value of setting, therefore can save the use amount of high-temperature steam, thus reach the object reducing energy consumption.
In technique scheme, four dissolved oxygen sensors 7 are uniform along the axial level of water tank 1.The uniform dissolved oxygen sensor 7 of level can make the data that collect more accurate.
In technique scheme, described point of vapour device 6 comprises steam inlet pipe 10, steam inlet pipe 10 one end is communicated with vapour source, the other end is connected with the sub-steam pipe 11 vertically arranged, sub-steam pipe 11 two ends are closed respectively by upper cover plate 12 and lower cover, and upper cover plate 12 diameter is greater than (slightly greatly) sub-steam pipe 11 external diameter, and sub-steam pipe 11 is provided with vertical kidney ellipsoid steam vent 13, described steam vent 13 is uniformly distributed in sub-steam pipe 11, and described sub-steam pipe 11 is connected with support 14.Steam inlet pipe 10 is axially connected with sub-steam pipe 11 radial direction, and namely steam inlet pipe 10 level, sub-steam pipe are vertically arranged, and increasing the diameter of sub-steam pipe 8 and reducing the height dividing vapour device 6 while not reducing quantity of steam, can make the height reduction of whole equipment like this.Upper cover plate 12 diameter is a bit larger tham sub-steam pipe 11 external diameter, is to stop that water droplet is dripped into sub-steam pipe 11 by steam vent 13.
In technique scheme, described sub-steam pipe 11 comprises inner sleeve 17 and outer tube 18, and described outer tube 18 internal diameter is the twice of inner sleeve 17 external diameter.If the diameter of sub-steam pipe 11 is excessive, then its inner space is excessive, and its environment for use air pressure is too low, high-temperature steam easily from from steam inlet pipe 10 more close to steam vent overflow, then steam maldistribution in oxygen-eliminating device, causes deaerating effect bad.Therefore, sub-steam pipe 11 is designed to the structure of inner sleeve 17 and outer tube 18, reduce sub-steam pipe 11 internal capacity, then high-temperature steam enters after in sub-steam pipe 11 from steam inlet pipe 10, steam pressure difference in space between inner sleeve 17, outer tube 18 will reduce, make the high-temperature steam that gushes out from each steam vent 13 evenly.The ratio of outer tube 18 internal diameter and inner sleeve 17 external diameter is 2, is so more conducive to pressure in sub-steam pipe average.
In technique scheme, in the outlet pipe 15 bottom described water tank 1, be provided with backflow non-return valve 16.Water after backflow non-return valve 16 can prevent deoxygenation pours in down a chimney in inlet water tank 1, increases work efficiency.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
