Description

Technical Field

[0001] This utility model relates to the field of boiler technology, and in particular to a deoxygenation device for demineralized water. Background Technology

[0002] During boiler operation, the boiler water needs to be desalinated by a desalination station.

[0003] The existing patent with publication number CN212640016U discloses a deoxygenation device for demineralized water, which includes: a horizontal water tank with a central opening at the top, a demineralized water outlet, and a drain outlet; a vertical cylinder with a demineralized water inlet, a high-level heating steam inlet, and a first safety valve at its upper part; a vertical cylinder fixed above the horizontal water tank with its lower end connected to the opening; a film-forming device disposed in the upper part of the inner cavity of the vertical cylinder; and spaced from top to bottom... A water-spraying plate and a vapor-liquid filter screen are fixed to the lower part of the vertical cylinder's inner cavity. The water-spraying plate has water-spraying holes. A low-level heating steam inlet is set on the lower outer wall of the vertical cylinder. The low-level heating steam inlet is connected through a steam distribution plate fixed to the inner cavity of the vertical cylinder. The steam distribution plate is set below the vapor-liquid filter screen. A cover is set on the top of the vertical cylinder. The cover is equipped with a second safety valve port and a first manhole. A vapor-liquid separator is set in the first manhole. An oxygen vent is set on the first manhole.

[0004] The aforementioned device can evenly distribute the deoxygenated water from the film-forming device onto the vapor-liquid filter screen via a water-spraying plate. During this process, heat exchange can be performed using low-level heated steam to achieve deep deoxygenation, reducing the dissolved oxygen in the deoxygenated water to below 6 μg / L.

[0005] However, when deoxygenating demineralized water, the device directly introduces the demineralized water into the interior of the deoxygenation tower. However, the demineralized water contains suspended solids, particulate matter, or colloids. These impurities directly enter the deoxygenator and deposit on the packing layer or heating element surface, which can easily lead to flow channel blockage and increased pressure drop. The impurities may also cover the inner surface of the deoxygenator, reducing the gas-liquid contact area, hindering oxygen evolution, and resulting in incomplete deoxygenation.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] In the attached diagram, all identical reference numerals refer to the same components.

[0017] like Figure 1-4 As shown, this utility model provides a deoxygenation device for demineralized water, comprising: Water storage tank 1, with a base at the bottom and a connecting seat 2 at the top, and a drain pipe 3 on one side of the water storage tank 1, with a valve at the connection between the drain pipe 3 and the water storage tank 1. The deaerator body 4 is located on one side of the top of the connecting seat 2. The other side of the top of the connecting seat 2 is provided with a pretreatment component 5. The pretreatment component 5 includes a water tank 501, a filter box 502, a limiting seat 504, a filter screen plate 505, an activated carbon plate 506, a sealing plate 507, a motor 508, a stirring rack 509, an electric heating plate 5010, a water pump 5011, a water pumping pipe 5012, and a water supply pipe 503. The water tank 501 is installed on one side of the top of the connecting seat 2. The filter box 502 is located on one side of the top of the water tank 501. The top of the filter box 502 is provided with a water inlet pipe 6, and the bottom of the filter box 502 is provided with a pipe. The filter box 502 is connected to the water tank 501 through the pipe.

[0018] In this embodiment, two limiting seats 504 are installed on both sides of the inside of the filter box 502. A sealing plate 507 is movably arranged on one side of the filter box 502. The filter screen plate 505 and the activated carbon plate 506 are slidably arranged between the limiting seats 504. One end of the filter screen plate 505 and the activated carbon plate 506 are fixedly connected to the sealing plate 507. A handle is provided in the middle of the outer side of the sealing plate 507.

[0019] Specifically, the desalinated water is initially purified by the filter screen 505 and activated carbon plate 506, which can effectively remove larger particulate impurities, odors, residual chlorine and other small molecule impurities from the water, providing a better quality water source for the subsequent deoxygenation process and reducing the impact of impurities on the deoxygenation equipment and subsequent use.

[0020] Furthermore, a motor 508 is installed on one side of the water tank 501, the rotating shaft of the motor 508 extends into the interior of the water tank 501, and a stirring rack 509 is installed thereon. An electric heating plate 5010 is installed on the bottom wall inside the water tank 501, and a water pump 5011 is installed on one side of the top of the water tank 501.

[0021] Specifically, the water tank 501 uses a motor 508 to drive the electric stirring frame 509 to rotate, and the internal bottom wall electric heating plate works simultaneously. This allows the water in the water tank 501 to be heated more evenly, improves heating efficiency, creates good temperature conditions for deoxygenation, and helps to improve the deoxygenation effect.

[0022] Furthermore, a water pump 5012 is installed at the inlet of the water pump 5011, and the water pump 5012 extends into the interior of the water tank 501. A water delivery pipe 503 is installed at the outlet of the water pump 5011, and the other end of the water delivery pipe 503 is connected to the deaerator body 4.

[0023] Specifically, the water pump 5011 achieves stable water delivery through the water pumping pipe 5012 and the water delivery pipe 5013, ensuring that the heated water can accurately and timely enter the deaerator body 4, thus guaranteeing the continuous and stable operation of the entire deaeration system.

[0024] In this embodiment, an air inlet pipe 7 is provided on one side of the deaerator body 4, and the other end of the air inlet pipe 7 extends into the interior of the deaerator body 4 and is equipped with a steam nozzle 8.

[0025] Specifically, the steam nozzle 8 sprays steam evenly, ensuring full contact with the hot water. Combined with the grate plate 9, this increases the contact area and time between the hot water and the steam, effectively improving deoxygenation efficiency and allowing dissolved oxygen in the water to escape rapidly, thus meeting the requirements for water oxygen content.

[0026] In this embodiment, the deaerator body 4 is provided with two grate plates 9 inside, a pressure relief valve 10 is provided at the top of the deaerator, a connecting pipe 11 is provided at the bottom of the deaerator body 4, the bottom of the connecting pipe 11 is connected to the water storage tank 1, and an air outlet pipe is provided on one side of the deaerator body 4.

[0027] Specifically, the pressure relief valve 10 installed at the top of the deaerator body 4 can automatically regulate the pressure inside the tower. When the pressure exceeds the set value, it releases the excess pressure in time to avoid damage to the equipment due to excessive pressure, thus ensuring the safe operation of the deaerator and the entire system.

[0028] Working principle: Desalinated water enters the filter box 502 through the inlet pipe 6 at the top. Inside the filter box 502, the water passes sequentially through the filter screen 505 and the activated carbon plate 506. The filter screen 505 performs preliminary filtration of larger particulate impurities in the water, while the activated carbon plate 506 adsorbs small molecule impurities such as odors and residual chlorine, achieving preliminary water purification. Both the filter screen 505 and the activated carbon plate 506 are slidably disposed between the limiting seats 504 on both sides inside the filter box 502, and one end is fixedly connected to a sealing plate 507 movably disposed on one side of the filter box 502. The filter screen 505 and the activated carbon plate 506 can be easily pulled out for cleaning or replacement using the handle in the middle of the outer side of the sealing plate 507.

[0029] The pre-purified water flows into water tank 501. The motor 508 installed on one side of water tank 501 starts, and its rotating shaft drives the stirring frame 509 installed inside water tank 501 to rotate. At the same time, the electric heating plate installed on the bottom wall of water tank 501 also starts to work, heating the water in water tank 501 and raising the water temperature to create favorable conditions for the subsequent deoxygenation process.

[0030] When the water pump 5011 starts, the water inlet pipe 5012 draws heated water from inside the water tank 501, and then delivers the water to the deaerator body 4 through the water outlet pipe 5013, thus realizing the water delivery.

[0031] Steam enters the deaerator body 4 through the inlet pipe 7 and is ejected from the steam nozzle 8 installed at the other end of the inlet pipe 7. The high-temperature steam comes into full contact with the hot water supplied from the water tank 501, causing the dissolved oxygen in the water to escape rapidly, thus achieving the purpose of deaeration.

[0032] During the deoxygenation process, the escaping oxygen and other gases rise to the top of the deoxygenation tower body 4 and are discharged outside the tower through the outlet pipe located on one side of the deoxygenation tower body 4. At the same time, the pressure relief valve 10 installed at the top of the deoxygenation tower body 4 can automatically regulate the pressure inside the tower. When the pressure inside the tower exceeds the set value, the pressure relief valve 10 automatically opens to release the excess pressure and ensure the safe operation of the equipment.

[0033] The two grate plates 9 inside the deaerator body 4 ensure even distribution of hot water entering the tower, increasing the contact area and time between hot water and steam, and improving the deaeration effect. After deaeration, the water flows back to the storage tank 1 through the connecting pipe 11 at the bottom of the deaerator body 4 under gravity for storage and subsequent use.

[0034] When water in the storage tank 1 is needed, the valve located at the connection between the drain pipe 3 and the storage tank 1 on one side can be opened to discharge water from the drain pipe 3.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
