Description

Technical Field

[0001] The utility model relates to the technical field of deaerators, in particular to a vertical deaerator. Background Art

[0002] Deaerators can be categorized as thermal deaerators, headless deaerators, and rotary film deaerators. A rotary film deaerator includes a water storage tank and a deaerator head. The deaerator head is often mounted on the water tank and connects water and heating steam. The water and heating steam undergo heat exchange, removing oxygen and other gases from the water. The deaerated water then flows into the water tank for storage. However, during the deaeration process, water is often sprayed into the deaerator head, resulting in a shorter contact time between the water and heating steam, incomplete heat exchange, and a higher oxygen content in the water. Long-term use of water with a high oxygen content can cause the equipment to rust quickly, shortening its service life. Utility Model Content

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0029] like Figure 1-6 As shown, a vertical deaerator includes a water storage tank 2 and further includes:

[0030] The deaerator 1 is provided on the water storage tank 2 and is provided with a liquid adding pipe 111 and an air inlet pipe 151;

[0031] The water storage tray 17 is arranged at the liquid outlet of the liquid adding pipe 111. The water storage tray 17 is provided with an arc-shaped baffle 172. The arc-shaped baffle 172 is provided with a circular array of water leakage holes 171. A heat conductive layer 112 is formed between the water storage tray 17 and the deaerator 1;

[0032] The drainage tray 19 is arranged at the air outlet of the air inlet pipe 151 , and a tower tray 18 is arranged between the drainage tray 19 and the water storage tray 17 .

[0033] Specifically, the deaerator 1 includes a liquid adding end 11 and an air inlet end 15, and the liquid adding pipe 111 and the air inlet pipe 151 are respectively connected to the liquid adding end 11 and the air inlet end 15, so that the liquid adding pipe 111 is connected to the water into the deaerator 1, and the water flow will flow to the water storage tray 17 in advance. Due to the obstruction of the arc-shaped baffle 172, the water will accumulate on the water storage tray 17 and will continuously drip onto the tower tray 18 through the water leakage hole 171. When the water flow is too large, the water will flow from the axis of the water storage tray 17. The water overflows and flows onto the tower plate 18 to form heat exchange with the hot steam, and the air inlet pipe 151 leads the hot steam into the deaerator 1. The hot steam will be blown onto the guide plate to further improve the heat exchange effect between water and hot steam. Then the hot steam will rise on the deaerator 1 and stay at the heat conductive layer 112. At this time, the hot steam forms heat exchange with the accumulated liquid on the water storage tray 17. When the gas pressure in the deaerator 1 is too high, part of the gas will be discharged through the pressure relief valve 4 to reduce the gas pressure in the deaerator 1.

[0034] As an embodiment further provided by the present invention, the drainage plate 19 includes an inclined portion 191, and a windshield 153 facing the inclined portion 191 is provided on the air outlet of the air inlet pipe 151. The deoxygenated water will flow into the water storage tank 2 along the inclined portion 191, and the hot steam will be blown straight onto the windshield 153 through the air inlet pipe 151. Under the action of the windshield 153, the hot steam flows toward the inclined portion 191, further improving the deoxygenation effect on the water. A support ring 152 is provided on the drainage plate 19, and the support ring 152 cooperates with the air inlet pipe 151 to improve the support effect on the air inlet pipe 151.

[0035] As an embodiment further provided by the present invention, the tower plate 18 includes a support plate 181, a tray 182 and a support column 185. The tray 182 is matched with the support plate 181 through the support column 185. The support column 185 is rotatably connected with a rotating ring 184. The axis of the rotating ring 184 is threadedly connected with a clamping block 183. The clamping block 183 is engaged with the support plate 181. A circular baffle is provided at the axis of the support plate 181. The circular baffle is used to disperse the water falling from the water storage plate 17 and make the water fall onto the tray 182, thereby improving the deoxygenation effect of the hot steam.

[0036] As an embodiment further provided by the present invention, a linear array of baffles 188 is provided on the tray 182, a water storage tank 187 is provided on the baffles 188, and a drip hole 186 is provided in the water storage tank 187. When water drips, it will drip into the water storage tank 187, reducing the dripping speed of the water flow and improving the deoxygenation effect.

[0037] As an embodiment further provided by the present invention, at least two groups of trays 182 are provided, and the baffles 188 in the two groups of trays 182 are vertically arranged to improve the contact effect with water. When multiple groups of trays 182 are provided, the rotating ring 184 can be rotated to make the block 183 slide axially. At this time, the tray 182 can be rotated to adjust the angle of the baffle 188.

[0038] As an embodiment further provided by the present invention, a filter box 16 is provided in the deoxygenation tower 1, and an impeller 167 and a filter screen 166 are respectively provided in the filter box 16. A nozzle 114 facing the impeller 167 is clamped on the liquid outlet of the liquid adding pipe 111, and the nozzle 114 sprays water to control the rotation of the impeller 167 to scrape the filter screen 166. The nozzle 114 is set in a cone shape to improve the spray effect of the water flow. The water flow is sprayed onto the blades of the impeller 167 through the nozzle 114, so that the impeller 167 is located in the filter box 16 and rotates to continuously scrape the scale and impurities on the filter screen 166, and scrapes them into the storage box 13 for storage.

[0039] As an embodiment further provided by the present invention, an arc block 165 is provided on the filter box 16 , and the arc block 165 improves the water blocking effect and reduces the water from entering the filter box 16 .

[0040] As an embodiment further provided by the present invention, a receiving box 13 cooperating with the filter box 16 is provided on the deaerator tower 1, and a water outlet 131 is provided in the receiving box 13. A protective cover 12 is rotatably provided on the deaerator tower 1, and the protective cover 12 is fitted with the deaerator tower 1 to protect the receiving box 13. The receiving box 13 can be pulled from the protective cover 12 to separate the receiving box 13 from the deaerator tower 1, thereby removing impurities in the receiving box. Furthermore, after the receiving box 13 is removed, the water storage tray 17, the tower tray 18 or the drainage tray 19 can be maintained.

[0041] As a further embodiment provided by the present invention, a water baffle 164 is provided on the filter box 16. One end of the water baffle 164 is rotatably connected to the filter box 16, and the other end is against the receiving box 13, thereby having a blocking effect on the water flow.

[0042] As an embodiment further provided by the present invention, a sealing ring 14 is provided between the deaerator tower 1 and the water tank 2. The sealing ring 14 improves the sealing effect between the deaerator tower 1 and the water tank 2. A base 3 is provided at the bottom of the water tank 2 to improve the overall supporting effect.

[0043] Working principle: The water that needs to be deoxygenated is introduced into the deoxygenation tower 1 through the liquid adding pipe 111. The water will be sprayed from the nozzle 114 to the blades of the impeller 167, so that the impeller 167 rotates and continuously scrapes the filter 166 to remove impurities on the filter 166. Part of the water will flow from the filter 166 to the water storage tray 17, and a small part will flow into the containing box 13 and flow from the water outlet 131 to the water storage tray 17. Due to the action of the arc baffle 172, the water will accumulate on the water storage tray 17 and conduct heat. The hot air flow in layer 112 fully exchanges heat, improving the deoxygenation effect on water. At the same time, water will continue to drip onto the tower plate 18 along the leakage hole 171, and the heat exchange effect between water and hot steam is further improved through the tower plate 18. At this time, most of the oxygen in the water has been removed, and then it flows from the tower plate 18 to the drainage plate 19. The air inlet pipe 151 leads the hot steam through the wind shield 153, changes the flow direction of the hot steam, and blows it onto the inclined part 191, where it comes into contact with the water flow, and then flows out of the deaerator tower 1 and is stored in the water tank 2.
