Description

Technical Field

[0001] This utility model relates to the field of deaerator technology, and in particular to a multi-stage spray packing thermal deaerator. Background Technology

[0002] Multi-stage spray packing thermal deaerator is a highly efficient water treatment device, mainly used to remove dissolved oxygen from water to prevent corrosion of downstream pipelines and boiler systems.

[0003] A search of Chinese patent CN212777300U reveals a spray-type thermal deaerator, comprising a deaeration water tank, a deaeration tower, a water supply atomizing device, and a steam distributor. The deaeration water tank has a deaeration water outlet. The deaeration tower is a vertical cylindrical structure with its bottom end connected to the deaeration water tank and its top end equipped with a steam-water separator. The water supply atomizing device includes a water supply pipe embedded in the upper part of the deaeration tower and extending into the tower. Multiple atomizing nozzles with downward-facing nozzles are distributed axially on the water supply pipe. The steam distributor is connected to the lower part of the deaeration tower and located inside the tower, with each steam nozzle facing upward. The deaeration tower contains a Pall ring packing layer and a water spray grate located between the atomizing nozzles and the steam distributor, with the water spray grate positioned above the Pall ring packing layer. This spray-type thermal deaerator can effectively remove oxygen and other non-condensable gases from boiler feedwater to ensure feedwater quality, reduce threats to equipment safety, and improve boiler heat transfer efficiency.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] When the above device is in use, the angle at which the nozzle sprays water mist is fixed, which means that only the filler within the water mist range will come into contact with and react with the water mist. Some filler will not be able to come into contact with the water mist, resulting in a waste of filler performance and thus affecting the reaction efficiency. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a multi-stage spray packing thermal deaerator, which can increase the contact area between water mist and packing, making the reaction more thorough.

[0007] The technical solution to achieve the purpose of this utility model is: a multi-stage spray packing thermal deaerator, including a deaerator tower, an inlet pipe connected to the inside of the deaerator tower installed on the deaerator tower, a water distribution ring set at the top of the inside of the deaerator tower, multiple nozzles set at the bottom of the water distribution ring, a packing box set in the middle of the inside of the deaerator tower, multiple baffle plates fixedly installed on the packing box, and a moving mechanism and a driving mechanism set inside the deaerator tower.

[0008] The event organizers include:

[0009] The installation ring, top rod, and installation spring are installed. The installation ring is fixedly installed inside the deaerator at the position corresponding to the water distribution ring. There are multiple top rods, which are movably installed on the installation ring and correspond to the position of the nozzle. The installation spring is movably sleeved on the top rod.

[0010] The rotating plate, protrusions, and rotating shaft are arranged in the middle of the mounting ring. There are multiple protrusions, which are evenly distributed and fixedly installed on the side wall of the rotating plate. The rotating shaft is fixedly installed at the bottom of the rotating plate and is located inside the heat transfer pipe.

[0011] In some embodiments, the drive mechanism includes a drive motor, transmission gears, and a transmission belt. The drive motor is located inside the deaerator. There are two transmission gears, which are respectively installed at the output end of the drive motor and the bottom of the shaft. The transmission belt is movably sleeved between the two transmission gears, and the transmission belt meshes with the transmission gears for transmission.

[0012] In some embodiments, the deaerator is also equipped with a heat supply pipe and a drain pipe, and an exhaust pipe is installed at the top of the deaerator.

[0013] In some embodiments, a plurality of heat injection pipes are fixedly installed on the side wall of the heat supply pipe, and the heat injection pipes have a plurality of openings.

[0014] In some embodiments, the deaerator is fixedly mounted inside a mounting base, and a packing box is positioned above the mounting base. Multiple ball bearings are movably mounted on the mounting base.

[0015] In some embodiments, the drive mechanism further includes a drive gear and a drive gear ring. The drive gear is fixedly mounted on the output end of the drive motor, and the drive gear ring is fixedly mounted on the bottom of the lowest partition plate. The drive gear and the drive gear ring mesh and transmit power.

[0016] Compared with existing technologies, the significant advantages of this invention are:

[0017] This invention, through the setting of an active mechanism and a driving mechanism, enables the rotating shaft to rotate, which in turn drives the rotating plate and the protrusion to rotate. The rotating plate drives the protrusion to rotate, which in turn causes the protrusion to squeeze the top rod. After being squeezed, the top rod moves towards the nozzle, thereby squeezing the nozzle. Since the nozzle is installed at the bottom of the water distribution ring, the nozzle will swing, and the angle of the water mist sprayed from the nozzle will also change, thereby increasing the contact area between the water mist and the filler, making the reaction more thorough.

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] This utility model provides an improved multi-stage spray-filled thermal deaerator. The technical solution of this utility model is as follows:

[0027] like Figures 1 to 4As shown, a multi-stage spray-filled thermal deaerator includes a deaeration tower 1, an inlet pipe 2 connected to the interior of the deaeration tower 1, a water distribution ring 3 with a hollow circular structure at the top of the interior of the deaeration tower 1, and multiple nozzles 4 at the bottom of the water distribution ring 3. Water requiring deaeration is supplied to the interior of the water distribution ring 3 through the inlet pipe 2, and then the nozzles 4 spray the water out in a mist. A filling box 5 is located in the middle of the interior of the deaeration tower 1, and multiple baffles are fixedly installed on the filling box 5. The deaerator 1 is equipped with a heat supply pipe 7 and a drain pipe 8. The heat supply pipe 7 is connected to a pipe that provides steam to the outside. The heat supply pipe 7 sends steam into the interior of the deaerator 1 and it comes into contact with the packing. The packing then comes into contact with the water mist sprayed from the nozzle 4, thereby deoxygenating the water mist. The drain pipe 8 can discharge the deoxygenated water. The top of the deaerator 1 is equipped with an exhaust pipe 9, which discharges the generated oxygen and water vapor together. The interior of the deaerator 1 is equipped with a moving mechanism and a driving mechanism.

[0028] The moving mechanism includes a mounting ring 10, a top rod 11, a mounting spring 12, a rotating plate 13, protrusions 14, and a rotating shaft 15. The mounting ring 10 is a circular ring structure and is fixedly installed inside the deaerator 1 at the position corresponding to the water distribution ring 3. The top rod 11 is a cylindrical rod, and there are multiple top rods 11. All top rods 11 are movably installed on the mounting ring 10 and correspond to the position of the nozzle 4. The mounting spring 12 is movably sleeved on the top rod 11. The rotating plate 13 is a circular plate and is located in the middle of the mounting ring 10. The protrusions 14 are semi-circular blocks, and there are multiple protrusions 14. The multiple protrusions 14 are evenly distributed and fixedly installed on the side wall of the rotating plate 13. The rotating shaft 15 is a cylindrical structure and is fixedly installed at the bottom of the rotating plate 13. The rotating shaft 15 is located inside the heat supply pipe 7. The rotating shaft 15 can be rotated by the driving mechanism, which in turn drives the rotating plate 13 and the protrusion 14 to rotate. The rotating plate 13 drives the protrusion 14 to rotate, which causes the protrusion 14 to squeeze the push rod 11. After being squeezed, the push rod 11 will move towards the nozzle 4, and then squeeze the nozzle 4. Since the nozzle 4 is installed at the bottom of the water distribution ring 3, the nozzle 4 will swing. At this time, the angle of the water mist sprayed by the nozzle 4 will also change, thereby increasing the contact area between the water mist and the packing and making the reaction more thorough.

[0029] The drive mechanism includes a drive motor 16, a transmission gear 17, and a transmission belt 18. The drive motor 16 is located inside the deaerator 1. There are two transmission gears 17, which are respectively installed at the output end of the drive motor 16 and the bottom of the rotating shaft 15. The transmission belt 18 is movably sleeved between the two transmission gears 17. The transmission belt 18 meshes with the transmission gears 17 for transmission. When the drive motor 16 is started, the drive motor 16 drives the transmission gear 17 to rotate, which in turn drives the rotating shaft 15 to rotate through the other transmission gear 17 and the transmission belt 18.

[0030] Multiple heat injection pipes 23 are fixedly installed on the side wall of the heat pipe 7. The heat injection pipe 23 is a cylindrical pipe with multiple openings 24. Steam can be sent into the packing to heat the packing through the heat injection pipe 23 and the openings 24. An installation base 21 is fixedly installed inside the deaerator tower 1. The installation base 21 is a circular structure. The packing box 5 is set above the installation base 21. Multiple balls 22 are movably installed on the installation base 21. The balls 22 are spherical structures.

[0031] The drive mechanism also includes a drive gear 19 and a drive gear ring 20. The drive gear 19 is fixedly installed on the output end of the drive motor 16. The drive gear ring 20 is a circular structure and is fixedly installed on the bottom of the lowest partition plate 6. The drive gear 19 and the drive gear ring 20 mesh and drive each other. When the drive motor 16 is started, the drive gear 19 will also rotate. The drive gear 19 meshes with the drive gear ring 20, which can drive the packing box 5 and the partition plate 6 to rotate. The heat injection pipe 23 is different, which allows the heat injection pipe 23 to stir the packing inside the packing box 5 and the partition plate 6, further increasing the contact area between the packing and the water mist and improving the reaction effect.

[0032] The specific working method is as follows:

[0033] Through the arrangement of the moving mechanism and the driving mechanism, the driving mechanism can make the rotating shaft 15 rotate, which in turn drives the rotating plate 13 and the protrusion 14 to rotate. The rotating plate 13 drives the protrusion 14 to rotate, which causes the protrusion 14 to squeeze the top rod 11. After being squeezed, the top rod 11 will move towards the nozzle 4, and then squeeze the nozzle 4. Since the nozzle 4 is installed at the bottom of the water distribution ring 3, the nozzle 4 will swing. At this time, the angle of the water mist sprayed by the nozzle 4 will also change, thereby increasing the contact area between the water mist and the filler, making the reaction more thorough.

[0034] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
