Description

Technical Field

[0001] This utility model relates to the field of water deoxygenation technology, specifically to a deoxygenator device. Background Technology

[0002] The deaerator is a key piece of equipment in a boiler thermal system, its main function being to efficiently remove dissolved oxygen and other corrosive gases from the feedwater. It uses high-temperature steam to disrupt the dissolution conditions of oxygen in water, causing it to escape. This prevents corrosion of metal components such as boilers and pipes, ensuring system safety, extending equipment lifespan, and improving operational economy.

[0003] Chinese utility model patent document CN219950565U discloses an adjustable spray structure for a deaerator. This device, through the combination of a rotating tube, a first connecting tube, and a rotating joint, allows water to be pumped into the rotating tube via a first water pump. Water is then sprayed out through nozzles on the first connecting tube, thus creating a spray pattern within the housing. When the spray position needs adjustment, a motor can be activated, causing the rotating tube to rotate. This rotation, in turn, causes the first connecting tube and nozzles to rotate around the rotating joint, resulting in a rotary spray pattern. This allows for adjustment of the spray range, ensuring even contact between the spray and the steam within the housing. However, the fixed installation of the steam pipe in this device easily leads to uneven steam distribution, thus affecting deaeration efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a deaerator device that solves the problem that the steam pipes in existing deaerators are fixedly installed, which easily leads to uneven steam distribution and thus affects deaeration efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A deaerator device includes a deaerator tank. The deaerator tank has an exhaust pipe and a drain pipe at its upper and lower ends, respectively. A constant pressure valve is installed on the exhaust pipe. A water inlet pipe is rotatably connected to the top of the deaerator tank in a sealed manner. The top end of the water inlet pipe is connected to a water supply pipe via an upper rotating joint. One end of the water inlet pipe, inside the deaerator tank, is connected to a circular water pipe via a horizontally arranged transverse water pipe. Vertically downward-facing nozzles are evenly arranged on the outer ring side of the circular water pipe. An air inlet pipe is rotatably connected to the bottom of the deaerator tank in a sealed manner. The bottom end of the air inlet pipe is connected to an air supply pipe via a lower rotating joint. One end of the air inlet pipe, inside the deaerator tank, is connected to a circular air pipe via a horizontally arranged transverse air pipe, and vertically upward-facing air outlets are evenly arranged on its top side. The deaerator tank is equipped with a drive mechanism for rotating the circular water pipe and the circular air pipe.

[0006] A further technical solution is that the driving mechanism includes a rotating rod, which is horizontally rotatable between the annular water pipe and the annular air pipe, and a conical transmission gear is sleeved on its outer side. The bottom end of the water inlet pipe is fixedly connected to a vertically arranged upper rotating rod, and the end of the upper rotating rod is provided with an upper conical gear that meshes with the conical transmission gear. The top end of the air inlet pipe is fixedly connected to a vertically arranged lower rotating rod, and the end of the lower rotating rod is provided with a lower conical gear that meshes with the conical transmission gear. A motor is installed on the outer side of the deaerator, and the output shaft of the motor is connected to one end of the rotating rod for transmission.

[0007] A further technical solution is to connect paddles arranged in a circular array on the outer sides of the upper and lower rotating rods.

[0008] A further technical solution is to install a retention net inside the deaerator between the patter and the annular gas pipe, and to allow the lower rotating rod to rotate through the retention net.

[0009] A further technical solution is to have a scraper on the outside of the intake pipe, with the bottom side of the scraper sliding against the inner bottom wall of the deaerator.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a driving mechanism drives the circular water pipe and the circular air pipe to rotate. High-temperature water vapor is transported into the circular air pipe through the air supply pipe, the air inlet pipe, and the horizontal air pipe, and then sprayed out through the air outlet. At the same time, water is transported into the circular water pipe through the water inlet pipe, the water supply pipe, and the horizontal water pipe, and the water is sprayed out through the nozzle to form a water mist. The driving mechanism drives the circular water pipe and the circular air pipe to rotate, and the rotation of the circular air pipe drives the air outlet to rotate, thereby allowing the high-temperature water vapor to cover a wider and more uniform area. This avoids the high-temperature water vapor being sprayed out through the air outlet and only impacting a fixed point, resulting in uneven distribution of high-temperature water vapor and affecting deoxygenation efficiency. At the same time, the rotation of the circular water pipe drives the rotation of the nozzle, thereby ensuring that the water mist sprayed from the nozzle can be well diffused into the entire deoxygenation tank.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0015] Example 1 Reference Figure 1 This utility model discloses a deaerator device, including a deaerator tank 1. The deaerator tank 1 has an exhaust pipe 2 and a drain pipe 3 at its upper and lower ends, respectively. A constant pressure valve 4 is installed on the exhaust pipe 2. A water inlet pipe 5 is rotatably connected to the top of the deaerator tank 1. The top end of the water inlet pipe 5 is connected to a water supply pipe 7 via an upper rotating joint 6. One end of the water inlet pipe 5, inside the deaerator tank 1, is connected to a circular water pipe 9 via a horizontally arranged horizontal water pipe 8. Vertically downward-facing nozzles 10 are evenly arranged on the outer ring side of the circular water pipe 9. An air inlet pipe 11 is rotatably connected to the bottom of the deaerator tank 1. The bottom end of the air inlet pipe 11 is connected to an air supply pipe 13 via a lower rotating joint 12. One end of the air inlet pipe 11, inside the deaerator tank 1, is connected to a horizontally arranged horizontal air supply pipe 7. Pipe 14 is connected to an annular air pipe 15, and vertically upward air outlets 16 are evenly arranged on its top side. The deaerator 1 is equipped with a drive mechanism for driving the annular water pipe 9 and the annular air pipe 15 to rotate. The central axis of the water inlet pipe 5 is vertically aligned with the center of the annular water pipe 9, and the central axis of the air inlet pipe 11 is vertically aligned with the center of the annular air pipe 15. At the same time, the connection stability between the annular water pipe 9 and the water inlet pipe 5 and the connection stability between the annular air pipe 15 and the air inlet pipe 11 can be ensured by setting a support rod (not shown in the figure). These are common technical knowledge for those skilled in the art, and those skilled in the art can directly obtain the corresponding installation relationship and structure based on common knowledge.

[0016] In this embodiment, during use, the drive mechanism rotates the annular water pipe 9 and the annular air pipe 15, supplying high-temperature water vapor into the annular air pipe 15 through the air supply pipe 13, the air inlet pipe 11, and the horizontal air pipe 14, and spraying it out through the air outlet 16. At the same time, water is supplied to the annular water pipe 9 through the water inlet pipe 5, the water supply pipe 7, and the horizontal water pipe 8, and the water is sprayed out through the nozzle 10 to form a water mist. Simultaneously, the drive mechanism rotates the annular water pipe 9 and the annular air pipe 15, and the rotation of the annular air pipe 15 causes the air outlet 16 to rotate, thereby allowing the high-temperature water vapor to cover a wider and more uniform area. This avoids the high-temperature water vapor being sprayed out through the air outlet 16 and only impacting a fixed point, resulting in uneven distribution of high-temperature water vapor and affecting deoxygenation efficiency. At the same time, the rotation of the annular water pipe 9 causes the nozzle 10 to rotate, thereby ensuring that the water mist sprayed by the nozzle 10 can be well diffused into the entire deoxygenation tank 1. The deoxygenated water is discharged through the drain pipe 3.

[0017] Example 2 Based on Example 1, referring to Figure 1 The driving mechanism includes a rotating rod 17, which is horizontally rotatable between the annular water pipe 9 and the annular air pipe 15, and has a conical transmission gear 18 sleeved on its outer side. The bottom end of the water inlet pipe 5 is fixedly connected to a vertically arranged upper rotating rod 19, and the end of the upper rotating rod 19 is provided with an upper conical gear 20 that meshes with the conical transmission gear 18. The top end of the air inlet pipe 11 is fixedly connected to a vertically arranged lower rotating rod 21, and the end of the lower rotating rod 21 is provided with a lower conical gear 22 that meshes with the conical transmission gear 18. The outer side of the deaerator tank 1 is provided with a motor 23, and the output shaft of the motor 23 is connected to one end of the rotating rod 17 for transmission.

[0018] In this embodiment, the motor 23 drives the rotating rod 17 to rotate, which in turn drives the bevel transmission gear 18 to rotate. The bevel transmission gear 18 meshes with the upper bevel gear 20 and the lower bevel gear 22, thereby driving the lower bevel gear 22 and the upper bevel gear 20 to rotate. The lower bevel gear 22 and the upper bevel gear 20 drive the upper rotating rod 19 and the lower rotating rod 21 to rotate, respectively. The upper rotating rod 19 and the lower rotating rod 21 drive the water inlet pipe 5 and the air inlet pipe 11 to rotate in opposite directions, ultimately driving the annular air pipe 15 and the annular water pipe 9 to rotate.

[0019] As a preferred embodiment, refer to Figure 1 The upper rotating rod 19 and the lower rotating rod 21 are connected to the outer sides of the plate 24 arranged in a ring array. Specifically, by setting the plate 24, the water that accumulates during the fall can be broken into smaller droplets, which is beneficial to the uniform heating of the water.

[0020] As a preferred embodiment, refer to Figure 1Inside the deaerator tank 1, between the flap 24 and the annular air pipe 15, there is a retention net 25, and the lower rotating rod 21 rotates through the retention net 25. Specifically, the water mist passes through the retention net 25, which further prolongs the time in the deaerator tank 1, allowing the water to be fully heated for deaeration.

[0021] Example 3 Based on Example 1, referring to Figure 1 A scraper 26 is provided on the outer side of the air intake pipe 11, and the bottom side of the scraper 26 slides against the inner bottom wall of the deaerator 1.

[0022] In this embodiment, by setting scraper 26, the water collected at the bottom of the deaerator tank 1 can be scraped to make it flow, thereby ensuring that the water is discharged through the drain pipe 3.

[0023] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
