Description

Technical Field

[0001] This utility model relates to the field of waste steam recovery technology, and in particular to a high-performance waste steam recovery device for thermal deaerators. Background Technology

[0002] The background of exhaust steam recovery technology from thermal deaerators can be traced back to the increasing emphasis on energy efficiency and water quality management in industrial production processes. With the global energy crisis and growing environmental awareness, enterprises are increasingly focusing on reducing energy consumption and emissions while pursuing economic benefits. Against this backdrop, exhaust steam recovery technology from thermal deaerators has emerged as an important means to improve boiler system efficiency. In traditional boiler systems, dissolved oxygen in feedwater can cause corrosion and shorten equipment lifespan; therefore, a thermal deaerator is needed to remove oxygen from the water. Simultaneously, boilers generate exhaust steam during operation. Although this exhaust steam has lower temperature and pressure, it still contains considerable heat. If not utilized, this exhaust steam will be released into the environment, resulting in a waste of thermal energy.

[0003] When existing thermal deaerators generate exhaust steam during operation, they usually discharge it directly, resulting in a large amount of exhaust steam waste. Furthermore, they cannot collect the liquid in the exhaust steam, leading to low utilization of exhaust steam in existing recovery devices and a significant waste of heat along the way. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-performance thermal deaerator exhaust steam recovery device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-performance thermal deaerator exhaust steam recovery device includes a deaerator body. The bottom outer wall of the deaerator body is welded with equally spaced support legs, and a gas guide pipe is provided on one side of the front of the deaerator body. A solenoid valve is fixedly connected to one side of the gas guide pipe. Four L-shaped brackets are fixedly connected to the outer wall of the deaerator body near the bottom of the gas guide pipe, and a collection box is snapped into the L-shaped brackets.

[0007] The L-shaped bracket has T-shaped pipes welded to its top two sides, and the two ends of the T-shaped pipes are connected to the two sides of the collection box through U-shaped pipes. The collection box has a reciprocating mechanism inside, and an adsorption net is fixedly connected to one side of the bottom of the reciprocating mechanism.

[0008] As a further embodiment of this utility model: the reciprocating mechanism includes a rack plate, an incomplete gear, a drive tooth, a drive fan, a rotating shaft one and a rotating shaft two, and the rotating shaft one and the rotating shaft two are respectively rotatably connected to the inner wall of the back of the collection box. The drive fan is threadedly connected to the circumference of the rotating shaft one, and the drive tooth is threadedly connected to the end circumference of the rotating shaft one, and the circumference of the drive tooth has only two sets of teeth.

[0009] As a further embodiment of this utility model: the incomplete gear is threadedly connected to the circumference of the rotating shaft two, the incomplete gear meshes with the drive gear, and one of the U-shaped tubes is provided with an air blowing pipe at the tail end of the collection box, and the end of the air blowing pipe points to the side of the drive fan.

[0010] As a further embodiment of this utility model: a guide rail is fixedly connected to the back of the collection box, the back of the three adsorption nets are slidably fitted with the guide rail, and a rack plate is fixedly connected to the top of the three adsorption nets, with the rack plate meshing with the incomplete gear and the drive gear.

[0011] As a further improvement of this utility model: the inner wall of the collection box near the incomplete gear is fixedly connected with absorbent cotton by a support plate.

[0012] As a further improvement of this utility model: another U-shaped tube has an L-shaped air tube at its tail end that passes through the collection box, with the bottom end of the L-shaped air tube facing directly above the absorbent cotton.

[0013] As a further improvement of this utility model: a conical guide block is fixedly connected to the inner wall of the three-way pipe near the bottom of the air guide pipe, and a guide hole is provided between the bottom of the air guide pipe and the conical guide block.

[0014] Compared with the prior art, this utility model provides a high-performance thermal deaerator exhaust steam recovery device, which has the following beneficial effects:

[0015] This high-performance thermal deaerator exhaust steam recovery device, equipped with a rack plate, incomplete gear, drive gear, drive fan, rotating shaft one, rotating shaft two, air blowing pipe and washing cotton, can not only recover moisture from exhaust steam, but also filter and adsorb water collected in the collection tank, effectively removing impurities from the water, ensuring the cleanliness of the recovered water, and achieving environmental protection.

[0016] This high-performance thermal deaerator exhaust steam recovery device features a conical guide block at the connection point of the two pipes. When the exhaust steam in the guide pipe enters the three-way pipe downwards, the flow cross-section is narrowed, which causes the exhaust steam to pass through the guide hole quickly, increasing the flow speed of the exhaust steam. This allows the exhaust steam to quickly enter the collection box through the U-shaped pipe, thus driving the reciprocating mechanism to work rapidly.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] A high-performance thermal deaerator exhaust steam recovery device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a deaerator body 2. The bottom outer wall of the deaerator body 2 is welded with equally spaced support legs 1. A gas guide pipe 5 is threadedly connected to one side of the front of the deaerator body 2. A solenoid valve 6 is fixedly connected to one side of the gas guide pipe 5. Four L-shaped brackets 3 are fixedly connected to the outer wall of the deaerator body 2 near the bottom of the gas guide pipe 5. A collection box 4 is snapped into the L-shaped brackets 3.

[0028] The top two sides of the L-shaped bracket 3 are welded with T-tubes 8, and the two ends of the T-tubes 8 are connected to the two sides of the collection box 4 through U-shaped tubes 7. The collection box 4 has a reciprocating mechanism 10 inside, and an adsorption net 11 is fixedly connected to one side of the bottom of the reciprocating mechanism 10.

[0029] To make full use of the deaerator exhaust steam, such as Figure 2 , Figure 3 , Figure 4 As shown, the reciprocating mechanism 10 includes a rack plate 1001, an incomplete gear 1002, a drive gear 1003, a drive fan 1004, a first rotating shaft 1005, and a second rotating shaft 1006. The first rotating shaft 1005 and the second rotating shaft 1006 are rotatably connected to the inner wall of the back of the collection box 4. The drive fan 1004 is threaded to the circumference of the first rotating shaft 1005. The drive gear 1003 is threaded to the end circumference of the first rotating shaft 1005. The drive gear 1003 has only two sets of teeth on its circumference.

[0030] The incomplete gear 1002 is threadedly connected to the circumference of the rotating shaft 1006. The incomplete gear 1002 meshes with the drive gear 1003. One of the U-shaped tubes 7 passes through the inside of the collection box 4 and its tail end is threadedly connected to the air blowing pipe 9. The end of the air blowing pipe 9 points to one side of the drive fan 1004.

[0031] A guide rail is fixedly connected to the back of the collection box 4. The back of the three adsorption nets 11 are slidably engaged with the guide rail. The rack plate 1001 is fixedly connected to the top of the three adsorption nets 11. The rack plate 1001 meshes with the incomplete gear 1002 and the drive gear 1003.

[0032] The inner wall of the collection box 4 near the incomplete gear 1002 is fixedly connected to the absorbent cotton 12 by a support plate, and another U-shaped tube 7 passes through the collection box 4 and is connected to the L-shaped air tube 13 by a thread. The bottom end of the L-shaped air tube 13 is directly above the absorbent cotton 12.

[0033] When the exhaust steam from the thermal deaerator enters the three-way pipe 8 through the air guide pipe 5, it enters the collection box 4 through the U-shaped pipes 7 at both ends. The exhaust steam in one of the U-shaped pipes 7 is blown out through the L-shaped air pipe 13 and the water-absorbing cotton 12 absorbs the fixed moisture in it. After the water-absorbing cotton 12 is fully absorbed, it overflows and falls into the collection box 4.

[0034] Meanwhile, the exhaust steam from another U-shaped pipe 7 is blown out through the air blowing pipe 9, and the blown exhaust steam drives the drive fan 1004 to rotate. The rotating drive fan 1004 synchronously drives the drive gear 1003 located on the same axis to rotate. The bottom teeth of the rotating drive gear 1003 drive the rack plate 1001 to move to the left. When the bottom teeth of the drive gear 1003 disengage from the rack plate 1001, the top teeth of the drive gear 1003 contact the incomplete gear 1002 and drive the incomplete gear 1002 to rotate, pulling the rack plate 1001 to move to the right. This realizes that the three sets of adsorption nets 11 at the bottom of the rack plate 1001 complete the reciprocating motion, thereby filtering and adsorbing the water collected in the collection box 4, effectively removing impurities from the water, ensuring the cleanliness of the recycled water, and realizing the environmental protection function.

[0035] To increase the flow rate of exhaust steam, such as Figure 5 As shown, a conical guide block 14 is fixedly connected to the inner wall of the three-way pipe 8 near the bottom of the air guide pipe 5, and a guide hole 15 is provided between the bottom of the air guide pipe 5 and the conical guide block 14.

[0036] When the exhaust steam in the vent pipe 5 enters the three-way pipe 8 downwards, the conical guide block 14 at the connection between the two narrows the flow cross section, causing the exhaust steam to quickly pass through the guide hole 15, increasing the flow speed of the exhaust steam, and causing it to quickly pass through the U-shaped pipe 7 into the collection box 4, prompting the exhaust steam to quickly drive the reciprocating mechanism 10 to work.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
