Description

Technical Field

[0001] This utility model belongs to the field of hydrophobic expansion technology, and relates to a hydrophobic expansion container, particularly a hydrophobic expansion container that utilizes industrial water spray cooling. Background Technology

[0002] A condensate expander is an instrument used to separate steam and condensate. It expands and depressurizes the condensate in a pressurized condensate line, separating the steam and condensate. The steam is then introduced into a heat exchanger or deaerator to fully utilize its thermal energy, while the condensate is periodically introduced into a condensate tank and fed into the water supply system.

[0003] A search revealed a Chinese patent document disclosing a hydrophobic expansion container [Application No.: 202322737972.6; Publication No.: CN 220770794 U]. This hydrophobic expansion container, relating to the field of hydrophobic expansion technology, includes a housing. A second cover plate is connected to the top of the housing. A second drainage pipe is fixedly connected inside the second cover plate. A motor is fixedly connected inside the second cover plate, and a cooling pipe is fixedly connected to the output end of the motor. The beneficial effects of this invention are: by opening several cooling outlets on the outside of the cooling pipe, the drainage inside the first drainage pipe is cooled; by starting the motor, the cooling pipe rotates, raising the cooling range of the first drainage pipe; by starting the electric telescopic rod, a slider moves; and by the slider moving, a first limiting block, a second connecting block, and a second limiting block move, limiting the water vapor generated during cooling and drainage to prevent excessive water vapor loss.

[0004] Although the patent limits the water vapor generated during cooling and condensation to prevent excessive loss, the heat conduction between the cooling liquid and the condensate inside the pipe requires the pipe as a medium, which affects the heat dissipation and cooling effect. Furthermore, the fluidity of the condensate inside the pipe further affects the cooling effect on high-temperature condensate, resulting in poor cooling performance. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a hydrophobic expansion container that utilizes industrial water spraying for cooling. The technical problem this invention aims to solve is: how to achieve the cooling of high-temperature hydrophobic water using industrial water to reduce energy consumption, and how to achieve rapid cooling of high-temperature hydrophobic water through multi-stage spraying.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A hydrophobic expansion tank for cooling by industrial water spray includes a hydrophobic expansion tank and a spray cooling tank fixed at the bottom of the hydrophobic expansion tank. Multiple cooling tubes are fixed inside the hydrophobic expansion tank, each cooling tube is wound with a hydrophobic expansion tube, and multiple steam valves are arranged and fixed on the top surface of each hydrophobic expansion tube. A hydrophobic interface is fixed on the top surface of the hydrophobic expansion tank, one end of which is fixedly connected to the multiple cooling tubes. The bottom end of each hydrophobic expansion tube is connected to the interior of the spray cooling tube. A multi-stage spray cooling assembly is installed inside the spray cooling tube. An industrial water interface is fixed on the top surface of the hydrophobic expansion tank, one end of which is fixedly connected to the multiple cooling tubes.

[0008] The working principle of this invention is as follows: When the high-temperature condensate flows into the condensate expansion tube, the pressure suddenly drops, and the vaporization point of the water also decreases. Some of the water will vaporize into steam, while the unvaporized high-temperature water will be cooled through the cooling tube. Since multiple condensate expansion tubes are wound around the corresponding cooling tubes, the contact area between the condensate expansion tubes and the cooling tubes is increased, improving the cooling effect of the cooling tubes. The high-temperature water after simple cooling then flows into the spray cooling tank for further cooling through the multi-stage spray cooling components, improving the cooling effect and efficiency.

[0009] The multi-stage spray cooling assembly includes a water spray plate fixed to the inner wall of the spray cooling tank, an annular spray frame one fixed to the inner wall of the spray cooling tank, and an annular spray frame two fixed to the inner wall of the spray cooling tank. The bottom ends of multiple cooling pipes are embedded in the inner wall of the spray cooling tank, and the bottom ends of multiple cooling pipes are all connected to the interior of the annular spray frame one. Multiple spray nozzles one are arranged and fixed on the inner ring surface of the annular spray frame one, and multiple spray nozzles two are arranged and fixed on the inner ring surface of the annular spray frame two. An industrial water interface two is fixed on the spray cooling tank, and the industrial water interface two is connected to each spray nozzle two.

[0010] With the above structure, the flow of high-temperature water can be guided by the water spray plate to ensure even distribution. At this time, multiple spray nozzles spray out industrial water curtains, which fully contact the distributed high-temperature water to improve the cooling effect. To further improve the cooling effect, multiple spray nozzles spray the high-temperature water a second time to achieve rapid cooling.

[0011] Both industrial water inlet one and industrial water inlet two are fixed with flow regulating valves.

[0012] With the above structure, the flow regulating valve can be connected to a remote computer DCS system to remotely control the entry of industrial water and further control the cooling status.

[0013] Multiple temperature monitors are fixed inside the hydrophobic expansion tank and the spray cooling tank, arranged along their height.

[0014] With the above structure, the temperature of different height areas of the overall structure can be monitored by multiple temperature monitors, making it convenient for personnel to understand the temperature conditions of each area and improving the operability of personnel.

[0015] The top surface of the hydrophobic expansion tank is fixed with a steam interface, and the bottom of the spray cooling tank is fixed with a recovery interface.

[0016] With the above structure, the steam generated in the condensate expansion tank can be recovered by connecting to an external steam pipe through a steam interface, and the cooled condensate can be recovered by connecting to an external condensate pipe through a recovery interface.

[0017] Compared with existing technologies, this hydrophobic expansion tank utilizing industrial water spray cooling has the following advantages:

[0018] 1. By winding multiple hydrophobic expansion tubes around the corresponding cooling tubes, the contact area between the hydrophobic expansion tubes and the cooling tubes is increased, thereby improving the cooling effect of the cooling tubes.

[0019] 2. The cooled high-temperature water then flows into the spray cooling tank for further cooling through a multi-stage spray cooling component, improving the cooling effect and efficiency, and achieving rapid cooling. Attached Figure Description

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figures 1-3As shown, a hydrophobic expansion tank for cooling by industrial water spray includes a hydrophobic expansion tank 1 and a spray cooling tank 2 fixed at the bottom of the hydrophobic expansion tank 1. Multiple cooling pipes 3 are fixed inside the hydrophobic expansion tank 1. A hydrophobic expansion pipe 4 is wound around each cooling pipe 3. Multiple steam valves 5 are arranged and fixed on the top surface of each hydrophobic expansion pipe 4. A hydrophobic interface 6 is fixed on the top surface of the hydrophobic expansion tank 1. One end of the hydrophobic interface 6 is fixedly connected to the multiple cooling pipes 3. The bottom end of each hydrophobic expansion pipe 4 is connected to the inside of the spray cooling pipe 3. A multi-stage spray cooling component is installed inside the spray cooling pipe 3. An industrial water interface 7 is fixed on the top surface of the hydrophobic expansion tank 1. One end of the industrial water interface 7 is fixedly connected to the multiple cooling pipes 3.

[0026] When the high-temperature water flows into the condensate expansion pipe 4, the pressure suddenly drops, and the vaporization point of the water also decreases. Some of the water will vaporize into steam, while the unvaporized high-temperature water will be cooled through the cooling pipe 3. Since multiple condensate expansion pipes 4 are wound around the corresponding cooling pipes 3, the contact area between the condensate expansion pipes 4 and the cooling pipes 3 is increased, improving the cooling effect of the cooling pipes 3. After simple cooling, the high-temperature water flows into the spray cooling tank 2 for further cooling through the multi-stage spray cooling components, improving the cooling effect and efficiency.

[0027] The multi-stage spray cooling assembly includes a water spray plate 8 fixed to the inner wall of the spray cooling tank 2, an annular spray frame 9 fixed to the inner wall of the spray cooling tank 2, and an annular spray frame 10 fixed to the inner wall of the spray cooling tank 2. The bottom ends of multiple cooling pipes 3 are embedded in the inner wall of the spray cooling tank 2, and the bottom ends of multiple cooling pipes 3 are all connected to the interior of the annular spray frame 9. Multiple spray nozzles 11 are arranged and fixed on the inner ring surface of the annular spray frame 9, and multiple spray nozzles 22 are arranged and fixed on the inner ring surface of the annular spray frame 10. An industrial water interface 23 is fixed on the spray cooling tank 2, and the industrial water interface 213 is connected to each spray nozzle 22.

[0028] With the above structure, the flow of high-temperature water can be guided by the water spray plate 8 to ensure even distribution. At this time, multiple spray nozzles 11 spray out industrial water curtains to fully contact the distributed high-temperature water, thereby improving the cooling effect. To further improve the cooling effect, multiple spray nozzles 12 spray the high-temperature water a second time to achieve rapid cooling.

[0029] Both industrial water inlet 17 and industrial water inlet 213 are equipped with flow regulating valves.

[0030] With the above structure, the flow regulating valve can be connected to a remote computer DCS system to remotely control the entry of industrial water and further control the cooling status.

[0031] Multiple temperature monitors 15 are fixed inside the hydrophobic expansion tank 1 and the spray cooling tank 2, arranged along their height.

[0032] With the above structure, the temperature of different height areas of the overall structure can be monitored by multiple temperature monitors 15, which makes it convenient for personnel to understand the temperature conditions of each area and improves the operability of personnel.

[0033] A steam port 14 is fixed on the top surface of the hydrophobic expansion tank 1, and a recovery port 16 is fixed on the bottom of the spray cooling tank 2.

[0034] With the above structure, the steam generated in the condensate expansion tank 1 can be recovered by connecting to an external steam pipe through the steam interface 14, and the condensate can be recovered by connecting to an external condensate pipe through the recovery interface 16.

[0035] The working principle of this utility model is as follows: When the high-temperature condensate flows into the condensate expansion pipe 4, the pressure suddenly drops, and the vaporization point of the water also decreases. Some of the water vaporizes into steam, which is discharged into the condensate expansion tank 1 from the steam valve 5 on the top surface of the condensate expansion pipe 4. The steam generated in the condensate expansion tank 1 is recovered through the external steam pipe connected to the steam structure. The unvaporized high-temperature water is cooled by the cooling pipe 3. Since multiple condensate expansion pipes 4 are wound around the corresponding cooling pipes 3, the contact area between the condensate expansion pipes 4 and the cooling pipes 3 is increased, improving the cooling effect of the cooling pipes 3. The high-temperature water after simple cooling flows into the spray cooling tank 2. The flow of the high-temperature water is guided by the water spray plate 8, so that it is evenly distributed. At this time, multiple spray nozzles 11 spray out industrial water curtains, which fully contact the distributed high-temperature water to improve the cooling effect. To further improve the cooling effect, multiple spray nozzles 12 spray the high-temperature water a second time to achieve rapid cooling.

[0036] In summary, when the high-temperature condensate flows into the condensate expansion pipe 4, the pressure suddenly drops, and the vaporization point of the water also decreases. Some of the water will vaporize into steam, while the unvaporized high-temperature water will be cooled through the cooling pipe 3. Since multiple condensate expansion pipes 4 are wound around the corresponding cooling pipes 3, the contact area between the condensate expansion pipes 4 and the cooling pipes 3 is increased, improving the cooling effect of the cooling pipes 3. The high-temperature water after simple cooling then flows into the spray cooling tank 2 for further cooling through the multi-stage spray cooling components, improving the cooling effect and efficiency.
