The regulating assembly includes a regulating box 4, the regulating box 4 is installed on the top of the regulating pipe 2, and the inner side wall of the regulating box 4 is symmetrically provided with a slide 5, the top of the regulating box 4 is penetrated by a screw 6, the top of the screw 6 is provided with a handle 7, the bottom end of the screw 6 is movably connected with a stopper 8, and the two sides of the stopper 8 are symmetrically provided with a slide bar 9, and the slide bar 9 is slidably connected with the slide 5. The flash tank body 1 provides an installation connection position for the regulating pipe 2. The regulating pipe 2 provides a connection position for the water inlet pipe 3. The regulating pipe 2 provides an installation position for the regulating assembly. The regulating pipe 2 provides an installation connection position for the regulating box 4. The regulating box 4 provides an opening position for the slide 5. The regulating box 4 provides an installation position for the screw 6. The screw 6 provides an installation position for the turning handle 7 and the stopper 8. The stopper 8 provides an installation position for the slide bar 9. The slide bar 9 and the slide groove 5 cooperate with each other to limit the movement trajectory of the stopper 8. When high-temperature water passes through the water inlet pipe 3, the staff can turn the turning handle 7. The rotation of the turning handle 7 drives the screw 6 to rotate together. The rotation of the screw 6 causes the stopper 8 to rise and fall under the restriction of the slide bar 9 and the slide groove 5. The rise and fall of the stopper 8 changes the size of the cross-sectional area of ​​the water inlet pipe, thereby changing the flow rate of the high-temperature water inlet, and preventing the high-temperature water from entering the flash tank. The impact force of the water pressure is too large, which makes the flash tank easy to be damaged.

[0025] Embodiment 2: Figure 1-Figure 4As shown, an energy dissipation flash evaporator 10 is installed on the inner wall of the flash tank body 1, and the energy dissipation flash evaporator 10 and the water inlet pipe 3 are located at the same horizontal plane. A drain pipe 11 is connected to the bottom center of the flash tank body 1, and a drain regulating valve 12 is installed on the outside of the drain pipe 11. A steam discharge pipe 13 is connected to the top center of the flash tank body 1, and a labyrinth steam-water separator 14 is installed on the upper inner wall of the flash tank body 1, and the labyrinth steam-water separator 14 is located below the steam discharge pipe 13. A mounting support 15 is symmetrically installed at the bottom of the flash tank body 1. The flash tank body 1 provides an installation position for the energy dissipation flash evaporator 10. The flash tank body 1 provides a connection position for the drain pipe 11. The drain pipe 11 provides an installation and connection position for the drain regulating valve 12.

High-temperature water enters the interior of the flash tank body 1 from the water inlet pipe 3 and the regulating pipe 2, passes through the energy dissipation flash evaporator 10, rotates and stays in the energy dissipation flash evaporator 10, and enters the interior of the flash tank. After the high-pressure saturated water enters the relatively low-pressure container, due to the sudden drop in pressure, the saturated water flashes into saturated steam and saturated water under a part of the container pressure. The saturated steam passes through the labyrinth steam-water separator 14 to separate saturated steam with a certain dryness, and finally the saturated steam flows out from the steam exhaust pipe 13.

[0026] Embodiment 3: A safety valve 16 is installed on the other side of the flash tank body 1, and a liquid level sensor 17 is installed on the other side of the flash tank body 1 through double pipes. The flash tank body 1 provides an installation position for the safety valve 16. The flash tank body 1 provides an installation position for the liquid level sensor 17. The liquid level sensor 17 is used to detect the water level in the flash tank body 1. The flash steam pressure can be automatically adjusted by the regulating valve connected to the remote temperature and flash steam discharge pipe 13, and the liquid level in the flash tank can be automatically adjusted by the remote liquid level sensor 17 and the drainage regulating valve 12 outside the drain pipe 11.

[0027] A connecting pipe 18 is installed on the top of the flash tank body 1, and an externally threaded pipe 19 is connected to the top of the connecting pipe 18. A sealing gasket 20 is installed on the top of the connecting pipe 18, and the sealing gasket 20 is located on the outside of the externally threaded pipe 19, and an internally threaded pipe 21 is installed on the outside of the externally threaded pipe 19, and a pressure gauge 22 is connected to the top of the internally threaded pipe 21. The flash tank body 1 provides a connection position for the connecting pipe 18. The connecting pipe 18 provides a connection position for the externally threaded pipe 19 and provides an installation position for the sealing gasket 20.

The externally threaded pipe 19 provides an installation position for the internally threaded pipe 21. The internally threaded pipe 21 provides an installation position for the pressure gauge 22. The pressure gauge 22 is used to detect the pressure inside the flash tank body 1. The safety valve 16 is used to protect the safety of the system. When the pressure exceeds the set pressure of the safety valve 16, the safety valve 16 will automatically open to release the pressure, thereby reducing the pressure in the pressure vessel and ensuring the normal operation of the equipment. When assembling the pressure gauge 22 with the flash tank, place the internal threaded tube 21 on the outside of the external threaded tube 19 so that the threads are engaged, and then rotate the internal threaded tube 21 until the bottom end of the internal threaded tube 21 contacts the sealing gasket 20 at the top of the connecting tube 18. This makes it easy for the staff to install the pressure gauge 22 and facilitates the installer to assemble the pressure gauge 22 onto the flash tank.

[0028] Working principle: Before using the flash tank waste heat utilization device, you should first check whether there are any problems that affect the use of the flash tank waste heat utilization device. First, place the flash tank waste heat utilization device in the position where it needs to be used. When high-temperature water passes through the water inlet pipe 3, the staff can turn the handle 7. The rotation of the handle 7 drives the screw 6 to rotate together. The rotation of the screw 6 causes the block 8 to rise and fall under the restriction of the slide bar 9 and the slide groove 5. The rise and fall of the block 8 changes the size of the cross-sectional area of ​​the water inlet pipe, thereby changing the flow rate of the high-temperature water inlet, and preventing the flash tank from being easily damaged by the excessive impact of the water pressure when the high-temperature water enters the flash tank. When assembling the pressure gauge 22 with the flash tank, place the internal threaded tube 21 on the outside of the external threaded tube 19 to engage the threads, and then rotate the internal threaded tube 21 until the bottom end of the internal threaded tube 21 contacts the sealing gasket 20 at the top of the connecting pipe 18. This is convenient for the staff to install the pressure gauge 22 and convenient for the installer to assemble the pressure gauge 22 to the flash tank. High-temperature water enters the interior of the flash tank body 1 from the water inlet pipe 3 and the regulating pipe 2, passes through the energy dissipation flash evaporator 10, rotates and stays in the energy dissipation flash evaporator 10, and enters the interior of the flash tank. After the high-pressure saturated water enters the relatively low-pressure container, due to the sudden drop in pressure, the saturated water flashes into saturated steam and saturated water under a part of the container pressure. The saturated steam passes through the labyrinth steam-water separator 14 to separate saturated steam with a certain dryness, and finally the saturated steam flows out from the steam discharge pipe 13. The flash steam pressure can be automatically adjusted by the regulating valve connected to the remote temperature and the flash steam discharge pipe 13, and the liquid level in the flash tank can be automatically adjusted by the remote liquid level sensor 17 and the drainage regulating valve 12 outside the drainage pipe 11.
