Description

Technical Field

[0001] The present invention relates to the technical field of water drainage devices, in particular to an energy-saving air-cooled silent water drainage device. Background Art

[0002] The steam traps currently widely used in the market produce varying degrees of entrained steam, flash steam from high-temperature water, and noise from the high-speed discharge of steam / liquid two-phase fluids during the drainage process. These traps cannot fully achieve the effect of steam blocking and water drainage, thus causing environmental problems such as noise nuisance, white steam diffusion, and high-temperature radiation. Summary of the Invention

[0003] In response to the above problems, the present invention provides an energy-saving air-cooled silent drainage device, which gradually cools and reduces the pressure of the drain carrying high-temperature and high-pressure steam through a drainage chamber until the flash steam is eliminated and all the drain is converted into saturated water. The saturated water is then cooled by external air or cold water, while the flow rate of the saturated water is slowed down, effectively solving the problems of noise emissions, high-temperature radiation, and white steam diffusion in the drainage process, and playing a significant role in environmental protection and urban beautification.

[0005] Pipeline components;

[0006] and air-cooled drain components;

[0007] The pipeline assembly and the air-cooled hydrophobic assembly are connected through a hydrophobic connecting pipe, and the hydrophobic connecting pipe is connected to the air-cooled hydrophobic assembly through a large-to-small joint; the air-cooled hydrophobic assembly includes a drainage pipe and a plurality of drainage chambers, and a terminal buffer chamber, the terminal of the hydrophobic connecting pipe is connected to the drainage pipe, and a plurality of drainage chambers are arranged in sequence behind the drainage pipe, and the plurality of drainage chambers are arranged in sequence, and adjacent drainage chambers are separated by partitions, and a terminal buffer chamber is provided behind the terminal drainage chamber;

[0008] The front drainage chamber is connected to the inner cavity of the adjacent rear drainage chamber through a pressure regulating tube provided with an upward convexity, and the pressure regulating tube passes through a connecting tube provided with a bypass, and the lower outlet end of the connecting tube is connected to the inner cavity of the adjacent rear drainage chamber;

[0009] The drainage chamber at the very end is provided with an upwardly convex pressure regulating tube, which is connected to the inner cavity of the adjacent rear end buffer chamber through a connecting tube provided with a bypass.

[0010] A float regulating tube is provided in each of the pressure regulating tubes, the upper end of the float regulating tube is connected to the inner cavity of the pressure regulating tube, and the lower end of the float regulating tube is connected to the drainage chamber below. The float regulating tube is a hollow tube, and an adjusting rod is installed in the float regulating tube. A first float is installed at the upper end of the adjusting rod, and a second float is installed at the lower end of the adjusting rod. The diameters of the first float and the second float are both larger than the inner diameter of the float regulating tube, and both are arranged in the outer area of the float regulating tube.

[0011] It is further characterized by:

[0012] The buoyancy of the second float ball when floating upward ensures that the first float ball, the second float ball and the adjustment rod float upward together;

[0013] The ends of the pipe path of the most terminal drainage chamber are connected to the venturi tube and the large diameter pipe respectively;

[0014] All drainage chambers are arranged horizontally and have the same inner diameter, ensuring quick and efficient assembly;

When the front drainage chamber opens the channel of the float ball regulating tube of the front drainage chamber under the action of water buoyancy and the pressure difference of the drainage chamber, water flows from the front drainage chamber to the rear drainage chamber until the buoyancy force can no longer open the channel of the corresponding float ball regulating tube, and then part of the water in the front drainage chamber flows into the rear drainage chamber. The temperature and pressure are reduced until the saturated water finally enters the final drainage chamber and is discharged outside the venturi box.

The drainage water carrying high-temperature and high-pressure steam is cooled and depressurized step by step through the drainage chamber until the flash steam is eliminated and all the drainage water is converted into saturated water. The saturated water is then cooled by external air or cold water, and the saturated water flow rate is slowed down at the same time, effectively solving the problems of noise emission, high-temperature radiation and white steam diffusion in the drainage process, which plays a significant role in environmental protection and urban beautification.

[0026] An energy-saving air-cooled silent water discharge device, see Figure 1-Figure 3 , which includes a pipe assembly 100 and an air-cooled drain assembly 200;

[0027] The pipe assembly 100 and the air-cooled drain assembly 200 are connected through the drain connecting pipe 6, and the drain connecting pipe 6 and the air-cooled drain assembly 200 are connected through the large-to-small joint 9; the air-cooled drain assembly 200 includes a drainage pipe 10 and a plurality of drainage chambers 11, and an end buffer chamber 19.

The diameters of the first float 15 and the second float 12 are both larger than the inner diameter of the float regulating tube 13, and are both located in the outer area of the float regulating tube 13.

[0031] In a specific implementation, the buoyancy of the second float 12 when floating up ensures that the first float 15, the second float 12 and the adjustment rod 14 float up together;

[0032] The ends of the pipe path of the last drainage chamber 19 are connected to a venturi tube and a large diameter pipe (not shown in the figure, belonging to conventional pipe connection technology);

[0033] All drainage chambers 11 are arranged horizontally and have the same inner diameter, ensuring quick and efficient assembly;

[0034] The connecting pipe 17 includes a horizontal section and a downward curved section. The inlet end of the horizontal section is connected to the bypass port of the pressure regulating pipe 16, the outlet end of the horizontal section is connected to the upper end of the downward curved section, and the lower section of the downward curved section is connected to the upper front end of the inner cavity of the adjacent rear drainage chamber 11.

[0035] The piping system 100 includes a steam pipe 1, a water collecting hopper 2, and a drain pipe 3. The steam pipe 1 is arranged horizontally. The water collecting hopper 2 is installed in the opening of the outer wall below the steam pipe 1. The outer ring wall opening of the water collecting hopper 2 is connected to the drain pipe 3. A drain valve 4 and a drain secondary valve 5 are installed at intervals on the vertical section of the drain pipe 3. The drain pipe between the drain valve 4 and the drain secondary valve 5 is provided with a bypass opening, and a drain connecting pipe 6 is installed in the bypass opening.

[0036] The drain connecting pipe 6 is arranged horizontally. A drain primary valve 7 and a drain secondary valve 8 are installed horizontally at intervals on the drain connecting pipe 6 , and a large-to-small joint 9 is connected to the end of the drain connecting pipe 6 .

[0037] During specific implementation: the number of drainage chambers 11 is five, which correspond to drainage chamber 11-1, drainage chamber 11-2, drainage chamber 11-3, drainage chamber 11-4, and drainage chamber 11-5 respectively; the steam pressure in the steam pipe 1 is 0.6MPa; the diameter of the drain straight pipe 3 is DN80, the diameter of the drain connecting pipe 6 is DN25-50, the diameter of the drainage chamber 11 is φ89mm, the wall thickness is 6mm, the diameter of the pressure regulating pipe 16 is φ57mm, the wall thickness is 4mm, the diameter of the float regulating pipe 13 and the connecting pipe 17 is φ32mm, the wall thickness is 3mm, the thickness of the partition 18 is 10mm, the diameter of the first float ball is 40mm, the diameter of the second float ball is 50mm, the air-cooled drain assembly 200 is made of stainless steel or seamless steel pipe, the material of the drain connecting pipe 6 is seamless steel pipe, and the end buffer chamber 19 is connected to the Venturi tube and the φ219 pipe.

[0038] Its working principle is as follows: the drain discharged from the pipe assembly is connected to the drainage pipe through the large-to-small joint, and then the drain is drained one by one into the drainage chambers arranged in sequence. Under the initial action of gravity, the first float and the second float block the upper port of the float adjustment tube. When the front drainage chamber opens the channel of the float adjustment tube of the front drainage chamber under the action of water buoyancy and the pressure difference of the drainage chamber, water flows from the front drainage chamber to the rear drainage chamber until the buoyancy cannot open the channel of the corresponding float adjustment tube. After that, part of the water in the front drainage chamber flows into the rear drainage chamber, cools down and reduces pressure, until the final saturated water enters the last drainage chamber and is drained outside the Venturi tube box. External cooling air or cold water is inhaled during the drainage process. The specific working principle of the specific embodiment is as follows: the first step is pressure reduction / temperature reduction discharge. Figure 3 :

[0039] After being collected in the hopper, the condensed water flows into drainage chamber 1. Under the dual effects of water buoyancy and a 0.1 MPa pressure differential, the double floats G1 and G1' overcome their own gravity and automatically open channel A, connecting drainage chambers 1 and 2. The saturated water changes from the parameters of 0.6 MPa(g) and 164°C in drainage chamber 1 to the parameters of 0.5 MPa(g) and 158°C in drainage chamber 2. As the pressure in drainage chamber 2 rises and the water level in drainage chamber 1 drops, channel A is automatically closed under the action of gravity of the double floats G1 and G1'.

[0040] As the saturated water partially enters drainage chamber 2, accompanied by flash steam, the pressure in drainage chamber 2 slowly rises to 0.5 MPa(g). Channel A is automatically closed, and the double floats G2 and G2' are lifted to open channel B, connecting drainage chambers 2 and 3. Saturated water enters drainage chamber 3, and the parameters drop to 0.4 MPa(g) and 151°C. Similarly, channel B is closed, the double floats G3 and G3' are lifted, and channel C is opened, allowing saturated water to enter drainage chamber 4, and the parameters drop to 0.3 MPa(g) and 142.9°C. Channel C is closed, the double floats G4 and G4' are lifted, and channel D is opened, allowing saturated water to enter drainage chamber 5, and the parameters drop to 0.2 MPa(g) and 132.9°C. Channel D is closed, the double floats G5 and G5' are lifted to open channel E, allowing saturated water to enter the terminal buffer chamber 6, and the parameters drop to 0.1 MPa(g) and 119.6°C.

[0041] The second step is noise reduction and temperature reduction: Saturated water at 0.1 MPa(g) and 119.6°C is discharged through a Venturi tube, drawing in cold air / water from the outside, cooling the saturated water while slowing its flow rate. This discharge reduces noise and temperature. As the mixed, cooled, and desuperheated water spirals down the tube wall, it continuously dissipates heat, further cooling it to the desired temperature.

[0042] The beneficial effects are as follows: first, the steam entrainment is limited to the maximum extent; second, the steam is flashed out to the maximum extent and the entry into the next stage is limited; third, the heat flashed out when the saturated water drops from 160 degrees to 119 degrees is retained in the drain system, facilitating the subsequent energy utilization.
