Description

Technical Field

[0001] This invention relates to the field of power plant wastewater treatment technology, specifically to a rotary energy conversion switch. Background Technology

[0002] For power plants, as major water users and wastewater consumers, their water consumption accounts for 20% of the total industrial water consumption. From multiple perspectives, cascade utilization, concentration and reduction, and water conservation are of great significance for power plants to achieve zero discharge of desulfurization wastewater.

[0003] Currently, a typical 2×600MW thermal power generating unit generates approximately 15 tons of desulfurization wastewater per hour. In the field of zero-discharge treatment of desulfurization wastewater, membrane concentration and volume reduction are the primary technological methods. The total dissolved solids (TDS) of desulfurization wastewater is typically around 50,000 ppm. After multi-stage reverse osmosis membrane concentration, the TDS of the concentrated brine can reach 100,000 ppm. This concentrated brine is then sent to a crystallization evaporation and drying process to ultimately form crystalline salt solids.

[0004] In current projects, desulfurization wastewater is typically pumped into a high-pressure pump at 100% capacity. This pump then further pressurizes the water before it enters the reverse osmosis system. Through the concentration and separation action of the reverse osmosis membrane, a portion of the wastewater is concentrated into high-TDS high-pressure brine. To overcome the osmotic pressure of the high-TDS desulfurization wastewater, the reverse osmosis system requires a very high inlet pressure (50-120 bar). After concentration via reverse osmosis, the pressure of the high-TDS brine often decreases by 1-2 bar. This portion of the high-pressure brine from the reverse osmosis system is then depressurized using valve regulation or flow-limiting orifice plates, typically to below 10 bar. The depressurized, low-pressure brine then enters a crystallization evaporation and drying process. Therefore, the current membrane concentration and reduction process involves significant energy waste.

[0005] Throughout the entire process of desulfurization wastewater treatment, the wastewater needs to be sent to the corresponding treatment process. Therefore, there is an urgent need for a device to quickly send the desulfurization wastewater to the corresponding process. Summary of the Invention

[0039] like Figures 1-11 As shown, the present invention provides a rotary energy conversion switcher, the rotary energy conversion switcher comprising:

[0040] The switching valve body 1 has a switching valve chamber, and a first water inlet 11, a first water outlet 12, a second water inlet 13, a second water outlet 14 and an intermediate water outlet 15 are provided on the wall of the switching valve chamber.

[0041] The switching valve core 2 includes a spindle portion 21 and a left sub-valve core 22, a middle sub-valve core 23 and a right sub-valve core 24 that are fixed sequentially on the spindle portion 21.

The middle sub-valve core 23 is provided with a first middle water channel 230 and a second middle water channel 231. The right sub-valve core 24 is provided with a second right-side water channel 241 and a pair of symmetrically arranged first right-side water channels 242.

A pair of first right side water channels 242 are connected by connecting the fourth sub-cavity 104 to form a fourth flow channel. Adjust the rotation angle of the switching valve core 2 in the switching valve cavity. The middle water port 15 and the first upper water port 11 are connected by connecting the first water channel 20 or the first flow channel. The first upper water port 11 and the first lower water port 12 are connected by connecting the second flow channel. The middle water port 15 and the second upper water port 13 are connected by connecting the second water channel 25 or the third flow channel. The second upper water port 13 and the second lower water port 14 are connected by connecting the fourth flow channel.

[0043] The switching driver 3 is used to drive the switching valve core 2 to rotate within the switching valve chamber.

[0044] The rotary energy conversion switch provided by this invention, such as Figure 1 As shown, a switching valve core 2 is rotatably disposed within the switching valve chamber of the switching valve body 1. The switching valve chamber is divided into a first sub-chamber 101, a second sub-chamber 102, a third sub-chamber 103, and a fourth sub-chamber 104 by the left sub-valve core 22, the middle sub-valve core 23, and the right sub-valve core 24 of the switching valve core 2; Figures 2-3 As shown, a first water channel 20 is formed on the left sub-valve core 22 and the middle sub-valve core 23, and a second water channel 25 is formed on the right sub-valve core 24 and the middle sub-valve core 23. A pair of second left-side water channels 222 formed on the left sub-valve core 22 communicate with the first sub-cavity 101 to form a second flow channel. The pair of second left-side water channels 222 are symmetrically arranged. The first left-side water channel 221 formed on the left sub-valve core 22 and the first middle water channel 230 formed on the middle sub-valve core 23 are connected through the second sub-cavity 102. A first flow channel is formed. A pair of first right-side water channels 242 opened on the right sub-valve core 24 are connected to the fourth sub-cavity 104 to form a fourth flow channel. The pair of first right-side water channels 242 are symmetrically arranged. A second right-side water channel 241 opened on the right sub-valve core 24 and a second intermediate water channel 231 opened on the intermediate sub-valve core 23 are connected through the third sub-cavity 103 to form a third flow channel. When switching between different flow channels, the rotation angle of the switching valve core 2 in the switching valve cavity is adjusted to form different flow channels, such as... Figures 2-6As shown, the flow channels formed when the switching valve core 2 rotates at different angles within the switching valve core are as follows: Figure 2 As shown, when the switching valve core 2 rotates 0 degrees within the switching valve chamber, the intermediate water inlet 15 and the first upper water inlet 11 are connected through the first water channel 20, and the second upper water inlet 13 and the second lower water inlet 14 are connected through the fourth flow channel; after the switching valve core 2 rotates 90 degrees, as... Figure 3 As shown, the first inlet 11 and the first outlet 12 are connected through the second flow channel, and the intermediate outlet 15 and the second inlet 13 are connected through the second water channel 25; after the switching valve core 2 is rotated 180 degrees, as... Figure 4 As shown, the intermediate water inlet 15 is connected to the first water inlet 11 through the first flow channel, and the second water inlet 13 and the second water outlet 14 are connected through the fourth flow channel; after the switching valve core 2 rotates 270 degrees, as... Figure 5 As shown, the first inlet 11 and the first outlet 12 are connected through the second flow channel, and the intermediate outlet 15 and the second inlet 13 are connected through the third flow channel; after the switching valve core 2 rotates 360 degrees, as shown... Figure 6 As shown, the intermediate water inlet 15 and the first water inlet 11 are connected through the first water channel 20, and the second water inlet 13 and the second water outlet 14 are connected through the fourth flow channel. In this way, the switching valve core 2 can switch different flow channels by rotating one revolution in the switching valve chamber, thereby changing the flow direction of the working medium quickly. This solves the problem of needing to quickly change the flow direction of the working medium in the prior art, and can quickly transport desulfurization wastewater to the corresponding process.

[0045] like Figure 1 As shown, the switching driver 3 is a motor, which drives the switching valve core 2 to rotate in the switching valve chamber. The drive shaft of the switching driver 3 and the spindle part 21 of the switching valve core 2 are connected by a coupling 4. A reducer 5 is provided at the output end of the drive shaft of the switching driver 3 to facilitate the adjustment of the rotation speed of the switching valve core 2.

[0046] To balance the pressure within the switching valve chamber, such as Figures 10-11 As shown, a first balancing flow channel 16 is provided on the cavity wall of the switching valve cavity, and the second sub-cavity 102 and the third sub-cavity 103 are connected through the first balancing flow channel 16.

[0047] A second balancing flow channel 17 is provided on the cavity wall of the switching valve chamber, and the first sub-cavity 101 and the fourth sub-cavity 104 are connected through the second balancing flow channel 17.

[0048] like Figures 2-6As shown, the first balancing flow channel 16 connects the second sub-cavities 102 and the third sub-cavities 103 on both sides of the middle sub-valve core 23, balancing the pressure in the second sub-cavities 102 and the third sub-cavities 103, making the force on both sides of the middle sub-valve core 23 uniform. The second balancing flow channel 17 connects the first sub-cavity 101 on the left sub-valve core 22 and the fourth sub-cavity 104 on the right sub-valve core 24, balancing the pressure in the first sub-cavities 101 and the fourth sub-cavities 104, also making the force on the left sub-valve core 22 and the right sub-valve core 24 uniform, ensuring that the switching valve core 2 can rotate stably in the switching valve cavity.

The first left radial water passage 223, the first intermediate radial water passage 232 and the axial water passage 210 are connected to form a first water channel 20.

[0052] A second right radial water hole 243 is provided along the radial direction of the right sub-valve core 24, and a second intermediate radial water hole 233 is provided along the radial direction of the intermediate sub-valve core 23. The second right radial water hole 243 and the second intermediate radial water hole 233 are both connected to the axial water passage hole 210. The second right radial water hole 243, the second intermediate radial water hole 233 and the axial water passage hole 210 are connected to form a second water channel 25.

[0053] The first intermediate radial water hole 232 and the second intermediate radial water hole 233 are arranged perpendicularly to each other.

[0054] The left sub-valve core 22, the middle sub-valve core 23, and the right sub-valve core 24 are sequentially fixed on the spindle portion 21 at intervals. The first water channel 20 is formed by connecting a first left radial water hole 223 opened radially along the left sub-valve core 22, an axial water passage hole 210 opened axially along the spindle portion 21, and a first middle radial water hole 232 opened radially along the middle sub-valve core 23. The opening of the first left radial water hole 223 serves as the first upper water outlet 200 of the first water channel 20, and the opening of the first middle radial water hole 232 serves as the first lower water outlet of the first water channel 20. Water inlet 201, the second water channel 25 is formed by connecting a second right radial water hole 243 opened radially along the right sub-valve core 24, an axial water passage hole 210, and a second intermediate radial water hole 233 opened radially along the intermediate sub-valve core 23. The opening of the second right radial water hole 243 serves as the second upper water inlet 250 of the second water channel 25, and the opening of the second intermediate radial water hole 233 serves as the second lower water inlet 251 of the second water channel 25. Adjusting the rotation angle of the switching valve core 2 in the switching valve chamber, the first upper water inlet 200 is connected to the first upper water inlet 11. The first lower water inlet 201 is connected to the middle water inlet 15, so that the middle water inlet 15 and the first upper water inlet 11 are connected through the first water channel 20. Adjust the rotation angle of the switching valve core 2 in the switching valve chamber. The second upper water inlet 250 is connected to the second upper water inlet 13, and the second lower water inlet 251 is connected to the middle water inlet 15, so that the middle water inlet 15 and the second upper water inlet 13 are connected through the second water channel 25. The first intermediate radial water hole 232 and the second intermediate radial water hole 233 are arranged perpendicularly to each other. The first left radial water hole 223 and the first intermediate radial water hole 233 are connected to the first left radial water hole 223. Water holes 232 are parallel to each other, the first left radial water hole 223 and the second right radial water hole 243 are perpendicular to each other, the second right radial water hole 243 and the second middle radial water hole 233 are parallel to each other, and the valve core 2 can be rotated at different angles to make the middle water port 15 connect to the first upper water port 11 through the first water channel 20 or the middle water port 15 connect to the first upper water port 11 through the first flow channel, or make the middle water port 15 connect to the second upper water port 13 through the second water channel 25 or the middle water port 15 connect to the second upper water port 13 through the third flow channel.

[0055] To ensure the continuous flow of the working medium through the first channel 20, the second channel 25, the first flow channel, and the third flow channel, such as Figures 7-9As shown, overlapping grooves 26 are provided along the circumference of the switching valve core 2 at the water inlet 200 and the water inlet 201 of the first water channel 20, the water inlet 250 and the water inlet 251 of the second water channel 25, the water inlet of the first left side water channel 221 located on the side wall where the left sub-valve core 22 contacts the switching valve cavity, the water inlet of the first middle water channel 230 located on the side wall where the middle sub-valve core 23 contacts the switching valve cavity, the water inlet of the second right side water channel 241 located on the side wall where the right sub-valve core 24 contacts the switching valve cavity, and the water inlet of the second middle water channel 231 located on the side wall where the middle sub-valve core 23 contacts the switching valve cavity.

[0056] Each second left-side waterway 222 has a water outlet on the side wall where the left sub-valve core 22 contacts the switching valve chamber, and each first right-side waterway 242 has a water outlet on the side wall where the right sub-valve core 24 contacts the switching valve chamber, with a buffer groove 27 provided along the circumference of the switching valve core 2.

[0057] like Figure 7 As shown, the overlapping grooves 26 are arranged circumferentially along the switching valve core 2, and each overlapping groove 26 spans the corresponding water inlet. Thus, when the switching valve core 2 rotates, the working fluid flowing through the corresponding water channel or flow path will not be interrupted due to the connection of the overlapping grooves 26. This allows the working fluid from the intermediate water inlet 15 to continuously flow into the switch and out from the first upper water inlet 11 or the second upper water inlet 13, and it has the structural characteristic of simultaneously flowing out from the first upper water inlet 11 and the second upper water inlet 13 at a specific rotation angle, before entering other subsequent equipment. The second left-side water channel 222 is located between the left sub-valve core 22 and the switching valve. The buffer groove 27 at the water inlet on the side wall of the cavity contact is set across the water inlet. The buffer groove 27 at the water inlet on the side wall of the first right side water channel 242 where the right sub-valve core 24 contacts the switching valve cavity is also set across the water inlet. The buffer groove 27 can prevent the working medium flowing through the corresponding flow channel from slowly entering or flowing out of the corresponding flow channel when the switching valve core 2 rotates to switch the water channel or flow channel when a large amount of working medium flows through the rotary energy conversion switcher. This avoids the water channel or flow channel being suddenly connected or cut off, which would cause the rotary energy conversion switcher to vibrate.

[0058] The rotary energy conversion switch provided by this invention divides the switching valve chamber into a first sub-chamber, a second sub-chamber, a third sub-chamber, and a fourth sub-chamber by means of a left sub-valve core, a middle sub-valve core, and a right sub-valve core disposed within the switching valve chamber. A first water channel is formed on the left and middle sub-valve cores, and a second water channel is formed on the right and middle sub-valve cores. A pair of second left-side water channels on the left sub-valve core communicate with the first sub-chamber to form a second flow channel. The first left-side water channel and the second sub-chamber on the left sub-valve core, along with the first middle water channel on the middle sub-valve core, communicate to form a first flow channel. The second right-side water channel and the third sub-chamber on the right sub-valve core, along with the second middle water channel on the middle sub-valve core, communicate to form a third flow channel. The right sub-valve core... A pair of first right-side water channels are connected to the fourth sub-cavity to form a fourth flow channel. By adjusting the rotation angle of the switching valve core in the switching valve cavity, the middle water inlet and the first upper water inlet can be connected through the first water channel or the second flow channel, the first upper water inlet and the first lower water inlet can be connected through the second flow channel, the middle water inlet and the second upper water inlet can be connected through the second water channel and the third flow channel, and the second upper water inlet and the second lower water inlet can be connected through the fourth flow channel. In this way, by adjusting the rotation angle of the switching valve core in the switching valve cavity, different water channels can be formed, which facilitates the rapid change of the working fluid flow direction through the rotary energy conversion switcher. This solves the problem of needing to quickly change the working fluid flow direction in the existing technology and enables the rapid delivery of desulfurization wastewater to the corresponding process.
