Description

Technical Field

[0001] The invention relates to the technical field of power plant wastewater treatment, and in particular to a rotary energy conversion switcher. Background Art

[0002] At present, the standards for wastewater discharge are very strict, and water environment protection has been elevated to a strategic level. As for power plants, as major users of water and discharge, 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] At present, the desulfurization wastewater volume of a 2×600MW thermal power generating unit is usually about 15t / h. With the improvement of the national wastewater discharge standards for the environmental protection industry, desulfurization wastewater urgently needs to be treated with zero discharge. At present, in the field of zero discharge treatment of desulfurization wastewater, the main process is to use membrane method for concentration and reduction. The TDS of desulfurization wastewater is usually about 50,000ppm. After being concentrated by multi-stage reverse osmosis membrane, the TDS of concentrated brine can reach 100,000ppm. Then the concentrated brine is sent to the crystallization evaporation drying process to finally form crystalline salt solids.

[0004] In current projects, the desulfurization wastewater is usually pressurized by 100% of the water volume and enters the high-pressure pump. Then, it continues to pressurize the high-pressure pump and enters the reverse osmosis system. Through the concentration and separation of the reverse osmosis membrane, it is partially concentrated into high-TDS high-pressure brine. In order to overcome the osmotic pressure of the high-TDS desulfurization wastewater, the desulfurization wastewater requires a very high water inlet pressure (50bar~120bar) in the reverse osmosis membrane system. After reverse osmosis concentration, the pressure of the high-TDS brine is often reduced by 1~2bar. After that, the high-pressure brine of this part of the reverse osmosis system is usually reduced by valve regulation or flow-limiting orifice plate. It is usually reduced to less than 10bar. The low-pressure brine after decompression enters the crystallization evaporation and drying process. Therefore, there is a huge waste of energy in the current membrane concentration and reduction process.

[0005] During the entire process of desulfurization wastewater treatment, the desulfurization wastewater needs to be sent to the corresponding treatment process. Therefore, a device is urgently needed to quickly send the desulfurization wastewater to the corresponding process. Summary of the invention

In this way, when the switching valve core 2 rotates, the working medium flowing through the corresponding water channel or flow channel will not be interrupted due to the connection of the overlapping grooves 26, so that the working medium from the middle water port 15 continuously flows into the switch and flows out from the first water port 11 or the second water port 13, and has the structural characteristics of flowing out from the first water port 11 and the second water port 13 at a specific rotation angle, and then enters 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 outlet on the side wall where the cavity contacts is arranged across the water outlet, and the buffer groove 27 at the water outlet on the side wall where the first right side water channel 242 is located and contacts with the switching valve cavity on the right side sub-valve core 24 is also arranged across the water outlet. The buffer groove 27 is arranged to prevent the working fluid flowing through the corresponding flow channel from slowly entering or flowing out of the corresponding flow channel due to the existence of the buffer groove 27 when a large amount of working fluid flows through the rotary energy conversion switcher when the switching valve core 2 rotates to switch the water channel or flow channel, thereby preventing the water channel or flow channel from being suddenly connected or cut off, causing the rotary energy conversion switcher to vibrate.

A first water channel is provided on the left sub-valve core and the middle sub-valve core, and a second water channel is provided on the right sub-valve core and the middle sub-valve core. A pair of second left side water channels on the left sub-valve core are connected with the first sub-chamber to form a second flow channel. The first left side water channel on the left sub-valve core, the second sub-chamber and the first middle water channel on the middle sub-valve core are connected to form the first flow channel. The second right side water channel on the right sub-valve core, the third sub-chamber and the second middle water channel on the middle sub-valve core are connected to form a third flow channel. A pair of first right side water channels are connected with the fourth sub-cavity to form a fourth flow channel, and the rotation angle of the switching valve core in the switching valve cavity is adjusted, 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, adjusting the rotation angle of the switching valve core in the switching valve cavity can form different water channels, thereby facilitating the rapid change of the working fluid flow direction through the rotary energy conversion switcher, solving the problem of the need to rapidly change the working fluid flow direction in the prior art, and being able to rapidly transport the desulfurization wastewater to the corresponding process.
