Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cyclone desanders, and more specifically to a cyclone desander for gas-water separation in geothermal reinjection. Background Art
[0002] The cyclone desander is made based on the screening principle of solid particles in the fluid when they rotate in the desander. It integrates cyclone and filtration, and achieves the effects of sand removal, turbidity reduction, solid-liquid separation, etc. through centrifugal separation. When water flows into the equipment tangentially from the desander water inlet under a certain pressure, it will produce a strong rotational motion. Due to the different densities of sand and water, under the combined action of centrifugal force, centripetal force, buoyancy and fluid drag, the water with low density will rise and be discharged from the outlet, while the sand with high density will settle to the sewage outlet at the bottom of the equipment and be discharged, thereby achieving the purpose of sand removal.
[0003] The shortcomings of existing cyclone desanders: Traditional cyclone desanders are bottom-in and top-out. Because they have no gas-water separation capability, in order to prevent gas blockage, the gas separated from the well water must be taken away from the top with the water flow. Therefore, traditional cyclone desanders can only be designed with bottom-in and top-out. Because the well water in the barrel swirls upward, only larger particles of sand can break through the lift of the upward swirling water flow and settle downward, and the fine mud and sand are taken away by the water flow. The leakage of fine particles limits the overall sand removal efficiency of the desander, and it is impossible to achieve higher purification standards. Utility Model Content

[0024] In a preferred embodiment, one side of the folding block 401 is fixedly connected to the second transmission rod 403, one side of the second transmission rod 403 is fixedly connected to the first conical tooth 404, the top of the outer surface of the first conical tooth 404 is movably connected to the second conical tooth 405, and the top of the second conical tooth 405 is fixedly connected to the second motor 406.
[0025] In a preferred embodiment, a support leg 101 is fixedly connected to the outer surface of the desander body 1 , and a water outlet 102 is formed on the other side of the outer surface of the desander body 1 .
[0026] In a preferred embodiment, the diameter of the second gear 202 is twice that of the first gear 201 .
[0027] The working principle of the utility model is as follows: the water inlet 3 puts the well water mixed with impurities into the interior of the desander body 1, and the first motor 2 is started to rotate the first gear 201. After the first gear 201 rotates, the second gear 202 starts to rotate. At this time, the first transmission rod 203 at the bottom of the second gear 202 drives the cylinder 302 to rotate. At this time, the well water mixed with impurities enters the interior of the desander body 1 through the circulation groove 303, and the first impeller 304 and the second impeller 305 on the cylinder 302 start to rotate, so that the well water mixed with impurities swirls downward, and the water flow guiding force, centrifugal force and sediment gravity are cleverly used. The synthesis of these three forces can swirl the fine sediment in the well water to the bottom of the desander body 1. The setting of the dirt blocking sheet 306 can prevent the sediment from moving upward and make it sink to the bottom quickly. Through the rotation of the first impeller 304 and the second impeller 305 on the cylinder 302, the well water mixed with impurities is guided to form a swirl This vortex utilizes the combined effects of water flow guiding force, centrifugal force and sediment gravity, so that the fine sediment in the well water can be efficiently driven by the vortex and settled to the bottom of the desander body 1. This design significantly improves the efficiency and effect of desandering. In order to prevent sediment from clogging the lower sewage outlet 4, the second motor 406 is started to make the second conical teeth 405 start to rotate. When the second conical teeth 405 start to rotate, the first conical teeth 404 start to rotate. When the first conical teeth 404 start to rotate, the second transmission rod 403 drives the folding block 401 to rotate, and the front surface 402 on the folding block 401 can loosen and discharge the accumulated sediment more quickly. The folding block 401 and the front surface 402 thereon are rotated by the drive of the second motor 406, and the sediment accumulated in the lower sewage outlet 4 can be stirred and loosened as needed, effectively preventing the sediment from clogging the lower sewage outlet 4, and ensuring the smooth progress of the desandering process.
