Detailed Implementation

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0020] See Figure 1As shown, a high-efficiency reactor device for removing silicon and silicides from wastewater includes a reactor body 1, which is divided into a reaction zone 2, a separation zone 3, and a deposition zone 4. The reaction zone 2 of the reactor body 1 is provided with a water inlet. A separation zone 3 is provided between the reaction zone 2 and the deposition zone 4. The deposition zone 4 is located directly below the separation zone 3. A high-speed stirring device 5 is fixedly installed in the reaction zone 2. A crystal nucleus recovery port is fixedly opened in the deposition zone 4. A pneumatic diaphragm pump 6 is connected to the crystal nucleus recovery port. The output end of the pneumatic diaphragm pump 6 is connected to the reaction zone 2.

[0021] Reaction zone 2 is equipped with a wastewater inlet and a dosing port. Wastewater enters reaction zone 2 through the inlet, and high-temperature sintered quartz sand core crystals (diameter not greater than 1 mm) are added through the dosing port. The mixture is stirred evenly by a high-speed stirring device 5. Reaction zone 2 is acidic. When the high-speed motor rotates (for 2 minutes forward, then for 1 minute reverse), the crystal nuclei collide with silicon and silicides at high speed. During the collision, silicon and silicides crystallize on the surface of the crystal nuclei, and the crystal nuclei gradually grow larger. The fully reacted wastewater enters the water distribution zone and is evenly distributed. The wastewater is separated in the inclined plate mud-water separation zone 3. The crystal nuclei sink into the mud hopper zone, and the supernatant enters the effluent tank 8 for discharge after meeting the standards. After the core crystal nuclei are collected in the mud hopper zone, they are lifted to reaction zone 2 by a pneumatic diaphragm pump 6. The above reaction process is repeated. When the crystal nuclei directly exceed 3 mm, they should be replenished or replaced. The replacement time of the core crystal nuclei can be controlled according to the concentration of silicon and silicides.

[0022] The high-speed stirring device 5 includes a high-speed stirring motor 51 and a high-speed stirring head 52. The high-speed stirring motor 51 is fixedly installed outside the reaction device body 1, and the output end of the high-speed stirring motor 51 passes through the reaction device body 1 and is fixedly connected to the high-speed stirring head 52.

[0023] An inclined plate assembly is fixedly installed in the separation zone 3, and a water outlet is fixedly opened on the side of the separation zone 3 away from the reaction zone 2.

[0024] The inclined plate assembly includes a fixing frame 71, a water distribution perforated plate 72, a fixing base 73, a baffle 74, and a separation inclined plate 75. The baffle 74 is fixedly installed on the reaction device body 1 directly above the side of the fixing base 73 adjacent to the reaction zone 2. The fixing frame 71 is fixedly installed on the reaction device body 1 above the fixing base 73. A plurality of separation inclined plates 75 are fixedly installed between the fixing frame 71 and the fixing base 73. A separation inlet is provided between the fixing base 73 and the baffle 74. A water distribution perforated plate 72 is fixedly installed at the separation inlet.

[0025] The spacing between the separating inclined plates 75 gradually decreases, and the side of the separating inclined plates 75 adjacent to the water distribution plate 72 has a large spacing.

[0026] The separating inclined plate 75 includes an inclined plate body and a vertical guide plate, the inclined plate body and the guide plate being an integral structure.

[0027] The front of the separation inclined plate 75 has a large load and a larger plate spacing, while the rear has a small load and a smaller plate spacing, which improves the efficiency of mud-water separation. The lower section of the separation inclined plate 75 is chamfered, i.e., a vertical guide plate, which makes the crystal nuclei gather at the bottom of the mud hopper more quickly and improves the sedimentation effect.

[0028] A water outlet baffle 9 is fixedly installed on the reaction device body 1 at the water outlet. The water outlet baffle 9 forms a water outlet trough 8, and the highest height of the water outlet baffle 9 is higher than the highest height of the inclined plate assembly.
