Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical wastewater treatment technology, specifically relating to a separation device suitable for chemical wastewater. Background Technology
[0002] Chemical wastewater refers to industrial wastewater containing various harmful substances generated during chemical production processes. It mainly includes reaction residues, byproducts, solvents, catalysts, and unreacted chemicals. Its composition is complex, often containing high concentrations of organic matter, heavy metals, acids and alkalis, toxic compounds, and suspended solids, characterized by strong pollution, high toxicity, and difficulty in degradation. Depending on the production process, chemical wastewater can be classified into organic wastewater, inorganic wastewater, high-salinity wastewater, and oily wastewater. Direct discharge without proper treatment will cause serious harm to water bodies and the ecological environment; therefore, targeted treatment is essential to meet discharge or reuse standards.
[0003] In the process of chemical wastewater treatment, suspended solids are usually separated by sedimentation tanks. However, traditional sedimentation tanks have a significant problem in actual operation: when the influent turbulence is strong, it will cause the liquid flow in the tank to be disordered, thereby interfering with the sedimentation process of suspended solids and reducing the separation efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a separation device suitable for chemical wastewater, aiming to solve the problems mentioned in the background art.

[0010] The advection component includes a connecting box disposed above and connected to the slow flow box, and an outlet box connected to the top of the connecting box and used to increase the liquid inflow area.
[0011] A connecting pipe connects the bottom of the connecting box and the slow-flow box, and a support block for supporting the connecting box is fixedly installed on the top of the slow-flow box.
[0012] The area of the top of the connecting box and the area of the top of the outlet box increase in a stepped manner, and the area of the top of the outlet box is larger than the area of the top of the connecting box.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0025] Example
[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a separation device suitable for chemical wastewater, comprising:
[0027] The separation mechanism 100 includes a sedimentation tank 110, an inlet pipe 120 connected to the surface of the sedimentation tank 110, and an outlet pipe 130 connected to the surface of the sedimentation tank 110.
[0028] The liquid flow obstruction mechanism 200 includes a flow-slowing component 210 for slowing down the flow rate of liquid entering the inlet pipe 120; and a flow-adjusting component 220 for increasing the liquid inflow area.
[0029] The flow-retarding component 210 includes a flow-retarding component 210 fixedly installed on the inner wall of the sedimentation tank 110 and connected to the inlet pipe 120, a plurality of return pipes 212 connected to the surface of the flow-retarding box 211 and used for liquid return to slow down the flow rate, and a plurality of flow-blocking plates 213 fixedly installed inside the flow-retarding box 211 and used to block the flow of liquid.
[0030] The horizontal flow component 220 includes a connecting box 221 disposed above and communicating with the slow flow box 211, and an outlet box 222 communicating with the top of the connecting box 221 and used to increase the liquid inflow area.
[0031] A connecting pipe 223 connects the bottom of the connecting box 221 and the slow flow box 211, and a support block 224 for supporting the connecting box 221 is fixedly installed on the top of the slow flow box 211.
[0032] The area of the top of the connecting box 221 and the area of the top of the liquid outlet box 222 increase in a stepped manner, with the area of the top of the liquid outlet box 222 being larger than the area of the top of the connecting box 221.
[0033] The flow rate of chemical wastewater entering the sedimentation tank 110 is slowed down by the cooperation between the slow-flow component 210 and the horizontal flow component 220. This effectively reduces the impact of influent turbulence and solves the problem of decreased sedimentation efficiency caused by excessive influent flow rate in traditional sedimentation tank 110. This makes the flow of wastewater in the sedimentation tank more stable and improves the sedimentation efficiency of suspended solids.
[0034] The connection between the connecting box 221 and the outlet box 222 is used to increase the area of liquid flowing into the sedimentation tank 110 in a step-like manner, so that the liquid flows in smoothly and avoids affecting the settling inside the sedimentation tank 110.
[0035] The support block 224 is used to support the connecting box 221, thereby improving the installation stability of the connecting box 221 and preventing it from shifting and causing the connection between the connecting pipe 223 and the connecting box 221 to break.
[0036] Specifically, the inner wall of the sedimentation tank 110 is fixedly equipped with a reinforcing rod 214 for strengthening the support of the slow-flow box 211, and the top of the reinforcing rod 214 is fixedly installed at the bottom of the slow-flow box 211.
[0037] Among them, the reinforcing rod 214 is used to strengthen the support of the flow control box 211 and improve the stability of the flow control box 211 in use.
[0038] Furthermore, the baffle plate 213 is inclined, and the inclination direction is closer to the water inlet pipe 120.
[0039] In use, when chemical wastewater flows into the sedimentation tank 110 through the inlet pipe 120, the chemical wastewater first flows into the slow flow box 211 through the inlet pipe 120. The baffle plate 213 will block the flow of the chemical wastewater and reduce the flow rate of the chemical wastewater. At the same time, the chemical wastewater flows into the return pipe 212 and returns the chemical wastewater to the slow flow box 211. The returning chemical wastewater impacts the chemical wastewater flowing into the slow flow box 211, reducing the kinetic energy of the chemical wastewater and slowing down the flow rate of the chemical wastewater.
[0040] The chemical wastewater then flows into the connecting box 221 through the connecting pipe 223. Due to its upward flow, it is obstructed by the gravity of the chemical wastewater itself, which slows down the flow rate of the chemical wastewater. When the chemical wastewater enters the outlet tank 222, the area of the top of the outlet tank 222 is larger than the area of the top of the connecting box 221, which increases the area of the chemical wastewater flowing into the sedimentation tank 110, making the chemical wastewater flow into the sedimentation tank 110 more smoothly.
[0041] In summary, by coordinating the flow-slowing component 210 and the flow-adjusting component 220, the flow velocity of the chemical wastewater entering the sedimentation tank 110 is slowed down, effectively reducing the impact of influent turbulence. This solves the problem of decreased sedimentation efficiency in traditional sedimentation tanks 110 due to excessively fast influent flow velocity, making the flow of wastewater in the sedimentation tank more stable and improving the sedimentation efficiency of suspended solids.
