Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal power plant equipment, in particular to a raw water treatment flocculation tank in a thermal power plant. Background Art
[0002] Raw water treatment at thermal power plants primarily involves purifying raw water to produce the quality and quantity of make-up water required by the thermal system. This includes processes such as coagulation, clarification, and filtration to remove suspended solids and colloidal impurities from the natural water; softening to remove hardness components such as dissolved calcium and magnesium ions; and desalination to remove all dissolved salts. These treatment steps are designed to ensure the quality of the make-up water.
[0003] However, in actual operation, it was found that the conventional guide tube structure resulted in poor mixing of particles, colloids, and chemicals inside the flocculation tank, and the flocculation effect was not optimal, resulting in a waste of resources. Moreover, after the flocculation tank completed the treatment, the flocculants in the liquid would flow with the discharged water, and even cause blockage in the drain pipe, affecting the efficiency of liquid discharge. Summary of the Invention
[0004] The purpose of the utility model is to provide a flocculation tank for treating raw water in a thermal power plant, so as to solve the above-mentioned defects caused by the prior art.
[0005] The raw water treatment flocculation tank of a thermal power plant includes a treatment tank body and a storage tank body. A discharge pipe is connected through one side of the treatment tank body, and a sewage pipe is connected through one side of the treatment tank body. A displacement mechanism is provided directly above the treatment tank body. During the dynamic displacement process, the displacement mechanism injects materials into the raw water, thereby accelerating the reaction of the raw water and the flocculation efficiency. A treatment mechanism is provided inside the storage tank body. The storage tank body grinds the injected material and mixes the liquid through the liquid mixing mechanism to accelerate the reaction of the agent with the raw water and the filtration efficiency.
[0006] Preferably, the displacement mechanism includes a guide rail, a bracket, a motor, an electric telescopic rod and a storage tank body. The storage tank body is installed on the outside of the bracket, and a motor is provided at the top of the storage tank body. The left and right sides of the bracket are connected to the guide rails, and the guide rails are symmetrically arranged at the top of the processing tank body. One side of the processing tank body is connected to the electric telescopic rod, and the output end of the electric telescopic rod is connected to one side of the bracket.
[0007] Preferably, the treatment tank body is connected to one side of the bracket via an electric telescopic rod connected to one side.
[0008] Preferably, the processing mechanism includes a storage tank body, a drive shaft, mixing blades, a separation box body, a corrugated filter plate, a grinding roller and a leakage hole. The output end of the motor is connected to the drive shaft, the outer side of the drive shaft is connected to the grinding roller, the bottom end of the drive shaft is connected to the mixing blades, the mixing blades are arranged inside the processing tank body, the mixing blades are arranged inside the storage tank body, the separation box body is arranged inside the processing tank body, and corrugated filter plates are arranged at equal intervals inside the separation box body.
[0009] Preferably, the motor is connected to the outer side of the mixing blade via a drive shaft connected to the output end.
[0010] Preferably, the storage tank is connected to the outer side of the drive shaft via a grinding roller arranged inside.
[0011] Compared with the prior art, the utility model has the following advantages:
[0012] 1. The bracket and the motor are moved laterally by the electric telescopic rod. On the one hand, the motor drives the grinding roller to rotate to grind the treatment chemicals, and then evenly spread the materials into the treatment tank to avoid the accumulation of chemicals in a part of the liquid, affecting the efficiency of liquid reaction and mixing. On the other hand, the bracket drives the mixing blade to move laterally, and then dynamically mix the liquid to reduce the dead angle of the chemical reaction in the treatment tank.
[0013] 2. At the same time, the corrugated filter plate is used to filter the impurities in the liquid to prevent the liquid from flowing directly into the side of the separation box. The residual flocculants in the tank are then flowed into the interior of the treatment tank through the recess on one side of the treatment tank. The liquid is then directly discharged through the sewage pipe on one side, thereby improving the efficiency of cleaning the internal flocculants of the treatment tank and avoiding the blockage of the drainage pipe caused by the direct discharge of a large amount of flocculants.

A discharge pipe 7 is connected to one side of the treatment tank body 1, and a sewage pipe 8 is connected to one side of the treatment tank body 1. A displacement mechanism 6 is provided directly above the treatment tank body 1. The displacement mechanism 6 injects materials into the raw water during the dynamic displacement process, thereby accelerating the reaction of the raw water and the flocculation efficiency. A treatment mechanism 10 is provided inside the storage tank body 9. The storage tank body 9 grinds the injected material and mixes the liquid through the liquid mixing mechanism to accelerate the reaction of the agent with the raw water and the filtration efficiency.
[0023] In this embodiment, the displacement mechanism 6 includes a guide rail 2, a bracket 3, a motor 4, an electric telescopic rod 5 and a storage tank body 9. The storage tank body 9 is installed on the outside of the bracket 3. The top of the storage tank body 9 is provided with a motor 4. The left and right sides of the bracket 3 are connected to the guide rail 2. The guide rail 2 is symmetrically arranged at the top of the treatment tank body 1. One side of the treatment tank body 1 is connected to the electric telescopic rod 5. The output end of the electric telescopic rod 5 is connected to one side of the bracket 3. The storage tank body 9 is laterally displaced by the bracket 3 to facilitate uniform spreading reaction of the liquid.
[0024] In this embodiment, the treatment tank body 1 is connected to one side of the bracket 3 through an electric telescopic rod 5 connected to one side. The electric telescopic rod 5 is used to pull both sides of the bracket 3 to dynamically adjust the position of the bracket 3.
[0025] In this embodiment, the processing mechanism 10 includes a storage tank body 9, a drive shaft 11, a mixing blade 12, a separation box 13, a corrugated filter plate 14, a grinding roller 15 and a leakage hole 16. The output end of the motor 4 is connected to the drive shaft 11, the outer side of the drive shaft 11 is connected to the grinding roller 15, the bottom end of the drive shaft 11 is connected to the mixing blade 12, the mixing blade 12 is arranged inside the processing tank body 1, the storage tank body 9 is provided with a mixing blade 12, the separation box 13 is provided inside the processing tank body 1, and the interior of the separation box 13 is provided with corrugated filter plates 14 at equal intervals. The corrugated filter plates 14 are used to filter the liquid to prevent a large amount of flocculants in the liquid from being discharged with the liquid.
[0026] In this embodiment, the motor 4 is connected to the outer side of the mixing blade 12 via the driving shaft 11 at the output end, and the liquid is displaced and mixed by the mixing blade 12 to accelerate the efficiency of the liquid reaction.
[0027] In this embodiment, the storage tank body 9 is connected to the outer side of the driving shaft 11 through the grinding roller 15 provided inside the storage tank body 9. The material is ground by the grinding roller 15 inside the storage tank body 9 and then discharged into the liquid, thereby improving the efficiency of liquid flocculation.
[0028] In actual application, the flocculation tank for raw water treatment in thermal power plants includes the following tasks:
[0029] Step 1: The operator first injects the treatment water directly into the interior of the treatment tank body 1, and after waiting for a certain amount of water to be injected, the treatment material is directly introduced into the interior of the storage tank body 9. The motor 4 drives the drive shaft 11 and the grinding roller 15 to rotate, and the grinding roller 15 grinds the medicine. At the same time, the multiple groups of leakage holes 16 set at the bottom are used to guide the ground material out of the interior of the storage tank body 9 to react with the internal liquid of the treatment tank body 1. At the same time, the electric telescopic rod 5 set on one side is used to pull the bracket 3 horizontally;
[0030] Step 2: The bracket 3 reciprocates left and right at the top of the treatment tank body 1 through the guide rails 2 provided on both sides, thereby switching the position of the material spreading. At the same time, the motor 4 is used to drive the mixing blade 12 to rotate, thereby promoting the migration and collision aggregation of fine particles in the water, and the suspended flocs have an adsorption effect on the fine flocs. When the reaction and mixing of the liquid are completed, the motor 4 is turned off, so that the liquid inside the treatment tank body 1 is still, and the suspended matter is settled to the bottom of the treatment tank body 1;
[0031] Step 3: The operator first extracts the settled liquid through the discharge pipe 7 provided on one side, and then extracts the liquid in the treatment tank body 1. After extracting two-thirds of the liquid in the treatment tank body 1, the operator discharges the remaining liquid in the treatment tank body 1 through the sewage pipe 8 provided on the side of the treatment tank body 1. The flocculants in the liquid are filtered through the corrugated filter plate 14, and the filtered liquid is discharged;
[0032] Step 4: After the liquid in the treatment tank body 1 is drained, the operator removes the separation box 13 and the corrugated filter plate 14, removes the flocculants on the corrugated filter plate 14, and then flushes the treatment tank body 1 with liquid so that the remaining flocculants flow to the concave part on one side of the treatment tank body 1, and then directly discharges the sewage and flocculants through the sewage pipe 8.
[0033] Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
