Description

TECHNICAL FIELD

[0001] The present application relates to the field of wastewater treatment, in particular to a boiler wastewater treatment device. BACKGROUND

[0002] Boiler wastewater refers to various types of wastewater or wastewater generated during the operation, maintenance and related processes of the boiler, and its composition and properties vary greatly due to different types of boilers, fuel types, operating parameters and water treatment processes. If such wastewater is not properly treated before being discharged, it may pollute the environment, so it needs to be treated and controlled accordingly.

[0003] Because there are various types of chemical molecules remaining in the boiler wastewater, it cannot be simply treated by physical steps such as filtration during the treatment process, but needs to be neutralized by reagents such as precipitants and neutralizing agents. This not only forces the precious metals to precipitate, but also neutralizes the pH value, reducing its harm to the environment.

[0004] In the prior art, when chemical treatment is performed, the wastewater is directly guided into the inside of the reaction tank, and then reagents are added to achieve chemical treatment. However, in actual operation, the total amount of wastewater treated each time cannot remain exactly the same, so it is impossible to determine the total amount of reagents needed each time. If too much reagent is added, it will be wasted, and if too little reagent is added, it will not be completely treated. Therefore, a boiler wastewater treatment device is proposed to solve the above problems. SUMMARY

[0005] The purpose of the present application is to solve the problems raised in the background art, and a boiler wastewater treatment device is proposed.

In this way, the size of the inside space of the liquid storage box can be changed, so that the size of the inside space of the liquid storage box can adapt to the total amount of wastewater.

[0037] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.

[0038] As Figures 1-3As shown, one embodiment of the present invention provides a boiler wastewater treatment device, including a tank 1. The tank 1 supports the entire device. The tank 1 is a rectangular tank with an open top, which facilitates the discharge of gas generated during the reaction inside the device and allows for easy cleaning of the tank 1 by the operator. A cover plate 2 is installed on the upper surface of the tank 1 to close the top opening of the tank 1. A depth measuring component 3 for measuring the total amount of wastewater is provided on the upper surface of the cover plate 2. A drainage component 5 for discharging chemical solution is provided on the inner wall of the tank 1. A storage component 4 for storing chemical solution is provided on the right surface of the tank 1. The depth measuring component 3 is used to measure the liquid depth inside the tank 1. Since the cross-section of the inner wall of the tank 1 is the same everywhere, the depth can be measured through the tank. The total amount of sewage can be estimated by measuring the height of the sewage inside the pool 1. The depth measuring component 3 includes a buoyancy plate 31. The lower surface of the buoyancy plate 31 is horizontal. When sewage flows into the pool 1, the buoyancy plate 31 will be forced to move upward. The buoyancy plate 31 is slidably connected to the inner wall of the pool 1, and the outer wall of the buoyancy plate 31 is attached to the inner wall of the pool 1. This can prevent the buoyancy plate 31 from rotating randomly inside the pool 1. A sliding rod 32 is fixedly connected to the upper surface of the buoyancy plate 31. When the buoyancy plate 31 moves up and down, the sliding rod 32 will also be driven to move synchronously. A sliding plate 33 is fixedly connected to the upper end of the sliding rod 32. When the sliding rod 32 moves upward, it will push the sliding plate 33 to move upward synchronously. A piston rod 36 is provided on the right surface of the sliding plate 33.

[0039] like Figures 2-4 As shown, the liquid storage assembly 4 includes a liquid storage box 41 for temporary storage of the liquid medicine. The liquid storage box 41 is made of transparent material, which allows the operator to easily observe the liquid storage situation inside. The liquid storage box 41 is installed on the right surface of the pool body 1. A piston plate 43 is fixedly connected to the lower surface of the piston rod 36 to adjust the size of the internal space of the liquid storage box 41. The piston plate 43 is piston-connected to the inner wall of the liquid storage box 41. The space between the lower surface of the piston plate 43 and the bottom of the inner wall of the liquid storage box 41 is the liquid medicine storage space. By changing the size of this space, the total amount of liquid medicine temporarily stored can be changed. The lower surface of the storage box 41 is provided with a flow pipe 42 for discharging the medicine solution. The upper end of the flow pipe 42 is installed on the inner wall of the storage box 41. The medicine solution stored inside the storage box 41 can be discharged through the flow pipe 42. The left end of the flow pipe 42 is installed on the inner wall of the pool body 1. In actual use, in order to prevent the sewage inside the pool body 1 from flowing back into the storage box 41, a one-way valve can be installed on the inner wall of the flow pipe 42. The sewage mentioned in this embodiment is alkaline sewage with a density of 1.05~1.1g / cm³, and the neutralizing agent used in this embodiment is CO. 2 The water volume has a density of approximately 0.77 g / cm³, therefore, CO is injected into the storage tank 41. 2 The aqueous solution can force the sewage inside the storage box 41 to be discharged.

[0040] like Figure 3, Figure 4 and Figure 7 As shown, the depth measuring component 3 includes a guide rod 34 for guiding the movement of the slide plate 33. The guide rod 34 is fixedly connected to the upper surface of the cover plate 2 and is set perpendicular to the cover plate 2. The slide plate 33 is slidably connected to the outer wall of the guide rod 34. By guiding the movement of the slide plate 33 through the guide rod 34, the slide plate 33 can be guided to move vertically up and down. A sealing block 35 for sealing the top of the guide rod 34 is fixedly connected to the top of the guide rod 34. By setting the sealing block 35, the slide plate 33 can be prevented from separating from the guide rod 34. The lower end of the liquid storage box 41 is equipped with an air inlet pipe 44 and a drug delivery pipe 45 from front to back. The open ends of the air inlet pipe 44 and the drug delivery pipe 45 are respectively connected to a high-pressure air pump and a drug delivery pipeline. The high-pressure air pump can inject gas into the liquid storage box 41, which can force the liquid inside the liquid storage box 41 to be discharged. The drug delivery pipeline is directly connected to the drug storage tank and can be used to input liquid into the liquid storage box 41.

[0041] like Figures 2-4 As shown, the left surface of the pool body 1 is provided with an inlet 12 for sewage to enter the interior of the pool body 1, and the bottom end of the pool body 1 is provided with a drain outlet 11 for sewage to be discharged. A limiting ring 37 is provided on the inner wall of the pool body 1 near the upper part of the inlet 12. The limiting ring 37 is horizontally set on the inner wall of the buoyancy plate 31. The limiting ring 37 can prevent the buoyancy plate 31 from moving downward. By setting the limiting ring 37, the buoyancy plate 31 can be prevented from moving below the inlet 12.

[0042] like Figures 4-6As shown, the drainage assembly 5 includes a drainage pipe 51 for containing a gas-liquid mixture. The drainage pipe 51 is rotatably connected to the inner wall of the tank body 1. The upper surface of the drainage pipe 51 is provided with a drainage hole 56 for guiding the gas-liquid mixture out. By changing the orientation of the drainage pipe 51, the orientation of the drainage hole 56 can be changed, thus changing the discharge direction of the gas-liquid mixture. The left end of the flow pipe 42 connected to the tank body 1 is installed on the inner wall of the drainage pipe 51. This flow pipe 42 can be used to guide the liquid medicine inside the storage box 41 into the inner wall of the drainage pipe 51. A fusion pipe 54 for guiding the mixture of liquid medicine and gas is fixedly connected to the inner wall of the drainage pipe 51. The fusion pipe 54 is a hollow circular tube with a hollow interior and openings on both sides. The gas-liquid mixture can enter the interior of the fusion pipe 54 from the right opening and exit from the left opening of the fusion pipe 54. The internal structure of the 4-channel detaches, and the left end of the flow pipe 42 is connected to the fusion pipe 54. The inner wall of the drain pipe 51 is fixedly connected to an orifice plate 57 for guiding the gas-liquid mixture to form bubbles. The left end of the fusion pipe 54 is fixedly connected to the right end of the orifice plate 57. When the drug is administered, the gas-liquid mixture discharged from the left end of the fusion pipe 54 will pass through the orifice plate 57, thus forming bubbles. Subsequently, this part of the gas-liquid mixture will pass through the orifice plate 57 again from left to right, thereby further refining the bubbles. The inner wall of the fusion pipe 54 is provided with a guide plate 55 for guiding the flow of the gas-liquid mixture. The guide plate 55 is spiral-shaped. When the gas-liquid mixture passes through the inside of the fusion pipe 54, it will rotate under the guidance of the guide plate 55, thus promoting the mixing of gas, liquid and water. A gap is provided between the inner walls of the fusion pipe 54 and the drain pipe 51.

[0043] like Figures 3-5 As shown, a transmission rod 53 for driving the drainage pipe 51 to rotate is fixedly connected to the left end of the drainage pipe 51. The left end of the transmission rod 53 passes through and is rotatably connected to the left end of the pool body 1. When the transmission rod 53 rotates, it will drive the drainage pipe 51 to rotate synchronously, thus changing the exhaust direction of the drainage pipe 51. An adjustment motor 52 for providing power for rotation is installed at the left end of the pool body 1. The adjustment motor 52 is a servo motor, and its rotation direction and rotation angle and other parameters can be adjusted. The output shaft of the adjustment motor 52 is connected to the transmission rod 53 through belt drive. By starting the adjustment motor 52, the transmission rod 53 can be driven to rotate. An opening is provided on the upper surface of the cover plate 2 near the left end. The upper surface area of ​​the buoyancy plate 31 is larger than the surface area of ​​the opening on the upper surface of the cover plate 2.

[0044] Working principle: After the wastewater enters the tank 1 through the inlet 12, the liquid level rises and pushes the buoyancy plate 31 to move upward. The buoyancy plate 31 drives the slide plate 33 to move upward along the guide rod 34 via the slide rod 32. The piston rod 36 on the right side of the slide plate 33 then drives the piston plate 43 to move upward in the liquid storage box 41. By changing the size of the internal space of the liquid storage box 41 to adapt to the total amount of wastewater, the dosing capacity can be automatically adjusted according to the wastewater volume.

[0045] When the drug is administered, the liquid medicine in the liquid storage box 41 enters the fusion pipe 54 of the liquid discharge assembly 5 through the liquid flow pipe 42, and at the same time, the high-pressure gas pump introduces gas into the inside of the liquid storage box 41 through the corresponding gas inlet pipe 44, the liquid medicine and the gas will enter the fusion pipe 54 together, and will be guided to form a rotating flow in the fusion pipe 54 by the spiral flow guide plate 55, and after being mixed sufficiently, it is refined into gas-liquid bubbles through the perforated plate 57.

[0046] During the liquid discharge process, the adjusting motor 52 drives the transmission rod 53 to rotate through the belt, drives the liquid discharge pipe 51 to rotate to change the direction of the liquid discharge hole 56, so that the bubbles are uniformly diffused to each area of the pool body 1 from multiple angles, and the reaction efficiency is improved.

[0047] At the same time, the buoyancy plate 31 cooperates with the cover plate 2 to block the sewage, so that the reaction gas can be discharged from the opening of the cover plate 2, and the liquid is prevented from splashing, and the treated wastewater is finally discharged through the drain port 11.

[0048] In the description of the present application, the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "vertical", "horizontal" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of describing the present application and do not require the present application to be constructed or operated in a particular orientation, therefore cannot be understood as a limitation on the present application. The "connection" in the present application should be understood broadly, for example, it can be connected, or it can be detachable connection; it can be direct connection, or it can be indirect connection through intermediate components, and the specific meaning of the above terms can be understood according to the specific circumstances for those skilled in the art.

[0049] The above is the preferred operation mode of the present application, and the description of the specific operation mode is only for better understanding the idea of the present application. For ordinary skilled in the art, according to the principle of the present application, several improvements or equivalent replacements can also be made, and these improvements or equivalent replacements are also considered to fall within the protection scope of the present application.
