Description

Technical Field

[0001] The utility model belongs to the technical field of flocculant addition, and specifically relates to a flocculant adding device for water pollution prevention and control. Background Art

[0002] Flocculants used in water pollution prevention and control are chemical substances used to treat suspended matter and turbidity in water. The function of flocculants is to aggregate tiny suspended particles in water into larger clumps (floccules) to facilitate subsequent precipitation or filtration removal, thereby purifying water quality. In practical applications, the treatment effect of a single flocculant is not ideal, and composite flocculants are often used to increase the flocculation efficiency. The formula of these composite flocculants can be adjusted according to the specific water quality conditions and treatment requirements to achieve the best flocculation effect and water purification effect. Inorganic flocculants such as aluminum sulfate, ferric chloride, etc., these inorganic substances usually have a strong flocculation effect and can quickly aggregate suspended matter in water into larger clumps. Organic flocculants such as polyacrylamide (PAM) and its derivatives, etc., flocculants can effectively condense suspended particles through the compression of double electrical layers, adsorption and neutralization, adsorption bridging and net capture and sweeping. Auxiliary ingredients may include surfactants, buffers, pH regulators, etc., which help to improve the stability and adaptability of flocculants.

[0003] Existing flocculants are usually mixed and added to different water pollution control pools. If they are left standing for too long, the flocculants will be redispersed or the structure will become loose, reducing their ability to treat suspended matter in the water. Utility Model Content

[0004] In view of this, the utility model provides a flocculant adding device for water pollution control, which can solve the problem that the existing flocculants are usually mixed and added to different water pollution control pools, and the standing time is too long, which will cause the flocculants to disperse again or the structure to loosen, thereby reducing its ability to treat suspended matter in the water.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a flocculant adding device for water pollution control, which comprises a feed pipe, a static mixing component and a discharge pipe. The feed pipe comprises a plurality of pipes, which are respectively connected to different flocculant raw material storage tank groups. The other end of the feed pipe is connected to the static mixing component. The feed pipe is used to input different types of flocculants into the static mixing component for mixing. One end of the static mixing component away from the feed pipe is connected to the discharge pipe. The discharge pipe is used to output the mixed flocculants to a water pollution control pool.

[0007] The technical effect of a flocculant adding device for water pollution prevention and control provided by the utility model is as follows: by setting a plurality of feed pipes, the raw materials of the flocculant before mixing are mixed before use, which can solve the problem that the existing flocculants are usually added to different water pollution prevention and control pools after mixing, and the standing time is too long, which will cause the flocculant groups to be dispersed again or the structure to be loose, thereby reducing its ability to treat suspended matter in water; different types of flocculants can be mixed in the required proportion to cope with the treatment requirements of different water qualities and pollutants. This structure ensures the accuracy and flexibility of the addition process, and can dynamically adjust the dosage of different flocculants according to water quality analysis. Through the static mixing component, different types of flocculants can be fully mixed to form a uniform flocculant solution or suspension. This uniform mixing helps to ensure the efficient removal or precipitation of pollutants in the subsequent treatment stage. Through the discharge pipe, the mixed flocculant can be accurately transported to the target treatment area to further react with the pollutants in the water. This ensures the continuity and stability of the treatment process, and at the same time, the output flow rate and speed can be adjusted as needed to optimize the treatment effect.

[0008] On the basis of the above technical solution, the flocculant adding device for water pollution control of the utility model can also be improved as follows:

[0009] Wherein, a multi-way connector is provided between the feed pipe and the static mixing component, one end of the multi-way connector is fixedly connected to the top of the static mixing component, and the other end is plugged into the bottom of the plurality of feed pipes.

[0010] Furthermore, a valve is provided inside the discharge pipe in a direction away from the static mixing component to prevent backflow inside the discharge pipe to avoid blockage.

[0011] Furthermore, the static mixing component is a cylindrical structure.

[0012] Furthermore, a plurality of baffles are fixed inside the static mixing component. The baffles are staggered inside the static mixing component and fixedly connected to the side walls of the static mixing component.

[0013] Furthermore, the baffle is a sheet-like structure, and the baffle is inclined toward the flow direction of the flocculant, and the angle between the baffle and the side wall of the static mixing component is 15-20°.

[0014] Furthermore, the discharge pipe is a cylindrical straight pipe, and the diameter of the discharge pipe is greater than the diameter of the feed pipe.

[0015] Furthermore, the position where the multi-way connector is connected to the feed pipe is bent in a direction away from the central axis of the multi-way connector.

[0016] Furthermore, metering pumps are provided on the plurality of feed pipes and the discharge pipes.

[0017] Furthermore, the metering pump on the feed pipe is used to extract different types of flocculants in proportion, and the metering pump on the static mixing component is used to add a quantitative amount of mixed flocculants into the water pollution control pool.

[0018] Compared with the prior art, the beneficial effects of the flocculant adding device for water pollution prevention and control provided by the utility model are:

[0019] The feed pipe includes a plurality of pipes, each of which is connected to a storage tank of a different type of flocculant and is used to transport the different types of flocculants to the static mixing component for mixing.

[0020] The static mixing assembly is a cylindrical structure with multiple baffles fixed inside. The baffles are staggered and installed obliquely in the cylinder; different types of flocculants from multiple feed pipes are mixed to ensure sufficient mixing and form a uniform mixture.

[0021] The discharge pipe is a cylindrical straight pipe with a valve inside that is away from the static mixing component to output the mixed flocculant to the water pollution control pool; the presence of the valve can prevent backflow inside the pipe and help avoid pipe blockage.

[0022] The multi-way connector connects multiple feed pipes and the static mixing assembly, with one end fixedly connected to the top of the static mixing assembly and the other end plugged into the bottom of the feed pipe, ensuring that the feed pipe is firmly connected to the static mixing assembly so that different types of flocculants can effectively enter the mixing process.

[0023] The baffle is installed inside the static mixing component. It is a sheet-like structure and is installed obliquely. The angle between it and the side wall of the static mixing component is 15-20 degrees, which helps guide the flow direction of the flocculant, promotes effective mixing between them, and ensures the uniformity of the mixture.

[0024] The metering pumps are installed on the feed pipe and the discharge pipe to accurately control the dosage of different types of flocculants and the output of the mixed flocculants to ensure the accuracy and efficiency of the treatment process. BRIEF DESCRIPTION OF THE DRAWINGS

The other end of the feed pipe 10 is connected with the static mixing component 20. The feed pipe 10 is used to input different types of flocculants into the static mixing component 20 for mixing; the end of the static mixing component 20 away from the feed pipe 10 is connected with the discharge pipe 30. The discharge pipe 30 is used to output the mixed flocculants to the water pollution control pool.

[0031] Both the feed pipe 10 and the discharge pipe 30 are made of a material that can tolerate a wide range of pH values, so as to be suitable for pH deviations of flocculants of different types and concentrations.

[0032] Among them, in the above technical solution, a multi-way connector is arranged between the feed pipe 10 and the static mixing component 20, one end of the multi-way connector is fixedly connected to the top of the static mixing component 20, and the other end is plugged into the bottom of multiple feed pipes 10.

[0033] Furthermore, in the above technical solution, a valve is provided inside the discharge pipe 30 in a direction away from the static mixing assembly 20 to prevent backflow inside the discharge pipe 30 to avoid blockage.

[0034] Furthermore, in the above technical solution, the static mixing component 20 is a cylindrical structure.

[0035] Furthermore, in the above technical solution, a plurality of baffles are fixed inside the static mixing component 20 . The baffles are staggered inside the static mixing component 20 and fixedly connected to the side walls of the static mixing component 20 .

[0036] Furthermore, in the above technical solution, the baffle is a sheet-like structure, and the baffle is inclined toward the flow direction of the flocculant, and the angle between the baffle and the side wall of the static mixing component 20 is 15-20°.

[0037] Furthermore, in the above technical solution, the discharge pipe 30 is a cylindrical straight pipe, and the diameter of the discharge pipe 30 is greater than the diameter of the feed pipe 10 .

[0038] Furthermore, in the above technical solution, the position where the multi-way connector is connected to the feed pipe 10 is bent in a direction away from the central axis of the multi-way connector.

[0039] Furthermore, in the above technical solution, metering pumps are provided on the multiple feed pipes 10 and the discharge pipes 30 .

[0040] Furthermore, in the above technical solution, the metering pump on the feed pipe 10 is used to extract different types of flocculants in proportion, and the metering pump on the static mixing component 20 is used to add a quantitative amount of mixed flocculants to the water pollution control pool.

[0041] Flocculant selection and dosing:

[0042] Different types of flocculants have specific mechanisms of action for different types of pollutants. For example, some flocculants can neutralize the charge in the water, causing suspended tiny particles to aggregate into larger clusters, which are convenient for subsequent sedimentation or filtration. The metering pump in the device is responsible for accurately controlling the dosage of each flocculant.

[0043] Feed pipe and static mixing:

[0044] The feed pipe delivers different types of flocculants to the static mixing component. The baffles inside the static mixing component are designed to be staggered and tilted. This design helps to increase the contact area and mixing effect between the flocculants, ensuring that the various flocculants can be fully mixed to form a uniform mixture.

[0045] Valve and discharge tube:

[0046] The discharge pipe is equipped with a valve to prevent the mixed flocculant from flowing back or getting blocked in the pipe, ensuring that the mixture is stably discharged to the water pollution prevention tank. This helps maintain the continuity and stability of the treatment process.

[0047] Optimization processing effect:

[0048] The mixed flocculants react with the target pollutants in the water pollution control tank to form large precipitates or clusters, which are convenient for subsequent separation or treatment. This method effectively improves the efficiency and effectiveness of water treatment by combining different types of flocculants and a precise mixing process.

[0049] Specifically, the principle of the utility model is: when in use, ensure that all flocculant storage tanks are filled with appropriate flocculants, and ensure that the feed pipes are properly connected to each storage tank; set the dosage of the metering pump according to the specific conditions of the treated water body and the results of the water quality analysis. The metering pump will automatically release the flocculant in the storage tank according to the preset parameters. When the metering pump is running, various flocculants will be pumped into the feed pipe. After entering the static mixing component, different types of flocculants will be mixed therein. The baffle inside the static mixing component helps ensure that the flocculants are evenly mixed. The mixed flocculants are output to the water pollution prevention and control pool through the discharge pipe. The valve in the discharge pipe prevents backflow and blockage, ensuring the normal output of the mixture. Regularly check and clean the flocculant addition device, especially the static mixing component and the discharge pipe, to prevent blockage and ensure the normal operation of the equipment.
