[0028] In order to make the above-mentioned purposes, characteristics and advantages of the present application more apparent, obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0029] In the field of water treatment, pharmaceutical mixing equipment plays a crucial role. Its performance directly affects the water treatment effect, and is related to the purification quality and reuse efficiency of water resources. The following will introduce in detail several common pharmaceutical mixing equipment for water treatment.

[0030] 1. Static mixer

[0031] Structure and principle: Static mixer is a device with exquisite structure, which is mainly composed of a series of fixed mixing units arranged in order. The shapes of these mixing units are various, common ones include twisted blades, perforated plates full of small holes, or other carefully designed unique shapes. When the water to be treated and the medicine flow into the static mixer at the same time, a wonderful mixing journey begins. In the process of flowing through the mixing units, water and medicine are continuously divided and recombined. In this process, the shearing, diffusion and convection of the fluid are fully utilized. The shearing effect of the fluid is like an invisible scissors, which cuts larger fluid blocks into smaller parts; the diffusion effect promotes the gradual uniform distribution of drug molecules in water, like ink slowly bleeding in clear water; and the convection effect makes different regions of the fluid exchange positions, further accelerating the mixing process. It is through the synergistic effect of the three actions that water and medicine can be uniformly mixed.

[0032] Features: Static mixer has many obvious advantages. First, since there are no moving parts inside, the maintenance cost of the equipment is greatly reduced. There is no need to frequently replace the wearing parts, and there is no need to worry about equipment failure due to part wear, greatly reducing the maintenance workload and frequency. Second, its structure is very simple, without complex mechanical structure, which not only makes the manufacturing cost of the equipment relatively low, but also occupies a very small area. For water treatment plants with limited space, it is undoubtedly an extremely attractive choice. Thirdly, in terms of mixing effect, static mixer can preliminarily mix medicine and water uniformly in a relatively short time, meeting the preliminary mixing needs in general water treatment process.

[0033] Application scenario: Given its characteristics, static mixers are often used in water treatment scenarios where the mixing effect is not extremely demanding and the flow is relatively large. For example, in the preliminary dosing mixing link in a municipal sewage treatment plant, a large amount of sewage needs to be quickly and preliminarily mixed with chemicals, and a static mixer can efficiently complete this task, laying a good foundation for subsequent deep treatment processes.

[0034] 2. Agitated mixing equipment

[0035] Structure and principle: Agitated mixing equipment is mainly composed of key components such as agitators, tanks, motors, etc. The agitator rotates at high speed under the driving force of the motor output, like a powerful stirring rod, creating intense agitation in the liquid in the tank. The types of agitators are diverse, with common paddle agitators like oars that can generate large circulating flows in the liquid, suitable for situations where the mixing requirements are relatively low and the liquid viscosity is small; turbine agitators are known for their powerful shearing force, which can fully break up and mix chemicals and water, suitable for situations where mixing is difficult and high shearing force is required; anchor agitators are often used to handle high-viscosity liquids, with a shape that can closely adhere to the bottom of the tank, effectively preventing material from accumulating at the bottom. When the agitator rotates, the water and chemicals in the tank are subjected to strong agitation by the agitator, causing the chemicals to disperse rapidly in the water and achieve uniform mixing.

[0036] Features: Agitated mixing equipment excels in mixing performance. Operators can flexibly adjust the stirring speed and time according to actual needs. For some water treatment processes that require extremely high mixing performance, such as the need to accurately control the reaction degree of chemicals and wastewater in some industrial wastewater treatment, by adjusting the stirring parameters, it can ensure that the chemicals and water are fully mixed to meet complex mixing requirements. In addition, it can also handle high-viscosity liquids and chemicals containing solid particles, showing strong adaptability. However, its operation process consumes a certain amount of electrical energy, and since there are moving parts, the motor, agitator, and other components need regular maintenance to ensure stable operation of the equipment.

[0037] Application scenario: Agitated mixing equipment, with its excellent performance, is widely used in water treatment plants of various scales. In the field of industrial wastewater treatment, especially in the coagulation and sedimentation link, due to the complex composition of industrial wastewater and the large differences in water quality, it is necessary to accurately control the mixing effect of chemicals and wastewater, and agitated mixing equipment can perform well, ensuring that coagulants and other chemicals fully react with wastewater to achieve efficient solid-liquid separation.

[0038] 3. Jet mixer

[0039] Structure and Principle: The working principle of the jet mixer is based on the unique characteristics of high-speed jets. It utilizes a high-pressure water stream through a carefully designed nozzle to generate a high-speed jet. This high-speed jet acts like a powerful "water gun" and creates a distinct negative pressure zone around it. When the drug is within the range of this negative pressure zone, it is quickly sucked in and thoroughly mixed with the high-speed jet water. At the same time, there is a strong interaction between the jet and the surrounding water, resulting in turbulent flow phenomena. This turbulence further promotes the mixing of the drug and water, allowing the drug to be uniformly dispersed in the water within a short period of time.

[0040] Features: The jet mixer has extremely high mixing efficiency and can mix drugs and water very uniformly within a very short period of time. Moreover, it does not require additional complex stirring equipment and can achieve high-efficiency mixing solely through its own jet structure, making its structure relatively simple and its manufacturing cost relatively low. In addition, the operator can flexibly adjust the pressure and flow of the jet according to the actual mixing requirements. By changing these parameters, it can adapt to different drug addition amounts, water quality conditions, and mixing requirements, showing good flexibility.

[0041] Application Scenarios: In the disinfection process of drinking water treatment, the jet mixer has a wide range of applications. For example, when adding disinfectants to water, it is necessary to ensure that the disinfectants can be quickly and uniformly mixed with water to achieve good disinfection effect. The jet mixer can meet this demand and accurately mix disinfectants into water to ensure the microbial safety of drinking water. At the same time, in some water treatment processes that require high mixing speed and relatively small drug addition amount, the jet mixer can also demonstrate its unique advantages.

[0042] 4. Pipe Mixer

[0043] Structure and Principle: The pipe mixer is a mixing device that is closely integrated with the pipe system. It is generally installed inside the pipe system and achieves mixing by cleverly setting special mixing elements in the pipe. The design of these mixing elements aims to utilize the flow characteristics of the fluid in the pipe, by changing the flow rate, flow direction, etc., to promote the gradual mixing of the drug and water in the flow process. When water and drugs enter the pipe equipped with a pipe mixer, the mixing elements will perform operations such as splitting, turning, and merging on the fluid, allowing the drug and water to gradually mix uniformly in the constantly changing flow field.

[0044] Features: The biggest advantage of the pipeline mixer is its high integration with the pipeline system. It does not require additional space and does not have a significant impact on the existing water treatment plant layout, and can be well integrated into the existing pipeline network. During operation, the mixing process is continuous and stable, and is very suitable for large-scale water treatment systems. In large-scale water treatment processes, a large amount of water and drugs can be continuously and stably mixed in the pipeline, providing stable mixed liquid for subsequent treatment processes. However, the pipeline mixer has certain requirements for the arrangement of the pipeline and the water flow rate. It is necessary to reasonably design the layout, pipe diameter and water flow rate of the pipeline to ensure the best performance of the mixing effect.

[0045] Application scenarios: In the pipeline transportation process of large-scale water treatment plants, the pipeline mixer plays an important role. For example, when adding flocculants and other drugs to the water pipeline network in a water treatment plant, the pipeline mixer installed in the pipeline can simultaneously complete the mixing of the drugs during water transportation, achieving efficient and convenient water treatment operation and ensuring that the quality of the water leaving the plant meets the standard.

[0046] Different types of water treatment drug mixing equipment have their unique advantages and application scenarios. In actual water treatment engineering, it is necessary to consider various factors such as water quality, treatment scale, mixing requirements, and cost budget to select the most suitable mixing equipment to ensure efficient and stable operation of the water treatment process and achieve high-quality purification and rational use of water resources.
