Liquid distributor is a fluid distribution equipment widely used in industries such as chemical, petroleum, and pharmaceutical. It can effectively distribute fluids evenly into various branch pipelines through design and working mechanisms, thereby ensuring the stability of the production process and product quality. 1、 Working mechanism The trough distributor is mainly composed of trough, distribution pipe, connectors, and other parts. Its working principle is to use the fluid dynamics principle inside the trough to introduce fluid from the main pipeline into the trough, and then evenly distribute it to each branch pipeline through the distribution pipe. Specifically, when the fluid enters the trough, a certain flow velocity and pressure distribution will be formed inside the trough. Due to the shape and structural design of the groove disk, the fluid will generate rotation and vortex effects inside the groove disk, making the fluid more evenly distributed inside the groove disk. Subsequently, the fluid flows into each branch pipeline through the distribution pipe, achieving uniform distribution of the fluid. 2、 Application advantages Uniform distribution: It can effectively distribute fluid evenly to each branch pipeline, avoiding production instability and product quality problems caused by uneven fluid distribution.

Polyhedral hollow ball are processed from polypropylene (PP). Mainly used for the removal of gases such as oxygen, chlorine, carbon dioxide, etc. in cooling towers and purification towers. The appearance is spherical, with main specifications including φ 25mm, φ 38mm, φ 50mm, and φ 76mm. Multi sided hollow spheres can purify water quality and meet national standards when used for sewage treatment. It mainly plays a role in gas-liquid contact, achieving heat and mass transfer. Increasing the area of gas-liquid contact inside the tower is an important component that affects the heat and mass transfer of the tower.   Polyhedral hollow ball is a type of filler made of plastic with a spherical appearance. It is composed of two hemispheres, each with 12 blades in a semi fan shape. The upper and lower blades of the two hemispheres are offset from each other. This type of packing structure has the advantages of high gas velocity, low resistance, large specific surface area, and high operational elasticity. However, due to the large number of blades in the multi-faceted hollow sphere, there is a shielding effect between them, which is not conducive to the distribution and wetting of liquids. Most liquids gather in the hollow column of the sphere, which affects the smoothness of gas flow. Polyhedral hollow ball are injection molded, while ordinary fillers are made of polyethylene plastic. This biological filler is extremely beneficial for the attachment and growth of microorganisms inside the filler, and the biofilm produced is relatively stable, making it prone to fluidization. 

Tri pack is a functional product or device that combines environmental protection concepts and technological innovation, aimed at reducing environmental pollution, improving resource utilization efficiency, or promoting ecological protection. The original intention of its design is to solve environmental problems in daily life or industrial scenarios through simple and reusable methods. Environmentally friendly ball fillers play various key roles in environmental engineering, which can be further divided into the following aspects: 1、 Physical effects Increase contact area Porous structure design (such as honeycomb or corrugated) significantly increases the gas-liquid or liquid-liquid contact area, promoting mass transfer efficiency. For example, in an absorption tower, the contact area between exhaust gas and treatment solution can be increased by 3-5 times. 2、 Biochemical action Biofilm carrier   The specific surface area can reach 800m ²/m ³, providing attachment space for microorganisms such as nitrifying bacteria. A case study of a sewage treatment plant shows that the use of environmentally friendly balls increases the thickness of the biofilm by 2 times and increases the removal rate of ammonia nitrogen by 35%.         Environmentally friendly balls made of different materials (such as PP, PVC, ceramics) are suitable for specific scenarios, and the selection should take into account factors such as pollutant properties, operating temperature, and cost. With the development of surface modification technology, new environmentally friendly balls are evolving towards functionalization (such as magnetism and photocatalysis) and intelligence (such as load sensors

Introduction to Stainless Steel pall Ring Packing: Metal pall Ring is an efficient packing widely used in chemical, environmental protection, refining and other fields. Its design and performance make it an important filling material in tower interiors. Below, we will provide a detailed explanation of the metal ball ring from the aspects of structural characteristics, application cases, and performance data.   The structural characteristics of stainless steel pall rings: Metal pall rings are a new type of filler designed and improved based on traditional Raschig rings. It adopts a double-layer wall structure, with multiple uniformly distributed windows on the ring wall. These windows not only increase the specific surface area of the packing, but also improve the mass transfer efficiency between gas and liquid. At the same time, the height to diameter ratio of the metal ball ring is usually controlled within a certain range. This design enables the packing to form a more uniform distribution inside the tower, reducing short circuits and wall flow phenomena in the airflow.   Application case of stainless steel pall rings: In the chemical industry, metal pall rings are widely used inside various towers, such as absorption towers, distillation towers, extraction towers, etc. Taking the distillation tower of a large refinery as an example, the tower originally used traditional Raschig rings as packing, but during operation, it was found that the purity of the product at the top of the tower could not meet the design requirements. Later, the factory decided to use metal ball rings to renovate the tower. After the renovation, the purity of the tower top product has been significantly improved, and the pressure drop inside the tower has also been significantly reduced, thereby improving the energy efficiency of the entire production process. In addition, metal ball rings also play an important role in the wastewater treatment process in the field of environmental protection. A certain sewage treatment plant used metal Bao'er rings as the packing material for the bioreactor when treating industrial wastewater containing high concentrations of organic matter. Due to its excellent mass transfer performance and large specific surface area, metal Bao'er rings provide a favorable environment for the growth and reproduction of microorganisms. After a period of operation, the wastewater treatment efficiency of the factory has been significantly improved, and the effluent quality has reached the national discharge standards.    

The specifications of ceramic corrugated structured packing are divided into 700Y, 450Y, 350Y, 250Y, 150Y, etc. Different specifications correspond to different product dimensions in terms of length, width, and height.   When consulting ceramic corrugated structured packing, customers generally want to know the specific surface area, bulk density, porosity, inclination angle, pressure drop, theoretical plate number, hydraulic diameter, liquid load, factors and other parameters of different types of products. The length, width, and height parameters, even for the same type of ceramic corrugated filler, have different sizes. The tower diameter varies under different operating conditions, and the required length, width, and height are also different.   The function of ceramic corrugated structured packing Due to the unique structure of ceramics, they have good hydrophilicity. The extremely thin liquid film and inclined and tortuous airflow channels can promote the flow of airflow without blocking it, making ceramic fillers compatible with metal fillers. However, their corrosion resistance and high temperature resistance cannot be compared with metal fillers. The surface structure has good wettability, which can accelerate the flow of liquids and minimize the amount of retained liquid in the filler. Thereby reducing the chances of overheating, polymerization, and coking.   The different inclinations can be divided into X-shaped and Y-shaped. X-shaped inclination angle of 300, Y-shaped inclination angle of 450. The X-type pressure drop is relatively small, while the Y-type mass transfer performance is good. To balance pressure drop and mass transfer performance, holes can be opened on the plate. Due to the lack of significant amplification effect of regular packing, its surface roughness is superior to the unique corrosion resistance of the material, and it is used in mass transfer processes such as distillation, stripping, absorption, and extraction in petrochemical industry. Have you learned about the length, width, and height specifications of ceramic corrugated regular packing through the above introduction
