1. Core technical advantages of equipment
1.1 Technical analysis of twin tower adsorption type
Adsorption and switching mechanism: The dual-tower adsorption dryer of Hangzhou Risheng Purification Equipment Co., Ltd. is equipped with two pressure towers equipped with desiccant. When wet air enters one of the towers, the desiccant quickly acts as an adsorbent, capturing and fixing the water. Once the desiccant adsorbed water in the tower reaches saturation, the device automatically switches the valve in a very short time, allowing the wet air to enter the other tower for drying, ensuring the continuity of the drying process. This fast switching mechanism ensures the uninterrupted demand for dry air in industrial production and avoids production stagnation caused by drying interruptions.
Regeneration technical details: During the regeneration stage, the saturation tower undergoes either heating regeneration or decompression expansion regeneration. When heating and regeneration, Risheng accurately controls the heating temperature in the best regeneration temperature range of desiccant through the intelligent temperature control system. For example, for activated alumina desiccant, the temperature is usually controlled at 200-300 ℃, so that the water is fully evaporated and discharged. Vacuum expansion regeneration uses the principle of pressure difference to instantly reduce the pressure in the tower, promote the desorption of water in the desiccant, and then introduce a strictly filtered dry gas, the desorption of water thoroughly out of the dryer, so that the desiccant to restore adsorption vitality.
1.2 Highlights of rotary technology innovation
Unique structural design: Risheng's rotary dryer uses advanced adsorption technology, and its desiccant is closely combined with high-performance bonding materials with a unique honeycomb structure. This structural design greatly increases the contact area between the desiccant and the air, and the contact area is increased by more than 30% compared to the traditional granular desiccant. At the same time, it effectively avoids the problems such as uneven flow and wear of the inner wall of the equipment that may occur under the impact of the air flow, and greatly extends the service life of the equipment.
Continuous operation and energy saving advantages: The rotating drum is scientifically divided into multiple functional areas, usually 3/4 of the area for adsorption of humid air, 1/4 of the area for desiccant regeneration. As the rotating drum rotates at a constant speed, the adsorption and regeneration processes seamlessly and continuously alternate, eliminating the need to switch valves frequently, reducing the chance of failure. More importantly, the equipment cleverly uses the heat generated in the process of air compression to provide energy for regeneration, and through an efficient heat exchange system, the utilization rate of compression heat is increased to more than 85%, greatly reducing the energy consumption and operating costs of enterprises.
2. Practical application scenarios and results
2.1 Pipeline protection in the oil and gas industry
Pipeline corrosion risk analysis: In the oil and gas exploitation and transportation links, pipelines are exposed to complex environments for a long time. When the gas contains water, during the transportation process, the water will condense on the inner wall of the pipeline and chemically react with the acidic components in the natural gas (such as hydrogen sulfide, carbon dioxide, etc.) to form corrosive substances and accelerate pipeline corrosion. This corrosion will not only lead to the thinning of the pipe wall, reduce the pressure bearing capacity of the pipeline, but also may cause pipeline leakage, resulting in serious safety accidents and environmental pollution.
Application case: In a large natural gas transmission project, the pipeline of the project is thousands of kilometers long and passes through a number of regions with complex climates. Before the installation of Risheng's dryer, the pipeline needed to be repaired several times a year due to corrosion, which not only cost a lot of money, but also risked production disruption. After installation, continuous monitoring showed that the corrosion rate of the pipeline was reduced by more than 85%. This is thanks to the efficient dehumidification of Risheng dryer, which effectively avoids the erosion of water on the pipeline, greatly extends the service life of the pipeline, and reduces the high cost and production disruption risk caused by pipeline maintenance and replacement.
2.2 Response guarantee for the chemical industry
Sensitivity of chemical reactions to humidity: In the chemical industry, many chemical reactions are extremely sensitive to ambient humidity. In the production process of polyvinyl chloride (PVC), the polymerization reaction needs to be carried out in a dry environment. The presence of water will interfere with the normal progress of the reaction, and the reaction raw material side reaction, resulting in polymerization reaction out of control, making the product appear uneven molecular weight distribution, unstable performance and other problems, seriously affecting product quality and production efficiency.
Risheng dryer helps enterprises improve quality and efficiency: In a well-known PVC production enterprise, the company used to have a defective product rate of about 20% due to the humidity of the production environment. After the introduction of RISheng's dryer, the technical team of Risheng customized the dryer parameters according to the production process and needs of the enterprise to ensure a stable drying gas environment for polymerization reaction. After a period of operation, the product defect rate was reduced to less than 5%, and the product quality was significantly improved. This not only improves the market competitiveness of enterprises, but also saves a lot of costs caused by the disposal of defective products.
2.3 Precision assurance in the electronic manufacturing industry
Strict requirements for the air environment of chip manufacturing: In the field of electronic manufacturing, chip manufacturing, circuit board production and other links on the dryness and cleanliness of the air requirements are almost harsh. The lithography process in chip manufacturing needs to be carried out in an ultra-dry environment. Even a very small amount of water vapor may lead to the dissolution or deformation of the photoresist, which will affect the photolithographic accuracy, cause chip short circuit, electronic component failure and other problems, and seriously reduce the yield and performance of the chip.
Hangzhou Risheng Purification Equipment Co., Ltd. uses molecular sieve as a desiccant dryer, which can reduce the air dew point temperature to below -70 ℃, providing a stable and dry production environment for chip manufacturing. In an enterprise focused on high-end chip manufacturing, the chip yield increased from 80% to more than 90% after using Risheng's dryer. This is due to the super-strong adsorption capacity of the molecular sieve desiccant, which can deeply remove the water in the air, and the multiple filtration and purification technology is used inside the dryer to ensure that the output air is extremely clean, effectively avoiding the chip manufacturing defects caused by water vapor and impurities, and ensuring the high-quality production of electronic products.
2.4 Energy optimization of iron and steel metallurgy industry
The impact of compressed air humidity on energy utilization: In large-scale industrial production processes such as steel and metallurgy, compressed air is widely used in various equipment and processes. If the compressed air contains water, during transportation and use, the water will absorb heat, reduce the effective energy of the compressed air, and increase energy consumption. At the same time, moisture may also cause rust and wear inside the device, reducing the service life and operating stability of the device.
Energy saving effect: Hangzhou Risheng Purification Equipment Co., LTD., the compression heat regeneration dryer, the use of air compression process generated heat to regenerate the desiccant, energy utilization efficiency of more than 92%, greatly reducing the energy cost of enterprises. In a large steel enterprise, the annual energy consumption of the enterprise in compressed air drying is huge. After using the compression heat regeneration dryer of Sun Sheng, the compression heat can be fully utilized through the heat recovery system, and the annual energy cost can be saved up to millions of yuan. At the same time, due to the improved quality of the compressed air after drying, the equipment failure and maintenance costs caused by water are reduced, the operation stability of the equipment is improved, and the production efficiency is significantly improved.
