The waste heat regeneration air dryer absorbs the advantages of high-temperature desorption of thermal adsorption dryers and the large adsorption capacity of non thermal adsorption dryers at room temperature, avoiding the disadvantages of short switching time and high regeneration gas consumption of non thermal adsorption dryers. It also overcomes the disadvantages of high power consumption of thermal adsorption dryers. It utilizes the high exhaust temperature of air compressors to regenerate and dehydrate adsorbents, and adopts the principle of temperature and pressure swing adsorption to dry compressed air. Suitable for air compressors with exhaust temperatures above 110 ℃.

Working principle of waste heat regeneration air dryer

The waste heat regeneration adsorption air dryer is currently a relatively advanced regeneration adsorption air dryer, which flexibly uses the heat generated by the high-temperature exhaust of the air compressor to promote the heating and regeneration of the adsorption desiccant, changing the traditional electric heating method and reducing energy consumption. The working principle of the waste heat regeneration dryer is similar to that of pressure swing adsorption. In this process, the adsorbent is mainly used to adsorb moisture in the air for regeneration. The high-temperature gas (>110 ℃) from the air compressor is used to enter the drying tower for thermal diffusion, and then the regenerated gas is used to bring water vapor out of the drying tower, achieving the ultimate goal of thoroughly removing the existing moisture.

Although the waste heat regeneration air dryer has a wide range of applications, it also contains a lot of knowledge points. Firstly, you need to know that the waste heat regeneration air dryer has a well-designed adsorption tower body, high-performance activated alumina adsorbent, and good muffler. In addition to these, it is also due to its unique imported pneumatic controller, which has high power and durability. Regenerated gas regulating valve for precise flow control. In fact, according to the heating method, it can be divided into various types such as convection, conduction, radiation, dielectric, etc. Convection dryer, also known as direct dryer, uses a hot drying medium to directly contact wet materials, transferring heat through convection and carrying away the generated steam; Conductive dryer is also known as indirect dryer. It transfers the heat from the heat source to the wet material through a metal partition in a conductive manner, and the generated water vapor can be removed by vacuum suction, a small amount of gas blowing, or condensation on a separate low-temperature condenser surface. This waste heat regeneration air dryer does not use a drying medium, which naturally increases its thermal efficiency and does not pollute the product. However, its drying capacity is limited by the heat transfer area of the metal wall, and its structure is also relatively complex, often operated under vacuum; Simultaneously using various radiators to emit electromagnetic waves within a certain wavelength range, which are selectively absorbed by the surface of wet materials and then converted into heat; The thermal effect occurs inside the wet material.

The waste heat regeneration air dryer adopts a high-performance evaporator with a large heat exchange area, small heat transfer temperature difference, and more stable outlet air temperature of the evaporator. Adopting an efficient gas water separation structure, the oil-water separation efficiency is high. I suggest that you go for inspection after receiving it. For example, after the arrival of new equipment, the equipment management department, together with the purchasing unit and the using unit (or the receiving unit), conducts an open box inspection to check whether there are any defects in the equipment during transportation. The waste heat regeneration air dryer has no damage, loss, accessories, or random spare parts. In this case, you can use special tools, technical materials, etc. to ensure compliance with the contract. The packing list is complete, fill out the equipment unpacking acceptance form, and store it in the equipment file. If there are defects or non conformities, relevant units should be consulted immediately to make demands or claims. In addition, the waste heat regeneration air dryer is also marked and positioned according to the equipment process plan and installation construction drawings, foundation drawings, equipment external dimensions, and mutual distance drawn by the process technology department, organizing foundation construction and equipment transportation in place. Of course, it is also necessary to adapt to the needs of the process flow, facilitate the storage, transportation, and on-site cleaning of workpieces. Our company’s products can certainly meet these needs, and we welcome long-term cooperative relationships with friends from all over the country. After all, it is well-known in this industry, with reasonable prices and guaranteed quality. You will definitely not be disappointed.
