What are the drying purposes and advantages of a zero-air-consumption regenerative adsorption dryer?
Currently, the waste gas from the regeneration process of existing heat recovery adsorption dryers is directly discharged. This waste gas contains a certain amount of thermal energy. Direct discharge not only wastes energy but also exacerbates the greenhouse effect and damages the environment. Currently, addressing the shortcomings of dryers on the market where waste gas from the regeneration process is directly discharged into the atmosphere, which wastes energy and damages the environment, a gas-free regenerative adsorption dryer is provided. It recycles the waste gas from the regeneration process back to the inlet for reuse, thus achieving zero consumption of compressed air during the drying process, saving on the manufacturing cost of compressed air, and protecting the environment.
gas-free regenerative adsorption dryer It is a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects. For the use or further processing of materials, the moisture in the materials is evaporated and escapes through heating to obtain solid materials with a specified water content. The drying process consumes a large amount of heat energy. In order to save energy, some materials with high water content, suspensions or solutions containing solid substances are usually first mechanically dehydrated or heated and evaporated, and then dried in a gas-free regenerative adsorption dryer to obtain dry solids.
The purpose of drying is to meet the needs of material use or further processing. For example, drying wood before making wood molds and wood products can prevent product deformation, while drying ceramic blanks before calcination can prevent cracks in the finished product. In addition, dried materials are also easier to transport and store. For example, harvested grains are dried below a certain water content to prevent mildew. Because natural drying is far from meeting the needs of production development, various mechanized gas-free regenerative adsorption dryer applications are becoming increasingly widespread.
So, what are the performance advantages of a gas-free regenerative adsorption dryer?
1. Reasonable adsorption tower design
A large adsorption bed with a contact time of 6.25 seconds ensures that the saturated air entering the dryer is dried to the dew point required by the adsorption dryer and compensates for the natural aging of the adsorbent layer;
Appropriate tower diameter and upstream drying and downstream regeneration convection methods are conducive to reducing the amount of regeneration gas, avoiding fluidization of the adsorbent and contamination of the adsorption layer;
A slow and complete pressurization procedure and delayed switching design can eliminate pulsations in the downstream airflow, preventing the movement and wear of the adsorbent;
Independent filling and discharge ports facilitate the replacement of the adsorbent;
A reliable large stainless steel diffuser ensures that the airflow passes uniformly through the adsorption layer, eliminating channeling;
The manufacture of the tower body should comply with national pressure vessel standards and specifications.
2. High-performance activated alumina adsorbent
High compressive strength, wear resistance, high temperature resistance, non-hydrolysis; large static adsorption capacity.
3. Good silencer effect
Symmetrical setting to weaken the noise superposition effect;
Specialized pressure relief box, easy to disassemble the silencer, good silencing effect.
4. Large power, durable pneumatic controller for the inlet
Using a two-position five-way pilot valve and control gas after deep drying filtration to ensure accurate control;
Double piston structure, large pneumatic power, reliable action, fast response;
The controller is isolated from the main airflow to avoid moisture and air pollution.
