Introduction: The non-thermal adsorption dryer utilizes the characteristic that the adsorbent selectively adsorbs certain components, and adsorbs moisture in the compressed air to achieve the purpose of drying. Since the adsorbent is adsorbed to a certain time to reach a saturation equilibrium, it is necessary to regenerate with a dry gas to restore the adsorption drying ability. The non-thermal adsorption dryer uses a double tower to utilize a part of its own drying gas and depressurizes it to near atmospheric pressure, regenerates it as regeneration gas, and performs double-column switching at a fixed switching time to continuously supply dry gas. Micro-heat-drying machine combines the advantages of pressure swing adsorption and temperature-temperature adsorption, adsorption (working) at normal temperature and high steam partial pressure; analysis (raw) at higher temperature and low steam partial pressure, that is, adsorption of adsorbent during adsorption The water is completely removed during the regeneration process by the combination of thermal diffusion and low partial pressure of high quality reproduction (dry air heating). The adsorbed humid air enters the A dry tank from the lower pipe through the A1 valve, flows through the adsorbent bed from bottom to top, and the dried air is discharged from the upper pipe system. Regeneration/Blowing A small amount of dry air (about 7%) is decompressed by the upper pipe regeneration gas regulating valve and then heated to the heater. This part of the hot air (called regeneration gas) enters the B drying tank. The adsorbent in the B tank is analyzed and regenerated to restore the drying ability of the adsorbent, and the regeneration gas is discharged to the atmosphere through the lower pipe system B2 valve. After the regeneration of the pressure equalizing adsorbent is completed, the B2 valve is closed, and the B drying tank is gradually boosted to the online working pressure, ready to be switched. Switching the lower pipe system B1 valve is opened, the A1 valve is closed, the A2 valve is opened, the A and B drying tanks are switched, the B tank is sucked, and the A tank is discharged. The work sequence, working time and heating temperature are automatically controlled by the controller. Features: 1. Has a consistent and consistent outgassing pressure and dew point A. The height and diameter of the adsorption tower are accurately calculated by the experimental results, and the resistance of the tower bed is small, which ensures the contact time of the compressed gas desiccant for 5 seconds, and satisfies the dew point requirements of the finished gas. B. A 30% desiccant balance is used to compensate for the natural aging of the desiccant to ensure drying. C. Large diffuser ensures uniform airflow through the desiccant layer and eliminates channeling. 2. Regeneration gas loss is less than 14% A. Excellent barrel design saves 100% of the absorbed heat. The stored heat is used to increase the regeneration gas temperature during the regeneration phase, improving the desorption capacity of the equipment and making the regeneration more thorough. B. Drying and regeneration use a reverse convection scheme that works best when wet air flows through the dry adsorbent. The moisture content of the regeneration gas outlet is controlled in a sub-saturated state, so that the muffler and the exhaust passage have no condensation. C. The amount of regeneration gas can be adjusted according to the operating load demand of the dryer to ensure continuous and stable regeneration gas flow, and the regeneration pressure is as low as critical. 3. Desiccant has long service life A. The proper barrel size keeps the flow rate and time of the gas through the desiccant layer in an optimal state, giving full play to the performance of the desiccant. B. Reasonable system configuration, before the airflow enters the barrel, the high-efficiency degreasing treatment removes the oil and heavy pollutants in the airflow in time to avoid contamination of the desiccant layer. 4. The equipment adopts novel high-quality electric and pneumatic valves and advanced and reliable all-electronic programmable controller. The man-machine interface is friendly, and the two towers are automatically displayed continuously. The cycle can be programmed on site and the factory setting is 10min. The valve has a life of up to 500,000 movements. The inner wall of the cylinder is treated by cold galvanizing and anti-rust treatment, and it is not rusted for 10 years. 5.
