  • Combined low dew point dryer

    Combined low dew point dryer

    Working principle of the combined low dew point dryer: The combined low dew point dryer is composed of a cooling dryer and an adsorption (no heat or heat) dryer through reasonable pipeline connection and volume matching. Cooling dryers have extremely strong water removal capacity, low operating energy consumption, and no loss of air volume. Combined with the characteristics that adsorption dryers can reach lower dew points, the advantages of both can be used to the limit. Before the compressed air enters the adsorption dryer, use a cooling dryer to perform pre-treatment, so that a large amount of water (about 80%) is first removed in the refrigerated dryer. After entering the adsorption dryer for deep drying, it can A very low pressure dew point is reached, up to -70 ° C. It uses a freeze dryer as a pre-water removal device for an adsorption dryer. The strong water removal capacity of the refrigerating dryer drastically reduces the inlet water load of the drying tower. After cooling, the water entering the adsorption tower is about 20% of the ordinary dryer. Under other conditions, it is used for absorption. Low dew-point dry air with water vapor can also decrease by the same magnitude. That is, the amount of regeneration gas is about 1/5 of that of ordinary adsorption dryers.

  • Blast heat regeneration adsorption dryer

    Blast heat regeneration adsorption dryer

    Working principle: The blast regeneration adsorption dryer is an energy-saving compressed air drying device. It adopts the process of ambient air blast regeneration, so it can save a lot of product gas required for traditional process regeneration. The basic principle of adsorption by the blast regeneration adsorption dryer is similar to the traditional adsorption process. However, the regeneration method is a blast regeneration process, and the process steps include heating and cooling. During heating, the regeneration gas source comes from the ambient air boosted by the blower, and is heated to the regeneration temperature by the heater as the regeneration gas analyzed by the adsorber bed. During the regeneration operation, the regeneration heating gas performs heating analysis on the adsorption bed, and the regenerated gas carries the precipitated water vapor and takes it out of the adsorber. Regenerative blown or taken from its own dry air, after decompression, used as regenerative blown cold gas, or air circulation cooling separation as regenerative blown cold gas, blown cooling the bed to meet the needs of adsorption work in the following stages, and avoid air outlets The dew point is unstable due to the presence of bed temperature. Work flow: The blower sucks in the external air for a closed cycle, no compressed air loss is needed during the entire regeneration process. The automatic operation is continuous, and there is no compressed air loss during the entire regeneration process. The pneumatic butterfly valve uses high temperature resistant materials to effectively reduce the system pressure drop. Adsorption process Bottom right up to ensure dryness of the gas at the outlet end. Compressed air contains a large amount of water vapor from the air inlet into the adsorption tower, and then diffuses into the adsorption bed. The water vapor in the air is absorbed by the desiccant during the inflow process, and the dried air enters the pipe network for use through the outlet. Heating regeneration stage: One tower is adsorbed while the other tower is regenerating. The regeneration process first regenerates the pressure in the tower to the normal atmospheric pressure through the regeneration valve. Ambient air is used for reconditioning. First, the ambient air is sucked into the blower to be pressurized to the regeneration pressure. Due to the compression principle, the temperature of the regeneration gas will also increase, which reduces the load on the heater. Then the heater heats the air to the regeneration. Temperature, under the constant action of the blower, hot air flows into the adsorption bed. The desaturation and evaporation of hot air are used to regenerate and dry the adsorption bed. Cold blowing phase; after the end of the regeneration heating process, the ambient air is also used for cold blowing. This unique cold blowing method uses a closed water cooling system and forms a closed circulation system through the combined action of the valve. The fan is used as a power cycle The driving force enables the hot air of the adsorption tower to continuously exchange heat with the water cooler. The cooled air enters the adsorption tower and takes away the heat of the adsorbent, which is the best effect of reducing the temperature of the adsorbent. This achieves zero air Consume regeneration. Structural features: 1. In order to ensure that the flow rate of compressed air passing through the drying tower is slow and the flow through the cross section of the tower body is uniform to effectively prevent the "short circuit" phenomenon, we use the air diffuser in the adsorption tower of the blast heat regeneration adsorption dryer. Different special designs were carried out. 2. The scientific and reasonable design of the structure of the adsorption tower fully guarantees the ideal empty tower flow rate of 0.2 to 0.3 m / s, so that the contact time between compressed air and the adsorbent is not less than 5.5 seconds, to achieve complete adsorption of moisture, sufficient cooling, and ensure dryness. Machine dew point is stable. Avoiding the movement of the adsorbent, thereby reducing the possibility of liquefaction and pulverization of the adsorbent, enhancing the reliability of the blast heat regeneration adsorption dryer, and extending the life of the adsorbent, which can be as long as 5 years. This design philosophy of keeping facts realistic is not available to many domestic counterparts. 3. The reverse convection scheme is adopted for the drying gas and regeneration gas, because the unused part of the adsorbent in the adsorption bed does not need to be desorbed. The reverse flow of the regeneration gas can make the residual load at the end of the adsorption bed low, and maintain high drying during the next cycle of adsorption Degree is more favorable. 4. The exhaust muffler of the dryer can be arranged outdoors, the muffler works well, and the noise at a distance of 1 meter from the equipment is less than 80dB (A).
