(1)What is dew point temperature (Td)?

        Characterization of the degree of dryness of the humidity unit, refers to the air in the water vapor saturated water began to condense the temperature, that is, when the temperature of condensation. At 100% relative humidity, the ambient temperature is equal to the dew point temperature. The smaller the dew point temperature to the ambient temperature, condensation may mean smaller, which means more dry air.Dew point not affected by temperature, but by the pressure.

(2)Drying method for compressed air?

         In order to solve the problems caused by excessive moisture, a variety of principles of drying equipment came into being, and was used for air pressure.

Machine equipment supporting. There are two basic compressed air dryers: a freeze dryer and an adsorption dryer.

      Frozen dryers are often used to remove excess moisture from compressed air. It is through the use of refrigeration systems and different.

      Of the heat exchanger to reduce the compressed air temperature to +2 ... +5C, (air dew point temperature), then the air too much water is condensed after the exclusion, after the gas is heated back to room temperature. The freeze dryer is controlled by measuring the freezing temperature, but it is usually necessary to measure the dew point to ensure that the dryer is working properly.

      The adsorption dryer dries the moisture through the desiccant to dry the gas. The most commonly used desiccant is silica gel, activated alumina, molecular sieves. Adsorption drying method is usually higher than the freeze-drying efficiency, adsorption drying method can be dry to 40 ° C dew point temperature, if the molecular sieve and silica gel or activated alumina can be used in conjunction with -100.C dew point temperature. The adsorption dryer usually consists of two drying towers filled with desiccant and through the valve to control the flow of compressed air in both drying towers. The drying process and the regeneration process are carried out. During the drying process, the compressed air flows from a drying tower under pressure, and when the gas flows through the desiccant, the microvoids on the surface of the desiccant adsorb the moisture in the air. For the regeneration of desiccant, usually a variety of design, usually by heating the desiccant in the absorption of water to remove, to restore water absorption capacity.

(3) Dew point measurement can save energy better.

        According to statistics, the factory about 10% of the energy consumption is used to produce compressed air reliable dew point measurement can accurately control whether the dryer is working within the technical indicators. For desiccant desiccators, the regeneration interval can be controlled by measuring the dew point and saving a lot of energy for the user. Unlike conventional timer methods, the system does not start the regeneration function as long as the degree of compressed air is within the range required by the user. Dew point control can be for the user.Saving up to 80% of the energy costs.

(4) How does water in compressed air form?

        As the compressor compresses the air, the dew point of the compressed gas rises, and at some point the moisture in the gas reaches saturation and begins to condense. For example, a 30-kilowatt compressor can produce about 20 liters of liquid water at 8 hours of operating time when compressing air at 20.C, 60% RH.

(5) What is the generation of compressed air?

      The air compressor to do the mechanical movement to reduce the size of the air after the pressure is called compressed air. Compressed air is an important power source, with: pollution-free, clear and transparent, easy to transport, no harmful performance, no fire risk, etc., therefore, is widely used in all aspects of production enterprises. For example, the operation of the processing machinery, the transmission and control of the pneumatic valve, the cylinder and the controller, the transmission medium or the purge gas. In order to obtain dry, clean, oil-free, meet the requirements of clean compressed air, it must be purified. The filtration system can remove the oil and dust, and the water is dehydrated by the dryer.
