Description
Technical Field
The utility model relates to the technical field of air drying equipment, in particular to an energy-saving double-tower compressed air drying device.
Background
The device for compressing the gas is called a gas compressor, and the gas is compressed by the compressor and has higher pressure, which is equivalent to higher potential energy of the gas. However, since the gas compressor itself contains lubricating oil, a part of the lubricating oil is inevitably mixed into the compressed gas during the compression operation, and the air itself in nature also contains some solid particles, moisture, and the like, the compressed gas generated by the compressor is not pure. The direct use of such unpurified gas in the pneumatic circuit can cause the pneumatic circuit to fail, damage the pneumatic components, reduce the service life of the components, reduce production efficiency, and even cause accidents. According to statistics, more than 85% of failure stops of the pneumatic system are caused by using unclean and undried compressed gas, and as a result, the water in the compressed air can cause corrosion of components, and the components can be condensed and frozen in winter to cause blockage; oil and gas condensation and precipitation to form greasy dirt often cause ageing and failure of sealing elements; dust accelerates the abrasion of moving parts, causes blockage due to deposition, causes unnecessary pressure loss, and the like. Therefore, purifying these compressed gases to obtain pure compressed gases is an essential element in pneumatic systems.
Among these, the most influencing factors for pneumatic systems are the moisture contained in the compressed air. Moisture widely exists in the ambient air and cannot be completely removed, and after the moisture enters the compressor for compression, condensed water is separated out due to the change of temperature and pressure, so that the operation of a compressor unit and the performance life of other gas utilization equipment are seriously influenced, and the moisture in the air is quite necessary to be removed.
Drying is relative, i.e. air which is regarded as dry in certain demands, and still is regarded as not sufficiently dry in other applications. Therefore, what degree of drying is required for the compressed air to meet the neutralizing demand is a primary consideration when designing or selecting a dryer. Since a dryer is selected that does not require too low a dew point, procurement and operating costs will increase. According to the above several different theoretical methods, the compressed air drying methods developed and used at present mainly include the following:
(1) Adsorption drying method:
The adsorption drying method utilizes the adsorption performance of the adsorbent to moisture, such as silica gel, activated alumina, molecular sieve and the like, which have strong adsorption capacity to moisture, the moisture absorption process of the adsorbent is physical change and is renewable, and the adsorbent is adsorbed under high pressure and desorbed under low pressure, namely Pressure Swing Adsorption (PSA); or can be regenerated when heated under normal pressure, namely Temperature Swing Adsorption (TSA); or high-pressure normal-temperature adsorption and normal-pressure high-temperature desorption (PTC), and the dryness of the adsorption can reach the normal-pressure dew point of-70 ℃.
(2) Deliquescence drying method:
the deliquescent dryer also uses the adsorption property of the adsorbent to moisture, but the deliquescent adsorbent becomes liquid after adsorbing moisture and is discharged, so that the adsorbent after the passage cannot be regenerated and causes environmental pollution. This method is also known as chemical. Such dryers can reach dew points of around-38 ℃.
(3) Freeze drying method:
The freeze drying method is to cool the compressed air by utilizing the cold energy generated by the refrigerating compressor to make the compressed air reach the dew point temperature corresponding to the pressure of the compressed air, so that the water in the compressed air is separated out to achieve the drying purpose. The dryness of the drying method can reach the normal pressure dew point of-23 ℃.
(4) Membrane separation drying method:
Drying compressed air by membrane separation technology is a very promising drying approach. When the compressed air passes through the hollow fiber membrane, the osmotic pressure of the medium substances is different, so that water is separated from the compressed air, and the drying effect is achieved.
The existing compressed air drying method has the defects of high running cost, high consumption of adsorption materials, short service life of equipment and the like, and the drying effect of the compressed air drying method is difficult to meet the higher and higher gas consumption requirements of the equipment, so that a new method and a new path are needed to solve the problem.
