Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically a hybrid energy-saving dryer. Background Technology

[0002] With the development of industrial production, the demand for high-quality compressed air is increasing. Compressed air contains a certain amount of water vapor, which, if not effectively dried, will affect the normal operation of air-using equipment, shorten its service life, and even lead to product quality problems. Refrigerated compressed air dryers are a commonly used dehumidification device. They use refrigerant circulation to cool compressed air to below the dew point temperature, condensing the moisture in the humid air to obtain dry air.

[0003] In the operation of refrigerated compressed air dryers, compressors are usually used for refrigeration. Since the temperature of compressed air is often relatively high, the compressor needs to have high power to meet the condensation and cooling requirements. This not only results in high energy consumption, but also relies on refrigerants such as Freon, which is not conducive to ecological protection. Furthermore, it is prone to high temperature shutdown and ice blockage problems, leading to poor working stability. Therefore, a hybrid energy-saving dryer is proposed. Utility Model Content

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0015] 1. This dryer differs from the traditional pure compression refrigeration structure. It adopts a combination of ambient temperature circulating water and chilled water with an auxiliary circulating cooling system. Relying on water to provide the cold source not only greatly reduces energy consumption but also completely solves the problems of high-temperature shutdown and ice blockage in traditional refrigerated dryers. Moreover, the equipment's compressor refrigeration system is only activated during the high-temperature weather from May to December throughout the year, and the compressor's start-up time is only half of the total daily time. The annual energy consumption of the whole machine is only about 10% of that of traditional refrigerated dryers.

[0016] 2. The device relies on water heat exchange for operation, which has less limitation on environmental requirements and can be used in most harsh environments. The internal heat exchange tubes are all made of stainless steel, which is corrosion resistant, has a long service life, and has a low failure rate. In addition, the entire device is detachable, which is convenient for cleaning, maintenance and upkeep.

[0017] 3. The uniquely designed pre-cooling and reheating device ensures that the saturated hot compressed air entering the dryer undergoes three cooling and one heating process, resulting in dry compressed air with very low absolute moisture content and relative humidity at the dryer's exhaust port. This results in a small pressure difference, saves air compressor energy, and automatically adjusts water and air temperatures according to environmental changes, maintaining the dew point temperature within the normal range.

[0034] Working principle or structural principle:

[0035] Step 1: The high-temperature, humid, saturated compressed air produced by the air compressor enters the reheater 1. Inside the reheater 1, it exchanges heat with the cold air that has been cooled twice by the secondary cooler 3 through the first heat exchange tube 8, so that the hot compressed air about to enter the primary cooler 4 is initially cooled down and the discharged cold air is heated up.

[0036] Step 2: The compressed air, which has been initially cooled in the reheater 1, enters the first-stage cooler 4 to exchange heat with the ambient temperature cooling water. The cooling water carries away the heat from the compressed air, causing the compressed air temperature to drop. The gaseous water molecules in the compressed air reach the saturation temperature and condense into liquid water. Most of the condensed liquid water is discharged through the two drain ports at the bottom of the first-stage cooler 4.

[0037] Step 3: Another small portion of liquid water enters the secondary cooler 3 with the gas and exchanges heat with the ice water to cool the compressed air a second time. This lowers the temperature of the compressed air, and the gaseous water molecules in the compressed air reach the saturation temperature and condense into liquid water. The condensed liquid water is discharged through the two drain ports at the bottom of the secondary cooler 3. After being cooled a second time by the secondary cooler 3, the gas enters the filter 2 and is separated and filtered by the filter element 22 and the core plate 27 before being automatically discharged from the drain port at the bottom.

[0038] Step 4: After cooling and dehydration, the cold air flows back into the reheater 1 to exchange heat with the high-temperature compressed air input from the outside. The cold air that has undergone heat exchange has its temperature increased due to heat absorption, changing from a saturated state to an unsaturated state, so that the air will not precipitate liquid water due to temperature drop during pipeline transportation.

[0039] In summary, this dryer differs from traditional pure compression refrigeration structures. It employs a combination of ambient temperature circulating water and chilled water with an auxiliary circulating cooling system. Relying on liquid water as the cold source not only significantly reduces energy consumption but also completely solves the high-temperature shutdown and ice blockage problems of traditional refrigerated dryers. Furthermore, the compressor refrigeration system is only activated during the high-temperature weather from May to December, and the compressor's operating time is only half of the total daily time. The overall annual energy consumption of the machine is only about 10% of that of traditional refrigerated dryers. The device relies on water-based heat exchange, which has fewer environmental limitations and can adapt to most harsh environments. The internal heat exchange tubes are all made of stainless steel, which is corrosion-resistant, has a long service life, and a low failure rate. The entire device is detachable, facilitating cleaning and maintenance. It adopts a uniquely designed pre-cooling and reheating device, which ensures that the saturated hot compressed air entering the dryer undergoes three cooling and one heating process before reaching the dryer's exhaust port, resulting in dry compressed air with very low absolute moisture content and relative humidity. The pressure difference is small, which saves air compressor energy consumption. Moreover, it can automatically adjust the water temperature and air temperature according to environmental changes, maintaining the dew point temperature within the normal range.
