Description

Technical Field

[0001] The utility model relates to the field of dryers, in particular to a low dew point compression heat blast regeneration type dryer. Background Art

[0002] The adsorption dryer uses advanced chemical technology. Its principle is to use the difference in volume between water and air molecules to filter out saturated water vapor in the compressed air using a gas purification-specific molecular sieve. The water molecules can be easily adsorbed in the molecular sieve particles, and then the molecular sieve can be restored using a regeneration method. The dew point of the compressed air can easily reach -40°C.

[0003] Existing zero-gas consumption low-dew point compression heat adsorption dryers often use heat exchangers for heating. After the heating process is completed, the heat is directly dissipated, the energy utilization rate is low, and it does not conform to the concept of environmental protection.

When the hot water needs to be used, the drain valve 24 is opened to draw out the hot water.

[0005] When the above device is in use, the compression heat generated by the dryer is used to heat the connecting plates installed on the upper and lower sides of the heat storage jacket, and the high-temperature connecting plates are used to heat the water inside the heat storage jacket, so as to realize the recovery and utilization of the compression heat generated by the dryer; although the water can be heated by the compression heat and then utilized, the heat transfer area between the connecting plates and the water inside the heat storage jacket is small, the water cannot be heated quickly, and the heat utilization efficiency is low.
