Let's explore some of the working principles of waste heat recovery dryers?
2022-07-28
Waste heat regenerative dryers utilize the high-temperature thermal energy from the second-stage exhaust of an air compressor, or uncooled high-temperature compressed air, for deep desorption and regeneration of the adsorbent. This eliminates the need for external heat sources. To help you understand it better, here's an explanation of the working principles of a waste heat regenerative dryer.

Do not place the freeze dryer in a location exposed to direct sunlight, rain, wind, or where the relative humidity exceeds 85%. Avoid placing it in environments with dust, corrosive gases, or flammable gases. Do not place it in a location subject to vibration or where condensation may freeze, posing a risk. Ensure adequate ventilation by avoiding placement too close to walls. If use in a corrosive gas environment is necessary, select a freeze dryer with copper tubing or a stainless steel heat exchanger. Operate the freeze dryer in an environment with a temperature below 40℃.

When starting the freeze dryer, slowly introduce gas to pressurize. Observe the refrigerant pressure (small cubic only has a low-pressure refrigerant gauge, while those above 15 cubic meters have both high and low-pressure gauges). Reduce the pressure to 0.2mpa (2.0kgf) and temporarily stop. Then carefully listen for any leaks inside the machine. If there is a leak, use a sound funnel to release the gas.

The waste heat regenerative dryer uses the high-temperature heat energy of the two-stage exhaust gas of the air compressor or uncooled high-temperature compressed air to perform deep desorption regeneration of the adsorbent. It does not require additional heat sources, and there is no reheating during heating. The operation is reliable, and the dew point is stable. Below, let's understand the working principle and applicable scope of the waste heat regenerative dryer.

Waste heat regenerative dryer is a low-speed stirring dryer. The equipment is fitted with stirring paddles that ensure the wet material is fully in contact with the heat carrier and hot surface, thus achieving the drying purpose. This type of dryer is divided into hot air type and conduction type, and the structure is generally horizontal, double-shaft or four-shaft.

During the research on powder in a waste heat regenerative dryer, it was found that the large amount of dust produced in the waste heat regenerative dryer can easily cause electrostatic sparks, whether the powder is in a fluidized bed state or undergoing collection. If there are many electrostatic sparks, it can easily cause an explosion.
