What are some easily overlooked factors concerning desiccant regenerative adsorption dryers?
Zero-purge regenerative adsorption dryer It is a new type of equipment that combines a refrigeration system, a vacuum system, a heat transfer oil heating system, and a dehumidification system. Of course, many related issues are involved during use. We will give a brief introduction to these here.
A frequently overlooked issue when operating a zero-purge regenerative adsorption dryer is its inlet air temperature. In fact, the compressed air entering the dryer is saturated air with a certain temperature. Under the same pressure conditions, of course, for every increase in its temperature 5 ℃, the saturated water content increases 30% approximately, meaning the humidity load entering the adsorption dryer increases 30% approximately; many users have overlooked this issue before Zero-purge regenerative adsorption dryer during operation. Now that we've explained this, you should understand. In addition, the adsorption capacity of the adsorbent decreases as the temperature rises, so as the compressed air inlet temperature rises, the drying efficiency of the adsorption dryer decreases. Of course, at this time, for every increase in its inlet air temperature 5 ℃, the outlet dew point of the finished gas will increase 8~10 ℃. Therefore, when using it, we must lower the inlet air temperature as much as possible for the benefit of the adsorption dryer. If you weren't clear about this before, you can learn more now.
Of course, another common problem when using a zero-purge regenerative adsorption dryer is oil mist. It generally refers to oil-lubricated reciprocating air compressors ( except for labyrinth type, packed with positive pressure protection, and low-power completely oil-free machines ) there is still a certain amount of lubricating oil in the exhaust gas, so at this time it mainly depends on its structure and specifications, which is approximately 6~15mg/m3 . Of course, when using an oil-injected screw air compressor with an oil content comparable to that of an oil-free piston machine, its oil content depends on the efficiency of the oil-gas separator and the high and low exhaust temperature. Another point to note is that the regeneration gas flow rate cannot be adjusted arbitrarily during the operation of the zero-purge regenerative adsorption dryer. In addition, for a hot air dryer, the instantaneous flow rate of the regeneration gas cannot be too small; otherwise, it will reduce the heat transfer efficiency of the regeneration gas as a heat carrier, causing local overheating and a large part of it to be unheated.
