The waste heat recovery dryer mainly consists of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. It is widely used in the fields of biology, medicine, and food. During daily use, it is necessary to strictly abide by the operating procedures to ensure the service life of the waste heat recovery dryer.

Before starting the vacuum pump of the waste heat recovery dryer, be sure to check if the water outlet valve is tightened, if the inflation valve is closed, and if the contact surface between the plexiglass cover and the rubber ring is clean and free of debris, and the seal is good. Then, during operation, it should not be turned on and off frequently. If the refrigerator stops running due to misoperation, it cannot be started immediately; at least 20 minutes later, it can be restarted to avoid damaging the refrigerator. In addition, you also need to know that when the waste heat recovery drying process is finished, the cold trap must be inflated slowly to avoid crushing the vacuum gauge. The sample container should be placed on a metal plate, containers should not be stacked on top of each other, and there should be no gaps between the containers and the metal plate. In particular, now that some sample materials have been dried, please turn off the main power supply, fully open the vent valve, and drain the water from the vacuum pump at the same time. Open the vacuum pump's drain valve, first vent to drain the water from the vacuum pump, then add vacuum pump oil from the filling port to the position between the two red lines. Of course, the oil level of the waste heat recovery dryer instrument must also be checked frequently. If you have any questions, you can call us at any time for consultation.

When the waste heat recovery dryer is running, its inlet and outlet cannot be reversed. It should be installed horizontally. An air filter and oil mist separator should be installed at the air inlet; otherwise, the oil mist and dust in the compressed air will clog the capillaries of the adsorbent, reducing the adsorption capacity and shortening the service life. In fact, if the adsorbent needs to be replaced without stopping the air during use, a bypass system should be designed. So what everyone needs to do is to pressurize first and then turn on the power. If the power is turned on before pressurization, due to poor check valve operation (especially at lower pressures), an abnormally large regeneration flow may occur at the start. In addition, it is necessary to prevent compressed air from being used in the powder gas due to poor operation of the electromagnetic reversing valve. Therefore, you need to know that if it is not used for a long time, the adsorbent may become wet. Before reuse, it is necessary to close the valve on the secondary side of the waste heat recovery dryer for regeneration and dry the adsorbent. The air volume used by the pneumatic system should be within the rated output flow rate of the waste heat recovery dryer; otherwise, the air dew point temperature will not meet the requirements. When the specified time limit is used, all adsorbents in the cylinder should be replaced. In addition, during use, a precision filter should be installed at the output end to prevent the powder generated by the adsorbent in the cylinder from mixing into the compressed air under the continuous impact of the compressed air.

The above article content is an introduction to the usage of the waste heat recovery dryer. Friends who didn't understand it before can read it. Okay, that's all for today's knowledge points. I hope it can help relevant personnel.
