Changzhou Peng Duo leaks small spray drying equipment energy-saving measures
Small spray drying equipment is needed in many companies, and the drying effect often affects the quality of the product. In the energy consumption of the entire production process, the energy consumption required for the drying equipment is high. Changzhou Yidu Drying Equipment Co., Ltd., after reviewing relevant information, found that the resources required for drying equipment are about 20% of the total energy consumption in the country. The huge energy consumption has undoubtedly increased production costs. The large energy consumption of spray drying equipment has become an urgent problem for drying equipment manufacturers. Here are a few common ways to save energy and reduce consumption on small spray drying equipment .
1, reduce the hot air out of the tower temperature
When the temperature of the hot air entering the tower is constant, the lower the temperature of the hot air outlet tower, the larger the temperature difference between the inlet and outlet towers, and the greater the heat energy that the hot air transfers to the mud for drying, so the hot air utilization rate is higher. However, the exhaust air temperature should not be too low. When the temperature is lower than 75 °C, the powder is too wet, which affects normal drying.
2. Increase the temperature of the hot air into the tower
Under the condition that the temperature of the tower is constant, the higher the inlet temperature of the hot air (also known as the inlet air temperature), the higher the total heat brought in, and the more heat per unit mass of hot air transferred to the mud droplets, the unit hot air The more moisture that is evaporated. In the case of constant production capacity, the required hot air volume is reduced (ie, the heat taken away from the tower when the hot air is removed), the heat consumption of the centrifugal spray dryer is reduced, and the utilization rate and thermal efficiency of the hot air are improved. However, the temperature of the hot air entering the tower should not be too high (not exceeding 600 °C). If the temperature is too high, the top wind splitter will be burned out.
3. Recycling of hot air (exhaust gas)
After the ceramic slurry is spray-dried and powdered, if the hot air of the tower is directly discharged into the atmosphere, this part of the heat loss will be considerable (about 10% to 20% of the energy consumption of the milling process). Therefore, this part of the residual heat should be fully utilized, and the Shangyu Talent Network can recycle the hot air from the tower to the preheating and drying process. In addition to direct recycling, the tower hot air can also be stored or exchanged for reuse by using a heat exchanger.
4. Reduce the evaporation load. The evaporation load of the spray dryer is too large, indicating that the solid content in the material is low. This will greatly reduce the thermal efficiency of the dryer. Appropriately increase the solids content of the feed liquid to reduce the evaporation load of the spray dryer.
5. Preheat the feed solution. Test data indicates that preheating the feed prior to drying is beneficial to shorten the drying cycle.
6. Waste heat recovery and reuse. Exhaust gas often has a higher temperature, and the spray dryer can use a waste heat recovery system to effectively utilize the heat energy of the exhaust gas, which can be used as hot water in the washing process or re-enter the heat exchanger to dry the material again.
A manual massage Foot Spa Massager is a device designed to provide a relaxing and therapeutic foot massage. It is a manually operated handheld device, which means it does not require electricity or batteries to operate. The massager is made up of several parts, including the handle, rollers, and knobs.
To use the manual massage foot spa massager, you simply place your foot on a flat surface and apply the massager to the soles of your feet. The rollers and nodules stimulate the nerves and muscles in the foot, providing a deep tissue massage that helps relieve tension and pain.
The massager is small and lightweight, so you can easily take it with you wherever you go. It's also easy to clean, just wipe with a damp cloth after each use.
Overall, the Manual Massage Foot Spa Massager is a great option for those who are looking for an easy and effective way to relax and soothe their feet. It's affordable, easy to use, and can provide a range of health benefits, including improving circulation, reducing stress, and relieving foot pain and discomfort.
