The circulating water available for air compressor should be specifically analyzed from three aspects: water quality, water temperature and water volume. Cooling water will not be polluted by the fully enclosed pipeline refrigeration equipment and can be recycled. The outlet water temperature is generally controlled at 38℃ + 2℃. As long as the outlet water is properly cooled, the recycling can also meet the water temperature required for equipment cooling. Due to factors such as employees taking a bath and water vapor evaporation, the total amount of cooling water is reduced, and recycling cannot ensure sufficient and stable water volume. If the original air compressor water supply pump is retained, when the water volume of the circulation system is insufficient, it can be solved by replenishing water once.
When the water temperature of the reservoir reaches 27℃, the average outlet water temperature of the air compressor reaches above 45℃, which far exceeds the cooling temperature requirement of the equipment. The reservoir is not capped, causing a large amount of clinker dust to enter the reservoir. Because clinker dust is water-hard, and the cooling pipe diameter in the intercooler and oil cooler is small, the intercooler and oil cooler of many air compressors are blocked after one month of operation. Because the reservoir is high, the operator who replenishes water once cannot control the amount of water replenishment. Each time the water is replenished, the pump is not stopped until the reservoir overflows, resulting in water waste and environmental pollution. Main rectification measures. The water pump pipeline is raised 3m above the top of the reservoir, and this space is used to build a cooling tower to force cooling of the circulating water and reduce the water temperature. A fully enclosed hut is built with cotton tiles, and the cooling tower and cooling pool are completely enclosed to prevent clinker dust from entering. At the same time, the return water pipe at the bottom of the reservoir is connected to the manhole door on the side of the reservoir, and the original bottom is connected to a pipe to the chute at the bottom of the reservoir. Water is released regularly, so that the sediment in the reservoir can be discharged regularly to keep the water clean.
