Air cooler

Air compressor intermediate cooler is generally shell-tube structure. Water is supplied inside the pipe, and gas is supplied between the pipes, which plays a cooling role through the heat exchange of fluid inside and outside the pipe. The reasons that affect the cooling effect of compressor intermediate cooler include: 1) insufficient cooling water. The heat of the air is not enough to be taken away by the cooling water, resulting in the increase of the next level of suction temperature, the decrease of gas density, and finally the reduction of exhaust volume. Therefore, the water supply pressure of cooling water should be closely monitored during operation to control the water supply. The process generally requires that the cooling water pressure should be greater than 0.15MPa (surface pressure); 2) the cooling water temperature is too high. High water temperature reduces the temperature difference between water and gas, and reduces the effect of heat and cooling. Even if the amoun...

Under the design working condition, the positive and return air volume of the Heat section of the switching heat exchanger (or cooler) is basically equal. While in the cold section, the return flow volume must be larger than the positive flow air volume, and keep a certain proportion relationship, so that the temperature difference of the cold end is within the required range of moisture and carbon dioxide self-elimination, and the temperature difference of the hot end should be appropriate. In actual operation, when the temperature condition fluctuates, the method of changing the air volume or the distribution of product gas volume is also often used to adjust. When the middle temperature deviation occurs between two groups of switching heat exchanger (or between two groups of refrigerators), air inlet stop valve (or thin film butterfly valve) can be used for adjustment. The group with lower temperature in the middle part is larger, increasing air ventilation. In this way, the requ...
