What are the main factors affecting the cooling effect?
Generally, there are the following reasons: 1. Insufficient amount of cooling water； 2. Scale and sediment accumulation on the cooler tube walls impair heat transfer ； 3. The presence of various debris in the water can accumulate in the water cooler, blocking the passages and causing poor flow of water, which in turn affects the cooling efficiency ； 4. Due to the side reactions in methanol synthesis, a paraffin-like substance is produced (this becomes more apparent as the catalyst ages), which adheres to the inner walls of the water condenser tubes, thereby affecting heat transfer efficiency and reducing the effectiveness of water cooling.
Circulating water quality, water volume, water pressure, supply water temperature； Circulating gas thermometer gas flow rate ； Waxing effects.
1. The design parameters of the water cooler itself, such as the heat exchange area, the material of the heat exchange tubes, and the medium undergoing heat exchange. 2. Water temperature and flow rate. 3. Whether the water quality is clean and whether there is any scaling. Sometimes, if a heat exchanger used for heat exchange with methanol leaks, a biological membrane forms on the tube walls, which significantly affects the heat exchange efficiency. Additionally, the accumulation of paraffin also significantly affects heat transfer. 4. The room temperature also has a certain impact
