Description

Sand-proof structure of evaporative air cooler

Technical Field

The utility model relates to a heat exchange equipment technical field, in particular to evaporation formula air cooler prevent wind husky structure.

Background

The evaporative air cooler is common heat exchange equipment in the field of petroleum and chemical production, and the equipment enhances the cooling effect on hot fluid in a heat transfer tube bundle by utilizing the evaporation latent heat of a water film outside the heat transfer tube bundle. However, in practical application, the outer wall of the heat exchange tube of the air cooler is often scaled, so that the heat exchange effect of the equipment is obviously reduced, the requirement of heat transfer parameters of a production process cannot be met, the production capacity of a total device is forced to be reduced, and the yield and energy consumption of enterprises are increased.

The reason for scaling the outer wall of the heat exchange tube of the evaporative air cooler is mainly environmental factors. Since the cabinet of the air cooler is not closed, it is generally installed outdoors. When the dust, the raised ash and other suspended matter impurities in the working environment are more, the dust, the raised ash and other suspended matter impurities are sucked into the air cooler by the fan and are deposited and gathered on the surface of the outer wall of the light pipe or among the spaces of the fins. After being wetted by spray water or rainwater, the impurities can be agglomerated into slime to form scaling points at the accumulation positions. In areas with much rainfall, salt ions and acidic substances dissolved in rainwater can be concentrated and attached on the surface of the pipe wall, and cause corrosion to the heat exchange pipe material. The air inlet of the existing evaporative air cooler is only slightly separated by a hollow net, suspended impurities such as dust and ash are not obviously blocked, and the hollow net is fixed with the air inlet, so that the air cooler is inconvenient to disassemble and clean.
