Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of deaerators, in particular to a mechanism for recycling the heat of residual water inside a deaerator. Background Art
[0002] Deaerator is a device used in industrial boiler systems to remove oxygen and other gases dissolved in feed water. During the deaerator process, water is usually heated to a temperature close to or above its saturation temperature to reduce the solubility of oxygen in the water by increasing temperature and pressure, thereby achieving the purpose of deoxygenation. When the deaerator stops running or performs drainage operations, the water inside may not be completely discharged immediately. The residual water will maintain a certain temperature because it was heated before, that is, it carries heat. Some measures can be taken to recycle and utilize this heat to improve the energy efficiency of the system. Since the main function of the deaerator is to remove dissolved oxygen from the boiler feed water to prevent corrosion and oxidation of boiler pipes and other equipment, some oxides, scale, sediments, etc. will accumulate inside the deaerator during use. These impurities will cause pipe blockage when recycled, affecting the normal operation of the device, and there will be a large number of impurities on the surface of the filter plate after long-term use. If it is not cleaned immediately, the filter holes will be blocked, affecting the filtration efficiency.
