Description

Novel high-pressure heater hydroecium baffle device Technical Field The utility model relates to the technical field of water chamber partition plates, in particular to a novel water chamber partition plate device of a high-pressure heater. Background The high-pressure heater hydroecium baffle mainly plays the effect of guiding and distributing the rivers, and it can let the water flow according to specific route, makes water evenly flow through the heating tube bank, fully carries out the heat exchange to can the rational distribution flow, avoid appearing the circumstances of rivers short circuit, with this heating efficiency that improves. In the existing high-pressure heater water chamber, the partition plates are in a stacked design, and in the operation process, the connection parts of the partition plates deform due to the continuous action of high temperature and high pressure. The deformation can damage the sealing surface of the overlapped part, so that leakage of the sealing surface is caused, and once the leakage occurs, a new short circuit channel is formed, so that water directly flows through the channels, bypasses the heating tube bundle and finally reduces the heating efficiency.
