The invention particularly discloses a pulsation device of a heat exchanger for strengthened descaling, and belongs to the technical field of energy source. The pulse device of the heat exchanger can solve the problem of pipeline scaling and low heat exchanging efficiency during the process of heat exchange between non-clean water and clean water. The pulse device of the heat exchanger is provided with two water inlets and two water outlets; the two water inlets are flow in from the tangential direction so as to rotate a moving disk; when the water outlet of the moving disk is rotated to a water storage space at one face of a fixing disk, water cannot flow through the other one water storage space; two water storage spaces of the fixing disk are in hard sealing connection; the continuous rotation of the moving disk realizes the water division, and further the pulsation of water flow is realized; two water outlets are respectively connected with the water inlets of the heat exchanger, so that the heat exchanger is smoothly and efficiently worked. The pulsation device of the heat exchanger for strengthened descaling is applied to scaling prevention and descaling of the heat exchanger pipeline.
Description
technical field [0001] The invention relates to a pulsation device for strengthening descaling of heat exchangers, belonging to the technical field of energy. Background technique [0002] Sewage source or surface water source is a kind of water source. Compared with groundwater, its main feature is that it has a large content of impurities, which is easy to form dirt on the heat exchange wall and pipes, which not only accelerates the corrosion of pipe walls, but also greatly reduces the service life of heat exchange equipment. It will affect the heat transfer efficiency and increase the flow resistance of the fluid. Therefore, anti-scaling and descaling are important technologies for using non-clean water for heat exchange. [0003] Unclean water such as sewage and surface water is rich in low-grade heat energy, which can be extracted by using heat exchangers to provide heating and air conditioning for buildings. According to the calculation of my country's existing sewag...
