Abstract
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.
