A compound cycle water bath vaporizer

Abstract

The utility model relates to a kind of water bath type vaporizer of composite circulation, including open shell, vaporizer, circulating water pump and heating device, the heating device includes one or more combinations of electric heater, combustor and steam nozzle, the inlet of circulating water pump is connected with open shell bottom, the outlet of circulating water pump is connected with the circulating water inlet of vaporizer, and water is circulated in open shell and vaporizer barrel body.The utility model structure is compact, realizes the diversified heating mode, solves the single problem of existing vaporizer heating mode;Circulating water pump forces water to be circulated in open shell and vaporizer shell side, forms efficient water bath circulation system, so that the whole water bath temperature distribution is more uniform, improves the reliability of equipment, circulating water and vaporizer tube bundle are forced to convective heat transfer, while, with water bath natural convection heat exchange in open shell, improve shell side convective heat transfer coefficient, reduce the ice layer thickness outside heat exchange tube, improve overall heat exchange efficiency.
