专利汇可以提供Multi-stage flash desalinator专利检索,专利查询,专利分析的服务。并且PURPOSE:To accelerate boiling under reduced pressure, while facilitating the formation of a critical condition, by providing piping or a channel for supply of steam or gas at the squeezed flow part of a venturi below the partition wall of the titled multi-stage flash desalinator. CONSTITUTION:Steam supply piping 20 is provided at the bottom plate 19 of an evaporation chamber in the vicinity of the throat part 17 of a venturi 16. Brine B flowing out of an evaporation chamber 15a at a preceding stage, i.e. inflow brine to said venturi 16, is held under a saturated condition by flash evaporation in the evaporation chamber 15a at the preceding stage, so that it is changed into a critical state by the action of steam supplied through the steam supply piping 20 when it passes through the throat part 17 of the venturi 16 having the minimum section area. Hence, said brine is flash evaporated by letting it flow into an evaporation chamber 15b at the following state held below the critical pressure. Consequently, the effects to reduce static pressure in the vicinity of the throat part 17, to accelerate boiling under reduced pressure and to facilitate the formation of the critical condition are exhibited.,下面是Multi-stage flash desalinator专利的具体信息内容。
