    • An evaporation apparatus adapted to evaporate a portion of a liquid material containing two or more types of components for use in exothermic vapor-phase catalytic reaction and feeding the same to a reactor for the vapor-phase catalytic reaction. The evaporation apparatus comprises a can body provided at its apical part with a vapor exhaust port; an evaporation section for heating the liquid material inside and/or outside the can body to thereby evaporate the same; a column section consisting of a column containing trays and/or packing material, connected at its column bottom to the vapor exhaust port; a liquid supply tube for supply of the liquid material, provided at the middle or higher position of the column section; a vapor exhaust tube for exhausting the vapor from the apical part of the column section and feeding the same to the reactor for vapor-phase catalytic reaction; and a liquid discharge tube for discharging the liquid material lying in the can body.
    • 一种蒸发装置,用于蒸发含有两种或更多种类型的组分的液体材料的一部分用于放热气相催化反应,并将其送入用于气相催化反应的反应器。 蒸发装置包括在其顶部设置有蒸气排出口的罐体; 用于将罐体内部和/或外部的液体材料加热以使其蒸发的蒸发部分; 由塔底和/或包装材料的塔组成的柱部分,其柱底部连接到蒸气排出口; 用于供应液体材料的液体供应管,设置在柱部分的中间或更高位置; 蒸汽排气管,用于从柱段的顶部排出蒸气,并将其送入反应器进行气相催化反应; 以及用于排出位于罐体中的液体材料的液体排出管。
