Abstract:
1. A chimney tray, comprising a tray having a plurality of through-holes, and a plurality of chimneys perpendicularly inserted into the through-holes of the tray and having one or more outlets, wherein each of the plurality of chimneys includes a conical lower end which is integrally formed such that it extends from a lower surface of the tray to make an angle of 10˜40° with respect to a direction of a normal line of the tray, wherein the outlets are formed to penetrate through the chimneys and to face each other so as to be inclined in a tangential direction of a transverse cross section of the chimneys, wherein outlets at one side of the chimneys and outlets at the other side thereof, which are formed to face each other, are inclined at the same angle, wherein the chimneys are arranged such that outlets of respective chimneys, which penetrate therethrough and face each other, are disposed perpendicular to outlets of other chimneys adjacent thereto, which penetrate therethrough and face each other, wherein, in order to more uniformly disperse a liquid reactant on a catalyst bed, the plurality of chimneys is arranged in lattice form, and an imaginary line connecting the outlets of respective chimneys, which penetrate therethrough and face each other, is orthogonal to an imaginary line connecting the outlets of the other chimneys adjacent thereto, which penetrate therethrough.
