Embodiment 1

[0024] One end of the inner pipe 4 in Embodiment 1 can be seamlessly welded or screwed to the inner side of the center hole of the first flange 2 .

[0025] The closed connection between one end of the outer tube 3 and the first flange 2 in Embodiment 1 is that the end of the outer tube is sleeved on the central hole boss of the first flange 2, and the end of the outer tube is connected to the first flange along the first flange. The end face of the blue plate is seamlessly welded.

[0026] In Embodiment 1, one end of the inner tube fixed to the first flange 2 is provided with a sealing plate 6 at the other end, and the center of the sealing plate is provided with a support column 7 that enables the inner tube to be supported on the non-porous flange, and the non-porous flange 9 A blind hole corresponding to the support column is provided.

[0027] In Embodiment 1, the other end of the outer tube 3 is fixed to the second flange 8, that is, the end of the outer tube 3 is engag...

Embodiment 2

[0033] The liquid outlet pipe 12 of embodiment 2 can also be symmetrically arranged in multiple rows, and it is suitable for a packed tower with a larger liquid output, and the liquid output of the inner pipe 4 corresponding thereto should be greater than the liquid output of the outer pipe 3 of embodiment 2, That is, the diameter of the liquid outlet hole 4-1 of the inner tube 4 can be increased or the number of the liquid outlet hole 4-1 can be increased.

Abstract

The invention relates to a composite feed pipe of a packed tower. The composite feed pipe comprises an inner pipe and an outer pipe, as well as a first flange, a second flange and a holeless flange, which can form a jacket space between the inner pipe and the outer pipe, so that liquid with kinetic energy, which enters into the inner pipe can enter into the jacket space via a liquid outlet hole of the inner pipe, then the kinetic energy of the liquid can be completely transformed to potential energy, and the impacts of flow rate of inlet liquid on the liquid outlet quantity of each of liquid outlet pipes of the outer pipe can be eliminated. When the liquid flows out of the liquid outlet pipes arranged at the bottom of a pipe body of the outer pipe, the quantity of the liquid is only dependent on the aperture and the potential energy, the liquid outlet quantity of each liquid outlet pipe is equivalent as long as all the liquid outlet pipes of the outer pipe are mounted horizontally and can change along with the changes in the inlet quantity of the inner pipe. The composite feed pipe disclosed by the invention can effectively solve the difficult problem that the liquid distribution of the traditional feed pipe is non-uniform, and compared with an existing feed device, and the composite feed pipe has the prominent advantages that the discharge distribution is uniform and can not be affected by the flow rate of the inlet liquid.

Description

technical field [0001] The invention belongs to a packed tower, and relates to a composite feeding pipe of a packed tower. Background technique [0002] A packed tower, the upper part of which is provided with a feed pipe in the form of a single pipe or H pipe in a horizontal state corresponding to the upper and lower sides of the primary distribution tank, and the feed end of the feed pipe is fixedly connected with the feed hole of the tower wall through a flange , the closed end of the feed pipe is connected to the corresponding tower wall support seat. There are liquid distribution holes distributed at the bottom of the feed pipe, and the diameter and quantity of the distribution holes are set according to the liquid flow requirements. [0003] The problem of uneven liquid distribution in the above-mentioned feed pipe affects the gas-liquid exchange efficiency. The reason is that the flow velocity of the pressure-carrying liquid changes after entering the feed pipe. The...
