Problems solved by technology

For the downcomer with this structure, the resistance in the downcomer is small, and the flow rate of the liquid in the downcomer is high, so that the separation efficiency of the liquid in the downcomer is low. In order to realize the separation of the gas from the liquid more effectively out, the height of the downcomer can be increased, and the arcuate or circular cross-sectional area of ​​the downcomer can be increased, but the height or diameter of the plate tower is increased, which increases the production cost of the equipment

Embodiment 1

[0025] figure 1 , 2 A schematic structural diagram of Embodiment 1 of the present invention is given. exist figure 1 , 2 Among them, the tray with energy dissipator downcomer in this embodiment is composed of a liquid receiving tray 1 , a tray plate 2 , a support plate 3 , a downcomer plate 4 , a baffle plate 5 , and a tower body 6 .

[0026] A downcomer plate 4 is welded on the left side of the inner wall of the tower body 6, and a liquid receiving plate 1 is welded on the right side. The liquid receiving plate 1 is used to bear the liquid flowing down from the upper tray, and the downcomer plate 4 is welded with The support plate 3, the support plate 3 and the liquid receiving plate 1 are connected with a tray plate 2 with a threaded fastening joint, and the tray plate 2 is processed with holes, and the gas flows in from the lower part of the tower body 6, and the gas flows in from the tray plate 2. The holes flow to the tray plate 2 for mass transfer and heat transfer b...

Embodiment 2

[0029] exist image 3 , 4 Among them, the tray with energy dissipator downcomer in this embodiment is composed of liquid receiving tray 1, tray plate 2, support plate 3, downcomer plate 4, baffle plate 5, tower body 6, and metal packing 7. . Two spoilers 5 are welded on the inner wall of the tower body 6 in the downcomer formed between the downcomer plate 4 and the tower body 6 and the downcomer plate 4 , and one spoiler plate 5 is welded on the inner wall of the tower body 6 , a baffle 5 is welded on the downcomer 4, the two baffles 5 are parallel to each other and arranged in a staggered manner, the baffle 5 is processed with flow-limiting holes with a diameter of 5 mm, and one flow-limiting hole is connected to the adjacent The center-to-center distance of a restrictor hole is 7.5mm. Welded on the inner wall of the tower body 6, the gap between the outer end of the baffle plate 5 and the downcomer plate 4 is 30% of the distance between the downcomer plate 4 at the positi...

Embodiment 3

[0031] In this embodiment, two baffles 5 are welded on the inner wall of the tower body 6 in the downcomer, two baffles 5 are welded on the downcomer 4, and the baffles welded on the inner wall of the tower body 6 5 and the baffles 5 welded on the downcomer 4 are alternately arranged. Welded on the inner wall of the tower body 6, the gap between the outer ends of the two baffle plates 5 and the downcomer plate 4 is 20% of the distance between the downcomer plate 4 at the position of the two baffle plates 5 and the inner wall of the tower body 6. The gap between the outer ends of the two baffles 5 on the downcomer 4 and the inner wall of the tower body 6 is 20% of the distance between the downcomer 4 and the inner wall of the tower body 6 at the positions of the two baffles 5 . The distance between one baffle 5 and the upper and lower adjacent baffles 5 is 20% of the height of the downcomer. One baffle 5 is parallel to the adjacent baffle 5 and parallel to the bottom surface o...

Abstract

The invention relates to a tray equipped with energy dissipator downflow spout, one side in the tray is provided with down-flow plate in axial direction, and the other side is equipped with liquid-receiving plate, the down-flow plate and tray forms the downflow spout, down-flow plate is equipped with supporting plate, supporting plate and liquid-receiving tray are provided with tray plate equipped with holes, the down-flow spout is equipped with spoiler or energy dissipator on metallic filler. The tray reduces flowing speed of liquid material in down-flow spout, increases retention time and improves vapor-liquid separation rate. The applied tray reduces height and diameter of plate tower and production cost, and increases mass transfer efficiency and productivity when height and diameter of plate tower is defintive. The invention is characterized by rational design, simple construction, high efficiency, low production cost and wide application in chemical industry, oil industry and petrochemical industry.

Description

technical field [0001] The invention belongs to the technical field of vapor-liquid and liquid-liquid separation, and in particular relates to a tray with a downcomer of an energy dissipator. Background technique [0002] Tower equipment is one of the most important equipment in the production of chemical industry, petroleum industry, petrochemical industry and so on. It can fully contact the gas (steam) liquid or liquid-liquid two phases to achieve the purpose of interphase heat transfer and mass transfer. The unit operations that can be carried out in the tower equipment include: refining, absorption, desorption, humidification and cooling of gas, etc. In chemical, petrochemical and oil refineries, the performance of tower equipment has a major impact on the product output, quality, production capacity and consumption quota of the entire device, as well as the treatment of three wastes and environmental protection. According to the internal structure of the tower, the to...
