Abstract
The utility model discloses a coking fractionating tower. In the structure of the coking fractionating tower, an outlet of a downcomer on a heating tower plate on a first layer is arranged under liquid level of oil liquid of the tower bottom, and the interior of the downcomer on the heating tower plate on the first layer is provided with a bubble removing device; the interiors of the downcomers on the tower plates on a second layer and a third layer are provided with dirt collection device. The normal state of the gas-liquid phase water flow on the tower plates can be ensured through the coking fractionating tower, and the tower plates can be ensured to play normal mass-transfer and heat-transfer effects.
Description
The utility model relates to a kind of fractionating column, especially coking fractional distillation column.
Coking fractional distillation column is widely used in industrial production as a kind of chemical industry equipment, especially in oil refining industry.The heating column plate of existing coking fractional distillation column is divided into three layers, decompression residuum is flow to by downspout on the second layer heating column plate through the 3rd layer of heating column plate, flow on the ground floor heating column plate through downspout again, after the downspout on the ground floor heating column plate and the seal pot of downspout bottom flow at the bottom of the tower, decompression residuum contacts with overheated Device in Gas in this process, conducts heat and mass transfer.Guaranteeing that the fractionating column column plate is normally brought into play conducts heat and effect of mass transmitting, must guarantee then that gas-liquid phase waterpower flows on the column plate to be in normal condition.Owing to carry catalyst granules in the coking charging, carry coke powder in the Device in Gas, the flow velocity of fluid in downspout is lower, there is flow blind angle in the downspout simultaneously, seal pot and downspout incrustation clogging often take place in operation, thereby cause heating waterpower flow abnormalities on the column plate, make heating plate can not bring into play due effect.
The purpose of this utility model is to provide a kind of mobile coking fractional distillation column that is in normal condition of gas-liquid phase waterpower on the column plate of guaranteeing to heat.
For reaching above-mentioned purpose, the downcomer outlet port on the utility model ground floor heating column plate is positioned under the liquid level of fluid at the bottom of the tower.
The plane inner tubal wall that falls the liquid visitor of ground floor heating column plate is provided with the bubble trap of cross section for " L " shape, and the bubble trap bottom surface is a screen cloth, and the side is the metallic plate of screen cloth or metallic plate that has liquid flow hole or band filter grid.
The plane inner tubal wall of the downspout of the second layer and the 3rd layer of heating column plate is provided with the dirt pocket of cross section for " L " shape, and the dirt pocket bottom is for having the metallic plate of drain hole, and the side is to have the metallic plate of liquid flow hole or the metallic plate of band filter grid.
Adopt behind the said structure because seal pot is not established in the downspout below on the ground floor heating column plate, but the outlet of downspout is located at nature fluid-tight under the fluid liquid level at the bottom of the tower, having avoided original like this influence the mobile phenomenon of gas-liquid phase waterpower because seal pot incrustation stops up downspout.In the downspout of ground floor heating column plate, bubble trap is set and reduces liquid carrying secretly upper strata column plate gas.Dirt pocket is set on the second layer and the 3rd layer heating column plate can be prevented that downspout from influence because of incrustation stops up and heat column plate and bring into play due effect.The bottom of bubble trap and dirt pocket can be flowed out by the side because of incrustation stops up back liquid, and this coking fractional distillation column can guarantee that gas-liquid phase waterpower flows on the column plate and be in normal condition, thereby guarantees the column plate heat and mass effect of bringing into normal play.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the structural representation of the utility model coking fractional distillation column.
Fig. 2 is the structural representation of the utility model ground floor heating column plate.
Fig. 3 is the structural representation of the utility model second layer heating column plate.
As shown in Figure 1, downspout 2 outlets on the utility model coking fractional distillation column ground floor heating column plate 1 are positioned under the liquid level of fluid at the bottom of the tower, the plane inner tubal wall of the downspout 2 of ground floor heating column plate 1 is provided with the bubble trap 3 of cross section for " L " shape, and the plane inner tubal wall of the downspout of the second layer and the 3rd layer of heating column plate is provided with the dirt pocket 4 of cross section for " L " shape.
By Fig. 2 and Fig. 3 as can be known, the bottom of bubble trap 3 is a screen cloth 5, and the bottom of dirt pocket 4 is the metallic plate 6 that has drain hole, and flow velocity is lower when liquid flow, and coke powder that carries in the liquid and catalyst granules can be blocked by dirt pocket 4, thereby guarantees that downspout is not blocked.Bubble trap 3 can be removed the bubble of liquid entrainment the gas that reduces liquid entrainment, and this coking fractional distillation column can guarantee to heat on the column plate gas-liquid phase waterpower and flow and be in normal condition, the mass-and heat-transfer effect that column plate is brought into normal play.
