Description
Technical Field
The utility model relates to a flash distillation tower tray to and have flash distillation tower of this flash distillation tower tray.
Background
The flash tower has the function of evaporating gasified gas hydrocarbon, light components and a small amount of moisture in the crude oil in time during the heat exchange and temperature rise process so as to prevent the gasified gas hydrocarbon, the light components and the small amount of moisture from entering the normal pressure heating furnace, thereby reducing the heat load of the normal pressure furnace and the normal pressure tower, reducing the operation pressure of a crude oil system and further saving the energy consumption and the operation cost of the device.
The structure of the flash tower is in consideration of the rectifying tower, a plurality of parallel plate type trays which are arranged in a staggered manner are generally and uniformly arranged in the flash tower, and liquid flows out from a liquid receiving tray, transversely flows through the whole tray, enters a downcomer, enters a lower-layer tray, and flows down layer by layer.
However, the tower tray is mainly designed for a rectifying tower, the flow direction of liquid is continuously bent back and forth, meanwhile, reaction gas is also bent and ascended along with the space, 2 media are continuously blended and reacted in the convection process, a relatively large contact area is obtained, and a large amount of gas is blended into the liquid.
The working principle of the flash tower is obviously different from that of the rectifying tower, particularly, gas is separated from single-phase liquid, and the flash tower is only used for realizing gas-liquid separation and does not generate gas-liquid two-phase reaction, so that gas-liquid contact conditions are not required to be provided.
On the contrary, if the evaporated gas is in cross contact with the raw material liquid again, part of the gas is re-melted into the liquid, so that the efficiency is reduced, and the energy consumption is increased.
In order to solve the above problems, people are always seeking an ideal technical solution.
Disclosure of Invention
The utility model aims at the not enough of prior art to a flash distillation tower tray and flash column that gaseous ascending passageway is more smooth, avoid gaseous too much and liquid contact to take place to fuse is provided.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a flash distillation tray, includes circular or oval tray, and the other side that the liquid falling side of tray and relative with the liquid falling side respectively establish a breach, the bottom surface of tray is the inclined plane, the lower one end of inclined plane corresponds the liquid falling side, is located the breach department of liquid falling side and sets up overflow baffle, and another breach department sets up the baffle.
Basically, the width of the notch on the liquid descending side is larger than that of the notch on the other side.
Basically, the upper end face of the overflow baffle is wavy.
The utility model provides a flash column, includes the tower body and flash column tray, the tray fall by mistake arrange in the tower body, the chamber that corresponds lower floor's tray is held to the falling liquid side of upper tray, two breachs and the tower body lateral wall of each layer of tray form two air current ascending passageways.
Basically, the other two sides of the tower tray are fixed with the inner side wall of the tower body.
Compared with the prior art, the utility model has substantive characteristics and progress, in particular to the utility model, the tower tray is improved on the basis of the structure of the rectifying tower, the liquid dropping side and the opposite side of the tower tray are both provided with notches, the purpose is that two notches can form a channel for air flow rising with the inner side wall of the tower body, and in the process of gas rising below, the gas is not limited by the route of liquid back and forth bending, but flows upwards from the adjacent air flow channel, thereby avoiding the reaction and fusion of excessive gas and liquid contact; in addition, the bottom surface of the tray is designed to be an inclined surface, when each layer of tray is evaporated, the airflow rises to the position of the notch along with the inclined surface, the airflow flowing is prevented from being blocked by the top surface of the plane, and the tray has the advantages of being smoother in air rising channel and avoiding the excessive air from being in contact with liquid to be fused.

Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
As shown in fig. 1-4, a flash tower comprises a tower body 1 and flash tower trays arranged in the tower body in a staggered manner, wherein each flash tower tray comprises a circular or oval tower tray 2, a liquid descending side 3 and the other side 4 opposite to the liquid descending side of each tower tray 2 are respectively provided with a notch, the width of the notch on the liquid descending side 3 is larger than that of the notch on the other side 4, two notches and the side wall of the tower body form a channel, and the other two sides of each tower tray 2 are fixed with the inner side wall of the tower body; the bottom surface of the tray is an inclined plane, the lower end of the inclined plane corresponds to the liquid descending side 3, an overflow baffle 5 is arranged at a notch positioned on the liquid descending side, the upper end surface of the overflow baffle is wavy, a baffle 6 is arranged at another notch, the liquid descending side of the upper tray corresponds to the containing cavity of the lower tray, and two notches of each tray and the side wall of the tower body form two air flow ascending channels 7.
The working principle is as follows:
liquid flows in from the uppermost end, enters the tower tray at the top end, flows into the cavity of the lower tower tray from the overflow baffle 5, is accumulated by the lower tower tray, then enters the cavity of the lower tower tray from the overflow baffle, and so on; in the process, the airflow evaporated at the bottom end flows upwards, because of the existence of the two gaps, two ascending channels 7 and 8 are formed with the inner wall of the tower body, the airflow selects the ascending channel to flow upwards along a straight line nearby, meanwhile, evaporation always exists in the liquid flowing process, and the gas generated by evaporation meets the bottom surface of an upper tray in the upwards flowing process, and because the bottom surface is an inclined surface, the airflow can easily move into the ascending channel along the inclined surface and then flows upwards along with the ascending channel.
The structure provides enough space and a shorter path for the rising of the gas flow, avoids excessive contact with liquid, and ensures that the gas is discharged more fully.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
