Abstract
The utility model discloses a pressure-sharing annular distributor which is arranged at the inner wall of a distillation separation tower or a related container, and comprises one or more feeding holes, wherein cavities which are gradually reduced are arranged at two sides of the feeding holes; the further the distance to the feeding holes is, the smaller the cavities are; and the feeding holes are mutually communicated at the final stage of cavity. The pressure-sharing annular distributor has the advantages that a vapor phase or a gas-liquid mixing phase enters the device through the feeding holes, and enters a distillation tower or the related container by an air hole or a liquid hole arranged inside each stage of cavity. Because the gas volume is reduced, the volume of the rear stage of cavity needs be reduced to maintain the same pressure inside an annular channel. Thus, the pressures at all positions are the same by the gradually reduced cavities; the vapor phase jetted on the cross section is even; and the uniformity of vapor phase distribution is improved.
Description
Technical field
The utility model relates to a kind of grading ring shape distributor, belongs to chemical industry, petrochemical field rectifying knockout tower internals technology.
Background technology
Tower is the widely used Heat and mass transfer equipment of a kind of energy and chemical engineering industry.Along with the development of rectifying column (destilling tower) technology and the extensive application in industry thereof, the uniformity coefficient that the tower inlet gas distributes is the important indicator of weighing the tower performance, therefore tower gas-phase feed equipment is subject to people's attention more, and is especially particularly important for the board-like tower of major diameter and packed tower.
The gas distributor that extensively adopts in the at present industry mostly is the even distribution that realizes gas in the tower by the straight tube of perforate or other different air flow guiding device.Gas goes out from the orifice flow of distributor pipe diverse location, and its speed is different, so this distributor is difficult to reach the purpose of even distributing gas.And that other gas distributor also exists the gas crushing is large, and there are the shortcomings such as skewness in the distributor top.
Through existing literature search is found, Chinese patent application number is: 01246056.7, name is called: a kind of gas distributor, this technology comprises: pedestal cylindraceous, piston, bottom and spring, pedestal middle part are provided with the piston rod cover, the piston rod string cross behind the piston rod cover and setscrew nut affixed, the bottom middle part is provided with the gas access, spring fitting puts at piston rod, between pedestal gusset and setscrew nut, has pore on the pedestal gusset.After the charge air flow of this distributor need to be backed down piston, go out ejection from the slit, can't guarantee the uniformity that flows in the tower, increased the crushing of charge air flow, and charge flow rate needs precisely control air inlet pipe and tower internal pressure, require very high to control.Simultaneously, this technical battery's fitting is many to be damaged easily, and the life-span is subjected to component limitations large, and airintake direction is axial admission, is easy to occur pouring in down a chimney of liquid when spring failure or when blocking.Therefore this technology has complex structure, the life-span is short, the air inlet crushing is large, in the tower intake uniformity poor, occur that liquid phase is poured in down a chimney, control requires the shortcomings such as high to pressure easily.
Find through retrieval again, Chinese patent application number is: 20050007565.1, name is called: the gas distributor of reactor, this technology comprises the supply pipe array, be used for by only with the compartment system of distributor top reactant being fed to the distributor of reactor bottom, the outlet of distributor is usually towards the bottom or bottom being parallel to, in order to gas or other reactant are sprayed inswept bottom.Because this technology has been arranged a lot of pipelines in tower, the uniformity that flows in the badly damaged tower, and the little resistance that increases air inlet of its caliber.This system architecture is complicated simultaneously, and parts are many, and are fragile, and also are not easy to care and maintenance.Therefore this technology has lack of homogeneity mobile in tube structure complexity, the tower, the charge air flow crushing is large, maintaining is complicated and the high in cost of production shortcoming.
The utility model content
The purpose of this utility model is, a kind of grading ring shape distributor is proposed, the cavity that reduces gradually is being set away from the charging aperture both sides, making the vapour phase that enters in rectifying knockout tower or the associated vessel or gas-liquid mixed rely on mutually pore or the liquid hole offered in the cavitys at different levels enters in rectifying column or the associated vessel, owing to make pressure everywhere identical in the cavity, the vapor-phase material that is ejected into so on the cross section will be very even, improved the uniformity that vapour phase distributes as far as possible.
The technical solution of the utility model: a kind of grading ring shape distributor, be arranged on the rectifying knockout tower inwall, it is characterized in that comprising one or more charging apertures, the multistage cavity that reduces step by step volume is set in the charging aperture both sides, less apart from the charging aperture cavity volume far away of healing, in the end the one-level cavity interconnects; Progression arranges 2 ~ 40.
The cavity that reduces step by step relies on related fittings to be connected with upper plate, lower roof plate and the side plate of cavity by the annular brace ring that is welded on up and down on the rectifying knockout tower inwall, every grade of side plate is connected with upper and lower bottom plate and top board by bolt and connector, and the cavity that reduces gradually is by dwindling upper plate and the lower roof plate area is realized; Every grade of corresponding one or more side plates of cavity are offered uniform venthole on the side plate, pore size is Φ 1 ~ 50mm.
Operation principle of the present utility model is as follows: vapour phase or gas-liquid mixed are mutually by the charging aperture access to plant, rely on pore or the liquid hole offered in the cavitys at different levels and enter the cavity that the both sides setting reduces gradually in rectifying column or the associated vessel, because gas volume reduces, to in the circular passage, keep identical pressure so, the rear class cavity volume is reduced, make pressure everywhere identical by the cavity that reduces step by step like this, the vapor-phase material that is ejected into so on the cross section will be very even, improved the uniformity that vapour phase distributes as far as possible.
The utility model beneficial effect is: just eliminated the dead band that the inner vapour phase of rectifying knockout tower flows owing to having improved vapour phase or gas-liquid two-phase in the uniformity of charging aperture punishment cloth, improved the mass-and heat-transfer effect of tower internals, product purity and yield have been improved, for enterprise wins great economic benefit.

The specific embodiment
The below specifies embodiment of the present utility model: the cavity that reduces step by step relies on related fittings to be connected with top board with the upper and lower bottom plate of cavity by the annular brace ring that is welded on up and down on the tower wall, every grade of side plate is connected with upper and lower bottom plate and top board by bolt and connector, so and the tower wall form the cavity that seals, the cavity that reduces gradually is by dwindling upper and lower bottom plate and the top board area is realized.Every grade of corresponding one or more side plates of cavity.
