Abstract
一种具有填料式降液管的新型塔板，它是对石油炼制及化工工业领域内分离设备中塔的降液管的结构改进。它主要是通过在降液管内部设置适量的特殊填料和对塔板的受液盘进行改进使之成为鼓泡传质区，从而达到降低塔板压降与雾沫夹带分率和有效地提高单塔的处理能力的目的。
The utility model relates to a new type of tray with a packing downcomer, which is an improvement on the structure of the downcomer of the tower in the separation equipment in the field of petroleum refining and chemical industry. It is mainly by setting a proper amount of special packing inside the downcomer and improving the liquid receiving tray of the tray to make it a bubbling mass transfer area, so as to reduce the pressure drop of the tray and the mist entrainment fraction and effectively improve The purpose of single tower processing capacity.
Description
Technical field
The utility model relates to a kind of novel column plate with material filling type downspout, and it is the architecture advances to the downspout of tower in the separation equipment in petroleum refining and the chemical engineering industry field.It mainly is to make it to become the bubbling mass-transfer zone by an amount of particular fillers being set in downspout inside and the seal pot of column plate being improved, thereby reaches the purpose that reduces plate pressure drop and entrainment branch rate and improve the disposal ability of single tower effectively.
Background technology
In oil, petrochemical industry, chemical engineering industry, most separation equipments remain plate column.The research of traditional column plate mainly is that hydrodynamics and the mass-transfer performance round various column plates carries out, and very few to the optimization research of other internals of forming tower integral body, as according to distributing the suitable downspout size of design alternative, downcomer structure, downspout lower edge height etc. along the load of the vapour-liquid on each laminate of tower.Simultaneously, how the column plate area at seal pot place makes full use of etc. and all to have many problems on the existing various column plates.The research of carrying out in this respect provides a direction to the disposal ability that improves existing tower.It is generally acknowledged that it is the governing factor of the downspout liquid load upper limit that the downspout bubble is carried secretly.About test and theoretical analysis result show, in normal operation range, bubble carry secretly plate efficiency is influenced not remarkable.The matter of utmost importance that runs into when improving single tower treating capacity is that the gas phase load is excessive.Some destilling tower in the actual production (as crude oil atmospheric tower, catalytic fractionator etc.) can run into because effectively usable area is little on the column plate when improving treating capacity, causes the valve opening KE factor too big, and plate pressure drop increases, the unequal situation of liquid distribution on the plate.Therefore, be necessary the downcomer structure pattern is optimized design,, reach the purpose that improves single tower disposal ability to make full use of the effective bubbling area of column plate.
Summary of the invention
The purpose of this utility model provides one one kinds of novel column plates with material filling type downspout with regard to being to avoid above-mentioned the deficiencies in the prior art part.It mainly is at the tower situation that is applied at present in the separation process, develop a kind of novel downspout that is applicable to various plate columns, to increase the bubbling area area on the column plate, make the downspout bottom become bubbling area, realize that simultaneously the dynamic equilibrium of gas-liquid load in column plate and downspout distributes, to adapt to the variation of different gas-liquid loads and different liquid-gas ratios in the tower.Therefore, this utility model makes it to become the bubbling mass-transfer zone by an amount of particular fillers being set in downspout inside and the seal pot of column plate being improved, thereby reduces plate pressure drop and entrainment branch rate and improve the disposal ability of single tower effectively.It mainly is to be made of filler, downspout and column plate, and its major technology characteristics are at an amount of filler of downspout inner filling, and the seal pot on column plate is provided with the bubbling element and makes it to become mass-transfer zone, its downspout be set to suspension type.
Description of drawings
Accompanying drawing is structural representation of the present utility model, wherein: 1----column plate 2----downspout 3----tower body 4----filler 5----seal pot 6----bubbling element
The specific embodiment
Below in conjunction with embodiment in detail technical characterstic of the present invention is described in detail.
In actual design with in making, downspout of the present utility model is to adopt underslung structure, and in downspout, load onto filler, purpose is to adopt appropriate filler can make downspout become gas-liquid channel simultaneously, realizes that the dynamic equilibrium of gas-liquid load in column plate and downspout distributes.Simultaneously, traditional seal pot district is installed the bubbling element, make it to become the gas-liquid mass transfer district,, increase disposal ability to make full use of the column plate area.The invention effect
The utility model compared with prior art has following outstanding advantage:
1. owing to adopted underslung downcomer structure, the layout district of float valve on the column plate is strengthened, perforated area and gas actual circulation area in tower increases, thereby has reduced plate pressure drop and entrainment branch rate, can improve the disposal ability of single tower effectively.
2. this kind downcomer structure adopts the mode of dynamic liquid seal, can prevent the phenomenon of stopping up downspout, causing liquid flooding in the tower of gathering owing to solid particles such as dirt, anvil cinder in the tower effectively.This point is unholiness or particularly important when containing solid particle when the handled material of destilling tower.
3. owing in the downspout appropriate filler is housed, make downspout become gas-liquid channel simultaneously, the mass-transfer efficiency of column plate is improved.
Claims (2)
1. novel column plate with material filling type downspout, it mainly is to be made of filler (4), downspout (2) and column plate (1), it is characterized in that the filler (4) that downspout (2) inner filling is an amount of, and the seal pot (5) on column plate (1) district is provided with bubbling element (6) and makes it to become mass-transfer zone.
2. a kind of novel column plate with material filling type downspout according to claim 1 is characterized in that the suspension type that is set to of downspout (2).
