Description

Structured packing component and the fluid-fluid contact arrangement using the structured packing component
Technical field
It is set the utility model is related to a kind of structured packing component and using the fluid-fluid contact of the structured packing component Standby more particularly to a kind of fluid that is used for contains solid particle, easy fouling, coking, the rule for holding susceptible to plugging harsh application field Whole filler assembly and the fluid-fluid contact arrangement using the structured packing component.
Background technology
Structured packing is one of industrial main mass transfer technology, for fluid-fluid contact arrangement.Typical fluid- Fluid contacting equipment refers to the equipment for a kind of fluid (such as liquid) to be made to be contacted with one other fluid (such as gas), two Kind fluid reverse flow usually relative to each other, for example, distillation, absorption, washing, air lift, heat exchange etc., connect in gas (or vapour)/liquid In the case of touching, gas forms continuous phase.
Fluid-fluid contact arrangement generally includes structured packing component when use structured packing, and structured packing component is then Generally include multiple unit of structured packing.Unit of structured packing is made of the sheet material for being pressed into ripple, and each sheet material is parallel to be combined one It rises.Generally there is decorative pattern on the surface of corrugated plate and/or containing perforation.These corrugated plates are combined into a filler unit, each corrugated plate In ripple tilt an angle compared with vertical direction, adjacent two corrugated plates ripple direction is opposite.In fluid-fluid contact arrangement When inside being loaded, two neighboring filler unit rotates an angle and stacks, and usual angle is 90 °.Industrially, it is typically regular to fill out Material unit height is generally 8-12 inches (203-305mm).
The advantages of structured packing is large specific surface area, mass-transfer efficiency is high, treating capacity is big, pressure drop is low etc..Structured packing lacks Point is that anti-blocking is poor.When there is fouling risk, as contained solid particle, easily into the fluid in fluid-fluid contact arrangement Coking when easily polymerizeing, can generally be more likely to select larger (i.e. specific surface area the is smaller) structured packing of runner, this can To reduce fouling risk.In general, have fouling risk this application scenario when filler unit height than relatively low, generally in 100- 220mm, main purpose are to facilitate flushing and dismounting.But when in the bigger occasion of fouling risk, commonly regular is filled out The use of material is restricted, because structured packing component may block due to fouling is serious, influences normally to produce.
Industrially there is a kind of filler grid packing, grid packing is to be composed with bar element body through certain rule , there are multiple structural forms.The structure of grid packing is usually high opening rate, high-throughput, has certain anti-stifled ability, but imitates Rate is than relatively low.The each filler unit height of grid packing is generally than relatively low, generally in 54-70mm.
A kind of structured packing is currently known, under critical conditions, the performance of anti-blockage of structured packing can be improved.Its main skill Art scheme is that a gap is left between corrugated plate, and therefore reduces fouling risk.According to open source information, this kind of filler product Cell height is generally in 138mm, and this cell height has been greatly improved to reduce installation and take-down time.
Utility model content
However, in above-mentioned prior art, gas may be made to be more likely to flow through these gaps, so as to filled out to gas-liquid Expect that the mass transfer on surface is weakened, influence mass-transfer efficiency.
In addition, the risk of the fouling of structured packing is also related with interface point in structure, interface point is more, and fouling risk is got over Greatly.Through further furtheing investigate, this interface point except the interface point between the adjacent two panels in each unit of structured packing, The interface being also between two successive unit of structured packing.Particulate matter or coking and scaling in fluid are easier handing over Junction is accumulated, and liquid is also easily accumulated at interface.Interface point is more, and the risk of fouling is bigger.Other two is in succession The structure on interface between unit of structured packing is many except interface point, and some passages become very small, this causes The passage that fluid flows through becomes very little, and the particulate matter or coking in fluid are easy in this zone-accumulation, and the risk of fouling is big It is big to increase.
