Description
Technical field
The invention belongs to chemical tower internals field, more particularly, to a kind of continuous in relation to the gas-liquid in absorption process
The big liquid holdup ejection-type absorption tray of contact mass transfer.
Background technology
It, will be each in admixture of gas commonly using the method absorbed in the productions such as oil, chemical industry, pharmacy, environmental protection
Component is detached.Absorption is to detach admixture of gas using the difference of solubility, with absorbent by gas can melt into
Divide dissolving in the liquid phase, undissolvable component retains in the gas phase, achievees the purpose that separation.
Mixed gas is carried out using the separation of absorbent generally in absorption tower, and wherein plate column is widely used.It is board-like
Tower technology is by continuous development and innovation, from traditional column plate, such as bubble-cap, float valve, sieve plate, to there is vertical sieve tray ejection-type
Column plate, column plate technology make great progress.The processing capacity of traditional column plate is small, efficiency is low and pressure drop is big, high energy consumption, and
New Vertical Sieve Tray New-VST, three-dimensional continuous mass transfer column plate LLCT and the spray researched and developed on the basis of LLCT developed in recent years
Emitting column plate etc., processing capacity, efficiency, operating flexibility, anti-blocking etc. are all significantly improved, in the board-like of absorptive unit
In tower, what ineffective gas-liquid contact mass transfer part will try to realize and be operated under high liquid layer, to be supplied to gas-liquid two-phase enough
Time of contact realizes the dissolving of soluble gas and is detached with insoluble gas, but under high liquid layer, column plate resistance drop must increase
Greatly, gas-liquid contact time long enough is found and anode drop is relatively low, and the high gas-liquid contact mass transfer part of separative efficiency is reaction
Rectifiying plate urgent problem.
Invention content
In view of this, the invention is directed to a kind of simple in structure, it is particluarly suitable for operating under the conditions of high liquid layer, inhales
It requires to use in the longer process system of gas-liquid contact time during receiving, the jet tray of high efficiency low pressure drop, in solution
State problem.
In order to achieve the above objectives, the technical solution of the invention is realized in：
A kind of big liquid holdup ejection-type absorption tray, including offer the column plate of multiple air rising holes and be arranged in the column plate
On the jet cover each installed at the position of the air rising hole of correspondence；Between the bottom end of the jet cover and the column plate there are
Bottom gap, further include it is multiple be connected to respectively with each air rising hole setting be located at the jet cover inner cavity and with the jet cover
Between there are the riser in gap, the riser is truncated cone-shaped structure, upper and lower open at both ends, and end face internal diameter is less than it thereon
Lower face internal diameter, the bottom end of the riser and the edge of the air rising hole are seamlessly connected.
Further, the lower face internal diameter of the riser is than path length 10-50mm in upper surface, the lower end of the riser
Face internal diameter is equal with the diameter of the air rising hole.
Further, the top of the riser is also associated with the second riser of cylindrical annular structure, described second liter
The bottom edge of tracheae is connect with the tip edge of the riser, internal diameter and the riser of second riser (6)
Upper surface internal diameter is equal.
Further, the tip edge of second riser is wavy shaped configuration.
Further, the jet cover includes cover body, set on the head cover on the cover body top and set on the cover body bottom
Fixing leg；The jet cover is fixedly connected by the fixing leg with the column plate, the bottom end of the cover body with it is described
There are the bottom gaps between column plate；The faceshield side wall upper end is uniformly provided with multiple spray-holes；The cover body and the head cover
Between offer skylight.
Further, the cover body is truncated cone-shaped structure, and end face diameter is less than its lower face diameter thereon.
Further, the lower face diameter of the cover body is longer 10-50mm than upper surface diameter.
Compared with the existing technology, the big liquid holdup ejection-type absorption tray described in the invention has the advantage that：
(1) during the anode drop of plate column is mainly reflected in lifting liquid by gas, kinetic energy factor makes gas
At resistance, under high liquid layer operating condition, gas-liquid contact and hold in the palm rise during, liquid layer is excessively high to cause anode drop excessively high, this
Jet cover described in innovation and creation is internally provided with the riser for the truncated cone-shaped structure being connected to air rising hole, gas phase through riser into
Enter in jet cover, contacted with liquid phase on the top of riser, improves contact position of the gas-liquid two-phase on column plate, reduce gas
Body needs to hold in the palm the thickness for rising liquid level, is ensuring that the while of having enough reaction contact times effectively reduces anode drop；
(2) jet cover described in the invention and riser are the truncated cone-shaped that upper surface diameter is less than lower face diameter
The lower face diameter of structure, riser is longer 10-50mm than upper surface diameter, and lower face internal diameter is equal with the diameter of air rising hole, rises
The position that the height of tracheae is opened up according to the height of jet cover and spray-hole determines, with existing New-VST jetting type tower plates phase
Than the gas velocity of gas gradually being increased during being sprayed to head cover after lifting liquid by gas, due to ejection-type jet cover
Ejector principle is the high mass transfer efficiency under high gas velocity, and increasing gas velocity can be such that gas-liquid mixture is ejected from spray-hole and skylight
When crush more thoroughly, to make gas-liquid separation more thoroughly；The lower face diameter of riser is longer 10- than upper surface diameter
50mm, lower face internal diameter is equal with the diameter of air rising hole, what the height of riser was opened up according to the height and spray-hole of jet cover
Position determines；
(3) the second riser described in the invention is set to the top of riser, by the riser of truncated cone-shaped structure
The gas of outflow uniformly flows out in the second riser, simultaneously because the tip edge of the second riser is waveform, Ke Yijia
Big gas liquid interfacial area；
(4) ejection-type absorption tray described in the invention is simple in structure, easily fabricated, stable operation, failure rate are low,
Efficient 5-10% or so of the mass-transfer efficiency compared with New-VST jetting type tower plates.
