Description
Technical field
The present invention relates to a kind of liter gas liquid trap for gas liquid reaction tower, in particular to a kind of shutter rises gas liquid collecting
Device.
Background technique
The gas liquid reaction tower in the fields such as chemical industry, environmental protection is sometimes using liter gas liquid collector, such as single column Two-way Cycle wet process cigarette
Flue gas can be divided into upper circulation by liter gas liquid collector and the lower area circulation Liang Ge, lower loop slurry are lower by desulfurization technique
PH value is conducive to the dissolution of lime stone and the crystallization of gypsum, can improve gypsum oxidation effectiveness, obtains the gypsum of high-quality, while right
Flue gas into absorption tower is pre-processed, and the SO in processing flue gas is reduced2, dust, HCl, HF content, be conducive to mitigate
The processing load of upper circulation, and the higher pH value of upper loop slurry can reach higher desulfuration efficiency.It is de- with conventional single cycle
Sulphur absorbs tower process and compares, and in single column Two-way Cycle, each circulation is independent control, is easy to optimize and quickly adjust, energy
Significantling change for sulfur content and load is adapted to, is easier to realize minimum discharge, is had the characteristics that energy saving, efficient.
Currently, the liter gas liquid collector on single column Two-way Cycle wet flue gas absorption tower generally uses dish, liquid trap bottom with
Slurries recovery tube is connected.Flue gas is entering top uptake zone by the ring section between liquid trap and absorption tower in absorption tower,
Absorption tower wall on the top of liquid trap has contraction section constraint loop slurry to be largely pooled to slurries liquid trap, avoids recycling
Slurries are directly sprayed to lower part purification cooling zone, improve the utilization rate of loop slurry.But since flue gas is simply by absorption tower wall
Annular space between liquid trap enters uptake zone, causes flue gas excessively high by the flow velocity in annular space section, and flue gas flow rate is unevenly distributed,
It is excessive to the loop slurry impact flow-disturbing of spray, slurries are influenced to the absorption efficiency of sulfur dioxide in flue gas, and excessively high gas velocity is very
Extremely slurries are carried under one's arms to demister.Chinese patent (patent No. 2016105157876.6) mentions a kind of multilayer dish liquid trap, should
The entrance section product of invention flue gas increases, and flue gas flow rate is evenly distributed, and the flow velocity of overcurrent flue gas reduces, and holds under the arm to lime stone slurry
Band effect reduces, and desulfuration efficiency is high, but there may be slurries to leak, needs to occupy the defect of biggish tower height degree for the liquid trap.
Chinese patent (patent No. 201420698052.6) mentions a kind of cascade type liquid collector, which designs simple, resistance
Lose small, gas flowfield be evenly distributed, liquid collector whole height reduce, upper circulated sprinkling layer installation site reduce, system warp
Ji property improves, but liquid collector production and installation are more troublesome, also relatively high to the installation requirement of leaf grating.In addition, at present absolutely
The most of separation for rising gas liquid trap and not having gas-liquid separating function and causing to realize upper and lower two-stage slurries well.
Summary of the invention
Cannot have for the liter gas liquid collector of existing gas liquid reaction tower there are slurries leakage, without gas-liquid separating function
Effect ground realizes the separation of two-stage slurries up and down, needs to occupy biggish tower height degree, production and installs relatively complicated problem, provides
A kind of novel liter of gas liquid collector that can overcome problem above and defect.
Goal of the invention of the invention is: the present invention provides a kind of liter gas liquid collector for gas liquid reaction tower, passes through
Using a liter gas cap, connecting tube, liquid collecting partition, groove and liquid discharge tube, there is the distribution of more uniform gas flowfield, reduce gas
Flow resistance, the advantages of avoiding slurries from leaking.Meanwhile the configuration of the present invention is simple, production install, are easy to maintain, help to improve
Gas-Liquid Absorption effect.
The present invention includes rising gas cap, connecting tube, liquid collecting partition, groove and liquid discharge tube.It rises between gas cap and connecting tube
By flanged joint, connecting tube lower weld is on liquid collecting partition, liquid collecting partition and the aperture of connecting tube connecting portion.Gas is under
Liquid collecting partition is passed sequentially through on and, connecting tube, rises gas cap, is flowed out obliquely by the gap between the blade of louver window of liter gas cap,
And the drop in overhead gas is contacted with the moisture film risen on gas cap cover board and blade of louver window, formation drop is low or along blinds
In the trickling to liquid collecting partition of window blade, groove is then flowed to, then be discharged by liquid discharge tube by groove.
Further to separate droplet from bottom to top, gas-liquid separation pipe can be installed below liquid collecting partition.Gas-liquid separation pipe,
Connecting tube rises the gas passage formed between gas cap from bottom to top.Gas-liquid separation bottom of the tube has spiral-plate leaf, and gas enters gas
Strong rotation is formed when liquid separating pipe, centrifugal movement makes the moisture film on droplet and gas-liquid separation tube cylinder inner wall in gas
Contact has defogging effect；Drip ring blocks moisture film and moves upwards, and forms drop and drip downwards.Liquid in overhead gas
Drop drops on a liter gas cap, liquid collecting partition and groove downwards, final liquid discharge tube discharge.Liquid collecting partition may be designed to inclination shape
Formula makes liquid flow to side to cancel groove, in order to the discharge of liquid.
The spiral-plate leaf quantity of gas-liquid separation bottom of the tube installation of the present invention is 2 ~ 20.
Of the present invention liter of gas cap cover board and flanged plate are regular hexagon, and muscle is installed between cover board and flanged plate
Plate installs blade of louver window between gusset and gusset, the blade of louver window quantity in each side direction of regular hexagon is 2 ~ 8
It is a, blade of louver window to a liter gas cap center deflection, blade of louver window with 20 ° ~ 60 ° of horizontal direction angle.
The advantages of a kind of shutter for gas liquid reaction tower of the invention rises gas liquid trap is:
1, the present invention can efficiently collect the drop in overhead gas；
2, the present invention can make gas uniformly across holding gas liquid reaction tower gas flowfield is uniform；
3, present invention may apply to the gas liquid reaction towers of major diameter；
4, when present invention lower section installation gas-liquid separation pipe, two-stage slurries separation up and down can be better achieved；
5, the present invention rises between gas cap and connecting tube, is all made of and is bolted between each gas-liquid separation pipe, installs, replaces
It is quick and convenient.
