Abstract
The utility model discloses a kind of absorption towers with novel trunnion pallet, it include: spraying layer, demister and trunnion pallet, wherein the spraying layer is arranged in above the gas inlet on absorption tower, the smoke outlet above the spraying layer close to absorption tower is arranged in the demister, and the trunnion pallet is arranged below the spraying layer；The trunnion pallet includes tray body, multiple trunnion holes is provided in the tray body, each trunnion hole is variable diameter hole, and the round diameter of the upper surface in the variable diameter hole is less than the round diameter of its lower end surface.The utility model increases gas-liquid perturbation action, reduces temperature because of the design of trunnion pallet, forms the bubble level for reducing pH value, improves desulfuration efficiency.
Description
Technical field
The utility model relates to environment protection fields, particularly relate to a kind of absorption tower with novel trunnion pallet.
Background technique
Wet desulphurization is how current most widely used sulfur removal technology improves de- with the proposition of minimum discharge standard
Sulphur efficiency becomes the hot topic of environmental protection industry (epi).Void tower flow field is simulated by CFD it is found that flue gas enters after absorption tower to generate
Whirlpool causes Ta Nei flue gas branch uneven, and the arrangement of spraying layer is usually to be evenly arranged, this just will appear exhaust gas volumn and slurry
The unmatched situation of liquid measure, exhaust gas volumn is more and slurries will cause desulfuration efficiency reduction less, and exhaust gas volumn lack slurries mostly it will cause
The waste of slurries.So smoke distribution and grout distribution in absorption tower should reach unanimity to improve desulfuration efficiency.
Therefore, the inventor of the utility model needs to conceive a kind of new technology to improve its problem.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of absorption tower with novel trunnion pallet.
The technical solution of the utility model is:
A kind of absorption tower with novel trunnion pallet, comprising: spraying layer, demister and trunnion pallet, wherein the spray
Drenching layer is arranged in above the gas inlet on absorption tower, and the flue gas above the spraying layer close to absorption tower is arranged in the demister
Exit, the trunnion pallet are arranged below the spraying layer；The trunnion pallet includes tray body, in the pallet sheet
Multiple trunnion holes are provided on body, each trunnion hole is variable diameter hole, and the round diameter of the upper surface in the variable diameter hole is small
Round diameter in its lower end surface.
Preferably, the percent opening of the trunnion pallet is between 10%-50%.
Preferably, the tray body is discoid, and material is stainless steel.
Preferably, the ratio between round diameter of trunnion hole upper and lower ends is between 1:2 to 1:20.
Preferably, the ratio between the round diameter at trunnion hole both ends is 1:10.
By adopting the above technical scheme, the utility model include at least it is following the utility model has the advantages that
Absorption tower described in the utility model with novel trunnion pallet, because trunnion pallet increases gas-liquid, disturbance is made
With, reduce temperature, form reduce pH value bubble level, so desulfuration efficiency can be greatly improved.
Detailed description of the invention
Fig. 1 is the structural schematic diagram on the absorption tower described in the utility model with novel trunnion pallet；
Fig. 2 is the top view of trunnion pallet described in the utility model；
Fig. 3 is the side view of trunnion pallet described in the utility model.
Wherein: 1. demisters, 2. spraying layers, 3. trunnion pallets, 4. trunnion holes.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1 to Figure 3, a kind of absorption tower with novel trunnion pallet 3 to meet the utility model, comprising:
Spraying layer 2, demister 1 and trunnion pallet 3, wherein the spraying layer 2 is arranged in above the gas inlet on absorption tower, the demisting
2 top of spraying layer is arranged in close to the smoke outlet on absorption tower in device 1, and the trunnion pallet 3 is arranged in the spraying layer 2
Lower section；The trunnion pallet 3 includes tray body, and multiple trunnion holes 4, each trunnion are provided in the tray body
Hole 4 is variable diameter hole, and the round diameter R1 of the upper surface in the variable diameter hole is less than the round diameter R2 of its lower end surface.
Preferably, the percent opening of the trunnion pallet 3 is between 10%-50%.
Preferably, the tray body is discoid, and material is stainless steel.
The ratio between round diameter of trunnion hole upper and lower ends is between 1:2 to 1:20.
Preferably, the ratio between the round diameter at trunnion hole both ends is 1:10.
The design in the variable diameter hole is so that be 10~25m/s by flue gas instantaneous velocity after trunnion hole.
It is the conventional design on absorption tower additionally, due to demister 1, spraying layer 2 etc., therefore the present embodiment does not repeat this, this
Field technical staff should know.
The principle that trunnion pallet 3 improves desulfuration efficiency in the present embodiment is: trunnion pallet 3 is from the appearance as honeycomb
Coal, the gap unlike honeycomb briquette through flue gas are trunnion shapes.Due to the obstruction of pallet, flue gas enters whirlpool after absorption tower
Whirlpool can disappear, and be in equally distributed state.Since the gap of trunnion pallet 3 is diminishing, speed when flue gas passes through
It will increase, further increase gas-liquid disturbance, break through established acid droplet, form fresh surface and continue absorbing reaction；
In addition, being apparent from according to conservation of energy principle, the flue-gas temperature after flow velocity increase can be reduced, this is beneficial to the absorption of SO2, simultaneously
The evaporation for reducing moisture, to reduce water consume.On the other hand, slurries can form one layer of bubble level, pH value here on pallet
It is lower, be conducive to the dissolution of CaCO3, increase the residence time for absorbing slurries.To sum up, it is disturbed because trunnion pallet 3 increases gas-liquid
Movement is used, and temperature is reduced, and the bubble level for reducing pH value is formd, so desulfuration efficiency can be greatly improved.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with features of novelty.
