Background technology
The gas distributor often using in rectifying column in prior art, because structural design is unreasonable, causes tower bottom first segment packing layer to produce gas bias current and reduces gas-liquid distribution effect; Even also have some enterprises to suffer from and there is no suitable gas distributor, and be chosen in, in tower, do not use gas distributor.According to relevant industries codes and standards, tower more than general φ 1500mm all must adopt gas distributor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, gas distributor at the bottom of a kind of tower simple in structure, ingenious, rational is provided, this distributor can make gas not wander off in tower, and satisfied load enters packing layer and carries out gas-liquid exchange, reaches equally distributed object.
The technical scheme providing according to the utility model: gas distributor at the bottom of a kind of tower, comprise base plate, described base plate middle through-hole place is fixed with ventilation bracing ring, ventilation bracing ring upper surface is welded with some gas-liquids and receives expansion swash plate, and adjacent two gas-liquids are received to expand between swash plate and are provided with connecting plate, described gas-liquid is received and is expanded swash plate top and be welded with connection trim strip, also uniform on described base plate two liquid flooding holes is set, and liquid retaining ring is welded in plate upper surface corresponding to the outer ring in described liquid flooding hole.
As further improvement of the utility model, described connection trim strip has three, and three connection trim strips are all perpendicular to gas-liquid receipts expansion swash plate, wherein occupy middle connection trim strip and pass ventilation bracing ring centre of surface.
As further improvement of the utility model, described connecting plate is received the plate face that expands swash plate perpendicular to gas-liquid.
As further improvement of the utility model, described gas-liquid is received expansion swash plate and is comprised plate body, and plate body upper end has a kink perpendicular to plate body, and plate body lower end has a junction, and forms dovetail groove between this connecting portion and plate body.
As further improvement of the utility model, between described base plate and tower wall, be provided with body passage.Increased effective annular gas passage, the full tower of gas is distributed.
The utility model compared with prior art, advantage is: the utility model is simple and practical, resistance is little, by adopting gas-liquid to receive to expand swash plate to realize not only to collect the liquid getting off above but also the many-side to tower spreads the gas of rising, effective uprising gas in retention tower, flowing into tower bottom after the liquid collection declining from base plate liquid flooding hole, gas-liquid is fully contacted simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that in the utility model, gas-liquid is received the structural representation that expands swash plate.
Fig. 3 is use status architecture schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Fig. 1 ~ 3, comprise that connection trim strip 1, ventilation bracing ring 2, liquid retaining ring 3, base plate 4, back-up block 5, connecting plate 6, gas-liquid receipts expand swash plate 7, plate body 7-1, kink 7-2, connecting portion 7-3, dovetail groove 7-4, liquid flooding hole 8, tower body 9, gas passage 10 etc.
As shown in Fig. 1 ~ 3, gas distributor at the bottom of a kind of tower of the utility model, comprise base plate 4, described base plate 4 middle through-hole places are fixed with ventilation bracing ring 2, ventilation bracing ring 2 upper surfaces are welded with some gas-liquids and receive expansion swash plate 7, and adjacent two gas-liquids are received to expand between swash plate 7 and are provided with connecting plate 6, described gas-liquid is received expansion swash plate 7 tops and is welded with connection trim strip 1, also uniform on described base plate 4 two liquid flooding holes 8 are set, liquid retaining ring 3 is welded in base plate 4 upper surfaces corresponding to the outer ring in described liquid flooding hole 8, liquid retaining ring 3 plays the effect of gear liquid, do not make flow direction tower body 9 inwalls, and the rising of assurance gas is not obstructed.Between described base plate 4 and tower wall, be provided with body passage, increased effective annular gas passage, the full tower of gas is distributed.
As shown in Figure 2, described connection trim strip 1 has three, and three connection trim strips 1 are all perpendicular to gas-liquid receipts expansion swash plate 7, wherein occupy middle connection trim strip 1 and pass ventilation bracing ring 2 centre of surfaces.
Described connecting plate 6 is received the plate face that expands swash plate 7 perpendicular to gas-liquid.
As shown in Figure 3, described gas-liquid is received expansion swash plate 7 and is comprised plate body 7-1, and plate body 7-1 upper end has a kink 7-2 perpendicular to plate body 7-1, and plate body 7-1 lower end has a junction 7-3, and forms dovetail groove 7-4 between this connecting portion 7-3 and plate body 7-1.
As shown in Figure 1, use principle of the present utility model is as follows: in tower body 9 inwalls along the uniform some back-up blocks 5 that arrange of same periphery, the utility model is positioned on described back-up block 5, guarantee to leave gap so that form gas passage 10 between base plate 4 and tower body inwall, make gas same upwards orderly along tower body 9 inwall one circles, make to be full of under packing layer the gas of rising, enter packing layer and make to keep uniform gas to rise in packing layer, carry out gas-liquid contact, reach equally distributed object.
