Description
Technical field
The utility model belongs to the gas-liquid contanct equipment using in petroleum chemical industry, and what be specifically related to is guide spray column plate.
Background technology
Column plate is rectifying in petroleum chemical industry, absorb, the separation equipment using in desorption process, wherein have a kind of column plate by horizontal column plate, down-flow plate, jet cover forms, horizontal column plate and down-flow plate are fixedly mounted in tower shell, down-flow plate and horizontal column plate and tower shell three form downspout, on horizontal column plate, be conventionally designed with the circular air rising hole of the formed objects of arranging by rule, jet cover is arranged on circular air rising hole by supporting leg, between the bottom of jet cover and horizontal column plate, leave end gap, this column plate is usingd between plate overhead as main mass transfer region, gas-liquid contact time and contact area are large, but because the top board of the jet cover of this column plate is enclosed construction, easily cause and build the pressure, cause pressure drop or resistance to increase, gas-liquid mass transfer efficiency is good not.
Summary of the invention
The purpose of this utility model is to provide guide spray column plate, and it is for building the pressure of solving that the existing column plate with jet cover exists, problem that gas-liquid mass transfer efficiency is bad.
The utility model solves the technical scheme that its technical problem adopts: this guide spray column plate consists of horizontal column plate, down-flow plate, jet cover, drainage trough, horizontal column plate and down-flow plate are fixedly mounted in tower shell, on horizontal column plate, be arranged with circular air rising hole, down-flow plate and horizontal column plate and tower shell three form downspout, jet cover is arranged on horizontal column plate by supporting leg, between the bottom of jet cover and horizontal column plate, leave end gap, the distribution mode of the circular air rising hole in jet cover surrounds is, centre bore is larger, and centre bore is evenly offered aperture around; There is top board jet cover upper end, is provided with Guide spray hole on top board, and Guide spray hole is surrounded with baffle ring around, sprays the rear end that cap is connected to baffle ring, sprays cap the baffle ring of its below is masked, and the front end that sprays cap and baffle ring forms jet; Drainage trough is arranged on horizontal column plate, between drainage trough and horizontal column plate, has space, and drainage trough is the cell body with an opening, and the openend of drainage trough is sitting on down-flow plate, and the jet cover on horizontal column plate all extend in drainage trough.
Beneficial effect:
In the utility model, on jet cover top board, be provided with unlimited Guide spray hole, can solve the problem that builds the pressure that jet cover brings; In addition, baffle ring can prevent that liquid from flowing back into jet cover from jet cover top board, improves plate efficiency; Take second place, the centre bore surrounding in interior circular air rising hole due to jet cover is larger, and it is around the aperture of evenly offering, and can make gas more equably by horizontal column plate, makes uprising gas more even, and gas-liquid mass transfer efficiency is high; Finally, the liquid phase that drainage trough hits cover ejection by injection concentrates in drainage trough, the openend of drainage trough is sitting on down-flow plate simultaneously, fluid after mass transfer flows to downspout from drainage trough openend, and the liquid flowing down from upper strata column plate is subject to stopping of down-flow plate, can only flow in jet cover, carry out mass transfer, heat transfer with gas phase, can not mix with the fluid of jet cover ejection, avoid backmixing of liquid phase, improve gas-liquid mass transfer efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the stereogram of drainage trough in the utility model.
Horizontal column plate 3 down-flow plate 4 downspout 5 jet cover 6 baffle rings 7 of 1 tower shell 2 spray circular air rising hole 10 supporting leg 11 top board 12 drainage troughs of cap 8 jet 9.
The specific embodiment
By reference to the accompanying drawings the utility model is described further:
As shown in Figure 1, this guide spray column plate is by horizontal column plate 2, down-flow plate 3, jet cover 5, drainage trough 12 forms, horizontal column plate 2 and down-flow plate 3 are fixedly mounted in tower shell 1, down-flow plate 3 forms downspout 4 with horizontal column plate 2 and tower shell 1 three, on horizontal column plate 2, have the circular air rising hole 9 of arranging by design rule, jet cover 5 is arranged on horizontal column plate 2 by supporting leg 10, 2 of the bottom of jet cover 5 and horizontal column plates leave end gap, the distribution mode of the circular air rising hole 9 in jet cover surrounds is, centre bore is larger, centre bore is evenly offered aperture around, the circular air rising hole 9 distributing like this can guarantee that uprising gas is uniformly distributed, be conducive to gas-liquid mass transfer and improve mass-transfer efficiency.
There is top board 11 the utility model jet cover upper end, on jet cover top board 11, be provided with Guide spray hole, Guide spray hole is surrounded with baffle ring 6 around, baffle ring 6 fixedly mounts along spray-hole top edge, injection cap 7 is connected to the rear end of baffle ring 6, spray cap 7 baffle ring 6 of its below is masked, spray cap 7 and form jet 8 with the front end of baffle ring, the direction of jet 8 is consistent with the liquid flow path direction on horizontal column plate.The liquid that baffle ring 6 can prevent from accumulating on top board 11 flows back into jet cover 5, improves plate efficiency.
Drainage trough 12 can be arranged on horizontal column plate 2 by pillar, 2 of drainage trough 12 and horizontal column plates have space, the liquid that upper strata column plate flows down flow in this space, the openend of drainage trough 12 is sitting on down-flow plate 3, the liquid that upper strata column plate flows down is subject to stopping of down-flow plate 3, can only flow in jet cover 5; Consult Fig. 2, drainage trough 12 is for having the cell body of an opening, and porose on drainage trough 12, the jet cover 5 on same layer column plate extend in drainage trough 12 through these holes, the fluid ejecting from jet cover 5 is injected into drainage trough 12, and can only flow to downspout 4 from the openend of drainage trough 12.
During work, liquid flows down from upper strata drainage trough 12, and flow into this layer of horizontal column plate 2 from downspout 4, uprising gas enters jet cover 5 from circular air rising hole 9, because being designed to centre bore, circular air rising hole 9 evenly offers aperture around, uprising gas distributes very evenly, to enter the lifting liquid in jet cover 5 from end gap, membrane, then together from jet 8 ejections, be ejected in drainage trough 12, realize gas-liquid separation, the liquid of ejection flows in downspout 4 and flows to lower one deck column plate, gas rises and enters last layer column plate, thereby reach the object of gas-liquid mass transfer and heat transfer.
