Description
Technical field
The utility model belongs to chemistry or the biological cleaning field of waste gas, is specifically related to a kind of tail gas absorber liquid distribution device.
Background technology
White carbon black production device mainly utilizes chlorosilane to carry out high-temperature hydrolysis in oxyhydrogen flame, obtained silica (white carbon) after gas solid separation, in course of reaction, create a large amount of residual exhausts, by acid, the Alkali absorption tower of exhaust system, after utilizing liquid caustic soda washing, neutralization, discharge air.In production, often because absorption tower absorptivity is low, gas-phase pressure drop is excessive, cause system to occur liquid flooding, flooding and stifled tower phenomenon, meanwhile, acid absorption rate is on the low side, liquid caustic soda consumption is increased, causes vacuum pump system heavy corrosion, cause economic loss.
The tail gas absorber of packing type mainly comprises tower body, liquid distribution structure, packing layer structure, packing support device etc.When general packed tower ejecting liquid flows downward along packing layer, the trend of all oriented tower wall flowing, causes wall stream to increase, filler body flow reduces, finally have impact on the uniformity of fluid along tower cross-sectional distribution, occurred serious wall stream effect in actual production process, reduced the absorptivity of tower.
Utility model content
For the defect that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of impact that can weaken wall stream effect and cause, and improves the tail gas absorber liquid distribution device of absorptivity.
For achieving the above object, the technical solution of the utility model is: tail gas absorber liquid distribution device, comprise tower body and liquid-distributing disk, wherein, multiple liquid-distributing disk is provided with in described tower body, the spacing of adjacent two liquid-distributing disks is less than 2.5m, also being provided with longitudinal section is frustum shape, and up big and down small distribution cone, all be equipped with the distribution cone be positioned at above corresponding liquid distributing pan in tower body from top to bottom after first liquid-distributing disk, be provided with in described tower body and distribute the erecting bed of boring peripheral surface inclined-plane and coordinating.
When adopting technique scheme, tail gas enters from the bottom on absorption tower, and discharge from top, tail gas absorption liquid enters from tower body top, first first liquid-distributing disk is entered, absorbing liquid is evenly distributed, liquid, in dirty process, has the trend of Xiang Tabi flowing, causes wall stream to increase gradually, filler body flow reduces, before liquid enters second liquid-distributing disk, first through distributing cone, up big and down small owing to distributing conical inner surface diameter, so the absorbing liquid near tower body sidewall to be collected to the middle part of liquid-distributing disk, thus realize reallocation.The utility model is provided with multiple liquid-distributing disk in tower body, and fold from second liquid distribution, be equipped with above each liquid-distributing disk and distribute cone, thus the liquid of wall stream is collected again and distributes, so just can weaken the impact that wall stream effect causes, thus improve absorptivity.
Further, the described lower limb distributing cone is upturned, and forms annular groove.Absorbing liquid so just can be avoided directly to wash away the liquid-distributing disk distributing cone below, and the time one is long, just easily causes liquid-distributing disk surface irregularity, thus affects liquid distribution effect.
Further, the described bottom distributing the ring groove part of cone is provided with outage.First absorbing liquid is accumulated in annular groove, is then discharged continuously by outage, and the fluid flow that each outage is discharged is less, also less to the power of washing away of liquid-distributing disk, so have protective effect to liquid-distributing disk.
Further, described liquid-distributing disk comprises disk body, liquid flooding weir, overflow pipe and air rising hole, and the bottom diameter of described distribution cone is less than the internal diameter on liquid flooding weir.In the whole influent downflow weir of the liquid that such distribution coning tower tray goes out, liquid major part is overflowed from overflow pipe, only has and can discharge from air rising hole on a small quantity, ensures ventilatory effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model tail gas absorber liquid distribution device embodiment;
Fig. 2 is the structural representation distributing cone in the utility model tail gas absorber liquid distribution device embodiment;
Fig. 3 is the profile distributing cone longitudinal section in the utility model tail gas absorber liquid distribution device embodiment.
Detailed description of the invention
Shown in composition graphs 1 and Fig. 2, a kind of tail gas absorber liquid distribution device, comprise tower body 1 and liquid-distributing disk 2, wherein, be provided with multiple liquid-distributing disk 2 in tower body 1, the spacing of adjacent two liquid-distributing disks 2 is 2m, also being provided with longitudinal section is frustum shape, and up big and down small distribution cone 3, in tower body 1, second liquid-distributing disk 2 is all equipped with the distribution cone 3 be positioned at above corresponding liquid distributing pan afterwards from top to bottom, is provided with and distributes the cone 3 peripheral surface erecting bed that inclined-plane coordinates in tower body 1.
As Fig. 2 and 3, the lower limb distributing cone 3 is upturned, and forms annular groove 31.Absorbing liquid so just can be avoided directly to wash away the liquid-distributing disk 2 distributed below cone 3, and the time one is long, just easily causes liquid-distributing disk 2 surface irregularity, thus affects liquid distribution effect.
The bottom distributing annular groove 31 part of cone 3 is provided with outage 32.First absorbing liquid is accumulated in annular groove 31, is then discharged continuously by outage 32, and the fluid flow that each outage 32 is discharged is less, also less to the power of washing away of liquid-distributing disk 2, so have protective effect to liquid-distributing disk 2.
Liquid-distributing disk 2 comprises disk body, liquid flooding weir, overflow pipe and air rising hole, and the bottom diameter distributing cone 3 is less than the internal diameter on liquid flooding weir.In the whole influent downflow weir of liquid that such distribution cone 3 flows out, liquid major part is overflowed from overflow pipe, only has and can discharge from air rising hole on a small quantity, ensures ventilatory effect.
Specific works principle:
As shown in Figure 1, tail gas enters from the bottom on absorption tower, and discharge from top, tail gas absorption liquid enters from tower body 1 top, first first liquid-distributing disk 2 is entered, absorbing liquid is evenly distributed, liquid is in dirty process, there is the trend of Xiang Tabi flowing, wall stream is caused to increase gradually, filler body flow reduces, before liquid enters second liquid-distributing disk 2, first through distributing cone 3, up big and down small owing to distributing cone 3 inner diameter, and lower end forms annular groove 31, outage 32 is circumferentially provided with bottom annular groove 31, absorbing liquid is discharged from the outage 32 bottom annular groove 31, be collected in the liquid flooding weir of liquid-distributing disk 2, accumulate in liquid flooding weir, and finally overflow from overflow pipe, thus realize reallocation.
Above is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
