Abstract
The utility model discloses a conical degree spiral filling; wherein the inner side of a hollow cone is provided with a spiral groove, the bottom of the spiral groove is provided with a vent hole; the different materials can be made into the regular or bulk filling applied to various industrial filled towers. The utility model overcomes the defects of that the existing industrial tower filling has the small liquid holdup, small operating flexibility and small separating factor and is easy to be blocked; compared with the conventional tower filling, the utility model has the same tower pressure drop, and the operating load of the tower can increase 40 to 60 percent; under the same specific surface area, the effective mass transfer area can increase 30 to 40 percent, and the mass transfer efficiency is greatly larger than the existing filling; under the condition of the same spray density, the pressure drop of the filling layer per meter averagely decreases 40 to 50 percent, and the relatively stable tower pressure drop can be maintained within the range of a wider operation load; the filling has a stronger self-cleansing capacity, and isn't easy to block and applied to the operation of the high viscidity matter.
Description
Technical field
The utility model relates to the filler that the industrial filler tower is used.
Background technology
The filler that present industrial filler tower is used has dumped packing and structured packing, and dumped packing has advantages such as the processing of being easy to, convenient filling, low, the difficult obstruction of cost of manufacture; Structured packing has then that specific area is big, voidage is big, pressure drop is low, efficient is high, enlarge-effect is little, is convenient to advantage such as industrialization, but that both weak points are liquid holdups is little, operating flexibility is little, and separating factor is little, easily stops up.Solve the problem of present existence, at first to understand its main influence factor: the 1. a pair of often contradiction of specific area and voidage, if obtain than bigger serface, just must increase the filler quantity in the unit packing volume, its result just must make the voidage of packing layer descend, and vice versa; 2. the effective mass transfer area in the tower mainly comes from filling surface, so filler must have higher specific surface area just can obtain higher mass transfer area; 3. gas-liquid two-phase is vertical countercurrent basically in the packing layer, so the packing layer voidage is big more, and flow resistance is just more little.So generally the evaluation criterion to the industrial tower filler is that specific area is big, voidage is big and packing factor is little, cost is low.4. the separation principle of gas-liquid two-phase is to utilize the gravity effect of the earth that the gas-liquid two-phase that has the greater density difference can be separated rapidly, and its separating factor then must be subjected to the restriction and the constraint of acceleration of gravity.5. in tower, the flow through gas-liquid two-phase counter current contacting of packing layer, therefore the flow resistance that produces is bigger; 6. gas-liquid two-phase counter current contacting in the packing layer space increases the liquid phase flow and can increase the localized accumulated of liquid phase, reduces the packing layer voidage, causes liquid flooding in the tower easily, so liquid holdup is less; 7. have a large amount of dead angles in the packing layer, liquid phase stream is to disorderly and unsystematic, and liquid-gas ratio is less, so liquid does not have the self-cleaning effect substantially to filling surface, thereby solid particle easily causes the obstruction of packing layer easily in filling surface deposition and accumulation.
The utility model content
The purpose of this utility model provides that a kind of liquid holdup is big, operating flexibility is big, separating factor is big, mass-transfer efficiency is high, and the little tapered spiral filling of pressure drop.
The purpose of this utility model realizes in the following way: a kind of tapered spiral filling is characterized in that: on the medial surface of hollow cone spiral sluice is arranged, on the bottom of spiral sluice passage is arranged.
Spiral sluice on the medial surface of hollow cone is the multi-head spiral chute.
Spiral sluice on the medial surface of hollow cone is the single head spiral sluice.
The spiral sluice section is a circular arc, or other geometries.
Passage on the spiral sluice bottom is interrupted passage, makes tapered spiral filling seem the basket shape.
Passage on the spiral sluice bottom is continuous passage, makes tapered spiral filling seem the pagoda spring shape.
The longitudinal section of hollow cone is a waveform.
The utility model has overcome that existing industrial tower filler liquid holdup is little, operating flexibility is little, and separating factor is little, easily defective such as obstruction. and the utility model is compared with conventional tower packing: identical tower pressure drop, the operational load of tower can improve 40～60%; Under identical specific area, effectively mass transfer area can improve 30～40%, and mass-transfer efficiency is much larger than existing filler; Under identical sprinkle density situation, the pressure drop of every meter packing layer is far below conventional tower, and in wider operational load scope, can keep metastable tower pressure drop; Filler has stronger self-cleaning ability, is difficult for stopping up, and is applicable to full-bodied system operation.Compare with the θ ring filler, its spotting out gas speed on average will exceed 8.76%, and moving liquid holdup is average bigger by about 31% than θ ring filler, and the spotting out pressure drop will hang down 45.38%; Compare with the Raschig ring filler, its advantage is more obvious, identical tower pressure drop, and spotting out gas speed on average will exceed 2～3 times; And simple in structure, easy processing, with low cost; Can adopt different materials to be made into regular or dumped packing, be applicable to various industrial filler towers, also can be used for association areas such as environmental protection protection and biochemical industry.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
