Technical field
The utility model is related to a kind of chemical production equipment, and in particular to the situation of gas-liquid phase reaction or absorption contact in a kind of Chemical Manufacture.Belong to gas-liquid mass transfer technical field of chemical.
Background technology
Plated tower is gas-liquid heat-transfer, the common equipment of mass transport process.The flow behavior of gas-liquid two-phase has material impact to the heat transfer of plated tower, mass-transfer efficiency in tower.Conventional tower considers the engineering factor of gas-liquid mass transfer (contact) equipment, pursues specific surface area as big as possible by transforming the tower plate structure in tower body or installing filler, promotes gas-liquid mass transfer.Usually, the plated tower run in Chemical Manufacture is that liquid is flowed downward by downspout, enters from the gap between the downspout and descending trays of special setting and horizontal through descending trays, so flows to tower reactor always repeatedly.Liquid layer thickness on column plate is determined by the height of exit weir, and gas enters through liquid layer in version and realize heat transfer, mass transfer then from bottom to top by the perforate on pedal.In this traditional plated tower, the column plate in plated tower is connected on tower section, and contains king-post, is that gas liquid interfacial area is reduced, plated tower complex structure.
The content of the invention
The problem of the purpose of this utility model is and is directed to above-mentioned is directly fixed on tower wall there is provided a kind of column plate, or is fixed on the crossbeam stretched out by tower wall, does not contain king-post, and on the premise of big liquid holdup is ensured, expands the plated tower of the contact area of liquid or gas.
To solve the above problems, the utility model is to take following technical scheme to realize：A kind of plated tower, including tower body, column plate A, column plate B, tower wall interlayer outer wall, gasket seal, crossbeam, gas feed, liquid outlet, low head, upper cover, liquid inlet, gas vent, tower section, upper tooth weir, lower tooth weir, connector and sewage draining exit, the column plate A is fixed on tower body, and the column plate B is fixed on the crossbeam of tower wall stretching.
The upper surface of the column plate A or column plate B are provided with upper tooth weir.
The upper high h in tooth weir of the column plate A or column plate B1=30-200mm。
The lower surface of the column plate A or column plate B are provided with lower tooth weir, the high h of distributed tooth2=5-200m。
Hole is provided with column plate A or column plate B the midplanes area, aperture is φ=2-10mm, quantity 1-5.
The beneficial effects of the utility model are：Column plate is directly connected in tower wall, or is fixed on the crossbeam stretched out by tower wall, does not contain king-post.Single-unit tower body can set multi-disc column plate, reduce the quantity of tower section, and economic benefit is significantly improved.Tooth weir on the sawtooth of different height can be designed, so as to ensure suitable liquid holdup according to the process characteristics of detailed programs on column plate；The tower has the changes in flow rate scope of gas and liquid --- and operating flexibility is big, will not produce and cause liquid flooding and the phenomenon of leakage due to gas and fluid flow change, cause tower body cisco unity malfunction；Gas-liquid contact bubbling only on liquid curtain, reaction tower SR is especially small；Column plate makes and simple to operate, the characteristics of serial material possibility deep-etching being adapted to be directly prepared into the metal material or resisting and acidproof ceramic material that are adapted with process stream.
