Description
Technical field
The present invention relates to a kind of chemical production equipment, be specifically related to the liquid phase reaction in a kind of Chemical Manufacture or absorb situation about contacting.Belong to the gas-liquid mass transfer technical field of chemical.
Background technology
Gas absorbing device is the common equipment of gas-liquid heat-transfer, mass transport process.The flow behavior of gas-liquid two-phase has material impact to heat transfer, the mass-transfer efficiency of plate column in the tower.Conventional gas absorption plant---tower is considered the engineering factor of gas-liquid mass transfer (contact) equipment, by transforming the tower plate structure in the tower body or filler being installed being pursued large as far as possible specific area, promotes gas-liquid mass transfer.Usually, the plate column that moves in the Chemical Manufacture is that liquid is flowed downward by downspout, from the downspout of special setting and the slit between lower floor's column plate enters and level is passed lower floor's column plate, so repeatedly flows to tower reactor always.Liquid layer thickness on the column plate is determined that by the height of exit weir gas enters and passes an edition upper liquid layer and realize heat transfer, mass transfer then from bottom to top by the perforate on the pedal.In this traditional plate column, all be cambered plate in the plate column, carry out in the contact of the gas-liquid two-phase liquid layer onboard, gas is to overcome simultaneously liquid gravity on the column plate, flaggy resistance and surface tension by column plate.In addition for mass transfer apparatus between solution type liquid and the gas, often because liquid holdup is inadequate, may separate out solid in the process, blocking portion passage even obstruction make whole tower and can not adapt to.Plate column equipment liquid holdup commonly used is often little, also is subject to the restriction of operating flexibility scope, produces easily solid and stops up.The present invention adopts gas absorbing device, prolongs the haptoreaction time of liquids and gases, and than larger gas-liquid contact area is provided in the identical cylinder tower diameter, simple in structure, and placement occupies little space.
Summary of the invention
The objective of the invention is provides a kind of device for above-mentioned problem, under the prerequisite that guarantees large liquid holdup, provides mass transfer area large, and resistance is little, and mass-transfer efficiency is relatively high, gas absorbing device simple in structure.
For addressing the above problem, the present invention takes following technical scheme to realize:
A kind of gas absorbing device comprises sealing, liquid-inlet, gas vent, tower joint, seal washer, column plate, observation panel, tower wall interlayer outer wall, gas feed, tower body, liquid outlet and lower sealing, described gas absorbing device is comprised of at least two tower bodies, described tower body is the prolate shape, connects by pipeline between described tower body.
Described pipe diameter is slightly larger than the diameter of gas feed or gas vent, and described pipe diameter is slightly larger than the diameter of liquid-inlet or liquid outlet.
Described column plate upper surface is provided with the tooth weir, upper height of weir h
1=30-200mm, h
2=3-180mm.The lower surface of described column plate is provided with the lower tooth weir, distribution tooth depth h
3=5-200m.
The high h of described tower body
1=1.5m.
The invention has the beneficial effects as follows: the gas feed by several prolate type tower bodies is that tubular structure is connected with gas vent or liquid-inlet with liquid outlet, so that gas-liquid contact area change, resistance is little, mass-transfer efficiency improves, and institute takes up space less, simple to operate, and can carry out continuously GAS ABSORPTION.
Tower body absorption plant of the present invention is simple in structure, makes with simple to operate, can be in order to use the metal material that adapts with process stream or resisting and acidproof ceramic material directly to make to adapt to the characteristics that this series material may deep-etching.
