Description
Technical field
The utility model relates to a kind of spray synthetic tower, for utilizing liquid phase that synthetic tower makes that gas phase in the synthetic tower and small droplets are carried out the synthetic tower of cooling and absorbing, relate in particular to a kind of spray synthetic tower that hydrogen chloride gas and sulfur trioxide gas are mixed with liquid chlorine sulfonic acid that is used for.
Background technology
The synthesis material of chlorsulfonic acid is hydrogen chloride gas and sulfur trioxide gas, and for the manufacturer of domestic chlorsulfonic acid, the synthesis technique of chlorsulfonic acid does not all have great variation all the time.Patent No. ZL97112819.7 discloses the scheme that high concentration gas process that a kind of quilt generally adopts prepares chlorsulfonic acid, the preparation of pure sulfur trioxide gas wherein is provided, to send into the nicotinic acid absorption tower after the cooling of lower concentration sulphur trioxide unstripped gas, after absorbing, obtain free sulphur trioxide concentration and be 20～30% oleum, then oleum is sent into the vaporizer desorb.
Patent No. ZL02138609.9 discloses the synthetic high concentration cl sulfonic acid technology of a kind of lower concentration sulphur trioxide, point out high temperature section and the low-temperature zone of mixed gas through cooling separator, obtaining non-condensable gases and liquid is the chlorsulfonic acid crude product, this chlorsulfonic acid crude product and hydrogen chloride gas further react the acquisition finished product, and non-condensable gases is by parsing the hydrogenchloride recycle.
But, existing chlorsulfonic acid synthesis technique still possesses following shortcoming: 1, the gas chlorsulfonic acid that makes of sulphur trioxide and chlorine hydride mixed gas precursor reactant directly cools off and obtains the liquid chlorsulfonic acid, the gas chlorsulfonic acid that is not fully absorbed in the tail gas accounts for large percentage, the aftertreatment technology complexity; 2, the residence time weak point of mixed gas in synthetic tower influences rate of product transformation; 3, occupation area of equipment is big, and what the cooling of gaseous chlorine sulfonic acid was used is to use water-cooled water cooler, and volume is big, makes the synthetic tower one-piece construction not compact, and floor space is big.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of liquid phase of utilizing to carry out cooling and absorbing to mixing gas phase, and mixed gas residence time in tower is long, and rate of product transformation height, and the spray synthetic tower of volume compact are particularly useful for the preparation of chlorsulfonic acid.
The utility model solves the problems of the technologies described above the technical scheme of taking: a kind of spray synthetic tower, the synthetic tower lower housing portion is provided with inlet mouth and liquid outlet, the top is provided with the air outlet, be characterized in, be provided with middle filler, middle part skimmer, upper strata filler and top skimmer in the described synthetic tower from bottom to top successively, wherein, downwards the middle part skimmer of filler spray liquid and top skimmer by the liquid outlet UNICOM circulation feed flow of recycle pump and bottom.Of the present utility model one big characteristics are to be provided with packing layer in synthetic tower, the existence of filler makes that mixed gas mixed distribution in tower is more even, and the residence time is long, make unstripped gas fully synthetic.
Described liquid outlet is by one-level water cooler and middle part skimmer UNICOM feed flow, again by secondary coolers and top skimmer UNICOM feed flow.Water cooler is used to cool off the liquid phase resultant that liquid outlet obtains, and by the recycle pump circulated sprinkling, thereby cooling and absorbing, washing remain vapor-phase reactant and reactant small droplets in synthetic tower.
Be distributed with most temperature indicating devices on the described synthetic tower.
And on the basis of such scheme, described temperature indicating device is arranged on the middle and upper part of synthetic tower at least.The specific form of this temperature indicating device is used to be provided with heat indicator for be provided with most thermometer bosses on the synthetic tower housing, because synthesis temperature is very important in the preparation process, so thereby temperature indicating device is set to be adjusted temperature in the tower according to showing.
Described middle filler position is higher than the height of inlet mouth.
Described inlet mouth position is higher than the height of liquid outlet.
Described liquid outlet is arranged on synthetic tower lower part of frame side or bottom face.
The beneficial effects of the utility model are:
1, utilize liquid phase resultant circulated sprinkling cooling and absorbing vapor-phase reactant, and the further reactant small droplets in the circulated sprinkling washing gas, secondary spraying makes rate of product transformation high, nearly 100%;
2, abolish the water cooler of traditional water cooling vapor-phase reactant, use the water cooler of cooling fluid phase resultant instead, make whole device volume be decreased to traditional half;
3, the synthetic tower diameter is little, and compact construction is 3/4 of traditional synthetic tower volume;
4, in the synthetic tower packing layer is set, packing layer is provided with, in two-layer, make the mixed gas mixed distribution more even and increased residence time of mixed gas, make reaction more abundant.
5, tail gas cleaning, aftertreatment is easy;
6, make finished product purity height.
