Description of drawings
Accompanying drawing is a specific embodiment synoptic diagram of the present utility model.
Embodiment
Ask for an interview accompanying drawing, as a preferred embodiment, provided three groups of identical water absorbing mechanisms 1 consistent with action principle of structure, the applicant is being that one group of water absorbing mechanism 1 on the left side is that example is described in detail by first group shown in the drawings at present.Comprise the absorption tower 11, storage tank 12 and the recycle pump 13 that are used to absorb waste gas, absorption tower 11 can be bearing on the terrace 3 by the support (not shown), the position of storage tank 12 should remain below the degree of the height on absorption tower 11, that is to say that storage tank 12 is positioned at the below on absorption tower 11, the top of storage tank 12 is equipped with blow-off valve 123.It is XDT101 type polypropylene tail gas absorber that the model by the production and sales of Taicang, the Jiangsu Province, China rotten sterilization of new joint defence Engineering Co., Ltd is adopted on preferred but not absorption tower 11 that be limited to.The gas at 11 tops, absorption tower is introduced and is connected waste gas introduction pipeline 1121 on the interface 112, by this waste gas introduction pipeline 1121 hydrogenchloride and the sulfurous gas mix waste gas that produces in for example chlorination reaction process in the Thioctic Acid production process is incorporated in the absorption tower 11.The gas of 11 bottoms, absorption tower is drawn interface 111 and is introduced interface 121 connections by first pipeline 1211 and the gas at storage tank 12 tops that fill water, after hydrogenchloride and sulfurous gas mix waste gas are incorporated in the storage tank 12 by first pipeline 1211, sulfurous gas is water insoluble because hydrogen chloride gas is soluble in water, therefore hydrogen chloride gas just separates with sulfur dioxide gas in storage tank 12, add the effect of recycle pump 13, hydrogen chloride gas can be dissolved in the storage tank 12 ideally.See by accompanying drawing, a client link of the fluid inlet of recycle pump 13 and the 3rd pipeline 131, and the other end of the 3rd pipeline 131 and storage tank 12 connect; One client link of the liquid outlet of recycle pump 13 and the 4th pipeline 132, and the top on the other end of the 4th pipeline 132 and absorption tower 11 connects.
Because the water absorbing mechanism 1 that present embodiment is recommended has three groups, therefore, the gas at the top of the storage tank 12 of first group of water absorbing mechanism 1 by being connected second pipeline 1221 on the gas outlet 122 and second group of absorption tower 11 that is the one group of water absorbing mechanism 1 in centre shown in the drawings is introduced interface 112 and is connect.In like manner, the storage tank 12 of second group of water absorbing mechanism 1 is that the gas at top on absorption tower 11 of one group of water absorbing mechanism 1 on illustrated the right is introduced interface 112 and connect by second pipeline 1221 and the 3rd group, thereby constituting three grades of circulations absorbs, effectively hydrogenchloride is separated with the sulfurous gas mix waste gas, make hydrogen chloride gas be tending towards absorbing totally.When the concentration of the hydrogen chloride solution in the storage tank 12 when sampling analysis reaches blowing concentration, then emit reuse.Here alleged blowing concentration determines as required that usually the blowing concentration that the applicant selects is 〉=30%, and promptly the content of hydrogenchloride in water is 〉=30%.Before blowing, close first valve 4 on the 4th pipeline 132 of the recycle pump 13 that is located at second group of water absorbing mechanism 1 and close second valve 6 on the 4th pipeline 132 of the recycle pump 13 that is located at the 3rd group of water absorbing mechanism 1, open the 3rd valve 51 and the 4th valve of opening on the 7th pipeline 7 71 on the 6th pipeline 5, under the work of the recycle pump separately 13 of three groups of water absorbing mechanisms 1, making hydrogen chloride solution in the storage tank 12 of second group and the 3rd group water absorbing mechanism 1 be transferred to first group is in the storage tank 12 on the attached illustrated left side, specifically to be by the 6th, the 7th pipeline 5,7 take on.Owing to there are three storage tanks 12, therefore, when a storage tank 12 is not the 12 benefit entry of the storage tank in the right shown in the drawings to the end, the blow-off valve on each storage tank 12 123 should be opened, after moisturizing finishes, promptly close blow-off valve 123.
Because hydrogen chloride gas is absorbed by water absorbing mechanism 1, therefore by the end not second pipeline 1221 of one group of water absorbing mechanism 1 gas that is incorporated into reaction mechanism 2 be sulfur dioxide gas, sulfur dioxide gas enters (suction) reactor 21 under the effect of vacuum pump 22, be 32% sodium hydroxide solution as long as add concentration in the reactor 21 that has stirring this moment, and 50 ℃ of control reaction temperature, when the pH of the reaction solution in the reactor 21 value reaches 5.6, reaction solution is switched to continuation absorption sulfur dioxide gas in another reactor (not shown), specifically be to add 32% sodium hydroxide solution again, when the pH of reaction solution value reaches 9.5～10, then obtain sodium sulfite solution, cool off with icy salt solution, when temperature reaches 30 ℃, can separate out the xln of seven aqueous sodium persulfates in a large number, when temperature is reduced to 20 ℃, the material in the reactor be emitted, separate through whizzer, obtain product seven water S-WATs.The vacuum tightness of aforesaid vacuum pump 22 is-0.09MPa.Vacuum pump 22 is connect by the 5th pipeline 221 and reactor 21.
