Abstract
The utility model discloses a gas stripping device for recycling condensate of a chlorine dioxide generator. The gas stripping device comprises a packed tower, a chlorine dioxide gas outlet formed on the top of the packed tower, a chlorine dioxide condenser condensate inlet formed on the side wall of the top of the packed tower, and a gas stripping air inlet and a post-gas stripping liquid outlet which are formed at the bottom of the tower, and also comprises a tower top liquid distributor fixed on the top of the packed tower and connected with the condensate inlet, and a liquid redistributor fixed on the middle part of the packed tower and diving the packed tower into an upper packed tower and a lower packed tower. The gas stripping device comprehensively recycles the chlorine dioxide gas through the upper and lower packed towers, ensures the recycle of the chlorine dioxide gas to the greatest extent, and ensures full recycle of the chlorine dioxide in a double recycle mode of the tower top liquid distributor and the liquid redistributor.
Description
Technical field
The utility model relate to use in the paper-making industry production process the reclaimer technical field, relate in particular to a kind of air-lift device that reclaims the chlorine dioxide generator condensate liquid.
Background technology
At present synthesis is produced in the chlorine dioxide process, and chlorine dioxide condenser condenses liquid located to be equipped with two kinds of disposal options.The one, condensate liquid is carried without gas and is directly got into the chlorine dioxide absorption tower; The characteristics of this processing mode are that chlorine dioxide has reclaimed; But the contained sodium salt of condensate liquid removes to starch bleaching process with chlorine dioxide and enters into waste water; Not only contaminated environment but also loss system sodium salt, operation a period of time, system need replenish medicines such as sodium chloride, sodium dichromate; The 2nd, condensate liquid extracts the mode of sodium salt again after gas is put forward; But present stripping tower is owing to the reason of structure and system's design limitations; Gas device reclaims the rate of recovery of chlorine dioxide and has only 50%; Far away from the organic efficiency on absorption tower, though condensate liquid can be recovered sodium salt after gas is carried, the rate of recovery of chlorine dioxide but can not be satisfactory.
Summary of the invention
Can not absorb for sodium salt in order to remedy in the above-mentioned chlorine dioxide removal process chlorine dioxide absorption tower; And that condensate liquid is put forward mode through gas is all unsatisfactory for the recovery of sodium salt and chlorine dioxide; Inefficient defective; The utility model proposes a kind of air-lift device of recovery chlorine dioxide generator condensate liquid of comprehensive high-efficiency, and its technical scheme is a kind of air-lift device of recovery chlorine dioxide generator condensate liquid of comprehensive high-efficiency; Comprise packed tower; Open the chlorine dioxide outlet on the packed tower top, the gentle back liquid outlet of carrying of gas exhaust gas import at the bottom of tower is opened in the chlorine dioxide condenser condenses liquid import of opening the sidewall on the packed tower top; Also comprise being fixed on the overhead liquid distributor that the packed tower top is connected with the condensate liquid import, be fixed on the liquid re-distributor that is divided into packed tower and following packed tower in the middle part of the packed tower and with packed tower.Adopt this programme packed tower chlorine dioxide comprehensively to be reclaimed through upper and lower two packed towers; Farthest guaranteed the recovery of chlorine dioxide; Adopt two ways of recycling of overhead liquid distributor and liquid re-distributor, guaranteed the abundant recovery of chlorine dioxide.
Saidly go up between packed tower and the liquid re-distributor and liquid is connected through flange between distributor and following packed tower.
Said overhead liquid distributor comprises the shower of being responsible for and being communicated with the person in charge, also has a plurality of spray looped pipelines on the shower.Adopt this mode, guaranteed the abundant spray of condensate liquid, make the recovery of condensate liquid more abundant.
Said liquid re-distributor is the porous support holder structure, and the condensate liquid that is by convection into liquid re-distributor is done spray once more.
The utility model adopts two sections packed towers and two liquid re-distributors to cooperatively interact, and chlorine dioxide is reclaimed fully, has improved the organic efficiency of chlorine dioxide, saves resource, the protection environment.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 be the utility model the overhead liquid distributor look up structural representation;
Among the figure, 1, packed tower; 2, chlorine dioxide outlet; 3, condensate liquid import; 4, gas exhaust gas import; 5, gas is carried the back liquid outlet; 6, overhead liquid distributor; 7, go up packed tower; 8, following packed tower; 9, liquid re-distributor; 10, be responsible for; 11, shower; 12, flange; 13, the spray looped pipeline.
The specific embodiment
With reference to the accompanying drawings the utility model is further specified.
With reference to Fig. 1; A kind of embodiment of the utility model; A kind of air-lift device of recovery chlorine dioxide generator condensate liquid of comprehensive high-efficiency comprises packed tower 1, opens the chlorine dioxide outlet 2 on the packed tower top; Open the chlorine dioxide condenser condenses liquid import 3 of sidewall on the packed tower top; Open the gas exhaust gas import 4 gentle back liquid outlets 5 of carrying at the bottom of tower, also comprise being fixed on the overhead liquid distributor 6 that the packed tower top is connected with the condensate liquid import, be fixed on the liquid re-distributor 9 that is divided into packed tower 7 and following packed tower 8 in the middle part of the packed tower and with packed tower.
Saidly go up between packed tower and the liquid re-distributor and liquid is connected through flange 12 between distributor and following packed tower.
With reference to Fig. 2, said overhead liquid distributor comprises the person in charge 10 and is communicated with the shower of being responsible for 11, also has a plurality of spray looped pipelines 13 on the shower, has guaranteed the abundant spray of condensate liquid, makes the recovery of condensate liquid more abundant.
Said liquid re-distributor is the porous support holder structure, and the condensate liquid that is by convection into liquid re-distributor is done spray once more.
In the utility model work; Condensate liquid flows into the overhead liquid distributor from the condensate liquid inlet; By the overhead liquid distributor with liquid spraying in last packed tower, when condensate liquid flowed into packed tower, gas exhaust gas also got in the packed tower from the import of gas exhaust gas; Gas exhaust gas gets into upward packed tower through the hole of liquid re-distributor; The condensate liquid that gas exhaust gas and spray are opened in last packed tower begins reaction, and the chlorine dioxide in the condensate liquid is tentatively extracted recovery, and the chlorine dioxide that from condensate liquid, extracts is recycled by the gas vent on packed tower top.
The condensate liquid at overhead liquid distributor spray place is after reclaiming through the preliminary extraction of chlorine dioxide; Flow on the liquid re-distributor; Hole by liquid re-distributor gets into down packed tower once more; Following packed tower inner condensat liquid once more with gas exhaust solid/liquid/gas reactions, the chlorine dioxide that produces through the reaction back gets into upward through the hole of liquid re-distributor that packed tower also finally is recovered by gas vent.
Carry the back liquid outlet by the gas at the bottom of the tower at last through the condensate liquid after the upper and lower packed tower recovery and flow out packed tower, get in the operation of next extraction sodium salt.
The above; Preferable case study on implementation for the utility model; Be not that the utility model is done any restriction; Everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of the utility model technical scheme according to the utility model technical spirit.
