2O often claims on the engineering that oxidation air is an oxidation wind.The tradition desulfuration absorbing tower fills oxidation air and slurries part to mix in that mechanical stirring device need be set in stock tank when stock tank feeds oxidation air, with increase oxidation contact area, and quickening oxidation reaction speed.Existing oxidation air adding method is to send into stock tank inner ad-hoc location in absorption tower after utilizing oxidation fan that air is boosted, and this oxidation wind adding mode exists that energy consumption is high, noise is high and the reliability shortcoming that can't overcome such as low.
Summary of the invention
[0003] the purpose of this invention is to provide and a kind ofly can suck oxidation air fast and oxidation air is mixed with slurries fast mutually, require desulfuration absorbing tower lower, lower, that can save operating cost and reduce noise to spray suction apparatus with oxidation wind in the tower to the dependence of oxidation fan to the pressure of oxidation air.
Technical solution of the present invention is: it comprises slurries accelerating tube, slurries dilatation aspiration channel, aspiration channel sleeve pipe, oxidation air-slurries mixing tube and oxidation air suction line; The slurries accelerating tube is the conical pipe that internal diameter diminishes to outlet end from liquid feeding end gradually; Slurries dilatation aspiration channel is that tube wall is provided with a plurality of air admission holes, internal diameter becomes big conical pipe from liquid feeding end to outlet end gradually; The aspiration channel sleeve pipe is an internal diameter closing in pipe in two ends small in the end and big in the middle; Oxidation air-slurries mixing tube is a straight tube; The aspiration channel casing pipe sleeve is outside at slurries dilatation aspiration channel, the outlet end of slurries accelerating tube axially is connected with an end of slurries dilatation aspiration channel liquid feeding end and aspiration channel sleeve pipe; Be connected between slurries accelerating tube and the slurries dilatation aspiration channel; The other end of aspiration channel sleeve pipe is connected with the liquid feeding end of oxidation air-slurries mixing tube; Have annular oxidation wind between aspiration channel sleeve pipe and the slurries dilatation aspiration channel and suck the gap, have annular air-breathing gap between the inwall of the unsettled position that in oxidation wind sleeve pipe and with aspiration channel sleeve pipe and oxidation air-slurries mixing tube, is connected of the outlet end of slurries dilatation aspiration channel, an end of oxidation airduct laterally is connected with oxidation wind sleeve pipe, the other end extend to desulfuration absorbing tower outward and low-pressure oxidized blower fan or atmosphere be connected to slurries oxidation air be provided.
Technique effect of the present invention is: it can suck oxidation air fast and oxidation air is fully mixed with treating the oxidation slurries, and is lower to the pressure requirement of oxidation wind, lower to the dependence of oxidation fan, can reduce investment outlay and operating cost, reduces to move noise.The slurries of collecting with desulfuration absorbing tower high potential energy slurries gathering-device when this device uses on desulfuration absorbing tower are power; In course of injection, fully mix with the oxidation air suction and with treating the oxidation slurries; Accomplish major part and treat the oxidation of oxidation slurries; All the other oxidation airs flow back to the middle and lower part, absorption tower in company with slurry stream, bring oxidation wind into the absorption tower middle and lower part, continue to accomplish the oxidation of slurries.
This device has following function:
1, this device can make the high potential energy slurries in the decline process, oxidation air sucked and fully mix with treating the oxidation slurries, accomplishes most of oxidizing process;
2, the oxidation air that the jetting slurry flow that is lowered by sucks is injected into the inner slowly rising in the slurries pond behind the middle and lower part, slurries pond, absorption tower, further accomplishes oxidation;
4, the slurry stream that descends is sprayed and is sucked oxidation air, realizes replacing oxidation fan or reduces the effect that oxidation fan is exerted oneself, and realizes the absorption tower energy-saving run;
5, can realize that oxidation wind " the autonomous suction " perhaps cooperates the low-head oxidation fan to use; The method of operation of oxidation wind " the autonomous suction " does not need oxidation fan; The pressure head of low-head oxidation fan is the 3-15% of conventional oxidation blower fan (roots blower or centrifugal high pressure fan etc.) pressure head; Flow is lower than the 10-25% of conventional oxidation blower fan, and the method for operation is flexible;
6, desulphurization system has been cancelled traditional oxidation fan (roots blower or centrifugal high pressure fan), greatly reduces the operation noise.
