Immersion reactor
View Patent ↗The invention relates to an apparatus ( 1 ) for feeding chlorine dioxide to water, comprising a first feed pipe ( 5 a ) for feeding in a first reaction component, comprising a second feed pipe ( 5 b ) for feeding in a second reaction component, comprising a mixing tube ( 2 ) for mixing and reacting the two reaction components to chlorine dioxide, at one end of which the two feed pipes ( 5 a , 5 b ) join and at the other end of which is arranged a suction chamber ( 4 ) into which feed water to be enriched with chlorine dioxide can be sprayed by means of a nozzle ( 12 ), and comprising an exit water pipe ( 13 ) leading downstream from the suction chamber ( 4 ). This object is further to develop such an apparatus so that it is simple and has a robust design and permits different chlorine dioxide syntheses based on two reaction components to be carried out without danger. This object is achieved if the mixing tube ( 2 ) is provided with an ancillary entry opening ( 10 ) for the entry of ancillary water to be enriched with chlorine dioxide and free of reaction components.
1. A system for feeding chlorine dioxide to water, comprising:
a water bath; and
a device submersed in the water bath for generating and/or supplying chlorine dioxide to the water bath;
wherein the device comprises in vertical order from lowermost to uppermost:
a base plate having a first feed pipe and
a second feed pipe;
a mixing tube comprising a lower region wherein the first and second feed pipes enter at a joining point and an upper region comprising an ancillary entry open to the water bath; and
a suction chamber at an upper end of the mixing tube and open to the mixing tube; and
a clamping set suitable for exerting an axial force on the mixing tube between the base plate and the suction chamber;
wherein the suction chamber comprises:
a water feed nozzle for spraying water into an upstream portion of the suction chamber, and
an exit water pipe in a downstream portion of the suction chamber, and
wherein the base plate closes the lower region of the mixing tube.
2. The system according to claim 1 ,
wherein the ancillary entry opening is located downstream of the joining point such that reaction of components entering at the joining point is complete at the ancillary opening.
3. The system according to claim 1 , wherein the water feed nozzle and the exit water pipe are coaxial with one another in a region of the suction chamber.
4. The system according to claim 3 , wherein the mixing tube extends radially relative to the axis of the water feed nozzle and the exit water pipe, in the region of the suction chamber.
5. The system according to claim 3 , wherein the mixing tube extends coaxially with the axis of the water feed nozzle and the exit water pipe, in the region of the suction chamber.
6. The system of claim 1 , wherein a slenderness ratio of the mixing tube, as measured from the joining point furthest downstream to the ancillary entry opening is between five and eight.
7. The system of claim 1 ,
wherein the mixing tube is immersed in the water bath such that ancillary water from the water bath enters the mixing tube through the ancillary entry opening.
8. The system according to claim 7 , wherein the exit water pipe opens into the water bath.
9. The apparatus according to claim 1 , further comprising:
a feed water pipe leading from the water bath to the nozzle.
10. The system of claim 7 , wherein the water bath is a basin of a cooling tower.
11. A system for adding chlorine gas to water, comprising:
a water bath; and
a device submersed in the water bath for supplying chlorine to the water bath;
wherein the device comprises in vertical order from lowermost to uppermost:
a base plate having a feed pipe suitable for feeding chlorine gas,
a mixing tube suitable for mixing the chlorine gas with water, wherein the feed pipe enters the mixing tube at a first end of the mixing tube, and an ancillary entry open to the water bath at a second end of the mixing tube,
a suction chamber at a second end of the mixing tube and open to the mixing tube,
a clamping set suitable for exerting an axial force on the mixing tube between the base plate and the suction chamber;
wherein the suction chamber comprises:
a water feed nozzle for spraying water into an upstream portion of the suction chamber, and
an exit water pipe in a downstream portion of the suction chamber, and
wherein the base plate closes the lower region of the mixing tube.
12. The system according to claim 11 , further comprising:
a second feed pipe for feeding water into the mixing tube, the second feed pipe joining at the first end of the mixing tube.
13. The system according to claim 11 , wherein the exit water pipe opens into the water bath.
14. The system according to claim 11 , further comprising:
a feed water pipe leading from the water bath to the nozzle.
15. The system of claim 11 , wherein the water bath is a basin of a cooling tower.
