spray pipe device

Abstract

A spray nozzle device is disclosed for use in a high-gravity rotating bed. The high-gravity rotating bed has multiple packing bodies. The spray nozzle device comprises multiple coaxially arranged spray nozzles of different lengths. Each spray nozzle has at least one spray hole. The spray hole of each spray nozzle is exposed outside adjacent spray nozzles and is used to spray a different liquid. The spray holes of the spray nozzles are used to spray different liquids onto the packing bodies respectively, thereby removing different types of contaminants from the gas passing through the high-gravity rotating bed or improving the removal efficiency of the same contaminant. Additionally, the spray holes of the spray nozzles can be used to sequentially penetrate the corresponding packing bodies in series to contact the gas, thereby improving the removal efficiency of the contaminant in the liquid.

Claims

1. A spray nozzle device suitable for a high-gravity rotating bed, the high-gravity rotating bed being used to rotate about an axis to generate a high-gravity field, and having a plurality of fillers arranged in a direction parallel to the axis, the fillers being hollow cylinders and their inner surfaces collectively defining a spray space, the spray nozzle device comprising: Multiple spray pipes, each with a different inner diameter, outer diameter, and length, are coaxially arranged and pass through a spray space. Each spray pipe has at least one set of spray holes, and each set of spray holes has at least one spray hole formed on the outer circumferential surface of the spray pipe. The spray holes of each set of spray holes are exposed outside the adjacent spray pipes and are used to spray a different liquid. The spray holes of the spray pipes are respectively aligned with at least a few of the fillers at different positions and are used to spray different liquids onto the aligned fillers, so that each liquid penetrates the corresponding filler radially outward.

2. The spray nozzle device as claimed in claim 1, wherein, The axis of these spray nozzles is aligned with this axis.

3. The spray nozzle device as claimed in claim 1, wherein, Two adjacent spray pipes are defined as the first spray pipe and the second spray pipe, respectively. The inner diameter of the first spray pipe is larger than the outer diameter of the second spray pipe, and the second spray pipe is coaxially inserted into the first spray pipe.

4. The spray nozzle device as claimed in claim 3, wherein, The opening of the spray space is located at one end of the axis; each spray tube enters the spray space from the opening and extends in a direction parallel to the axis. The second spray tube includes an inner tube portion coaxially inserted into the first spray tube and a protruding tube portion that communicates with the inner tube portion and protrudes from the end of the first spray tube away from the opening of the spray space. The spray hole of the second spray tube is formed on the outer peripheral surface of the protruding tube portion.

5. The spray nozzle device as claimed in claim 4, wherein, The cross-sections of the inner tube portions of the first and second spray pipes are concentric circles.

6. The spray nozzle device as claimed in claim 1, wherein, The number of spray pipes is three. The three spray pipes are arranged coaxially and are defined as the first spray pipe, the second spray pipe and the third spray pipe in sequence from the outside to the inside along the radial direction of the three spray pipes.

7. The spray nozzle device as claimed in claim 6, wherein, The opening of the spray space is located at one end of the axis; each spray tube enters the spray space from the opening and extends in a direction parallel to the axis. The second spray tube includes an inner tube portion coaxially inserted into the first spray tube and a protruding tube portion that communicates with the inner tube portion and protrudes from the end of the first spray tube away from the opening of the spray space. The spray hole of the second spray tube is formed on the outer peripheral surface of the protruding tube portion.

8. The spray nozzle device as claimed in claim 7, wherein, The third spray pipe includes an inner tube portion coaxially inserted into the second spray pipe, and a protruding tube portion communicating with the inner tube portion and protruding from the end of the second spray pipe away from the opening of the spray space. The spray hole of the third spray pipe is formed on the outer peripheral surface of the protruding tube portion.

9. The spray nozzle device as claimed in claim 6, wherein, The position of the spray hole of the second spray pipe in a direction parallel to the axis is between the spray hole of the first spray pipe and the spray hole of the third spray pipe.

10. The spray nozzle device as claimed in claim 1, wherein, Each of the spray pipes has a plurality of spray hole groups, which are arranged in a direction parallel to the axis and exposed outside the adjacent spray pipes.
