Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be further described by the following detailed description with reference to the accompanying drawings.
Referring to fig. 1 to 3, a spray device in a rotary arrangement mode comprises a pipeline 1, wherein a plurality of nozzles 2 are arranged in the pipeline 1, the central line 11 of the pipeline 1 is different from the central line 21 of each nozzle 2, the opening of each nozzle 2 faces to the gas flowing direction in the pipeline 1, an included angle formed by the central line 21 of the nozzle 2 and the corresponding radial section is more than 0 degrees and less than or equal to 90 degrees, and the nozzles 2 arranged on the same radial section of the pipeline 1 are arranged in a clockwise or anticlockwise rotation mode. The central line 11 of the pipeline 1 and the central line 21 of each nozzle 2 are different in surface, so that the slurry can be mixed with the flue gas at a certain angle, and the slurry is not crossed, so that the slurry and the flue gas can be fully contacted in the flue gas flowing direction B, the harmful gas in the flue gas can be fully absorbed, and the spraying efficiency of the spraying device is improved; because the opening of each nozzle 2 faces to the gas flowing direction in the pipeline 1, the slurry has a pushing force in the flue gas flowing direction B to push the flue gas to flow, so that the mixing of the slurry and the gas is promoted, and the spraying efficiency of the spraying device is improved; in addition, through the combination of the arrangement of the nozzles 2 on the same radial section of the pipeline 1 in a clockwise or anticlockwise rotation direction, the spiral movement A of the slurry, which is covered in Zhou Xiangquan directions and is formed by combining the rotation of the slurry in the circumferential direction clockwise or anticlockwise direction and the linear movement of the slurry in the flow direction B of the flue gas, is realized, the full contact of the slurry and the flue gas is ensured, and the spraying efficiency of the spraying device is improved.
The distance between the openings of the nozzles 2 on the same radial section and the central line 11 of the pipeline 1 is the same, and each nozzle 2 on each radial section is uniformly arranged along the circumferential direction, so that the sprayed slurry can do circumferential motion on the circumferential direction of each radial section, uniform circumferential stress of the flue gas can be ensured, and the harmful substances in each part of the flue gas can be uniformly absorbed. At least 2 nozzles 2 per radial cross section ensures a more uniform mixing.
The distance from the opening of the nozzle 2 to the central line 11 of the duct 1 is gradually reduced along the direction of gas flow, so that the arrangement is provided because the harmful substances contained in the flue gas along the traveling direction thereof are gradually reduced in the process of transferring, and the gas flow of the flue gas is gradually reduced and gathered near the central line 11 of the duct 1 along with the movement of the traveling direction, so that the spraying treatment of absorbing harmful substances can be carried out on the flue gas with smaller gas flow in a targeted manner.
The included angle formed by the central line 21 of the nozzle 2 on the radial section and the radial section is more than 0 degrees and less than 90 degrees, so that the nozzle 2 faces to the smoke flow direction B and is not parallel to the smoke flow direction B, and the mixing of slurry and smoke can be promoted. The central line 21 of the nozzle 2 on the same radial section and the radial section form the same included angle, so that the flue gas is impacted uniformly by the slurry in the circumferential direction, and the mixing of the slurry and the flue gas is promoted. As the displacement of the flue gas in the advancing process is gradually reduced, along the gas flowing direction, the included angle between each radial section and the central line 21 on which the nozzle 2 is arranged is gradually increased, so that the slurry can ensure that the impact component of the flue gas on the flowing direction B is larger and larger, and the movement of the flue gas along the flowing direction B is promoted. Each nozzle 2 rotates along the corresponding central line 21, the movement of the slurry is complex, the contact between the slurry and the smoke is enhanced, and the absorption of harmful substances in the smoke is promoted. The shape of each nozzle 2 is a truncated cone with the sectional area gradually increased from back to front, so that the slurry can be sprayed out at a wide angle, and the contact area between the slurry and the flue gas is increased.
The radial cross section of the pipeline 1 is circular, in addition, the radial cross section of the pipeline 1 can also be rectangular, elliptical and the like, and the circular arrangement has the advantages that as the spraying device is uniformly arranged in the circumferential direction, the pipeline 1 with the circular radial cross section can be well matched with the arrangement, the utilization rate of the inner space of the pipeline 1 is improved, and therefore the spraying effect can be enhanced.
Note that the basic principles and main features of the present invention and advantages of the present invention are shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the foregoing embodiments, but rather, the foregoing embodiments and description illustrate the principles of the invention, and that various changes and modifications may be effected therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
