Description

Technical Field

[0001] The invention relates to the technical field of ship exhaust gas treatment, and in particular to a liquid spraying device used on a ship exhaust gas scrubber. Background Art

[0002] The basic principle of supergravity engineering technology is to utilize the unique flow behavior of multiphase flow systems under supergravity conditions. The main way to obtain supergravity is to form a centrifugal force field by rotating the entire device or its components. The multiphase flow systems involved mainly include gas-solid systems and gas-liquid systems. The gas phase is introduced into the outer cavity of the rotor tangentially through the gas inlet pipe, and enters the metal wire mesh filler from the outer edge of the rotor under the action of gas pressure. The liquid is introduced into the inner cavity of the rotor through the liquid inlet pipe and sprinkled on the inner edge of the rotor through the nozzle. The liquid entering the rotor is affected by the filler inside the rotor, and the circumferential speed increases. The centrifugal force generated pushes it to the outer edge of the rotor. In this process, the liquid is dispersed and broken by the filler to form a huge and constantly renewed surface area, and the tortuous flow path intensifies the renewal of the liquid surface. In this way, excellent mass transfer and reaction conditions are formed inside the rotor. The liquid is thrown by the rotor to the outer shell and collected and then leaves through the liquid outlet pipe.

[0003] When the air washer is working, the rotor, driven by the rotating shaft, can rotate at a speed of several hundred or even thousands of revolutions. Due to the effect of gravity, the top part of the outer side of the filler cannot be well covered, resulting in a waste of efficiency. Summary of the invention

A through hole 1 is opened on the top of the rotor, and the two ends of the through hole 1 are respectively connected to the filler 3 and the liquid sealing structure, and a first spray hole 4 connected to the liquid sealing structure is opened on the side wall of the liquid inlet pipe 8, and the first spray hole 4 mainly functions The liquid is supplied to the liquid sealing structure, and a reaction liquid is provided as the liquid sealing liquid. When in use, liquid is sprayed into the liquid sealing structure through the first spray hole 4. When gas or solid particulate matter flows through the sealing area of ​​the liquid sealing structure, the density and viscosity of the liquid inside the liquid sealing structure will form a sealing layer. This liquid sealing layer can prevent gas leakage and can also absorb and block the movement of solid particulate matter, thereby playing an effective isolation and sealing role. In this process, a small part of the liquid used for sealing can enter the top area of ​​the filler 3 through the through hole 1, and the liquid is thrown off by the high-speed rotation of the filler 3, thereby realizing the effective utilization of the sealing liquid at the liquid seal under the premise of meeting the sealing requirements.
