The utility model discloses a realize through following technical scheme.
The utility model discloses a coking gas washing tower whirl spray set, including scrubbing tower, filler, contain impurity gas inlet pipe, impurity gas shower nozzle, purification gas exit tube, washing water purification pipe, water purification shower nozzle, wet return, circulating pump, circulating water pond. The middle part of the washing tower is provided with a filler, an impurity-containing gas inlet pipe and an impurity gas spray head are arranged below the filler, and the top of the washing tower is provided with a purified gas outlet pipe. And a washing water purifying pipe and a water purifying spray head are arranged above the filler, and a water return pipe is arranged at the bottom of the washing tower. The water return pipe is communicated with an external circulating water tank. The circulating pump pumps the circulating water in the circulating water tank into the washing water pipe through the filter to form washing purified water circulation. The water purifying nozzle is characterized in that a spiral shaft sheet is arranged in the outer wall of the washing water purifying pipe and fixed at the end of the washing water purifying pipe through a connecting piece, and the gap between the outer edge of the spiral shaft sheet and the inner wall of the pipe is 8-12mm.
The spiral shaft piece is divided into a left-handed spray head and a right-handed spray head in different installation directions in the pipe.
The end of the water purifying spray head is downwards arranged above the filler in the washing tower. The water purifying nozzles are arranged in the washing tower in a triangular layout or a cross layout, the triangular layout is a left-handed nozzle close to the near end of the washing water purifying pipe, and the other two nozzles are right-handed nozzles. The cross layout is that two of diameter connecting lines are left-handed spray heads, and the other two are right-handed spray heads.
The beneficial effects of the utility model are that: (1) The utility model discloses a washing water purification when the water purification shower nozzle, liquid phase becomes high-speed rotatory flow by the runoff in the water purification shower nozzle, rotatory liquid drop is loudspeaker form downwardly spraying behind the liquid phase blowout water purification shower nozzle, meet with the impurity-containing air current that rises from packing until, it descends in packing to receive the gravity again after the resistance is balanced, at this in-process, rotatory liquid drop and the gaseous abundant contact that rises form the gas phase disturbance, make the gaseous sanitization that contains the impurity, full play the function of scrubbing tower. (2) The utility model discloses a water purification shower nozzle is with triangle-shaped or cross overall arrangement in the scrubbing tower, including the cooperation installation of levogyration and dextrorotation, makes the cross section of packing be sprayed the water purification and cover completely, makes to contain impurity gas and obtains wasing completely, and reasonable shower nozzle distributes, and water distribution is even, and system resistance is little, and the gas water ratio is more traditional device increased more than 20%. (3) The utility model discloses a whirl spray set's rotatory liquid drop direct injection has prevented the scale deposit of packing and blocking phenomenon's emergence on packing. (4) The utility model discloses a flight is formed by the ironcasting processing, and is stand wear and tear very much, consequently, this spray set operation is stable, and long-lived has saved maintenance cost and running cost.
