摘要： To provide a mixing nozzle capable of efficiently mixing gas and solution.
The mixing nozzle 40 has a throat section 41, a diffuser section 42, a gas nozzle section 43, a first liquid suction port 44, a liquid nozzle section 45, a second liquid suction port 46, a baffle plate 47, and a jetting port 48. The first liquid suction port 44 liquidly absorbs the solution in the water storage pool from a side of the gas nozzle section 43 toward the gas nozzle tip 43a. The liquid nozzle section 45 extends to the downstream side of the gas nozzle section 43 with intervening the first liquid suction port 44. The second liquid suction port 46 liquidly absorbs the solution in the water storage pool from a side of the liquid nozzle section 45 toward the liquid nozzle tip 45a. The baffle plate 47 is provided such that the mixed flow mixed in the diffuser section 42 collides in front of a downstream end of the diffuser section 42, and divides and reverses the mixed flow such that high-speed reversed flow of the mixed flow is formed and the gas and the solution are mixed by centrifugal force.

摘要： Provided are a filtration material (1) for filtered venting and a filtered venting device (50) that are more effective in adsorbing radioactive iodine than in the conventional art and are useful for addressing severe accidents. The filtration material (1) for filtered venting comprises granulated zeolite L, wherein at least a portion of the ion exchange sites of the zeolite L are substituted with silver. Of the ion exchange sites, a constitution ratio (a/b) of ion exchange sites (a) substituted with silver to ion exchange sites (b) not substituted with silver is 25/75-55/45. The zeolite L has a silver content of 7-12 wt% on a dry weight basis.
