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 is a radioactive iodine adsorbent capable of adsorbing radioactive iodine more effectively than in the conventional art, and removing hydrogen, which is a factor in nuclear reactor accidents. A granulated radioactive iodine adsorbent of zeolite X, wherein ion exchange sites of the zeolite X are substituted with silver so that a size of minute pores of the zeolite X is suited to a size of a hydrogen molecule, and the radioactive iodine adsorbent has a silver content of 36 wt% or more when dried, a particle size of 10 × 20 mesh, a hardness of 94% or more, and a water content of 12 wt% or less when dried at 150°C for 3 h and thereby reduced in weight.
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.
摘要:
A method and system for reclaiming aggregate from concrete waste material (B) includes crushing step and means (14,74) of compression-crushing lumps of concrete waste material into a crushed mixture, and sorting (22,82) the crushed mixture by size thereof, grinding step (24,26,84,86) and means of rotating the crushed mixture sorted to grind it with a grinding member (94) which rotates in an opposite direction to the rotating direction of the crushed mixture sorted, thereby peeling mortar from gravel, crushed stones and sand of the crushed mixture to obtain a mixture of gravel, crushed stones, sand, cement and mortar, and product separating step and means (46,110) of separating the mixture of gravel, crushed stones, sand, cement and mortar into gravel and crushed stones (J), sand (N), cement and mortar (M).
摘要:
Provided is a new heat source device that utilizes the catalytic reaction heat as a heat source for industries. The heat source device 100 utilizing the catalytic reaction heat of silver zeolite 1 includes an accommodation container 10 for accommodating the silver zeolite 1 while ensuring air permeability, wherein the accommodation container 10 is configured to be ventilated with a mixed gas G containing hydrogen, steam, and air. The mixed gas has a hydrogen concentration of 1 to 20% by volume, a steam concentration of 1 to 95% by volume, an air concentration of 1 to 95% by volume, and a temperature of 100°C or higher.
