A Way to Decrease the Negative Impact of Aquaculture on other Marine Inhabitants

Spat collectors deployed at sea, in addition to the target species, attract also many larvae of accompanying species, which die after transplanting the cultivated one into cages. However, these juveniles often have a higher value than the cultivated species, and their mortality is caused by smaller sizes. These are： red king crab, Japanese sea cucumber, sea urchins, Japanese cucumaria and several species of ascidians and sponges. However, the use of a realized niche, rather than a fundamental one, in selecting the area and depth to install collectors, and also improvement of their design, make it possible to cultivate a target species without reseeding to other constructions. This not only facilitates the cultivation process, but also increases the survival rate of the cultivated and accompanying species, since at the bottom, they reach either marketable or viable size in comfortable conditions.

一种同轴式圆笼除尘器的设计与应用

探讨一种同轴式圆笼除尘器的设计和应用效果。分析了格栅反吸式圆笼除尘器存在的不足之处,对现行结构进行了改进,将一级除尘和二级除尘传动的动力源合并由同一个电机输出,粉尘也由同一个吸尘风机捕集后输送到压紧器中。认为该同轴式圆笼除尘器在结构上更简单紧凑,易于维护维修,整体空间利用率更高,占地更小,能耗降低,投资运行成本减小。

电袋复合除尘器喷吹管及袋笼的改进

电袋复合除尘器因其具有处理烟气量大、除尘效率高等优点,在工业烟尘治理领域中具有很好的应用前景。但在实际应用过程中仍存在一些问题,如喷吹管拆装困难和袋笼易发生漏装且运输不便。针对该问题,本文结合高压锅和消防栓的连接密封原理设计了一种快速拆装的喷吹管,与一种可折叠、伸缩的袋笼。

除尘器有限空间的粉尘燃爆风险与控制措施

文章梳理并分析了可燃性粉尘的燃爆风险,简述了袋式除尘器的防爆设计规范,详述了袋式除尘器核心部件——滤袋和袋笼的防静电机理与处理措施,从而达到防范粉尘燃爆事故的目的。
