在喷射式净气机的头部,注入并细密地分散通过特殊推进喷嘴的洗涤液,以形成最大的气/液交换表面,并以相对较高的速度落到气流上。由于能量输入高,喷射式净气机自身即可吸入和排出气体或废气。这种注射机效果可在不造成气体压力损失的情况下净化废气。因此,一般而言,无需使用机械通风设备来排出和输送气体。
在修改后的包含骤冷功能的设计中,一个过程即可冷却和净化高达 1,300 °C 的气体。
同时,骤冷效果可确保冷却气体或蒸汽。因此,通过将水蒸发到气流中,气流会冷却到合适的冷却极限温度。通过热传导,可以冷却蒸汽并进行冷凝。
在通过喷射管道的过程中,吸收功能会将污染物成分溶解在液体中。如果采用化学吸收方法,将以化学方式吸附污染物成分。
这样,每个洗涤阶段的分离效率可高达 98%。
得益于所谓的惯性分离效果,固体微粒或液滴会在动力喷嘴区域与快速喷射的液滴发生碰撞而达到分离的效果。这样,差不多可以彻底提取出直径 ≥ 5 微米的微粒。
在喷射式净气机的末端,必须通过一个下游离心分离机再次分离气体与液体。
At the head of the jet scrubber, a scrubbing fluid via special propelling nozzles is injected and finely dispersed to produce a maximum gas/liquid exchange surface. It drops with high relative speed to the gas flow.
Due to the high energy input, the jet scrubber has the capacity to take and deliver gases or fumes by itself. This injector effect allows cleaning of the exhaust gases without generating pressure loss on the gas side. Therefore, as a rule of thumb, there is no requirement for a mechanical ventilator to draw off and convey the gas.
Given the modified design, including a quench, gases at up to 1,300 °C can be cooled and scrubbed in one process.
The quench effect ensures the cooling down of gases or vapors, causing the gas stream to cool down to its respective cooling limit temperature by evaporation of water into the gas stream. Vapors can be cooled down and condensed by heat conduction.
Along the way through the jet tube, the absorption of the pollutant component dissolves in the liquid. In the case of chemical absorption, the pollutant component is bound chemically.
Benefiting from the so-called “inertial separation effect”, solid particles or drops are separated in the motive nozzles by colliding with fast-flying droplets of the liquid.
Gas and liquid must be separated again at the end of the jet scrubber tube by a downstream centrifugal separator.
垂直立管、文丘里喉管、置换器(文丘里锥形管)和喷雾喷嘴同一中心排列在文丘里喉管上方的管道上。
为了防止由于存储容器或计量设备发生泄露而逸出的氯气发生事故,GEA 开发了氯气应急装置,它根据喷射式净气机的原理运行。
在 1950 年开发出了可调环缝净气机,旨在提供灵活的装置,能够处理歧管工业排气问题,如今已经成为出色的高效率净气机。考虑到固体和液体灰尘颗粒的粒径以及气体混合物中气体成分的浓度,实际应用中在分离上没有对环缝净气机设定最小限制。
Next generation scrubber for more than the non-ferrous metallurgical industry. Used for dust and particulate removal in saturated waste gases, Linear Flow Scrubbers offer increased energy savings and efficiency thanks to their high adaptability, adjustability capacity to steadily scrub at fluctuating gas flow rates.
