过滤技术

在固/液分离方面 60 余年的经验

BHS 在滤饼过滤这一专业领域已有 60 多年的历史:早在 1953 年,就已经研发出了第一台加压转鼓过滤机。我们借助压力或真空过滤生产用于进行机械固液分离的过滤器和过滤系统。所有 BHS 过滤机的特点是,它们都能在滤饼比较薄的条件下工作。不言而喻,即使是特定规范和认证条例(例如:GMP、CIP、Atex 等)中的苛刻要求,我们的过滤解决方案也能满足。

我们广博的专业知识基于全球已实现的四位数范围内应用的宽泛领域。重点是化学和制药工业、食品和塑料工业、石油和天然气开采以及能源和原料生产领域的工艺过程。

为了分离固体颗粒,使用由织物或金属材料、亦或由复合材料制成的过滤介质,在过滤介质上形成滤饼。此外,常常还要进行一个洗涤过程,以改善滤饼的纯度或提高液相产品的产量。固液分离可以以批量或连续的生产方式进行。

在实践中,对每个具体应用场合都需要进行详细的分析,以确定最佳的工艺技术基础。在这里,在过滤技术领域六十多年的工作经验让我们非常受益,凭借相应的工艺经验我们还开发了宽泛的产品组合。因此,在每个单独项目中我们都会与客户共同阐明不同的工艺步骤,共同斟酌不同的工艺技术替代方法,以便在之后为各种特殊情况选择和实施最佳解决方案。通常,我们会在我们自己的过滤实验室中或者在客户处以中试规模进行初步试验,以达到最终确认:确定了合适的工艺流程后,接下来即可轻松将其从实验室扩大到生产规模。

我们十分乐意为您提供的各种试验用过滤机,以及我们在 Sonthofen 设有化学实验室的现代化技术实验中心,完善了我们为您的要求找出最佳解决方案的能力。

Continuous Pressure And Vacuum Filtration Technologies as Alternatives to Batch Filtration Operations

This paper discusses the selection of the filtration process systems: continuous pressure and/ vacuum filtration through a process of laboratory and pilot testing. These tests enable problem analysis, technology selection and scale up which help in optimum filter selection.

Combination filtration of pressure, vacuum and clarification technologies for optimum process solutions

Filtration experts, over the years, have discussed combination filtration and debated its definition. In the realm of cartridge filtration, simply defined, a combination filter is one that does at least one other processing job at the same time as filtering a suspension. For example, this could be carbon canister which removes both suspended and dissolved components. In water applications, a combination filter removes bacteria, sediment, chlorine taste and odor, and scale. In lubrication oil filtration, combination filtration refers to full-flow and by-pass flow filtration. Finally, for small scale process filtration, combination filtration is installing bag and cartridge filtration systems in series.

There is, however, a new definition of combination filtration that transcends the standard approach and will assist process engineers with trouble shooting and “idea-generation.” The approach relies upon the slurry analysis and testing to uncover the “process symptom” and then develop a process solution called “combination mechanical slurry conditioning and filtration.” This article discusses slurry testing and process analysis and then illustrates seven case history example installations showing “combination mechanical slurry conditioning and filtration” including data in Appendix A.
