A Development of Removal Equipment for Hazardous Gases in the Indoor Air by Diffusion Scrubber Method

各种危险的化学品集中在室内空气与工业化的快速增长中。例如， Formaldehyde （HCHO）在住房和办公室等方面的应用。gases such as HF、HCl、HNO型D23型D2、SO型D22型D2 and NH型D23型D2， etc. which give adverse effect to the production of semiconductors in the clean room， and offensive odors （NH型D23型D2， methylamines，etc.）在厕所和医院里，我认为它们是危险的。所要求的有效清除气体的技术的发展。这是必要的，以一种新的技术为基础的，以消除有害气体的类型的环球具有很高的能量效果。在这项研究中，一种新的去除设备是由使用扩散刮板方法开发的，并对去除危险气体的性能进行了调查。这可能是一种用简单设备制造各种气体的清除方法。这个拆卸设备是在5毫米间隔处进行50个扩散单元的聚合。Th（Th） ...

Various hazardous chemical concentrations has increased in the indoor air with the rapid growth of industrialization. For example, formaldehyde (HCHO) which arises in housing and office, etc., gases such as HF, HCl, HNOィイD23ィエD2, SOィイD22ィエD2 and NHィイD23ィエD2, etc. which give adverse effects to the production of semiconductors in the clean room, and offensive odors (NHィイD23ィエD2, methylamines, etc.) in the toilet and hospital, are considered to be hazardous. A development of efficient removal technology of these gases are requested. It is necessary to a develop new technology based on the cycloid type which has a high energy efficient to remove hazardous gases. In this study, a new removal equipment was developed by using diffusion scrubber method and investigated its performance of removal for hazardous gases. It is considered to be an epoch-making removal method of various gases by the simple equipment. This removal equipment is a conglomeration of 50 diffusion units at 5mm interval. Th … More e unit is made of 30x43cm rectangle frame which mounted a porous Teflon (PPTFE) membrane(0.1μm apertures, 70% porosity) in both sides. It is the simple structure which keep water as a removal solution in the PPTFE membrane frame (5mm width). By using only water as a removal solution, the removal of water-soluble gases such as HCHO, HCl, HNOィイD23ィエD2, SOィイD22ィエD2 and NHィイD23ィエD2 can be safely and conveniently removed. Water as a removal solution can be refined by using an ion-exchange resin, so that the removal equipment can be continuously operated for a long time. As a result, this method is more economical than the use of a chemical filter. For evaluating removal capability of gases (HCHO,NHィイD23ィエD2, SOィイD22ィエD2, HCl) by this removal equipment, experiments for measurements of the removal efficiency were carried out by using standard gases. As a result, the removal efficiencies were about 65% for HCHO, about 85% for NHィイD23ィエD2, about 80% for SOィイD23ィエD2 and about 90% for HCl at 1m/s of air velocity (275mィイD13ィエD1/h), respectively. Less
