Determination of the Efficiency of Waste Gas Washing Equipments Used in Jewelery Workshop

Öz

During the processes where acid and cyanide are used in jewelery workshops, waste gases originates that hazardous in terms of human and environmental health and material. It is necessary to control these originated gas flows with suitable methods and equipment in the workshop and convert them to non-hazardous forms. For this purpose, waste gas washing equipment which can be used by various producers in jewelery workshops are produced. In this study, waste gas stream hazardous emissions removal efficiency of a system produced for this purpose was examined and the measures to be taken for the continuous efficiency were mentioned. According to results; it has been determined that the nitric acid emissions and the sulfuric acid emissions originated from the iron / copper solvation process are reduced by 94.5% and 88.3%, respectively, by means of waste gas washing system. It has been determined that cyanide emissions are reduced by 98.7% by washing the waste gases from the bombing process by means of washing system.  According to results, treated toxic gaseous emission concentrations were below the limit.

 values of Turkish Industrial Air Pollution Control Regulation (TIAPCR) and Netherlands Emission Guidelines for Air (NER).

KUYUM ATÖLYELERİNDE KULLANILAN ATIKGAZ YIKAMA EKİPMANLARININ VERİMLİLİKLERİNİN BELİRLENMESİ

Öz

Kuyum atölyelerinde asit ve siyanür kullanılan işlemler esnasında, insan ve çevre sağlığı ile malzeme üzerinde zararlı olacak nitelikte atık gazlar ortaya çıkmaktadır. Oluşan bu atık gaz akımlarının, oluştuğu atölye içinde uygun yöntem ve ekipmanlarla kontrol edilmesi ve zararsız hale getirilmesi gerekmektedir. Bu amaçla çeşitli üreticiler tarafından kuyum atölyelerinde kullanılabilecek atık gaz yıkama ekipmanları üretilmektedir. Yapılan çalışmada bu amaçla üretilmiş bir sistemin atık gaz akımı içerisindeki zararlı emisyonları giderme verimi incelenmiş ve verimin sürekliliğinin sağlanması için alınması gereken önlemler belirtilmiştir. Elde edilen sonuçlar incelendiğinde; kullanılan atık gaz yıkama sistemi sayesinde demir/bakır indirme işleminden kaynaklanan nitrik asit emisyonlarının %94,5, sülfürik asit emisyonlarının ise %88,3 oranında giderildiği belirlenmiştir. Patlatma işleminden kaynaklanan atık gazların yıkama sisteminde yıkanması ile siyanür emisyonun ise %98,7 oranında giderildiği tespit edilmiştir. Elde edilen sonuçlara göre arıtılmış toksik gaz emisyonları; Sanayi Kaynaklı Hava Kirliliğinin Kontrolü Yönetmeliği ve Hollanda Hava Emisyon Klavuzu’nda verilen limit değerlerin altında kalmıştır.
