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.
