Abstract

Zbiornik gromadzenia popiołów cynkowniczych znajdujący się w praktycznej odległości od wanny cynkowniczej, charakteryzuje się tym, że tworzą go dwie komory (4, 6), gdzie pierwsza komora (4) posiada zasyp zbiornika (2) nad wanną cynkowniczą (1), nad którym znajduje się wentylator wysokociśnieniowy (8) połączony z kanałem pneumatycznym (3) dostarczającym popiół do pierwszej komory (4) zbiornika, w której znajduje się cyklon (5) łączący drugą komorę (6) zbiornika z multicyklonem (7) oraz filtr pulsacyjny (9) pieca cynkowniczego. W innej odmianie zbiornik charakteryzuje się tym, że tworzą go dwie komory (4, 6), pozwalające na praktycznie całkowite wydzielenie popiołów ze strumienia powietrza, umożliwiające wydzielenie w pierwszej jego komorze, cięższej, metalicznej frakcji popiołu, która jest w tej samej ocynkowni poddana recyklingowi poprzez rozścielenie na lustrze kąpieli cynkowniczej i poddana rafinacji. Pierwsza komora (4) posiada cyklon (5), a druga komora (6) multicyklon (7) napędzany przez wentylator wysokociśnieniowy (8) odprowadzający strumień powietrza z resztkami pyłów z popiołów do komory filtra pulsacyjnego (9) pieca cynkowniczego. Komory (4, 6) wyposażone w przepustnice i kanały wsypowe (10) umożliwiają pakowanie popiołów. Sposób napełniania zbiornika w procesie cynkowania ogniowego charakteryzuje się tym, że zbiornik jest napełniany w sposób pneumatyczny z jednoczesnym wychłodzeniem, poprzez załadunek zgarniętych na brzeg wanny cynkowniczej (1) popiołów, perforowaną łopatką do zasypu (2), w którym podciśnieniowo podawane są kanałem (3) do pierwszej komory (4) zbiornika, w której cyklon (5) rozdziela frakcje cięższą popiołów, a frakcja lekka jest transportowana do drugiej komory (6) zbiornika, w której multicyklon (7) wydziela frakcje pylistą, która opada w komorze, a prawie oczyszczone powietrze kierowane jest przez wentylator wysokociśnieniowy (8) do komory filtra pulsacyjnego (9) obsługującego piec cynkowniczy.The galvanizing ash collection tank, located at a practical distance from the galvanizing tank, is characterized by the fact that it consists of two chambers (4, 6), where the first chamber (4) has a tank hopper (2) above the galvanizing tank (1), above which there is consists of a high-pressure fan (8) connected to a pneumatic channel (3) supplying ash to the first chamber (4) of the tank, in which there is a cyclone (5) connecting the second chamber (6) of the tank with the multi-cyclone (7) and the pulse filter (9) of the furnace galvanizing. In another version, the tank is characterized by two chambers (4, 6), allowing for virtually complete separation of ashes from the air stream, enabling the separation in the first chamber of a heavier, metallic fraction of ash, which is recycled in the same galvanizing plant by spreading a galvanizing bath on the mirror and refining it. The first chamber (4) has a cyclone (5), and the second chamber (6) has a multi-cyclone (7) driven by a high-pressure fan (8) discharging an air stream with ash dust residues into the pulsation filter chamber (9) of the galvanizing furnace. Chambers (4, 6) equipped with dampers and feed channels (10) enable ash packing. The method of filling the tank in the hot-dip galvanizing process is characterized by the fact that the tank is filled pneumatically with simultaneous cooling, by loading the ashes scraped onto the edge of the galvanizing bath (1) with a perforated shovel into the charge (2), where they are fed under vacuum through the channel (3). ) to the first chamber (4) of the tank, where the cyclone (5) separates the heavier fraction of ashes, and the light fraction is transported to the second chamber (6) of the tank, where the multicyclone (7) releases the dusty fraction, which falls in the chamber and almost the purified air is directed by a high-pressure fan (8) to the pulsation filter chamber (9) serving the galvanizing furnace.
