Description

Ш известных шахтных печах дл варки стекла бассейн, в котором происходит осветление и гомогенизаци стекломассы, сообщаетс в газовой среде с соседним варочным и выработочным бассейнами, следовательно, осветление стекломассы проходит как и в ванных печах, в результате добавки в шахту осветлителей, воздействи температуры в зоне осветлени и продолжительности выдерживани в ней стекломассы.Three well-known glass furnaces for glass melting a pool in which the glass mass is clarified and homogenized is communicated in a gas atmosphere with the adjacent cooking and production pools, and therefore glass mass is brightened as in bath furnaces, as a result of addition of clarifiers to the mine, the temperature in the zone the clarification and the durability of glass mass in it.

Отличительной особенностью предлагаемого способа вл етс то, что дл облегчени процессов осветлени и гомогенизации стекломассы через нее пропускают продукты горени , барботирующие и гомогенизирующие стекломассу, а над зеркалом стекломассы в газовом пространстве бассейна создают вакуум, облегчающий удаление из стекломассы продуктов горени и газообразных компонентов шихты.A distinctive feature of the proposed method is that to facilitate the processes of clarification and homogenization of the glass mass, combustion products are bubbled through it, bubbling and homogenizing the glass mass, and above the glass mass mirror in the pool gas space, a vacuum is created that facilitates the removal of gas and gas components of the charge from the glass mass.

На чертеже показан разрез шахтной лечи с вакуумным бассейном дл осветлени и гомогенизации стекломассы.The drawing shows a mine mine cuts with a vacuum basin for clarification and homogenization of glass melt.

Устройство дл осуществлени предлагаемого способа выполнено в виде бассейн-вакуумкамеры 7, расположенной между загрузочной шахтой 2 и выработочной частью печи 3 и изолированной от них в газовом пространстве шамотными стенками 4, концы которых погружены на некоторую глубину в стекломассу.The device for carrying out the proposed method is made in the form of a pool-vacuum chamber 7 located between the loading shaft 2 and the working part of the furnace 3 and the chamotte walls 4 insulated from them in the gas space, the ends of which are immersed to a certain depth in the glass melt.

Еакуумкамера 7 над зеркалом стекломассы снабжена выт жными каналами 5 дл отсасывани продуктов горени .The vacuum chamber 7 above the glass mass mirror is provided with exhaust channels 5 for suctioning the combustion products.

Дымовые газы под действием избыточного давлени в шахте печи 2 прорываютс через стекломассу под 4 в вакуумкамеру 7, в которой происходит беспрерывное перемешивание стекломассы. Из вакуумкал еры отход щие газы отсасываютс эксгаустером через каналы 5.The flue gases under the action of overpressure in the shaft of the furnace 2 break through the glass mass under 4 into the vacuum chamber 7, in which continuous mixing of the glass mass occurs. From the vacuum, exhaust gases are sucked out by the exhauster through the channels 5.
