Description

Известны решетки из жаростойкого бетона с газовыми каналами дл  печей кип щего сло , в которых провод т обжиг и спекани  в «кип щем слое материалов, не содержащих тепловыдел ющих компонентов (спекание нефелиновой и бокситовой щихты, обжиг известн ка, клинкера и т. п.). В таких решетках во врем  работы интенсивно зрозируют (прогорают) стенки газовых каналов, через которые с большой скоростью двигаетс  нагретый до 1400-1500° газовый поток. Этот процесс измен ет геометрические размеры газовых каналов, а следовательно, и живое сечение решетки. При этом часть материалов проваливаетс  нод рещетку, скорость газового потока снижаетс  и неравномерное распределение газов по площади решетки создает застойные зоны, где возможно сплавление материала.Lattices of heat-resistant concrete with gas channels for fluidized bed furnaces are known in which firing and sintering of materials that do not contain heat-generating components in the fluidized bed (sintering of nepheline and bauxite rocks, limestone, clinker, etc.). ). In such arrays, during operation, the walls of the gas channels are intensively zosulyaet (burn through) through which the gas flow heated to 1400-1500 ° moves at high speed. This process changes the geometric dimensions of the gas channels and, therefore, the living section of the lattice. At the same time, some of the materials fall through the lattice node, the gas flow rate decreases and the uneven distribution of gases over the lattice area creates stagnant zones, where material fusion is possible.

Предложенна  решетка не имеет этих недостатков за счет армировани  каналов керамическими вкладышами из фарфора, силиманита или алу да, что улучшает качество спекани  и обжига материалов и увеличивает срок эксплуатации нечей.The proposed grid does not have these disadvantages due to the reinforcement of the channels with ceramic inserts made of porcelain, silimanite or alumina, which improves the quality of sintering and roasting of materials and increases the service life of ignition.

На фиг. Г изображена рещетка, вид сверху; на фиг. 2-то же, в разрезе по А-А.FIG. G shows the grille, top view; in fig. 2 the same, in a section on A-A.

Решетка состоит из жаропрочного бетона 1 и керамических вкладышей 2.The grille consists of heat-resistant concrete 1 and ceramic liners 2.

Решетки с армированными газовыми каналами изготавливаютс  следующим образом: в опалубке решетки сверл т отверсти  и в них вставл ют металлические кондукторы, на которые надевают керамические вкладыши и затем производ т бетонирование решетки жаростойким бетоном. Когда бетон затвердеет кондукторы извлекают и снимают опалубку.Lattices with reinforced gas ducts are manufactured as follows: holes are drilled in the lattice formwork and metal conductors are inserted into them, which are put on ceramic liners, and then the concrete is grated with heat-resistant concrete. When the concrete is hardened, the conductors will remove and remove the formwork.
