(54) ВОЗДУХОПОДОГРЕВАТЕЛЬ С СЫПУЧИМ ПРОМЕЖУТОЧНЫМ ТЕПЛОНОСИТЕЛЕМ(54) AIR HEATER WITH BULK INTERMEDIATE HEAT CARRIER
Изобретение относитс к аппарата нагрева дуть с промежуточным тепло носителем, использующим тепло отход щих запыленных газов отражательны печей, переплавл ющих лом цветных м таллов, с последующей очисткой их о пыли. Известны воздухоподогреватели с сыпучим промежуточным теплоносителе перемещаемым под действием силы т жести , содержащие верхнюю и нижнюю камеры, снабженные патрубками подвода и отвода греющего газа и возду ха, в первой из которых размещен теплообменник,а другой - объединен:ные попарно жалюзийные решетки, обр зующие каналы дл сыпучего теплоносител , подсоединенные к бункеру и подъемнику 1. , Недостаток известных воздухоподогревателей заключаетс в загр знении частичками пьши труб и промежуточного теплоносител , спекании частичек при высоких температурах и отложении на желобах и на стенках шахты, вследствие чего, нарушаетс ритм работы воздухоподогревател . Целью изобретени вл етс повыше ние степени очистки греющего газа, Цель достигаетс тем, что тепло обменник выполнен в виде симметрично расположенных секций, одна из полостей каждой из ко -орых подключена к патрубкам подвода и отвода воздуха, а друга - к патрубку подвода греющего газа и соединена через газоход, расположенный между секци ми с каналами нижней камеры, подсоединенными к патрубкам отвода греющего газа. На фиг. изображен воздухоподогреватель; на фиг. 2 - сечение по А-А на фиг. 1. Воздухоподогреватель содержит корпус 1, теплообменник 2, камеры 3 и 4, распределитель 5, ограничитель б, газоход 7, промежуточный теплоноситель 8, жалюзийные решетки 9, бункер 10, элеватор 11, фильтр 12, патрубки 13 и 14 дл подвода греющего газа, патрубки 15 и 16 дл отвода греющего газа, патрубок 17.дл подвода Hcirpeваемого воздуха, патрубок 18 дл его отвода, бункер 19. Воздухонагреватель работает следующим образом. Греющие (дымовые) газы через патрубки 13 и 14 подаютс в камеру 3 и отдают свое тепло теплообменнику 2The invention relates to a heating apparatus to blow with an intermediate heat carrier, using the heat of waste dusty gases from reflective furnaces, remelting scrap of colored tal, followed by cleaning them with dust. Air heaters with a flowable intermediate heat transfer medium under the action of gravity are known, containing upper and lower chambers, equipped with nozzles for supplying and discharging heating gas and air, in the first of which a heat exchanger is placed, and the other is combined: pairwise louvre lattices, the forming channels for bulk heat transfer fluid, connected to the hopper and lift 1. The disadvantage of the known air heaters is that they are contaminated with pipes and intermediate heat carrier particles, sintering particles At high temperatures and deposition on the grooves and on the walls of the mine, as a result, the rhythm of the air heater is disturbed. The aim of the invention is to increase the degree of purification of the heating gas. The goal is achieved by the fact that the heat exchanger is made in the form of symmetrically arranged sections, one of the cavities of each of which are connected to the air inlet and outlet pipes, and the other to the gas inlet pipe. connected through a duct located between the sections with the channels of the lower chamber connected to the heating gas outlet nozzles. FIG. an air heater is depicted; in fig. 2 is a section along A-A in FIG. 1. The air preheater includes a housing 1, a heat exchanger 2, chambers 3 and 4, a distributor 5, a stop valve b, a flue 7, an intermediate heat carrier 8, louvered grilles 9, a hopper 10, an elevator 11, a filter 12, pipes 13 and 14 for supplying heating gas, pipes 15 and 16 for removal of heating gas, pipe 17. for supplying Hcirped air, pipe 18 for its removal, hopper 19. The air heater works as follows. Heating (flue) gases through the pipes 13 and 14 are fed into the chamber 3 and give their heat to the heat exchanger 2
