Abstract

Сушильный агрегат для контактной сушки сыпучих материалов, состоящий из теплоизолированного корпуса, теплообменника, системы отопления, ворошителей, отличающийся тем, что корпус состоит из трех наклонных ступеней, установленных разнонаправлено под различными углами, внутри которых установлены двухъярусные теплообменники с пятью полостями из которых две (II и IV) сквозные по всем трем ступеням и заполнены сыпучим материалом (например, золой), а три (I, III и V) являются основой трех теплообменников, установленных в трех ступенях, по которым из топки подают дымовые газы (около 600°С) по следующей схеме: в I и III полости теплообменников верхней и нижней ступеней и в III и V полости средней ступени корпуса агрегата, а отработанные дымовые газы через полости V верхней и нижней ступеней и через полость I средней ступени эвакуируют концевым дымососом, а перемешивание и перемещение материала (золы) по II и IV полостям осуществляются группой четырехлопастных, двухярустных ворошителей, смонтированных перпендикулярно к поверхности корпуса.A drying unit for the contact drying of bulk materials, consisting of a thermally insulated body, heat exchanger, heating system, agitators, characterized in that the body consists of three inclined steps installed in different directions at different angles, inside of which are two-tier heat exchangers with five cavities, of which two are (II and IV) through all three steps and filled with bulk material (for example, ash), and three (I, III and V) are the basis of three heat exchangers installed in three steps, according to which the flasks supply flue gases (about 600 ° C) according to the following scheme: in the I and III cavities of the heat exchangers of the upper and lower stages and in the III and V cavities of the middle stage of the unit body, and the exhaust flue gases through the cavities V of the upper and lower stages and through the cavity I the middle stage is evacuated with an end exhaust fan, and the mixing and movement of material (ash) along the II and IV cavities is carried out by a group of four-blade, two-grain agitators mounted perpendicular to the surface of the body.
