Abstract

Изобретение относитс к воздухоподогревател м и вл етс усовершенствованием изобретени по авт. св. № 868270. Изобретение позвол ет повысить эффективность путем ликвидации застойны.х зон дисперсгюго материала. Холодный возду.х подаетс в устройство через коллектор (К) 5 и движетс вместе с дисперсным теплоносителем (Т) 9 по отсеку 3. Далее воздух пере.ходит в отсек 4, где нагреваетс теплом, полученным конвекцией от стенок корпуса I и от Т 9. Гор чий воздух отводитс через К 6. Т 9 через зазор 8 поступает в К 5 и вместе с потоком возду.ха поступает в отсек 3. Т нагреваетс за счет тепла, полученного излучением от стенок корпуса 1. В результате выполнени К 5 шириной, равной ширине подключенного к нему отсека 3, Т меньше времени пребывает в К 5, что способствует улучшению рециркул ции, предотвращению охлаждени Т и обеспечению полного его возврата в зону теплообмена. 1 л. SThe invention relates to air preheaters and is an improvement of the invention according to the author. St. No. 868270. The invention improves efficiency by eliminating stagnant zones of dispersive material. The cold air is fed into the device through the collector (K) 5 and moves together with the dispersed coolant (T) 9 through compartment 3. Then the air passes into compartment 4, where it is heated by the heat obtained by convection from the walls of housing I and from T 9 Hot air is discharged through K 6. T 9 through the gap 8 enters K 5 and together with the air stream enters compartment 3. T heats up due to heat received by radiation from the walls of housing 1. As a result of K 5 wide, equal to the width of the compartment connected to it 3, T less than the time resides in K 5, which contributes It improves recirculation, prevents cooling T and ensures its full return to the heat exchange zone. 1 l.

NJ The invention relates to devices for the use of secondary energy resources, can be applied, for example, for furnaces of engineering plants and is an improvement of the device according to the author. St. No. 868270. The aim of the invention is to increase efficiency by eliminating stagnant zones of dispersed material. The drawing shows the air heater, sheath, I view in section. The heater contains a vertical hollow body 1, divided by a vertical direction Yush, with a partition 2 on it, communicates, and in the upper part compartments 3 and 4, connected respectively to the supply w, him and tap w, he horizontal collectors 5 and 6, adjoining them to the bottom parts of housing 1 and separated from each other by a transverse partition 7 installed with a gap 8 relative to the longitudinal partition 2 of housing 1. The cavity of housing 1 is partially filled with dispersed heat carrier 9, and the inlet manifold 5 is made with a width equal to the width the compartment connected to it 3. The air heater works as follows. The cold air is supplied through the air inlet, the collector 5, and moves together with the dispersed coolant 9 through compartment 3, passes into compartment 4, where it is heated by the heat obtained by convection from the walls of the housing 1 and from the heat carrier 9. The removal of hot air is carried out through the collector 6. The coolant 9 through the gap 8 enters the collector 5 and, together with the air flow without staying in the collector 5, is supplied to the compartment 3. The coolant is heated by heat from the walls of the housing 1. As a result of the inlet manifold, the width Equal to the width of the connected compartment 3 decreases the residence time of the heat medium in the reservoir 5. This improves recirculation prevents the cooling heating medium and the heating medium provides full refund to the heat exchange zone. This increases the efficiency of the use of the coolant. Claims of the invention Air heater according to the author. St. No. 868270, characterized in that, in order to increase efficiency by eliminating stagnant zones of dispersed material, the supplying collector is made a width equal to the width of the compartment connected to it.
