Embodiment Construction
[0017] figure 1 , figure 2 The best embodiment of the present invention for cement raw meal preheating system is given. The multiple cyclone heat exchangers of this preheating system are arranged in two rows from top to bottom, and there are five units in total. The airflow route of each row of cyclone heat exchangers is connected in series, that is, the air outlet of each cyclone heat exchanger in each row is connected with the air inlet of the previous unit cyclone heat exchanger in the same row; the airflow route of two rows of cyclone heat exchangers for parallel connection. The hot air from the rotary kiln enters the fifth unit (final unit) heat exchanger 5, and the hot air after separating the raw materials leaves the heat exchanger 5, and is divided into two paths and enters the fourth unit heat exchangers 4A and 4B in two rows. , and then enter the cyclone heat exchanger of the first unit on each column, and so on. The material flow route of each row of cyclone he...

The present invention is a high solid-gas ratio cross-flow heat treatment device for powdery materials, which is composed of multiple columns of cyclone heat exchangers arranged in parallel, the top heat exchanger of each column forms the first unit, and the uppermost heat exchanger of each column forms the first unit. The lower heat exchangers form the final unit, and the airflow route of each row of heat exchangers is in series. The logistics route of at least one unit in this device is connected in series, that is, the discharge port of the last cyclone heat exchanger of the previous unit is connected with the air inlet pipe of the first cyclone heat exchanger of this unit, and the first cyclone heat exchanger The discharge port of the cyclone heat exchanger is connected with the air inlet pipe of the second cyclone heat exchanger of this unit, and so on. The feature of this device is the combination of parallel airflow and cross-serial material flow, thereby improving the solid-gas ratio of the preheating unit and the heat exchange efficiency of the system. The invention can be widely used in powder material heat exchange systems in cement, chemical industry, metallurgy and other industries.
Description
technical field [0001] The invention belongs to the field of gas-solid phase heat exchange or heat reaction, in particular to a high solid-gas ratio cross flow heat treatment device for rapid heating, reaction and separation of powdery materials. Background technique [0002] Since the Czech engineer M.Voel-Jorgensen first submitted the patent for heating cement raw meal with a cyclone suspension preheater in 1932, the quality and output of the cement kiln have been greatly improved, and the heat consumption has been significantly reduced. The attention of researchers and equipment manufacturers has invested in the research and development of new preheating systems. The suspension preheating system used in the early stage is composed of multiple cyclone preheaters connected in series to form a single series of multiple monomers, such as the single series preheating system disclosed in Chinese patent CN1210965. The temperature of the exhaust gas discharged from the commonly ...
