The invention provides an intelligent processing device. The intelligent processing device comprises a processor and a direct memory access controller. The processor generates a read instruction to read data from a memory. The address generation circuit generates a plurality of first address signals to the memory according to the first configuration parameter and the reading instruction. The dataprocessing unit receives data output by the memory in response to the plurality of first address signals, and performs data interception processing on the data received from the memory according to the reading instruction and the first configuration parameter. And the data interface outputs the data processed by the data processing unit to the processor. The plurality of first address signals comprise a plurality of discontinuous address signals, so that data read from the memory corresponds to an n-dimensional data block after being processed by the data processing unit, and n is a positive integer greater than 1. The access modes of the intelligent processing device to the storage space are more flexible and diverse, and instruction resources for accessing the storage space can be saved.

The invention relates to a method for recycling dibasic acid byproducts from adipic acid waste liquor, which comprises steps as follows: dibasic acid waste liquor is preheated by a preheater and enters a climbing film evaporator; the concentrated solution from the climbing film evaporator naturally flows to a falling film evaporator; the discharged material from the bottom of the falling film evaporator is in a molten state; after a seal tank is subjected to vacuum isolation, a safe evaporating tank is operated under normal pressure; and the liquor naturally flows to the safe evaporating tank to be buffered, and enters a flaker to form flakes, thereby obtaining the dibasic acid flake byproducts. Compared with the prior art, the invention enhances the evaporization efficiency, lowers the steam consumption, implements continuous operation of evaporative concentration of adipic acid waste liquor, implements continuous discharge to avoid the possibility of explosion due to overpressure of equipment, ensures the discharge requirement for water content and the stable operation of the flaker, can adapt to great incoming material fluctuation or steam pipe network fluctuation, reasonably utilizes the energy, and lowers the comprehensive energy consumption of the products.
