The invention relates to the technical field of flue gas purification, in particular to a coke oven flue gas desulfurization and dedusting system and method. The coke oven flue gas desulfurization anddedusting system comprises a heat exchanger, a desulfurization reaction unit, a dedusting unit and a fan; the heat exchanger comprises an original flue gas pipeline and a purified flue gas pipeline;the original flue gas pipeline, the desulfurization reaction unit and the dedusting unit are sequentially connected, a purified flue gas outlet of the dedusting unit is communicated to an inlet of thepurified flue gas pipeline, and an outlet of the purified flue gas pipeline is connected to the fan. The low temperature and intermittent characteristics of the coke oven flue gas discharge are combined, the temperature difference between purified flue gas and original flue gas is used, after the original flue gas is heated in the heat exchanger, the original flue gas is sent to the desulfurization reaction unit for desulfurization reaction, heat from the purified flue gas emitted is effectively utilized, thereby saving energy.

The invention provides a compressed convolutional neural network-oriented parallel convolution operation method and apparatus. The method comprises the steps of determining an adopted operation mode according to input control signal convolution data shift chain length selection, accumulated offset enabling and convolution calculation enabling; and by adopting two serial shift register chains, inputting convolution data, convolution parameters and channel offset, and performing 3X3 and 1X1 convolution operation at the same time for a same input convolution data stream. According to the method, a multiplier, an accumulator, a parameter register and an offset register are added only based on original serial shift register chain-based 3X3 convolution operation; the realization method is simple; the executive efficiency is high; and the convolution operation in a compressed neural network algorithm can be effectively accelerated. According to the apparatus, a plurality of characteristic graphs can be output at the same time through simple hardware unit expansion and copying; and the apparatus has the advantages of low power consumption, high function unit utilization rate and high processing speed.

A water-soluble fertilizer. The invention belongs to the field of a crop fertilizer and specifically relates to a nano-scale multi-nutrient water-soluble fertilizer. The water-soluble fertilizer is composed of urea, monoammonium phosphate, potassium dihydrogen phosphate, Chinese medical stone, dolomite and other additives. The water-soluble fertilizer is prepared by the following steps: firstly micronizing Chinese medical stone and dolomite and carrying out water dissolution treatment, dissolving the mixture in water and simultaneously adding urea, monoammonium phosphate and potassium dihydrogen phosphate to be dissolved together, sending the mixture into a high pressure homogenizer for homogenization and refining to nanometers, adding the additives and mixing, concentrating and crystallizing, filtering and drying, crushing and packaging to obtain the nano-scale multi-nutrient water-soluble fertilizer. The water-soluble fertilizer has advantages of uniform color and granularity, adequate nutrient and fine particles and helps plants absorb nutrients. By the use of the water-soluble fertilizer, absorption and utilization of the fertilizer are raised for crops. Meanwhile, soil structure can be improved. Soil hardening is prevented, soil granulation is enhanced, microbial activity of plant roots is raised, and product quality of crops is promoted. The water-soluble fertilizer has good water solubility, is irrigated with water, will not block pipelines, and is suitable for integration of water and fertilizer.
