Abstract

The invention provides a desulfurization tower flow field simulation method. The method is characterized in that a flow field simulation experiment system is established on the basis of a uniform gasinlet device, and detailed flow field analysis is carried out on a desulfurization tower. The uniform gas inlet device can improve the gas distribution in the desulfurization tower, so that the desulfurization efficiency is improved. According to the simulation method based on the experiment system, the measured spraying layer pressure drop serves as the simulation pressure drop, the resistance coefficient of a porous medium is determined through formula fitting, and a data basis is provided for equivalent replacement of the spraying layer, so simulation is more rigorous and accurate. In the simulation process, pressure sampling is carried out through section point taking, and the pressure drop of the spraying layer of the experiment system can be accurately obtained; the E value is used as a standard for judging the distribution uniformity of the gas in the tower, and the change condition of the E value of each section in the tower along with the tower height is obtained through quantitative calculation, so that the uniformity analysis result is intuitive and clear.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a flow field simulation method of a desulfurization tower. Background technique [0002] Wet desulfurization is the most effective flue gas desulfurization method in the chemical industry today. It has the advantages of high desulfurization efficiency, mature technology, and stable operation. Spray desulfurization tower is the core equipment of wet desulfurization. In the desulfurization tower, the SO2 in the inlet flue gas and the limestone slurry sprayed from the spray layer react with each other to realize the removal of SO2. [0003] The uniformity of flue gas distribution in the desulfurization tower is a key factor to maintain desulfurization efficiency. If the flue gas velocity fluctuates greatly on the same cross-section, the gas-liquid two-phase reaction in the high-speed zone will be insufficient, while the absorbent in the low-velocity zone will be excessive, resulti...
