The invention discloses a multi-tube Venturi type rotational flow double-tower spraying device, and relates to the technical field of flue gas dedusting. The multi-tube venturi type rotational flow double-tower spraying device comprises a first tower body, a second tower body, a base, a Venturi tube group and a spraying device, the first tower body and the second tower body are arranged at one end of the base, the second tower body is located at one side of the first tower body, the second tower body communicates with the bottom of the first tower body, and the Venturi tube group is arranged in the first tower body. During working, flue gas is input through the inlet in the top of the first tower body, and when the flue gas passes through the Venturi tube group, a higher operation effect can be obtained by adopting a lower throat tube airflow speed through the arranged Venturi tube group, so that the resistance is greatly reduced while the throat tube airflow speed is reduced; and the problem that a single-tube Venturi tube is large in resistance and poor in injection and diffusion effect is solved, and the total resistance of the dust removal device integrating the Venturi tube set, vortex, rotational flow and demisting is made to be smaller than 1200 Pa.
Description
technical field [0001] The invention relates to the technical field of flue gas dust removal, in particular to a multi-pipe Venturi type swirling double-tower spraying device. Background technique [0002] General wet dedusting complete sets of devices, such as spray tower, packing tower, turbulent ball tower, sieve plate tower, swirl plate tower, the gas-liquid mixing process is mainly based on inertial collision, only the Venturi tube dedusting device can achieve Ejection and diffusion are mainly used to achieve better gas-liquid mixing effect. Ejection diffusion is the ability to diffuse liquid to gas by negative pressure generated by high-speed gas flow. The ejection capacity is proportional to the square of the air velocity through the throat and inversely proportional to the diameter of the required throat (F∝U² / D). Because the larger the ejection range, the greater the movement resistance that the ejected liquid must overcome. Therefore, when the processing gas volu...
