Wet desulphurization equipment for coal-fired flue gas

The utility model discloses coal-fired flue gas wet desulfurization equipment which comprises a desulfurization tower, a filter box, a first ladder surface collecting plate, a spraying mechanism and a collecting mechanism, and a first gas inlet pipe is embedded in the middle of one side wall of the desulfurization tower. The device is provided with the collecting mechanism, the particle filter screen is knocked by the eccentric block on the second motor, and dust particles on the particle filter screen fall into the collecting box, so that the dust particles in the coal-fired flue gas are filtered and collected, the device is simple to operate, the sludge amount in the device is reduced, the load of the device is reduced, and the spraying mechanism is arranged, so that the device is convenient to use. Coal-fired flue gas is fully mixed with desulfurizer solution spray at the bottom of the first ladder-surface collecting plate, desulfurization of the coal-fired flue gas is achieved, then the flue gas enters th
