A kind of desulfurizing tower
Technical field
The utility model relates to a kind of desulfurizing tower.
Background technology
The desulfurization principle of existing flue gas desulfur device is: the sulfur dioxide gas in the flue gas carries out demist by demister again after spraying layer carries out desulfurization.But existing flue gas desulfur device only is equipped with a demister, all demists on a demister of flue gas that all carry out after the desulfurization, cause to flue gas except fog effect undesirable.
The utility model content
Main purpose of the present utility model is to provide a kind of simple in structure, desulfurizing tower that demist is effective.
For addressing the above problem, the utility model adopts following technical scheme: a kind of desulfurizing tower comprises the desulfurizing tower body, and is arranged on the reserve pit of desulfurizing tower body below, and be arranged on the middle spraying layer of desulfurizing tower body, and be arranged on the demister of desulfurizing tower body top; Described desulfurizing tower body top is provided with two demisters of arranging up and down.
Further, described desulfurizing tower base side subordinate side is provided with smoke inlet, and described desulfurizing tower body upper end is provided with exhanst gas outlet.
Further, be provided with pallet between described spraying layer and the smoke inlet.
The beneficial effect of the utility model desulfurizing tower is: owing to be provided with two demisters of arranging up and down, the flue gas after spraying layer carries out desulfurization, after the demist through two demisters, the flue gas demist is effective, and the quality of flue gas is high.
Description of drawings
Fig. 1 is the front view of the utility model desulfurizing tower.
The specific embodiment
See also shown in Figure 1ly, a kind of desulfurizing tower of the present utility model comprises desulfurizing tower body 1, and is arranged on the reserve pit 2 of desulfurizing tower body 1 below, and is arranged on the spraying layer 3 in the middle of the desulfurizing tower body 1, and is arranged on the demister 4 of desulfurizing tower body 1 top; Described desulfurizing tower body 1 top is provided with two demisters 4 of arranging up and down, and after the demist through two demisters 4, the flue gas demist is effective, and the quality of flue gas is high.
Wherein, described desulfurizing tower body 1 sidepiece below is provided with smoke inlet 10, and described desulfurizing tower body 1 upper end is provided with exhanst gas outlet 11.Be provided with pallet 5 between described spraying layer 3 and the smoke inlet 10, pallet 5 is a kind of two phase countercurrent flow sieve trays, and the pressure drop that pallet 5 produces has further promoted the uniformity of smoke distribution, for the gas-liquid even contact of spraying layer scrubbing section provides more good assurance.
The beneficial effect of the utility model desulfurizing tower is: owing to be provided with two demisters of arranging up and down, the flue gas after spraying layer carries out desulfurization, after the demist through two demisters, the flue gas demist is effective, and the quality of flue gas is high.
The above only be the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
