The invention provides a gypsum board production line, and a gas treatment device and method thereof. The gas treatment device comprises: an aeration tank; a solution storage tank connected with an automatic regulating valve, wherein the solution storage tank is used for storing an alkaline solution with a preset concentration, and the automatic regulating valve is used for supplying the alkalinesolution into the aeration tank; a gas supply device, wherein a gas outlet of the gas supply device extends into the aeration tank and is used for introducing to-be-treated gas containing acid gas into the aeration tank, and the to-be-treated gas is aerated in the alkaline solution, so that the acid gas and the alkaline solution are subjected to a neutralization reaction; a detection device arranged above the aeration tank and used for detecting discharge data of the acid gas overflowing after aeration; and a control device electrically connected with the automatic regulating valve and the detection device and used for controlling the opening degree of the automatic regulating valve according to the discharge data and a preset algorithm. According to the gas treatment device, the problemsthat a calcium hydroxide solution is seriously wasted and the gas outlet of the gas supply device is blocked by calcium carbonate can be solved.
Description
technical field [0001] The invention relates to the technical field of gypsum board production, and more specifically, to a gas treatment device for a gypsum board production line, a gypsum board production line and a gas treatment method for a gypsum board production line. Background technique [0002] Gypsum board is a kind of decorative board made of building gypsum as the main raw material. It has the advantages of light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire prevention. [0003] Raw materials and gases to be treated from thermal coal furnaces contain SO 2 and other acid gases, SO 2 Such acid gases need to be removed through a desulfurization tower to meet emission requirements. The way to remove acid gas by gas treatment device is: [0004] Such as figure 1 As shown, there is an aeration tank 10 in the desulfurization tower, and an alkaline solution (calcium hydroxide solution) is stored in the soluti...
