Harmless resourceful treatment method of flue gas desulfurization gypsum slag
The invention discloses a harmless resourceful treatment method of flue gas desulfurization gypsum slag, which comprises the following steps: step 1, forming gypsum slurry from flue gas desulfurization gypsum slag after flue gas is purified by a spray tower; 2, the gypsum slurry enters a mixing and stirring tower through a cyclone; 3, adding a stable curing agent into the mixing and stirring tower, and fully mixing the stable curing agent with the gypsum slurry; 4, the fully mixed stable curing agent and gypsum slurry enter a forming machine to be formed, and a formed gypsum board is manufactured; and fifthly, the gypsum board is dried through a drying machine. The method has the advantages that the produced gypsum slurry is not subjected to dehydration treatment and is directly mixed with the stable curing agent, so that wastewater is not generated, and the treatment cost is greatly reduced; the curing effect is good; the stirring radius of the stirring blades in the mixing and stirring tower can be adjusted according to needs, the mixing effect is good, and the stable curing agent enters the spraying bin from the vertical pipe, is directly sprayed into the mixing and stirring tower through the high-pressure fan and can be fully mixed with gypsum slurry.
本发明公开了一种烟气脱硫石膏渣的无害资源化处理方法,其包括以下步骤,步骤一、经喷淋塔净化烟气后的烟气脱硫石膏渣形成石膏浆液;步骤二、石膏浆液经旋流器进入混合搅拌塔;步骤三、在混合搅拌塔内加入稳定固化剂,稳定固化剂与石膏浆液充分混合;步骤四、充分混合后的稳定固化剂和石膏浆液进入成型机成型,制作成型石膏板;步骤五、通过烘干机对石膏板进行烘干。本发明的优点:产出的石膏浆液不进行脱水处理,直接与稳定固化剂混合,这样不产生废水,极大的降低了处理成本;固化效果好;混合搅拌塔中搅拌叶片可根据需要调整搅拌半径,混合效果好,稳定固化剂从垂直管进入喷料仓,通过高压风机直喷到混合搅拌塔内,能够和石膏浆液充分混合。
