Tank bottom structure of solid medium storage tank for combined type photo-thermal power generation and construction method of tank bottom structure
The invention discloses a composite solid medium storage tank bottom structure for photo-thermal power generation, which comprises a concrete foundation, a tank bottom steel shell and a tank wall steel shell, the tank bottom steel shell and the tank wall steel shell are arranged above the concrete foundation, and a tank bottom outer thermal insulation layer and a tank wall outer thermal insulation layer are respectively arranged between the tank bottom steel shell and the concrete foundation and on the outer surface of the tank wall steel shell; a tank wall inner heat insulation layer, a tank wall inner heat preservation layer and a tank wall working layer which are all located on the tank bottom steel shell are sequentially arranged on the inner surface of the tank wall steel shell from outside to inside, and a tank bottom inner heat preservation layer and a tank bottom working layer are sequentially arranged on the inner surface of the tank bottom steel shell from bottom to top; a conical slope forming an acute angle with the horizontal direction is arranged on the tank bottom working layer, an outlet is formed in the middle of the tank bottom steel shell, an outlet connected with the outlet vertically penetrates through the tank bottom inner heat preservation layer and the tank bottom working layer, and an inlet of the outlet is connected with the lower end of the slope. The problems that an existing steel storage tank is high in cost, prone to corrosion and not resistant to abrasion, and the welding portion of the tank bottom is damaged due to thermal stress are solved.
本发明公开了一种复合式光热发电用固体介质储罐罐底结构，包括混凝土基础和设置于混凝土基础上方的罐底钢壳和罐壁钢壳，罐底钢壳与混凝土基础之间以及罐壁钢壳外表面上分别设置有罐底外保温层和罐壁外保温层，罐壁钢壳内表面由外至内依次设置有均坐落于罐底钢壳上的罐壁内绝热层、罐壁内保温层和罐壁工作层，罐底钢壳内表面由下至上依次设置有罐底内保温层和罐底工作层；罐底工作层上设置有与水平方向夹角为锐角的锥形斜坡，罐底钢壳中部开设有出口，罐底内保温层和罐底工作层上竖直贯穿有与出口衔接的出口，出口入口与斜坡下端衔接。本发明解决了现用钢质储罐带来的高成本、易腐蚀、不耐磨损、热应力造成罐底焊接部位损伤等问题。
