Experimental Unit The experiments were performed in Energy Research Institute of Shandong Academy of Sciences key lab.
It concludes material circulating system, air induced draft/supply system, pressure and flow rate measuring system.
Then the particles return to the riser through the seal loop and form the material circulation.

According to the actual material properties, elastic modulus is set as 2 e + 11 [Pa] and 1.1 e+11 [Pa], Poisson ratio is 0.3 and 0.35.
According to the material properties, the definition of the friction coefficient is 0.1.
As we know, the friction coefficient is determined by the roughness of the joint surface when the materials of the contact pair are chosen.

The goal is to minimize waste, will park a plant or business for another plant by-products generated by the input or raw materials, and through the waste exchange, recycling, clean production methods, and ultimately the pollution of the park "zero emissions".
Eco-industrial park construction, should pay attention to science and technology contribute to economic growth, promote advanced technology, lower energy and raw materials, and ultimately less investment, high output, low pollution.
Recycling economy requires the organization of economic activity as "natural resources - products and supplies - renewable resources," the closed process, all raw materials and energy to be able to in the ongoing economic cycle to be a reasonable use and thus to economic activities on the natural environmental impact of control in the smallest possible degree.

THEORETICAL CONSTITUTIVE DAMAGE MODEL Extensive studies on damage properties of materials have been carried out in the past several decades.
BRIEF OUTLINE OF NUMERICAL TOOL AND TESTING MACHINE Numerical simulation is currently the most popular and effective method used for modeling deformation behavior of geo-materials.
RFPA 2D has two explicit features distinguishing it from other numerical methods: (1) By incorporating heterogeneity of material properties into the model, the RFPA code can simulate nonlinear deformation of a quasi-brittle or brittle behavior with an ideal brittle constitutive law for the heterogeneous materials; (2) By introducing a reduction of material parameters after element failure, the RFPA code can simulate strain-weakening and discontinuum mechanics problems in a continuum mechanics mode.
ACKNOWLEDGEMENT The study presented in this paper is funded by the China National Natural Science Foundation (No.50174013, 50134040 and 50204003).

At present, most of large blades are made of composite materials of fiber reinforced plastic (FRP), FRP has the merit of high specific strength, good fatigue properties and well damping properties.
The finite element model is shown in Fig.1. 1.2 Composite ply material As wind turbine blade layer material for FRP is anisotropic, in order to simulate its material characteristics and layer, we adopted composite material of SHELL99 to blade structure, anisotropy characteristic of composite material and layer distribution can be considered in the unit.
The mechanical properties of glass fiber reinforced plastic materials as shown in Tab.1: Tab.1 Material Character of FRP Material Ex Ey Gxy Poisson Density 7:1 FRP [Pa] [Pa] [Pa] 0.22 1950[kg/m3] 1:1 FRP [Pa] [Pa] [Pa] 0.14 1950[kg/m3] 2 Modal frequency analysis of the blade 2.1 Additional stiffness The inertial centrifugal force caused by the blade rotary motion, wind load and other loads of the coupling action increases when the wind turbine rotating, it’s increasing the blade stiffness as well appearing stiffening effect.
