Compact and efficient heat exchange equipment for nuclear power plants

Abstract

The invention belongs to the technical field of heat exchange of nuclear power plants, and particularly relates to compact and efficient heat exchange equipment for nuclear power plants. The equipment comprises a plurality of layers of cooling water side heat exchange plates (15) and reactor coolant side heat exchange plates (14) which are arranged in a staggered and laminated manner, and spray water heat exchange pipes (16) penetrating through the cooling water side heat exchange plates (15) and the reactor coolant side heat exchange plates (14). The whole part is manufactured by adopting an additive manufacturing technology. the integrated processing can enhance the strength of the equipment and enable the equipment to bear large working pressure, and meanwhile, the good sealing performance is ensured, the heat exchange between fluids can be realized when two different working conditions act respectively, the system design is simplified and optimized, and the economical efficiency of a nuclear power plant is improved.

Description

technical field [0001] The invention belongs to the technical field of heat exchange in nuclear power plants, and in particular relates to compact and efficient heat exchange equipment for nuclear power plants. Background technique [0002] Nuclear power plants require a large number of heat exchange equipment during operation, almost all of which are traditional shell-and-tube heat exchange equipment and plate heat exchange equipment that realize heat exchange between two fluids. However, shell-and-tube heat exchange equipment has large volume, low thermal efficiency, and poor economy; plate heat exchange equipment has many sealing structures, low pressure bearing capacity, and poor safety. Moreover, with the development of nuclear power technology and the emergence of micro-reactors, small heaps and other reactor types, there are higher requirements for heat exchange equipment in terms of heat exchange efficiency, safety, and economy. A single traditional heat exchange eq...

AI Technical Summary

Problems solved by technology

A single traditional heat exchange equipment can only realize the heat exchange between two fluids functionally, and cannot be used or used in multiple heat exchange conditions at the same time; limited by its own structure and manufacturing methods, it cannot improve heat exchange efficiency

In short, the problems of traditional heat exchange equipment are not conducive to reducing the size of the nuclear power plant building, optimizing the layout space, and improving the economy and safety of nuclear power plants
