Vertical farm ecological circulation system

Abstract

The invention relates to a vertical farm ecological circulation system comprising a multilayer vertical farm, a dividing wall rotary kiln, a carbon dioxide energy storage supply unit, an oxygenator, a power generator and a retorting gas separation unit; the multilayer vertical farm is provided with 1-1000 layers of racks, nutrient solution supply ports, straw collection transferring units, and carbon dioxide inlets; the straw collection transferring units are connected with the dividing wall rotary kiln; the dividing wall rotary kiln discharge ring is connected with a solid fuel burner; retorting gas outlets are connected with the retorting gas separation unit; condensed water outlets of the retorting gas separation unit are connected with a nutrient solution preparation tank; a smoke outlet of the power generator is connected with the carbon dioxide inlets; a burner ash outlet is connected with a dissolution tank; a dissolution tank outlet is connected with the nutrient solution preparation tank; nutrient solution supply ports are connected with the nutrient solution preparation tank. The vertical farm ecological circulation system can utilize various resources of the vertical farm in a recycle manner, thus effectively improving resource utilization rate, increasing vertical farm grains and other plants yield, and reducing agriculture production cost.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation and relates to a three-dimensional farm ecological cycle system. Background technique [0002] For a long time, the world's total grain output has been hovering around 2 billion tons per year. The world population is growing at a rate of 1.3% per year. Although the World Food Summit in 1996 and the UN Millennium Summit in 2000 both proposed the goal of halving the number of hungry people in the world by 2015, the number of hungry people in the world has continued unabated since this century. In 2000, 800 million people in the world were hungry, in 2007 it reached 923 million, and in 2009 it exceeded 1 billion. There is an irreconcilable contradiction between the continuous growth of population and the decreasing area of ​​arable land. [0003] In the process of increasing crop production, the proportion of improved cultivation measures is more than 60%, which has made outstanding contr...
