Combined salt-separation water-fertilizer integrated device

Abstract

The invention disclosed a combined salt-separation water-fertilizer integrated device. The device comprises a sunshine energy-collection device, a heat energy conducting mechanism, an evaporation andreverse osmosis mechanism, a concentrated liquid backflow mechanism, a reverse osmosis pure water flow guiding mechanism, a residual steam utilization mechanism, an underground saline water flow guiding mechanism, a pressure detection mechanism, a purified water storage mechanism and a water-fertilizer integrated drop irrigation mechanism, wherein the sunshine energy-collection device comprises aplurality of sunshine energy-collection mirrors which are connected in series; and the evaporation and reverse osmosis mechanism comprises a steam power cylinder, a reverse osmosis assembly and a middle linkage component. By producing fresh water through a sunshine energy-collection manner and a reverse osmosis manner, the combined salt-separation water-fertilizer integrated device has the outstanding advantages that the cost is low, the utilization rate of land is substantially increased, and the economic benefit is remarkable; by producing pure salt through salt-water separation, the economic added value of the device is greatly increased; by pumping underground water, the underground water level is lowered, the desalting speed of soil is high, and the range is wide; and the water-fertilizer integration is realized through the combination of drop irrigation.

Description

technical field [0001] The invention relates to the field of improvement and utilization of saline-alkali land, in particular to a combined salt separation, water and fertilizer integration device. Background technique [0002] The groundwater in coastal saline-alkali land is very rich, but its salt content is extremely high, so it cannot be used to irrigate farmland. At present, the main method of improving saline-alkali land is to build large-scale reservoirs to store fresh water, to make large-scale matching ditches, and to rely on high-pressure salt. This improvement method has huge investment, low land utilization rate and poor economic benefit. Contents of the invention [0003] Aiming at the defects of the prior art, the present invention provides a combined salt separation, water and fertilizer integration device with low investment, high land utilization rate and good economic benefits. [0004] Its technical scheme is: including sunlight energy gathering mechan...
