POND-EVAPORATOR OF MINERALIZED DRAINAGE FLOW Russian patent published in 2019 - IPC E02B11/00 

FIELD: agriculture.

SUBSTANCE: invention relates to irrigated agriculture and will find application in utilization of mineralized drain flow of irrigation and reclamation systems. Pond-evaporator of mineralized drainage flow is connected by means of water regulating structures with supply channel, is divided into compartments, equipped with system of vertically installed wind-guiding partitions and device for direction of air flow to water surface. Compartments are equipped with structural modules arranged within pond-evaporator compartments and on its bank, and contain support frame with beams, on which evaporation elements in form of spiral of screw from hydrophilic open-porous material are vertically fixed. Pump station is installed on pond bank, pressure pipeline of which is connected to distributing pipelines laid along beams and equipped with water outlets at each evaporation element. Besides, support frame of each structural module can be arranged on foundation blocks above surface of water or shore, each evaporation element can have black colour or close to it by reflecting ability, and in lower part of evaporating element can be mounted device for collection of salts. Structural module located on the shore is equipped with a system of return water withdrawal into pond-evaporator compartments.

EFFECT: proposed design of pond-evaporator provides intensification of evaporation process due to increased area of evaporating surface and improvement of heat-and-energy sharing between air flows and moistened evaporation elements.
