PROBLEM TO BE SOLVED: To provide a solar thermal distillation apparatus which is the solar heat-used distillation apparatus (a water transportation apparatus or a water purification apparatus) and the energy utilization efficiency of which is increased so that the function of generating fresh water or transporting water is enhanced. SOLUTION: The solar thermal distillation apparatus comprises an aqueduct 10, an evaporation cap 12 and a condenser 16. A charcoal particle 24 is packed in a water retention space 22. A sealing faucet 26 having at least one water intake 26A is arranged at the bottom end of the aqueduct 10. An intermediate part 20 is constituted as an exposed transparent section. The water in a warming part 20A is warmed by sunlight 40, the upward movement of the warmed water is promoted and the evaporation function of the evaporation cap 12 is also promoted. The water in the evaporation cap 12 is evaporated by sunlight 42 and steam is condensed in the condenser 16. A water pouring mechanism 32 is used for forming a water column in the water retention space 22 in the initial state. Water can be transported to the horizontal direction by using the principle. A slender tube can be arranged in the aqueduct 10. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a wastewater treatment system capable of executing a chemical treatment in accordance with difference of a main constituent of a desorption gas to the desorption gas.SOLUTION: This wastewater treatment system 1 includes: an adsorption tank 11 for discharging a treatment liquid (E11) by cleaning raw water (E10) and discharging a desorption gas (G10) containing an organic solvent by desorption by a heating gas (G15); a detector 20 for detecting a property of the desorption gas (G10) when the desorption gas (G10) is discharged from the adsorption tank 11; a control part 30 for recognizing temporal change of the value of the property detected by the detector 20 as change of a main constituent of the desorption gas (G10) discharged from the adsorption tank 11 and selecting a chemical treatment to be executed to the desorption gas (G10) in accordance with the recognized change of the main constituent of the desorption gas (G10); and a treatment part 40 for executing the chemical treatment selected by the control part 30 to the desorption gas (G10) discharged from the adsorption tank 11.
摘要:
A heat exchanger plant for distillation comprises at least two parallel process lines (1) with at least two successive heat exchanger stages (2a, 2b) , which each comprises a plate package of heat exchanger plates provided in such a way that first plate interspaces for condensation and second plate interspaces for evaporation are formed. The heat exchanger stages form rows (8) with heat exchanger stages which lie after each other and transversely to the process lines. Each heat exchanger stage is adapted to perform condensation of steam and evaporation of a liquid, wherein they are supplied with steam to the first plate interspaces and a liquid to the second plate interspaces. The supplied steam is condensed to a liquid and the supplied liquid is evaporated and supplied to the first plate interspaces in the next heat exchanger stage for evaporation of a liquid supplied to the second plate interspaces in this next heat exchanger stage. The plant comprises a closed casing (10) , which encloses an inner space (11) in which the process lines are provided. The casing has, seen in a cross-section transversely to the process lines, a rectangular shape.
