The invention relates to a method and device for transformation of obstacle osmotic pressure into energy, which can find an application in energy production. The advantage of this method is that the pressure of the solution in the confined volume increases quickly to high values, which is achieved with a minimum amount of solvent and because of this the concentration is only slightly changed and easily restored. In this way, the increase in the pressure is achieved with a minimum consumption of solutions. Each release of the pressure of the solution, through a discharge of solution, is carried out upon reaching the optimal rate of pressure increase over time, which leads to an increase in efficiency. An additional contribution to the increase in efficiency is attributed to the maintaining of the concentration of the solution near the semipermeable barrier (5), which guarantees keeping the speed of the osmotic process. The method is carried out by pre-loading a vessel (1) with a solution with lower chemical potential (2), which is connected through a semipermeable membrane (5) to a main container (6) for solution with higher chemical potential (7), after which its volume is fixed through the closure of a valve (9). Through the semipermeable membrane (5) begins an osmotic process and into the main container (6) enters solvent, whereby the pressure of the solution in the main container (6) increases quickly, wherein the time for undergoing of the osmotic process under the selected concentrations of the solvents (2, 7), the operating temperature, are selected in such a way that the operating pressure in the main container (6) can reach a chosen value before the moment at which the rate of increase of the pressure reaches its maximum. Upon reaching the pre-selected value of the pressure, it is quickly released by actuating the first trigger valve (11), after which the pressure drops to its initial value, wherein the osmotic process continues and the pressure begins to increase again. 5 claims, 2 figures |
