Abstract
The desalination wave station designed by Ovsyankin is intended for desalination of sea water by a reverse osmosis system based on renewable energy of sea waves and of currents in the open sea and relates to the fields of hydropower and water purification. The essence of the proposed invention is creating a reliable desalination wave station having a stably high output in a wide range of wave parameters. In the desalination wave station which comprises an energy-absorbing element in the form of a flexible longitudinal body, hydraulic transmission where the rotational energy of the energy-absorbing elements is converted into the energy of pressurised sea water movement by means of hydraulic cylinders, the problem of interest is solved by the inclusion of desalination units comprising holders for reverse osmosis membranes which cut in (cut out) sequentially in response to a change in the wave behaviour in the sea area.
Description
ВОЛНОВАЯ ОПРЕСНИТЕЛЬНАЯ СТАНЦИЯ ОВСЯНКИНА OVSYANKIN WAVE DESALINATION STATION
Изобретение относится к областям гидроэнергетики и очистке воды и может быть использовано для опреснения морской воды за счет возобновляемой энергии морских волн и течений в открытом море. The invention relates to the fields of hydropower and water purification and can be used for desalination of sea water due to the renewable energy of sea waves and currents in the open sea.
Известна волновая электростанция с гидравлической трансмиссией, которая содержит энергопоглощающие элементы, выполненные в виде гибкого продольного тела, направляющие,, рабочий вал достаточной плавучести, зонтиковидные успокоители, систему погружения и гидравлическую трансмиссию, где энергия вращения энергопоглощающих элементов преобразуется с помощью гидроцилиндров в энергию движения морской воды под давлением ( Овсянкин В. В. и др. Патент Украины Ns 107856). Known wave power plant with a hydraulic transmission, which contains energy-absorbing elements made in the form of a flexible longitudinal body, guides ,, working shaft of sufficient buoyancy, umbrella-shaped dampers, immersion system and hydraulic transmission, where the energy of rotation of the energy absorbing elements is converted with the help of hydraulic cylinders into the energy of movement of sea water under pressure (Ovsyankin V.V. et al. Patent of Ukraine Ns 107856).
Недостатками этой станции являются: The disadvantages of this station are:
- ограниченная область применения в качестве энергетической установки, подающей морскую воду под давлением, из-за нестабильности параметров водного потока в гидравлической трансмиссии, что, в частности, при опреснения морской воды системой обратного осмоса приводит к низкой производительности; - limited area of application as a power plant supplying seawater under pressure, due to the instability of the parameters of the water flow in the hydraulic transmission, which, in particular, when seawater is desalinated by the reverse osmosis system, leads to low productivity;
- отсутствие в конструкции технических решений, исключающих воздействие вредоносного цветения водорослей на фильтрующие элементы. - the lack of technical solutions in the design that exclude the impact of harmful algae bloom on the filter elements.
Задачей изобретения является придание станции свойств, позволяющих расширить область ее прикладного использования, а именно, эффективно
работать, как волновая опреснительная станция, на энергии морских волн и течений. The objective of the invention is to impart properties to the station, allowing to expand the area of its applied use, namely, effectively work as a wave desalination station, using the energy of sea waves and currents.
Поставленная задача достигается тем, что в известной конструкции волновой станции, содержащей энергопоглощающие элементы, выполненные в виде гибкого продольного тела, направляющие, рабочий вал достаточной плавучести, зонтиковидные успокоители, систему погружения и гидравлическую трансмиссию, где энергия вращения энергопоглощающих элементов преобразуется с помощью гидроцилиндров в энергию движения морской воды под давлением, ресивер высокого давления гидравлической трансмиссии по всей длине имеет несколько точек выхода с запорными устройствами, к которым рукавами высокого давления подсоединяются опреснительные секции с держателями мембран обратного осмоса, последовательно подключающиеся (отключающиеся) по мере изменения расхода водного потока в ресивере или волновой обстановки в акватории, при этом, давление в ресивере поддерживается в заданном интервале системой клапанов. The task is achieved by the fact that in the known design of the wave station, which contains energy-absorbing elements made in the form of a flexible longitudinal body, guides, a working shaft of sufficient buoyancy, umbrella-shaped dampers, an immersion system and a hydraulic transmission, where the rotational energy of the energy absorbing elements is converted using hydraulic cylinders into energy movement of seawater under pressure, the high-pressure receiver of the hydraulic transmission along its entire length has several outlet points with locking devices, to which desalination sections with reverse osmosis membrane holders are connected with high-pressure hoses, which are connected (disconnected) in series as the flow rate of the water flow in the receiver changes or wave situation in the water area, while the pressure in the receiver is maintained in a given interval by a system of valves.
Поставленная задача достигается так же тем, что волновая станция содержит заборный ресивер, соединенный с гидроцилиндрами гибкими гидравлическими рукавами, в который вода всасывается через фильтр предварительной очистки разряжением, создаваемым поршнями гидроцилиндров, а плоскость забора воды находится ниже области распространения вредоносного цветения водорослей.The task is also achieved by the fact that the wave station contains an intake receiver connected to the hydraulic cylinders by flexible hydraulic hoses, into which water is sucked through a pre-filter by a vacuum created by the pistons of the hydraulic cylinders, and the water intake plane is below the area of distribution of harmful algal blooms.
Особенности и преимущества данного изобретения станут понятными из последующего подробного описания применения изобретения со ссылкой на рисунки, приведенные ниже. Features and advantages of this invention will become apparent from the following detailed description of the application of the invention with reference to the drawings below.
На Фиг.1 изображена волновая опреснительная станция. Figure 1 shows a wave desalination station.
На Фиг.2 изображен фронтальный вид волновой опреснительной станции.
Волновая электростанция 1 содержит рабочий вал 2, энергопоглощающие элементы 3, направляющие, силовые кронштейны 5, гидроцилиндры 6, ресивер высокого давления 7, ресивер заборный 8, опреснительные секции 9, успокоители 10 и трубопровод пресной воды 11 Figure 2 shows a frontal view of a wave desalination station. Wave power plant 1 contains a working shaft 2, energy-absorbing elements 3, guides, power brackets 5, hydraulic cylinders 6, a high-pressure receiver 7, an intake receiver 8, desalination sections 9, dampers 10 and a fresh water pipeline 11
Волновая опреснительная станция работает следующим образом. Гидродинамический напор морских волн и течений, которые набегают на волновую станцию 1, воздействует на энергопоглощающие элементы 3 и создает крутящий момент относительно оси крепления направляющих 4 при подъеме волны в одном направлении, при опускании - в противоположном. Wave desalination station works as follows. The hydrodynamic head of sea waves and currents that run into the wave station 1 acts on the energy-absorbing elements 3 and creates a torque relative to the axis of attachment of the guides 4 when the wave rises in one direction, and when it descends, in the opposite direction.
Направляющие 4 соединяются шарнирными опорами с силовыми кронштейнами 5, установленными на рабочем валу 2, и гидравлическими цилиндрами двустороннего действия 6. Нагнетающие полости гидроцилиндров 6 соединены гибкими гидравлическими рукавами высокого давления с ресивером высокого давления 7. Всасывающие полости гидроцилиндров 6 соединены гибкими рукавами с заборным ресивером 8, в который вода всасывается через фильтр предварительной очистки разряжением, создаваемым поршнями гидроцилиндров, а плоскость забора воды находится ниже области распространения вредоносного цветения водорослей. The guides 4 are connected by pivot bearings with power brackets 5 mounted on the working shaft 2 and double-acting hydraulic cylinders 6. The pumping cavities of the hydraulic cylinders 6 are connected by flexible high-pressure hydraulic hoses with a high-pressure receiver 7. The suction cavities of the hydraulic cylinders 6 are connected by flexible hoses to the intake receiver 8 , into which water is sucked through a pre-filter by a vacuum created by the pistons of the hydraulic cylinders, and the plane of the water intake is below the area of distribution of harmful algae blooms.
Ресивер высокого давления 7 гидравлической трансмиссии по всей длине имеет несколько точек выхода с запорными устройствами, к которым рукавами высокого давления подсоединяются опреснительные секции 9 с держателями мембран обратного осмоса, последовательно подключающиеся (отключающиеся) по мере изменения расхода водного потока в ресивере или волновой обстановки в акватории. Опреснительные секции 9 работают эффективно, когда параметры давления и расхода водного потока лежат в требуемом диапазоне. При изменении волновой обстановки в акватории эти параметры меняются, при увеличении волн
- возрастают, при уменьшении волн - падают. Давление в ресивере высокого давления поддерживается в заданном интервале системой клапанов. Изменение расхода водного потока компенсируется изменением количества подключённых опреснительных секций 9, при этом, секции работают с максимальной производительностью. The high-pressure receiver 7 of the hydraulic transmission along the entire length has several outlet points with locking devices, to which desalination sections 9 with holders of reverse osmosis membranes are connected with high-pressure hoses, which are sequentially connected (disconnected) as the flow rate of the water flow in the receiver or the wave situation in the water area changes ... Desalination sections 9 operate efficiently when the pressure and flow rate of the water flow are within the required range. When the wave situation in the water area changes, these parameters change, with an increase in waves - increase, with decreasing waves - fall. The pressure in the high-pressure receiver is maintained at a predetermined interval by a valve system. The change in the flow rate of the water flow is compensated by the change in the number of connected desalination sections 9, while the sections operate at maximum productivity.
Пресная вода от опреснительных секций 9 гибкими рукавами подается в трубопровод пресной воды 11, по которому подается на берег за счет избыточного давления. Fresh water from the desalination sections 9 is supplied with flexible hoses to the fresh water pipeline 11, through which it is supplied to the shore due to excess pressure.
Технический регламент требует обслуживания опреснительных секций на берегу 2-3 раза в год, для этого конструкция волновой станции позволяет выполнять быструю замену секций в условиях спокойного моря . The technical regulations require maintenance of the desalination sections onshore 2-3 times a year; for this, the design of the wave station allows quick replacement of sections in calm sea conditions.
Волновая опреснительная станция работает в диапазоне волн 0,4 - 3,0 метра. При увеличении волнения станция погружается под воду в зону действия волн расчетных параметров и продолжает работать. Это позволяет получить годовой коэффициент использования установленной мощности при опреснении морской воды 0,8 The wave desalination station operates in the wavelength range of 0.4 - 3.0 meters. With an increase in waves, the station is submerged in the zone of action of waves of the design parameters and continues to operate. This makes it possible to obtain an annual coefficient of utilization of the installed capacity for desalination of seawater 0.8
Энергозатраты на существующих заводах по опреснению морской воды достигают 10 кВт на один м3 пресной воды, а себестоимость более 0,6€ за м3. Заявляемая волновая опреснительная станция позволит снизить себестоимость пресной воды до 0,3€ и использовать для опреснения только возобновляемую, экологически чистую энергию морских волн и течений.
The energy consumption at the existing seawater desalination plants reaches 10 kW per 1 m 3 of fresh water, and the cost price is more than 0.6 € per m 3 . The proposed wave desalination station will reduce the cost of fresh water to 0.3 € and use only renewable, environmentally friendly energy of sea waves and currents for desalination.
