EPST CDER at the 7th Edition of the 2017 SAINNOV National Innovation Fair
The Renewable Energy Development Center took part in the 7th Edition of the SAINNOV National Innovation Fair which was organized by the Ministry of Industry and Mines represented by the National Institute of Industrial Property INAPI, on the occasion of the celebration of the National Day of Innovation, in Algiers on 05, 06 and 07 December 2017. The theme of this edition is "Innovation for Industrial Development".
The National Innovation Fair focuses on the latest innovations made by inventors, agencies and institutions by supporting project leaders as well as innovative companies. The INAPI for its role as an organization supporting the keys of industrial development continues its action of agent of the development of the economy and the Algerian companies and this by facilitating the recourse to the industrial property and its protection.
The EPST CDER presented at this show the innovative research products that have been patented during the year 2017.
An autonomous device for the production of biodiesel from used food oils, olive water and oilcakes using renewable energies. The integration of renewable energies will enable energy costs to be reduced by using photovoltaic solar energy for the circulation pump and agitation and the use of a renewable biogas for the heating on the other hand.
This device saves on the one hand the expenses generated by the treatment of these residues by the local authorities and on the other hand decreases the direct environmental and socio-economic nuisances caused by the accumulation of these residues. Currently, more than one hundred thousand tonnes of these residues are released into the nature, causing considerable pollution, especially in the central region of Algeria, which concentrates about 78% of oil mills in the country. At the moment, olive oil professionals have no choice but to reject this waste in the environment. However, with regard to the decree that defines the limit values for discharges of industrial liquid effluents (Decree No. 06-141 of 19 April 2006), almost all oil mills in the Center region are in violation of the law.
A renewable hydrogen torch operating on the principle of electrolysis that allows the use of hydrogen produced instantly for the cutting and welding of ferrous products.
A dust detector that can be installed in parallel with a photovoltaic station to detect the presence of dust that reduces the production of solar energy. This system can be installed directly with an automatic water jet system to clean and cool the solar panels.
A battery charge controller to monitor the battery charge level at three levels 30%, 30% to 80% and above 80%, which will be useful in stations using a large number of batteries.
An energy management system of the three sources (renewable, Sonelgaz network and generator), which gives priority to renewable energy, then switches to electricity produced by Sonelgaz, and finally, the generator.
A solar charging table for public space that allows electric charging by solar energy of electronic device. This is a new stand-alone photovoltaic system application concept used as a solar charging station to provide inexhaustible electricity after direct conversion of solar energy. The solar charging table is designed to be comfortable, and for outdoor use. It is modular and consists of a table and two benches, it is equipped with a solar generator mounted on a mat of 2m 10 high all acting as a parasol. The solar charging table is perfect for parks, gardens, cafes, restaurants, campuses, festivals, the beach, camping and other public places.
A solar dryer whose main function is to dry the waste from fruit processing plants and vegetables for reuse in the production of animal feed. This dryer can also be used to preserve fruits and vegetables for long periods of time by reducing their moisture content by solar energy.
The solar dryer is a large-scale greenhouse composed of six walls. The upper wall is made of polycarbonate inclined at the latitude of the city of Bou-Ismail (36 °). The front, right and left walls are made of polycarbonate too to let the maximum radiation pass. The inner face of the rear wall is covered with a black painted aluminum plate to ensure absorption of solar rays that pass through the polycarbonate and thus causing the greenhouse effect in the drying chamber. The back wall is thermally insulated with 5 mm thick polystyrene to minimize heat loss to the outside during the drying process. The right wall has a door allowing access to the greenhouse and the deposit of trolleys containing racks with the product to be dried.
