Ion Generator / Ionizer / Air Purifier

Origin

Ion Cluster is the aggregation of 10 ~ 60 oxygen ion molecules with lots of +ions, -ions including OH radicals. After lighting has occurred, ion clusters are created in the air, and they wrap and oxidize the bad odor molecules, germs, virus, bacteria, and many pollutants.

Toxic substances(VOC, Formaldehyde, etc) have binding energy over 6eV, so higher energy level is required to remove them. SPE H-ion cluster products emit lots of ions with energy more than 6eV, and thus has stronger decomposition effect of toxic substances compared to other ion cluster generator. This is why we call H-ion cluster (High-energy ion cluster).

SPE H-ion cluster products generate more powerful ion clusters by making barrier discharge, using quartz tube or ceramic with many discharge points and our exclusive pulse plasma technology. Ions produced by barrier discharge have much higher energy and longer life than ions produced by other methods.

Oxygen Transfer Efficiency in Water by Micro Nano Bubble

Comparison of bubble size of between the Typical Diffused-air System and Nano Fresh

Theory for Micro Nano Bubble Technology Application

Self Pressurization Effect
As the volume of liquid dissolved gas under the specified temperature is to be dissolved in proportion to the partial pressure of corresponding gas. Which demonstrates the higher solvency with the more minute bubbles, in theory the pressure inside the bubbles become infinite at the moment of extinction, As a simplified comparison, the gas solvency of 10µm bubble with diameter is approximately 20,000,000 times of 1mm diameter bubble.

Electric Potential Characteristic of Micro Nano Bubble
Smaller size bubbles demonstrate the better washing effect with higher adhesive force even in comparison with the particles of high zeta potential. Moreover, the oxygen amount per unit volume is increased enhancing the sterilization effect when the size of bubble is within the range of nano level. In other words, the minuteness of bubble size increases the washing or separation enhancing the sterilization effect accompanied with the increase of dissolved oxygen volume.

Compressive Fracture Characteristic of Micro Bubble
Compressive fracture characteristic is a well known symptom in ultrasonic engineering. Which produces the extremely high temperature of 4,000 ~ 6,000°C instantaneously with Self Pressurization Effect generated by the gas pressurizing force of surface tension residing inside the bubble and disappear after repeating the chain reactions of pressurizations and bursts within instant of 1 out 1 million second. At this moment, the generation of free radicals such OH & etc., decomposes the bacteria and harmful chemical substances residing inside water.

Adhesion Characteristic of Micro Bubble
The smaller sized bubbles provide the ease of infiltration allowing the adhesion with particles against the high electric potential. At the moment, the cleaning process becomes effective as the relative gravity of particles is decreased once the particles and bubbles are adhered together.

Wind Turbine Generator

Introduction

The wind power plant is a product of development, which is based on 20 years of constant experience in wind turbine design and production. It is designed by using well-tested and dependable construction elements in combination with modern technical know-how, to arrive the best possible results transferring wind into electrical energy.

Utilizing the same reliable, rugged construction of the past along with all updates in the technology, this turbine is designed for an environment as seen in wind farms with high wind speeds, thus ensuring maximum production and output. The optimal availability and production capacity together with the high manufacturing quality from the production line, along with a favorable price/efficiency relationship makes the turbine to be short-term economical investment.

Certified Wind Technology

Blade / Rotor
- The DW 250 is equipped with a 3-blade up wind stall regulated rotor, with an improved overall efficiency. A special placing on the frame reduces the effect of moments of rotation. The blades are made of reinforced polyester and are equipped with "fail-safe" tip-brakes, which are activated simultaneously by centrifugal forces. The projected area of the blades is relative small, which contributes to a high survival wind speed. With a blade length of 13,4 m and a diameter of 29 m the rotor of the DW 250 has a swept area of 661 m2. The rotor speed is 40 rpm.Nacelle
- The hot dip galvanized nacelle frame is constructed of welded steel beams that support the main shaft, gear, generator etc. The yaw ring is fitted to the bottom of the frame and allows the connection to the tower. The nacelle can be reached by a ladder inside the tower. The cover is made of galvanized sheets of steel.Gearbox
- A heavy three-stage helical gear transforms the 40 revolutions of the rotor to the 1211-rpm of the generator. This gear is specially designed for the DW 250 with a gear ratio of 1 : 30.23. An oil cooler is separately placed.Hub
- The hub is made of casted steel GGG 40.3 and mounted to the rotor shaft-flange. Correction of the pitch angel of the blades is possible by oval holes in the blade flanges.Main shaft
- The main shaft is a forged piece and made of high-grade alloyed steel. It is mounted in two bearings, able to transfer all forces and moments to frame and gear.Main bearings
- Two long-time grease lubricated bearings are the basis for a nearly noiseless operation of the main shaft. The places the main bearings are fitted to the frame are machined.Coupling
- The power of the rotor, transformed in the gearbox, is transmitted to the generator by an elastic coupling. With this method no vibrations will reach the bearings of the generator, and a longer lifetime is expected.Brakes and emergency brake system
- The turbine is equipped with two (2) independent fail-safe systems. As mentioned before, the blades are equipped with a simultaneously activated safety tip-brake, and on top of these blades braking mechanisms, the WTG is equipped with a disc brake. The disc braking mechanism is supplied through two hydraulic fail-safe brake callipers, which are activated through a loss of supply (grid) voltage. The tip-brakes are in normal operation hold in position by a hydraulic cylinder. In emergency situations a hydraulic valve is activated by centrifugal forces, and both brake systems are engaged, independent of each other.

Secure Wind Technology

Tower
- The lattice tower is a new design especially made to reach all destinations around the world by low costs. All parts of the turbine are suitable in a 40ft container. It has a height of 46m so that the rotor of the turbine is reaching a lower turbulence area. This will increase the output and the service life of the WTG. The microprocessor control system is placed at the bottom of the tower in a special housing. A lockable door prevents unauthorized access. The WTG comes equipped with safety belt and safety line, which provides a safety climbing while installation and maintenance.Control panel
- All functions of the wind turbine are controlled by means of a proven microprocessor. While the turbine is operating and connected to the grid, the computer stores a number of operational data. If the WTG is erected in a wind farm, the turbines can be linked up to a computer management system. This design makes it possible to retrieve data and actual performance date from the wind turbines, and allows remote operation of the machines. If no management system is utilized, the same data can be read on the display mounted on the computer, that is continuously checking all sensors and the safety system:
- Grid control of: Voltage, Frequency, Phase equality
- Over speed control on rotor that activates disc brake
- Thermal sensor in generator
- Vibration sensor
- Automatic untwisting of cables
- Thermal relay for yaw gear motor
- Automatic stop for worn brake pads
- Automatic start-up in the event of grid failure
- Self-diagnostic in case of failure
- Display indicates failure code.
- Generator speed
- Rotor speed
- Yawing
- Over speedGenerator
- The generator is a pole-changing asynchronous machine with a nominal output of 250 kW at 1211 rpm respectively 50 kW at 910 rpm. It is operating on 380V AC level. A ventilator is cooling the outside of the machine.

Yaw-System
- The yaw-system is representing the main advantage in modern wind technology and makes the DW 250 superior, compared with other conventional engineering in the wind industry. The taken solution, designed and well tested, is to arrange two gears in that way, that any space in the system is eliminated. These yaw gear system incorporate both, a damping system to decrease forces induced by the turning forces of the rotor, and a brake system, while the yaw motors are stopped. This system is ideally suited for WTG's installed in multiples (wind farm applications) where the shadow effect of upwind placed WTG's is blame for exposures to dynamic turning loads. Another features of this yaw system are the automatic untwisting of the cables, and an additional twisted cable switch for more safety.
