BIC has developed a new type of Melting & Deicing device (MDD). MDD is installed horizontally between and 1m below the water surface, using high-performance air-entraining technology to form micro-nano aerated water flow, pushing the bottom water body and surface water body to move forward quickly.
Melting & Deicing device from BIC exchanges heat with the stratum water body and disturbs the water body in front of the sluice, so that the water body cannot form an ice core. Even in the severe cold winter, it will not form an ice layer, which effectively solves the frozen problem before the sluice. For the detaield melting and deicing solution, welcome to contact us!
The structure of the device mainly includes high performance motor, integral stainless steel submersible anti-ice erosion shell, conveying cylinder, air storage chamber, bleed tube, impeller, water delivery bucket, bracket, cover net and other components. At the same time, MDD is equipped with a propeller blade, which stirs with water while the equipment sucks in the air, so that the water is quickly spread.
The high-performance motor quickly mixes the compressed air in the air intake pipe and air storage chamber with the water body. Finally, the high-speed rotating impeller produces strong axial thrust and radial stirring, which crushes the compressed air in the water body to form tiny particles. Nano bubbles are oriented horizontally and pushed out into the water body through the conveying cylinder. The flow of micro-nano bubbles impacts, stirs, and pushes the water flow out to fan-shaped radiation. The accelerated bubbles diffuse and mix into the body water, making the water molecules less likely to condense in cold temperatures.
Wide Ice Breaking Range
Each device can control water surface width of more than 20m, so that no ice cover is formed within the river length of nearly 5m. The powerful water flow can push the water flow to push the air bearing water body beyond 30m.
MDD extracts relatively high temperature water in the middle and lower part of the river, which increases the temperature of the surface water. By pumping gas, the existence of ice nuclei in the water body can be effectively reduced, so that freeze in the water can be avoided as much as possible. Studies have shown that piping hot milk freezes before cold milk. This effect called the Mpemba effect. The reason for the Mpemba effect is that the hot milk contains less air. At the same time, the horizontal jet generated by MDD makes the surface water body strongly turbulent, which can reduce the formation of ice blossoms.
Compact Structure, High Inflation Rate, Fast Ice Melting Rate
When MDD is running in the water, it can not only increase the dissolved oxygen to the greatest extent, but also push the water flow to fully exchange the bottom water and the surface water and expand the exchange water body forward. In the process of the water exchange, the micro-nano bubbles produced by device stay in the water for a long time and are constantly disturbed in the water. MDD can suck in air at a rate of up to 22,500 cubic meters per hour, which ensures an efficient inflation rate and ice melting rate.
Safe and Reliable, Energy Saving and Environmental Protection, No Secondary Pollution To The Water Body
Since the air contains 21% oxygen, plus a large number of anions and cations generated when micro-nano bubbles burst in the water body, MDD can make the water body clear in a short period of time. So as to achieve the function of water purification. MDD combines the pressure water jet method and the compressing air blowing method at the technical level, which increases the equipment efficiency and reduces the energy consumption. Generally, the power of a piece of equipment is below 3kW.
Simple Construction, Convenient Operation And Maintenance
The installation of MDD is convenient and concise, requiring only 5 installation workers with high water quality and 1 high-voltage electrician, and 1 manned vessel. In order to prevent large-scale collisions in the water from damaging the equipment, it is only necessary to remove the equipment for maintenance during the flood season and put it back in place after the flood season. In the case of not involving flood control during the flood season, the equipment can always be placed underwater. Daily maintenance only needs to check whether the cable is damaged, whether the motor grille is deformed, and whether the motor is running normally. Later operation and maintenance is convenient, saving money and effort.
Wide Range of Applications
In winter of high latitudes, rivers, channels will freeze, forming water ice, floating ice and ice caps. Ice conditions often change continuously with changes in temperature, the changing of ice conditions will significantly change the movement of water currents. If it is not properly controlled, it may cause some hydraulic structures, such as gates, steel dams, rubber dams, etc. To be damaged by ice erosion.
