The history-making earthquake and tsunami have caused the most serious nuclear accidents in Japan's Fukushima Daiichi nuclear plants ' our planet's most devastating nuclear disaster since Chernobyl and Three Mile Island. The first massive explosion and leak happened on March 12, 2011 at the Fukushima Daiichi atomic power plant. Despite all immediate efforts to cool along the reactors, reactor No.3 and three other reactors lost its ability to chill on Sunday. The fact results in three massive hydrogen explosions in Fukushima Daiichi nuclear plant, which sends enormous column of smoke in the air. An estimated of greater than 180,000 individuals have evacuated. More dangerously, the radioactive leakage has raised rays levels across the plant higher than the safety limit. 160 folks are being exposed to radiation.
The filter adopts high - strength wedge-shaped strainer to control the automatic cleaning of filter element through pressure differential control. When the impurity accumulates in the filter surface causes the import and export pressure difference to increase to the set value, or the timer reaches the preset time, the electric control box sends out the signal to drive the anti-flushing mechanism. When backwash suction dish and filter imports are pair, the drain valve is opened, the system pressure drainage, chuck and filter the inside a relative pressure below the filter of the lateral pressure of negative pressure zone, forcing some net circulating water from the inside filter lateral flow filter, adsorption on the inner wall of the filter in the impurity particles with flow into ç©£ disc and is discharged from the drain valve. The specially designed filter causes the inside of the filter to produce a jet effect, and any impurities will be washed away from the smooth inner wall. When the pressure difference of the filter is returned to normal or the timer set time is finished, the material does not break the flow during the whole process, and the anti-washing water consumption is low, which realizes the continuous and automatic production
Sometime in the late 19th century, a forgotten mechanic fastened a primitive engine with a horse drawn wagon creating the initial horseless wagon. The details happen to be lost to history but from that humble beginning, a method of automobile came to be, one that still exercises influence upon us over century later.
