vel 1 expand to from . Therefore, damaging radius of level 4 expand to from . The damage effect range can endanger to m at the pressure of MPa. Under the same condition explosion effect the scope is wider. 5 結(jié) 論5 Conclusions1) When the gas pressure is bigger, the greater the explosion release energy is bigger, the damage effect range is bigger. Evaluating tank potential dangers, operation pressure shall be attention.2) Tank explosion and gas explosion shock wave overpressure are the main forms of damage effect around. But endanger area of mixture explosion and severity are more obvious. So the protective measures can effectively reduce damage effect to environment. 3) In this paper, tanks damage effects analysis is suitable for single tank, explosion source energy enhancement because of adjoining tank explosion is not considered. Damage effcte analysis based on primary explosion wave energy, did not consider possible secondary explosion and subsequent explosion. So the safe distance range is smaller. 4) When natural gas distribution station and gate station location, tank area layout, safe distance defined and range division, people should reference prediction range to selecting the safe distance range.
