Describe embodiments of the present invention in detail using embodiment and accompanying drawing below, how skill is applied to the present invention whereby Art means solve technical problem, and reach the implementation process of technique effect and can fully understand and implement according to this.
Flammable liquid that the present invention is provided storage natrual danger appraisal procedure is to have more specific aim, more accurately table Harmful influence warehouse hazard property is levied, on the basis of harmful influence characteristic and amount are dangerous, with reference to harmful influence storage safe distance, is mixed Huddle put, harmful influence diffusion and the factor such as environmental condition, using analytic hierarchy process (AHP), realize that hazardous chemical is stored in a warehouse natrual danger Assess, specific implementation case is as follows：
S1：Determine warehouse：Selected certain petroleum chemical enterprise 1000m2Harmful influence warehouse, storage is all gasoline, is amounted to, 480t；
S2：Choose assessment unit i：The gasoline of warehouse storage is divided into 80 units；
S3：Physical hazard M1i, i=0,1, --- and n }, wherein n is the maximum quantity of urstoff, here n=80：Ginseng According to subordinate list 1, gasoline physical hazard is 16；
S4：Particular matter danger M2i, i=0,1, --- and n }, wherein n is the maximum quantity of urstoff：With reference to scoring Rule, the particular matter danger of gasoline is 0.2；
S5：Substance toxicity Ti=0.05, i=0,1, --- and n }, wherein n is the maximum quantity of urstoff；
S6：The amount Ki, i={ 0,1, --- n } of material, wherein n is the maximum quantity of urstoff：Each unit is 6t vapour Oil, the amount score value of material is 0.6；
S7：Material coefficient Mi=19.2, i=0,1, --- and n }, wherein n is the maximum quantity of urstoff.
S8：Taboo is apart from Ni：Because do not store taboo storage, Ni=0；
S9：Safe distance Di：Because separating distance both less than 0.5m between subregion, calculate and avoid from four direction The score value of distance, Di=0.05 is obtained after finally carrying out averagely；
S10：Storing highly Hi：Because separating storing highly both greater than 1m, its score value is 0.1；
S11：Unit natrual danger Ri=(Ni+Di+Hi+1) * (Ti+Mi) * Ki=13.28；
S12：Unit area storage capacity Ai, because unit area amount of storage is 0.48, therefore Ai=0；
S13：Channel width Q, because channel width only has 1.5m, therefore, Q=0.025；
S14：Warehouse natrual danger R=80*1.025*13.28=1089.
All above-mentioned this intellectual properties of primarily implementation, the not this new product of implementation of setting limitation other forms And/or new method.Those skilled in the art will utilize this important information, the above modification, to realize similar execution feelings Condition.But, all modifications or transformation belong to the right of reservation based on new product of the present invention.
The above, is only presently preferred embodiments of the present invention, is not the limitation for making other forms to the present invention, appoints What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc. Imitate embodiment.But it is every without departing from technical solution of the present invention content, the technical spirit according to the present invention is to above example institute Any simple modification, equivalent variations and the remodeling made, still fall within the protection domain of technical solution of the present invention.
