Abstract
The invention relates to a nonmetal block explosion suppression sphere which comprises two detachably-combined explosion suppression semispheres, wherein the detachably-combined explosion suppression semispheres are hollow semispherical ball casings; positioning holes are formed in the end parts of the explosion suppression semispheres; and at least one window hole is formed in each explosion suppression semisphere. The nonmetal block explosion suppression sphere disclosed by the invention has excellent explosion suppression pressure drop and excellent performance of suppressing the spreading speed of flame. After a nonmetal spherical explosion suppression material is filled, the explosion suppression pressure drop is 70-85 percent and the suppression for the spreading speed of the flame can be reduced to 18-1.0M/S (when no explosion suppression material is filled, the suppression for the spreading speed of the flame is 190-80 M/S); in the processes of transporting, filling and using, a support structure is not required and the stacking height is not limited; and the nonmetal explosion suppression sphere can be automatically filled and taken for cleaning and is high in mounting and maintaining efficiency and low in cost.
Description
Technical field
The present invention relates to the explosion-suppressing material technical fields of inflammable and explosive liquid (gas) body in production, transportation, storage and use procedure such as gasoline, diesel oil, kerosene, aero oil, liquefied gas, natural gas, propane, relate in particular to the datonation-inhibition ball of a kind of nonmetal obstruct.
Background technology
As everyone knows, inflammable and explosive liquid (gas) bodies such as gasoline, diesel oil, kerosene, aero oil, liquefied gas, natural gas, propane are in production, transportation, storage and use procedure, owing to safety measure improper or unexpected cause the burning and explosion accident, often cause great property loss and casualties.Therefore various countries research and develop explosion-suppressing material and product in succession, improve the safety issue of inflammable and explosive liquid (gas) body in production, use and storage and transport process, the fire explosion of the chemicals that prevents from endangering.
The present domestic metal explosion-suppressing material that uses mostly is aluminium alloy and magnesium alloy, and product is network structure, can be rolled into cylindricality, sphere etc.The netted explosion-suppressing material of aluminium alloy and magnesium alloy all has similar datonation-inhibition function, the datonation-inhibition pressure range of decrease behind the filling explosion-suppressing material is between 56～60%, be 190～80M/S) in the time of can being down to 23～16M/S(without the filling explosion-suppressing material to the inhibition of flame propagation velocity, explosion-suppressing material is 1.2～1.7% in the volume of a container occupation rate.But the wire netting explosion-suppressing material has the following disadvantages:
(1) the datonation-inhibition pressure range of decrease, the rejection of flame propagation velocity is difficult to improve;
(2) transportation and use procedure need supporting construction, stack highly to be restricted;
(3) filling explosion-suppressing material needs manually-operated, and needs auxiliary support frame;
(4) clean difficulty behind the fouling of use procedure wire netting or the obstruction mesh;
(5) will prevent pressing with stacking when storing in the production process, otherwise the easy deformation of mesh affects datonation-inhibition function and explosion-suppressing material volume occupation rate;
(6) difficult for the filling ratio in little space;
(7) for filling and the use of oil storage tank or oil pipeline, oxidation with aging after will become fragile, form fragment, the chip that can drop when being subject to vibrating pollutes or pipeline road is resulted in blockage oil product.
(8) the netted explosion-suppressing material of aluminium alloy and almag is yielding under flame pressure, affects datonation-inhibition function.
Summary of the invention
The technical problem to be solved in the present invention is: for solve existing explosion-suppressing material datonation-inhibition function not high, stack highly to be restricted, to stop up and clean difficulty, the easy deformation of mesh behind the mesh, affect the problems such as datonation-inhibition function and explosion-suppressing material volume occupation rate, the invention provides the datonation-inhibition ball of a kind of nonmetal obstruct, adopt the datonation-inhibition structure of hollow out spheroid to solve the problems referred to above.
The technical solution adopted for the present invention to solve the technical problems is: the datonation-inhibition ball of a kind of nonmetal obstruct, the datonation-inhibition hemisphere that comprises two detachable combinations, described datonation-inhibition hemisphere is hollow hemisphere spherical shell, and described datonation-inhibition hemisphere end has locating hole, has at least one fenestra on the described datonation-inhibition hemisphere.
