Carbon dioxide initiator
Technical field
The present invention relates to demolition set technical field, particularly relate to a kind of carbon dioxide that uses as the exploitation device igniting material.
Background technology
Explosive blasting experienced by the history of thousand, adopts so far, be still one of coal mining method at present owing to not having alternative good method.Explosive blasting power is large, effect is violent, is typical naked light explosion.But naked light explosion has many defects, the aspects such as service condition, environment for use, daily management are had higher requirements.The case simultaneously because of explosive other accidental explosions occurring also happens occasionally, and also result in economic loss.
Carbon dioxide explosion utilizes liquid carbon dioxide to gasify rapidly when being heated expansion, thus the physics explosion of externally acting, do not have the toxic and harmful such as carbon monoxide and nitrogen oxygen public property to produce, improve working environment, can not naked light be produced and cause gas explosion, for gaseous mine also safety, useful manual security, health; Use carbon dioxide exploitation device to carry out orcible entry work, action time is extremely short, and in orcible entry process, the carbon dioxide of fast release has the effect of cooling, fire-retardant, explosion arrestment, is conducive to Safety of Coal Mine Production; Force of explosion is easily controlled, and by controlling the injection rate of carbon dioxide, can be easy to the force of explosion controlling the generation of carbon dioxide exploitation device.Existing carbon dioxide exploitation device, as the carbon dioxide exploitation device that application number is in the Chinese invention patent of 201310001976.6, it adopts heater and heating agent heating, heating agent is contained in paper tube, heats up after making heating agent generation chemical reaction with electric igniter energising, and gives the liquid carbon dioxide in being responsible for by paper tube wall by heat transfer, heating agent is just scrap after single use, need to fill head to unload, the heating agent of refitting heat, bothers very much; And let out can head let out can the filling seal between chamber and be provided with level pressure and let out energy sheet of passage and supervisor, when the liquid carbon dioxide gasification be responsible for expand into certain pressure, level pressure is let out and can be broken through by sheet, can rush out passage from letting out, it can sheet also be just scrap after single use that this level pressure is let out, need will to let out energy head to unload and again install on supervisor again, very time-consuming, affect production efficiency, and repeated removal, can the problems such as poorly sealed be caused.
