Description

Dangerous information wire communication controller

Technical field

The utility model relates to a kind of dangerous information wire communication controller.

Background technology

All have nature of dangers such as blast, inflammable, murder by poisoning, burn into radioactivity; In transportation, loading and unloading, production, use, storage, keeping process; Under certain condition, can cause burning, blast, cause the chemical substance of accidents such as personal injury and property loss, be referred to as Dangerous Chemical Substances or Hazardous Chemicals.At present common, purposes is wider have 2200 approximately surplus kind.

China State Bureau of Technical Supervision once in, nineteen ninety successively issue in 1986 " dangerous cargo article famous-brand clock " (GB6944-86) with " dangerous cargo article famous-brand clock " (GB12268-90); Dangerous goods are divided into nine big type, and have stipulated the name of an article and the numbering of dangerous cargo.

So-called inflammable and explosive chemical substance means among the standard GB 12268-90 " dangerous cargo article famous-brand clock " that with burning, blast be the inflammable and explosive chemical substance of part in pressure gas, liquid gas, flammable liquid, inflammable solid, spontaneously combustible and dangerous when wet, oxygenant and organic peroxide and poisonous substances, the corrosives of key property.At present common, purposes is wider that kind more than 1000 is arranged.The Ministry of Public Security had once issued " inflammable and explosive chemical substance fire prevention monitoring management method " (Ministry of Public Security < 1994>the 18th command) in 1994, concrete regulation has been made in the fire supervision management to the production of inflammable and explosive chemical substance, use, storage, operation, transportation in the way.

Inflammable and explosive chemical substance has bigger fire risk, in case disaster accident takes place, often harm is big, influence is big, loss is big, the difficulty etc. of putting out a fire to save life and property.

As: August in 1989, Qingdao of Shandong province Huang Island on the 12nd stock tank caused on fire from explosionly because of thunderbolt, and cofiring burnt 104 hours before and after the big fire, burnt 3.6 ten thousand tons of crude oil, burnt 5 of large oil tanks.Current big fire causes 3,540 ten thousand yuan of direct economic losses, and 14 firefighters sacrifices are arranged in big fire is puted out a fire to save life and property, and 56 people are injured; 5 oil depot workers sacrifice, and 12 people are injured.In about 4 o'clock afternoon on the 5th of March in 1998, one the 400 cubic metres ball-type gas tank bottom valves explosion of Xian City, Shanxi Province management station of Gas Company air storage tank field causes liquefied petroleum gas (LPG) to be revealed in a large number; Liquefied petroleum gas (LPG) stands in organizes the relevant personnel to carry out in the carrier leak stopping process; Because mishandling, 11 people dead (wherein firefighters 7 people) that cause on fire that blast suddenly about at 6 o'clock in afternoon, 31 injured (wherein 9 people are severely injured; 3 people death is arranged) again in the rescue process; 2 400 cubic metres of spherical tanks blasts are burnt in the tank field, and 4 the 100 cubic metres jars that crouch are scrapped, and 7 liquefied petroleum gas tank vehicles burn.

The a large amount of fact and lessons written in blood are told us, and the production, use, storage, operation, the unit of transportation, the individual that are engaged in inflammable and explosive chemical substance must establish the thought of " safety first ", grasp its characteristic and necessary fire prevention fire extinguishing knowledge.

Inflammable and explosive chemical substance has feature:

1. easy firing blast: pressure gas and the liquid gas in " inflammable and explosive chemical substance fire prevention monitoring management article famous-brand clock ", enumerated; Surpassing half is inflammable gas; The main hazard characteristic of inflammable gas is exactly inflammable and explosive; Be in the inflammable gas within the burning concentration scope, meeting ignition source can both catch fire or explode, have in addition only the atomic little energy of need with regard to inflammable-explosive.Inflammable gas is compared with flammable liquid, solid, burning more easily, and burning rate is fast, and a combustion is promptly to the greatest extent.The gas that the simple gas ratio complicated ingredient that becomes to be grouped into is formed is inflammable, combustion speed is fast, flame temperature is high, the explosion hazard that catches fire is big.The scope of the explosion limits of hydrogen, carbon monoxide, methane is respectively: 4.1% ~ 74.2%, 12.5% ~ 74%, 5.3% ~ 15%.Simultaneously, because to fill container be pressure vessel, be heated or on the scene of a fire, also be prone to take place the physical property blast during thermal radiation.

2. diffusivity: pressure gas and liquid gas so be very easy to diffusion, can spontaneously be full of any container because the intermolecular distance of gas is big, and interaction force is little.The diffusivity of gas is influenced by proportion: lighter-than-air gas can unrestrictedly spread in air, is prone to form explosive mixture with air; After the heavier-than-air gaseous diffusion, often accumulate in the face of land, irrigation canals and ditches, tunnel, factory building dead angle etc. and locate, do not loose for a long time, meet ignition source burning or blast take place.Grasp the proportion and the diffusivity thereof of gas, to instructing the fire supervision inspection, evaluation fire risk size is confirmed firebreak, selects the position of ventilating opening all to be of practical significance.

3. contractibility and swelling property: expanding with heat and contract with cold of pressure gas and liquid gas is more much bigger than liquid, solid, the breathing with gradient of temperature of its volume.Therefore container (steel cylinder) is wanted Fire Hazard Area, sun-proof, heat insulation in storage, transportation and use, when in container (steel cylinder), filling gas, note ultimate temperature pressure, and strict control fills, and prevents that overcharge, overtemperature, superpressure from causing the accident.

4. static behaviour: pressure gas and liquid gas are when the mouth of pipe or breakage spray at a high speed, because strong rubbing action can produce static.Whether charging property also is one of parameter of evaluation pressure gas and liquid gas fire risk, grasp its charging property and help in actual fire supervision inspection, to instruct the precautionary measures such as checkout facility ground connection, flow speed control to implement.

5. corrosion toxic: mainly be that some are hydrogeneous, the gas of element sulphur has corrosive attack.Can both etching apparatus like hydrogen, ammonia, sulfuretted hydrogen etc., can cause equipment crack, gas leakage when serious.To this type gas containers, take certain anti-corrosion measure, its compressive resistance of periodic inspection, make provision against emergencies.Pressure gas and liquid gas except oxygen and pressurized air, mostly have certain toxic.

6. asphyxiating: pressure gas and liquid gas all have certain asphyxiating (except oxygen and the pressurized air).Inflammable and explosive property and toxic are prone to arouse attention, and asphyxiating is often out in the cold, and especially those do not fire non-toxic gas, like inert gases such as carbon dioxide, nitrogen, helium, argons, in case leak, all can make people's death by suffocation.

7. oxidisability: the oxidisability of pressure gas and liquid gas mainly contains two kinds of situation: a kind of is clearly to classify combustion-supporting gas as, as: oxygen, pressurized air, nitrous oxide; A kind of is to classify toxic gas as, and itself does not fire, but oxidisability is very strong; With the gas that burning or blast can take place after inflammable gas mixes; Mixing with acetylene like chlorine is explosibility, and chlorine mixes with hydrogen sees the light explosibility, and fluorine gas is met hydrogen and promptly exploded; The spontaneous combustion of grease contact oxygen ability, iron also can burn in oxygen, chlorine.Therefore, in fire supervision, can not ignore the oxidisability of gas, especially classify chlorine, the fluorine gas of toxic gas as, except noting its toxic, should also be noted that its oxidisability, in storing, transport and using, will separate with other inflammable gas.

Along with the progress in epoch, the application of inflammable and explosive substances more and more widely, army, civilian inflammable and explosive substances spread all over all over the world, the self-firing and self-explosion accident is of common occurrence; It is the important difficult problem that the mankind need to be resolved hurrily that inflammable and explosive substances are implemented safe early warning.
