Technical field
The utility model relates to the big pressure tank real time monitoring apparatus of a kind of low pressure CO 2, refers in particular to the pressure state real time monitoring apparatus of fire-fighting fire extinguishing with big jar of equipment of low pressure CO 2.
Background technology
At present, many public and production places all exist fire safety evaluating hidden danger, as all kinds of large-scale oil depots, combustible and explosive articles warehouse and hazardous chemical warehouse etc.Whether the fireproofing installation in these places puts in place, and direct relation the people's safety of life and property, in case breaking out of fire will cause immeasurable loss.Therefore they are society and enterprise fireproof key area.
CO is one of system that developing history is the longest, fire-fighting technique is the most ripe in the current gas extinguishing system, and at western developed country, carbon dioxide installing amount is only second to sprinkler system, become gas extinguishing system.Some important places all are provided with big jar of self-extinguishing equipment of low pressure CO 2 of external full import usually at home; in case when having fire to take place; automatic fire extinguisher will continuously eject carbon dioxide to fire position puts out a fire; so just can be in the very first time; stop the diffusion of the intensity of a fire most effectively; the fire that is in the budding period is put out rapidly, protected people's safety of life and property.Because the tank body of big jar of fire-protection equipment of this low pressure CO 2 is a kind of pressure vessel; running by refrigeration unit on the equipment is limited to the pressure of carbon dioxide about 2MPa; making it become normal liquid form is stored in the tank body; according to the size in flame failure protection zone, the low pressure CO 2 in the tank body generally all can be more than several tons even tens tons.So this big jar very relies on refrigeration unit, in case fault has appearred in refrigeration unit, normal refrigerating operaton, the temperature of the liquid carbon dioxide in the tank body will raise, and pressure also can rise thereupon, if nobody in time finds and head it off, and big jar pressure-release valve is malfunctioning or can not fast pressure relief, will produce very serious consequence this moment, can blast because of the carbon dioxide that sharply expands in inside, cause huge casualties and property loss for big jar.Therefore, the big jar pressure of low pressure CO 2 is carried out real-time monitoring system and seem particularly important.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of low pressure CO 2 big pressure tank real time monitoring apparatus, when there is potential safety hazard in big pressure tank rising, in time the relevant administration of the prevention and control personnel of notice make them adopt remedial measures in the very first time and fix a breakdown.
The utility model takes following technical measures to solve the problems of the technologies described above:
The big pressure tank real time monitoring apparatus of a kind of low pressure CO 2, it is characterized in that: comprise tank body pressure monitor module, control module, audible-visual annunciator and information transfer module, described tank body pressure monitor module comprises electro connecting pressure gauge and the pressure signal delivery outlet that is electrically connected with electro connecting pressure gauge;
Control module and pressure signal delivery outlet are electrically connected; The output terminal of control module is electrically connected with audible-visual annunciator and information transfer module respectively.
The described information transfer system comprises note processing unit and note transmitting element.
Further, described note processing unit is automatic SMS generator, and described note transmitting element adopts on the GSM mobile handset network phone number that note is extremely default.
Further again, described automatic SMS generator adopts the JB35G-A type SMS module based on gsm system.
As preferably, described electro connecting pressure gauge is connected on the pipeline that is connected with tank body.
Adopt the beneficial effect of technique scheme to be; if in case big tank internal pressure surpasses warning value; system will detect and send at the scene sound and light alarm immediately; simultaneously pressure superelevation signal is sent to relevant administration of the prevention and control personnel by mobile phone short messages; they just can know at once that the big pressure tank of low pressure CO 2 is too high; problem has appearred in big jar of refrigeration aspect; so just can be allowed to condition at the very first time reacts; get rid of the refrigeration machine fault in the shortest time; so that the pressure of carbon dioxide remains within the safe scope in big jar; protected on the one hand the safety of equipment, can also prevent loss economically that the release because of carbon dioxide causes on the other hand and the pollution of ecologic environment is destroyed.
The utility model cost is a kind of both economical and reliable fire-fighting remote information monitoring system about 900 yuans.Its applicability is strong, can be arranged at multiple public place and production place, and range of application is very extensive, very suitable the popularization.
