Technical field
The present invention relates to a kind of fire safety technical field, relate in particular to a kind of for remote large-space intelligent notes nitrogen fire prevention system.
Background technology
At present, along with not only improving of science and technology, national awareness of the importance of fire prevention is also not only strengthening, be widely used in the general supporting fire extinguishing nitrogen system all of the long distance pipeline in public place (as: office building, hotel, megastore, power station etc.), it is extinguishing chemical that notes nitrogen fire extinguishing system is selected nitrogen for use, belong to clean extinguishing chemical, can not produce the pharmacology injury to human body, the no secondary disaster in fire extinguishing back.Simultaneously, can in time put out a fire to indoor filling nitrogen, their safe operation is related to the safety of people's life and property.And fire extinguishing system mostly adopts is to be raw material with the air, by the novel fire extinguishing nitrogen system that separation, storage, pipe network are laid, control is released to key link.Though some is easy to operate, during breaking out of fire, the fire extinguishing effect is very good.But, in case after the breaking out of fire, can cause in various degree loss to people's lives and properties, and these fire extinguishing systems can not reach fireproof purpose in advance.Simultaneously, be used for fire prevention system remote, large space, rare especially.What some employings were arranged is single nitrogen gas generating system, all can be equipped with a plurality of nitrogen-making devices, and in use, though the protection effect that plays is good,, can waste a lot of spaces and human and material resources like this.
As Chinese patent publication number CN 1552488 A, denomination of invention is a kind of fire prevention nitrogen supply system of supporting human breath, at least in an enclosure space, be provided with nitrogen supply (NS) pipeline and oxygen sensor, oxygen sensor is connected with oxygen control module circuit, the oxygen control module is connected with the nitrogen gas generating device circuit, nitrogen gas generating device is connected with decompressor by pipeline, decompressor is delivered in the enclosure space by pipeline, this invention has been encircleed an enclosed environment owing to carrying, and by nitrogen gas generating device and oxygen detection device to enclosed environment for nitrogen, and in the maintenance air oxygen content between 14% to 16%, because the oxygen content in the space is lower, the not burning of flame support, and 14% to 16% oxygen content can be kept human body respiration by bottom line in the air, though can effectively prevent fire like this takes place, but, using long afterwards, nitrogen gas generating device can not continue transmitting nitrogen in the enclosure space, and at a distance, the enclosure space of large space, flameproof effect is general, and installation neither be very convenient.
Summary of the invention
The purpose of this utility model exactly in order to overcome the deficiencies in the prior art, provides a kind of application wide, and cost is low, security performance is high, the remote large-space intelligent of fireproof is annotated the nitrogen fire prevention system in advance.
In order to achieve the above object, the utility model provides a kind of remote large-space intelligent to annotate the nitrogen fire prevention system, comprise nitrogen storage tank, select control valve, gas pipeline and guard plot, be provided with signal ball valve, nozzle and oxygen concentration survey meter in the described guard plot, described nitrogen storage tank one end is connected with intelligent nitrogen-making device by gas pipeline; Described nitrogen storage tank is connected in parallel to a plurality of nitrogen storage tanks by gas pipeline, and nitrogen storage tank is provided with pressure transmitter; The described nitrogen storage tank other end is parallel with a plurality of guard plots by gas pipeline through the signal ball valve.
For can be easy to maintenance to nitrogen storage tank, be respectively equipped with one on the gas pipeline at place, described nitrogen storage tank two ends and select control valve.
Easy for installation in order to safeguard intelligent nitrogen-making device, the gas pipeline that described intelligent nitrogen-making device connects the place is provided with one and selects control valve, and intelligent nitrogen-making device can be installed in different positions according to different demands.
For can be to protecting a plurality of guard plots, the installation quantity of described nitrogen storage tank be no less than one.
In order further to protect a plurality of guard plots, the quantity of described guard plot is between 1～8.
In order to gather the oxygen concentration in the guard plot in real time, the quantity of the oxygen concentration survey meter of installing in the described single guard plot is no less than one.
The beneficial effects of the utility model are: remote large-space intelligent is annotated the nitrogen fire prevention system and is adopted combination to install flexibly according to actual condition to distribute, and applied range, flameproof effect is good, cost is low, and convenient to operation, safe and reliable.
Description of drawings
Fig. 1 is the connection layout that a kind of remote large-space intelligent described in the utility model is annotated the nitrogen fire prevention system;
Among the figure: 1-intelligence nitrogen-making device, 2-select control valve, 3-gas pipeline, 4-pressure transmitter, 5-nitrogen storage tank, 6-signal ball valve, 7-guard plot, 8-nozzle, 9-oxygen concentration survey meter.
The specific embodiment
With reference to the accompanying drawings a kind of remote large-space intelligent described in the utility model being annotated the nitrogen fire prevention system is described further:
As shown in Figure 1, a kind ofly annotate the nitrogen fire prevention system for remote large-space intelligent, comprise nitrogen storage tank 5, select control valve 2, gas pipeline 3 and guard plot 7, be provided with signal ball valve 6, nozzle 8 and oxygen concentration survey meter 9 in the guard plot 7.Described oxygen concentration survey meter 9 is set with a upper lower limit value (12-16) %.Described nitrogen storage tank 5 one ends are connected with intelligent nitrogen-making device 1 by gas pipeline 3, described intelligent nitrogen-making device 1 can be installed in different positions according to different distance requirements, and nitrogen storage tank 5 is connected in parallel to a plurality of nitrogen storage tanks 5 by gas pipeline 3, and nitrogen storage tank 5 is provided with pressure transmitter 4, the nitrogen pressure value in the relevant nitrogen storage tank 5 is fed back in described pressure transmitter 4 meetings in real time, and following factually, border demand nitrogen storage tank 5 can arrange two, three, four or more; Described nitrogen storage tank 5 other ends are parallel with a plurality of guard plots 7 by gas pipeline 3 through signal ball valve 6, and the quantity of guard plot 7 can be protected a plurality of guard plots 7 between 1～8 so effectively.
