氣體滅火系統(tǒng)一般由滅火劑儲(chǔ)存裝置、啟動(dòng)分配裝置、輸送釋放裝置、監(jiān)控裝置等組成。那么你知道氣體滅火系統(tǒng)的防護(hù)區(qū)要求是什么嗎？
Gas fire extinguishing system generally consists of extinguishing agent storage device, starting and distributing device, conveying and releasing device, monitoring device and so on. Do you know what the containment requirements are for a gas fire extinguishing system?
防護(hù)區(qū)宜以單個(gè)封閉空間劃分；同一區(qū)間的吊和地板下需同時(shí)保護(hù)時(shí)，可合為一個(gè)防護(hù)區(qū)；采用管網(wǎng)滅火系統(tǒng)時(shí)，一個(gè)防護(hù)區(qū)的面積不宜大于800㎡，且容積不宜大于3600m;采用預(yù)制滅火系統(tǒng)時(shí)，一個(gè)防護(hù)區(qū)的面積不宜大于500㎡，且容積不宜大于1600m。
The protected area should be divided into a single enclosed space. When the suspended ceiling layer and the floor under the same zone need to be protected at the same time, it can be combined into a protection zone; When using pipe network fire extinguishing system, the area of a protection area should not be more than 800 square meters, and the volume should not be more than 3600m; When using prefabricated fire extinguishing system, the area of a protection area should not be more than 500 square meters, and the volume should not be more than 1600m.
防護(hù)區(qū)圍護(hù)結(jié)構(gòu)及門窗的耐火極限均不宜低于0.5h；吊頂?shù)哪突饦O限不宜低于0.25h。防護(hù)區(qū)圍護(hù)結(jié)構(gòu)承受內(nèi)壓的允許壓強(qiáng)，不宜低于1200Pa。防護(hù)區(qū)應(yīng)設(shè)置泄壓口，宜設(shè)在外墻上。七氟丙烷滅火系統(tǒng)和二氧化碳?xì)怏w滅火系統(tǒng)的泄壓口應(yīng)位于防護(hù)區(qū)凈高的2/3以上。
The fire resistance limit of the enclosure structure and doors and Windows in the protection area should not be less than 0.5h; The fire resistance limit of the ceiling should not be less than 0.25h. The allowable pressure of the enclosure structure of the protection area under internal pressure should not be less than 1200Pa. The protection area should be equipped with a pressure relief port, which should be located on the outer wall. The pressure relief port of HFc-227ea fire extinguishing system and CARBON dioxide gas fire extinguishing system should be located at least 2/3 of the net height of the protected area.
噴放滅火劑前，防護(hù)區(qū)內(nèi)除泄壓口外的開口應(yīng)能自行關(guān)閉。防護(hù)區(qū)的環(huán)境溫度不應(yīng)低于-10℃。防護(hù)區(qū)用的通風(fēng)機(jī)和通風(fēng)管道中的防火閥，在噴放二氧化碳前應(yīng)自動(dòng)關(guān)閉。
Before spraying the extinguishing agent, all openings in the protected area, except the pressure relief outlet, should be closed by themselves. The ambient temperature in the zone should not be lower than -10 ° C. The fire valve in the ventilator and ventilation pipe used in the protection area should be closed automatically before spraying carbon dioxide.
采用全淹沒二氧化碳
川消滅火系統(tǒng)的防護(hù)區(qū)，應(yīng)符合下列規(guī)定：對(duì)氣體、液體、電氣火災(zāi)和固體表面火災(zāi)，在噴放二氧化碳前不能自動(dòng)關(guān)閉的開口，其面積不應(yīng)大于防護(hù)區(qū)總內(nèi)表面積的3%，且開口不應(yīng)設(shè)在底面。對(duì)固體深位火災(zāi)，除泄壓口以外的開口，在噴放二氧化碳前應(yīng)自動(dòng)關(guān)閉。等等。
For gas, liquid, electrical and solid surface fires, openings that cannot be closed automatically before carbon dioxide is discharged shall not exceed 3% of the total internal surface area of the protected area, and openings shall not be located on the underside. For solid deep fire, except for the pressure relief mouth, the opening should be automatically closed before spraying carbon dioxide. And so on.
