Today, Jinan's small ventilation series tells everyone how to ventilate.

　　清潔通風(fēng)

　　Clean and ventilate

　　這種方法更容易理解，也就是說，當(dāng)項(xiàng)目的外部空氣沒有被有毒有害物質(zhì)污染時(shí)，系統(tǒng)就會(huì)運(yùn)行。

　　This method is easier to understand, that is, when the external air of the project is not polluted by toxic and harmful substances, the system will run.

　　隔離通風(fēng)

　　Isolation ventilation

　　所謂隔離通風(fēng)是指在工程隔離保護(hù)過程中實(shí)現(xiàn)內(nèi)部循環(huán)通風(fēng)的通風(fēng)系統(tǒng)的運(yùn)行方式。 隔離保護(hù)是一種民防工程保護(hù)方法，利用工程本身的防護(hù)能力和氣密性，防止有毒有害物質(zhì)的空氣侵入工程中，危害工程人員的。

　　The so-called isolated ventilation refers to the operation mode of the ventilation system to achieve internal circulation ventilation in the process of Engineering isolation and protection. Isolation protection is a kind of civil defense engineering protection method, which uses the protection ability and air tightness of the project itself to prevent the air of toxic and harmful substances from invading the project and endangering the safety of engineering personnel.

　　出現(xiàn)以下任一情況時(shí)，該項(xiàng)目將轉(zhuǎn)移到隔離保護(hù)中：

　　The project will be transferred to isolation protection in case of any of the following conditions:

　　敵人對(duì)地面或襲擊初期的核生化武器襲擊的警告；

　　Warning of the enemy's attack on the ground or on nuclear, chemical or biological weapons at the beginning of the attack;

　　當(dāng)項(xiàng)目外發(fā)生大面積火災(zāi)時(shí);

　　In case of large area fire outside the project;

　　在暴露于外部空氣的情況下，當(dāng)過濾設(shè)備發(fā)生故障時(shí)；

　　In case of exposure to external air, in case of filter equipment failure;

　　通風(fēng)孔被堵塞，通風(fēng)已損壞。

　　The vent is blocked and damaged.

　　通風(fēng)設(shè)備

　　Ventilation equipment price

　　過濾器通風(fēng)（也稱為過濾器通風(fēng)）

　　Filter ventilation (also known as filter ventilation)

　　所謂的過濾通風(fēng)，是指工程外部的空氣被有毒有害物質(zhì)污染，引入工程的空氣必須經(jīng)過除塵處理后再分配到工程內(nèi)部，用過的空氣必須排出。 通過超壓排氣系統(tǒng)。 項(xiàng)目的通風(fēng)方式。

　　The so-called filtering ventilation refers to the air outside the project is polluted by toxic and harmful substances. The air introduced into the project must be dedusted and then distributed to the project interior, and the used air must be discharged. Through the overpressure exhaust system. Ventilation mode of the project.

　　當(dāng)出現(xiàn)以下任何一種情況時(shí)，項(xiàng)目將轉(zhuǎn)移到過濾器通風(fēng)系統(tǒng)中：

　　? items will be transferred to the filter ventilation system when any of the following occurs:

　　當(dāng)項(xiàng)目需要形成一定的超壓值時(shí)，一些人員急需進(jìn)入和退出項(xiàng)目；

　　When the project needs to form a certain overpressure value, some personnel urgently need to enter and exit the project;

　　當(dāng)毒物沿著縫隙進(jìn)入項(xiàng)目時(shí)，將威脅到項(xiàng)目內(nèi)部人員的；

　　When poison enters the project along the gap, it will threaten the safety of personnel inside the project;

　　當(dāng)項(xiàng)目隔離一段時(shí)間后，空氣中的CO2濃度會(huì)上升到規(guī)定的標(biāo)準(zhǔn)，并且人員難以維持。

　　When the project is isolated for a period of time, the CO2 concentration in the air will rise to the specified standard, and it is difficult for personnel to maintain.
