专注通风管道加工·排烟罩

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

　　清洁通风

　　Clean and ventilate

　　这种方法更容易理解，也就是说，当项目的外部空气没有被有毒有害物质污染时，系统就会运行。

　　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.

　　隔离通风

　　Isolation ventilation

　　所谓隔离通风是指在工程隔离保护过程中实现内部循环通风的通风系统的运行方式。 隔离保护是一种民防工程保护方法，利用工程本身的防护能力和气密性，防止有毒有害物质的空气侵入工程中，危害工程人员的。

　　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.

　　出现以下任一情况时，该项目将转移到隔离保护中：

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

　　敌人对地面或袭击初期的核生化武器袭击的警告；

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

　　当项目外发生大面积火灾时;

　　In case of large area fire outside the project;

　　在暴露于外部空气的情况下，当过滤设备发生故障时；

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

　　通风孔被堵塞，通风已损坏。

　　The vent is blocked and damaged.

　　通风设备

　　Ventilation equipment price

　　过滤器通风（也称为过滤器通风）

　　Filter ventilation (also known as filter ventilation)

　　所谓的过滤通风，是指工程外部的空气被有毒有害物质污染，引入工程的空气必须经过除尘处理后再分配到工程内部，用过的空气必须排出。 通过超压排气系统。 项目的通风方式。

　　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.

　　当出现以下任何一种情况时，项目将转移到过滤器通风系统中：

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

　　当项目需要形成一定的超压值时，一些人员急需进入和退出项目；

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

　　当毒物沿着缝隙进入项目时，将威胁到项目内部人员的；

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

　　当项目隔离一段时间后，空气中的CO2浓度会上升到规定的标准，并且人员难以维持。

　　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.
