专注通风管道加工·排烟罩

　　The air environment of the workshop is improved by ventilation. On the one hand, the turbid air that does not conform to the hygienic standard is discharged to the outdoor in some address or the whole workshop. On the other hand, fresh air is sent to the indoor air by purifying the air which is in accordance with the hygienic requirements. We call the former the exhaust, and the latter is called the air intake.

　　
      部分排风体系由以下几部分组成：

　　Part of the exhaust system consists of the following parts:

　　（1）部分排风罩

　　部分排风罩是用来捕集有害物的。它的功能对部分排风体系的技能经济指标有直接影响。功能杰出的部分排风罩，如密闭罩，只需较小的风量就可以取得杰出的作业效果。因为出产设备和操作的不同，排风罩的方式是多种多样的。

　　(1) partial exhaust hood

　　Part of the exhaust hood is used to capture harmful things. Its function has a direct impact on the technical and economic indicators of some exhaust systems. Part of the exhaust hood with outstanding function, such as a closed hood, can achieve excellent results only with a smaller air volume. Because of the difference in production equipment and operation, the exhaust hood is varied.

　　（2）风管

　　通风体系中运送气体的管道称为风管，它把体系中的各种设备或部件连成了一个全体。为了进步体系的经济性，应合理选定风管中的气体流速，管路应力求短、直。风管通常用外表润滑的资料制造，如：薄钢板、聚氯乙烯板，有时也用混凝土、砖等资料。

　　(2) wind pipe

　　A pipe conveying gas in a ventilation system is called an air duct, which connects all kinds of equipment or components in the system. In order to improve the economy of the system, the gas velocity in the duct should be selected reasonably, and the pipeline should be short and straight. Wind pipes are usually made of external lubrication data, such as thin steel plates, PVC plates, and sometimes concrete, brick and other materials.

　　（3）除尘、净化设备

　　为了避免大气污染，当排出空气中有害物量超越排放标准时，必须用净化设备处理，达到排放标准后，排人大气。净化设备分除尘器和有害气体净化设备两类。

　　(3) dust removal and purification equipment

　　In order to avoid air pollution, when the amount of harmful substances discharged from the air exceeds the discharge standard, we must use the purification equipment to deal with it. Cleaning equipment is divided into two categories: dust collector and harmful gas purification equipment.

　　（4）风机

　　风机向机械排风体系捉供空气活动的动力。为了避免风机的磨损和腐蚀，通常把它放在净化设备的后边。

　　(4) fan

　　The power of the fan to catch the air activity to the mechanical exhaust system. In order to avoid wear and corrosion of fans, it is usually placed behind the purification equipment.

　　假如只对部分地址进行排风或送风，即部分通风；假如对整个车间进行排风或送风，则为通风。通常，按通风体系的效果规模不同，可将通风分为部分通风、通风和事端通风。部分通风体系又分为部分进风和部分排风两大类，它们都是使用部分气流，使部分作业地址不受有害物的污染，形成杰出的空气环境。

　　If only part of the address is draught or air supply, that is part of ventilation; if the whole workshop ventilation or air supply, it is a comprehensive ventilation. In general, ventilation can be divided into partial ventilation, full ventilation and event ventilation according to the scale of ventilation system. Part of the ventilation system is divided into two types of air intake and partial air exhaust. They all use part of the air flow to make the address of part of the work not polluted by harmful substances, forming an outstanding air environment.
