通风管道的选材与排风
选择好的通风材料,首先在风管制作过程中,要注意风管的表面是铝箔材质,为了确保表面层不易损坏,因此要对铝箔材质作出规定,并且为了保证安全也规定了风管表层的铝箔厚度。其次,对于薄钢板法兰通风管道内、外表层和内部绝热材料粘接牢固,这是是保证复合材料安全的基本条件之一。按照规定面积和厚度不仅能延长风管的使用寿命还能增加保温效果,让风管得到最大程度和最好的利用。
Select the good ventilation material, first in the production process of the wind pipe, we should pay attention to the surface of the wind pipe is aluminum foil material. In order to ensure that the surface layer is not easy to damage, therefore, the material of aluminum foil should be stipulated, and the thickness of the aluminum foil on the surface of the pipe is also stipulated to ensure safety. Secondly, it is one of the basic conditions to ensure the safety of composite materials for bonding the inner, outer and inner insulation of thin steel flange ventilation pipes. According to the specified area and thickness, not only can prolong the service life of the wind pipe, but also increase the insulation effect, so that the wind pipe can be maximally and best utilized.

通风管道的局部排风
Local exhaust ventilation of a ventilated pipe

用通风方法改善车间的空气环境,一方面在局部地点或整个车间把不符合卫生标准的污浊空气排至室外,另一方面,把新鲜空气或经过净化符合卫生要求的空气送入室内。我们把前者称为排风,把后者称为进风。
Ventilation is used to improve the air environment in the workshop. On the one hand, the dirty air, which does not meet the hygienic standard, is discharged to the outdoor in the local or the whole workshop. On the other hand, fresh air is sent to the indoor air which is in accordance with the hygienic requirements. We call the former the exhaust, and the latter is called the air intake.

在集中产生有害物的局部地点,设置捕集装置,将有害物排走,以控制有害物向室内扩散,这种通风方法称为局部排风。这是防毒,排尘最有效的通风方法。
In the local place where the harmful substances are concentrated, the trap device is set up to remove the harmful substances to control the diffusion of harmful substances to the interior. This ventilation method is called the local exhaust. This is the most effective ventilation method for antivirus and dust removal.

通风管道
Ventilating pipe

局部排风系统由以下几部分组成:
The local air exhausting system is composed of the following parts:

(1)除尘、净化设备
(1) dust removal and purification equipment

为了防止大气污染,当排出空气中有害物量超过排放标准时,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装置两类。
In order to prevent air pollution, when the amount of harmful substances discharged from the air exceeds the discharge standard, it must be treated with purification equipment. Cleaning equipment is divided into two categories: dust collector and harmful gas purification device.

(2)风机
(2) fan

风机向机械排风系统捉供空气流动的动力。为了防止风机的磨损和腐蚀,通常把它放在净化设备的后面。
The power of the fan to catch the air flow to the mechanical exhaust system. In order to prevent fan wear and corrosion, it is usually placed behind the purification equipment.

如果只对局部地点进行排风或送风,即局部通风;如果对整个车间进行排风或送风,则为全面通风。通常,按通风系统的作用范围不同,可将通风分为局部通风、全面通风和事故通风。局部通风系统又分为局部进风和局部排风两大类,它们都是利用局部气流,使局部工作地点不受有害物的污染,造成良好的空气环境。
If only partial ventilation or air supply is applied to local locations, local ventilation is provided; if ventilation or air supply is carried out in the whole workshop, the ventilation is complete. Generally, ventilation can be divided into local ventilation, comprehensive ventilation and accident ventilation according to the different scope of ventilation system. The local ventilation system is divided into two types of local air intake and local air exhaust. They all use local air to make the local working place not polluted by harmful things and cause a good air environment.

(3)局部排风罩
(3) local exhaust hood

局部排风罩是用来捕集有害物的。它的性能对局部排风系统的技术经济指标有直接影响。性能良好的局部排风罩,如密闭罩,只要较小的风量就可以获得良好的工作效果。由于生产设备和操作的不同,排风罩的形式是多种多样的。
The local exhaust hood is used to capture harmful substances. Its performance has a direct impact on the technical and economic indexes of the local exhaust system. The local exhaust hood with good performance, such as a closed hood, can achieve good results with a smaller air volume. Because of the difference in production equipment and operation, the form of exhaust hood is varied.
