专注通风管道加工·排烟罩

　　When we talk about Jinan ventilation duct, we usually associate it with the ventilation duct in the office building. How much do we know about the environment of welding workshop? It's something we seldom touch. There are many vague concepts about the use of ventilation ducts. Especially in some workshop, ventilation ducts are needed. Because it is related to the health of production staff.

　　由于厂房的焊接车间一般具有焊接件大小不定、焊接地点不固定、焊接方式较多、空间高大等特色，使得污染物较难处理，室内气流组织紊乱。因而，如何经济有效的解决好焊接车间的通风除尘问题，是关系到出产工作人员身体健康的大问题。

　　Because the welding workshop of the workshop generally has the characteristics of unstable size of welding parts, unstable welding locations, more welding modes and large space, it makes the pollutants difficult to deal with and the indoor air distribution disordered. Therefore, how to solve the problem of ventilation and dust removal in welding workshop economically and effectively is a major problem related to the health of production staff.

　　通风管道是为了使空气流通，下降有害气体浓度的一种市政基础设施，首要使用在工业及建筑工程中，关于通风管道加工而言，送风办法效果的实现是关重要的。那么，常见的送风办法有哪些呢

　　Ventilation pipeline is a municipal infrastructure for air circulation and reducing the concentration of harmful gases. It is mainly used in industrial and construction projects. For the processing of ventilation pipeline, the realization of the effect of air supply method is very important. So, what are the common air supply methods?

　　榜首、工位送风工位送风是一种集区域通风、设备通风和人员自调度为一体的个性化的送风办法。在基地区域设备送风口，经过软管与地板下的送风设备相连，送风口的方位能够依据室内设备活络改变。

　　Top of the list, station air supply station air supply is a personalized air supply method which integrates regional ventilation, equipment ventilation and personnel self-regulation. In the base area, the air supply port of equipment is connected with the air supply equipment under the floor through the hose. The position of the air supply port can be changed according to the indoor equipment.

　　第二、地板送风地板送风是混合通风的另一种办法，处理后的空气经过地板下的静压箱，由送风散流器送入室内，与室内空气混合。

　　Secondly, floor air supply is another method of mixed ventilation. The treated air passes through the static pressure box under the floor and is sent into the room by the air supply diffuser to mix with the indoor air.

　　第三、置换通风置换通风归于下送风的一种，气流从坐落侧墙下部的散流器水平低速送入室内，在浮升力的效果下上升作业区，吸收人员和设备负荷构成热羽流。在上升过程中，热羽流不断卷吸周围空气，流量逐步增加。

　　Thirdly, displacement ventilation belongs to the type of downward air supply. The air flow enters the room at low speed from the diffuser located at the lower part of the side wall, and rises to the working area under the effect of buoyancy. The heat plume is formed by absorbing the load of personnel and equipment. During the rising process, the hot plume continuously sucks the surrounding air, and the flow rate gradually increases.

　　通风管道设计时要考虑到焊接是一种劳动强度比较大的工种，且在焊接工艺过程中会产生大量的有毒金属烟雾、辐射热、光污染、电焊尘、有害气体，严重影响工作人员和周边人员身体健康，因而有必要对焊接车间进行通风换气，扫除和稀释有害物，建立良好的焊接环境。

　　In the design of ventilation pipeline, it should be considered that welding is a kind of work with high labor intensity, and a large number of toxic metal fumes, radiation heat, light pollution, welding dust and harmful gases will be produced in the welding process, which seriously affects the health of staff and surrounding personnel. Therefore, it is necessary to ventilate the welding workshop, remove and dilute harmful substances, and establish a good welding. Connect to the environment.

　　在济南通风管道设计中，一方面用清洁空气，稀释室内空气物中的有害浓度，一起不断把污染空气排出室外，使室内空气中有害物浓度不超越卫生标准规则的上线允许浓度。通风通常以厂房的换气量或换气次数为基础，依据稀释理论，将车间内有害物浓度冲淡到允许浓度之下，给您的工人营造一个良好的焊接车间环境。

　　In the design of ventilation pipeline in Jinan, on the one hand, the harmful concentration in indoor air is diluted with clean air, and the polluted air is continuously discharged outdoors, so that the harmful concentration in indoor air does not exceed the permissible concentration of sanitary standard rules. Full ventilation is usually based on the ventilation rate or frequency of the workshop. According to dilution theory, the concentration of harmful substances in the workshop is diluted to the allowable concentration, so as to create a good welding workshop environment for your workers.
