排烟排风管道加工怎么降低成本?

通风管道是为了使空气流通,降低有害气体浓度的一种市政基础设施。通风管,风管制作与安装所用板材、型材以及其他主要成品材料,应符合设计及相关产品标准的规定,并应用出厂检验合格证明,材料进场时应按有关标准进行验收。
Ventilation duct is a kind of municipal infrastructure to make air circulate and reduce the concentration of harmful gases. The plates, profiles and other main finished materials used for the fabrication and installation of ventilation pipes and air ducts shall comply with the provisions of the design and relevant product standards, and the factory inspection certificate shall be applied. The materials shall be accepted according to relevant standards when entering the site.
1,风管式通风:设备简单,灵活方便,易于拆卸,但由于断面小,随着管路的加长,通风阻力将增大。
1. Air duct ventilation: the equipment is simple, flexible and convenient, and easy to disassemble. However, due to the small section, the ventilation resistance will increase with the extension of the pipeline.
2,巷道式通风:适用于有平行导坑的长隧道,特点是通过前面的横通道,使正洞和平行导坑组成一个循环风流系统,在平导坑口附近安装通风机,将污浊空气由平导抽出,新鲜空气由正洞流入,形成循环风流。
2. Roadway ventilation: It is applicable to long tunnels with parallel pilot pits. It is characterized by that the main tunnel and parallel pilot pits form a circulating air flow system through the front cross passage. Ventilators are installed near the flat pilot pit mouth to extract the dirty air from the horizontal pilot, and fresh air flows in from the main tunnel to form a circulating air flow.

3,风墙式通风:利用隧道成洞部分空间,用砖砌或木板隔出一条风道,代替大直径风管,以缩短风管长度,而又能增大供风量满足通风要求,该方式适用于缩短较长,又无平行导坑可供利用,而管道式通风又难以全盘解决的情况。
3. Air wall ventilation: use part of the tunnel space to separate an air duct with bricks or boards instead of large diameter air ducts to shorten the length of the air duct, while increasing the air supply to meet the ventilation requirements. This method is applicable to the situation where the air duct is shortened for a long time, there is no parallel heading available, and pipe ventilation is difficult to solve comprehensively.
西安通风管道加工厂,加工镀锌铁皮风管(圆管、方管)、不锈钢管道(圆管、方管)。通风管道常用镀锌铁皮管道和不锈钢管道,在酸雾排气方面可进行金属管道喷塑处理再使用,也可以直接采用PP管道(防火性能不要求的情况下使用),部分小型排气、送风管道为节约成本,也可采用PVC、PPR管道作为风管。
Xi'an Ventilation Duct Processing Factory specializes in processing galvanized iron sheet air duct (round pipe, square pipe) and stainless steel pipe (round pipe, square pipe). Galvanized iron sheet pipes and stainless steel pipes are commonly used for ventilation pipes. In terms of acid mist exhaust, metal pipes can be sprayed with plastics for reuse, or PP pipes can be directly used (when the fire resistance is not required). In order to save costs, some small exhaust and air supply pipes can also use PVC and PPR pipes as air pipes.
