          工业通风管道设计常见方式
          Common ways of industrial ventilation duct design
          随着社会工业化的深入发展,工业类通风管道设计也存在着诸多类别,不同的生产情况,对作业环境需求也各不相同。例如:化工类作业,由于此类作业过程中很容易产生带有害因子的气体,因此通风管道常以净化空气等需求为主;而电子类作业,则以调温控湿为主。结合其作用的范围、有无动力系统等,可划分为以下五种方式。
          With the further development of social industrialization, there are many types of industrial ventilation duct design. Different production conditions have different demands on the working environment. For example, for chemical operations, since it is easy to produce gases with harmful factors in the process of such operations, the ventilation pipes are often mainly required to purify air; Electronic work is mainly temperature and humidity control. It can be divided into the following five modes according to the scope of its function and the presence or absence of power system.
          (1)全面通风。全面通风,细分为稀释、单向流通、均匀流通、置换四种方式。旨在对工业区域的整体面积进行空气流通或置换,将整个空间面积中危害因素较小、浓度较低,或是多余的湿气、热气等稀释、排除至卫生标准限值之下,确??掌慕嗑欢?。
          (1) Full ventilation. Comprehensive ventilation is divided into dilution, one-way flow, uniform flow and replacement. The purpose is to conduct air circulation or replacement on the whole area of the industrial area, dilute and exclude the small hazard factors, low concentration, or excess moisture, hot gas, etc. in the whole space area to the limit value of the health standard, and ensure the cleanliness of the air.
          (2)局部通风。局部通风,又分为两种:局部送风、局部排风。主要是利用局部的空气流通,达到净化空气,降低危害因素带来不良影响的目的。
          (2) Local ventilation. Local ventilation is divided into two types: local air supply and local exhaust. It is mainly to use local air circulation to purify the air and reduce the adverse effects caused by hazardous factors.
          (3)机械通风。通过动力系统,凭借风机引起的气压,促使空气流通与置换。常见于化工类工业,能够将室内有毒有害污染物从机械通风管道迅速排出到指定处理区域进行分解净化。
          (3) Mechanical ventilation. Through the power system, the air circulation and replacement are promoted by the air pressure caused by the fan. Commonly used in chemical industry, it can quickly discharge indoor toxic and harmful pollutants from the mechanical ventilation pipe to the designated treatment area for decomposition and purification.
          (4)自然通风。自然通风,顾名思义是一种凭借室外风力形成的风压,以及室内外空气温差所引起的热压下的空气流通,是以自然因素为依托的无动力通风方式。因自然因素存在不稳定性,故被工业单独采用的情况较少,常与其他方式结合来使用。
          (4) Natural ventilation. Natural ventilation, as its name implies, is an air circulation under the wind pressure formed by the outdoor wind force and the thermal pressure caused by the temperature difference between indoor and outdoor air. It is a non dynamic ventilation mode based on natural factors. Due to the instability of natural factors, it is rarely used by industry alone and often combined with other methods.
          (5)事故通风。事故通风,是工业中非常特殊的一类通风方式,通常是因工业事故而造成的有大量毒害污染物,或有爆炸隐患的气体或蒸汽存在时进行排除或稀释的一种通风方式,旨在保证事故发生时,能够有足够可靠的通风管道来应对通风换气量。实际上,要想实现更全面的通风效果,普遍会结合采用至少两种通风方式。
          (5) Accident ventilation. Accident ventilation is a very special type of ventilation mode in industry. It is usually a ventilation mode to eliminate or dilute a large number of toxic pollutants or gas or steam with explosion potential caused by industrial accidents. It aims to ensure that there are enough reliable ventilation pipes to cope with the ventilation volume in case of accidents. In fact, in order to achieve a more comprehensive ventilation effect, at least two ventilation modes are generally combined.
