废气处理方法之一 掩蔽法
Masking method, one of the methods of waste gas treatment
脱臭原理:采用更强烈的芳香气味与臭气掺和,以掩蔽臭气,使之能被人接收。
Deodorization Principle: Use stronger aromatic odor mixed with odor to mask odor and make it acceptable to people.
适用范围:适用于需立即地、暂时地消除低浓度恶臭气体影响的场合,恶臭强度2.5左右,无组织排放源。
Scope of application: It is suitable for the occasion where the effect of low concentration odor gas needs to be eliminated immediately and temporarily. The odor intensity is about 2.5 and the source of unorganized emission is unorganized.
优点:可尽快消除恶臭影响,灵活性大,费用低。
Advantages: It can eliminate the odor effect as soon as possible, with great flexibility and low cost.
缺点:恶臭成分并没有被去除。
Disadvantage: Stench ingredients have not been removed.
2、废气处理方法之二 稀释扩散法
2. Waste Gas Treatment Method II Dilution Diffusion Method
脱臭原理:将有臭味地气体通过烟囱排至大气,或用无臭空气稀释,降低恶臭物质浓度以减少臭味。
Deodorization principle: the odor gas will be discharged into the atmosphere through the chimney, or diluted with odorless air, reducing the concentration of odor substances to reduce odor.
适用范围:适用于处理中、低浓度的有组织排放的恶臭气体。
Scope of application: It is suitable for the treatment of medium and low concentration of odorous gases discharged by organizations.
优点:费用低、设备简单。
Advantages: low cost, simple equipment.
缺点:易受气象条件限制,恶臭物质依然存在。
Disadvantage: Vulnerable to meteorological conditions, odorous substances still exist.
