在現代環保工程中，生物除臭濾池作為一種高效、經濟的廢氣處理設備，其處理效能與廢氣流量之間存在密切的關聯性。以富方環保生產的生物除臭設備為例，該設備采用吸附原理，配備智能控制系統，處理風量可達12000m3/h，凈化效率超過98%，且具備95%的脫硫率和30dB的低噪音運行優勢。這些卓越性能的實現，離不開對廢氣流量的科學調控與系統設計。

In modern environmental engineering, the biological deodorization filter is an efficient and economical waste gas treatment equipment, and its treatment efficiency is closely related to the waste gas flow rate. Taking the biological deodorization equipment produced by Fufang Environmental Protection as an example, the equipment adopts the adsorption principle and is equipped with an intelligent control system. The processing air volume can reach 12000m 3/h, the purification efficiency exceeds 98%, and it has the advantages of 95% desulfurization rate and 30dB low-noise operation. The realization of these outstanding performances cannot be achieved without scientific control of exhaust gas flow and system design.

一、廢氣流量范圍的適應性設計

1、 Adaptive design of exhaust gas flow range

生物除臭濾池對廢氣流量的處理能力具有顯著的彈性空間。單體設備的處理范圍通常為200~20000m3/h，而富方環保的設備通過非標定制化設計，可靈活擴展至12000m3/h的風量需求。對于更高流量的工業廢氣，可采用模塊化組合方案，例如通過并聯多臺設備（如規格為1200*2500*9000mm的生物濾池單元）構建系統，既能滿足大規模處理需求，又能通過智能控制實現能耗優化。

The biological deodorization filter has significant flexibility in the treatment capacity of exhaust gas flow. The processing range of individual equipment is usually 200~20000m 3/h, while the equipment of Fufang Environmental Protection can be flexibly expanded to meet the air volume demand of 12000m 3/h through non calibrated design. For higher flow industrial waste gas, a modular combination scheme can be adopted, such as building a system by parallel connecting multiple devices (such as a 1200 * 2500 * 9000mm biological filter unit), which can meet large-scale processing needs and optimize energy consumption through intelligent control.

二、流量與濾池尺寸的協同優化

2、 Collaborative optimization of flow rate and filter size

濾池的物理尺寸直接決定了其處理能力。以圓柱狀反應器為例，其直徑和高度的設計需綜合考量廢氣流量、惡臭物質濃度（如1200mg/m3的典型處理濃度）以及空床停留時間（EBRT）。停留時間的設定尤為關鍵——較長的停留時間（通常通過增大濾池容積實現）可提升微生物對惡臭物質的降解效率，但需權衡設備投資成本。富方環保的生物濾池通過優化內部結構（如分層過濾設計）和60℃的后燃溫度控制，在有限空間內實現了更高效的污染物分解。

The physical size of the filter directly determines its processing capacity. Taking a cylindrical reactor as an example, the design of its diameter and height requires comprehensive consideration of exhaust gas flow rate, concentration of odorous substances (such as a typical treatment concentration of 1200mg/m 3), and empty bed residence time (EBRT). The setting of residence time is particularly crucial - longer residence time (usually achieved by increasing the filter volume) can improve the degradation efficiency of microorganisms towards odorous substances, but the equipment investment cost needs to be balanced. The biological filter of Fufang Environmental Protection achieves more efficient pollutant decomposition in a limited space by optimizing the internal structure (such as layered filtration design) and controlling the post combustion temperature at 60 ℃.

三、流量對除臭效能的動態影響

3、 The dynamic impact of flow on deodorization efficiency

廢氣流量超出設計閾值時，會導致濾池內微生物與污染物的接觸時間不足，顯著降低凈化效率。例如，若流量突然增至設備上限的12000m3/h以上，可能引發氣流短路或生物膜沖刷脫落。因此，富方環保的設備通過智能控制系統實時監測流量波動（配合10000m3/h的置換風量備用能力），動態調節風機轉速與閥門開度，確保廢氣在濾池內的停留時間穩定在最佳區間（通常為15~60秒），從而維持≥98%的凈化率。

When the exhaust gas flow exceeds the design threshold, it will result in insufficient contact time between microorganisms and pollutants in the filter, significantly reducing the purification efficiency. For example, if the flow rate suddenly increases above the upper limit of the equipment by 12000m 3/h, it may cause airflow short circuit or biofilm erosion and detachment. Therefore, the equipment of Fufang Environmental Protection monitors flow fluctuations in real time through an intelligent control system (with a reserve capacity of 10000m 3/h replacement air volume), dynamically adjusts fan speed and valve opening, and ensures that the residence time of exhaust gas in the filter is stable in the optimal range (usually 15-60 seconds), thereby maintaining a purification rate of ≥ 98%.

四、流量精準控制的技術實踐

4、 Technical Practice of Precise Traffic Control

為實現流量的精確管理，建議采取以下措施：

To achieve precise management of traffic, it is recommended to take the following measures:

硬件配置：安裝高精度流量計與電動調節閥，與生物濾池的智能控制中樞聯動，形成閉環調控系統。

Hardware configuration: Install high-precision flow meters and electric control valves, which are linked with the intelligent control center of the biological filter to form a closed-loop control system.

工藝適配：針對不同廢氣特性（如含硫化合物需95%脫硫率），定制滯留時間與風量配比，例如高濃度廢氣采用低流量長停留模式。

Process adaptation: Customize retention time and air flow ratio for different exhaust gas characteristics (such as 95% desulfurization rate for sulfur-containing compounds), such as using low flow long retention mode for high concentration exhaust gas.

維護保障：定期校準傳感器、清理送風管道，避免因設備老化導致流量測量誤差（如±5%的偏差可能使凈化率下降至90%以下）

Maintenance guarantee: Regularly calibrate sensors, clean air supply ducts, and avoid flow measurement errors caused by equipment aging (such as a deviation of ± 5% that may cause the purification rate to drop below 90%)
