用於水產養殖系統中二氧化碳去除的脫氣塔 | YUTANK

特徵

• 高效二氧化碳汽提
  採用垂直塔結構化填料，最大程度增加氣液接觸面積。在實際試驗中，閉環羅非魚系統中的二氧化碳濃度在不到40分鐘內從18毫克/升降至5毫克/公升以下。

• 無腐蝕性、RAS 相容材料
  水箱採用工業級 HDPE 或 PP 材質製成，耐鹽水和消毒劑侵蝕。所有配件均可與公制和英制 PVC 管道系統整合。

• 重力或泵浦驅動選項
  可根據系統佈局進行配置。許多國際客戶選擇重力供料塔，以達到低揚程裝置的節能效果。

• 整合噴霧集管和通風口
  每個裝置都包括一個預先安裝的噴霧分配系統，用於均勻的水分散和氣體交換，以及通風口，以便在需要時支援強制排氣。

• 模組化高度擴展
  柱子高度是模組化的，以滿足不同的脫氣需求——根據流量和二氧化碳負荷，常見範圍從 1.2 公尺到 2.5 公尺。

• 免工具維護通道
  頂部無需工具即可進行維修，簡化了 RAS 計劃停機期間的介質清潔或更換。

• 在全球專案中得到驗證的效能
  安裝在東南亞的海洋孵化場、拉丁美洲的蝦場和北歐的循環農場，在各種放養條件下均能達到一致的二氧化碳減排效果。

Packaging
Each degassing tower is wrapped in PE protective film and supported with internal foam padding. For export shipping, units are secured on fumigation-free plywood pallets or enclosed in steel-framed wooden crates, depending on the container type and destination regulations. All inlets, outlets, and open sections are capped or sealed to prevent dust and transit damage.

Shipping & Logistics
Standard lead time for regular sizes is 12–18 working days. For OEM units or oversized configurations, production may take 20–25 working days. We support both LCL and FCL shipments, and offer FOB, CFR, and DAP terms through major ports in East and Southeast Asia. Pre-shipment inspection photos and dimension drawings are provided before container loading.

Documentation
Each shipment includes a commercial invoice, packing list, and product specification sheet. Additional documents such as Certificate of Origin (Form A, E, or FTA-compliant), MSDS, and SGS test reports can be arranged if required by the importing country.

Labeling & Traceability
All tanks are tagged with a laser-etched stainless steel ID plate showing model, flow capacity, and batch code. A digital label (QR code) linking to the operation manual and maintenance guide can be customized upon request.

FAQ — Degassing Towers for Aquaculture Systems

Q1: How does a degassing tower actually reduce CO₂ in RAS systems?
A: Degassing towers force water through a high-surface-area media bed using counter-current airflow. This process facilitates the release of excess CO₂ via gas exchange. In most RAS setups, a properly sized tower can reduce CO₂ levels from 20–25 mg/L to under 10 mg/L before the water enters the oxygenation zone.

Q2: Can these degassing towers be integrated with existing drum filters or oxygen cones?
A: Yes. Our towers are modular and flange-compatible with common RAS equipment. Many clients retrofit them between mechanical filtration (drum or settler) and the biofilter zone. The outlet height and flange diameter can be adjusted to match existing hydraulic layouts.

Q3: What materials are used, and are they safe for saltwater applications?
A: We use marine-grade FRP or food-safe PP depending on client preference. Both are UV-resistant and corrosion-resistant. For saltwater hatcheries or high-salinity shrimp farms, FRP with vinyl ester inner lining is recommended for durability.

Q4: Do I need a separate blower or ventilation system for gas stripping?
A: Typically, yes. For passive systems, natural draft may work for small-scale tanks, but most commercial farms use low-pressure blowers (300–700 Pa) to ensure efficient CO₂ removal and oxygen replenishment.

Q5: Can I request custom tower height, internal media type, or access ports?
A: Absolutely. We offer OEM support on tower height, internal splash media (random packing, structured sheet, etc.), and maintenance access points. Just provide basic flow parameters and system layout.
