用于水产养殖系统中二氧化碳去除的脱气塔 | YUTANK

特征

• 高效二氧化碳汽提
  采用垂直塔结构化填料，最大程度增加气液接触面积。在实际试验中，闭环罗非鱼系统中的二氧化碳浓度在不到40分钟内从18毫克/升降至5毫克/升以下。

• 无腐蚀性、RAS 兼容材料
  水箱采用工业级 HDPE 或 PP 材质制成，耐盐水和消毒剂侵蚀。所有配件均可与公制和英制 PVC 管道系统集成。

• 重力或泵驱动选项
  可根据系统布局进行配置。许多国际客户选择重力供料塔，以实现低扬程装置的节能效果。

• 集成喷雾集管和通风口
  每个装置都包括一个预装的喷雾分配系统，用于均匀的水分散和气体交换，以及通风口，以便在需要时支持强制排气。

• 模块化高度扩展
  柱子高度是模块化的，以满足不同的脱气需求——根据流量和二氧化碳负荷，常见范围从 1.2 米到 2.5 米。

• 免工具维护通道
  顶部无需工具即可进行维修，简化了 RAS 计划停机期间的介质清洁或更换。

• 在全球项目中得到验证的性能
  安装在东南亚的海洋孵化场、拉丁美洲的虾场和北欧的循环农场，在各种放养条件下均能实现一致的二氧化碳减排效果。

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.
