VOCs处理 - 模组化设备

VOCs Concentrator Rotor

VOCs Concentrator Rotor (HAR)

在处理大风量的低浓度VOCs废气时都需要大型设备，大大增加了初始成本和运行成本。
通过使用VOCs Concentrator Rotor，可以将大风量含有低浓度的VOCs废气浓缩为高浓度的低风量，高效的处理含有 VOCs 的废气。

Choices of Adsorption Media

  • Match the adsorbent media to the emissions in the process
  • Zeolite vrs. Carbon – Complimentary Rather Than Competing Technologies
    • Structural Differences
    • Applications Differ
    • Adsorption Characteristics Differ

Removal Efficiency relates how:

VOC is transferred from large air volumes to adsorbent media prior to exhausting to atmospher

如何涉及去除效率：

VOC 在排放到大气之前从大风量转移到吸附介质

Concentration Technology

Concentrators are CAPTURE Devices

  • VOC are removed from process air by adsorption
  • Adsorption media is continuously regenerated
  • VOC destruction after concentrator becomes very economical

浓缩技术

集中器是捕获设备
  • 通过吸附从制程空气中去除VOC
  • 吸附介质不断再生
  • 经由浓缩器后的VOC销毁变得非常经济

Suitable Applications for Concentrators

High air volume – low VOC concentration

VOC Concentration <800-900 ppm

  • Process exhaust temperature <120°F
  • No resin, heavy metals, or oils present
  • No halogenated compounds present
  • No sulfur compounds present

CarbonRemoves xylene and most common paint solvents.
Ineffective at removing methanol.
Zeolite with
6Å pores		Removes methylene chloride, methanol and most low-molecular-weight solvents. Somewhat less effective with xylene and solvents larger than 6Å diameter.
Zeolite with
8Å pores		Removes higher-molecular-weight solvents.

and zeolite
in a series		weight solvents.
Removes solvent mixtures containing moderate
amounts of methanol (15% to 25%) at low total
VOC loadings (less than 250 ppm). Note that a physical mixture of carbon and zeo-lite on a single substrate is more effective than the two in series at removing high
concentrations of solvents (>300 ppm) with lower
(<20%) alcohol contents.
