Odors in multi-story factory buildings interact with each other. How should chemical filtration be divided?
When odors interact with each other in multi-story factory buildings, chemical filtration should be divided according to air flow paths, pollution sources and area protection objectives. The floor itself is not a sufficient basis. Shared shafts, return air or door opening paths may cause cross-floor transmission.
Locate the communication channel first
Compare floors, shafts, fresh air inlets and return air, and record production and door area status. The location where the odor is concentrated is not necessarily the location of the source.
Reduce unreasonable air series connection
Exhaust air, differential pressure and return air zoning should be checked to prioritize preventing contaminated air from entering sensitive areas. Adding filter elements to each layer cannot be used instead of path rectification.
Match target ingredients in each area
The materials and contamination on different floors may be different, and the filter materials and acceptance targets should be checked separately. The shared system also needs to confirm the air volume distribution after the resistance changes.
Project judgment example
When an odor occurs in a high-rise building after a low-rise operation, the vertical channels and shared return air can be investigated, and then source control and zoning filtration can be compared.
Selection check points
Write the following four items into the evaluation record to facilitate product comparison, trial and subsequent review using the same conditions.
| for inspection items | Confirm key points | for inspection items | Confirm key points |
|---|---|---|---|
| propagation channel | Check shaft and return air | Source area | Record tasks and time periods |
| partition target | Clarify the requirements for each layer | system balance | Review branch air volume and pressure difference |
Aili Industrial products and equipment supporting
Aili Industrial provides a series of chemical filter products and related clean air equipment. You can compare FFU supporting, box-type, flat-type and V-type products based on the target gas and installation location, and then check the air volume, resistance and related detection conditions. Aili Industrial's R&D and production of motors and fans, control systems, sheet metal, filters and complete machine assembly capabilities can be used to configure the connection between the filter section and the air supply equipment; the specific gas applicability and performance still need to be confirmed based on the model, filter material and usage conditions.

summary
When odors interact with each other in multi-story factory buildings, chemical filtration should be divided according to air flow paths, pollution sources and area protection objectives.
