The plate aerator is an EPDM with a long plate and a membrane thickness of not less than 1mm The silicone rubber film PVC/PP stainless steel bolt is fixed in the middle of the support plate.
The models of plate aerators include DN650-150.DH1100-200, and the opening area of the entire aeration membrane should be greater than 0.78m2 and 0.176 ㎡, with a bubble diameter of 1-3mm. Ethylene propylene diene monomer (EPDM) rubber sheet Or silicone rubber (SI), with special additives added to enhance its physical properties. The air entering the plate aerator does not require air purification. It can be used continuously for a long time or stopped before being put into use, and there will be no micro pore blockage or mixture reflux.
The plate aerator intakes air through the threaded hole at the lower end of the support plate. The air distribution pipe is fixed at the bottom of the pool with a specific adjustable support, which can meet the requirements of up and down adjustment, make up for the error caused by the uneven bottom of the civil engineering pool, and adjust back and forth to prevent damage to the pipe caused by thermal expansion and cold contraction.
The microporous aerator should be suitable for a working temperature of 90 ℃. Each vertical pipe must be equipped with a set of condensate drainage device to drain the accumulated water in the pipeline. The device consists of one unit. Insert 20 DN20 thin tubes into the bottom of the air branch pipe and use the principle of air lift to remove moisture. The thin tube leads vertically to the upper part of the water surface and is controlled by a manual valve to remove condensed water.
Air distribution pipeline
In the process of manufacturing air delivery pipes and their connectors, it is necessary to use raw material UPVC particles mixed with a certain proportion of additives to prevent strong oxidation such as ultraviolet radiation and extend the service life of the pipes.
When the length of a single pipe is greater than 200m, an expansion joint should be equipped to allow the pipeline system to expand and contract to a certain extent, preventing pipeline damage caused by large temperature differences and pool settlement. The pressure rating of the air exhaust pipe is 11.0Mpa.
The vertical total air distribution pipe bracket should be adjustable within a range of ± 50mm. The support bracket of the air distribution branch pipe should allow for longitudinal movement, have sufficient anchoring force, and be adjustable within ± 50mm in the vertical direction. The main pipe at the bottom of the pool should be equipped with a drainage device. The air entering the tubular aerator does not require dust removal and purification. After long-term continuous use and cessation of use, it should meet the requirements and not cause blockage.
Bracket system
There are two types of gas supply pipe support systems: guided and fixed, made of AISI304 stainless steel. The bracket installation is simple, adjustable up and down, and easy to install and adjust when the pool bottom is tilted or uneven. The bracket is fixed with high-strength chemical anchoring, and the fixed components have sufficient anchoring force to prevent the air pipeline from floating under buoyancy. The spacing between pipeline supports should be less than 2.0m.
Condensate discharge pipe
Reasonably select and equip a condensate discharge system. Ensure that condensed water in the air duct can be discharged under any circumstances to ensure safe gas supply.
