Further, the soaking time in step S2 is 15-20min per batch, and the air drying time is 200-300 min.
Further, the substrate plate of the silicon carbide is a foam silicon carbide ceramic plate.
Further, the deodorizing method of the malodor eliminating apparatus includes the steps of:
s1, allowing the odor gas to enter through the air inlet end of the
s2, enabling the gas to enter an F6-level
s3, the gas enters an oxidation bed A3 to carry out oxidation reaction after passing through a F6-
s4, the gas passes through the oxidation bed A3 and then enters the oxidation bed B4 to carry out composite reaction.
The working principle is as follows: when the malodorous pollutant factors in the odorous gas diffuse to the active centers on the surface of the oxidation bed A3 or the oxidation bed B4 in a dynamic form, the malodorous pollutant factors chemically react with the oxidized molecules on the oxidation bed A3 or the oxidation bed B4. According to the transient reaction mechanism, the malodor contaminating factors are decomposed into small molecular compounds and odorless molecules. So that the deodorizing effect can be achieved,
the peculiar smell gas of the toilet mainly comprises:
hydrogen sulfide H2S, having an egg odor;
ammonia NH3, a strongly irritating gas;
methanol CH3SH, having rotten cabbage smell;
fecal odor C9H9N, with putrefactive odor of feces liquid and feces;
the specific reaction mechanism is as follows:
hydrogen sulfide:
ammonia
Methyl mercaptan:
skatole:
to explain further: sulfate radicals (SO4) are radicals with higher redox potentials and are therefore believed to oxidize most organics under ideal conditions, as detailed in the above reaction mechanism.
The surface of the silicon carbide ceramic substrate plate is of a micropore accumulation structure, and the specific surface area is very large. When the substrate plate carries an oxidizing agent to perform oxidation reaction, the surface of the substrate plate is basically free of residues. When the struvite is loaded with sodium dihydrogen phosphate and magnesium sulfate, the struvite is sensitive to humidity in the air and is collected on the surface of the substrate after a long time to form struvite;
sulfate radicals attack N bonds and H bonds and directly destroy skatole structures to form heterocyclic substances and organic weak acids;
after the reaction with the oxidation bed A3 and the oxidation bed B4, the treatment process can be completed without any auxiliary conditions except for the need of fixing the flow rate of gas in the
