Overview

The core principle of dry chemical deodorization is the combined action of two mechanisms: physical adsorption (odor molecules adsorbed on the surface or pores of the filter material) and chemical conversion (oxidation or neutralization reaction between odor molecules and chemical filter material, or chemical transformation process of catalytic decomposition into non-toxic, harmless, non corrosive, and odorless substances).

Product Details

Dry chemistrydeodorizeThe core principle is physical adsorption (odor molecules are adsorbed on the surface or pores of the filter material)And chemical transformationOxidation or neutralization reactions occur between odor molecules and chemical filter media,Or it can be catalytically decomposed into non-toxic, harmless, and non corrosive substancesCorrosive, noneThe chemical transformation process of odorous substancesTwo mechanisms work together. Utilize physical adsorption, chemical absorption, oxidant oxidation, and catalyst catalysis to decompose and convert volatile organic compounds, as well as odorous substances such as hydrogen sulfide, methyl mercaptan, and ammonia in the odor.

The deodorization system has high deodorization efficiency,Low operating costs，And it does not generate secondary pollution,Maintenance of the entire equipmentsimpleThe characteristic of low manual management cost. The medium can be activated carbon based dry chemical medium or high strength acid salt leachingStain activated oxidationAluminum medium.

Organized emissions are adopted after exhaust gas treatment,After the deodorization device is in operation,The emission of odorous pollutants must be less than or equal to《stenchPollutant Emission StandardsTable in GB 14554-931. Table 2 Emission Standard Values,among whichHydrogen sulfide is less than0.33kg/h,Ammonia gas is less than 4.9kg/h, The concentration of odor at the exhaust outlet is less than 2000 (dimensionless)），The concentration of odor at the factory boundary is less than20(Non dimensional).

Dry chemistrydeodorizeThe concentration of pollutants in the emitted gas should be lower than the "Environmental Air Quality Standards"(GB3095-2012) Class IIThe concentration limit of the area.

Comparison project	activated carbon adsorption	Chemical adsorption
Working principle	Physical adsorption, reversible, easy to release odor again	physical adsorption+Chemical absorption, irreversible
Target pollutants	VOCs (benzene, toluene) and ozone are ineffective against many pollutants	Formaldehyde, hydrogen sulfide, nitrogen oxides, gaseous pollutants Converted into harmless and odorless substances
Adsorption capacity	5-8kg H2S/100kg activated carbon	40-50kg H2S/100kg chemical filter material, adsorptionH2The power of S is 6-9 times that of activated carbon
flammability	Combustible substances	Flame retardant（UL certification)
toxicity	Toxicity exists	Human friendly, non-toxic, and harmless
replacement cycle	about3-6 months	about1-2 years, remaining lifespan can be accurately anticipated
Does it harbor bacteria	Microorganisms are prone to grow in humid environments	Inhibiting the growth of bacteria or fungi
The treatment effect when the concentration is low	Poor removal effect can cause desorption and increase the concentration of odor at the outlet	Regardless of the concentration, the removal efficiency remains stable
The treatment effect of high humidity exhaust gas	Poor removal effect, activated carbon will absorb water, resulting in inability to adsorb odors	5~95% humidity has no effect, containing a certain The water will enhance the removal efficiency
Removal effect at high temperature	The temperature is higher thanAbove 60 ° C, activated carbon is basically lost Adsorption may cause desorption	High temperature resistance, temperature has no significant effect on chemical filtration reaction
Waste characteristics	hazardous waste	Can be buried as general solid waste
Operation and maintenance	There are many ancillary facilities with a high failure rate	The manufacturing process is simple, with few ancillary facilities, low failure rate, and can be unmanned
