Application results:

NOx emission concentration＜100mg/m3,
HF emission concentration <5mg/m3,
SO2 emission concentration <50mg/m3,
Particulate matter emission concentration <20mg/m3,
Ammonia escape <5ppm.
The pressure loss resistance of the integrated system is less than 2500Pa.
Calcium hydroxide adsorbent is used for desulfurization, defluorination and other acidic component removal. Secondary pollutants are powders such as calcium sulfate, calcium fluoride, calcium chloride and other salts. These powders can be recycled as ingredients in glass production.

TYPICAL ADVANTAGE

1. Realized the integration of desulfurization and dust removal, denitrification and dust removal. The denitrification efficiency is more than 90%, and the dust removal efficiency is 99%, saving equipment and investment;

2. Ceramic filter tubes have a long service life, averaging more than 5-8 years. Traditional cloth bags can be used for about 1.5 years in dust removal in the glass industry;

3. The overall operation of the equipment consumes low energy. After high-temperature ceramic fiber filter tube denitrification and dust removal, the nitrogen oxides and particulate matter in the flue gas are nearly purified, and the frequency and amount of high-pressure air backflush ash are greatly reduced, saving operation and energy costs;

4. The entire system adopts a pure dry flue gas purification process, and the intersecting wet desulfurization has no smoke tail, no need for dewhitening, no desulfurization wastewater, and no secondary pollution.

5. More importantly, the by-products after denitrification and dust removal in this project can be directly reused as ingredients for glass production, truly realizing the transformation of waste into treasure with zero emissions and realizing green production through material recycling.

DETAILED INTRODUCTION

Scope of application

1. High temperature dust removal
Ceramic-like material: CF filter element composition, alumina and silicon oxide content exceeds 97%, ceramic-like material can withstand high temperature, acid and alkali (except HF)

2. Acid separation collects acid solid hazardous waste. Through evaporation, the acid passes through the filter element in gaseous form, and the acid is collected by cooling to achieve the purpose of acid separation, effectively handle acidic hazardous waste, soil remediation, etc.

3. Precious metal recycling
Metals exist in solid form in high-temperature flue gas, and precious metals in flue gas can be collected through gas-solid filtration and separation.

By utilizing the different temperature ranges of metals, they exist in the form of solid and gaseous states, and by utilizing the different properties of their boiling points, the mixed metals are separated to achieve the purpose of separation and utilization.
