The concentration of NOx in the flue gas of glass kilns is as high as 1,500~3,500ppm. There is a lot of dust, and it contains potassium, sodium, boron, and silicon. The fine dust harms the tradition SCR and cannot be collected by Electrostatic precipitator; it is difficult to use filter bags to remove dust; ABS hazards also cannot be improved

The high-temperature flue gas of the kiln first passes through the cooling system. After the flue gas temperature is adjusted to 360~380°C, hydrated lime and ammonia are sprayed into the flue gas. After fully mixing with the flue gas, the flue gas enters the ceramic filter tube integrated desulfurization, denitrification and dust removal system. After treatment The standard flue gas is sent to the outside of the chimney through the induced draft fan to complete the entire desulfurization, denitrification and dust removal process.

The traditional flue gas treatment system has many processing steps, a large number of equipment, a large area, and a large enterprise investment; the cost of later operation is high. 例えば, due to the use of high-temperature electrostatic precipitator, the electrodes are often covered with dust and need to be cleaned frequently; desulfurization The calcium carbonate, calcium sulfite, and calcium sulfate waste residue generated during the process requires solid waste treatment.

1. Place the fiber sealing gasket between the ceiling plate and the filter tube flange, and then install the filter tube through the ceiling plate hole;
2. Place the venturi tube on the ceiling plate flange;
3. Place the fastening cover on the venturi:

4. Set it above the sleeve jacket and the fastening bolts (the fastening bolts should pass through the reserved bolt holes in the ceiling plate from bottom to top before installing the filter tube, and be fully welded to the lower part of the ceiling plate);
5. Retract the bolts and the installation is completed.

Fine dust, sulphur dioxide emissions and nitrogen emissions caused by high melting temperatures can all cause poor air quality. As a result, the glass, cement and metal industries, chemicals and petrochemicals as well as waste incineration and recycling plants – like many other industrial sectors – face the same challenge: Filtering and dedusting flue gases and pollutants as efficiently as possible and reducing their emissions.

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.
