Desulfurizers generally refer to agents that remove free sulfur or sulfur compounds from fuel, raw materials, or other materials; In the control and treatment of pollutants, it mainly refers to the ability to remove sulfur from exhaust gas

Chemicals used for oxides (including SO2 and SO3). Various alkaline compounds can be used as desulfurizers.

This mixed solution desulfurizer has surface activity, catalytic oxidation, and can promote the direct reaction of SO2, accelerate the dissolution of CaCO3, and promote the rapid oxidation of CaSO3

Quickly oxidize to CaSO4, enhance the precipitation of CaSO4, reduce the liquid to gas ratio, decrease the calcium to sulfur ratio, and reduce the evaporation of water. When the concentration of SO2 at the flue gas inlet increases,

When the pH value in the absorption tower reaction tank decreases above the design value and a larger Ca/S ratio is required, without expanding the volume of the absorption tower reaction tank,

CaCO3 can dissolve quickly, increase the concentration of calcium ions, maintain the pH value of the slurry within the normal range, and have a certain buffering effect on the pH. Extended working period slurry

The running time of the liquid and reducing the number of slurry preparation times can significantly reduce equipment scaling, thinning the scale layer. After shutdown, washing with water can easily cause the scale layer to fall off. To take off

The scaling of the sulfur system causes dispersion and activity, reduces the accumulation of scaling, decreases the content of chloride ions in the slurry, and corrodes various materials in the desulfurization equipment

The scaling rate has been reduced to varying degrees, with carbon steel showing a greater reduction. Corrosion and scaling rates can be reduced by 74% and 79%, respectively, while polyvinyl chloride can reduce them

48% and 55%. The addition of desulfurizer can play a role in scale inhibition, anti-corrosion and corrosion inhibition, reducing the blockage, scaling, corrosion and wear of desulfurization nozzles, and reducing slurry

The scaling, corrosion, and wear of the liquid circulation pump and impeller reduce the maintenance and replacement of spare parts in the desulfurization system. Expand the selection range of desulfurization materials and improve

High system reliability. Under different operating conditions, the slurry circulation pump and oxidation fan can be reduced or stopped to improve desulfurization efficiency, reduce operating costs, and be suitable for

Changes in sulfur content in blended coal and its applicability to high sulfur coal. In the application of flue gas desulfurization, it has broad market promotion advantages and can generate considerable economic benefits

Benefit and social benefits.

Requirements for the use of desulfurizer:

(1) The desulfurization tower generally does not require special heating and consumes energy, but the outdoor desulfurization device must be insulated in winter to prevent the gas from overcooling and reduce the activity of the desulfurizer

Deterioration caused by water accumulation on the bed.

(2) Before desulfurization, efforts should be made to remove tar and water bubbles.

(3) The desulfurizer can be replaced in one go or in sections according to the direction of the airflow.

(4) Regularly discharge the water separator in front of the desulfurization tower and the accumulated water at the bottom of the desulfurization tower. It is strictly prohibited for gas to enter the desulfurization tower with liquid.

(5) The operation should be stable and the use should be reasonable to maximize its excellent performance.
