Overview

The desulfurization and defoaming agents used in power plant water treatment are different from other defoaming environments. Because the composition of desulfurization slurry is different from that of water treatment wastewater. Most thermal power plants in China use the method of burning coal. The desulfurization foaming not only increases the workload and brings trouble to the operation, but also pollutes the working environment, so it is necessary to use desulfurization defoamers.

Product Details

Power plant water treatment desulfurization and defoaming agent

1. Product Features

Made by polymerizing special organic compounds with substances such as propylene oxide, ethylene oxide, and related catalysts;

Quickly reducing gas-liquid surface tension, fast defoaming speed, long foam suppression time, can effectively prevent overflow of absorption tower slurry;

The addition amount is small, 0.5-1.0kg per 2000m3 of slurry;

It is easily dispersed in water and does not react chemically with any substances in the slurry;

Strong stability, acid resistance, and high temperature resistance;

No corrosion, no adverse side effects.

2. Product physical characteristics

Appearance: Colorless or pale yellow transparent liquid

Hydroxyl value KOH mg/g: 45.0-55.0

Acid value KOH mg/g: ≤ 0.05

3. Operating instructions

Joining point: in the absorption tower pit;

Addition method: intermittent periodic impact dosing or continuous dosing by metering pump;

Dosage: When foaming overflow occurs in the absorption tower, generally 1.0-2.0kg should be added in a single impact manner. The actual dosage should be determined based on the composition of the foaming agent, the amount of flue gas, the composition of the coal, the combustion process, the amount of absorbent, and the amount of sulfur dioxide;

Dosing frequency: The specific dosing frequency depends on the foaming situation of the absorption tower and does not require regular dosing.

4. Packaging and Storage

25kg/plastic drum packaging;

Store in a clean, cool, ventilated, and dark warehouse;

Avoid direct sunlight and rain during transportation, and pay attention to fire prevention;

Shelf life at room temperature: one year.

5. Testing method:

1. Laboratory trial: Use standard laboratory trial equipment to simulate the performance of desulfurization and defoaming agents under actual operating conditions.

2. Pilot and engineering trials: Conduct pilot and engineering trials in actual desulfurization systems to evaluate the performance and effectiveness of desulfurization defoamers.

3. On site monitoring: During the actual operation of desulfurization in power plants, monitor the use and effectiveness of desulfurization defoamers, collect data for evaluation.

Power plant water treatment desulfurization and defoaming agentThe performance evaluation indexes include foam inhibition effect, desulfurization efficiency, chemical performance and environmental impact. The performance of desulfurization defoamer can be evaluated by measuring the foam height, foam duration, SO2 removal rate and gypsum output.
