How to use desulfurization and defoamer in power plants? What does it do?

Power plant desulfurization and defoamer is specially developed for flue gas desulfurization slurry foaming system, which has transparency, good compatibility, fast defoaming and foam inhibition performance, so as to control the liquid level in the tower, remove the false liquid level caused by foam, prevent slurry overflow, and slow down the problem of scaling and clogging of heat exchanger (GGH) caused by foam.

When using, it can be added directly, or diluted with water and working night and stirred evenly to save the amount of use. The amount of use is determined according to the foam situation on site, and the amount of use is adjusted, and the scope of use is in, but it should also be based on the foaming degree of the defoaming system. After each use, the container should be strictly sealed and stored in a cool, ventilated and dry place indoors, with a shelf life of 12 months.

The desulfurization and defoamer can be added directly to the desulfurization tower, and the addition amount is between 1 and 5, depending on the amount of foam.

Add it directly and use it in about one thousandth.

When using the defoamer, it needs to be thoroughly stirred, first diluted reasonably, and then stirred until it is homogeneous. After the on-demand ratio is completed, it needs to be used up in a short period of time. It is also necessary to protect the defoamer from frost and high temperatures, as the defoamer can affect performance under frost and high temperature conditions.

1.Before the use of desulfurization and defoamer in power plants, tests should be carried out to determine the applicability;

2.Use warm and stir before warming;

3.Calculation of dosage: the general amount of defoamer added source is 1 5, and the final amount is based on the actual experiment, and the amount of slurry is taken as the standard under normal operation.

The first time this product is added, it should be added at one time, and then added at one time every 24 hours, but the determination of the actual dosage is related to the composition of the foaming liquid, the amount of flue gas, the composition of coal and the working conditions of combustion, absorbent, and sulfur dioxide. The user unit can finally determine the dosage according to the actual situation.

4.In the process of continuous addition, the addition can be calculated by the pump and added once in the intermittent D process.

Power plant defoamer is used to solve the foaming problems encountered by each power plant chemical additives, the power plant bubble problem can not be better solved, serious may even occur, power plant defoamer is used to solve the foaming problem encountered in each power plant.

Add 1 thousandth to 3 thousandths directly.

What is the composition of the desulfurization and defoamer for power plants? Its main ingredient is polysiloxane. The desulfurization and defoamer of power plant is specially developed for the foaming of the slurry of the flue gas desulfurization absorption tower, and is only used for the special defoaming of the desulfurization slurry of the power plant, which is used to inhibit the foaming overflow of the absorption tower and prevent the slurry backflow at the entrance of the absorption tower.

Power plant desulfurization defoamer is harmless, in addition to being used in power plant desulfurization, it can also be used in desulfurization coatings, steel mill desulfurization, natural gas desulfurization, and thermal power plant desulfurization.

Power plant desulfurization defoamer is a polysiloxane type defoamer, which has unique chemical inertness and is widely used in various kettle and tower reactions. And it does not cause any harm to the process. With:

1. It can quickly eliminate the inflated liquid level caused by foam, effectively prevent slurry overflow, and greatly alleviate the problems of scale and clogging of heat exchanger (GGH) caused by foam.

2. It can absorb the foam produced in the process of limestone slurry washing in the flue gas desulfurization system, and effectively prevent the ash accumulation at the entrance of the absorption tower.

3. Excellent compatibility, can continue to inhibit foam for a long time, maintain stable defoaming, and greatly improve the efficiency of desulfurization.

It can prevent some accidents caused by slurry overflow, and the desulfurization and defoamer of Zhongfeng Power Plant is composed of special organic compounds and modified silicone polyethers, which can well inhibit the flue gas from producing a large amount of foam in the process of being washed by limestone slurry in the absorption tower of the wet desulfurization system, and prevent ash accumulation at the entrance of the absorption tower.

The use of desulfurization and defoamer in power plants mainly includes the following:

Homogeneous mixing in proportion: The defoamer is added to the desulfurization system in a certain proportion, and then evenly mixed by stirring and other means.

Direct dosing: The defoamer is directly put into the desulfurization system, and evenly dosing by spraying and other means.

Liquid injection: The defoamer is injected into the liquid in the desulfurization system and evenly dispersed by stirring, etc.

Spraying surface: The defoamer is sprayed onto the surface of the desulfurization system and evenly dispersed by means of air flow.

It should be noted that different power plant desulfurization defoamers have different use methods and dosages, and the specific use methods and dosages need to be reasonably designed and adjusted according to specific conditions. At the same time, it is necessary to pay attention to safety and environmental protection when using it to avoid pollution and harm to the human body and the surrounding environment.

Power plant desulfurization defoamers typically have the following effects:

Inhibition of oxidation reaction: Since the desulfurizer will be in contact with the oxygen in the gas during the use of the desulfurizer to produce an oxidation reaction, the defoamer can inhibit the occurrence of this oxidation reaction and prevent the corrosion and blockage of equipment and pipelines by reaction by-products.

Reduced surface tension: The defoamer can reduce the surface tension at the interface between liquid and gas, so that the gas can be quickly separated from the liquid, and Panapure avoids the problem of excessive bubbles.

Reduce viscosity: Defoamers can reduce the viscosity of the solution, increase the diffusion rate of gases, and improve the desulfurization efficiency.

Dispersion particles: Defoamers can disperse particles, so that the particles are evenly dispersed, reduce agglomeration, and increase the fluidity of the liquid.

Improve stability: Defoamers can increase the stability of liquids, avoid excessive foam, liquid level fluctuations, etc., and ensure the normal operation of desulfurization equipment.

Power plant flue gas desulfurization defoamer is a chemical additive used in the flue gas desulfurization system of power plants, its main role is to improve the foam problem in the flue gas desulfurization process, and improve the desulfurization efficiency and stability.

Specifically, in the flue gas desulfurization system of the power plant, the lime milk formed after the mixture of calcium oxide (CAO) and water is sprayed into the flue gas through a sprayer, and reacts with the sulfur oxide (SO2) in the flue gas to generate calcium sulfate (CaSO4) and water vapor, so as to achieve the purpose of desulfurization. However, in the process of spraying lime milk, a large amount of foam is often generated, which will hinder the spraying and reaction of lime milk, resulting in a decrease in desulfurization efficiency and damage to desulfurization equipment.

Therefore, the main function of flue gas desulfurization defoamer is to eliminate or reduce the generation of foam, so as to ensure the normal operation of desulfurization equipment and the improvement of desulfurization efficiency. In addition, flue gas desulfurization and defoamer can also improve the dispersion and stability of lime milk, reduce the accumulation and clogging of calcium sulfate, thereby further improving the desulfurization efficiency and stability.

In short, the function of the desulfurization defoamer for flue gas desulfurization in power plants is to reduce foam generation and improve the dispersion and stability of lime milk, so as to improve the desulfurization efficiency and stability.

The functions of desulfurization and defoamers include:

Reduce precipitation: Desulfurization and defoamer can effectively prevent the disturbance of sulfur oxide precipitate and reduce the cleaning and emission of sedimentary paulownia.

Lower desulfurization temperature: Desulfurization defoamer can reduce the temperature of sulfur oxide oxidation and reduce energy consumption.

Reduced maintenance costs for desulfurization equipment: Desulfurization defoamers can reduce the maintenance costs of desulfurization equipment by reducing sediment generation and cleaning.

Power plant desulfurization and defoaming can be used to reduce the sulfide and sulfur dioxide content in the flue gas, and at the same time reduce the generation of flue gas foam. This can be used to improve the efficiency of flue gas desulfurization and reduce environmental pollution.

Power plant desulfurization and defoamer can inhibit the foam overflow in the power plant's desulfurization tower and prevent production accidents caused by inaccurate measurement.

In power plants, air bubbles generated during the desulfurization process can adversely affect equipment and processes. In order to eliminate these bubbles, the use of desulfurization defoamers can be employed. The following are the steps for the use of desulfurization and defoamer in power plants:

1.Understand the nature of the defoamer: Before selecting and using a desulfurization defoamer, you need to understand the nature, scope of application, and use of the defoamer. Different defoamers may have different uses and requirements for use.

2.Determine the dosage to be used: Determine the appropriate dosage of defoamer on a case-by-case basis. The determination of the dosage usually takes into account factors such as the type, size, and process parameters of the desulfurization equipment. You can refer to the recommended dosage provided by the defoamer** manufacturer.

3.Add defoamer: Add the identified defoamer to the desulfurization equipment or desulfurizer according to the recommended dose. The specific addition method can be carried out according to the design and operation requirements of the equipment, such as spraying, injection or mixing.

4.Mixing and stirring: Once the defoamer is added to the desulfurization system, it needs to be thoroughly mixed and stirred to ensure that the defoamer is evenly dispersed in the desulfurizer and is in effective contact with the bubbles.

5.Monitoring and adjustment: During the use of defoamers, monitoring and adjustment are required. The effect of the defoamer can be evaluated by observing the condition of the bubbles during the desulfurization process, the operating status of the equipment, and the quality of the product, and the dosage can be adjusted as needed.

It is important to note that the specific methods and procedures for the use of the rotation may vary depending on the desulfurization equipment and defoamer. Therefore, in practice, it is best to refer to the detailed instructions and cheat guidelines provided by the defoamer** manufacturer, and follow the operating procedures and safety requirements of the power plant.

The defoamer should be stirred fully before use to ensure that the liquid is uniform.

The mixing of desulfurization and defoamer in power plants with other oils and organic substances should be avoided as much as possible to prevent the reaction from producing toxins.

During use, attention should be paid to properly controlling the concentration of use to prevent corrosion or contamination caused by overdose.

It should be used in accordance with the instructions, and comply with relevant laws and regulations and safety operating procedures.

Care should be taken to prevent accidental ingestion, and if accidentally ingested, seek medical attention immediately.
