Different Content Requirements and Anti corrosion Technology of Desulfurization and Denitration Equipment

Desulfurization and denitration equipment is relatively cheap in overall operation cost and occupies a small area. It is a low income and efficient exhaust equipment, which can effectively solve the problem of air pollution. Therefore, it is widely used in cement chemical industry, thermal power generation, iron and steel smelting and other industries, mainly as flue gas treatment equipment. So today we will take a look at different content requirements and anti-corrosion technologies for desulfurization and denitrification equipment.

[Requirements for different contents of desulfurization and denitrification equipment]

1、 Requirements for oxygen content of desulfurization and denitrification equipment:

In fact, the desulfurization and denitrification equipment does not have very high requirements for the oxygen content, which can mainly ensure normal operation. If the oxygen content continues to increase, the opposite effect will occur. Under normal circumstances, the oxygen content in the gas can only be less than 0.5%, and the less the better.

2、 Requirements for carbon dioxide content in desulfurization and denitrification equipment:

Under normal conditions, the carbon dioxide content in the desulfurization and denitrification equipment is relatively stable. If the content exceeds the specified range, the loss on sodium carbonate will also increase, which is very unfavorable to H? The normal absorption of S will also lead to serious adverse effects, so its content is very important.

3、 Requirements for organic sulfur content in desulfurization and denitrification equipment:

Generally, the wet method can only remove a small amount of organic sulfur in the desulfurization, desulfurization and denitrification equipment, but it will directly convert it into H? S. Therefore, it will still have a serious impact on production. Therefore, it is effective to test the content of organic sulfur and consider it according to the data.

4、 H? In desulfurization and denitrification equipment? Content requirements of S:

Different raw materials H? The content of S is also different. If the load occurs in the production process of the desulfurization, desulfurization and denitrification equipment, it will not only affect the size requirements of the gas volume, but also lead to H? If S changes in content, effective testing of its content range is an effective way to ensure solution adjustment.

[Anti corrosion technology for desulfurization and denitrification equipment]

When the desulfurization and denitration equipment is working, some smoke gases will have a certain impact on the equipment in the process of long-term absorption and purification treatment. Compared with some equipment, some equipment has a certain corrosion effect, so this is why we should timely master some treatment measures for anti-corrosion technology.

First, we need to reasonably control the pH value. Secondly, during the operation, the inlet temperature of FGD flue gas shall be strictly controlled, and the matching anti-corrosion lining shall be selected to minimize corrosion. Third, attention should be paid to the strict control of the process quality when making the anti-corrosion lining.

In addition, when selecting materials, appropriate anti-corrosion materials should also be selected. According to the introduction of the desulfurization and denitration equipment company, for example, carbon steel body lining anti-corrosion materials or corrosion-resistant alloy materials can be used to control the degree of corrosion.

In the current production work, people pay more and more attention to environmental protection issues, especially thermal power plants will produce a lot of sulfur dioxide and nitrogen oxides in the production process, which will cause serious pollution to the atmosphere. Therefore, accelerating the research and production of desulfurization and denitrification equipment will play an important role in promoting sustainable development.

Nowadays, environmental protection has become the focus of attention. That is to say, we are also increasing our efforts in the purification of desulfurization and denitration equipment, and the purified products are also being improved and improved. Therefore, in many cases, what we need to do is to use the products correctly and do a good job in maintenance. The rest is left to the technical R&D personnel.
