Behind the rapid development of our country's economy is the increasingly serious problem of environmental pollution. Coal is the main energy consumed in China. However, during the combustion process of coal, a large amount of pollutants are generated, especially some dust particles, which can cause respiratory problems for people. Air pollution has become a major problem that urgently needs to be solved in modern times, and the reasonable treatment of coal-fired boiler flue gas emissions is of great significance for the protection of China's atmospheric environment.
to this endBotou Huiyang Company has designed and produced a boiler flue gas ammonia desulfurization and dust removal deviceOur company is willing to uphold the essence of cooperation for development, make extensive friends in related industries, and work together to create the glory of our country's environmental protection cause. The following is an introduction to the ammonia desulfurization and dust removal system for 80T boiler flue gas. I believe it will be helpful to you.

1、 Principle of ammonia desulfurization and dust removal device for 80T boiler flue gas:
The absorption process mainly involves the reaction of ammonia and SO2 in ionic form:
2NH3＋H2O＋SO2 → (NH4)2SO3
(NH4)2SO3＋H2O＋SO2 → 2NH4HSO3

The oxidation process mainly utilizes air to generate (NH4) 2SO4
(NH4)2SO3＋O2 → (NH4)2SO4
NH4HSO3 ＋O2→NH4HSO4
NH4HSO4 ＋NH3 → (NH4)2SO4
Principle of ammonia based denitrification:
The NOX in flue gas is mainly NO and NO2, with NO accounting for more than 90%. The (NH4) 2SO3 produced by desulfurization is a reducing agent that can reduce NO in flue gas to N2. The main reaction equation is:
2（NH4）2SO3+2NO（g）=2（NH4）2SO4+N2

This principle can remove a large amount of NO without the need for catalytic devices, and the higher the sulfur content in the flue gas, the greater the (NH4) 2SO3 produced, resulting in higher denitrification efficiency.

2、 Process flow of ammonia desulfurization and dust collector for 80T boiler flue gas:Using ammonia water as the desulfurization absorbent, it is mixed with the flue gas entering the absorption tower. The SO2 in the flue gas reacts with ammonia water to produce ammonium sulfite, which is then oxidized with forced oxidizing air to produce ammonium sulfate solution. After cooling
After crystallization, centrifugal dehydration, and drying in a dryer, the chemical fertilizer ammonium sulfate is produced. The ammonia method belongs to wet desulfurization technology.

1. After forced external circulation evaporation and crystallization, it is sent to the thickener and separated by a centrifuge (1 centrifuge).
2. Material: Made of titanium

This system has the following advantages:
1. According to the characteristics of the materials and the conditions of the incoming materials, a forced evaporation process is adopted, which is systematic and stable.
2. Heat transfer, high operational flexibility, and smooth operation.
3. Adopting vacuum operation, the evaporation temperature is low and equipment corrosion is reduced.
Process idea 1: Simple route
Maximizing comprehensive benefits
Cost advantage: 1. Low raw material cost.
2. By using vacuum evaporation method,
Process environment advantages: This project has high process controllability, easy operation, good stability, and low energy consumption. Moreover, the raw materials and substances generated during the production process will not have a harmful impact on the environment. Due to the resolution of raw material issues, production costs have been reduced.
