Dry desulfurization and denitrification equipment manufacturer: Dry desulfurization and denitrification process
Author：
The integrated desulfurization and denitrification unit shows remarkable results. Integrated flue gas desulfurization and denitrification technology is one of the most effective methods currently available for controlling SOx and NOx emissions. In recent years, integrated flue gas desulfurization and denitrification technology has become a cutting-edge technology in the field of air pollution control due to its advantages of simplified equipment, small land occupation, low investment, and ease of use, as it simultaneously desulfurizes and denitrifies within the same system. Business Management. Research direction. Dry desulfurization and denitrification equipment manufacturer Generally speaking, desulfurization and denitrification technologies can be divided into three major categories: wet, dry, and semi-dry methods, based on the state of the desulfurizing agent and reaction products. Wet processes are mature, efficient, and widely used, but they have high costs, large land occupation, high water consumption, easy secondary pollution, ammonia leakage, equipment corrosion, and other problems; although dry and semi-dry processes still have some technical problems, they have become a very promising flue gas purification technology due to their advantages of low water consumption, low operating costs, simple equipment, and small land occupation.
Dry desulfurization and denitrification equipment manufacturers indicate that there are two denitrification technologies widely used in actual projects in China at present.
1. For small boilers, the commonly used denitrification method is to use a low-nitrogen burner for denitrification. Principle: A low-NOx burner, that is, a low nitrogen oxide burner, refers to a burner with low NOx emissions during fuel combustion. This equipment can reduce the emission of nitrogen oxides during combustion. Disadvantages: The combustion temperature will decrease, the fuel will increase by more than 8%, and the value of sulfur dioxide will increase.
2. Large boiler high-temperature denitrification SNCR method and medium-temperature denitrification SCR method: A reducing agent such as urea or ammonia water is injected into the boiler, and the catalyst causes the reducing agent to react with NOx in the flue gas, thereby removing NOx from the flue gas. Medium-temperature denitrification refers to selective catalytic reduction (SCR) denitrification with an efficiency of over 90%. Disadvantages: Spraying a large amount of aqueous solution into the boiler will generate ammonium sulfate, sulfurous acid, sulfates, etc., corroding boiler equipment and pipelines; in addition, injecting a large amount of water vapor will carry away a large amount of heat, leading to an increase in fuels such as natural gas.
Dry desulfurization and denitrification equipment manufacturers indicate that the core products of dry, ammonia-free, low-temperature desulfurization and denitrification integrated technology are low-temperature oxidation catalytic materials, trade name: desulfurization catalyst, code: HYS-1001; denitrification catalyst, code: HYN-1102; integrated desulfurization and denitrification catalyst, code: HYSN-1203.
It has the following characteristics:
Innovation: Dry desulfurization-ammonia-free low-temperature catalytic denitrification integrated technology is a new dry, low-temperature desulfurization and denitrification method.
Dry method: No water is consumed, and no wastewater is produced, and the chimney will not produce a large amount of water vapor emission.
Clean: Dry desulfurization-ammonia-free low-temperature catalytic denitrification integrated technology has no wastewater, waste gas, or waste residue emissions.
Low energy consumption: Energy consumption is very low.
Compatibility: It can be used to treat almost all flue gas treatment conditions, such as coal combustion, gas combustion, coking, and sintering.
High efficiency: No heating or pressurization is required, and high-efficiency removal can be achieved at room temperature to 300℃.
The company mainly produces various dust removal, desulfurization, denitrification, VOCs waste gas purification, wastewater treatment, noise reduction, complete sets of industrial electrical control systems and equipment, and researches and develops waste gas, wastewater, waste residue, and noise treatment equipment.
