Dry desulfurization is an environmentally friendly technology commonly used in industrial waste gas treatment. It is mainly used for flue gas desulfurization emitted by coal-fired boilers, waste incinerators, cement plants, steel plants, etc. The following is a product introduction and main features of dry desulfurization:
★Introduction to dry desulfurization products
Dry desulfurization refers to the process of removing acidic gases such as sulfur dioxide (SO₂) from flue gas by reacting with solid desulfurizers (such as lime, calcium hydroxide, calcium carbonate, activated carbon, dry desulfurizer, etc.) without using liquid absorbents. Common systems include bag filter + reactor structure, which can also be used in conjunction with activated carbon adsorption, powder spraying and other technologies.
Mainly applicable to:
Small and medium-sized coal-fired boilers
Waste incineration stations
Cement rotary kilns
Lime kilns
Metallurgical industry, etc.
★Product features
1. Simple system structure and low investment cost
No liquid circulation system and sewage treatment equipment are required, the construction period is short, and the operation and maintenance are simple.
2. No wastewater discharge, environmentally friendly
Complete dry reaction, no need to discharge wastewater, reduce secondary pollution, and meet green environmental protection requirements.
3. Easy operation and maintenance
The equipment runs stably, has a high degree of automation, and has a small daily maintenance workload.
4. Strong adaptability
It can adapt to a variety of fuels (coal, garbage, petroleum coke, etc.) and complex flue gas components, and is especially suitable for intermittent or small-scale production units.
5. Dust removal and desulfurization are carried out simultaneously
Desulfurization and dust removal are usually completed by the same set of equipment (such as bag dust collector), which improves the overall efficiency of the system and saves space and cost.
6. Moderate desulfurization efficiency
The desulfurization efficiency is generally 70%~90%, which is particularly suitable for occasions with low SO₂ concentration (such as small boilers).
7. By-products are easy to handle
The product is a dry powder (such as CaSO₄, CaSO₃), which can be used as building materials and partially realize resource utilization.
★Common dry desulfurization processes
Process type absorbent characteristics
Solid injection method lime and limestone powder are suitable for small and medium-sized boilers, with low investment
Reaction tower method dry composite desulfurizer combined with bag dust removal, high efficiency
Activated carbon adsorption method activated carbon and activated coke have both desulfurization and denitrification, suitable for low-temperature flue gas

★FAQ

Q. How high is the dust removal efficiency of bag filters?
A. The dust removal efficiency can generally reach more than 99%, and can effectively filter fine dust above 0.3 microns.

Q. Can bag filter handle high temperature gas?
A. It can handle high temperature gas up to about 250℃. It needs to use high temperature resistant filter material and control the temperature and humidity of the gas.

Q. How to extend the service life of bag filter?
A. Choose appropriate filter material, clean dust on time, avoid high temperature shock and dust blockage, and perform regular inspection and maintenance.
