Description

Technical Field

[0001] This utility model relates to the field of desulfurization technology in thermal power plants, and specifically discloses a rapid desulfurization device for thermal power plants. Background Technology

[0002] Existing thermal power plants utilize the energy generated by burning coal during operation. However, the combustion of coal produces a large amount of flue gas containing sulfur, nitrates, and dust. If these are directly released into the atmosphere, they will cause significant environmental pollution. Therefore, thermal power plants install equipment to purify the sulfur and nitrates in the flue gas.

[0003] Chinese patent CN214130739U discloses a rapid desulfurization device for thermal power plants. However, the above patent has certain shortcomings in its use. Although it can disassemble and replace the dustproof plate, it does not have the function of recycling the absorbent during desulfurization, thus causing a waste of resources. Therefore, we propose a rapid desulfurization device for thermal power plants to solve the above problems. Utility Model Content
