Quality appraisal of desulfurization equipment

desulfurization equipment is to convert SO2 in flue gas into solid or liquid form, or into a gaseous state that can be easily separated to reduce environmental pollution. Such devices are particularly common in the power industry because they effectively prevent environmental pollution caused by SO2 generated when burning coal. There are many types of desulfurization equipment, including but not limited to desulfurization towers, side-entry mixers, flue gas desulfurization equipment, etc. The selection and application of
desulfurization equipment depends on specific industrial needs and environmental protection standards. They play an important role in protecting the environment and reducing sulfur oxide emissions.
In the case of desulfurization equipment quality appraisal, Zhongke Testing can provide desulfurization equipment quality appraisal services.

1. Equipment performance: including desulfurization efficiency, energy consumption, operation stability, etc. Equipment performance can be evaluated against relevant national or local standards.
2. Equipment material: Desulfurization equipment needs to withstand the erosion of corrosive gases, so its material needs to be made of materials with good corrosion resistance, such as acid and alkali-resistant stainless steel, fiberglass, etc. For the identification of equipment materials, material composition analysis and physical performance testing can be performed.
3. Equipment structure: The structure of desulfurization equipment plays an important role in its operational stability, cleaning and maintenance. Simulation analysis, detection and inspection of equipment structures can be carried out, such as checking whether equipment interfaces, brackets, etc. are strong.
4. Environmental protection indicators: Desulfurization equipment needs to meet relevant national and local environmental protection indicators, such as emission concentration, total emissions, etc. The operation of the equipment can be monitored and tested to confirm that it meets relevant environmental protection indicators.
5. Equipment management: The management of desulfurization equipment is also very important, including equipment operation log records, maintenance status, etc. Assessment and identification can be made based on the management situation.

After the completion of the boiler desulfurization project tendered by a thermal power company, due to various reasons, the overall equipment operation was abnormal twice, resulting in the equipment being unable to be delivered for use. And because the boiler's sulfur dioxide concentration exceeded the standard and failed to meet the environmental protection department's acceptance requirements, it was fined. The thermal power company then had a dispute with the equipment manufacturer.
was entrusted by the court to conduct appraisal and analysis on "whether there are quality problems" in the boiler desulfurization project involved.
identification and analysis results: The
identification and analysis expert group discussed the relevant information and on-site investigation of the desulfurization equipment involved and conducted a comprehensive quality and technical analysis, and made the following suggestions and conclusions: The sulfur dioxide emission concentrations of
1#, 2#, 3#, and 4# desulfurization system equipment all meet the requirements of the "Technical Agreement". The case involved 14 unqualified items and 4 safety hazards in the desulfurization equipment.
