For the operation and maintenance of the wet electrostatic precipitator, strict management systems and operating procedures should be formulated. The equipment must be managed by full-time personnel, who should conduct regular inspections and record the operation status of the wet electrostatic precipitator. Operators need to record the operating parameters of the equipment every hour, including flue gas temperature, insulation chamber temperature, primary voltage, primary current, secondary voltage, secondary current, and the operation status of the fan, etc.

Operation and Maintenance of Wet Electrostatic Precipitators

The 8# calcium chloride flue gas treatment wet electrostatic precipitators produced by our company has started commissioning and is ready to be put into use.

The flue gas volume of this equipment is 50,000 m³/h, the flue gas temperature is ≤ 50℃, the flue gas does not contain flammable and explosive gases, the air flow direction is bottom-in and top-out type, the wet electrostatic precipitator body is independently installed on the steel frame, and the equipment operates under positive pressure.

This is already the fourth calcium chloride tail gas treatment equipment produced by our company for customers. Customers in need are welcome to call for consultation.

The bag dust collector of the flue gas pretreatment device for the yellow phosphorus tail gas 100t/h high-temperature and high-pressure gas-fired boiler (540℃, 9.8MPa) operates stably.

This device uses sodium carbonate (Na?CO?) as the flue gas treatment agent, and a bag dust collector is used for dust removal. The flue gas pretreatment device consists of four parts: a raw material bin, a feeding system, a mixing and drying system, and a bag dust collector. In this project, the content of sulfur, phosphorus and other acidic substances in the flue gas is relatively high. The flue gas pretreatment device needs to fully consider the corrosion problem caused by sulfur, phosphorus and other acidic substances. All flues in the flue gas pretreatment device are made of materials not lower than 2205 and 316L.

The flue gas pretreatment device consists of four parts: a raw material bin, a feeding system, a mixing and drying system, and a bag dust collector.

Boiler flue gas in cane sugar refineries is generally characterized by high moisture content and high dust density. For the treatment of such flue gas, the gritstone water film demisting technology can be adopted. It is a wet demisting process based on gritstone, configured as a "vertical/horizontal Venturi + cyclone water film/cyclone plate demister". This technology boasts advantages such as low investment, simple maintenance and long service life. Flue gas treated by this technology could basically meet the previous old emission standards; however, with the upgrading of emission requirements to the current new standards, this technology can no longer satisfy the existing compliance criteria.

At present, three technologies are worthy of exploration, namely bag-type demisting technology, electrostatic-bag hybrid demisting technology and wet electrostatic precipitator technology. Each of these three demisting technologies has distinct advantages: bag-type and electrostatic-bag hybrid demisting technologies feature high demisting efficiency, but they entail high operating costs and have a short service life. In contrast, wet electrostatic precipitator technology is highly practical and easy to operate, yet it needs to be combined with other technologies to exert its optimal performance. The better the water droplet atomization effect and the larger the dust particles, the more prominent the final treatment outcome will be.
