Smoke purifier for boiler

Abstract

The invention discloses a smoke purifier for a boiler. The smoke purifier comprises a base, a boiler heat exchanger and an absorption and purification tower, the boiler heat exchanger and the absorption and purification tower are mounted on the base, an input end of the boiler heat exchanger is connected with a boiler flue while an output end of the same is connected with a smoke inlet at the bottom of the absorption and purification tower, the absorption and purification tower comprises an electrostatic dedusting chamber, a spray cavity and a filter chamber sequentially from top to bottom, a smoke outlet is arranged at the top of the absorption and purification tower, a plurality of spray heads are arranged in the spray cavity, each spray head is connected with a spray pipeline, multiple pipelines are arranged in the filter chamber, and a plurality of fiber balls are arranged in each pipeline. The smoke purifier has the advantages that the smoke purifier is simple in structure and convenient and quick to use and operate, smoke is gradually purified by means of filtering through the fiber balls, electrostatic dedusting and spraying, content of dust in smoke after being purified is lowered effectively, and purifying effect is remarkable; the smoke purifier is easy to realize backwash, convenient to clean and high in operability, a tower wall is less prone to corrosion, and cost investment is lowered.

Description

technical field [0001] The invention relates to a purifier, in particular to a flue gas purifier for a boiler. Background technique [0002] Smoke is a mixture of gas and smoke and is the main cause of air pollution. In industrial production, industrial flue gas must be purified before being discharged or recycled. When dealing with high-temperature flue gas, especially boiler flue gas, sometimes the temperature of the flue gas is as high as several hundred degrees, which may cause the cleaning and purification equipment to be heated and worn, resulting in a large investment in equipment maintenance costs and poor economic benefits. [0003] At present, fiber balls have been widely used in the field of purification due to their outstanding advantages such as fast filtration speed, large sewage interception capacity and good filtration effect. However, in actual use, when the flue gas flow and pressure fluctuate, the fiber ball will shake. The shaking of the fiber ball wil...

AI Technical Summary

Problems solved by technology

But in actual use, when the flue gas flow and pressure fluctuate, the fiber ball will shake

The shaking of the fiber ball will easily cause the fiber ball to wear and tear, making the fiber ball unable to work normally, and in severe cases, the entire purification equipment will not work normally

Moreover, the purification effect of traditional purification equipment is average, the equipment structure is complex, and the energy consumption is large, which is difficult to meet the modern concept of green environmental protection.
