Problems solved by technology

By burning coal sulfur in power plants, 100% gypsum should be generated, but the actual is 46%, and gaseous SO is emitted 2 Only 0.22%, the real desulfurization efficiency only reaches 50%, and the imbalance of total sulfur intake and discharge is the key to the formation of gypsum rain and the largest source of airborne PM2.5 particles; therefore, the current wet desulfurization technology is not perfect

Embodiment

[0044] Example: 300,000 units, 1,080-ton boiler.

[0045] Flue gas flow: 1.2 million cubic meters per hour.

[0046] After dust removal, the smoke concentration is greater than 400mg / m 3 .

[0047] After dedusting, the flue gas at about 150 degrees enters the desulfurization tower through the fan.

[0048] Effect: Discharge colorless and transparent flue gas from the top of the electrostatic tower, the demisting efficiency is close to 100%, the dust removal efficiency is close to 100%, the soot emission concentration is less than 5 mg / m3, and the gaseous SO 2 The removal efficiency is close to 100%, SO 2The emission concentration is less than 10 mg / m3.

Abstract

The invention belongs to the technical field of environmental protection equipment and particularly relates to wet desulfurization equipment for a coal fired boiler. The wet desulfurization equipment for the coal fired boiler has a very good desulfurization effect, comprises a desulfurization tower and is structurally characterized in that a spray tower is arranged at the upper end of the desulfurization tower, an electrostatic tower is arranged at the upper end of the spray tower, a circulating pool is arranged at the lower end of the desulfurization tower and connected with an inlet of a first circulating pump through a pipeline, an outlet of the first circulating pump is connected with an inlet of a spray oxidation pipe at the spray oxidation part through a pipeline, and an output end, for a liquid after spray oxidation, of the spray oxidation part is connected with inside of the circulating pool; a concentration tank is connected with an inlet of a second circulating pump through a pipeline, an outlet of the second circulating pump is connected with an inlet of a spray pipe, one part of an outlet of the spray pipe is arranged at the upper part of the spray tower, and the other part of the outlet of the spray tower is arranged at the upper part of the desulfurization tower; a transverse smoke inlet is formed in the lower part of the desulfurization tower.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a coal-fired boiler wet desulfurization equipment. Background technique [0002] In May 2014, the coal-fired flue gas dust removal and desulfurization integrated process and equipment appraisal meeting hosted by Professor Wang Wenxing, academician of the Academy of Engineering, and National Environmental Advisor Professor Zhu Tan pointed out that: the current desulfurization equipment, the smoke and dust emission concentration is greater than 50mg / m 3 , gaseous SO 2 Emission concentration greater than 100mg / m 3 , the pH of the recovered fog droplets is 2.6, indicating that the current discharge of mist smoke is a major pollutant; it is not water vapor, but acid. By burning coal sulfur in power plants, 100% gypsum should be generated, but the actual is 46%, and gaseous SO is emitted 2 Only 0.22%, the real desulfurization efficiency is only...
