Comprehensive flue gas synergistic treatment system for ceramic industry

Abstract

The invention discloses a comprehensive flue gas synergistic treatment system for the ceramic industry. The system comprises a desulfurizing tower, a bag-type dust collector, a slaked lime supply device, a water spraying device, a recirculation device and an induced draft fan; a gas inlet is formed in the bottom end of the desulfurizing tower; an exhaust port is arranged at the top end of the desulfurizing tower; the slaked lime supply device and the water spraying device are communicated with the bottom of the desulfurizing tower; the communication position of the water spraying device and the desulfurizing tower is higher than the communication position of the slaked lime supply device and the desulfurizing tower, the bag-type dust collector is communicated with the exhaust port of the desulfurizing tower; the induced draft fan is communicated with the bag-type dust collector; one end of the recirculation device is connected with the bottom end of the bag-type dust collector, and theother end of the recirculation device is connected with the bottom of the desulfurizing tower, so that slaked lime can react with corresponding components of SO2 in flue gas, and therefore, desulfurization can be realized; the water spraying device is arranged, so that a good reaction environment in the desulfurizing tower is guaranteed; the recirculation device is arranged, particles are returned to the desulfurizing tower for continuous reaction, sufficient desulfurization of discharged materials is guaranteed, ultra-low emission without waste water and obvious plume is achieved, and the purpose of environmental protection is achieved.

Description

technical field [0001] The invention belongs to the field of dust removal and desulfurization equipment, and in particular relates to a comprehensive flue gas collaborative treatment system in the ceramic industry. Background technique [0002] With the development of society, people's awareness of environmental protection is getting stronger and stronger, and the country's efforts to protect the environment are increasing, and the country's industrial waste gas emission standards are also higher; therefore, the existing waste gas emission treatment requirements are also higher, especially For ceramic manufacturing enterprises, the requirements for exhaust gas emission are stricter, and the sulfur content in the exhaust gas is strictly controlled. However, when some existing desulfurization equipment treats industrial waste gas, the gas is quickly discharged through the desulfurization tower, and the desulfurization rate is low, so that the sulfur content of the gas finally ...

AI Technical Summary

Problems solved by technology

However, when some existing desulfurization equipment treats industrial waste gas, the gas is quickly discharged after passing through the desulfurization tower, and the desulfurization rate is low, so that the sulfur content of the gas finally discharged into the atmosphere is relatively high, which has an impact on the atmospheric environment

Moreover, some exhaust gases also contain NOx, which will also cause pollution if they are directly discharged into the air.
