AI Technical Summary

Technical Problem

In the prior art, the flue gas is humid after treatment, and the heat in the flue gas is directly lost, resulting in waste of resources.

Method used

A flue gas purification device for thermal power plants is designed, including pretreatment components, spray components, partition networks and water network circulation components. The pretreatment assembly is used to intercept large particulate impurities and use flue gas heat to dry humid gas, the spray assembly and partition network are used for further desulfurization, denitrification and dust settlement treatments, and the water network circulation assembly is used to increase the contact area between the flue gas and the treatment solution.

Benefits of technology

It effectively reduces the humidity of flue gas and uses the heat of flue gas to dry, prevents moisture from entering the external environment directly, and improves the purification effect of flue gas and reduces waste of resources.

Abstract

The invention provides a flue gas purification device for a thermal power plant. The flue gas purification device comprises a main treatment box and a pretreatment assembly. The pretreatment assembly is used for conducting primary treatment on flue gas of the thermal power plant and utilizing flue gas waste heat. The spraying assembly is mounted at the main treatment box, and the spraying assembly is used for performing circulating spraying operation on the treatment solution in the pretreatment assembly; the separation net is mounted on the inner wall of the main treatment box and is used for filtering the flue gas of the thermal power plant; the water net circulating assembly is arranged above the separation net, and the water net circulating assembly is used for distributing a circulating water curtain on the separation net. The thermal power plant flue gas can be pretreated through the pretreatment assembly, large-particle impurities carried in the thermal power plant flue gas are intercepted, meanwhile, the heat of the flue gas at the pretreatment assembly can be used for drying wet gas obtained after spraying purification, the heat in the flue gas can be utilized, and the heat utilization rate of the flue gas is improved. And meanwhile, gas with relatively high humidity can be prevented from directly entering the external environment.
