Sintering desulfurization and white smoke removal system and technological process of sintering desulfurization and white smoke removal system

Abstract

The invention discloses a sintering desulfurization and white smoke removal system and a technological process of the sintering desulfurization and white smoke removal system, which can be used for mainly solving the problems that a method for treating 'white smoke' is high in energy consumption, cannot achieve energy conservation and emission reduction, and the like in the prior art. The sintering desulfurization and white smoke removal system comprises a desulfurization tower (3) and a smoke discharging chimney (1) arranged at the top of the desulfurization tower (3). The sintering desulfurization and white smoke removal system is characterized by also comprising a dehumidifying system connected with the smoke discharging chimney (1), wherein a flap valve (2) used for switching a communicating state of the smoke discharging chimney (1) and the dehumidifying system is also installed on the smoke discharging chimney (1) and positioned above the joint of the smoke discharging chimney (1) and the dehumidifying system. According to the sintering desulfurization and white smoke removal system and the technological process, the desulfurization treatment is firstly carried out, then three-step gradually strengthened dehydration treatment is carried out, and finally cooling treatment is carried out, so that flue gas can be effectively dehumidified, and the energy consumption of the sintering desulfurization and white smoke removal system is greatly reduced due to the technology of firstly dehydrating and then cooling.

Description

technical field [0001] The invention belongs to the technical field of energy saving and emission reduction, and specifically relates to a sintering desulfurization and white smoke removal system and a process flow thereof. Background technique [0002] With the rapid development of my country's economy, the relative shortage of energy and resources has become the bottleneck of economic development. How to make reasonable use of existing precious resources is the key to ensure the sustainable development of my country's economy. For this reason, the State Council pointed out in the "Comprehensive Work Plan for Energy Conservation and Emission Reduction" that by 2015, China's GDP energy consumption will drop from 1.22 tons of standard coal in 2010 to below 1 ton of standard coal, a reduction of about 25%; The water consumption of industrial added value is reduced by 30%; the total discharge of major pollutants is reduced by 10%. Energy saving and emission reduction has beco...

AI Technical Summary

Problems solved by technology

Among them, the dry dehumidification technology requires repeated heating of the dehumidification equipment, which has high energy consumption. The purpose of dehumidification and treatment is achieved through high energy consumption, and there is no waste heat recovery process in the treatment process, which wastes heat energy resources and does not meet the requirements of energy conservation. ; Freezing and dehumidification technology requires the application of large-scale refrigeration equipment. Due to the large amount of "white smoke", the cold water consumption of large-scale refrigeration equipment is high, and there is no waste heat recovery process in the treatment process, which does not meet the requirements of energy saving and water conservation. ; Filtration and dehumidification technology needs to replace the filter equipment at any time, the area of ​​the filter is too large, the consumption is high, there is no heat recovery, and it does not meet the requirements of energy saving

[0004] In summary, in the prior art, the "white smoke" treatment process has the defects of high energy consumption and no waste heat recovery
