Description

Technical Field

[0001] The present invention relates to the technical field of flue gas whitening, and specifically to a flue gas whitening system and device. Background Art

[0002] With the increasingly strict environmental protection regulations, the phenomenon of white smoke in industrial flue gas emissions has received wide attention. The white smoke is mainly caused by the condensation of water vapor in wet flue gas to form tiny water droplets in a low-temperature environment, resulting in visual pollution and environmental problems. Especially in wet flue gas treatment processes such as desulfurization and denitrification, after the flue gas passes through the scrubber tower, the temperature decreases and the water vapor content increases, and white smoke is extremely likely to form when directly discharged. Therefore, developing efficient and energy-saving wet flue gas whitening technologies has become an important research direction in the current environmental protection field.

[0003] The flue gas whitening device is an environmental protection equipment specifically used for treating wet flue gas, and its importance is mainly reflected in the treatment of wet flue gas formed after flue gas desulfurization. However, the existing flue gas situation is as follows: The high-temperature flue gas from the boiler or production line enters the desulfurization tower or scrubber tower, undergoes desulfurization or scrubbing, then enters the upper space of the reactor, and is then subjected to demisting treatment by the demister in the upper part of the reactor. Finally, the flue gas enters the chimney and is discharged into the atmosphere. Such a whitening effect is poor, and only a small part of the moisture can be removed; in addition, some additional manufacturers add some whitening technologies, and these whitening methods mostly adopt direct heating or dilution methods, which have problems such as high energy consumption, low efficiency, and resource waste. In view of the above situation, the present invention provides a flue gas whitening system and device to solve the above problems. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a flue gas whitening system and device, which solves the problems that the existing high-temperature flue gas enters the desulfurization tower or scrubber tower, undergoes desulfurization or scrubbing, then enters the upper space of the reactor, and is then subjected to demisting treatment by the demister in the upper part of the reactor. Finally, the flue gas enters the chimney and is discharged into the atmosphere, resulting in a poor whitening effect and only being able to remove a small part of the moisture; in addition, some whitening technologies mostly adopt direct heating or dilution methods, which have problems such as high energy consumption, low efficiency, and resource waste.

Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] By providing a flue gas de - whitening system and device in the embodiments of the present application, the problems are solved that the existing high - temperature flue gas enters the desulfurization tower or washing tower, is desulfurized or washed, then enters the upper space of the reactor, and the mist droplets are removed by the demister at the upper part of the reactor. Finally, the flue gas enters the chimney and is discharged into the atmosphere. In this way, the de - whitening effect is poor and only a small part of the moisture can be removed. In addition, some existing de - whitening technologies mostly adopt direct heating or dilution methods, which have problems such as high energy consumption, low efficiency, and resource waste.

[0040] Desulfurization washing and primary demisting module: The high - temperature flue gas is subjected to wet desulfurization treatment through a flue gas desulfurization tower, and then the high - temperature wet flue gas is preliminarily demisted through the demister at the top, so that most of the sulfides in the high - temperature flue gas are washed, and at the same time, the flue gas particles and mist droplets in the demisted high - temperature wet flue gas reach a better water content.

[0055] Embodiment III

[0056] According to the appendix Figures 2-6 as shown

[0057] Inside the whitening elimination cylinder 1, there is a flue gas whitening elimination mechanism 4 and a conditioning and filtering element 5. The flue gas whitening elimination mechanism 4 includes a cooling water spray head 42, a stirring fan blade 45, a cleaning part 46 and an inclined baffle 47. The cooling water spray head 42 is rotatably connected inside the whitening elimination cylinder 1 and is used for evenly spraying the cooling liquid.

The cleaning part 46 is rotatably connected inside the whitening elimination cylinder 1 and is used for cleaning the conditioning and filtering element 5. The inclined baffle 47 is fixedly connected to the bottom end of the cleaning part 46.

The high-pressure spray head 461 is used for spraying cleaning water onto the conditioning and filtering element 5. A brush 471 is fixedly connected to the bottom end of the inclined baffle 47.

The fine filter mesh plate 51 is used to further increase the contact area between the flue gas and its surface, so that the water mist in the flue gas is more likely to condense into water droplets and adhere to the fine filter mesh plate 51 when passing through the fine filter mesh plate 51, resulting in a large amount of water droplets adhering to the fine filter mesh plate 51. These water droplets further capture the small molecular particles in the flue gas and often leave some dirty water droplets on the fine filter mesh plate 51, leading to the blockage of the fine filter mesh plate 51, thus preventing the flue gas from passing through. Therefore, the fine filter mesh plate 51 is rotatably connected to the coarse filter mesh plate 52 and connected by the spring 523, so that the fine filter mesh plate 51 will vibrate under the pressing of the inclined block 47, shaking the water droplets off the fine filter mesh plate 51, and making the contact area between the water line sprayed by the high-pressure nozzle 461 and the fine filter mesh plate 51 larger through the inclination, better cleaning the fine filter mesh plate 51.

[0061] The flue gas and the coolant are fully and strongly mixed through the conditioning filter element 5 to minimize the heat exchange distance and obtain the intensity of heat exchange and the particulate washing effect to the greatest extent.
