Embodiment 1

[0025] Such as figure 1 As shown, the reverse-rotation vortex purification tower of the present invention includes a purification tower 1, an original flue gas inlet 2, a reverse-rotation vortex purifier 3 installed under the partition plate 4, a nozzle 5, a mist eliminator 6, and a smoke cleaner Gas outlet 7, slurry tank 8, slurry circulation pump 9, absorbent inlet 10, oxidation air inlet 11, by-product recovery slurry outlet 12 and spray pipe network 13.

[0026] On the purification tower 1, a net flue gas outlet 7, a mist eliminator 6, a nozzle 5 and a slurry tank 8 are sequentially arranged from top to bottom, and a reverse-rotation vortex purifier 3 is arranged between the nozzle 5 and the slurry tank 8 . The counter-rotating vortex purifier 3 is connected to the purification tower 1 through a partition 4 . One side of the purification tower 1 is provided with a raw flue gas inlet 2, a slurry circulation pump 9, an absorbent inlet 10, an oxidation air inlet 11 and a by...

Embodiment 2

[0030] In the anti-rotation vortex purification tower of the present invention, except that the included angles between the guide vanes 33 and the horizontal plane in each channel are the same, the included angles are 20°-40°, and the positions and connections of other components are the same.

Embodiment 3

[0032] The counter-rotating vortex purification tower of the present invention decreases successively from the outer passage 38 to the inner passage 37 of the central short pipe 34, and the angle decreases by 1.5° for each passage inward, and the positions and connections of other components are the same.

[0033] The working principle of the foregoing embodiment is as follows:

[0034] In practical application, the raw flue gas enters the purification tower 1 through the raw flue gas inlet 2, and flows from bottom to top. In the slurry tank 8 , the counter-rotating vortex cleaner 3 is installed under the partition 4 . After the flue gas enters the purification tower 1, from the slurry surface of the slurry tank 8 to the bottom surface of the counter-rotation vortex purifier 3, the flue gas is in this area, mainly by the contact of the slurry flowing out of the counter-rotation vortex purifier 3. The primary purification of the air is performed, and its effect is similar to t...

Abstract

The invention relates to a purification tower for purifying coal-fired boiler smoke, in particular to an anticyclonic vortex purification tower. A plurality of anticyclonic vortex purifiers are installed in the anticyclonic vortex purification tower. For each anticyclonic vortex purifier, an outer barrel, a central short pipe and a plurality of inner barrels form a plurality of isometric circular-ring-shaped channels, a plurality of guide vanes are arranged in each channel, the installation angles of the guide vanes in the adjacent channels are opposite, and rightward and leftward anticyclonic airflow directions are formed. When flowing through the purification tower at the same time, smoke and slurry pass through a spraying field purification section, an efficient mass transfer field purification section and a mixed flow purification section, and the purpose of efficiently purifying smoke is achieved. The purification tower has the advantages that the single purifiers are large in smoke treatment capacity, high in purification efficiency and stable and reliable in operation, and operation and management are convenient; the purification tower is simple in structure, low in project cost, small in water circulation amount, good in power saving effect and low in operation cost.

Description

technical field [0001] The invention relates to a purification tower for purifying flue gas of a coal-fired boiler, in particular to a counter-rotating vortex purification tower. Background technique [0002] Sulfur dioxide, NO in flue gas from coal-fired boilers X , Smoke and dust have caused serious pollution to China's environment, seriously affecting people's lives and health, and causing great losses to the national economy. In order to change the situation, China's relevant departments continue to introduce some policies and regulations, and continue to introduce some new technologies from abroad; many domestic scientific research institutions and industry insiders with technology research and development capabilities have been exploring the development of high purification rate, energy saving, and low investment. , low operating cost, flue gas purification technology and equipment suitable for my country's national conditions. The single-cylinder swirling plate purif...
