Embodiment Construction
[0028] The present invention will be further described below in conjunction with accompanying drawing.
[0029] Such as Figure 1 ~ Figure 4 The shown microporous plate water film dust collector of the present invention includes a cylindrical shell 1, a smoke inlet 2 arranged on the side wall of the cylindrical shell and a smoke outlet 3 arranged on the top of the cylindrical shell . The top of the cylindrical shell 1 is a generally trumpet-shaped channel whose cross-section gradually decreases from bottom to top. The lower end of the channel is connected to the cylinder body, and the upper end is connected to the smoke outlet. The bottom of the cylindrical shell is a trumpet-shaped ash collecting hopper 4 whose cross section gradually decreases from top to bottom.
[0030] The inner cavity of the cylindrical housing 1 is provided with a water supply plate 11 , a microporous plate, a water collection tank 14 and an even distribution plate 15 . Such as figure 2 As shown, t...

Abstract
The invention discloses a microporous plate type water-film dust remover. The microporous plate type water-film dust remover comprises a cylindrical shell, a flue gas inlet formed in the lateral wall of the cylindrical shell and a flue gas outlet formed in the top of the cylindrical shell, wherein a water supply plate, a microporous plate, a water collecting tank and a uniform distribution plate are arranged in the inner cavity of the cylindrical shell, the microporous plate is horizontally fixed in the central area of the inner cavity of the cylindrical shell, the water supply plate is located between one side, away from the flue gas inlet, of the microporous plate and the inner wall of the cylindrical shell and provided with a water supply pipe, the water collecting tank is located on one side, close to the flue gas inlet, of the microporous plate, the water inlet of the water collecting tank is connected to the edge of the microporous plate, the uniform distribution plate obliquely extend from the water outlet of the water collecting tank outwardly and downwardly to allow the water flow overflowing out of the water collecting tank to form a water curtain, and the flue gas inlet directly faces the water curtain. The microporous plate type water-film dust remover has the advantages that overflow water curtain film dust removing and porous plate surface water-film dust removing are combined, and high removing efficiency on the particles, especially the fine particles with the particle size larger than 2.5 micrometers in flue gas can be achieved.
Description
technical field [0001] The invention mainly relates to the technical field of flue gas pollutant treatment, in particular to a microporous plate type water film dust collector. Background technique [0002] At present, water film dust collectors based on centrifugal wet dust removal technology are widely used in small and medium-sized boilers and kilns because of their simple structure, good selectivity, stable operation, and convenient maintenance. The working principle of this technology is that the dust-laden airflow enters the dust collector tangentially and forms a high-speed rotating airflow. The dust in the airflow is thrown to the inner wall of the dust collector under the action of centrifugal force and is taken away by the water film flowing from top to bottom on the inner wall of the dust collector. , to complete the flue gas dedusting process. [0003] However, due to the constraints of equipment structure, working mechanism and other factors, some potential pro...
