Embodiment Construction

[0019] A high-efficiency electro-hydraulic dedusting method for dusty flue gas, the key is: the method includes the following steps:

[0020] a. Apply a negatively charged electrostatic field to the flue gas to form negatively charged flue gas;

[0021] b. Pass the negatively charged flue gas into the positively charged filtrate, and use the positive and negative charges to attract and remove the smoke in the flue gas.

[0022] In the step b, the negatively charged flue gas is passed into the positively charged filtrate, and the specific method is to send the negatively charged flue gas vertically upward into the turbulence generating device 3 through the fan 1, and filter The liquid flows down from the top of the turbulent flow generating device 3, and the filtered liquid is subjected to the upward pressure conveyed by the fan to form a suspended water wave that oscillates up and down repeatedly. During the oscillation process, the positively charged dust in the flue gas is a...

Abstract

An efficient electro-hydraulic dust removal method and system for dust-containing flue gas solve the technical problem of how to more effectively remove hydrophobic dust particles in wet dust removal, and adopt the technical scheme that the method comprises the following steps: a, applying a negative charge electrostatic field to flue gas to form flue gas with negative charges; and b, introducing the flue gas with negative charges into the filtrate with positive charges, and removing smoke dust in the flue gas by utilizing positive and negative charge attraction. A negative electric field is applied to flue gas to be treated through the electrostatic ion wind generating device, so that smoke dust is negatively charged, and different from an electrostatic dust collection device in the prior art, the electrostatic dust collection device is used for directly adsorbing and collecting dust with static electricity. Meanwhile, the defects of electrostatic adsorption dust removal and wet dust removal are overcome, dust in flue gas can be efficiently adsorbed, and the dust removal rate can reach 97%.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and dust removal, and relates to an electro-hydraulic dust removal method and system, in particular to a high-efficiency electro-hydraulic dust removal method and system for dusty flue gas. Background technique [0002] At present, in the field of dust removal technology, mechanical dust removal, electric dust removal, filter dust removal, and washing dust removal are mainly used, and each method has advantages and disadvantages. Among them, washing dust removal belongs to wet dust removal, and the rest belongs to dry dust removal. Wet dedusting equipment requires less investment and has a relatively simple structure; the purification efficiency is high, and dust particles above 0.1 μm can be removed; the equipment itself generally has no moving parts, and if the quality of the manufacturing material is good, it is not easy to break down. The more prominent advantage is that it a...
