The invention discloses a high-efficient purifying device for flue gas of a coal-fired power plant and a use method thereof. The high-efficient purifying device comprises a first purifying tank and a second purifying tank, wherein a supporting plate is arranged in the first purifying tank; a through hole is formed in the supporting plate; a gas inlet pipe and a feeding gate are arranged on one side of the first purifying tank away from the second purifying tank; an oxidation air blower is arranged on the gas inlet pipe; a separating plate is arranged in the second purifying tank; the second purifying tank is divided into a left tank chamber and a right tank chamber by the separating plate; a gas baffle is arranged in the right tank chamber; the first purifying tank is communicated with the second purifying tank through a gas pipe; one end of the gas pipe away from the first purifying tank is bent and extended into the right tank chamber. The high-efficient purifying device for the flue gas of the coal-fired power plant has the advantages that the flue gas is more safely purified, the purifying efficiency of the flue gas is increased, the purifying degree of the flue gas is greatly increased, the flue gas is completely purified, the time of purifying the flue gas is shortened and the working efficiency is greatly increased.
Description
technical field [0001] The invention relates to the technical field of industrial environmental protection, in particular to a high-efficiency purification device for flue gas in a coal-fired power plant and a method for using the same. Background technique [0002] In recent years, my country's power generation still uses coal as the main fuel. Due to problems such as insufficient coal combustion, the chimneys of coal-fired boilers emit a large amount of dust and sulfide flue gas. These flue gases are directly discharged into the atmosphere, polluting the air. , affecting the life safety of human beings, animals and plants. Although there are many kinds of treatment devices at present, their purification is not complete and the purification efficiency is not high enough. Need a kind of novel technical scheme to solve the above-mentioned problem now. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-efficie...
