Problems solved by technology

Since membrane filtration relies on the "surface filtration" of the membrane layer to achieve high precision and high efficiency, an electric field is formed on the outer surface of the ceramic membrane, and the use of Coulomb force to strengthen the removal of dust may cause small particles to enter the pores of the membrane layer and deposit under the action of the electric field force. Blockage occurs, or the phenomenon that the filter cake outside the membrane layer is difficult to be removed due to the Coulomb force

Abstract

The invention relates to a pulse charge intensification-filtration catalysis integrated flue gas purification device and a method.The device comprises a gas inlet flue, a flue pulse discharger, a catalysis and filtration integrated reactor and a gas outlet flue; the gas inlet flue is arranged on the lower middle portion of the catalysis and filtration integrated reactor, the flue pulse discharger is arranged in the gas inlet flue, and an ash hopper, a flue gas turbulence device, a catalytic filter pipe, a blowback air pipe and a top catalytic reaction layer are respectively arranged in the catalysis and filtration integrated reactor from bottom to top. The invention further provides a flue gas purification method using the device, and the flue gas purification method comprises the steps of (1) pulse charging, (2) coagulation, (3) filtration catalysis and (4) NH3 decomposition. The flue gas purification device has the advantages that PM2.5, NOx, VOCs, heavy metal mercury and other pollutants can be removed at the same time, filtration resistance is reduced, membrane holes are prevented from being blocked, NH3 escape is effectively controlled, and the ultra-low emission and environment-friendly emission requirements are met.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an integrated flue gas purification device and method of pulse charging enhancement-filtration and catalysis. [0002] technical background [0003] With the completion of the ultra-low emission transformation of the coal power industry, the non-power industry will become a key area of ​​air pollution control in the future. Major non-electric industries such as steel, glass, and coking will emit a large amount of dust and NO x , due to the complex working conditions and components of the flue gas, the traditional treatment process has problems such as poor adaptability, high energy consumption, long process, and high investment and operation costs when dealing with this type of flue gas. Therefore, the development of adaptable and economically feasible integrated technology for ultra-low emission of industrial flue gas has become the main development direction of...
