Embodiment 1

[0063] The flue gas purification method of industrial naphthalene waste gas desulfurization and denitrification based on the above-mentioned flue gas purification device comprises the following steps:

[0064] S1: Spread the acrylic fiber to the filler drawer 52, and evenly cover the acrylic fiber with activated carbon, porous ceramics, and iron oxide mixed powder, repeat the above-mentioned laying of 6 layers of desulfurization filler composed of acrylic fiber + mixed powder; Filler balls with a particle size of 1-2 mm obtained by mixing and granulation constitute denitrification fillers and fill them into the filler drawer 52, fill the ammonia water into the reaction solution chamber 14, and fill the desiccant into the exhaust chamber 15;

[0065] S2: Pass the industrial naphthalene waste gas into the dust removal ring bin 16 of the flue gas purification equipment, perform preliminary dust removal treatment on the industrial naphthalene waste gas through the dust removal filt...

Embodiment 2

[0071] This embodiment is basically the same as Embodiment 1, except that the combination of denitrification and desulfurization fillers is different, specifically:

[0072] The denitration filler includes, in parts by mass: 8 parts of magnesium chloride, 1 part of heteropolyacid, 1 part of glass fiber, 3 parts of expanded vermiculite powder, and 0.5 part of binder. The desulfurization filler includes, in parts by mass: 10 parts of activated carbon, 3 parts of porous ceramics, 8 parts of iron oxide, and 10 parts of acrylic fiber.

Embodiment 3

[0074] This embodiment is basically the same as Embodiment 1, except that the combination of denitrification and desulfurization fillers is different, specifically:

[0075] The denitration filler includes, in parts by mass: 15 parts of magnesium chloride, 2 parts of heteropoly acid, 2 parts of glass fiber, 7 parts of expanded vermiculite powder, and 1.5 parts of binder. The desulfurization filler includes, in parts by mass: 15 parts of activated carbon, 5 parts of porous ceramics, 10 parts of iron oxide, and 20 parts of acrylic fiber.

Abstract

The invention discloses a flue gas purification equipment and purification method for industrial naphthalene waste gas desulfurization and denitrification, comprising: a combined tower body surrounded by multiple groups of branch towers, and multiple groups of water distribution rotations are arranged at equal intervals in the middle and lower parts of the branch towers device; the upper part of the support tower is equipped with a packing assembly; the reaction liquid warehouse is located at the bottom of the center of the combined tower body, and the reaction liquid warehouse is connected to each spray plate through the delivery liquid pump and hose; the top center of the reaction liquid warehouse is provided with a drive The motor, the connecting rod driving the output shaft of the motor is connected to the corresponding water distribution rotating device through each drive assembly; the exhaust chamber located on the top of the combined tower body is connected to the top of each support tower; the ring structure of the dust removal ring warehouse is sleeved on the combined tower The outer periphery of the lower end of the body communicates with the air inlets of each branch tower. The invention can carry out regular inspection and maintenance on the combined tower body or alternately replace the fillers in each branch tower, so that the combined tower body can maintain a stable desulfurization and denitrification effect under continuous operation.

Description

technical field [0001] The invention relates to the technical field of industrial waste gas treatment, in particular to a flue gas purification device and a purification method for desulfurization and denitrification of industrial naphthalene waste gas. Background technique [0002] Flue gas desulfurization and denitrification technology is a flue gas purification technology applied to the chemical industry where nitrogen oxides and sulfur oxides are generated. Nitrogen oxides and sulfur oxides are one of the main sources of air pollution; therefore, the application of this technology is harmful to the environment. There are many benefits of air purification; known flue gas desulfurization and denitrification technologies include PAFP, ACFP, pyrolusite method, electron beam ammonia method, pulse corona method, gypsum wet method, catalytic oxidation method, microbial degradation method and other technologies. [0003] There are three main types of simultaneous flue gas desulf...
