A flue gas purification equipment and purification method for desulfurization and denitrification of industrial naphthalene waste gas

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...

AI Technical Summary

Problems solved by technology

[0004] For the desulfurization and denitrification treatment of industrial naphthalene waste gas, the existing desulfurization and denitrification towers are difficult to meet the increasing flue gas emissions, and the device needs to be maintained and repaired, filter replacement, etc. after long-term use, but such operations will cause The equipment cannot be used for a short period of time, which affects the treatment efficiency; therefore, in order to improve the efficiency of desulfurization and denitrification of waste gas, optimize the existing treatment equipment to solve the above-mentioned problems and promote the development of waste gas treatment
