Chemical waste gas integrated treatment device

Abstract

The invention discloses a chemical waste gas integrated treatment device, comprising a desulfurization and denitrification dedusting box; the bottom of the desulfurization and denitrification dedusting box is connected with a setting tank through a communicating pipe, a demister is arranged on the upper side of the interior of the desulfurization and denitrification dedusting box, and a liquid distribution device is arranged on the lower side of the demister and is provided with a liquid inlet tube; the liquid inlet tube is provided with a booster pump, and the other end of the liquid inlet tube is connected with a desulfurization aqueous solution tank; a plurality of atomizers are installed on the lower side of the liquid distribution device, and a silk screen is arranged on the lower side of the liquid distribution device; a variable frequency motor is installed on the middle part of a motor rack at the lower side of the silk screen, a baffle plate is installed on the upper side output shaft of the variable frequency motor, a flue gas inlet pipe is also arranged on the lower part of the left side of the desulfurization and denitrification dedusting box and is provided with a wetelectrostatic precipitator. The chemical waste gas integrated treatment device is simple in structure, low in manufacture and running cost, good in flue gas desulfurization and denitrification effect,high in efficiency and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to an integrated treatment device for chemical waste gas. Background technique [0002] Flue gas desulfurization and denitrification technology is a boiler 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. The benefits of ambient air purification are numerous. Currently 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. The existing flue gas desulfurization and denitrification devices have poor stability, low desulfurization and denitrification efficiency, poor effect, and cannot perform pre-dust removal, resulting in a ...

AI Technical Summary

Problems solved by technology

The existing flue gas desulfurization and denitrification devices have poor stability, low desulfurization and denitrification efficiency, poor effect, and cannot perform pre-dust removal, resulting in a large workload of the device. In addition, the composition of the flue gas is complex, and after spraying, it will still carry a large amount of mist Drops and particles
