High-efficiency coking waste gas treatment device

Abstract

The invention relates to the field of waste gas treatment, in particular to a high-efficiency coking waste gas treatment device which comprises a filtering device, an electrostatic dust collection device, a gas purification device and a purified gas discharge channel. The filtering device comprises a rectangular box body, a filtering plate, a slag scraping mechanism and a slag discharging box, waste gas is introduced through a gas inlet of the rectangular box body and filtered through the filtering plate, and waste slag left on the filtering plate after filtering is scraped by the slag scraping mechanism and falls into the slag discharging box; the electrostatic dust collection device comprises an air entraining funnel and two electrostatic generation mechanisms, the two sides of the air entraining funnel are each provided with a rectangular opening, and the electrostatic generation mechanisms are symmetrically arranged at the rectangular openings; the gas purifying device comprises a reaction tank and a water storage box; the reaction tank comprises a cylindrical tank body, a ventilation tank body, an atomizing nozzle at one end of the cylindrical tank body and a shielding mechanism; and an active carbon plate is arranged in the purified gas discharge channel. The problem that existing waste gas treatment equipment cannot completely and effectively purify waste gas is solved, it is guaranteed that the waste gas is completely purified, and equipment damage caused by excessive waste residues is prevented.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a high-efficiency coking waste gas treatment device. Background technique [0002] Atmospheric pollutants have a greater impact on the weather and climate, thereby destroying the ecological balance, deteriorating the human living environment, causing many serious human diseases, and seriously endangering human health. According to the World Health Organization, air pollution caused about 7 million people in 2012 die. [0003] The existing waste gas treatment equipment purifies the waste gas from bottom to top through layer-by-layer cleaning mechanisms and then discharges it. There is still incompletely purified waste gas in the purified gas; on the one hand, the existing waste gas treatment equipment is not fully Purify the exhaust gas, so that the discharged exhaust gas still contains harmful gases; on the other hand, the long-term operation of the exhaust gas treatment equip...
