Abstract

The invention relates to an integrated treatment device for removing PM2.5 and heavy metal particulate matter in exhaust gas. The integrated treatment device comprises a primary purifying device and a secondary purifying device. The primary purifying device comprises a purifying tank with the upper end opened, and a spraying device is arranged in the purifying tank. A wet-type electric dust remover is arranged in a dust removal cavity, and a first gas outlet is formed in the upper end of the dust removal cavity. The secondary purifying device comprises a purifying barrel with the upper end opened and a drainage gas hood with the upper end opened. The purifying barrel is filled with second absorption liquid, an inlet of the drainage gas hood is communicated with a first outlet pipeline, and the opening of the drainage gas hood is formed in the purifying barrel and located in the second absorption liquid. Based on wet-type dust removal, two stages of disposers are adopted in the device, the PM2.5 contained in the exhaust gas can be well removed while the heavy metal particulate matter of the exhaust gas is treated, and the technical support is provided for establishing the atmospheric emission standards of exhaust gas emission enterprises of the same kind.

Description

technical field [0001] The invention relates to an integrated treatment device for removing PM2.5 and heavy metal particles in waste gas. Background technique [0002] In response to the increasingly serious pollution situation, more and more researchers are devoted to the research on the removal technology of fine particulate matter PM2.5 and heavy metal particulate matter. At present, the internationally recognized technologies mainly focus on the following three methods: improved bag dust removal, wet dust removal, and electric bag composite dust removal. The improved bag dust removal technology has a high removal efficiency for particles with a diameter greater than 2 μm. The technology has strong stability and a wide range of applications, but it has high requirements for flue gas temperature and humidity, serious pressure loss, and large energy consumption. restricted in. Electric bag composite dust removal technology is a new type of dust removal process, which comb...
