Flue gas purification device

Abstract

The invention discloses a flue gas purification device, comprising a purifying barrel, a support frame and a mounting rack installed on the support frame in a detachable way, wherein the upper end and the lower end of the purifying barrel are in circular arc shapes, a flue gas outlet is formed in the top of the purifying barrel, and a spray water outlet is formed in the bottom of the purifying barrel; a spray water inlet is formed in the barrel wall at the upper part of the purifying barrel, and a flue gas inlet is formed in the barrel wall at the lower part of the purifying barrel; the purifying barrel is internally provided with a spray device communicated with the spray water inlet; the mounting rack comprises a circular barrel arranged at the upper part, and an arc-shaped barrel, matched with the bottom of the purifying barrel, arranged at the lower part; the inner diameter of the arc-shaped barrel is equal to the outer diameter of the bottom of the purifying barrel; the support frame comprises a ring-shaped mounting seat and a plurality of support rods arranged at the bottom of the mounting seat; the inner surface of the mounting seat is matched with the outer surface of the arc-shaped barrel. The flue gas purification device has the beneficial effects that the existing point contact manner between the purifying barrel and a bracket is changed into a surface contact manner, so that the contact area between the purifying barrel and the bracket is enlarged, and the technical defect that the purifying barrel is damaged due to larger local stress is overcome.

Description

technical field [0001] The invention relates to a flue gas purification device, which belongs to the technical field of gas purification. Background technique [0002] Air pollution is one of the most concerned issues at present. The main source of air pollution is the emission of flue gas. The flue gas contains incompletely combusted particulate matter, nitrogen oxides and sulfur oxides. The main manifestations of particulate matter are PM2.5, etc., nitrogen oxides and sulfur oxides are the main pollutants that form acid rain. In order to solve the problem of environmental pollution, flue gas purifiers are often used to treat flue gas. [0003] At present, most of the flue gas purifiers for burners such as boilers are composed of purifiers, flue gas inlets, flue gas outlet spray devices, etc. Since the purifiers are of a cylindrical structure, the spray water is sprayed from top to bottom and enters the purifier. The boiler flue gas is directly discharged after spraying. T...
