Problems solved by technology

[0005] 1. SCR denitrification catalysts can be divided into two types: high-temperature catalysts (300-400°C) and medium-low temperature catalysts (180-300°C): high-temperature catalysts have been widely used in the power industry, and the technology is very mature; A few industries such as coking and glass still have certain technical risks. The main risk is the dust resistance and sulfur resistance of the catalyst. At the same time, the traditional SCR denitration catalyst generally adopts the honeycomb body model, modular assembly, and the denitrification device occupies a large area. One-time investment High, in addition, the space velocity is low, the amount of catalyst is...

Abstract

The invention discloses a combined type radial dust removal and denitration reactor. The combined type radial dust removal and denitration reactor comprises a reactor body, and is characterized in that a plurality groups of chambers for dust removal and denitration of flue gas are mounted in the reactor body; and each chamber is provided with a gas inlet and a gas outlet, the interior of each chamber is divided into an upper chamber and a lower chamber by a division plate and a horizontal pattern plate, the gas inlet is communicated with the lower chamber, the gas outlet is communicated with the upper chamber, a plurality of dust collecting cloth bags are arranged in the lower chamber, bag openings of the plurality of dust collecting cloth bags are buckled on the pattern plate, a soot blowing pipeline is mounted above the pattern plate, a radial denitration bed layer corresponding to the dust collecting cloth bags isalso arranged in the chamber, and the flue gas penetrates through the dust collecting cloth bags and the radial denitration bed layer sequentially in a radial flowing mode. The combined type radial dust removal and denitration reactor provided by the invention is simple and novel in structure, integrates a denitration device and a dust removal device, does not need to add a flue gas uniform distribution device, and reduces investment and equipment floor area while ensuring the denitration efficiency.

Description

technical field [0001] The invention relates to an industrial flue gas purification treatment device, in particular to a combined radial dust removal and denitration reactor. Background technique [0002] my country is a big coal-burning country. Coal burning, coking, glass and other production processes will generate a certain amount of dust, SO 2 , nitrogen oxides and harmful metal elements, etc., NO in flue gas X Emission ratio of SO 2 The harm to the environment is more serious. The emission of a large amount of nitrogen oxides will cause a series of environmental problems such as acid rain, photochemical smog, ozone layer destruction and greenhouse effect, especially the serious "haze" phenomenon that has occurred in most parts of the country in recent years. The root cause is the emission of nitrogen oxides. Controlling the emission of nitrogen oxides in the atmosphere has attracted global attention, and it is also the focus and difficulty of protection in the current...
