Problems solved by technology
At present, there is no self-developed device to realize the selective catalytic reduction method in China, but relies on imported devices. The imported devices have complex structures, large construction investment, large floor area, long process, large resistance, high operating costs, and at the same time need to pay. The high technical usage fee is restricted by others in terms of construction period and technology, and the temperature requirements for the flue gas are still high, and the temperature of the flue gas is completely dependent on heating, which wastes energy

Embodiment
[0015] As shown in the attached figure, a honeycomb-shaped purifier is built by staggering the combined modules layer by layer. After the flue gas enters the purifier, it is mixed with the atomized reducing agent to reduce the nitrogen oxides in the flue gas and eliminate nitrogen oxides. The concentration of pollutants reaches pollution-free discharge, and the staggered arrangement of masonry enables the modules to bite each other. The adjacent modules and the layers are cemented and sealed by refractory cement, which greatly improves the sealing and firmness.

The invention provides a flue gas purifier combination module. The flue gas purifier combination module comprises a cylinder filler body, the middle of the cylindrical filler body is provided with a central cylinder, four 1 / 2 arc surfaces are arranged on the outer wall of the central cylinder in every direction, a 1 / 4 arc surface is arranged between two adjacent 1 / 2 arc surfaces, each of the 1 / 2 arc surfaces and a 1 / 2 arc surface on an adjacent cylindrical filler body compose a small cylinder, each of the 1 / 4 arc surfaces and 1 / 4 arc surfaces on an adjacent four cylindrical filler bodies compose a large cylinder, bosses are arranged on the 1 / 2 arc surfaces and the 1 / 4 arc surfaces and at the edges of two ends of the central cylinder on the upper and lower end surfaces of the cylindrical filler body, a groove is formed between the bosses, and the diameter of the external circle of each of the bosses at two ends of the central cylinder is same to the diameter of the large cylinder composed of the four 1 / 4 arc surfaces.
Description
technical field [0001] The invention relates to the technical field of environmental protection technology, in particular to a combination module of a flue gas purifier. Background technique [0002] Nitrogen oxides are one of the main harmful substances that pollute the atmosphere. They are extremely harmful to the human body, and can also induce photochemical smog and lead to the formation of acid rain. Industrial furnaces such as boilers in power plants, melting furnaces in glass factories, smelting furnaces in iron and steel plants, and catalyst generating furnaces produce a large amount of harmful substances such as nitrogen oxides (NOx) during production. At present, there are two methods of dry and wet methods for the treatment of nitrogen oxides and NOx waste gas. The wet method has the disadvantages of low equipment investment, low purification efficiency, and secondary pollution of wastewater. The dry method mainly includes selective non-catalytic reduction method...
