Problems solved by technology
The desulfurization and denitrification system is the most important part of it. During the use of denitrification catalysts, they are made into modules one by one called desulfurization and denitrification system modules, and then multiple desulfurization and denitrification system modules are installed. The existing desulfurization and denitrification system modules System modules are usually installed on frame-shaped sheet metal parts, but the existing desulfurization and denitrification system modules lack an effective calibration and positioning structure during installation, resulting in inaccurate positioning of desulfurization and denitrification system modules during fixed installation, affecting normal use

The invention provides a special high-precision sheet metal part for a desulfurization and denitrification system and belongs to the technical field of flue gas treatment, aiming at solving the problem that the positioning precision of an existing sheet metal part is poor. According to the special high-precision sheet metal part for the desulfurization and denitrification system, the sheet metal part comprises a plate part I and a plate part II which are vertical to each other; the plate part I and the plate part II are rectangular; a plurality of inward convex positioning parts are arranged on the inner side face of the plate part I; punching holes, formed by punching through a plurality of punching machines, are formed in the outer side face of the plate part I; the punching holes correspond to the positioning parts one by one; the punching holes correspond to the positioning parts one by one; the rear side of the plate part I is connected with the top side of the plate part II; a concave positioning groove is formed in the bottom side of the plate part II. According to the sheet metal part, the positioning parts, which protrude toward the inner part of the sheet metal part, are directly punched on the plate part I, and a desulfurization and denitrification system which is arranged in a honeycomb shape is convenient to fix; the special high-precision sheet metal part is more convenient and rapid to fix and mount; meanwhile, the positioning is more accurate.
Description
technical field [0001] The invention belongs to the technical field of flue gas treatment, and relates to a special high-precision sheet metal part for a desulfurization and denitrification system. Background technique [0002] The Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China jointly issued the newly revised "Emission Standards of Air Pollutants for Thermal Power Plants". The new standards will be implemented on January 1, 2012, and the control and treatment of nitrogen oxide pollution is being vigorously implemented. Flue gas denitrification in coal-fired power plants is an important way to control NOx. The desulfurization and denitrification system is the most important part of it. During the use of denitrification catalysts, they are made into modules one by one called desulfurization and denitrification system modules, and then multiple desulfurization and denitrifi...
