Abstract

The invention discloses a hole dredging tool for a denitration catalyst. The tool comprises hole dredging pipes, an air cavity plate, hydraulic push rods connected with a hydraulic motor and a hydraulic oil tank, a hose connected with an air pump provided with an electromagnetic valve, and pistons. The plurality of hole dredging pipes are uniformly arranged on one side of the air cavity plate in amatrix manner, and the hole dredging pipes are communicated with an air cavity of the air cavity plate. The periphery of the other side of the air cavity plate is connected with the hydraulic push rods connected with the hydraulic motor and the hydraulic oil tank. The side face of the air cavity plate is connected with the hose connected with the air pump provided with the electromagnetic valve.The pistons are arranged in an inner cavity of the air cavity plate, and the four side faces of the pistons are in corresponding contact with the side wall of the air cavity plate. The hydraulic pushrods connected with the hydraulic motor and the hydraulic oil tank are in transmission connection with the pistons. According to the invention, compressed air and hydraulic propelling force are alternately used, so that the coal ash in micropores is effectively dredged and cleaned, and the hole dredging operation of all honeycomb type denitration catalysts can be met.

Description

technical field [0001] The invention relates to the field of through-hole cleaning equipment for denitration catalysts, in particular to a through-hole tool for denitration catalysts. Background technique [0002] The size of the windward side of the existing honeycomb denitrification catalyst unit body is fixed at 150mm*150mm (GB / T31587-2015) as the design basis, and the overall design realizes this through-hole tool. 25 holes) to prepare through-hole parts corresponding to the number of through-hole tubes, but it cannot meet the through-hole operation for all honeycomb denitration catalysts, and cannot solve the problem of ash accumulation, sintered fly ash, and hardened pulverized coal in square honeycomb micropores with a pore diameter less than 5mm Ash cleaning, aiming at these defects, so it is necessary for us to design a through-hole tool for denitrification catalyst. Contents of the invention [0003] The purpose of the present invention is to provide a through-h...
