Automatic reversing and cleaning device of spherical catalyst for coke oven flue gas desulfurization

Abstract

The invention discloses an automatic reversing and cleaning device of a spherical catalyst for coke oven flue gas desulfurization. The device comprises a base and an annular rotating plate rotationally connected to the top of the base, wherein a driving mechanism used for driving the rotating plate to rotate is arranged at the top of the base, a fixing mechanism used for fixing the spherical catalyst is arranged above the rotating plate, a cleaning mechanism and a reversing mechanism are arranged on one side of the base, the cleaning mechanism sprays water to clean the catalyst, the reversing mechanism reverses the cleaned spherical catalyst, and the fixing mechanism comprises a plurality of first fixing seats fixed to the top of the rotating plate and evenly distributed, rotating discs rotationally connected to the tops of the first fixing seats, containing seats rotationally connected to the tops of the rotating discs, a mounting frame fixed to one side of the base, and a first air cylinder mounted on the mounting frame and vertically arranged. The cleaning device is capable of automatically reversing the catalyst, free of cleaning dead angles, good in cleaning effect, high in automation degree and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of cleaning spherical catalysts, in particular to an automatic reversing cleaning device for spherical catalysts used in coke oven flue gas desulfurization. Background technique [0002] Among the denitrification technologies of many coal-fired power plants, SCR (Selective Catalytic Reduction) is the most widely used and most mature and effective flue gas denitrification technology in the world. Catalyst is the core of SCR technology, accounting for about 40% of the total cost of the whole denitrification device. After the SCR catalyst has been used for a period of time, there will be more or less fouling or even blockage of the catalyst pores and catalyst poisoning, which will lead to a decrease in denitrification efficiency and may cause malfunctions in unit operation. Therefore, it is very necessary to clean and regenerate the catalyst with fouling and activity decline, which can greatly save the cost of...
