Apparatus for cleaning denitration catalyst in middle period of application

Abstract

The invention discloses a mid-use cleaning device for a denitrification catalyst, which belongs to the field of cleaning equipment for out-of-stock catalysts. It is characterized in that it includes a frame, a main blower, a side blower, an external blowing pipe, and an internal blowing pipe; the main blower and the side blowing pipe are installed on the frame, and the main blower is connected to the external blowing pipe and the internal blowing pipe; the external blowing pipe is connected to the external blowing nozzle, The inner blowpipe is connected with the inner mouthpiece. It can thoroughly clean the out-of-stock catalyst in the middle of use, and avoid the long-term dust accumulation of the out-of-stock catalyst, which makes it impossible to activate the activity again. In addition, the present invention can completely reduce the purification ability of the catalyst through the integrated equipment operation of blowing, cleaning and reduction, and improve the service quality and life of the equipment.

Description

technical field [0001] The invention belongs to the field of cleaning equipment for out-of-stock catalysts, and in particular relates to a mid-use cleaning device for SCR denitrification catalysts. Background technique [0002] After the out-of-stock catalyst is used for a period of time, due to the high-dust working environment and the poisoning of exhaust gas, the out-of-stock catalyst will become blocked, poisoned and other failures. A depleted catalyst can only be rejuvenated by thorough cleaning and reduction. [0003] In order to solve the above technical problems, the applicant has developed a mid-use cleaning device for denitrification catalysts, which thoroughly cleans out-of-stock catalysts in the middle of use, and avoids long-term dust accumulation of out-of-stock catalysts, resulting in inability to reactivate the activity. In addition, the present invention can completely reduce the purification ability of the catalyst through the integrated equipment operatio...
