Abstract

The invention discloses a steam soot blower for removing and cleaning denitration catalysts, belonging to the field of cleaning equipment for out-of-stock catalysts. It is characterized in that it includes a high-pressure spray gun connected to a steam chamber through a high-pressure gas-liquid pipe and a high-pressure gas-liquid pump. The steam chamber includes a water storage device and a steam generator, and a water inlet purifier is arranged in the water storage device. The invention can thoroughly clean the out-of-stock catalyst in the mid-use period, and avoid the long-term use of the out-of-stock catalyst due to dust accumulation, resulting in failure to reactivate the activity. The invention can completely reduce the purification ability of the catalyst through the cleaning, reduction and purification process, and improve the service quality and service life of the equipment.

Description

technical field [0001] The invention belongs to the field of cleaning equipment for out-of-stock catalysts, in particular to a steam soot blower for SCR de-cleaning and 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 steam soot blower for cleaning and 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 ope...
