Abstract

The invention discloses a flow-adjustable denitration catalyst wear strength testing device and a testing method, which are used for detecting the wear strength of a denitration catalyst testing platform. The testing device comprises a comparison bin, a testing bin, a feeder, a dust remover, an induced draft fan, a flow meter, a first branch pipe, a first adjusting valve, a first flow meter, a second branch pipe, a second adjusting valve and a second flow meter. The comparison bin, the testing bin, the dust remover and the induced draft fan are sequentially connected, the first branch pipe is connected with the comparison bin in parallel, the second branch pipe is connected with the testing bin in parallel, the first adjusting valve and the first flow meter are installed on the first branch pipe, the second adjusting valve and the second flow meter are installed on the second branch pipe, and the flow meter is connected to an inlet pipeline of the comparison bin. And a feeder is connected to the pipeline between the comparison bin and the test bin. The device can simulate the wear condition in the actual catalyst operation, controls the flow passing through the comparison sample and the test sample to be consistent and to be a predetermined value specified in the test standard, and is high in test result reliability.

Description

technical field [0001] The invention relates to a flow-adjustable denitrification catalyst abrasion strength test device and a test method, which belong to the field of industrial waste gas treatment and monitoring. Background technique [0002] Selective Catalytic Reduction SCR (Selective Catalytic Reduction) denitrification technology is the main technology for removing harmful nitrogen oxides in the exhaust gas of coal-fired units at home and abroad. The wear resistance of the catalyst is the premise guarantee for the high-efficiency denitrification of the catalyst, and plays a vital role in the safe operation of the unit. [0003] At present, the main principle of the anti-wear test device for denitrification catalysts is to measure the relative wear rate through the mass loss of the comparison sample and the test sample. Although these devices considered the mass loss of the catalyst caused by the dusty air as the carrier during the test, they did not control the amoun...
