Abstract

The invention discloses an in-operation denitration catalyst sampling device and a testing method, which belong to the technical field of SCR denitration, and are used for sampling an in-operation denitration catalyst sample for performance detection. The device comprises a first-layer sampling bin, a second-layer sampling bin, a third-layer sampling bin and a fourth-layer sampling bin, wherein the first-layer sampling bin and the first-layer denitration catalyst are arranged in parallel, the second-layer sampling bin and the second-layer denitration catalyst are arranged in parallel, the third-layer sampling bin and the third-layer denitration catalyst are arranged in parallel, and the fourth-layer sampling bin and the fourth-layer denitration catalyst are arranged in parallel. A denitration catalyst sample taken by the device has good representativeness, the catalyst can be directly taken out for detection without waiting for shutdown of a unit during sampling, the device is reliable, sampling is convenient and fast, and the denitration catalyst in operation can be timely and quickly detected.

Description

technical field [0001] The invention relates to the technical field of SCR denitration, in particular to a sampling device and a testing method for a denitration catalyst in operation. Background technique [0002] The denitrification catalyst plays a vital role in the removal of pollutants in fossil energy utilization equipment, and the good performance of the catalyst is the prerequisite for ensuring the efficient and safe operation of the unit. After the catalyst has been put into operation for a period of time, its performance needs to be tested to ensure that it still has good catalytic performance. At present, the experimental detection of the performance of the denitration catalyst is an important means to check whether the denitration catalyst is operating normally. However, when sampling samples of denitrification catalysts to be tested in operation, because it is necessary to wait for the unit to shut down, it is often impossible to sample and test in time.
