Apparatus and method for detecting wear resistance of flue gas denitration catalyst

Abstract

The invention relates to an apparatus and method for detecting the wear resistance of a flue gas denitration catalyst. No apparatus or method for detecting the wear resistance of the catalyst exists at present, so the mechanical strength of the catalyst is difficult to control. The apparatus comprises a test sample bin and an apparatus rack, and also comprises a quartz sand feeder, a wind blower, a wind speed measurer, a wind speed adjusting device, a contrast sample bin, a feeding homogenizer, a discharging tube, a wind tube, a differential pressure measuring device, a cloth bag deduster and an abrasive collection barrel, one end of the wind tube is connected with the wind blower, the other end of the wind tube is connected with the abrasive collection barrel, the wind speed adjusting device, the wind speed measurer, the feeding homogenizer, the test sample bin and the differential pressure measuring device are mounted on the wind tube, and the contrast sample bin is connected with the test sample bin serially or in parallel. The disadvantages of high performance detection cost and unable complete simulation of onsite practical running conditions of present SCR denitration catalysts are overcome in the invention.

Description

technical field [0001] The invention relates to a device and method for detecting wear resistance of a flue gas denitrification catalyst, belonging to the technical field of environmental protection. Background technique [0002] During the "Twelfth Five-Year Plan" period, the domestic large-scale denitrification transformation has resulted in the diversification of the SCR denitration catalyst market, the uneven quality of the catalyst, and the existence of various quality problems in the catalyst. The flue gas denitrification devices of coal-fired units all adopt the high-ash layout method. Due to the characteristics of coal types in my country and the reasons for controlling coal-burning costs in thermal power plants, power plants often use high-calcium-magnesium and low-quality coal, etc., and use these types of coal The soot particles generated are large, high in hardness, and complex in composition. Therefore, the SCR catalyst needs to be washed and worn by the air flow...
