Embodiment 1

[0065] Taking pairs of opposing nozzles as an example, the catalyst strength of the FCC catalyst-air system was measured. The measurement process was as follows: 20g of catalyst was placed in the mixture container, and the air flow rate was 0.5m 3 / h, the running time is 5h, during which the container wall is manually tapped to prevent the catalyst from accumulating on the wall. Samples were taken after the experiment, and the particle size distribution before and after wear was measured by a particle size analyzer. It was found that the average particle size of the FCC catalyst dropped from 76.1 μm to 71.3 μm.

Embodiment 2

[0067] Taking pairs of opposing nozzles as an example, the catalyst strength of the FCC catalyst-water system was measured. The measurement process was as follows: 20g of catalyst was placed in the mixture container, and the water flow rate was 0.5m 3 / h, the running time is 5h. Samples were taken after the experiment, and the particle size distribution before and after wear was measured by a particle size analyzer. It was found that the average particle size of the FCC catalyst dropped from 76.1 μm to 68.6 μm.

Embodiment 3

[0069] Taking pairs of opposing nozzles as an example, the catalyst strength of the FT catalyst-air system was measured. The measurement process was as follows: 20g of catalyst was placed in the mixture container, and the air flow rate was 0.5m 3 / h, the running time is 5h, during which the container wall is manually tapped to prevent the catalyst from accumulating on the wall. Samples were taken after the experiment, and the particle size distribution before and after wear was measured by a particle size analyzer. It was found that the average particle size of the FT catalyst dropped from 75.4 μm to 67.2 μm.

Abstract

The invention relates to the field of catalyst strength measurement, and discloses a catalyst strength measuring device, a nozzle and a nozzle assembly.The catalyst strength measuring device comprises a mixture container (1), the nozzle, a conveying pipe (11) and a driving part (3), and the nozzle comprises a main body pipe (12) and a drainage pipe (13); the drainage tube (13) comprises a first section in the main body tube (12) and a second section extending to the outside of the main body tube (12), and the through-flow area of the position where the first section is located is smaller than the through-flow areas of the upstream and the downstream of the first section so that a Venturi nozzle can be formed. According to the technical scheme, the catalyst particles are sucked into the nozzle under the condition that the catalyst particles are not in contact with the power equipment, so that the catalyst particles are endowed with power to form fluid flow with speed, the situation that the catalyst strength measurement result is influenced by abrasion and collision of the power equipment and the catalyst particles is avoided, and the catalyst strength measurement accuracy is improved.

Description

technical field [0001] The invention relates to the field of catalyst strength measurement, in particular to a catalyst strength measurement device, a nozzle, and a nozzle assembly. Background technique [0002] Based on the domestic energy conditions of "rich in coal, poor in oil, and low in gas", vigorously developing coal chemical technology is not only an important direction for clean coal utilization, but also can alleviate the contradiction between supply and demand of liquid fuels, which has important strategic significance. Due to its relatively mild operating conditions, wide application conditions, and relatively mature technology, the indirect coal liquefaction technology is a hot project for investment and construction at home and abroad. At present, the main development trend of chemical equipment at home and abroad is scale and intensification, which poses a severe test to the operating environment of catalysts, especially the strength of catalysts. In additio...
