Embodiment 2

[0061] Dosing to the regenerator of a pilot plant, the dosing port elevation is 12m, the state of the regenerator: normal pressure, normal temperature, 120 kg of dosing is to be added, and the median diameter of the catalyst is 76-78μm. Dosing tanks are located on the ground. The main operation process: ① Weigh 40 kg of catalyst to be added on the weighing scale; ② Close the control ball valve 3, slightly open the main air (open the mainstream air outlet 12 valve), and the pressure gauge reverse blowing (open the reverse blowing outlet 14) each 0.1m 3 / h, the valve opening of the vent pipeline 8 is 1 / 3, and the agent is added to the fluidized storage tank 2 through the funnel; ③Close the valve 8 of the vent pipeline, and open the main air to 1.0m 3 / h, loose wind (realized by opening the loose air port 13) and pressure gauge back blow 0.1m each 3 / h, pressurize the fluidized storage tank 2 until 0.10-0.15MPa; ④ open the control ball valve 3, and keep the loose air at 0.1m 3 ...

Embodiment 3

[0064] After 50 hours of continuous operation of a pilot plant, the particle size of the catalyst in the reactor changed, and the conversion rate of raw materials decreased. In order to maintain the reaction index, 10 kg of regenerator was added to the pilot plant, and the median diameter of the catalyst was 36-38 μm. The elevation of the dosing port of the regenerator is 10m, the status of the regenerator: pressure 0.10MPa, 620°C, 10kg of supplement is required. Dosing tanks are located on the ground. The main operation process: ① Weigh 10 kg of catalyst to be added on the weighing scale; ② Close the control ball valve 3, slightly open the main air 12, and the pressure gauge reverse air 14, each 0.1m 3 / h, vent pipeline (valve) 8 opening degree 1 / 3, add agent to fluidized storage tank 2 through funnel; ③Close vent pipeline valve 8, open main air 12 to 0.5m 3 / h, loose 13 and pressure gauge blowback each 0.1m 3 / h, pressurize the fluidized storage tank 2 until 0.20MPa; ④ ope...

Description

technical field [0001] The invention belongs to the technical field of fluidized bed auxiliary equipment, and relates to a feeding device, in particular to a mobile catalyst feeding device and a feeding method thereof. Background technique [0002] Fluidized bed technology has been widely used in the development of new energy chemical industry, especially in the research and development of new coal chemical technology. Among them, powder catalyst is an important material to participate in the reaction. Various catalyst delivery equipment are widely used in the pilot test site, and the delivery equipment used to supplement catalyst consumption is generally called dosing tank. In the fluidized bed process, the microsphere catalyst flows continuously between the reactor and the regenerator under the high-speed airflow, so as to realize the continuous progress of the reaction and regeneration process. Due to the severe friction and collision between the particles and between th...
