Description

Technical Field

[0001] The utility model relates to the field of fluidized bed design, in particular to a horizontal fluidized bed dust removal system. Background Art

[0002] Horizontal fluidized beds are suitable for drying, cooling, and humidifying granular materials such as feed additives, grains and oils, slag, salt, and sugar. They have the advantages of high heat transfer efficiency and easy maintenance of the bed temperature.

[0003] Horizontal fluidized beds are usually equipped with an exhaust system to facilitate the discharge of excess exhaust gas from the bed during operation. However, since horizontal fluidized beds are primarily used to process granular materials, they produce a large amount of dust from the granular materials during processing. This dust is inevitably present in the exhaust airflow, which can easily clog the exhaust system. Furthermore, the dust passing through the exhaust system causes material loss, reduces material utilization, and pollutes the environment. Utility Model Content

The other end of the first air pipe 5 is fixedly connected to the side of the cyclone separator 2 via bolts, and this end of the first air pipe 5 is connected to the cyclone separator 2. This connects the horizontal fluidized bed body 1 and the cyclone separator 2, and connects the cavity and the cyclone separator 2.

[0023] The horizontal fluidized bed dust removal system of the present invention also includes a second air pipe 6. An air outlet is provided at the top of the cyclone separator 2. One end of the second air pipe 6 is fixedly connected to the air outlet at the top of the cyclone separator 2 via a flange. This connected end of the second air pipe 6 communicates with the cyclone separator 2. The other end of the second air pipe 6 is fixedly connected to the bag-type dust collector 3 via bolts. This connected end of the second air pipe 6 also communicates with the bag-type dust collector 3. This connects and communicates the cyclone separator 2 and the bag-type dust collector 3.

[0024] The bag dust collector cabinet 3 is provided with a long strip of cloth bag, which can be used for filtering dust.

[0025] The horizontal fluidized bed dust removal system of the present invention also includes a third air pipe 7. The fan 4 is provided with an air intake 41 and an air outlet 42.

This connects the fan 4 to the bag-type dust collector 3, and the air intake 41 is in communication with the bag-type dust collector 3.

[0026] When the present invention is in use, the exhaust gas discharged from the cavity of the horizontal fluidized bed body 1 can enter the cyclone separator 2 through the first air pipe 5, and the cyclone separator 2 can perform gas-solid separation on the exhaust gas, so that most of the dust contained in the exhaust gas can be separated by the cyclone separator 2, and the separated dust can be collected by the cyclone separator 2 and output to the external raw material recovery equipment, and the gas processed by the cyclone separator 2 can be input into the bag dust collector 3 through the second air pipe 6, and the bag dust collector 3 can filter and collect the remaining dust in the gas entering it again to further reduce the amount of dust contained in the gas.

[0027] Finally, the gas treated by the bag dust collector 3 can enter the exhaust port 41 of the fan 4 through the third air pipe 7. When the fan 4 is working, the gas after multiple dust removal treatments can be discharged from the exhaust port 42 of the fan 4, and the exhaust port of the fan 4 can be directly connected to the atmosphere, or connected to an external processing equipment to further process the exhaust gas.

[0030] When the horizontal fluidized bed body 1 requires the incoming gas to have a certain temperature, the fresh air heating system 8 can heat the gas input into the horizontal fluidized bed body 1. Specifically, the fan 4 can extract air from the outside and transport it to the filter 82. The filter 82 can filter the incoming gas to reduce the impurities it contains. The gas can then flow into the heating device 83, where it is heated to a specific temperature, and finally flows into the horizontal fluidized bed body 1 through the connecting pipe 9.
