Problems solved by technology
[0004] The three-stage intermittent operation sealing method cannot realize the continuous flow of materials, and the amount of sealing gas is large
However, this method is only applicable to the condition that the sealing gas in the material storage bin is under positive pressure and the pressure is not high. At the same time, the actual height of the material storage bin will be greatly increased, resulting in an increase in construction costs.

Embodiment Construction
[0019] The relative closing device of the granular material storage bin of the present invention is more suitable for the material storage bin as a process system requiring sealing process equipment, especially in the continuous movement of the material storage bin as process equipment. Taking the typical activated carbon and activated coke desorption activation regeneration reaction device as an example, the nature of activated carbon and activated coke determines that the desorption reaction device of activated carbon and activated coke must be a large storage warehouse structure that strictly isolates the air and ensures sufficient residence time. The desorption process of activated carbon and activated coke will inevitably release a large number of pollutants, and the activation regeneration process has CO, H 2 Toxic, harmful and dangerous gases are generated, activated carbon and activated coke desorption activation regeneration reaction device must be strictly sealed to p...

The invention relates to a relative closing device for granular material storage bins, which is sequentially provided with a feed bin 1, a first material communicating tube 2, a material storage bin 3, a second material communicating tube 5 and a discharge bin 4 from top to bottom, wherein the two ends of the first material communicating tube are respectively connected with the feed bin and the material storage bin, and the two ends of the second material communicating tube are respectively connected with the material storage bin and the discharge bin. According to the invention, the inner part of a granular material storage bin is relatively closed, the sealing property of an air-phase environment is good, and only a small amount of seal gas is discharged, so that materials can realize a normal continuous motion, and external environment air can not enter the granular material storage bin.
Description
technical field [0001] The invention relates to a relative closing device for a granular material storage bin, more specifically, relates to a relative sealing device for a granular material storage bin and an adjacent bin body to ensure that the environment in the material storage bin is relatively sealed when the material is stationary or moving. device of. Background technique [0002] Due to the special properties of the stored materials, some granular material storage bins need to be sealed to isolate them from contact with the air, or to isolate them from other adjacent bins. For example, the storage of some granular catalysts needs to be isolated from the air to prevent them from losing their catalytic activity due to water absorption or oxidation in contact with air. This is especially true for some granular materials that are easily combusted or even exploded in contact with air at high temperatures. The typical example is the heating and desorption process of acti...
