Every time powder adsorption particles pass through one step-by-step replacement dynamic adsorption layer from bottom to top, the organic waste gas in the corresponding step-by-step replacement dynamic adsorption layer is adsorbed and purified, so that the higher the purity of the powder adsorption particles of each step-by-step replacement dynamic adsorption layer from top to bottom, the stronger the adsorption capacity. Pure powder adsorption particles with the maximum adsorption capacity are put in the bottom layer stage-by-stage replacement dynamic adsorption layer 50 closest to the exhaust fan 60, so that the organic waste gas discharged from the exhaust fan 60 out of the adsorption tower 10 is strictly regulated by the pure powder adsorption particles.

The first guide cylinder 24 is used for guiding powder adsorption particles output by the gas-solid mixer 21 on the same layer to uniformly fall on the filter screen plate 22 on the same layer. Illustratively, the first guide cylinder 24 of the top stage-by-stage replacement dynamic adsorption layer 20 is connected to the mixing output end 214 of the gas-solid mixer 21 of the top stage-by-stage replacement dynamic adsorption layer 20, and the first guide cylinder 24 of the top stage-by-stage replacement dynamic adsorption layer 20 faces the filter screen plate 22 of the top stage-by-stage replacement dynamic adsorption layer 20.

When the concentration of the third organic component is greater than the third preset concentration, it indicates that the adsorption capacity of the bottom layer stepwise replacing dynamic adsorption layer 50 is weaker, that is, the adsorption capacity of the powder adsorption particles in the whole adsorption tower 10 is insufficient to completely adsorb and purify the organic component in the organic waste gas, the third jet fan 52 can be controlled to continuously operate and the opening of the third valve 54 is increased, so as to increase the input amount of the powder adsorption particles in the adsorption tower 10, enhance the adsorption capacity of the purification device, ensure the purification effect on the organic waste gas, and strictly control the purity of the gas discharged out of the adsorption tower 10.

In summary, according to the multi-stage mixing filtration type organic waste gas adsorption purification device provided by the utility model, organic waste gas is sent to the gas-solid mixer 21 of the top stage-by-stage replacement dynamic adsorption layer 20, under the action of the exhaust fan 60, the organic waste gas enters the corresponding stage-by-stage replacement dynamic adsorption layer from top to bottom through the gas-solid mixer 21 of each stage-by-stage replacement dynamic adsorption layer, and finally is discharged from the exhaust port 51 to the adsorption tower 10.

The higher the purity of the powder adsorption particles of the dynamic adsorption layer is replaced step by step from top to bottom, the stronger the adsorption capacity is. The lower the concentration of the organic components of the organic waste gas of the dynamic adsorption layer is, the easier the organic components are adsorbed and purified by the powder adsorption particles. After the organic waste gas with the lowest concentration of organic components enters the bottom layer to replace the dynamic adsorption layer 50 step by step, the concentration of the organic components of the organic waste gas is far lower than the emission standard after the organic waste gas is adsorbed and purified by the powder adsorption particles with the strongest adsorption capacity, so that the purifying effect of the organic waste gas is improved.
