Device and method for catalyst-regenerable high-temperature catalytic pyrolysis of domestic garbage and hydrogen filtering

Abstract

The invention discloses a device and method for catalyst-regenerable high-temperature catalytic pyrolysis of domestic garbage and hydrogen filtering. The device includes a fluidized bed pyrolysis furnace, microwave generators, a catalyst regenerable catalyst bed, a combustion furnace and a cyclone separator. The bottom of the fluidized bed pyrolysis furnace is provided with a gas inlet. The microwave generators are arranged on the side wall of the fluidized bed pyrolysis furnace and the bottom or the side wall of the catalyst regenerable catalyst bed. An inlet of the cyclone separator is connected to a pyrolysis gas outlet of the fluidized bed pyrolysis furnace, the bottom of the cyclone separator is connected to the lower part of the fluidized bed pyrolysis furnace, and a gas outlet of the cyclone separator is connected to the catalyst bed. A gas outlet of the catalyst bed is connected to the combustion furnace. Through the device and the method, microwave-assisted high-temperature pyrolysis of domestic garbage, catalyst regeneration and hydrogen filtration can be achieved, the catalytic pyrolysis efficiency can be increased, external energy supply cab be reduced, energy is savedwhile achieving resource utilization of domestic garbage, the service lifetime of the device can be effectively prolonged, and the device and the method are economical and environmentally friendly.

Description

technical field [0001] The invention relates to a system for producing gas fuel by high-temperature pyrolysis domestic garbage with continuous production process, in particular to a high-temperature catalytic pyrolysis domestic garbage hydrogen filter device and method with regenerable catalyst. Background technique [0002] Nowadays, with the rapid economic and social development, the urbanization process is accelerating, and the garbage generated in urban production and life is also increasing rapidly. The study found that urban waste has the characteristics of coexistence of resources and hazards. On the one hand, the large increase of urban domestic waste has seriously affected the ecological environment, leading to a very serious problem of waste disposal land; on the other hand, domestic waste contains a large amount of biomass energy, and biomass is clean and renewable due to its advantages Become the best raw material for the preparation of renewable clean energy.
