Metal foam carrier catalysis bed solar energy absorption reaction device

Abstract

The invention discloses a metal foam carrier catalysis bed solar energy absorption reaction device. The device comprises a linear solar energy absorption reactor and a parabolic trough-type solar energy condenser. The linear solar energy absorption reactor is arranged in the focal line of the parabolic troughtype solar energy condenser. The linear solar energy absorption reactor has a bushing structure, and comprises an external glass bushing, an internal metal tube, a selective coating on the surface of the metal tube through vacuum evaporation and a catalyst bed layer with metal foam materials as carriers and arranged inside the metal tube. The device makes the best of the space in the reactor. The catalyst bed layer structure can maintain uniformity and stabilization for long time, has a long service life, and has high efficiency of conversion from solar energy to thermal energy. The catalyst bed layer has a high specific surface area and good catalytic performance. The operations of change and regeneration of catalysts are simple. The device solves the problems of low specific surface area, uneven filling of internal catalysts, difficulty control of temperature field and flow field, difficulty maintenance and the like of reactor catalysts in the prior art.

Description

Technical field [0001] The invention relates to the technical field of solar heat collection and thermal power generation, in particular to a parabolic trough type metal foam carrier catalytic bed solar energy absorption reaction device, which uses a metal foam material as the carrier of the catalyst bed. Background technique [0002] Energy is the basis for human survival and development. With the development and progress of human society, on the one hand, due to the need to improve living standards and promote social development, human demand for energy is increasing. On the other hand, the total amount of traditional fossil energy is limited. Regeneration, while the use of fossil energy is accompanied by serious pollutants and greenhouse gas emissions. The increasingly depleted fossil energy and the increasing energy demand of mankind, as well as the urgent requirements for environmental protection have formed sharp contradictions, which have seriously affected the sustainable...
