1. A staggered and crossed heat storage adsorption bed, comprising a bed body, wherein an adsorption cavity is arranged in the bed body; two sides of the adsorption cavity are respectively communicated with an inlet cavity and an outlet cavity; the adsorption cavity comprises a vacuum heat insulation layer arranged at an outermost side; and the vacuum heat insulation layer is embedded with an adsorption box fixing layer inside;
a corner end adsorption box, a central adsorption box and a side adsorption box are staggered and crossed arranged in an inner cavity of the vacuum heat insulation layer through the adsorption box fixing layer; and the corner end adsorption box, the central adsorption box and the side adsorption box are all used for filling adsorption substrates;
the adsorption cavity comprises a dry-hot gas first enters a first layer adsorption formed by the corner end adsorption box and the central adsorption box from the inlet cavity, and then diffuses along an airflow direction to enter a second layer adsorption formed by the side adsorption box; the first layer adsorption and the second layer adsorption adjacent to it form an adsorption group; the dry-hot gas flows out of the outlet cavity after circulating and alternating through a plurality of adsorption groups;
the adsorption box fixing layer comprises a plurality of baffles perpendicular to an inner wall of the vacuum heat insulation layer; and
the inner cavity of the vacuum heat insulation layer is a regular polygon structure; the corner end adsorption box is arranged at an included angle of adjacent inner walls of the vacuum heat insulation layer, and the corner end adsorption box is fixedly arranged between two baffles with the shortest distance between the adjacent inner walls of the vacuum heat insulation layer; a shared side of a plurality of corner end adsorption boxes closest to the center of the inner cavity of the vacuum heat insulation layer is fixedly provided with the central adsorption box through the baffle; and the central adsorption box and the corner end adsorption boxes are arranged on a same end face; a peripheral wall of the central adsorption box is sequentially staggered and crossed with a side adsorption box through the baffles; each side of the corner end adsorption box, the central adsorption box and the side adsorption box is a hollow metal mesh surface.
