Embodiment 1

[0025] Such as figure 1 , figure 2 and image 3, an integral structure for adsorption thermochemical energy storage and building heating, including a gas main inlet 1, a valve 2, a gas inlet branch pipe section 3, an energy storage reaction bed 4, a gas outlet branch pipe section 5, and a gas main outlet section 6. Steering valve 7, gas outdoor outlet section 8, gas indoor outlet section 9, pipeline heat insulation layer 10, bolt 11, threaded hole 12. The gas inlet and outlet sections are both cylindrical pipes, and the general inlet section is used to connect the dry hot air or wet cold air pipes provided by the outside. The diameter of the reaction bed pipe connected to the gas branch pipe at both ends is not smaller than the diameter of the branch pipe. In order to improve the utilization rate of the incoming gas and ensure that the solid reactant reacts with the gas as much as possible, the diameter of the reaction bed pipe is 1 to 4 times the diameter of the branch pi...

Abstract

The invention discloses an integrated structure for adsorption thermochemical energy-storage and building heating. The integrated structure comprises a main gas inlet section, a valve, a gas inlet branch section, an energy-storage reaction bed, a gas outlet branch pipe section, a main gas outlet section, a turning valve, a gas outdoor outlet section, a gas indoor outlet section and a pipeline thermal insulation layer. The integrated structure is used for heat storage and release of the gas-solid adsorption/desorption type energy-storage reaction process. Each section of the reaction bed is formed by filling of a solid reactant, and the periphery of a pipeline is wrapped by a thermal insulation material, so that heat loss during reaction is reduced. The integrated structure comprises a gasconveying pipeline and the energy-storage reaction bed, the space size of a heat-storage heat-supply device is reduced, the problems of solid reactant local excessive adsorption air-slaking, incomplete reaction and the like are avoided, the heat and mass transfer effect in the gas-solid reaction process is improved advantageously, an heat storage unit is directly combined with the gas conveying pipeline, the device is simple and reliable, and the feasibility of chemical heat storage on the aspect of building heating or heat supply is improved.

Description

technical field [0001] The invention relates to the technical field of thermochemical energy storage and building heating, in particular to an integral structure for adsorption thermochemical energy storage and building heating. Background technique [0002] Energy is the material basis of human activities. The continuous development and utilization of energy has promoted the development of human civilization. As the energy crisis becomes more and more serious, various energy-saving and emission-reduction measures are being continuously developed and applied. In today's energy consumption, building energy consumption is the most significant, accounting for about 1 / 3 of the country's total energy consumption. In order to use energy more rationally and efficiently, it is extremely necessary to store and convert heat effectively. Compared with sensible heat and latent heat storage, thermochemical heat storage has higher energy density and can be used for cross-seasonal heat ...
