Adsorbent bed system

Abstract

An adsorption bed system comprises two symmetrically-arranged adsorption beds of the same structure. The upper portions of the two adsorption beds are connected through an outlet pipe. The middle portions of the two adsorption beds communicate with each other. The lower portions of the two adsorption beds are connected with a fluid inlet channel through a fluid return channel and a fluid channel which are connected in parallel. Each adsorption bed comprises an adsorption bed steam ascent pipe, an adsorption bed upper partition, an adsorption bed heat exchange coil pipe and an adsorption bed lower partition, wherein the adsorption bed upper partition, the adsorption bed heat exchange coil pipe and the adsorption bed lower partition are sequentially arranged from top to bottom. The two ends of each adsorption bed heat exchange coil pipe are correspondingly and fixedly connected with the adsorption bed upper partition and the adsorption bed lower partition and correspondingly penetrate out of the adsorption bed upper partition and the adsorption bed lower partition. The adsorption bed steam ascent pipe penetrates the adsorption bed lower partition and the adsorption bed upper partition. According to the adsorption bed system, through phase-change heat transfer, the heat of the adsorption beds is recovered continuously, and the adsorption refrigerating efficiency is improved.

Description

technical field [0001] The invention relates to a technique in the field of adsorption refrigeration, in particular to an adsorption bed system. Background technique [0002] The Chinese government stated that by 2020, China's carbon dioxide emissions per unit of GDP (carbon emission intensity) will be significantly lower than in 2005. According to the "National Energy 13th Five-Year Plan", the proportion of non-fossil energy in China will increase from 12% in 2015 to 15% in 2020, an increase of 3 percentage points. At the same time, during the "13th Five-Year Plan" period, the energy consumption per unit of GDP has been reduced by 15%. Therefore, how to effectively use non-fossil energy and increase energy consumption in the industry has become a key technology that must be mastered to achieve the 13th Five-Year Goal. Among them, adsorption refrigeration technology is considered to be a very potential low-grade energy utilization technology. Because adsorption refrigerat...
