Hydrogen storing tank based on metal hydrogen storage principle

Abstract

The invention discloses a hydrogen storing tank, which has good safety and high hydrogen-storing density, is developed based on a meal hydrogen-storing principle and is favorable for solving the technical problems of poor safety, large energy consumption, low hydrogen-storing density and the like of the prior art for hydrogen storage. The hydrogen storing tank comprises a pressure storing tank, a hydrogen input port and a hydrogen output port, wherein the hydrogen input port and the hydrogen output port are arranged on the pressure storing tank, an input-end control valve is arranged on the hydrogen input port; and output-end control valve is arranged on the hydrogen output port; a plurality of powdery hydrogen-storing alloys are filled in the pressure storing tank; a plurality of heating pipe bundles are embedded in the hydrogen-storing alloys; the heating pipe bundles are fixed on a fin group in a penetration way and are connected with an electric heater power supply outside the pressure storing tank; a cooling water pipe is arranged on the fin group corresponding to the peripheries of the heating pipe bundles; two ends of the cooling water pipe extend to the outside of the pressure storing tank and are connected with a cooling water system; and the electric heater power supply, the input-end control valve and the output-end control valve are connected onto a control system.

Description

technical field [0001] The invention relates to a hydrogen storage tank, in particular to a hydrogen storage tank with good safety and high hydrogen storage density based on the principle of metal hydrogen storage. Background technique [0002] With the development and use of traditional energy sources such as oil and natural gas, the resulting environmental pollution is becoming more and more serious. At the same time, due to the limited storage of traditional energy sources such as oil and natural gas, the development and application of new energy sources is a challenge faced by all mankind. of a subject. Hydrogen is the most common element in nature, and its resources can be said to be endless. It has the advantages of high calorific value and no pollution. Hydrogen storage is an important link in the utilization of hydrogen energy. The existing hydrogen storage methods are generally divided into gaseous hydrogen storage and liquid hydrogen storage. Hydrogen storage is ...
