Built-in combustion heat supply structure of hydrogen energy device

Abstract

The invention discloses a built-in combustion heat supply structure of a hydrogen energy device in the field of reforming hydrogen production equipment to overcome the defects that an existing hydrogen energy heating device is small in radiation range and uneven in heat distribution, and in order to overcome the defects, according to the technical scheme, the built-in combustion heat supply structure comprises a heat exchanger, a combustion chamber and a battery pack which are sequentially connected from top to bottom; the two radial sides of the heat exchanger communicate with heat conduction pipes, the heat conduction pipes penetrate through the battery pack, the heat conduction pipes are tightly attached to the combustion cavity, and the heat conduction pipes are provided with flow guide heat efficiency devices in the airflow outlet direction. According to the technical scheme, the heat conduction pipe is tightly attached to the combustion chamber, heat is supplied through heat energy of waste gas, the preheating process of the combustion chamber is reduced, meanwhile, the heat radiation range of the combustion chamber is expanded through the heat conduction pipe, heat is evenly distributed, waste gas is further utilized, and therefore the utilization efficiency of the waste gas is improved.

Description

technical field [0001] The invention belongs to the field of reforming hydrogen production equipment, in particular to a hydrogen energy device built-in combustion heat supply structure. Background technique [0002] The concept of hydrogen energy economy was first proposed by John Bockris in 1970, aiming to use hydrogen as an energy carrier for vehicles (cars, boats, etc.) and portable electronic devices. The U.S. Department of Energy defines hydrogen energy as: hydrogen is an energy carrier rather than an energy source. It stores and transports energy in a usable form, but it must be prepared by extracting hydrogen-containing compounds. The total amount of hydrogen in nature is not large, and it needs to be prepared by using other energy sources and related technologies; in addition, the hydrogen produced is not directly used by users, but needs to be converted into electrical energy and then provided in the form of electricity to provide energy for users. .

AI Technical Summary

Problems solved by technology

[0004] The hydrogen energy device in the prior art mainly has the following defects. First, the reforming reaction zone in the reaction chamber is poorly heated, thereby affecting the reaction efficiency

2. The temperature inside the combustion cylinder and the bottom of the combustion cylinder is high, so the interlayer between the side walls above the bottom of the inner and outer cylinders can only be used as the reforming reaction zone, and the space of the reforming reaction zone is limited.

3. The preheating effect of gas and air is poor, and the combustion efficiency is relatively low
