Commutatorless high-temperature heat exchanger

Abstract

The invention relates to a commutatorless high-temperature heat exchanger. A heat storage device comprises a lower cylinder, a rotor heat storage body and an upper cylinder which are arranged in sequence, wherein the lower cylinder is fixedly arranged on a framework; the lower cylinder is partitioned into a low-temperature air chamber and a low-temperature gas chamber; a side face of the lower cylinder is provided with a low-temperature air inlet and a low-temperature gas outlet; the rotor heat storage body is supported against the lower cylinder in a free rotation manner and is filled with a heat storage medium; the upper cylinder is positioned on the rotor heat storage body and is fixedly arranged on the framework; the upper cylinder is partitioned into a high-temperature gas chamber and a high-temperature air chamber; the top of the upper cylinder is provided with a high-temperature gas inlet and a high-temperature air outlet; the high-temperature gas inlet in the upper cylinder is communicated with the low-temperature gas outlet in the lower cylinder; the low-temperature air inlet in the lower cylinder is communicated with the high-temperature air outlet in the upper cylinder; and a driving mechanism on the framework is in drive connection with the rotor heat storage body to drive the rotor heat storage body to rotate. The high-temperature gas heat is continuously transferred to combustion-supporting air by the rotation of the rotor heat storage body, so that thermal-state continuous operation and heat exchange are realized, and the heat exchange efficiency is high.

Description

technical field [0001] The invention relates to a non-reversing high-temperature heat exchanger, which is used for industrial kilns where hot water or steam is not used to recover heat. Background technique [0002] Regenerative high-temperature air combustion technology (HTAC) is a new concept of combustion technology that emerged in the late 1980s. It combines waste heat recovery with high-efficiency combustion and reduction of NO x Emissions and other technologies are organically combined to achieve energy saving and reduction of NO x Dual goals for emissions. With the advancement of equipment and materials, regenerative heat exchange technology has been widely used in heating furnaces and ladle bakers in metallurgical enterprises. However, while the technology holds great energy-saving potential, it also has some problems of its own. [0003] For example, in the non-ferrous metallurgy industry, the temperature in the furnace varies greatly due to its process character...

Problems solved by technology

This has not only caused unnecessary waste of fuel, but also increased the labor intensity of workers.

In the traditional reversing technology, the burners work in pairs, and each burner burns and exhausts alternately, which will inevitably cause fluctuations in furnace pressure, frequent phase changes, easy damage to the regulating valve, and failure alarms caused by unsuccessful ignition.

The failure of the combustion system caused by the failure of the reversing equipment directly affects the production, and there are certain safety hazards

For the intermittent reversing burner, the investment in the reversing part is increased. At the same time, if gas is used as fuel, the reversing of the combustion system also increases the operational risk of the operator. To solve this problem, considerable funds must be invested
