Heat accumulating type heat exchanger

Abstract

The invention belongs to the technical field of industrial heat exchange equipment, and provides a four-channel heat accumulating type heat exchanger which saves more energy, can work continuously and is suitable for all heat furnace types. The heat accumulating type heat exchanger comprises a smoke outlet, a hot air combustor, heat exchanger bodies, an air blower and a chimney, the smoke outlet and the hot air combustor are arranged on an industrial furnace, one ends of the heat exchanger bodies are communicated with the smoke outlet and the hot air combustor which are arranged on the industrial furnace, the other ends of the heat exchanger bodies are communicated with the air blower and the chimney, the four heat exchanger bodies are connected in parallel, one end of each heat exchanger body is respectively communicated with the smoke outlet and the hot air combustor through a vent pipeline and a reversing valve, the other end of each heat exchanger body is respectively communicated with the air blower and the chimney through a vent pipeline and a reversing valve, an induced draught fan is arranged on a vent pipeline on the front portion of the chimney, honeycomb heat accumulating bodies are arranged in the heat exchanger bodies, and thermometers used for displaying temperature and remote transmission thermometers used for controlling switching valves are arranged on the vent pipelines. The heat accumulating type heat exchanger is mainly applied to industrial heat exchange aspects.

Description

technical field [0001] The invention relates to a regenerative heat exchanger, which belongs to the technical field of industrial heat exchange equipment. Background technique [0002] Various furnace thermal equipment heated by flames are widely used in the industrial field. These equipment must burn fuel when realizing their technological purposes, and also produce a large amount of waste medium and high-temperature flue gas. These high-temperature flue gases will be discharged while being discharged Take away a large amount of energy, so recycling these energy has extensive and far-reaching application value. [0003] At present, there are two main types of conventional combustion flue gas waste heat recovery devices in China: one is an air preheater, and the other is a reversing heat storage device. [0004] Conventional air preheaters mainly include partition wall type and heat pipe type. Regardless of the type, there are problems such as small heat transfer surface ar...

Problems solved by technology

However, the existing regenerative heat exchanger cannot work continuously, and the exchange stops every few minutes before re-igniting. When the direction is reversed, the supply of combustion hot air is interrupted, which is likely to cause backfire and increase the risk. Moreover, it burns a single fuel, and the usable range is narrow. Therefore, it is necessary to improve
