Abstract

The invention discloses a combined type high-efficiency air preheater and a preheating method thereof, and belongs to the technical field of air preheaters. Gas or liquid needing to be preheated is guided into a spiral preheating guide-in pipe and sealed through a valve, and high-temperature smoke exhausted by a boiler is connected through a connecting disc; high-temperature smoke enters a hollow oval heat exchange bin through a telescopic pipe and an air guide pipe, flows in the hollow oval heat exchange bin after entering the hollow oval heat exchange bin and reaches a first trapezoid plate; and if the temperature detected by a first temperature sensor mounted on the first trapezoidal plate is higher than the temperature detected by a second temperature sensor mounted at the tail part of the spiral preheating ingress pipe, the first valve and the second valve are opened, and the valve leading to the filter bin is closed.

Description

technical field [0001] The present invention relates to an air preheater, in particular to a combined high-efficiency air preheater. The thermal method belongs to the technical field of air preheaters. Background technique [0002] The air preheater is a heat exchanger that uses the exhaust heat of boilers and other devices to preheat. [0003] Its function is to reduce the exhaust gas temperature of boilers and other equipment, improve thermal efficiency, make fuel easy to ignite, burn stably and improve combustion efficiency. [0004] In the prior art, there are the following problems when using the air preheater: [0005] 1. The shell structure design of the air preheater is unreasonable and cannot achieve the function of automatic cycle preheating, and it is often a one-way cylinder structure; [0006] 2. The filter structure of the air preheater in the prior art does not have a good energy-saving cleaning structure, resulting in waste of energy; [0007] 3. In the p...
