Problems solved by technology

[0005] (1) Two sets of furnace burners are required, and two sets of fuel supply pipelines are required, which requires a large investment;
[0006] (2) There are obvious fluctuations in furnace temperature and pressure, which makes it difficult to control product quality;
[0007] (3) The combustion control device is complex
[0008] Rotary air preheaters currently use a large number of metal heat storage elements, which generally cannot withstand operating temperatures above 450°C

Abstract

The invention provides a rotary high-temperature air preheater which is characterized by comprising an outer frame, wherein a supporting cylinder, a rotor and a transmission gear are arranged in the outer frame; the rotor is positioned on the supporting cylinder; the transmission gear is positioned on one side of the supporting cylinder; the transmission gear is connected with the rotor; the rotor is provided with an upper cover; and the upper cover is connected with the outer frame through an expansion guide. The invention can be quickly assembled, and can allow a furnace with input of about1200 DEG C to discharge waste gas; and by using the preheater, the temperature of the output hot air can reach about 1000 DEG C to the maximum, and the temperature of the discharged waste gas is reduced to below 200 DEG C.

Description

[0001] This application is a divisional application of a rotary high-temperature air preheater. The filing date of the original application is October 21, 2009, the application number is: 200910197461.1, and the invention name is a rotary high-temperature air preheater. technical field [0002] The invention relates to a rotary high-temperature air preheater, which is used for waste heat recovery of various industrial kilns. The exhaust gas discharge temperature can be controlled below 200°C, and the maximum air heating temperature can reach about 1000°C. It belongs to the technical field of rotary heat exchangers , especially concerning high temperature component materials. Background technique [0003] Rotary air preheater is a mature equipment commonly used in large boiler systems. It utilizes heat accumulators (generally called rotors) that continuously pass through hot air and cold air to realize the continuous transfer of heat from hot air to cold air. [0004] At pres...
