Description

Heat accumulating type oxidation furnace with dust removal function

Technical Field

The utility model relates to the technical field of oxidizing furnaces, in particular to a heat accumulating type oxidizing furnace with a dust removing function.

Background

A Regenerative Thermal Oxidation (RTO) furnace, which oxidizes organic matters (VOCs) in exhaust gas to corresponding carbon dioxide and water at high temperature, thereby purifying the exhaust gas and recovering heat released when the exhaust gas is decomposed. The RTO main body structure consists of a combustion chamber, a regenerative chamber, a switching valve and the like. RTO theory of operation: firstly, organic waste gas is preheated by a regenerator and then enters an oxidation chamber, and the temperature is raised to about 800 ℃ by heating, so that VOCs in the waste gas are oxidized and decomposed into carbon dioxide and water; the oxidized high-heat gas is subjected to heat treatment through another regenerator, and then the flue gas is discharged out of the RTO system. The process is continuously cycled through regeneration, with each regenerator alternately switching between modes of input exhaust and exhaust process gas. The switching time can be adjusted according to the actual situation. The waste gas contains low-concentration malodorous pollutant organic matters, the oxidation and decomposition are carried out according to the oxidation chamber, the temperature of the flue gas reaches about 800 ℃, the organic components in the waste gas are subjected to oxidation and decomposition, then the high-temperature flue gas enters another group of heat storage chambers to exchange heat with the heat storage ceramic filler, and the flue gas after heat exchange enters a spray washing tower through an induced draft fan to be washed and finally enters a chimney to reach the standard to be discharged to the atmosphere.
