Problems solved by technology
In order to save incineration costs, regenerative incineration methods are mostly used. For example, Chinese patent CN01207962.6 discloses a regenerative incinerator for organic waste gas, which uses two regenerative beds to alternately switch modes to complete gas temperature rise, purification and heat storage. However, when the double heat storage bed incinerator switches the heat storage bed, the gas to be treated in the preheated heat storage bed will be discharged because it is not incinerated, so there will be periodic untreated gas cross-pollution emission problem

The invention provides heat-accumulation-type catalytic combustion equipment. The equipment comprises a heat-accumulation catalytic furnace and a preset number of adsorption units, wherein the heat-accumulation catalytic furnace comprises a first heat-accumulation catalytic chamber and a second heat-accumulation catalytic chamber, the first heat-accumulation catalytic chamber and the second heat-accumulation catalytic chamber are subjected to switching through a rotary switching valve to select the sequence for waste gas to enter the first heat-accumulation catalytic chamber and the second heat-accumulation catalytic chamber, and the adsorption units are used for adsorbing organic matter left in a pipeline and a heat-accumulation catalytic area in the switching process so as to avoid thatperiodic untreated gas causes cross contamination when discharged. According to the equipment, the feature that the industrial organic waste gas is combusted at low temperature on the surfaces of catalysts is utilized in combination with the feature that heat accumulators utilize heat, and therefore, the utilization rate of heat is increased while the industrial organic waste gas is purified.
Description
technical field [0001] The invention relates to waste gas treatment equipment, in particular to a regenerative catalytic combustion equipment. Background technique [0002] It is a very effective treatment method to treat organic waste gas or odor by incineration. Its principle is to use high heat to directly oxidize the organic matter in the waste gas composition into CO 2 and H 2 O. In order to save incineration costs, regenerative incineration methods are mostly used. For example, Chinese patent CN01207962.6 discloses a regenerative incinerator for organic waste gas, which uses two regenerative beds to alternately switch modes to complete gas temperature rise, purification and heat storage. However, when the double heat storage bed incinerator switches the heat storage bed, the gas to be treated in the preheated heat storage bed will be discharged because it is not incinerated, so there will be periodic untreated gas cross-pollution The issue of emissions.
