Description

A air supply structure and non-woven fabrics oven for combustor Technical Field The utility model relates to the technical field of textiles, in particular to an air supplementing structure for a combustor and a non-woven fabric oven. Background Nonwoven fabrics (nonwoven fabrics) are widely used in medical, sanitary, filter materials and industrial fields due to their excellent breathability, filterability and lightweight properties. In the heat treatment link of the non-woven fabric, the oven equipment is key equipment for realizing rapid dehydration, shaping and stable performance of the non-woven fabric. Such devices often employ a heated air circulation system, wherein the heat source is typically provided by a burner. In the existing burner structure, a forced air supply combustion mode is generally adopted, namely, air is sent into the burner by a blower, and is mixed with fuel for combustion. However, in actual operation, combustion efficiency, flame stability, and heat energy transfer efficiency are still limited by the degree of air-fuel mixing and the air flow conditions of the combustion zone. If the air flow rate, mixing ratio or combustion zone pressure distribution is controlled improperly, the combustion performance is poor. In order to improve combustion performance, part of the technical schemes introduce a wind supplementing structure for guiding external air into a combustion area so as to optimize the combustion environment. However, most of traditional air supplementing modes adopt a form of opening holes or a simple air guide pipe, the air inlet amount is fixed, and the dynamic regulation and control capability is lacked, so that the air flow structure is unreasonable, and the phenomena of low air supplementing efficiency, main flame disturbance and the like are caused.
