Air supplementing structure for combustor and non-woven fabric drying oven

Abstract

The utility model provides an air supplementing structure for a combustor and a non-woven fabric drying oven, the air supplementing structure for the combustor comprises a base, an air supplementing assembly and an air adjusting assembly, the base is fixedly installed at one end of the combustor in the horizontal direction, and an opening is formed in the position, corresponding to a through hole of the base, of the combustor so that the interior of the combustor can communicate with the exterior of the combustor; the air supplementing assembly comprises an air inlet pipe and a first baffle, the end, in the horizontal direction, of the air inlet pipe is arranged on the base and corresponds to the opening, the first baffle is installed at the other end of the air inlet pipe in a sealed mode, and a plurality of first air inlets are formed in the air inlet pipe in the circumferential direction; the air adjusting assembly comprises an air adjusting piece, the air adjusting piece is rotatably installed on the outer wall of the air inlet pipe, a plurality of second air inlets are formed in the air adjusting piece in the circumferential direction, the second air inlets correspond to the first air inlets in a one-to-one mode, the overlap ratio of the second air inlets and the first air inlets is adjusted through rotation of the air adjusting piece, and dynamic control over the air inlet amount is achieved. The combustion environment of the combustor is optimized, and the combustion efficiency is improved.
