REGENERATIVE COMBUSTION APPARATUS WITH ROTARY VALVE HAVING IMPROVED SEALING IN SWITCHING FLOW DIRECTION

The present invention relates to a regenerative combustion apparatus including a rotary valve with improved sealing at the time of switching a wind flow direction. According to the objective of the present invention, the level of a sealing plate installed at a lower portion of the regenerative combustion apparatus to maintain a gap from a rotary valve is automatically adjusted by a gel-type flowing sealant; and a purge air discharge structure of the rotary valve positioned at the lower portion of a diffuser plate and rotating is modified not to mix inflow air and exhaust gas. The regenerative combustion apparatus processing a volatile organic compound (VOC) includes a diffuser plate (110) which has a sealing plate (31) inserted into a sealing hole (113) formed in the top surface, and a leak blocking baffle (117) protruding from the bottom surface in a circumferential direction, and fills the sealing hole with a gel-type flowing sealant (32) to make the level of the sealing plate uniform; and an air sealing unit (131) which has fanwise sealing holes (111) formed in each lateral end of a dead zone (250) and a purge zone (260) in a longitudinal direction, and, in a circumferential direction, an air pocket (4023) with a plurality of fine purge holes (4022) arranged at a position opposite to the leak blocking baffle (117) to block leak gas.
