Entry-level type apparatus for regenerative thermal oxidation process

摘要

The present invention divides (2n+1) heat storage chambers inside the heat storage unit casing, inserts and fills a breathable heat storage material for each heat storage chamber, and assembles a combustion chamber casing providing a combustion chamber at the upper end of the heat storage unit casing. On the other hand, at the lower end of the heat storage unit casing, a windbox is assembled in which a blow pipe for harmful gas through each heat storage chamber and an exhaust pipe for clean gas passing through a heat storage material and a purge pipe for removing residual air are connected, and the blower pipe and the exhaust pipe The and purge pipe relates to a heat storage combustion oxidation treatment apparatus equipped with an automatic opening/closing valve mechanism that alternately performs the inflow of harmful gas, the discharge of clean gas, and the supply of purge air for each heat storage chamber. The box and the heat storage unit casing are manufactured in the shape of a square tank, and the (2n+1) spaces that are partitioned inside are arranged in the left and right directions using a diaphragm, and the blower pipe and the exhaust pipe are (2n+1) spaces. The purge pipe is connected to the front inlet side and the rear outlet side of the windbox so as to be allocated one for each space, while the purge pipe is connected one by one for each outlet position of the blower pipe. Compared with the existing method that was arranged with the valve mechanism, the production, installation, and maintenance of the device can be performed very easily and quickly, while the rational and economical method is a popular type that allows the treatment efficiency of harmful gases to be at the same level as the existing one. It relates to a heat storage combustion oxidation treatment device.
