Industrial waste gas heat storage combustion device

The invention relates to the technical field of heat accumulating type combustion, and discloses an industrial waste gas heat accumulating type combustion device which comprises a furnace body, a combustion cavity and three decomposition chambers are arranged in the furnace body, and heat accumulators are installed in the three decomposition chambers; the treatment device is used for carrying out energy utilization and recovery on waste gas in the furnace body and carrying out pressure back-flushing cleaning on a heat accumulator in the furnace body; and the conversion device is used for automatically changing the position of the heat accumulator and carrying out closed energy storage. According to the industrial waste gas heat storage combustion device, the heat storage body can be automatically rotated by an angle through the arranged conversion device when the combustion device runs, so that the heat storage body is in an up-and-down vertical state, waste gas can be conveniently input, decomposed and combu
