<p>PROBLEM TO BE SOLVED: To provide a circulation heat storage type deodorizing device which is easy in maintenance, prevents the gas to be treated from being mixed in the treated gas, and is small in pressure loss. SOLUTION: A circulation heat storage type deodorizing device is provided with an outlet side heat storage zone S1 and an inlet side heat storage zone S2 to keep the granular heat storage body W above and below a combustion chamber 13 provided with a direct firing burner 14, and circulates the heat storage body to the outlet side, the inlet side heat storage zone, the circulation passage, and the outlet side heat storage zone by the circulation passage provided outside a device body 11, feeds the gas to be treated below the inlet side heat storage zone to burn the offensive odor substance in the combustion chamber, and discharges the treated gas above the outlet side heat storage zone. A part in the vicinity of the outlet of the heat storage body from the device body of the circulation passage is communicated with a part in the vicinity of the inlet of the heat storage body to the device body of the circulation passage through a seal material feed passage 27 to form a seal material circulation passage B with the circulation passage, a seal material Wa smaller in diameter than the heat storage body is fed, and a screen 28 having openings which is larger in diameter than the seal material and smaller in diameter than the heat storage body is provided at a connection part of the seal material feed passage and a part in the vicinity of the inlet of the circulation passage, is provided.</p> |
