Description

Technical Field

[0001] This utility model belongs to the field of industrial waste gas treatment technology, and in particular relates to an industrial waste gas treatment device with waste heat recovery and utilization. Background Technology

[0002] When treating industrial waste gas, RTO (Regenerative Thermal Oxidizer) organic waste gas treatment equipment is generally used. The RTO combustion system is a high-efficiency device for treating organic waste gas and volatile organic compounds (VOCs). The RTO heats the waste gas through a regenerative ceramic body before combustion, which is beneficial for the recovery and utilization of combustion waste heat.

[0003] Existing industrial waste gas treatment devices with waste heat recovery and utilization systems, while using backflushing gas to clean the heat storage ceramic body, accumulate a large amount of impurities on the inner wall of the through holes after prolonged operation, and the ceramic body may even become blocked. Therefore, we propose an industrial waste gas treatment device with waste heat recovery and utilization. Utility Model Content

[0006] Based on the above structure, the pneumatic push cylinder drives the lifting slider to slide vertically along the inner wall of the active cleaning frame. The sliding of the lifting slider causes the limiting block on the outer wall of the lifting frame to slide along the outer wall of the limiting rod. The sliding of the lifting frame causes the insertion rod to slide relative to the through hole. The movement of the insertion rod pushes out the impurities on the inner wall of the through hole, realizing the cleaning operation of the heat storage ceramic body and greatly improving the service life of the heat storage ceramic body.

[0007] Preferably, the heat storage ceramic body is provided in three sets, and the three sets of heat storage ceramic bodies are distributed at equal intervals along the inner wall of the furnace. In this embodiment, by providing three sets of heat storage ceramic bodies, the heat storage combustion operation of the waste gas is realized, the waste heat is recovered and utilized, and energy consumption is greatly reduced.

[0008] Preferably, the through holes are distributed in a rectangular array along the outer wall of the heat storage ceramic body. In this embodiment, it is convenient for the waste gas to be heated to near the thermal oxidation temperature through the heat storage ceramic body, so as to realize the comprehensive heating operation of the waste gas.

[0009] Preferably, the lifting frame is parallel to the heat storage ceramic body. In this embodiment, this facilitates the sliding of the lifting frame to drive the insertion rod to slide relative to the through hole, thus preventing the insertion rod from deforming due to collision.

[0010] Preferably, the lifting frame forms a lifting structure through the lifting slider and the limiting rod. The limiting rod is parallel to the insertion rod. In this embodiment, the pneumatic push cylinder drives the lifting slider to slide vertically along the inner wall of the active cleaning frame.

[0025] In one embodiment, three sets of heat storage ceramic bodies 9 are provided, and the three sets of heat storage ceramic bodies 9 are distributed at equal intervals along the inner wall of the furnace body 5.
