Problems solved by technology

[0002] Existing devices for oxidation treatment of waste gas often do not effectively use the waste heat generated by the waste gas after combustion, either directly discharge the heat to the outside, or only extensively recycle the heat, and the utilization rate of waste heat as a whole is relatively low. Low, poor environmental protection
[0003] The defects in the prior art include but are not limited to: 1. The existing devices cannot effectively utilize the waste heat of the exhaust gas after oxidation treatment, and the utilization rate of the waste heat is low; 2. Most of the existing heat storage devices use heat storage ceramics bed, but the regenerative ceramic bed is prone to clogging after long-term use, and needs to be shut down frequently for cleaning. In traditional equipment, back-flushing is usually done after one-time feeding and combustion of exhaust gas, and additional time is required at this time 3. Theoretically, the higher the temperature of the regenerative ceramic bed after absorbing the waste heat of the exhaust gas, the better the preheating effect on the new exhaust gas. However, if the regenerative ceramic bed If the temperature continues to increase, it may exceed the maximum tolerance value of the heat storage ceramics, which will cause damage to the heat storage ceramics

Embodiment 1

[0043] When the device is in use, two different directions of air intake-outlet are operated as a group. In the first treatment, valve one 111, valve seven 371, valve eight 381, and valve three 131 are all opened. The other valves are in the closed state, and the normal temperature exhaust gas enters the first chamber 801 through the first air duct 11, and then passes through the ventilation hole 601 in the first ceramic heat storage bed 5 with a higher temperature to realize preheating, and then enters the second chamber 801. The chamber 802 enters the combustion chamber 36 from the first guide pipe 37. At this time, an open flame will be ejected from the combustion nozzle 41. After the exhaust gas is burned, the temperature of the exhaust gas after treatment is relatively high, and the high-temperature gas passes through the second The draft pipe 38 enters the fourth chamber 902, and enters the third chamber 901 through the ventilation hole 601 on the second ceramic heat stor...

Embodiment 2

[0047] During the use of Embodiment 1, the ventilation holes 601 of the first ceramic regenerator bed 5 or the second ceramic regenerator bed 6 can be regularly back-purged, which can be divided into two situations, namely, the first ceramic regenerator The temperature of the heat bed 5 or the second ceramic regenerator bed 6 itself does not exceed or has exceeded the maximum tolerance value, and in this embodiment, the temperature does not exceed the maximum tolerance value.

[0048] Specifically, taking the first treatment in the first embodiment above as an example, when the exhaust gas blows to the second chamber 802 through the first ceramic heat storage bed 5, the first cylinder 25 and the second cylinder 26 shrink downward at the same time, The hydraulic cylinder 21 shrinks and drives the push plate 22 to move, and then pumps the preheated gas into the inner cavity of the outer frame body 20, and then reversely activates the second cylinder 26, so that the second cylinde...

Embodiment 3

[0050] During the use of Embodiment 1, the ventilation holes 601 of the first ceramic regenerator bed 5 or the second ceramic regenerator bed 6 can be regularly back-purged, which can be divided into two situations, namely, the first ceramic regenerator The temperature of the heat bed 5 or the second ceramic regenerator bed 6 itself has not exceeded or has exceeded the maximum tolerance value, and in this embodiment, the temperature has exceeded the maximum tolerance value.

[0051] Specifically, taking the first treatment in the first embodiment above as an example, when the exhaust gas blows to the second chamber 802 through the first ceramic heat storage bed 5, the isolation plate 28 is in the position of connecting the second chamber 802 and the outer frame In the state where the inner cavity of 20 is isolated, if the temperature of the gas in the second chamber 802 is too high, the heat-sensitive expansion joint 35 will be heated and expanded, and then the trigger plate 34...

Abstract

The invention discloses an intelligent heat accumulating type oxidation device for reducing carbon emission through waste heat recovery. The intelligent heat accumulating type oxidation device comprises a shell, a first ceramic heat accumulating bed and a second ceramic heat accumulating bed are the same in structure and are both provided with ventilation holes, a plurality of air gathering covers are fixedly embedded in a mounting plate, an air distribution plate is fixedly arranged at an output end of a first air cylinder, a separation plate is fixedly arranged at an output end of a second air cylinder, a normal-temperature air inlet pipe is arranged at the bottom of an outer frame body in a communicating mode, and concave blocks are attached to the side walls of the first ceramic heat accumulating bed and the second ceramic heat accumulating bed. According to the intelligent heat accumulating type oxidation device for reducing carbon emission through waste heat recovery, the waste heat utilization rate is high, back flushing does not occupy normal treatment time, the waste gas treatment efficiency is effectively improved, and back flushing gas at different temperatures can be utilized to effectively avoid the situation that the ceramic heat accumulating bed is damaged due to the fact that the ceramic heat accumulating bed exceeds a temperature tolerance value.
