Embodiment 1

[0032] The first embodiment of the present application provides a method such as figure 2 The fault self-detection module of the regenerative thermal oxidation device shown, the RTO furnace 5 is provided with a combustion chamber 6, a regenerator 1 7, a regenerator two 8 and a regenerator three 9, and the fault self-detection module includes: exhaust gas. LEL value measurement module 4, regenerator temperature measurement module 1, combustion chamber temperature control module 2 and poppet valve switching control module 3; an alarm counting module is also provided to count the accumulated times of different faults; the regenerator temperature measurement module 1 is connected to the poppet valve switching control module 3, used to balance the temperature of each regenerator; the regenerator temperature measurement module 1 includes temperature detectors set in regenerator one 7, regenerator two 8, and regenerator three 9. Thermometer T4, Thermometer T5 and Thermometer T6 plac...

Embodiment 2

[0038] On the basis of Example 1, as figure 1 As shown, the second embodiment of the present application provides a self-detection method for the fault self-detection module of the regenerative thermal oxidation device in the first embodiment, specifically:

[0039] The combustion chamber temperature control module is connected with the burner control module and the heat bypass control module, and is used for controlling the normal temperature of the combustion chamber. When the measured temperature value exceeds the working temperature value within 25 to 35 minutes, the alarm counting module will prompt an abnormal alarm in the combustion chamber. In the case of an abnormality alarm in the combustion chamber, further, in the case of no change in the feedback of the opening of the hot bypass valve, the alarm counting module will prompt the abnormality alarm of the hot bypass valve, and every 30 minutes, if the abnormality alarm of the hot bypass valve still exists, then Alarm...

Abstract

The invention relates to a fault self-detection module of a regenerative thermal oxidation device. The RTO furnace is provided with a combustion chamber, a regenerator first, a regenerator two and a regenerator three. The fault self-detection module includes: waste gas LEL value measurement module, regenerator temperature measurement module, combustion chamber temperature control module and lift valve switching control module; the regenerator temperature measurement module is connected with the lift valve switching control module for balancing the temperature of each regenerator. The beneficial effects of the present invention are: the present invention provides a fault self-detection module of a regenerative thermal oxidation device, through the interaction between each module, the cause of the fault can be predicted, and the accumulation of different faults can be further counted by the alarm counting module The number of times reduces the tedious work of on-site operators to ensure the safe and stable operation of the regenerative thermal oxidation device.

Description

technical field [0001] The invention belongs to the technical field of regenerative thermal oxidation devices, in particular to a fault self-detection module and method of a regenerative thermal oxidation device. Background technique [0002] Regenerative thermal oxidation furnace is a way to solve volatile organic compound (VOCs) waste gas, which is widely used in coal chemical industry. The sample gas at the end of the methanol washing process in the coal chemical industry has low oxygen concentration and high organic matter concentration. The regenerative thermal oxidation device can fully burn the exhaust gas, so that the flue gas emission can meet the environmental protection requirements. The abnormality of the regenerative combustion device will cause the exhaust gas emission to fail to meet the environmental protection requirements. Seriously, the regenerative thermal oxidation device may explode. Therefore, the safety of the regenerative thermal oxidation device it...
