Control system of organic waste gas catalytic burner and operation method of control system

Abstract

The invention discloses a control system of an organic waste gas catalytic burner and an operation method of the control system. The control system comprises a central controller, a configuration storage, a collection module, a control module and an execution mechanism; the configuration storage, the collection module, the control module and the execution mechanism are all connected to the central controller; the collection module comprises a temperature collection module, a concentration collection module, a valve collection module and a wind amount collection module, the control module comprises a heating module, a valve module, a wind amount module and an alarm module; the execution mechanism comprises a catalysis chamber, a reversing valve, a draught fan, an air inlet valve, an emergency valve and an alarm device; a control system and a waste gas inlet and outlet mode of a traditional organic waste gas catalytic burner are changed, through the circular air inlet and outlet manner of multiple burners, the influence of heat generated by waste gas in the combustion process on a catalyst in the burner can be thoroughly avoided, the generated energy is led into a heat storage chamber of the burner to be preheated through a pipeline in a gas inlet and outlet manner, and the energy utilization rate is high.

Description

technical field [0001] The invention relates to the field of organic waste gas treatment devices, in particular to a control system for an organic waste gas catalytic burner. Background technique [0002] Organic waste gas (Volatile Organic Compounds, referred to as VOC) is one of the main pollution sources of the atmospheric environment. Due to its high toxicity, it is very harmful to human health, especially benzene and polycyclic aromatic hydrocarbons, which violate the human nervous, respiratory, blood and reproductive systems, causing dizziness, dizziness, and nausea in mild cases, and causing Aplastic anemia, leukemia, and cancer are life-threatening, so treatment is urgently needed. [0003] Catalytic combustion is one of the conventional methods for treating organic waste gas, which converts organic waste gas into harmless gas through catalytic reaction and combustion; for conventional catalytic combustion devices on the market, the normal working temperature of the...

AI Technical Summary

Problems solved by technology

[0003] Catalytic combustion is one of the conventional methods for treating organic waste gas, which converts organic waste gas into harmless gas through catalytic reaction and combustion; for conventional catalytic combustion devices on the market, the normal working temperature of the catalytic bed is 250-850 ℃, lower than 250 ℃, the purification effect of the catalyst is poor, and the emission standard cannot be met; when the working temperature of the catalytic bed is higher than 800 ℃, the service life of the catalyst will decrease, and the catalyst will be damaged if the temperature exceeds 850 ℃, so that the equipment will lose its catalytic purification ability; The catalytic combustion of organic waste gas in the catalytic chamber is to release heat, and the released heat can easily raise the temperature in the catalytic chamber to above 850°C; therefore, ordinary catalytic combustion equipment needs to stop working after working for a period of time, and the device must be carried out. Time cooling maintenance, which seriously affects the working efficiency of the device, which is not conducive to the continuous industrial production of enterprises

Moreover, even if other backup equipment is used to process organic waste gas during cooling and maintenance, the cooling process is also a process of losing heat and wasting energy.
