The high-temperature gas after the partial purification leaves the combustion chamber and enters the heat storage cavity B which is cooled in the previous cycle. The gas releases heat, the heat is discharged after being cooled, and the heat storage cavity B absorbs a large amount of heat and then is heated, and the absorbed heat is used for heating the waste gas in the next cycle. At the same time, the induced draft fan extracts a little trace organic gas remained in the previous cycle from the heat storage cavity C, returns to the inlet of the induced draft fan, and then is sent into the combustion chamber for burning, and the partial gas and the treated gas leave the heat storage cavity B together and are discharged into the atmosphere.
After the cycle is completed, the input valve and the output valve are switched once to enter the next cycle. The waste gas enters from the heat storage cavity B, is sent into the ceramic dielectric layer of the heat storage cavity B by a high-pressure induced draft fan, and after the last circulation heat is reserved, the organic waste gas absorbs heat and enters into the combustion chamber at a higher temperature to prepare for oxidization. In the combustion chamber, the organic waste gas is heated and combusted by the burner, and the temperature is raised to the set oxidation temperature, and at the moment, the temperature is also set to 800 ℃, so that the organic matters are decomposed into carbon dioxide and water to be discharged. A little of trace organic gas remained in the heat accumulation cavity A in the previous cycle is pumped out by an exhaust gas induced draft fan and then sent to a combustion chamber for burning, and the part of gas leaves the heat accumulation cavity C together with the treated gas and is discharged into the atmosphere. The oxidation reaction of the exhaust gas is performed by alternately circulating the above steps.
Through the switching of the input and output valves of different heat storage cavities, the direction of the waste gas entering the preheating chamber is changed, and the alternating conversion of the heat storage area and the heat release area is realized. When the concentration of the VOCs (volatile organic compounds) in the system is high enough and the heat energy emitted is high enough, the combustion chamber can maintain the oxidative decomposition condition of the VOCs without fuel, and meanwhile, the waste heat of the system can be output to the outside. A. The temperature of the heat storage cavities B gradually decreases from top to bottom, the heat storage cavities A, B, C are switched according to the period T, and the treated flue gas enters an exhaust gas discharge pipe.

The filter material is composed of 25-stage primary and medium-efficiency filters, and the dust purification rate of more than 5um in the gas is not less than 95%.
In a preferred embodiment of the utility model, the cyclone degreasing device further comprises a cleaning system, wherein the cleaning system comprises a fan, a heater (such as an infrared radiation heating plate HDRQ, HRA-L and the like), a humidifier (such as E2441A, DEM-F600 and the like) and a ventilation pipe. The fan is communicated with one end of the ventilation pipe, the heater and the humidifier are both arranged in the ventilation pipe, the humidifier is positioned on one side of the heater close to the fan, the air outlet of the ventilation pipe is communicated with the waste gas conveying pipe, and the air inlet of the ventilation pipe is communicated with one or more of the waste gas discharge pipe, the cyclone dehydration deoiler or the dry filter.
And the cleaning system is utilized to introduce heated high-temperature steam into the waste gas conveying pipe, so that the waste gas discharge pipe, the cyclone dehydration deoiler or the dry filter can be deoiled at high temperature regularly, and the potential safety hazard is reduced. The air speed of the fan can be adjusted according to the requirements, the cleaning air quantity is increased, the inside of the back blowing equipment is purged with asphalt organic matters adhered to the wall surface of the box body and the wall of the pipeline, and the asphalt organic matters are burnt and decomposed into harmless substances of carbon dioxide and water outside the combustion chamber hearth or the equipment, so that the pollution-free emission is realized, the natural gas consumption during the original cleaning can be reduced, and the pollution-free emission reaching standard can be ensured within 24 hours.
In a preferred scheme of the utility model, the cyclone oil removal equipment also comprises a security system, wherein the security system comprises a leakage detection pressure switch (such as a pressure sensor and the like), a flame detector (such as an ultraviolet flame detector), a explosion venting sheet (HG/T20570.3, a pressure release installation device consisting of the existing low-pressure explosion venting sheet can be adopted), an electromagnetic valve and a flame arrester (backfire preventer). The leakage detection pressure switch is arranged in the combustion chamber, the explosion venting sheet is arranged on the side wall of the combustion chamber, and the leakage detection pressure switch is electrically connected with the control end of the explosion venting sheet.

The metal corrugated strip is provided with a certain gap according to the size of the corrugation, and the gap is generally between 0.2 and 0.7 mm. Two or more metal corrugated strips are typically used and are contained within an anti-riot housing to form a flame arrester. When a flame passes through such a metal corrugated strip, heat is quickly absorbed and dissipated, thereby lowering the temperature of the combustion products, which falls below the self-ignition point of the gas.
The leakage detection pressure switch is used for detecting pressure information in the combustion chamber, and if the pressure information exceeds a normal range, the leakage detection pressure switch can control the starting of the explosion venting piece to release pressure, so that damage to system equipment is reduced. The flame detector senses the flame of the burner, and when the burner burns normally, a flame signal shows that the electromagnetic valve of the fuel supply pipeline is closed when no flame exists; when the combustion flame is extinguished, the electromagnetic valve in the fuel supply pipeline is automatically closed to cut off fuel, so that the safety protection effect is achieved. The flame arrester can block the backfire of the combustion system, only allows the waste gas to pass through, and can inhibit the propagation of flame.
