[0062] When the integrated RTO is working, the organic exhaust gas is processed into the ceramic heat storage body 420 of the first heat storage chamber 421 (the ceramic medium "stores" has the heat of the previous cycle), the ceramic release heat, the temperature is lowered, and the organic exhaust gas absorbs The heat, the temperature increases, and the exhaust gas leaves the first heat storage chamber 421 to enter the combustion chamber 41 at a higher temperature, at which time the high low of the exhaust gas temperature depends on the geometric structure of the ceramic body volume, the exhaust gas flow rate and the ceramic regeneration 420. In the combustion chamber 41, the organic exhaust gas is then heated by the combustor 481 to a set oxidation temperature of 760 ° C, so that the VOC component is decomposed into carbon dioxide and water. Since the exhaust gas has preheated in the heat storage chamber 42, the fuel consumption is greatly reduced. There are two functions of the combustion chamber 41: First, it is ensured that the exhaust gas can reach the set oxidation temperature, and the second is to ensure that there is sufficient residence time to sufficiently oxidize the VOC in the exhaust gas. The exhaust gas incinerates in the combustion chamber 41, which is a purified high temperature gas away from the combustion chamber 41, and enters the second heat storage chamber 421 (which has been cooled in the previous cycle), and the heat is released, while the second heat storage The cavity 421 absorbs a large amount of heat after heating (for the next circulation heating, exhaust gas). The purified exhaust gas is discharged into the atmosphere by the chimney, and the minimal stock purification gas cleans the first heat storage chamber 421. The exhaust temperature is about 40 ° C higher than the intake air temperature. After the cycle is completed, the first valve 45 is switched with the second valve 46 to enter the next cycle, and the exhaust gas is entered by the second heat storage chamber 421, and the third heat storage chamber 421 is discharged. At the same time, a part of the purified gas cleaning first heat storage chamber 421, the week, and continuously.
[0063] The working principle of the present invention is: 1) The organic exhaust gas generated by the production workshop 7 enters the multi-stage dry filter for pre-treatment, dust removal rate is ≥99%; the new wind supplement device 1 to the production workshop 7 to replenish the new wind, new wind supplements The amount is less than or equal to the air volume discharged through the exhaust chimney; 2) Adsorption concentration treatment in the zeolite drum 3 after pre-treatment, the VOC purification rate is ≥95%, and the cleansing gas after being adsorbed by the zeolite drum 3 ( Volatile organic content less than 20 mg / m 3 , Even lower, such as production space volatile organic matter applications applied to manual operations less than 7mg / m 3 ) After the main fan 5 is discharged into the exhaust tab, the rest is re-delivered to the production workshop 7; 3) Using the small air amount of the small air generated by integrated RTO High-temperature exhaust gas to remove the VOCs molecules on the partially zeolite drum 3, The high concentration of exhaust gas formed is fully combined with a total of RTO to obtain a purification gas, a VOC purification rate> 99%, and some purifying gas is discharged into the atmosphere.
[0064] The exhaust gas in this application program has been treated with the standard. Most of the reuse pipe replenish the production workshop, the reuse can reach more than 70%, even more than 90%, so that the new wind system only needs to add a small amount of fresh air (supplement fresh) The air volume exhaust emissions is ≤30%, even ≤10%) to meet the requirements of the production workshop, and directly discharged directly from the existing exhaust gas processing system directly discharged directly through the new wind system. You can use a new wind system for smaller power, reduce new wind system investment costs and operating costs (reducing the energy consumption and consumables cost of new wind systems); at the same time, due to only a small amount of exhaust emissions in production workshops (exhaust gas emissions ≤ 30%, even ≤10% ), It is also possible to significantly reduce exhaust emissions, reduce exhaust emissions costs.
