1) initial engine; from the air valve inlet, open the burner; use small air volume and fresh air preheating rto storage layer, to meet the demand of temperature, through the process of waste gas. after 1 preheating process of waste gas regenerator, the temperature in the combustion chamber is raised to 760 deg c, the oxidation of energy release, if the gas concentration is higher without adding fuel; if the concentration is not enough, you need to add extra fuel, the combustion chamber temperature is maintained in the decomposition temperature of demand. the process organic waste gas is decomposed into h20 and co2, through the regenerator 2 and the heat exchange of the regenerator 2 and the high temperature gas, the temperature is stored in the regenerator 2. the exhaust gas passes through the regenerator 2 and goes to the chimney.
2) the temperature of the regenerator 2 will slowly increase, and the regenerator 1 temperature will decrease slowly. when the regenerator 1 temperature is less than the exhaust gas preheating demand (the temperature of the outlet air below the regenerator). then the lifting valve is switched, the regenerator 2 and the regenerator 3 are used, and the gas is successively through the regenerator 2 and the regenerator room 3 to complete the oxidation decomposition process.
3) through the position control of the switch valve, when the regenerator 2,3 works, the negative pressure is formed in the regenerator 1, and the undecomposed exhaust gas remaining in the regenerator is pumped to the front end of the main fan to enter the system for reburning. the whole process is completed in a negative pressure system without exhaust gas leakage. the treatment efficiency is more than 99%.
4) the regenerator 1,2,3 passes through the switching valve and restores the heat around the regenerator; the heat release; the process of cleaning, and the decomposition of the organic waste gas continuously.
introduction of rto regenerative incinerator
the coke oven gas direct combustion of organic waste gas regenerative incinerator, at the temperature of 750-850 deg c, the organic molecule is decomposed into co2 and h2o, flue gas after combustion with regenerative heat accumulated in the ceramic ceramic tile, preheating of organic waste gas, and then exhaust emissions, import direction by switching valve automatic switching, cycle work, rto can fully recover the combustion heat decomposition, greatly reduce the energy consumption of the system.
the organic waste gas is decomposed into harmless co2 and h2o by oxidation of the voc component in the exhaust gas through the high temperature zone of the rto oxidation chamber. the reaction equation:
the heat of the high temperature gas after oxidation is stored up by the ceramic heat storage body to preheat the newly entered organic waste gas, thus saving fuel and reducing the cost of use.
rto process flow:
the first cycle (as above):
c: organic waste gas into the regenerator regenerator of c ceramics after fan regenerator (ceramic regenerator "storage" on a cycle of heat at high temperature), the ceramic regenerator heat release, temperature, and organic gas absorbing heat, temperature, exhaust gas through the regenerator for c after the heat to high temperature oxidation into the room.
room: after oxidation of organic waste ceramic regenerator c after heat exchange in high temperature chamber into the oxidation reaction, the oxidation of organic compounds into harmless co2 and h2o, such as the temperature of the exhaust gas does not reach the oxidation temperature, the heating burner directly to the oxidation temperature compensation, the exhaust gas has in the regenerator of c preheating, enter the oxidation chamber only slightly heating can reach the oxidation temperature (if the gas concentration is high enough, the oxidation can not require natural gas heating, by the oxidation of organic matter decomposition heat can maintain spontaneous combustion, high temperature oxidation gas) after discharge a ceramic regenerator.
regenerator a: high temperature oxidized gas into the chamber a (this time in the low temperature ceramic state), high temperature gas to release a lot of heat regenerative ceramic a, gas cooling, and ceramic regenerator a absorb a large amount of heat after heating storage (for the next cycle of organic waste gas preheating), the effect of the gas blower from the chimney into the atmosphere, the exhaust temperature than the high inlet air temperature of about 40 deg c.
regenerator b: b ceramic regenerator in a clean state, a cycle ends when the valve is switched between the valve and the regenerator in the bottom of the b has a small amount of waste gas, a small amount of hot gas chamber by oxidation the purge to the main fan inlet and exhaust gas into the organic ceramic regenerator c.
the second cycle: exhaust gas from the regenerator room a, the regenerator b discharge, the regenerator c for back blowing;
the third cycle: exhaust gas from the regenerator room b, the regenerator c discharge, the regenerator a for back blowing;
so it turns round and turns alternately.
