Rotor Concentrator / incinerator RotorConcentrator / Oxidizer
Rotor Concentrator / incinerator system adsorption air volume low concentration of volatile organic compounds (VOCs). After a small amount of wind then desorbed gas is introduced into a high concentration of incinerators decomposition purification. Low wind concentration of VOCs emissions, by a zeolite adsorbent material for the wheel, VOCs are adsorbed by the zeolite after adsorption zone runner purified gas to the atmosphere through the chimney, and then by desorption zone at 180 ℃ ~ a small amount of hot air 200 ℃ will be desorbed VOCs. Such a high concentration of small amounts of desorbed gas in the air introduced into the incinerator to be decomposed into carbon dioxide and water vapor, purified gas through the chimney into the atmosphere. The enrichment process greatly reduced fuel costs.
The catalyst of chlorinated organics incinerator
Chlorinated organics catalyst incinerator (ChlorinatedCatalyticOxidizer) system by air flow, contaminant species and required removal efficiency and design.
When you run the operation by the exhaust gas catalyst of chlorinated organics incinerator blower system containing VOCs evacuated heat exchanger. Pipe-side exhaust gas through the heat exchanger, to the burner, where the catalyst is heated to the reaction temperature of the exhaust gas. Exhaust gases containing VOCs by a special anti-halide catalyst poisoning, into carbon dioxide, water vapor and emit heat. This hot purified gas through the shell side of the heat exchanger, the exhaust gas heat heating immersion systems, so fuel costs can be reduced to a minimum, in many cases, such as VOCs concentration is high enough, you can no additional fuel system to run itself . Finally, if necessary, can be installed Anguil scrubber to remove inorganic acid (such as HCL, CL2, HBr, Br2, etc.). Hydrogen chloride suit scrubber (HCLScrubberModule), gaseous hydrogen chloride suit scrubber outlet containing HCL or CL2 introducing hydrogen chloride suit scrubber quench tower, circulating mercury injection amount of water entering with superalloy (Hastelloy) Material quench tower ( quenches). Then the water will cool the hot exhaust gases and hydrogen chloride to be absorbed part, after a stretch through the tract into the counterflow absorber. Circulating the absorption solution from the absorber spray nozzle at the top, fully absorb the remaining hydrogen chloride, and then a layer to remove water droplets removed, then vented to the atmosphere.
Ceramic Filter automatic clean-up system
Automatic clean-up ceramic filter system (Self-cleaningCeramicFilter) exhaust system according to the amount and types of pollutants required to fill and filtration efficiency related. Operating system is running, exhaust gas from the process (cold or hot containing organic particulate matter / organic coagulant substance or VOCs). By evacuating to the ceramic filter. Example path through the exhaust gas according to the size and the size of the particulate matter collection efficiency of the design chosen ceramic plate, a burner, a batch or a continuous heating the ceramic plates that trapped here a ceramic plate and volatile organic particulate matter into the incinerator and be collected by any of the inorganic ashes and inorganic burned off to the bottom of the cavity. By volatile organic compounds lead to the incinerator (catalyst incinerator, direct-fired incinerator) by incineration is converted to carbon dioxide, water vapor and heat.
RTO Regenerative Thermal Oxidizer
Emissions from process exhaust gases containing VOCs into the double slot RTO, three-way switching valve (POPPETVALVE) this gas is introduced into the storage tank RTO (EnergyRecoveryChamber) and preheat the exhaust gas, containing contaminated waste gas is gradually heated regenerative ceramic block after entering the combustion chamber (CombustionChamber), VOCs are oxidized in the combustion chamber and heat energy is released in the second heat storage tank of the ceramic block, to reduce the consumption of auxiliary fuel. Ceramic block is heated, clean combustion gas after oxidation gradually lowering the temperature, so the outlet temperature slightly higher than the RTO inlet temperature. Three-way switching valve is switched to change the RTO outlet / inlet temperature. If VOCs concentration is high enough, the released heat enough, RTO ie without fuel. For example RTO heat recovery efficiency of 95%, RTO inlet temperature higher than the export only 25 ℃ only.
Regenerative catalyst incinerator (RCO)
Emissions from process exhaust gases containing VOCs into the double slot RCO, three-way switching valve (POPPETVALVE) this gas is introduced into the storage tank RCO (EnergyRecoveryChamber) and preheat the exhaust gas, containing contaminated waste gas is gradually heated regenerative ceramic block after entering the catalytic bed (CatalystBed), VOCs by decomposition catalyst in the oxidation of heat energy is released in the second heat storage tank of the ceramic block, to reduce the consumption of auxiliary fuel. Ceramic block is heated, clean combustion gas after oxidation gradually lowering the temperature, so the outlet temperature slightly higher than the inlet temperature of the RCO. Three-way switching valve is switched to change the RCO outlet / inlet temperature. If VOCs concentration is high enough, the released heat enough, RCO ie without fuel. For example RCO heat recovery efficiency of 95%, RCO export only higher than the inlet temperature is 25 ℃ only.
The catalyst incinerator CatalyticOxidizer
The catalyst incinerator is designed according to the exhaust air flow, VOCs concentration and destruction removal efficiency required to be known. Operation with exhaust gas heat exchanger into the system within the wind turbine system containing the VOCs, after the exhaust gas is heated by the heat exchanger tube side (Tubeside), then through the burner, then the exhaust gas had been heated to a temperature of the catalytic decomposition, and then by catalyst bed catalytic decomposition releases heat, and VOCs are decomposed into carbon dioxide and water vapor. After a hot and purified gas into the shell side of the heat exchanger (shellside) heating the tube VOC exhaust side (tubeside) untreated, this heat exchanger will reduce energy consumption, and finally, purified gas from the chimney vented to the atmosphere.
Direct-fired incinerator is designed according to the exhaust air flow, VOCs concentration and destruction removal efficiency required to be known. Operation with exhaust gas heat exchanger into the system within the wind turbine system containing the VOCs, after the exhaust gas is heated by the heat exchanger tube side (Tubeside), then through the burner, when the exhaust gas has been heated to the catalytic decomposition temperature (650 ~ 1000 ℃), and sufficient retention time (0.5 to 2.0 seconds). Then undergo thermal reactions, and VOCs are decomposed into carbon dioxide and water vapor. After a hot and purified gas into the shell side of the heat exchanger (shellside) the tube side (tubeside) untreated VOC gas heating, the heat exchanger will reduce energy consumption (more than adequate even certain VOCs concentration when they do not need additional fuel), and finally, purified gas from the chimney into the atmosphere.
Direct fired incinerator DirectFiredThermalOxidizer-DFTO
Sometimes directly from the combustion incinerator afterburner (After-Burner), direct fired incinerator using specially designed burners to heat the exhaust gas to a high concentration ㄧ preset temperature, when in operation the exhaust gas is introduced into the combustion chamber (BurnerChamber ). Burner VOCs and toxic air pollutants decomposed into non-toxic substances (carbon dioxide and water) and release heat, the gas can be further purified by a heat recovery system to achieve energy needs.
