Incinerator manufacturers believe that as people's awareness of environmental protection continues to increase and the technology for heat recovery and other comprehensive utilization improves, the proportion of countries around the world using incineration technology to treat municipal waste is increasing year by year. The essence of incineration is to oxidize organic waste into inert gaseous substances and inorganic non-combustible materials under high temperatures and sufficient oxygen supply, forming stable solid residues.
IncineratorManufacturers believe that as people's awareness of environmental protection continues to increase and the technology for comprehensive utilization such as heat recovery improves, the proportion of countries around the world using incineration technology to treat municipal waste is increasing year by year. The essence of incineration is to oxidize organic waste into inert gas substances and inorganic non-combustible substances under high temperature and sufficient oxygen supply, forming stable solid residues. First, the waste is burned in rural municipal waste incinerators to release heat energy, and then the residual heat is recovered for heating or power generation. After purification, the flue gas is discharged, with a small amount of residual residue being discharged, buried, or used for other purposes. Its advantages include rapid volume reduction, complete harmlessness at high temperatures, small land area, minimal impact on the surrounding environment, and heat recovery.
RTOIncineratorIt is an efficient organic waste gas treatment device. Its working principle is to heat organic waste gas to above 760 degrees, causing the volatile organic compounds (VOCs) in the waste gas to oxidize and decompose into carbon dioxide and water.
The heat generated during the oxidation process is stored in a special ceramic heat storage body, raising the temperature of the heat storage body to 'heat storage'. The heat stored in the ceramic heat storage body is used to preheat subsequent organic waste gas, which is the 'exothermic' process of the ceramic heat storage body, thus saving fuel consumption during the waste gas heating process.
Requirements for waste gas in RTO incinerators:
1. The concentration of VOCs in the waste gas should be controlled below 25% of the lower explosion limit;
2. Suitable for large air volume and low concentration waste gas;
3. For acidic pollutants, most inorganic acids need to be removed first; it should not contain significant solids or dust, otherwise, pretreatment is required;
4. Mixing with harmful waste gases such as hydrogen, methane, and ethylene is prohibited.
Limitations of RTO incinerators:
1. The waste gas volume must not be suddenly discharged in excess; it cannot handle waste liquids, solid waste, or wastewater.
2. It cannot handle high-concentration harmful waste gases such as hydrogen waste gas, methane waste gas, corrosive waste gas, and ethylene waste gas.
3. Waste gas with LEL concentration exceeding 25% cannot be treated; otherwise, it needs to be diluted, but this will reduce the economic efficiency of incineration.
Characteristics of RTO incinerators in application;
1. Low concentration: The concentration of organic waste gas generated in industry is generally between 50-300 mg/m3. Reasonable use of RTO regenerative incinerators can help our waste gas meet discharge standards, which has also attracted attention from all sectors of society.
2. Complex composition: Many waste gases mainly come from solvents and diluents, including benzene, fatty substances, ketones, ethers, etc.
3. Huge air volume: Due to the different types and contents of waste gases produced by different products, RTO regenerative incinerators must be chosen carefully. If the selected RTO regenerative incinerator does not perform well, it will affect our production activities.Incinerator4. High relative humidity: Generally, wet varnish is used to remove some waste gas, and the organic waste gas discharged from it has a relatively high humidity.
