What concentration of gas is not suitable for RTO furnaces

The concentration of combustible gas in the exhaust gas entering the RTO should be controlled below 25% of the lower limit value, otherwise it will not be suitable for RTO furnaces. Because when the concentration is too high, it is easy to cause RTO**, and fresh air should be used for dilution or exhaust gas should be exported to the equipment.

Moreover, the organic matter that is easy to react and polymerize should not be RTO, and the content of particulate matter in the gas should be controlled below 5 g m3, otherwise the regenerator is easy to block.

Halogen-containing waste gas should not be treated by RTO, because halogen-containing waste gas is easy to produce dioxin and other acid gases during the combustion process, which is easy to cause secondary pollution and serious corrosion to equipment.

Hope mine is helpful to the landlord.

There is no absolute standard for this. Generally, it does not matter if the concentration is high, and the safety problem can be solved by diluting the exhaust gas. Generally, dilution to 25% LeL is sufficient. What we do, it can be diluted up to 8-10 times.

RTO (Regenerative Thermal Oxidizer) mainly includes regenerative chambers, oxidation chambers, fans, etc., which absorb the heat of exhaust gas oxidation through the regenerative chamber, and use these heat to preheat the newly entered exhaust gas, so as to effectively reduce the heat emission after exhaust gas treatment, and at the same time save the heat loss when the exhaust gas is oxidized and heated, so that the exhaust gas maintains a high thermal efficiency (thermal efficiency of about 95%) in the high-temperature oxidation process, and its equipment is safe and reliable. It is easy to operate, easy to maintain, low operating cost and high VOCs removal rate.

The working principle of RTO is as follows: the organic waste gas is first preheated through the regenerator, and then enters the oxidation chamber, heated to about 800, so that the VOCs in the exhaust gas are oxidized and decomposed into CO2 and H2O; The oxidized high-heat gas is then heat treated in another regenerative chamber and then the flue gas is discharged from the RTO system. This process is constantly recycled, with each regenerator alternating between the mode of incoming exhaust gases and expelling the treated gases.

The switching time can be adjusted according to the actual situation. Regenerative thermal incinerator is suitable for treating ultra-large air volume and low concentration of exhaust gas device, through the way of heat storage and re-combustion to treat the exhaust gas, and finally produce CO2 and water, the treatment effect can generally reach more than 90%, as far as I know, most of the oil industry likes to use this equipment, because of the large demand for fuel, the oil industry can use local materials. RTO equipment is also very expensive, as long as the temperature is well controlled, dioxins will not be produced, and due to cost, such equipment has now been mostly replaced.

Most of the three methods commonly used to treat organic waste gas are activated carbon adsorption, incineration, and photolysis catalysis. There are pros and cons. You should choose the treatment method that suits you.

Control the combustion temperature to ensure that the residence time of the flue gas in the area where the temperature in the combustion chamber reaches more than 850 is not less than 2 seconds, so that the gas of the secondary combustion forms a swirl flow, so that the combustion is more complete and sufficient, and the dioxin can be fully decomposed. When the flue gas temperature drops to the range of 300 500, a small amount of dioxins that have been decomposed will be regenerated, therefore, the design considers to minimize the cross-sectional area of the tail of the waste heat boiler, so that the flue gas velocity is increased, so as to reduce the residence time of the flue gas from high temperature to low temperature, so as to reduce the regeneration of dioxins.

RTO stands for regenerative thermal incinerator, which is a high-efficiency organic waste gas treatment equipment. Its principle is to oxidize the organic matter in the exhaust gas into the corresponding carbon dioxide and water at high temperature, so as to purify the exhaust gas, and the heat released when the exhaust gas is decomposed, so that the thermal efficiency reaches more than 95%.

1. Types of exhaust gas applicable to RTO:

1. Alkanes, olefins, alcohols, ketones, ethers, esters, aromatics, benzene and other hydrocarbon organic waste gases.

2. The exhaust gas contains a variety of organic components, or the organic components change frequently.

3. Contains exhaust gas that is easy to poison the catalyst or decay the active force.

It can process almost all exhaust gases containing organic compounds.

2. Characteristics of RTO:

1. RTO can treat organic waste gas with large air volume and low concentration;

2. The elasticity of the flow rate of organic waste gas treated by RTO is very large;

3. RTO realizes self-heating operation without adding auxiliary fuel under the condition of suitable exhaust gas concentration.

RTO (RegenerativeThermal Oxidizer) is an abbreviation for Regenerative Exhaust Gas Treatment Device.

The working principle is to directly heat the organic waste gas to a high temperature of more than 760 and decompose it into CO2 and H20 in the oxidation chamber. The high-temperature flue gas generated after oxidation is heated and stored by the special honeycomb ceramic heat storage body, so that the furnace cavity is always maintained at a high working temperature, saving the fuel consumption of exhaust gas preheating and heating. The ceramic heat storage part is composed of two or more chambers, and the relatively clean gas after pyrolysis needs to be purged to ensure the removal rate of VOCs before entering the exhaust gas treatment system or directly discharging.

Hello, regenerative thermal oxidizer, abbreviated as RTO, includes a regenerative heat exchanger in the thermal oxidation unit, and the oxidation reaction can be carried out after the VOC preheating is completed. At this stage, the thermal rate of the regenerative thermal oxidizer has reached 95%, and its occupation is relatively small, and the consumption of auxiliary fuel is relatively small. Since current thermal storage materials can use ceramic fillers, they can handle corrosive or particulate VOC gases.

At this stage, the RTO device is divided into two types: rotary type and valve switching type, among them, the valve switching type is the most common one, which is composed of 2 or more ceramic filled beds, and the purpose of changing the direction of air flow is achieved by switching valves.

Shandong Jiyi Environmental Science and Technology believes that the difference between the two is that the RTO organic waste gas incinerator treats large air volume and low concentration of waste gas, and the waste gas element is diversified, and the regenerative incinerator is used in high concentration organic waste gas, in fact, both of these are to decompose the waste gas into water and carbon dioxide. To achieve the purpose of environmental waste gas treatment.

The working principle of waste gas treatment equipment.

The working principle of RTO is to heat the organic exhaust gas to more than 760 degrees Celsius (depending on the composition), so that the VOC in the exhaust gas is oxidized and decomposed into carbon dioxide and water. The high-temperature gas produced by oxidation flows through a special ceramic heat storage body, which heats up the ceramic body and "stores heat", which is used to preheat the organic waste gas that enters later. This saves fuel consumption for exhaust gas heating.

The ceramic regenerator should be divided into two (including two) or more, and each regenerator should go through the procedures of heat storage, heat release, cleaning and so on, and work continuously over and over again. After the regenerator is "exothermic", an appropriate amount of clean air should be introduced to clean the regenerator (to ensure that the VOC removal rate is above 98%), and only after the cleaning is completed can the "heat storage" procedure be entered. Otherwise, the residual VOCs are emitted to the chimney with the flue gas, thus reducing the treatment efficiency.

Advantages of exhaust gas treatment equipment.

1) Compact structure and small footprint.

2) High purification efficiency.

3) Energy saving.

4) The system pressure fluctuation is small.

5) No maintenance required for five years.

Application range of waste gas treatment equipment.

Waste gas treatment equipment is used in the coating production line industry.

Paint booth exhaust gas treatment program automobile coating produced organic waste gas is characterized by a large amount of exhaust gas, low VOCs concentration, if the direct use of thermal incineration oxidation treatment fuel consumption is very large, not environmentally friendly and economical, the current industry application of more purification methods is runner adsorption concentration and thermal incineration system, thermal incineration generally has 2 forms, ** thermal incineration system (TNV) and regenerative thermal incineration system (RTO), the system uses "adsorption, desorption, concentration and incineration" and other 3 continuous processes to deal with high flow, Low pollutant concentration and exhaust gas containing a variety of VOCs.

Which is the best RTO regenerative incinerator? How much? This is determined by your air volume and concentration as the main factors, the large air volume and high concentration will naturally require high investment in the EIA, and the low concentration and small air volume will be small and the natural cost will be small.

I recommend finding a manufacturer with rich professional experience, because this can reduce your time and cost, and can give you a lot of suggestions on how to solve the exhaust gas and meet the emission standards.

Personal suggestion: Now the state control environment is quite strict, at every turn is hundreds of thousands of fines, so environmental problems are extremely important in this regard, I suggest you look for manufacturers in Kunshan, Onison environmental protection company focuses on waste gas treatment, providing one-stop solutions, you can consider it.

1. All gas components are what you need to treat, and engineers analyze them, formulate solutions, and develop the required equipment to effectively reduce the exhaust gas composition and concentration.

It is recommended to consult Zhejiang Huantai Environmental Protection Equipment Co., Ltd., specializing in RTO projects.

In your case, the outlet temperature must be high. The heat storage layer does not store heat, and the most likely gap between the heat storage ceramics and the insulation cotton is too large, and the exhaust gas is taken away from the periphery of the heat storage ceramics, and the heat cannot enter the heat storage ceramics. Need to go to the content view.

Exhaust gases are not necessarily combustible and the products produced by some exhaust gases after combustion are still a source of pollution, which cannot be treated by combustion.

The composition of waste gas in chemical enterprises is relatively complex, generally multi-component mixed gas, and the exhaust gas emission concentration fluctuates very much, which is usually flammable, explosive, toxic and accompanied by odor, and is easy to pollute the surrounding environment. Based on the above characteristics, I recommend you RTO regenerative thermal oxidizer, which has the advantages of high thermal efficiency and low operating cost compared with traditional catalytic combustion and TO direct-fired thermal oxidation furnaces.

RTO refers to regenerative thermal oxidizer technology, that is, "regenerative thermal oxidizer".

RCO refers to regenerative catalytic oxidation oxidition.

The two work on different principles.

RTO regenerative thermal oxidation is a new unsteady state heat transfer method, the principle is to heat the organic waste gas to more than 760, so that the VOC in the waste gas oxidizes and decomposes into CO2 and H2O. The high-temperature gas produced by oxidation flows through a special ceramic heat storage body, which increases the temperature of the ceramic body, thereby "heat storage", which is used to preheat the organic waste gas entering later, saving the fuel consumption of the exhaust gas heating. RTO technology is suitable for treating low to medium concentration (100-3500mg m3) exhaust gas, and the decomposition efficiency is high, generally 95%-99%.

The principle of RCO regenerative catalytic combustion method is as follows: firstly, the adsorption of VOC molecules by the catalyst increases the concentration of reactants, and secondly, the activation energy of the reaction is reduced in the catalytic oxidation stage and the reaction rate is increased. With the help of catalyst, the organic waste gas can be decomposed into CO2 and H2O at a lower ignition temperature, and a large amount of heat is released, and the energy consumption is small, and in some cases there is no need for external heating after reaching the ignition temperature, and the reaction temperature is 250-400.
