If the flow to be treated is below 5000Nm3/h, the regenerative system (RTO) is generally not applicable. This is due to the high cost of regenerative oxidizer (RTO) compared to the thermal incineration system, in general, is insufficient to offset the benefits of fuel saving and power consumption. When the flow rate is greater than 50000Nm3/h, the thermal and thermal incineration system has serious economic disadvantages, because they will produce very high fuel costs. However, if the process requires a large amount of heat energy, the two stage hot boiler can be used to offset the high fuel costs, and the other exception is the annual operation of the system, the need to deal with large flow of waste gas emergency system.
If the treatment of organic waste gas temperature above about 300 DEG C, is not suitable for the use of regenerative system (RTO), this is because of the high temperature treating organic waste gas will reduce the reliability and life of the valve greatly; in addition, in such a high temperature, high into the construction of RTO is not enough to offset the in saving fuel and electricity consumption benefits. If the treatment of organic waste gas temperature more than 500 DEG C, the heat recovery type incineration system as the use of direct fired incineration system, because the fuel consumption gap is too small, not enough to offset the increase in heat recovery from investment cost.
The direct fired oxidizer is able to handle the maximum concentration range of hydrocarbons from 1/1000000000 concentration levels to pure hydrocarbon vapors. If the concentration of organic waste gas is more than 25%, special consideration should be taken to prevent the oxidation from the oxidizer to the source. The cost of this ability to handle a large concentration range is the high fuel cost of this type of oxidizer.
Special care must be taken when organic waste gas contains a high concentration of organic acids (such as chlorine, fluorine, sulfur and halogen). They will cause serious corrosion to the equipment or poisoning the catalyst.
Special care must be taken when organic waste gases contain tiny particles. For example, when the exhaust contains oil mist particles, they will gather in the pipeline and the cooler parts of the oxidizer, the device needs to be cleaned regularly.
Can the principle of choice for organic waste gas treatment system based on your device, if the oxidation of two or more types are suitable for you to use, let us do the running cost a type based on the investment cost and equipment for you (catalyst, fuel and power costs) with economic analysis, to help you make the best the choice of. If the flow rate of organic waste gas is less than 5000Nm3/h, the regenerative system (RTO) is not applicable in general. This is due to the high cost of regenerative oxidizer (RTO) compared to the heat recovery incineration system, in general, is insufficient to offset the benefits of fuel saving and power consumption.
Organic waste gas treatment tower is a new type of gas purification equipment. The utility model is improved on the basis of the floating filler layer gas purifier, which is widely used in the treatment of industrial waste gas purification and dust removal, and the purification effect is good. Because its working principle is similar to the washing process.
The washing tower is composed of a tower body and a tower plate, reboiler and condenser. In the process of using the reboiler is generally steam heating, the condenser with circulating water heat conduction. Before use should establish a balance that pass into the product group than in pure with steam and condensed water regulating the evaporation and the back flow, which can accumulate a certain thickness of the liquid in the tray, when the gas components can quickly pass into the washing effect. In the use of the process to control a liquid level, two temperature and two pressure points and other points. That is, the level of the washing tower, gas inlet temperature, tower top temperature, the pressure difference between the tower (the difference between the inlet pressure of the washing tower and the top pressure), the condenser pressure difference (the difference between the top and the condenser outlet pressure).
