Refuse incineration rotary kiln
Product introduction: Rotary incineration kiln is widely used in industrial waste treatment incineration equipment, in the industrial waste incineration market share is high, as the incineration of hazardous waste this specific industry, rotary incineration kiln to deal with complex industrial waste, such as stable and reliable operation, easy management and operation, equipment maintenance and other advantages, to achieve garbage harmless, reduction, resources.
Applicable materials: industrial waste, garbage, hazardous waste, etc
Waste incineration rotary kiln product introduction
Rotary kiln incineration kiln is a mature technology, if the waste to be treated contains a variety of difficult to burn substances, or the moisture range of the waste is large, rotary kiln is a more ideal choice. Rotary kiln can handle a wide range of waste, especially in the incineration of industrial waste is widely used. The application of waste incineration in raw materials is mainly to improve the burning-out rate of slag and burn up the waste to meet the quality requirements of slag reuse. After waste incineration treatment, it can achieve reduction, resource, harmless, save land, and achieve the purpose of waste resource.
Outstanding advantage
1, low cost: high temperature materials contact refractory materials, easy to replace the lining;
2, transmission mechanism is simple: transmission mechanism in the kiln shell, equipment maintenance is simple;
3, to ensure that harmful gases do not leak: good sealing measures and furnace negative pressure;
4, easy operation and maintenance: high equipment operation rate;
5. Strong adaptability to incineration: solid waste and liquid can be incinerated at the same time;
6, high heat utilization rate: incineration material billowing forward.
Working principle
Waste incineration rotary kiln can handle solid and liquid waste at the same time, solid waste is sent to the rotary kiln by special conveying equipment, liquid waste is sprayed into the kiln body feed end through atomization equipment, waste in the rotary kiln to complete the process of water evaporation, volatilization analysis, fire and combustion, ash part is discharged from the bottom of the secondary combustion chamber, the generated flue gas into the secondary combustion chamber. Mixed with the secondary combustion air in the secondary combustion chamber to achieve complete combustion of the flue gas and achieve the safety emission of the tail gas.
Three incineration methods of rotary kiln are ash and slag incineration. Slag incineration; Pyrolytic incineration.
1. Ash and slag incineration in rotary kiln
Ash and slag incinerator, the temperature of the rotary kiln is controlled at 800℃ -900 ℃, and the hazardous waste is destroyed by oxidation melting. The main discharge from the tail of the rotary kiln is ash and slag, which is loose after cooling. Due to the low temperature of the furnace, the high-temperature erosion and oxidation of hazardous waste on the refractory materials of the rotary kiln are not strong, so the service life of refractory materials is relatively long. The phenomenon of "hanging wall" in the inner furnace body is not serious.
2, rotary kiln slag incineration
Slag rotary kiln incinerator is mainly to deal with some single, highly toxic hazardous waste, the temperature is generally above 1500℃, the purpose is to improve the destruction rate. Because the objects treated are different, the composition is complex, and the melting point of some hazardous wastes is above 1300℃ -1400 ℃, the temperature control of this type of incinerator is difficult and the operation requirements are high. Due to the high furnace temperature of slag rotary kiln incinerator, the consumption of auxiliary fuel increases, resulting in higher fuel consumption, mechanical loss and operation difficulty of refractory and thermal insulation materials in rotary kiln.
3, rotary kiln pyrolysis incineration
The temperature in the kiln of pyrolytic rotary kiln is controlled at 700℃ -800 ℃. Due to the combustible gas generated by the pyrolysis and gasification of hazardous waste in the rotary kiln into the secondary combustion chamber, the oil consumption can be greatly reduced. In addition, due to the low temperature, less heat loss, the smoke volume is relatively low in the three processing processes, and the installed capacity is reduced and the operating cost is greatly reduced. However, its disadvantage is that the ash residue residue is high, ash residue incineration is not complete, some key technologies have been broken through, this incineration method represents the development direction of rotary kiln incineration hazardous waste technology, especially for resource-saving society, this is particularly important.
