Problems solved by technology

Through a large number of experimental tests, it can be seen that the solid residue of low-temperature pyrolysis still has a considerable calorific value, but the method of recovering the waste heat of solid residue, using fluidized combustion low-value energy residue as a heat source, and thermal cracking in a rotary furnace has not been used so far. see the report
Because rubber and plastic can obtain a high oil yield, and the pyrolysis oil has a high calorific value, it can be used as fuel or chemical raw material, and has broad prospects. Therefore, domestic and foreign research on waste pyrolysis oil production is mainly Separate pyrolysis of garbage such as plastics and waste rubber. However, the pyrolysis of plastics and waste rubber has some different characteristics. Refractory synthetic polymers such as plastics and waste rubber are different from municipal solid waste. During the process, different components may interact to reduce the pyrolysis efficiency. Therefore, it is urgent to design a waste pyrolysis oil treatment equipment for pyrolyzing waste, especially refractory waste, and waste pyrolysis oil. Methods

Embodiment 1

[0025] The garbage pyrolysis oil production equipment in this embodiment includes a rotary furnace, and the rotary furnace includes a feeder 1, a hopper 2, a rotary furnace chamber 6, a discharge bin 22, an oil condenser 10, and the bottom of the oil condenser 10 connected in sequence An oil outlet 12 is provided, and the oil condenser 10 is connected with the exhaust pipe I25, and also includes a fluidized furnace, which includes a fluidized furnace cavity 7 and an air supply device and a smoke exhaust pipeline II20 connected thereto. The interface is provided with a comb-shaped sealing device 8, the bottom of the fluidized furnace cavity 7 is provided with a gas nozzle 24 and an air distribution plate 14, and the lower layer of the air distribution plate 14 is an air chamber; the fluidized furnace cavity 7 is provided with a material return port and an air return port. The port is connected with the bottom of the discharge bin 22 through the return pipe 13, and the return por...

Embodiment 2

[0033] Except for the following differences, the others are the same as in Embodiment 1: the feeder 1 is a screw feeder, which is suitable for garbage treatment with a particle size greater than 30 mm and less than or equal to 50 mm, and the rotary kiln 6 is inclined downward by 8° as a whole.

[0034] The calorific value of the ash and slag falling from the rotary furnace chamber 6 is about 16MJ / kg, which is suitable for the fuel of the boiling furnace chamber 7; the pyrolysis oil collected after the pyrolysis gas enters the oil condenser 10 contains only 5-8% of water, and the calorific value reaches 36MJ / kg kg, the oil yield is about 40%, which is related to the proportion of plastic and rubber in the mixed garbage. The larger the rubber ratio, the higher the oil yield and calorific value.

Description

technical field [0001] The invention belongs to the technical field of energy preparation equipment, and in particular relates to a garbage pyrolysis oil production treatment equipment which can pyrolyze garbage, especially refractory garbage, into fuel oil. Background technique [0002] With the rapid development of modern industry and the improvement of people's living standards, the types and quantities of municipal solid waste are increasing day by day. In particular, synthetic polymer waste mainly composed of rubber and plastic is not easy to degrade in nature, and it is easy to cause serious pollution to the natural environment. Utilization method and pyrolysis method, among which pyrolysis method is divided into gasification pyrolysis and liquefaction pyrolysis. The centralized landfill method is the most commonly used method, and the garbage is buried deep underground, but the refractory garbage such as synthetic polymer garbage exists underground for a long time, p...
