The working principle of the high-efficiency environment-friendly multi-kettle mobile plant carbonization furnace in the embodiment is specifically explained as follows:
the solid waste to be pyrolyzed at low temperature is put into the low-temperature carbonization furnace 102 from the feeding port of the crushing feeder 106, and the crushing feeder 106 crushes the solid waste and then feeds the crushed solid waste into the discharging port. After the solid waste is ignited, wet straw is pressed on the solid waste, and the carbonization effect is prevented from being influenced by excessive air.
Flue gas generated in the carbonization process is conveyed into a flue gas filter 201 through an air conveying chute 103, the flue gas filtered by the flue gas filter 201 enters a double alkali spray tower 202 through a smoke discharge pressure pipeline 206 under the action of a negative pressure machine 203, and dust in the flue gas is contacted with water drops and sinks in the double alkali spray tower 202 and falls into a circulating water tank 302; the water in the double alkali spray tower 202 is pumped by the centrifugal water pump 303 from the water source in the circulating water tank 302, and the water in the double alkali spray tower 202 falling into the circulating water tank 302 can be pumped into the double alkali spray tower by the centrifugal water pump 303 again for recycling.
The purified flue gas enters the water seal device 204 through an external pipeline and enters the activated carbon adsorber 205 from the outlet of the water seal device 204, and in the activated carbon adsorber 205, the toxic gas in the purified flue gas is further adsorbed by activated carbon, so that air pollution is avoided.
In addition, when flue gas that the carbonization in-process produced passes through exhaust pipe 206, thermometer 207 can show its temperature in real time, when the temperature value exceeded 120 ℃, switches on centrifugal water pump 303 and cooling water pipe 104's connection, and centrifugal water pump 303 pumps the water source in circulating water tank 302 into cooling water pipe 104 and sprays to low temperature carbonization stove 102 through the shower nozzle, and it is that carbonization temperature control is in 80-120 ℃ within range, after the temperature is stabilized in this within range, blocks centrifugal water pump 303 and cooling water pipe 104's connection. The water source sprayed by the cooling water pipeline 104 enters the bottom of the low-temperature carbonization furnace 102, is conveyed to the flue gas filter 201 through the air conveying chute 103, finally flows out of the water outlet of the flue gas filter 201, and then enters the circulating water tank 302 through the external pipeline, so that the recycling of the water source is realized.
