[0002] At present, solid waste is mainly composed of industrial solid waste and domestic solid waste, and the output is in a state of continuous increase, which causes serious pollution to the environment. Especially hazardous solid waste, if it is not treated scientifically, it is likely to damage the surrounding environment. At present, there are more than 70 types of hazardous solid waste in the "National List of Hazardous Wastes" promulgated by my country. In addition, hazardous solid waste is highly toxic and is likely to cause corrosion. In other words, hazardous solid waste is not only diverse in type, but also highly harmful. If hazardous solid waste is discharged directly without treatment, it will cause serious harm to the surrounding ecological environment. Therefore, it must be treated before it can be discharged.

[0003] There are various methods for treating hazardous solid waste, which can be generally divided into the following four methods. The first is chemical method, the second is physical method, the third is biological treatment method, and the fourth is stabilization solidification method. These methods are all used to change the properties of toxic substances in hazardous waste from the perspective of physical chemistry to achieve harmlessness. However, secondary pollution is easily caused during the treatment process, and generally only the treatment of harmful substances is considered, and resource recovery and utilization are not achieved, resulting in a certain degree of resource waste.

The synthesis gas processing module includes a quenching dust removal device 7, a condenser 8, a washing tower 9, an induced draft fan 10 and a rack synthesis gas outlet 11. The melting furnace exhaust port on the upper part of the high-temperature plasma melting furnace 3 is connected to the tangential air inlet on the upper part of the quenching dust collector 7, the top air outlet of the quenching dust collector 7 is connected to the hot side inlet of the condenser 8, the hot side outlet of the condenser 8 is connected to the lower air inlet of the washing tower 9, the top air outlet of the washing tower 9 is connected to the inlet of the induced draft fan 10, and the outlet of the induced draft fan 10 is connected to the rack synthesis gas outlet 11.

[0039] A central tube is provided at the top center of the quench dust removal device 7. The upper end of the central tube is the top air outlet of the quench dust removal device 7. The lower end of the central tube extends to the lower part of the inner cavity of the quench dust removal device 7. After the combustible synthesis gas enters the inner cavity of the quench dust removal device 7 from the tangential air inlet, it rotates at high speed along the annular space between the outer periphery of the central tube and the inner wall of the quench dust removal device 7. Under the action of centrifugal force, larger particles are thrown inside the dust removal device and settle. An atomizing nozzle is provided at the upper part of the inner cavity of the quench dust removal device 7 to atomize the cooling water, and then the combustible synthesis gas is sprayed for cooling and dust removal. The quench dust removal device 7 is provided with a water outlet for recycling cooling waste water and circulating spraying. When the concentration is too high, it can be discharged into the sewage treatment station for treatment.

[0040] A spray pipe is provided at the top of the washing tower 9, and a plurality of atomizing nozzles are installed on the spray pipe.

The other is connected to the synthesis gas processing module, including the quenching dust removal device 7, the condenser 8, the washing tower 9, the induced draft fan 10 and the rack synthesis gas outlet 11.

[0042] The conveying device transfers hazardous solid waste into the feeding device 2 through the solid waste rack entrance 1, and the feeding device 2 continuously presses it into the high-temperature plasma melting furnace 3. A sealing device is provided at the entrance of the furnace to prevent the synthesis gas from escaping from the feeding port.

[0043] A plasma torch 4 is installed on the top of the high-temperature plasma melting furnace 3, and the power of the plasma torch 4 can be appropriately adjusted according to the feedback of the control system. The lower end of the plasma torch 4 is inserted into the lower part of the furnace of the high-temperature plasma melting furnace 3, and a crucible 5 is provided at the bottom of the furnace. The crucible 5 is used to hold the slag-like hazardous solid waste transported into the furnace by the feeding device 2, and is the main place for the thermal cracking of hazardous solid waste under the plasma torch 4. A guide groove is provided on the outer periphery of the crucible 5 to guide the molten hazardous solid waste to flow into the slag storage chamber 6, and a molten material discharge port is provided at the bottom of the slag storage chamber 6 to discharge the molten material in the slag storage chamber 6. The hazardous solid waste is melted into a liquid state under the plasma torch 4. When the molten liquid material overflows the upper edge of the crucible 5, it will flow into the slag storage chamber 6 below along the guide groove to prevent the slag from accumulating in the furnace and slagging. The hazardous solid waste that is not completely melted will continue to remain in the crucible 5 until it is completely melted and cracked.

[0044] A filter screen plate 13 is provided in the middle of the height direction of the cooling water tank 12. The slag enters the cooling water tank 12 and falls on the filter screen plate 13 to become an inert and stable glass body after cooling. The circulating water pump 15 continuously extracts clean water under the filter screen plate 13 and sends it to the upper part of the cooling water tank 12 for circulation. The fixed end of the filter screen plate 13 is hinged to the side wall of the cooling water tank 12, and the other end of the filter screen plate 13 is a free end. A telescopic rod 14 is hinged at the lower middle part of the filter screen plate 13.

[0045] The bottom of the cooling water tank 12 is supported on a common base through a slide rail, and a gravity sensor for weighing the cooling water tank 12 is installed on the common base; a box pushing mechanism for pushing the cooling water tank 12 out or pulling it back along the slide rail is provided on one side of the cooling water tank 12.

[0046] The treatment method of the skid-mounted high-temperature plasma hazardous solid waste treatment device specifically includes the following steps: Step 1: pre-treat the collected hazardous solid waste, and continuously transport the hazardous solid waste in a slag-like state into a high-temperature plasma melting furnace 3 through a feeding device 2 .

[0047] Step 2: The hazardous solid waste in a slag-like state falls into the crucible 5 provided in the furnace, and the plasma torch 4 generates a large amount of heat energy, which continuously heats the hazardous solid waste in the crucible 5 to melt it. The temperature inside the furnace is 1000-1500°C, which can destroy most of the toxic and harmful substances in the hazardous solid waste, and the organic matter therein is rapidly gasified to generate a combustible synthesis gas mainly composed of H2 and CO. After the inorganic matter and the remaining toxic and harmful substances are melted, they are discharged into the cooling water tank 12 through the slag storage chamber 6 and cooled by circulating cooling water to form an inert and stable glass body.

[0048] Step 3: After the hazardous solid waste is thermally cracked in the high-temperature plasma melting furnace 3, the generated combustible synthesis gas is discharged through the melting furnace exhaust port on the upper side wall of the high-temperature plasma melting furnace 3. Under the suction action of the induced draft fan 10, the combustible synthesis gas first enters the rapid cooling and dust removal device 7 through the exhaust pipe for primary cooling and primary dust removal; then enters the condenser 8 for secondary cooling, and a shell and tube heat exchanger is used to further recover the sensible heat contained in the combustible synthesis gas.

[0049] Then the combustible synthesis gas enters the washing tower 9 for secondary dust removal. A spray pipe is provided on the top of the washing tower 9 to circulate and spray the synthesis gas to obtain a relatively pure combustible synthesis gas mainly composed of H2 and CO. The gas enters different processing devices through the rack synthesis gas outlet 11, or directly enters the combustion equipment as a gas fuel.

[0050] When the glass in the cooling water tank 12 reaches a certain weight, the gravity sensor sends a signal to the control system, and the control system controls the box pushing mechanism to push out, pushing the cooling water tank 12 away from the bottom of the high-temperature plasma melting furnace along the slide rail; then the telescopic rod 14 extends to lift the free end of the filter plate 13, so that the glass floats to the surface of the liquid. After the glass is cleared out, the telescopic rod 14 retracts to reset the filter plate 13; then the control system controls the box pushing mechanism to pull back, so that the cooling water tank 12 returns to the bottom of the high-temperature plasma melting furnace along the slide rail.

[0051] Compared with other methods, the skid-mounted high-temperature plasma treatment of hazardous solid waste of the present invention has the following advantages: This skid-mounted high-temperature plasma hazardous solid waste treatment device can almost completely convert carbon-based waste in hazardous solid waste into inert glass and combustible synthesis gas, which is more efficient than other technologies. Compared with traditional treatment technologies, this technical solution can completely decompose toxic and harmful substances such as nitrogen oxides and dioxins in hazardous solid waste. After the hazardous solid waste is melted, the toxic and harmful substances in the ash are sealed by the melted inorganic matter to form a harmless and stable inert glass.

[0052] The combustible synthesis gas and glass produced by this skid-mounted high-temperature plasma hazardous solid waste treatment device can be recycled, which greatly reduces the overall energy consumption of the system from the perspective of energy utilization.

[0053] In summary, the skid-mounted high-temperature plasma hazardous solid waste treatment device of the present invention solves the outstanding problems of traditional hazardous solid waste treatment methods such as waste of resources, large floor space, high cost, low efficiency and environmental pollution. The application of the skid-mounted high-temperature plasma hazardous solid waste treatment device fundamentally solves the source of pollution. The overall system can achieve all-weather operation. The plasma torch 4 can appropriately and reasonably adjust the power according to the information status of each subsystem under the treatment system collected by the control system analysis, thereby improving the efficiency of the system. The skid-mounted high-temperature plasma hazardous solid waste treatment device can operate at full load in harsh environments, and is more efficient, safe, reliable and pollution-free than other treatment methods.
