Description

Technical Field

[0001] The invention relates to the technical field of incinerators, in particular to a low-power consumption plasma melting incinerator. Background Art

[0002] With the development of industrial technology and the improvement of people's living standards, various wastes are constantly generated. At present, when dealing with hazardous materials such as medical waste and electronic waste, they are simply buried or burned in incinerators. Since the direct burial of hazardous materials will pollute the soil and groundwater and take up a lot of space, during the incineration process of the incinerator, due to the temperature limitation, some toxic components and materials that cannot be incinerated by fire still exist, and the temperature is difficult to control, which will produce a large amount of toxic gases, such as dioxins, CO, etc., and those residues and fly ash after incineration still need to be landfilled. In order to overcome the shortcomings of the incinerator system, people try to use arc plasma torches to treat toxic wastes, because the temperature of the plasma torch is much higher than that of ordinary combustion devices, so that the hazardous wastes can be completely decomposed.

[0003] The existing plasma melting incinerator can perform ultra-high temperature incineration on waste with good incineration effect. However, the plasma torch generator is arranged on the top of the furnace body and the position is fixed, which cannot effectively and fully incinerate the objects. In addition, the existing plasma melting incinerator has a fixed volume. When there are fewer objects to be incinerated, the entire furnace body still needs to be heated and incinerated. Not only is the incineration effect unsatisfactory, but it also wastes plasma, thereby wasting energy and increasing the cost of use. In addition, the cooling effect of the exhaust gas after incineration is poor, which is easy to affect the later exhaust gas treatment. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a low-power plasma melting incinerator, which solves the problem that the plasma torch generator in the existing plasma melting incinerator is arranged on the top of the furnace body and has a fixed position, and cannot effectively and fully incinerate the objects. In addition, the existing plasma melting incinerator has a fixed volume. When there are fewer objects to be incinerated, the entire furnace body still needs to be heated and incinerated, which not only has an unsatisfactory incineration effect, but also wastes plasma, thereby wasting energy, increasing the cost of use, and has a poor cooling effect on the exhaust gas after incineration, which is easy to affect the subsequent exhaust gas treatment.

[0012] Preferably, the cooling mechanism includes a coil and a plurality of baffles, the coil is fixedly installed inside the exhaust pipe, the plurality of baffles are fixedly installed on the inner top and inner bottom of the exhaust pipe in sequence, and the baffles on both sides are staggered and extend into the interval of the coil, the outer surface of the exhaust pipe is respectively penetrated and fixedly connected with a liquid inlet pipe and a liquid outlet pipe, and the liquid inlet pipe and the liquid outlet pipe are respectively fixedly connected to the two ends of the coil.

The rotation of the screw drives the first gear to rotate, thereby driving the threaded sleeve to rotate through the second gear. The rotation of the threaded sleeve drives the adjustment rod to move horizontally through the thread, thereby driving the plasma torch to move synchronously when the adjustment heat insulation board moves. Since the gear ratio of the first gear to the second gear is 1:2, the plasma torch can always be in the middle position between the adjustment heat insulation board and the inner wall of the combustion chamber, so as to facilitate ignition and combustion. The exhaust gas generated enters the exhaust pipe, and is baffled and buffered under the action of the baffle, thereby reducing the flow rate, so that the exhaust gas stays in the exhaust pipe for a longer time, and then can fully contact the coil, allowing the coolant in the coil to cool down, thereby improving the cooling effect. After the combustion is completed, the baffle is pulled open by the pull plate, and the remaining waste residue will fall into the collection chamber and be discharged through the discharge port.
