Magnetization cracking device

Abstract

The invention relates to a magnetization cracking device for treating organic waste, which comprises a device body, a feeder, a grate bar, a magnetized air generator, a blowing fan, an ash discharger, a secondary combustor, a draining valve and an anti-explosion valve, wherein an exhauster comprises an alkaline water washing tank, an oxygen-deficient combustion chamber, a complete-oxygen combustion zone and a high-temperature catalytic chamber. The magnetization cracking device has the characteristics of environment friendliness, high efficiency and high safety; and after the organic waste is treated by magnetization cracking reaction and secondary combustion, the dioxin content in the discharged exhaust is nearly zero.

Description

technical field [0001] The invention relates to a magnetization cracking device for processing organic waste, in particular to a low-temperature magnetization cracking device for processing plastic products, rubber products, organic chemical waste and other organic substances. Background technique [0002] The traditional methods of waste disposal include landfill and incineration. The two treatment methods for medical waste, waste tires and other plastic products, rubber products and other organic matters will cause certain secondary pollution, especially in the process of incineration of organic matters such as HCI, SO x , NO x Such acid gases, highly toxic chlorine-containing polymer compounds (collectively referred to as dioxins), and dust, etc., cause serious air pollution. In order to overcome the shortcomings of waste incineration technology, waste pyrolysis technology has been developed. [0003] Inject a certain amount of strong magnetized air into the airtight de...

AI Technical Summary

Problems solved by technology

But this device still has certain problems technically: the device feeds from the top of the furnace body, and when the feeding door is opened during work, a large amount of smoke and dust will emerge from the feeding port, polluting the environment; the magnetic gas enters from the bottom of the furnace body, and the accumulated When there are many objects to be treated, there is less magnetic gas that can be exposed to the inside and the upper part, and the pyrolysis efficiency is difficult to guarantee; pyrolysis is carried out at about 600°C, and a large amount of dioxins will still be produced, and the waste gas will be discharged directly, resulting in dioxins It directly enters the atmosphere and pollutes the environment; the deodorization cylinder is used to absorb fly ash, and the deodorization cylinder needs to be replaced frequently, which increases the workload; When the slag discharge door is opened, the ash and slag will be blown out directly by the air flow due to the action of the fan. If the slag discharge can only be stopped, the work efficiency cannot be guaranteed; a water vapor production device is installed, and the water vapor will condense and sink in the furnace. Bottom of the furnace, this part of water cannot be discharged, and the furnace body will be corroded after being mixed with acid gas

But this device can only be used to deal with domestic garbage; the ventilation pipe is arranged in the center of the furnace body to limit the volume of the object to be treated in the furnace body, and for large pieces of garbage, it can only be crushed and put in, which increases the working links; reaction It is carried out in the range of 250°C to 450°C. Dioxin will still be generated when burning organic matter in this temperature range. The device does not process it but directly discharges it, polluting the environment; the hollow furnace wall and air duct are easily produced by the reaction clogged with ashes
