Description
Technical Field
The utility model relates to a useless processing apparatus of danger, especially an utilize melting gasification stove to handle useless device of danger.
Background
Hazardous waste refers to solid and liquid waste (including industrial and medical waste) having one or more hazardous characteristics (e.g., corrosive, toxic, flammable, reactive, and infectious) or likely to harm the environment or human body and which needs to be disposed of as a hazardous material.
At present, the treatment of dangerous waste generally adopts landfill and incineration modes. The landfill mode has the defects of large occupied area and easy generation of secondary pollution; the traditional incineration belongs to an oxidation process, so that the fly ash generated by combustion contains harmful substances such as dioxin, the treatment result is not ideal, and the like
The invention discloses a device for melting and gasifying electronic garbage, which is an invention patent application number 201510903405.0 disclosed by 2016, 03, 09 and date of the national intellectual property office of the people's republic of China, and is named as an electronic garbage melting and gasifying device, wherein the device comprises a melting and gasifying furnace, a closed uniform feeder, a primary hot air distribution pipe and a slag forehearth which are arranged mutually to form an electronic garbage melting and gasifying part; comprises a combustion oxidizer, an ignition chamber, a burner and a secondary hot air distribution pipe which are arranged mutually to form a flue gas oxidation part; comprises a hot air exchanger, a primary air blower and a secondary air blower which are arranged mutually to form a hot air manufacturing part; comprises a low-pressure waste heat boiler as a heat energy recovery part; comprises a bag-type dust collector, a draught fan, a desulfurizing tower, a denitrating tower and a chimney, which form a conventional flue gas purification part. The invention leads the electronic garbage to be melted and incinerated at the high temperature of 1300-1400 ℃, the smoke containing carbon and hydrogen compounds is oxidized and burnt at the high temperature of 1000-1100 ℃, thus leading the toxic and harmful substances such as dioxin and the like to be thoroughly decomposed and destroyed, leading the harmful heavy metals to be wrapped and dissolved by the vitreous body in the slag, leading the valuable metals to be directly precipitated and separated from the slag, leading the heat energy to be completely released and being recycled and converted into steam. The device is special for electronic waste, and needs to be improved and perfected when being used for hazardous waste treatment.
Disclosure of Invention
The utility model discloses technical scheme's purpose utilizes the characteristics of current melting gasifier, provides the dangerous wastes material of processing that can be economic, environmental protection, and the precious device that utilizes melting gasifier to handle the danger that makes it become useless.
For realizing the purpose of the utility model, the adopted technical scheme is that: the utility model provides an utilize melting gasifier to handle useless device of danger, includes melting gasifier, installs the cinder ladle at melting gasifier slag notch, sets up feeder on melting gasifier, the heat exchanger that links to each other with melting gasifier, its characterized in that above-mentioned heat exchanger links to each other with melting gasifier through flue gas recovery pipe, is provided with water inlet and delivery port on heat exchanger, is provided with dust collector at heat exchanger's gas vent, and the gas vent of dust collector links to each other with secondary combustion device.
The secondary combustion device is an internal combustion generator set or a steam turbine generator set.

Drawings
Fig. 1 is a schematic view of the device of the present invention.
Detailed Description
In figure 1, 1-slag ladle, 2-slag discharge port, 3-melting gasification furnace, 4-heat exchanger, 5-water inlet, 6-generator set, 7-dust removing device, 8-water outlet, 9-flue gas recovery pipe and 10-feeding device.
As shown in FIG. 1, the hazardous waste entering the melting gasification furnace is dried, and then the dried hazardous waste is sent into the melting gasification furnace by using a feeding device arranged on the melting gasification furnace, and the organic matter is rapidly decomposed under the high temperature of 1200-1500 ℃ in the furnace to generate H2And the mixed combustible gas of CO and inorganic matters are completely melted under the action of high temperature to form vitreous slag which is settled to the lower part in the furnace, and after the slag accumulated in the furnace reaches a certain depth, a slag discharge port is opened to discharge the slag in the furnace into a slag ladle. After the slag in the furnace is discharged, the upper slag discharging port is blocked by refractory mortar.
The generated high-temperature mixed combustible gas absorbs heat through the heat exchanger, enters the dust removal device to remove particles in the mixed combustible gas, and then enters the secondary combustion device for combustion and utilization. The dust removing device adopts a bag-type dust remover or a cyclone dust remover, and can also adopt the cyclone dust remover and the bag-type dust remover or other dust removing modes according to specific conditions.
The heat exchanger is provided with a water inlet and a water outlet, cold water enters the heat exchanger through the water inlet, and hot water is discharged from the water outlet for use after heat carried by the high-temperature mixed combustible gas is absorbed.
The secondary combustion device can be a waste heat boiler, and the heat obtained after the waste heat boiler burns the mixed combustible gas can be used for hazardous waste drying treatment or hot water supply or heating.
The secondary combustion device can be an internal combustion generator set or a steam turbine generator set, the internal combustion engine or the steam turbine is driven to rotate by combusting the mixed combustible gas, and then the generator is driven to generate electricity by the internal combustion engine or the steam turbine.
Discharging the slag in the furnace to a slag bag, and then performing water quenching granulation to prepare a high-quality building material.
