Problems solved by technology

However, all waste incineration power plants only use the heat energy generated by waste incineration, and the discharge or resource utilization of secondary pollutants in the process of waste incineration has not yet been resolved.
[0004] Existing waste incinerators use auxiliary fuel—diesel or coal, plus air for combustion. The combustion temperature in the furnace is only 800-1000°C. It is difficult to completely burn the garbage organic matter in the furnace, because the combustion temperature in the furnace is lower than 1200°C. When the organic matter in the garbage is not completely burned, it is easy t

Embodiment Construction

[0013] The present invention is described in further detail by the following examples.

[0014] see figure 1 As shown, the device for producing carbon dioxide by high-temperature incineration of garbage consists of a flue gas waste heat drying chamber 3, an incinerator 4, a steam generator set 6, an air separation device 1, a biochemical treatment pool 2, an ash recovery chamber 5, a flue gas desulfurization chamber 7, Clean room 8, liquefier 9 components. The garbage is compressed and packaged and transported to the garbage incineration plant, stored in the biochemical treatment pool 2, and undergoes biochemical treatment after a turnaround period of 3-7 days. The biochemically treated garbage is sent to the flue gas waste heat drying chamber 3, and dried Send in the incinerator 4 again again, utilize the methane produced by the biochemical treatment tank 2 to pass into the rubbish after igniting the drying in the incinerator 4, meanwhile, the pure oxygen produced by the air...

Abstract

The invention discloses a device adopting the high-temperature burning of the garbage to produce the carbon dioxide. With the device, the temperature inside the burning furnace can exceed 1200 DEG C, and the content of the dioxin in the smoke generated in the furnace is greatly reduced, but the concentration of the CO2 gas is greatly increased, so that the CO2 gas in the smoke has the industrialized recycling value. On the basis of the original garbage burning electricity generation device, the device is additionally provided with an air separation device and a biochemical processing pool; the methane that is generated in the biochemical processing pool is introduced to fire the garbage that is dried in the burning furnace; the pure oxygen that is generated by the air separation device is directly introduced into the burning furnace to assist the combustion of the garbage for adequate combustion; the smoke is desulfurized and purified to get the CO2 gas after the purification; the gaseous CO2 is converted into the liquid CO2 through a liquefied furnace.

Description

technical field [0001] The invention relates to the technical field of carbon dioxide production, in particular to a device for producing carbon dioxide by high-temperature incineration of garbage. Background technique [0002] Garbage includes domestic waste and industrial waste. Domestic waste includes domestic waste from urban residents, domestic waste from urban street cleaning, domestic waste from urban catering industries, sludge from urban domestic wastewater treatment plants, and urban river stream cleaning. sludge, feces of urban residents, waste tires, etc. The "three modernizations" treatment of waste refers to reduction, harmlessness, and waste recycling. Apply incineration technology to send waste garbage into the incinerator, and convert the organic carbon in the garbage into CO through incineration oxidation reaction 2 , the conversion of hydrogen to H 2 O, turning waste into valuable products, and killing viruses and bacteria at high temperatures, to achie...
