Horizontal plasma garbage gasification reaction chamber and gasification technology thereof

Abstract

The invention relates to a horizontal plasma garbage gasification reaction chamber and a gasification technology thereof. The reaction chamber comprises an automatic loading apparatus, a primary gasification zone, a plasma reaction zone, an automatic ignition device, a furnace temperature monitoring system, a furnace level monitoring system, an inlet and outlet gas temperature monitoring system, an inlet and outlet gas pressure monitoring system and a flame monitoring system. The primary gasification zone is provided with a rasping moving grate, a chain type adjusting and self-levelling apparatus; and the plasma reaction zone is a fission structure comprising a second thining zone and a gas fining cell. The gasification technology comprises the following steps of: automatic loading; primary gasification; plasma second thining; and plasma gas refining. According to the invention, gas is generated from calorific value of the garbage; the generated gas and slag are further processed by aplasma torch to remove harmful substances therein and increase gas output, reduce waste residue discharge, lower one-time investment cost and operating cost of garbage gasification and purify the gas.

Description

technical field [0001] The invention relates to a technology for generating electricity by plasma gasification of domestic waste, in particular to a horizontal plasma waste gasification reaction chamber and a gasification process thereof. Background technique [0002] The main methods of domestic waste disposal in my country are landfill and incineration. Landfill not only occupies a large amount of land, but also pollutes groundwater, which is a last resort. Even so, there are not many sites available for landfills in areas with tight land resources. Although the incineration method has a high volume reduction ratio and can recover energy, it has been strongly opposed by the public due to pollution problems such as dioxins. It is urgent to develop a new generation of green, environmental protection, energy saving and consumption reduction alternative incineration technology. [0003] Plasma is the fourth state of matter and has many unique physical and chemical properties...

AI Technical Summary

Problems solved by technology

[0006] However, there are still many deficiencies in the current plasma garbage gasification technology. First of all, direct gasification of garbage with a plasma torch requires a huge power, and its power consumption rate can reach 30%-45% of its power generation capacity. Excessive electricity leads to greatly increased operating costs, making it unworthy of commercial operation

Second, this method gasifies garbage, and a dioxin treatment device needs to be added to th...
