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 the plasma gasification power generation technology of domestic garbage, in particular to a horizontal plasma garbage gasification reaction chamber and a gasification process thereof. Background technique [0002] The domestic waste disposal methods in my country are mainly landfill and incineration. Landfill not only occupies a large amount of land, but also pollutes groundwater, which is a last resort. Nevertheless, there are not many sites available for landfill in areas where land resources are scarce. 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. There is an urgent need to develop a new generation of alternative incineration technologies that are environmentally friendly and energy-saving. [0003] Plasma is the fourth state of matter, which has many unique physical and chemical properties di...

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 the subsequent gas purification process, which increases the initial one-time investment and greatly increases the equipment cost

Third, using a plasma torch to directly gasify garbage, due to the uneven distribution of its temperature field, the garbage cannot be completely treated at high temperature, and there will be a large amount of dioxins and other harmful substances in the discharged waste residue, which makes the treatment of its waste residue become a problem. a problem
