Plasma waste treatment system and method

Abstract

The invention discloses a plasma garbage treatment system and method, comprising: a superheated steam drier to dry garbage; a plasma gasification furnace pyrolyzing the dried garbage under the high temperature of a plasma torch to generate hydrogen, carbon monoxide and carbon dioxide Mixed gas; the high temperature heat exchanger performs heat exchange and cooling of the mixed gas; the oxygen heat exchanger uses the mixed gas after heat exchange and cooling to heat the combustion-supporting oxygen to output flue gas; the quench tower uses lye to cool the oxygen output from the oxygen heat exchanger The flue gas is cooled and deacidified; the first dust collector removes dust from the flue gas treated by the quenching tower; the induced draft fan transmits the flue gas after the first dust collector removes dust; the gas internal combustion engine uses the flue gas transmitted by the induced fan to drive the generator Generate electricity and output flue gas; the waste heat boiler cools the flue gas output by the gas-fired internal combustion engine; the second dust collector removes dust from the flue gas cooled by the waste heat boiler, and sends it to the chimney for emission. By adopting the invention, the waste heat utilization rate and thermal efficiency of waste treatment can be improved.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a plasma garbage treatment system and method. Background technique [0002] The phenomenon of "garbage siege" has entered the public eye. Many cities are facing the problem of piles of garbage. In the face of the ever-increasing amount of urban waste generated, landfill disposal alone is already stretched. Although ordinary incineration can solve the problem of land occupation, it is controversial because of pollution. Existing garbage disposal facilities are in overload operation for a long time. According to the current landfill volume and landfill speed, the existing landfill will be filled in the near future. [0003] The main content of plasma waste treatment technology is to use high-power plasma torch to treat hazardous and harmful waste. The central temperature of the plasma torch can reach tens of thousands of degrees Celsius. The temperature at the edge o...
