Pyrolysis and gasification garbage incinerator adopting oxygen enriched combustion technique

Abstract

The invention discloses a pyrolysis and gasification garbage incinerator adopting an oxygen enriched combustion technique. The pyrolysis and gasification garbage incinerator comprises an oxygen preparation unit, an oxygen injection unit and an incinerator main body unit, wherein the oxygen injection unit is connected with the oxygen preparation unit and the incinerator main body unit, the oxygen injection unit comprises a booster fan, a shutoff valve and two oxygen flow control devices, and each oxygen flow control device comprises a flow meter, a regulating valve, a stop valve, a mixer and an air supply fan; the shutoff valve is connected with the flow meters; the incinerator main body unit comprises an incinerator body and a smoke purification device, and the incinerator body comprises a first combustion chamber, a second combustion chamber and a partition. According to the pyrolysis and gasification garbage incinerator, the problems of low combustion temperature and combustion efficiency, substandard pollutant discharge and the like caused by low oxygen content of air or low garbage calorific value can be effectively solved.

Description

technical field [0001] The invention belongs to the field of incinerators, and more specifically relates to a pyrolysis gasification garbage incinerator adopting oxygen-enriched combustion technology. Background technique [0002] In recent years, with the rapid development of the economy and the gradual improvement of people's living standards, the problem of domestic waste in my country has become more and more serious. Many large and medium-sized cities are facing the dilemma of "garbage besieged". And there is also the problem of domestic waste disposal in tourist spots. At present, the two main garbage disposal methods in our country are landfill and incineration. The composting method has higher requirements on garbage components and organic matter content, so it is rarely used. The landfill method has a simple process and low investment cost, and has been widely used in my country. However, in recent years, as my country's land resources have become more and more scar...

Problems solved by technology

[0005] 1) When dealing with garbage with high water content, the actual operation is not ideal

my country's domestic waste has complex components, high water content, and low calorific value. The calorific value of combustible gas produced after garbage pyrolysis is low and unstable. It is difficult to maintain the temperature of the second combustion chamber at a relatively high temperature only by combusting combustible gas. In the process, a large amount of auxiliary fuel such as diesel oil is often required,
