A high-efficiency cracking-promoting secondary combustion chamber waste pyrolysis heat energy conversion furnace

Abstract

The invention discloses a two-combustion-chamber garbage thermal cracking heat energy conversion furnace for efficiently accelerating cracking. The furnace comprises a furnace body; a main combustion chamber is formed in the furnace body; a feed port and a furnace cover plate are arranged above the furnace body; the periphery of an inner cavity of the furnace body is a hollow interlayer structure; the interlayer is divided into two layers separated up and down; a condensation cavity for cooling water vapor in the furnace is formed above the interlayer; a secondary combustion chamber communicated with the main combustion chamber is formed below the interlayer; a gas-liquid separation system communicated with the bottom of the condensation cavity is arranged on the outer side of the condensation cavity; an afterheat power generation system is arranged at the bottom of the furnace body; air blowing systems are connected to the side surface and the bottom of the furnace body; and a smoke discharge port is formed in the right side of the furnace body. The two-combustion-chamber garbage thermal cracking heat energy conversion furnace for efficiently accelerating cracking optimizes an air blowing oxygen supply pipeline, accelerates full garbage combustion, reduces the emission of tail gas, fully uses afterheat in a thermal cracking furnace, and improves the thermal combustion efficiency of the thermal cracking furnace.

Description

technical field [0001] The invention belongs to the field of garbage treatment, in particular to a high-efficiency cracking-promoting secondary combustion chamber garbage pyrolysis heat energy conversion furnace. Background technique [0002] With the continuous development of the economy and the acceleration of urbanization, the amount of municipal solid waste generated every year has doubled. The traditional way of garbage disposal is to build a landfill to landfill the garbage. There are many disadvantages in this method. The first is that it takes up a lot of land to build landfills. Land is a non-renewable resource, and land resources are already quite tight. Second, after a large amount of organic matter and batteries enter the landfill, the resulting The toxic leachate will cause serious pollution to soil and groundwater. From the perspective of environmental protection, it is necessary to establish an anti-seepage, collection and treatment system for landfill leacha...

Problems solved by technology

[0003] When the existing combustion furnace is thermally cracking garbage, the combustion is insufficient, and it is easy to generate large smoke pollution, which brings difficulties to the subsequent treatment; moreover, the thermal conversion efficiency of the thermal cracking furnace is low, and waste heat is much wasted, resulting in large pollution and waste
