Ignition combustion assisting device for garbage thermal cracking furnace

Abstract

The invention discloses an ignition combustion assisting device for a garbage thermal cracking furnace. The ignition combustion assisting device is arranged at the bottom of the thermal cracking furnace, and comprises an extension device at the bottom and a pull rod arranged at the front end of the extension device; the front end of the pull rod is connected with an ejector rod; the ejector rod is hollowed, and is provided with a cap at the top end; a plurality of fire spraying holes are formed in the side wall of the upper part of the ejector rod; an ignition device and an oil pipe are arranged in the hollow of the ejector rod; and the oil pipe is connected with an external oil supply system. The invention aims to provide the ignition combustion assisting device for the garbage thermal cracking furnace, prevents garbage in a combustion furnace from caking, accelerates full garbage combustion, reduces the tail gas emission, 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 an ignition and combustion-supporting device for a garbage pyrolysis 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 leachate, which will increase technical diff...

AI Technical Summary

Problems solved by technology

[0004] For large garbage incinerators, the volume of the incinerator is relatively large, so it is necessary to continuously input fuel (garbage) to maintain its continuous combustion; and the incinerator is fed in sections, one by one from each feeding port; however, the combustion of garbage is not consistent , the garbage put in later will cover the garbage in the front, and the garbage in the front is easy to agglomerate because it is not fully burned, and the agglomerated garbage gathers together to block the combustion of combustibles in the block, making the garbage incompletely burned; In addition, it is easy to produce a large amount of harmful gas, which will bring trouble to the exhaust gas treatment in the later stage.
