Abstract

The invention relates to the field of carbonization furnaces, in particular to a heat exchange method of a carbonization furnace. The method comprises the following steps: (1) arranging a horizontal carbonization furnace body, a vertical carbonization furnace body and a regenerative furnace, wherein a combustion chamber is formed in the regenerative furnace, the regenerative furnace is separatelyprovided with burners, and the gas outlet of the regenerative furnace is connected with a waste heat exchange device; (2) operating the horizontal carbonization furnace body firstly, adopting wood gasgenerated by the horizontal carbonization furnace body to supply heat for heating of the horizontal carbonization furnace body, then introducing the remaining wood gas into the combustion chamber, and performing ignition burning; (3) heating the combustion chamber to 750-900 DEG C, operating the vertical carbonization furnace body, and inputting wood gas generated by the vertical carbonization furnace body into the combustion chamber; (4) performing burning on the wood gas which is generated by the vertical carbonization furnace body and input into the combustion chamber; and (5) introducinggas obtained after combustion is conducted in the regenerative furnace into the waste heat exchange device, and performing heat exchange. The technical problems of low efficiency of waste heat exchange and low productivity are solved when the wood gas in an existing carbonization furnace is used as boiler fuel.

Description

technical field [0001] The invention relates to the field of carbonization furnaces, in particular to a heat exchange method for a carbonization furnace. Background technique [0002] At present, there are mainly two types of carbonization furnaces, one is a vertical furnace, such as the Chinese patent application number: CN201610527691. .3 The disclosed horizontal continuous biochar carbonization equipment. The main advantages of the vertical furnace are large capacity and large output. The wood gas produced during its production contains water vapor, tar, wood vinegar and other by-products. When it is operated alone, it needs to condense the water vapor, tar, wood vinegar However, the separated wood gas still has relatively high humidity. In this way, the heat exchange efficiency is not high when burning and heating the boiler, and the exhaust gas after combustion has to undergo complicated exhaust gas treatment before it can be discharged. , and when burning, it is easy...
