Description
Technical field
The present invention relates to kiln, specifically is a kind of energy-saving shaft furnace.
Background technology
Kiln is meant the equipment in order to calcining materials or burnt product that is built into refractory material; Existing kiln mainly can be divided into shaft furnace and tunnel cave; Because the restriction of self structure design, no matter be shaft furnace or tunnel cave, all exist energy consumption greatly, not energy-conservation shortcoming; With the tunnel cave is example, and 1 ton of mullite of every calcining be who knows, needs quota of expenditure coal 800kg, and the wasting of resources that brings has thus not only improved production cost, and environment has been caused pollution; Based on this, be necessary to invent the little and energy-conservation brand-new kiln of a kind of energy consumption.
Summary of the invention
The present invention provides a kind of energy-saving shaft furnace in order to solve the big and problem of energy saving not of existing kiln energy consumption.
The present invention adopts following technical scheme to realize: energy-saving shaft furnace comprises charging system, shaft furnace preheating zone, combustion system, shaft furnace clinkering zone, shaft furnace salband, discharge system and heat recovery system; Described heat recovery system comprises tail gas recycle and smoke evacuation system and hot blast recovery system; Wherein, the delivery outlet of charging system is communicated with the input port of shaft furnace preheating zone, the delivery outlet of shaft furnace preheating zone is communicated with the input port of shaft furnace clinkering zone, and the delivery outlet of shaft furnace clinkering zone is communicated with the input port of shaft furnace salband, and the delivery outlet of shaft furnace salband is communicated with the input port of discharge system; The input port of tail gas recycle and smoke evacuation system is communicated with top, shaft furnace preheating zone, and the input port of hot blast recovery system is communicated with shaft furnace salband top, and the delivery outlet of hot blast recovery system is communicated with bottom, shaft furnace preheating zone; The delivery outlet of combustion system is communicated with shaft furnace clinkering zone middle part; The delivery outlet of discharge system is equipped with dust pelletizing system; Specifically all being decided according to the actual requirements of shaft furnace preheating zone, shaft furnace clinkering zone, shaft furnace salband with material.
Workflow is as follows: one, material is transported to the shaft furnace preheating zone by charging system and carries out preheating; Two, after preheating is finished, start combustion system, material is transported to the shaft furnace clinkering zone and calcines; Three, after calcining finished, material was transported to the shaft furnace salband and cools off; Four, after the cooling, material is exported by discharge system, and dust pelletizing system is eliminated the dust of discharge system delivery outlet; In this process, the flue gas gathering that material produces in preheating and calcination process enters the shaft furnace preheating zone, finally recycles by tail gas recycle and smoke evacuation system; The hot gas that material produces in cooling procedure then is back to the shaft furnace preheating zone by the hot blast recovery system, thereby has reduced the energy consumption in the warm; Compare with existing kiln, energy-saving shaft furnace of the present invention has adopted brand-new heat loop structure, thereby it has the little and energy-conservation characteristics of energy consumption; Compare by a large amount of experiments and to experimental data and to show: the computing formula that the heat energy safety factor of energy-saving shaft furnace of the present invention can reach 21.8%(heat energy safety factor is: (heat total income-heat total expenditure)/heat total expenditure); Test shows, adopting 1 ton of needed standard coal of mullite of energy-saving shaft furnace calcining of the present invention is 493.8kg, compare with tunnel cave (calcine 1 ton of mullite who knows need quota of expenditure coal 800kg), the energy-conservation percentage of energy-saving shaft furnace of the present invention can reach 38.28%; Considering that flue gas that tail gas recycle and smoke evacuation system reclaim is capable of circulation is used for the workshop heating again, and the energy-conservation percentage reality of energy-saving shaft furnace of the present invention can be up to 43.88%.
The present invention efficiently solves the big and problem of energy saving not of existing kiln energy consumption, and not only energy consumption is little for it, and energy-conserving and environment-protective, is applicable to the calcining of all kinds of materials and the preparation of burnt product.
