Abstract
The invention discloses a flame path improvement method for a roasting furnace, and relates to the flame path improvement method of the roasting furnace during an aluminum electrolysis anode manufacture process. The method is characterized in that on the basis of the traditional roasting furnace type, the improvement process is realized by decreasing the width of a flame path wall to increase the width of a material box. The flame path improvement method for the roasting furnace is simple and easy to operate on the roasting furnace maintenance. According to the calculation of heat transmission and pressure loss as well as the design improvement to achieve the purpose of transition from a wide flame path and a narrow material box to a narrow flame path and a wide material box, the time and the cost of the major repair of a furnace body are reduced, resources are saved, and the expense of the major repair is decreased.
Description
Technical field
A kind of baking furnace flame path remodeling method relates to a kind of remodeling method of baking furnace flame path of aluminium electrolysis anode production process.
Background technology
Present domestic carbon element factory adopts the open roasting furnace type more, because the carbon anode size is different, hopper width and the degree of depth are not sought unity of standard when causing type of furnace design, will certainly cause the existing type of furnace and new customer requirement baked anode size not to mate, the development of restriction carbon element factory, as the narrow hopper of existing wide quirk can be satisfied again the requirement of heating curve and production technology simultaneously to the transition of narrow quirk wide material box body of heater by redesign, saved again newly-built roaster expense simultaneously.
Summary of the invention
Purpose of the present invention is exactly to reach by the transition of the narrow hopper of wide quirk to narrow quirk wide material box hopper by improve revising design in order to provide a kind of, reduces time and the expense of body of heater overhaul, namely economizes on resources and reduces the baking furnace flame path remodeling method of overhaul cost.
The objective of the invention is to be achieved through the following technical solutions.
A kind of baking furnace flame path remodeling method is characterized in that its transformation process is on the basis of original roasting type of furnace, reduces the width of flue wall, to increase the width of hopper.
The present invention is a kind of baking furnace flame path remodeling method, it is characterized in that the width of its transformation process flue wall changes 470mm into by intrinsic 530mm, and hopper becomes 770mm by original 710mm.
The present invention is a kind of baking furnace flame path remodeling method, and operation is simple, is easy to realize.By conducting heat, the calculating of the pressure loss, improving and revise design and reach by the transition of the narrow hopper of wide quirk to narrow quirk wide material box hopper, reduce time and the expense of body of heater overhaul, namely economize on resources and reduce overhaul cost.
The specific embodiment
Concrete implementer's case has as follows:
A kind of baking furnace flame path remodeling method, under original roaster basic framework, to the design of making amendment of hopper inside all refractory brick of flue wall, former flue wall wall thickness is 110mm, now revise the brick reduced width to 100mm, other special form bricks are 470mm by original 530mm length adjustment, and flue wall internal flame space becomes present 270mm by original 310mm, and hopper becomes 770mm by original 710mm.By experiment, this design can be satisfied the intensification requirement preferably, and has reduced energy consumption.
Embodiment
A kind of baking furnace flame path wall design size is long 5298mm, wide 530mm, high 5496mm, because flue wall distortion is serious, now again width is made as 470mm according to the actual requirements, with refractory brick by original 110mm, become 100mm, middle passage of flame becomes 270mm by 310mm, and the hopper width becomes 770mm by former 710mm simultaneously.The increase of hopper width can adapt to more kind, has increased batch, has reduced consumption and cost, has saved the energy.
Claims (2)
1. a baking furnace flame path remodeling method is characterized in that its transformation process is on the basis of original roasting type of furnace, reduces the width of flue wall, to increase the width of hopper.
2. a kind of baking furnace flame path remodeling method according to claim 1 is characterized in that the width of its transformation process flue wall changes 470mm into by intrinsic 530mm, and hopper becomes 770mm by original 710mm.
