Technical field
The utility model relates to a kind of flue gas flow guiding device, is specifically related to a kind of high-temperature flue gas guiding device, is applied to the metallurgical furnaces such as mineral hot furnace, carbon bar furnace, electrolytic furnace and does low-temperature flue gas waste heat recovery.
Background technology
At present the ferroalloy industry mineral hot furnace and electrode furnace etc. utilize fume afterheat power generation project, major part to be all to cause generated energy maybe can not generate electricity less because the flue-gas temperature of utilizing is too low according to investigations.So mineral hot furnace waste heat recovery flue gas has become a technical bottleneck in industry.Main cause is can not be entering the cold wind of stove and hot flue gas separately when flue exhausting, the amount that oven door opening cold air enters flue too much when smoke evacuation cold air more than hot-air, cause flue-gas temperature too low and do not generate electricity or generated energy minimizing.The 4th batch of the ferroalloy industry access list You700Duo company of National Development and Reform Committee according to incompletely statistics, mineral hot furnace has several thousand more than.If all make exhaust heat recovery power generation station, interests of bringing and energy-conservationly all can not despise.
Existing In The Sub-mergedfurnace of The Ferroalloys is done in exhaust heat recovery power generation project, and the flue-gas temperature of extraction, in 150 degree left and right, degree-200, does not reach the generating effect of expection.Its main cause is that a large amount of cold airs enters flue by fire door, and the flue-gas temperature of stove inside has been reduced, if fire door is shut, the carbon monoxide that does not have cold air to enter in stove raises again, has potential safety hazard; Secondly fire door shutoff operation workman also cannot be led to stove and reinforced operation.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of flue gas flow guiding device, simple in structure, easy to assembly, can effectively avoid cold air to sneak in flue gas, keeps the higher temperature of flue gas.
For addressing the above problem, the technical scheme that the utility model adopts is as follows:
A high-temperature flue gas guiding device, it comprises petticoat pipe, flue and the annular kuppe being comprised of several metal contiguous block unit, and petticoat pipe is arranged on mineral hot furnace top, and annular kuppe is positioned at petticoat pipe inside, and the lower end of flue is positioned at annular kuppe; In annular kuppe, every two adjacent metal contiguous block unit sides are pegged graft mutually, described annular kuppe both ends open, and the area of the lateral cross section of kuppe is increased toward top gradually from bottom.
The utility model can also be realized by following scheme:
Preferred embodiment a kind of as the utility model, described metal contiguous block unit comprises two identical contiguous blocks of structure and contiguous block; On described contiguous block side, along side short transverse, be provided with raised line, its opposite side is provided with the groove matching with described raised line, and two contiguous blocks are pegged graft by raised line and groove.
Preferred embodiment a kind of as the utility model, described metal contiguous block unit comprises the first contiguous block and the second contiguous block, wherein the first contiguous block dual-side is respectively equipped with groove along its short transverse, and the dual-side on the second contiguous block is respectively equipped with the raised line matching with described groove.
Preferred embodiment a kind of as the utility model, the acute angle between described annular kuppe outer wall and horizontal plane is 80 °-40 °.
Preferred embodiment a kind of as the utility model, the metal contiguous block unit of described annular kuppe is resistant to elevated temperatures corrosion resistant plate, and the thickness of corrosion resistant plate is 0.5-1cm.
Compared to existing technology, the beneficial effects of the utility model are: high-temperature flue gas guiding device of the present utility model arranges an annular kuppe, the cold air that makes to enter in stove flows to change, by original cold air, directly enter flue and change into by path, furnace high-temperature district and heat up, thereby the flue-gas temperature entering in flue is increased to 350-500 ℃; In the utility model, annular kuppe can be by the access hole of petticoat pipe, fritter is installed combination and is made to enter the cold air flow direction change in stove, neither affect operative employee's operation, do not affect cold wind and enter filling in stove yet, not only safe but also reliable, fundamentally solved the technical bottleneck problem of mineral hot furnace cogeneration, make to send out waste heat group of motors working stability and reduce fluctuation fluctuating, improve generating efficiency, extend unit service life, fully UTILIZATION OF VESIDUAL HEAT IN cuts the waste.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
