Description
A kind of cupola furnace belongs to the auxiliary equipment technical field of hotblast stove with horizontal heat-exchange dedusting device, is mainly used in the cupola furnace burner gas residual heat and recycles and purifying exhaust air.
The interchanger of Hot Blast Longevous Cupola generally adopts Ceramic Balls interchanger or special-shaped tubular heat exchanger in the prior art.The former heat exchange efficiency is higher, but is not suitable for China's national situation, and it is broken serious that bonding phenomenon and wearing and tearing at high temperature often appear in Ceramic Balls, need often to replenish, thereby need special recovery and the sending spparatus that is equipped with a cover Ceramic Balls, and general technical requires high, and cost is also just high; And latter's complex structure, owing to adopt vertical installation, vertically thermal expansion problem is difficult to solve, special-shaped heat exchange tube machining technique complexity is difficult to make simultaneously, changes also extremely inconvenient.Moreover, the used cupola furnace of present domestic melting cast iron is gone into the stove wind-warm syndrome generally all below 250 ℃, belong to the cold wind category, generally contain the carbon monoxide about 17% in the waste gas of discharging during melting, contained potential and heat in this part waste gas, as not recycling direct discharging, not only can cause very big energy dissipation, but also can cause environmental pollution; Owing to general 400-500 ℃ of this part waste gas,, then must earlier the temperature of waste gas be reduced to below 120 ℃ again if use the sack cleaner dedusting, add the reinforced fluctuation that the fusing later stage all can cause spent air temperture that reaches, so the use bag-type dusting, not only the waste gas cooling requires height, and very dangerous.Also have the heat exchange of a kind of kiln formula in addition, the subject matter that it exists is that a thermal expansion difficult problem can't solve, and the burning of waste gas is wayward, and it is loosening easily to build the used refractory brick of kiln, hot blast kiln poor sealing performance, and structure is huge, and floor space is big.
The purpose of this utility model is to provide a kind of can solve existing various difficult problems in the prior art, structure is comparatively simple, design science is reasonable, integrate heat exchange and dedusting, dismounting is easy to maintenance, it is easy and indeformable to make, and can change heat transfer tube fast, and the cupola furnace that waste gas is evenly distributed in interchanger is with horizontal heat-exchange dedusting device.
Materialization characteristics according to heat exchange and waste-gas cleaning ultimate principle and cupola furnace waste gas, at existing questions in the prior art, basic design of the present utility model is: thoroughly reform on the basis that has vertical special-shaped tube heat exchanger and bag-type dusting heat-exchange dedusting device linked together now, promptly to change original baroque vertical special-shaped tube heat exchanger be simple in structure and level that easy making is housed in it is returned the horizontal heat exchanger of bent heat transfer tube, and change original need lower the temperature significantly and use the bag-type dusting that is absolutely unsafe for itself can be high temperature resistant to lowering the temperature less demanding early stage and can temperature with high efficiency dedusting high-efficiency ceramic multi-tube dust cleaner safe in utilization, thereby realize purpose of design.
Cupola furnace described in the utility model is with horizontal heat-exchange dedusting device, from the cupola furnace to the chimney, constitute by the pipeline 1 that is connected with cupola furnace, combustion chamber 2, interchanger 3, main air blower 4, cooling and dedusting device 5, induced draft fan 7 and chimney 8 successively and each member between be connected by pipeline, it is characterized in that this installs its above-mentioned interchanger 3 for horizontal and also by pipeline high-efficiency ceramic multi-tube dust cleaner 6 is housed between above-mentioned cooling and dedusting device 5 and induced draft fan 7.The waste gas that cupola furnace produces enters by pipeline 1 that carbon monoxide in 2 waste gas of combustion chamber is lighted and enters interchanger with adding the auxiliary fuel back of burning together with about 800 ℃ high temperature, enters in the atmosphere after the two-stage dedusting through heat exchange and preliminary waste gas cooled again.
Above-mentioned horizontal heat exchanger 3 is built to have high-temperature-resistant layer 22 levels to be placed on the supporting leg 17 and be the hollow cylinder bodily form that is slidingly matched and the cylindrical shell 13 which is provided with hand-hole 14 and be loaded on level in its cavity with circular trustship gripper shoe 24 supports with this supporting leg by its inwall and is returned bent heat exchanger tube 23 and be loaded on cylindrical shell 3 tops and the exhaust piping 9 that is connected with above-mentioned combustion chamber 2 consists of by waste gas inlet port 11 and flange 12, and this cylindrical shell 13 also cold air duct 15 by passing the end socket 16 that is connected with its flange is connected with above-mentioned main air blower 4 and by being connected with above-mentioned cooling dust remover 5 with the exhaust emission pipe 18 of dust hopper 19.
Too high in order to prevent heat exchange temperature, also can install the by-pass line 21 that has variable valve 20 on it again additional between above-mentioned exhaust pipeline 9 and the above-mentioned exhaust emission pipe 18.
The utility model has the advantages that: owing to take horizontal heat exchanger and which is provided with the hand-hole that all can uncap at any time and observe, so be convenient to maintenance, cylindrical shell adopts the hollow cylinder bodily form and two ends that dismountable sphere shape end socket is housed, not only easy processing and fabricating, indeformable, but also its interior heat transfer tube of fast changeable, cylindrical shell is placed on the supporting leg and is slidingly matched with circular arc all or part of being of supporting leg upper end, not only solved the thermal expansion problem of vertical direction, also solved simultaneously the horizontal direction thermal expansion problem, other is provided with a plurality of waste gas and imports and exports, make waste gas in interchanger, be evenly distributed, adopt the high-efficiency ceramic multi-tube dust cleaner, can not only be high temperature resistant, to lowering the temperature less demanding early stage, and very safe, the dedusting function that connects interchanger counts waste gas and just discharges behind 3-stage dust-removal, can recycle so use this to install not only burner gas residual heat, and exhaust also can be up to standard, can also reduce investment outlay.
