Description
Technical field
The utility model relates to a kind of reclaimer, be specifically related to a kind of baking oven waste heat recovery apparatus.
Background technology
Chinese's fabricate-leather, synthetic leather industry are through development decades, world's artificial leather, synthetic leather big producing country are become, thousands of families of current national joint owner's fabricate-leather synthetic leather enterprise, more than 2000 production line, be the industry that plastic cement industry is given priority to, scale wherein has more than 800 of dry process production line above, more than 400, wet method line, article 200, left and right calendaring line, also has 30 superfine fibre production lines (built and building) and some coatings, flocking and only has the manufacturer of calendaring line.The interior required hot blast temperature of general PU dry-process production line baking oven is about 120 ℃-130 ℃, and (in PU wet method line baking oven, required hot blast temperature is about 170 ℃ of-180 ℃ of left and right, in PVC dry-process production line baking oven, required hot blast temperature is about 200 ℃-220 ℃, in base cloth forming machine baking oven, required hot blast temperature is about 180 ℃-200 ℃), it is general consistent with oven temperature that tail gas leaves the EGT of baking oven, and waste heats are taken out of outside baking oven in a large number.If add fuel combustion loss and body radiation loss etc., have more than 90% and spill into atmosphere by exhaust through the heat of estimation input baking oven, the heat really consuming for the treatment of fabric has only accounted for 2.9% of input baking oven heat.Dispersed heat not only wastes energy but also causes the rising of artificial leather baking oven workshop condition temperature and affect operator's physical and mental health, is therefore imperative to the waste heat recovery of baking oven.
Summary of the invention
For the deficiency existing in prior art, the utility model object is to be to provide a kind of baking oven waste heat recovery apparatus, has thoroughly eliminated several primary conditions of substance combustion, has also just thoroughly solved the disaster hidden-trouble of artificial leather baking oven production process.
To achieve these goals, the utility model is to realize by the following technical solutions: baking oven waste heat recovery apparatus, comprise casing, tail gas import screen pack, central dividing plate, Copper & Aluminum Fin and fresh inlet screen pack, casing middle part is provided with central dividing plate, on central dividing plate, be equipped with many Copper & Aluminum Fins, right side, central dividing plate one end is provided with fresh inlet screen pack, and central dividing plate other end left side is provided with tail gas import screen pack.
Described Copper & Aluminum Fin 4 adopts equilateral triangle arrangement by certain ranks spacing.
The utlity model has following beneficial effect:
1. utilize the outer row's of baking oven tail gas heat quantity, fresh air outside is heated to after uniform temperature in supplier's fabricate-leather baking oven (tail gas exhaust temperature and the EAT temperature difference are in 50 ℃).
2. the input of high temperature air, can save the energy of 20-30%, and production efficiency can increase 6-8%.Simultaneously high temperature air enter the decline that has prevented from drying the temperature inside the box.
3. the minimizing of baking oven internal cause cool exterior air injection rate, has reduced the generation of hydrometeor, reduces the aberration therefore causing simultaneously.
4. by the elimination of pollutant and the reduction of EGT, improve later purification effect, dried on separate unit fan outlet because this equipment is directly loaded on artificial leather, eliminated the problem that oil stain and fibre dust are accumulated in follow-up air channel.Waste gas is just discharged and is just purified and lowers the temperature from blower fan, makes waste gas not reach the detonation required temperature of catching fire at all.Therefore thoroughly eliminate several primary conditions of substance combustion, also just thoroughly solved the disaster hidden-trouble of artificial leather baking oven production process.
Accompanying drawing explanation
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
With reference to Fig. 1, this specific embodiment is by the following technical solutions: baking oven waste heat recovery apparatus, comprise casing 1, tail gas import screen pack 2, central dividing plate 3, Copper & Aluminum Fin 4 and fresh inlet screen pack 5, casing 1 middle part is provided with central dividing plate 3, on central dividing plate 3, be equipped with many Copper & Aluminum Fins 4, central dividing plate 3 right sides, one end are provided with fresh inlet screen pack 5, and central dividing plate 3 other end left sides are provided with tail gas import screen pack 2.
It should be noted that described Copper & Aluminum Fin 4 heat-pipe elements adopt equilateral triangle arrangement by certain ranks spacing.
Heat pipe is a kind of novel heat transfer element with hot high thermal conductivity, its capacity of heat transmission exceedes any known metal, heat pipe is by having increased heat exchange area around upper fine aluminium fin on sealed at both ends copper pipe, injects best liquid refrigerant and form after cleaning and being pumped into high vacuum.Heat pipe utilizes the physical process of the phase transformation of working medium to carry out transferring heat, heat pipe one end is evaporator section, the other end is condensation segment, in the time that heat imports into from evaporator section, working medium in liquid-sucking core is subject to thermal evaporation, become steam, steam flows to condensation segment under small pressure differential, touch cold heat exchanger core surface at condensation segment, releases heat, regelation becomes liquid, condensate liquid borrows the effect of capillary force and gravity to be back to evaporator section, complete closed circulation, so circulation is more than, evaporation and condensation by working medium are not just passed to cold junction from hot junction to section in a steady stream heat, this circulation is carried out fast, therefore heat pipe has very high thermal conductivity.Because an adopting heat pipes for heat transfer amount is limited, so heat-pipe elements is adopted to equilateral triangle arrangement by certain ranks spacing, bunchy is contained in the housing of framework, has angle slightly when installation, so that the condensing reflux of working medium.With central dividing plate by the bringing-up section of heat pipe and radiating segment separately, form heat exchange of heat pipe.The outer row's of baking oven high-temperature tail gas, due to heat pipe heat absorption, is delivered to heat pipe by heat rapidly, and negative pressure in baking oven needs to supplement fresh air, and fresh air heats rapidly through superheater tube, enters in artificial leather baking oven.Air-flow circulates always, and supplementing of high temperature air makes baking oven remain on the condition of high temperature always, reaches energy-conservation object.Screen pack has been installed respectively in import at cold and hot air.Need periodic cleaning.To guarantee the smoothness of hot and cold air.
This specific embodiment has thoroughly been eliminated several primary conditions of substance combustion, has also just thoroughly solved the disaster hidden-trouble of artificial leather baking oven production process.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
