Description
Technical field
The utility model relates to a kind of energy saver, particularly a kind of baking oven exhaust gas recirculation energy saver.
Background technology
In the drying materials process of industries such as coating, printing and dyeing, electronics and printing, the fresh air that being used for more than 90% of baking oven energy consumption will enter baking oven is heated to the process requirements temperature of baking oven, and this heat enters in the atmosphere along with high temperature (about 100 ℃-150 ℃) exhaust gas discharging simultaneously.Such as a total discharge amount of exhaust gas is 10, the baking oven of 000m3/h, the heat energy that the normal temperature air (25 ℃) that enters baking oven is heated to process requirements temperature (120 ℃) needs is 300,000Kcal/h, as providing the mode of heating of heat energy with diesel oil for fuel, annual diesel oil cost is about 1,600,000 yuan, as uses electrically heated mode of heating, annual power cost is about 2,000,000 yuan, and energy consumption cost is very high.For the more piece baking oven (three the joint or three the joint more than), first-half baking oven exhaust gas discharged concentration (generally being organic solvent gas concentration or water vapor concentration) is higher, and since the 3rd joint, exhaust gas concentration is general just very low, the closer to the baking oven of being dried material outlet, exhaust gas concentration is just low more.Present operating position is, no matter the height of exhaust gas concentration, each waste gas that saves baking oven all directly is discharged to atmosphere, does not take effective conservation measures.
The utility model content
The technical problems to be solved in the utility model provides a kind of energy-saving and cost-reducing baking oven exhaust gas recirculation energy saver.
For solving the problems of the technologies described above, the utility model baking oven exhaust gas recirculation energy saver comprises the baking oven that some joints are arranged in order, all be provided with fresh wind tube and blast pipe on each joint baking oven, it is characterized in that: described baking oven is divided into two groups in order, and the blast pipe of second group of baking oven is connected with the fresh wind tube of first group of baking oven.
Preferably, described baking oven comprises at least three joints, and first group comprises at least two joint baking ovens, and second group comprises at least one joint baking oven.
Preferably, be equipped with air exhauster on the blast pipe of described baking oven.
Preferably, the blast pipe of described second group of baking oven all is connected with an exhaust main, and the fresh wind tube of described first group of baking oven all is connected with a new wind house steward, and described second group exhaust main is connected with first group new wind house steward.
Further, also be connected with total new wind air door on the described first group new wind house steward.
After adopting such structure, the high temperature low concentration gas that will discharge near second group of baking oven of material outlet is introduced first group of baking oven as the new wind of air inlet, thereby improves the intake air temperature of first group of baking oven, realizes purpose of energy saving.The utility model can reduce the energy consumption of baking oven more than 30%.
Description of drawings
Fig. 1 is a front view of the present utility model.
Reference numeral is as follows:
1, baking oven 4, material inlet
2, fresh wind tube 5, material outlet
21, new wind house steward 6, total new wind air door or fresh wind port
3, blast pipe 7, atmosphere or relevant waste gas treatment equipment
31, exhaust main 8, air exhauster
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The utility model be will introduce the front near the high temperature low concentration gas of number joint baking oven 1 discharging of material outlet 5 a few joint baking ovens 1 as the new wind of air inlet, thereby improve the intake air temperature of a few joint baking ovens 1 in front, realize purpose of energy saving.The utility model can reduce the energy consumption of baking oven 1 more than 30%.
In order to realize above energy-conservation purpose, the technical scheme that the utility model is taked is: the utility model comprises the baking oven 1 that some joints are arranged in order, all be provided with fresh wind tube 2 and blast pipe 3 on each joint baking oven 1, baking oven 1 is divided into two groups in order, and the blast pipe 3 of second group of baking oven 1 is connected with the fresh wind tube 2 of first group of baking oven 1.First group of baking oven 1 is connected with material inlet 4, and second group of baking oven 1 is connected with material outlet 5.
The utility model comprises some joint baking ovens 1, first segment baking oven 1 is provided with material inlet 4, final section baking oven 1 is provided with material outlet 5, baking oven 1 one ends are connected with fresh wind tube 2, baking oven 1 other end is connected with blast pipe 3, and some baking ovens 1 of close material outlet 5 sides are connected by the fresh wind tube 2 of blast pipe 3 with the baking oven 1 of remainder.
As shown in Figure 1, be example with five joint baking ovens 1, the blast pipe 3 that baking ovens 1 are saved in back three is summarised in together, more total blast pipe 3 is linked to each other with the fresh wind tube 2 of first-half baking oven 1.
The low concentration high-temp waste gas of back three joint baking ovens 1 discharge has just entered first-half baking oven 1 as new wind like this, the new wind of the normal temperature that enters first-half baking oven 1 is significantly reduced, the high-temp waste gas that back three joint baking ovens 1 are discharged mixes with the new wind of normal temperature in first-half baking oven 1, improved the intake air temperature of the new wind of first-half, thereby saved the heating energy consumption of baking oven 1, reduced the production run cost.Simultaneously, because first-half baking oven 1 exhaust gas discharged concentration is higher, the utilization that can not reflux need directly be discharged to atmosphere or relevant waste gas treatment equipment 7.
Baking oven 1 joint number of actual drying materials process may be more than three joints, four joints or four save, all can be according to the exhaust gas constituents of reality and the parameter of materials of oven dry, the air draft of back number joint baking oven 1 is introduced preceding number joint baking oven 1 as new wind, such as to a cover three nodal pattern baking ovens 1, can save the new wind of the air draft of baking oven 1 with the 3rd as first-half baking oven 1; To a cover four nodal pattern baking ovens 1, third and fourth can be saved the new wind of baking oven 1 air draft as first-half baking oven 1; To a cover six nodal pattern baking ovens 1, can be with third and fourth, five, six joint baking ovens 1 air drafts are as the new wind of first-half baking oven 1, also can be with the new wind of fourth, fifth, six joint baking ovens, 1 air draft as first, second and third joint baking oven 1; For always having seven joints, eight joints or have more piece more to count the baking oven 1 of type, can the rest may be inferred.Because the air draft concentration of back number joint baking oven 1 is very low, can not influence by the quality of oven dry product.After adopting this kind reflow method, the heating energy consumption of baking oven 1 can reduce more than 30%.
In order to ensure preceding number joint baking oven 1 enough new wind is arranged, a total new wind air door need be installed as shown in Figure 1 on the new wind house steward of preceding number joint, or a fresh wind port only is installed also can, should be the door that often blows in by total new wind air door, when new wind total amount that the air draft total amount of back number joint baking oven 1 needs less than preceding number joint baking oven 1, the new wind of normal temperature will enter from total new wind air door 6 automatically, to guarantee to enter the process requirements that the preceding resh air requirement of counting joint baking oven 1 can satisfy oven dry.
Above-mentioned design example only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substantial equivalence means that it may occur to persons skilled in the art that are all in the utility model claim scope.
