に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a hot air circulation baking furnace used for manufacturing wire rods, strips, tubes, etc. (hereinafter referred to as wire rods) having enamel coatings or other synthetic resin coatings.

ようにしている。 As is known, a wire having an enamel coating or the like is passed through a furnace and subjected to a baking treatment to harden the coating. At this time, the coating before the baking process contains a highly volatile and combustible solvent, and the concentration of the vaporized solvent increases in the furnace, causing an explosion.
This will deteriorate the quality of the wire coating, etc. Therefore, a part of the hot air in the furnace is exchanged with fresh air, and harmful components contained in the exhaust gas discharged to the outside are treated by exchanging the hot air.

化学処理あるいは燃焼処理により規準値以下に処
理していた。 More specifically, in this type of conventional baking furnace, an electric heater placed in the wire passageway in the furnace heats the wire passing through the inside of the furnace, and at this time, an appropriate amount of air is injected into the wire passageway from the air inlet. At the same time, a portion of the hot air in the wire passage is discharged to the outside from the exhaust port, and when exhausting, harmful components in the hot air are reduced to standard values through chemical treatment using a catalyst or combustion treatment. It was processed as below.

な温度分布を得るにも困難を伴なつていた。 Even in the conventional example described above, the concentration of vaporized solvent in the furnace is reduced by introducing fresh air, and the exhaust gas is treated, so the above-mentioned explosion accident can be avoided.
Problems such as pollution will be solved for the time being. However, in the case of this conventional example, since fresh air (low temperature) is constantly introduced, a considerable amount of thermal energy is consumed to maintain the desired temperature in the furnace, which is uneconomical. On the railway,
Temperature variations were large between the area where fresh air was introduced and other areas, making it difficult to obtain the optimum temperature distribution for baking the wire.

It was hot.

るものである。 In view of the above-mentioned problems, the present invention reduces the concentration of vaporized solvent, eliminates thermal energy loss, and makes it possible to control the temperature inside the furnace by circulating the hot air inside the baking furnace while purifying it. In addition, when a part of the circulating hot air is released to the outside after the purification process, the hot air is purified again to further prevent pollution and reduce overall thermal energy consumption. The aim is to increase efficiency.

したがつて本発明焼付炉の場合、省エネルギ、
公害防止、炉内温度制御性等について、つぎのよ
うな効果が得られる。 Therefore, in the case of the baking furnace of the present invention, energy saving,
The following effects can be obtained in terms of pollution prevention, furnace temperature control, etc.
(1) 所定の経路で熱風を循環させた際、循環熱風
が常時酸化触媒処理器により浄化処理されるの
で、線材通路内における線材被膜からの気化溶
剤濃度を抑えることができる。(1) When hot air is circulated through a predetermined route, the circulating hot air is constantly purified by the oxidation catalyst treatment device, so the concentration of vaporized solvent from the wire coating in the wire passage can be suppressed.
かくて、線材通路内の気化溶剤濃度が抑えら

出熱量も少なくなり、熱風有効量を高めてエネ
ルギロスの低下をはかり得る。 In this way, by suppressing the concentration of vaporized solvent in the wire passage, frequent or large amounts of hot air exchange is not required, and therefore, the hot air temperature distribution in the wire passage, once maintained at a predetermined temperature, is not disturbed by hot air exchange. The amount of heat released to the outside of the furnace is also reduced, which increases the effective amount of hot air and reduces energy loss.
(2) 線材通路内の気化溶剤濃度が高まつた際、熱
風の一部が排風路より外部へ放出されるが、そ
の排風路に至る熱風はその手前の酸化触媒処理
器を介してすでに一次処理されており、しかも
当該排風路の排風処理器により再度二次処理を
受けるから、外部へ放出される熱風の有害性が
殆どなくなり、公害対策上の信頼性が高まる。(2) When the concentration of vaporized solvent in the wire passage increases, a portion of the hot air is discharged to the outside from the exhaust duct, but the hot air that reaches the exhaust duct passes through the oxidation catalyst treatment device before it. Since the hot air has already been subjected to primary treatment and is further subjected to secondary treatment again by the exhaust air treatment device in the exhaust air passage, the harmfulness of the hot air discharged to the outside is almost eliminated, increasing reliability in terms of pollution control.
(3) 排風路から放出する熱風量が、前述したごと
く少量であるので、ここに設けられた排風処理
器の能力も小さくて足り、排風処理器を用いる
際の生エネルギがはかれる。(3) Since the amount of hot air discharged from the exhaust air passage is small as described above, the capacity of the exhaust air treatment device provided here is also small enough, and the raw energy when using the exhaust air treatment device can be measured.
(4) 酸化触媒処理器の場合、その処理温度を得る
ための加熱器が必要となるが、ここで用いられ
る加熱器は炉内熱風の温度保持に兼用できる。(4) In the case of an oxidation catalyst treatment device, a heater is required to obtain the treatment temperature, but the heater used here can also be used to maintain the temperature of the hot air in the furnace.
(5) 線材通路における線材入口部、線材出口部の
近傍に、それぞれ開閉弁を有する空気導入口が
