Abstract

The utility model relates to a production facility for enamelled wires, particularly to a preheating device for the catalytic combustion of an oven of a wire enamelling machine. The utility model comprises a preheating chamber for catalytic combustion, catalytic combustion chambers 1 and 2, an inlet pipe for hot air current and an outlet pipe for the hot air current, wherein the inlet pipe is connected with the catalytic combustion chamber 1, and the outlet pipe is connected with the catalytic combustion chamber 2. The utility model has the purpose of making use of the hot air current which is generated after self catalytic combustion to heat vaporized gas before the catalytic combustion so as to realize the purposes of energy saving and catalyst poisoning prevention.

Description

Enamel-covered wire machine baker catalytic combustion preheating device

Technical field

The utility model relates to a kind of enamel-covered wire machine baker catalytic combustion preheating device

Background technology

In the present enamel-covered wire industry, the solvent boil-off gas that produces in the Production of Enamel Wires process, the used preheating temperature of catalytic combustion all need lean on electricity heating, and power consumption is big, and catalyst is easily poisoned.

Summary of the invention

In order to reach energy-conservation and to prevent owing to the preheating untimely purpose that makes catalyst poisoning of heating, the utility model adopts following technical scheme, a kind of enamel-covered wire machine baker catalytic combustion preheating device, comprise catalytic combustion Room 1, Room 2, thermal current inlet tube and thermal current outlet, the thermal current inlet tube is connected with catalytic combustion Room 1, and outlet is connected with catalytic combustion Room 2.In Production of Enamel Wires, the white spirit boil-off gas, the thermal current that behind catalytic combustion, produces, part turns back to the catalysis boil-off gas that comes to heat, and makes it to reach the required temperature of catalytic combustion.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model

1. catalytic combustions Room 2 among the figure, 2.

catalytic combustion Room

1,3. control valve, 4. thermal current inlet tube, 5. economizer bank, 6. thermal current outlet, 7. catalysis preheating chamber, 8. catalyst.

The specific embodiment

Between catalytic combustion Room 2 (1), the catalytic combustion Room 1 (2) control valve (3) is arranged in the drawings, thermal current inlet tube (4) upper end is connected with catalytic combustion Room 1 (2), the lower end is connected with economizer bank (5), thermal current outlet (6) upper end links to each other with catalytic combustion Room 2 (1), and the lower end is connected with economizer bank (5) other end.Enamel-covered wire solvent vaporized gas enters the catalysis preheating chamber, heats to (400 ℃～450 ℃) through economizer bank (5), reaches to make catalyst (8) play the active catalytic effect.Air-flow behind the catalytic combustion of catalytic combustion Room 1 (2) (600 ℃～750 ℃), a part to economizer bank (5), is carried out preheating to boil-off gas by thermal current inlet tube (4), turns back to burning Room 2 (1) thereafter.Control valve (3) is used for regulating the temperature of catalytic combustion Room 1 (2).

Conclusion: 1) make catalyst keep active temperature (400 ℃～450 ℃) to need 50KW to heat, on average per hour heat four times, heated three minutes at every turn, need heat 4.8 hours in one day 24 hours, power consumption 240 degree adopt the utility model, save power consumption.

2) owing to constantly produce, produce continual solvent evaporation, continual catalytic combustion produces continual thermal current, and continual heating evaporation gas keeps the temperature of the uninterrupted required catalysis of catalyst, and catalyst can not poisoned.
