technical field

The utility model relates to an enameled wire production equipment, in particular to an enameled wire oven waste gas heat utilization device.

Background technique

At present, in the prior art, the waste gas produced by enameled wire production ovens is generally directly discharged into the air, and these waste gases contain high heat energy. Direct discharge of this waste gas containing high heat energy will not only waste The heat contained in the exhaust gas will also cause certain pollution to the atmospheric environment. The existing method of directly discharging exhaust gas is not ideal enough. Therefore, it is necessary to provide an enameled wire oven system that can not only reutilize the heat energy in the waste gas, but also reduce the pollution to the environment.

Utility model content

The technical problem to be solved by the utility model is to provide a new enameled wire oven waste gas heat energy utilization device, and the enameled wire oven waste gas heat energy utilization device can fully utilize the heat of the waste gas generated as the protective gas for wire annealing, on the one hand Energy saving, on the one hand, greatly reduces the pollution and damage to the atmospheric environment.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: an enameled wire oven waste gas heat energy utilization device, including: an enameled wire oven, which is used to bake the paint on the outer layer of the wire to form an insulated wire; A waste gas discharge pipe is arranged on the enameled wire oven to discharge the waste gas generated during the baking process; a heat exchanger is installed on the waste gas discharge pipe, which has an inlet and a corresponding outlet, wherein the inlet The outlet is used to feed a fluid medium capable of absorbing the heat of the exhaust gas, and the outlet is connected to an annealing furnace, and is used to feed the medium absorbing the heat of the exhaust gas into the annealing furnace as a protective medium for the annealing of the wire.

When the hot exhaust gas in the enameled wire oven passes through the heat exchanger, most of the heat in it is absorbed by the medium (such as water) in the heat exchanger. Therefore, the utility model absorbs the heat energy in the exhaust gas to generate steam, which is used as an annealing device for copper wires. When the protective gas, make full use of the wasted heat, turn waste into treasure, greatly reducing energy consumption. In addition, the temperature of the hot exhaust gas will be greatly reduced, and the exhaust gas with reduced temperature will be discharged into the atmosphere, which will greatly reduce its pollution to the environment. Therefore, compared with the prior art, the utility model has the advantages of reducing environmental pollution and good energy saving effect.

Description of drawings

Fig. 1 is a structural schematic diagram of the utility model enameled wire oven waste gas thermal energy utilization device.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further illustrated and described.

This enameled wire oven waste gas heat utilization device 10 includes an enameled wire oven 1 on which an exhaust gas discharge pipe 2 is installed, wherein the enameled wire oven 1 is to plate insulating varnish on the wire during the production process of the enameled wire, such as copper , aluminum or alloy wires, since the enameled wire insulating varnish used contains up to 60-70% organic solvents (such as cresol, xylene, etc.) and thinners, these will volatilize under high temperature conditions, resulting in exhaust gas. Under normal circumstances, the discarding temperature is generally above 400°C. The waste at such a temperature is directly discharged into the atmosphere, which will actually bring great pollution to the environment and directly waste a large amount of heat, which is not conducive to energy conservation.

In order to solve the above problems, a heat exchanger 4 is arranged on the exhaust gas discharge pipe 2, and the exhaust gas can pass through the heat exchanger 4. On the other hand, the heat exchanger 4 has an inlet and an outlet, wherein the inlet can absorb Medium for exhaust heat, such as water. The outlet is connected to an annealing furnace (not shown in the figure), water enters the heat exchanger from the inlet, and high-temperature waste passes through the heat exchanger at the same time. At this time, the high-temperature waste gas will heat the flowing water. It is usually above 400°C, so the water flowing into the heat exchanger will be heated to become water vapor, and then flow into the annealing furnace through the outlet, as a protective gas for wires, such as copper wires.

In order to achieve a better technical effect, this embodiment is made on the basis of the above embodiments, that is, a water inlet pipe 6 is connected to the inlet for passing in water or other fluid media. Correspondingly, a steam pipe 5 is also connected at the outlet, and the other end of the steam pipe 5 is connected with an annealing furnace (not shown in the figure). In this way, the generated steam passes through the steam pipe 5 into an annealing furnace (not shown in the figure), so as to serve as a shielding gas for wire annealing.

In order to make the hot waste gas in the enameled wire oven waste gas heat utilization device concentrated, continuous and stable discharge, a fan 3 can be installed in the waste gas discharge pipeline 2 in the above two embodiments, so that the waste gas can be more concentrated, Continuous and stable discharge.

Of course, the water inlet pipe 6 can actually be connected to other fluid media, as long as it can absorb the heat of the exhaust gas in the heat exchanger 4 .

It should be noted that, in order to allow the heat of the exhaust gas to be fully absorbed by water or other media, the water or other media may pass through the heat exchanger 4 for a longer time. For example, adding a path (not shown in the figure) passing through the heat exchanger 4 is easily understood by those skilled in the art, so it will not be repeated here.

It can be seen from the above that the utility model absorbs the heat energy in the exhaust gas to generate steam, which is used as the protective gas during the annealing of copper wires, fully utilizes the discarded heat energy, turns waste into treasure, and greatly reduces energy consumption. In addition, the temperature of the hot exhaust gas will be greatly reduced, and the exhaust gas with reduced temperature will be discharged into the atmosphere, which will greatly reduce its pollution to the environment. Therefore, compared with the prior art, the utility model has the advantages of reducing environmental pollution and good energy saving effect. In addition, the utility model has a simple structure and can reduce costs at the same time.

The above are just multiple embodiments of the utility model, and should not limit the scope of implementation of the utility model, that is, generally make simple equivalent changes and modifications according to the claims of the utility model and the content recorded in the specification , all belong to the scope covered by the claims of the present invention. In addition, the abstract and the title are only used to assist in the search of patent documents, and are not used to limit the scope of the claims of the present utility model.
