Technical Field

[0001] The utility model relates to the technical field of circulating cooling water for calcium carbide furnaces, in particular to a circulating cooling water temperature reduction device for calcium carbide furnaces. Background Art

[0002] When the calcium carbide furnace is in use, circulating cooling water needs to be introduced to cool the contact elements to ensure the normal operation of the calcium carbide furnace. The water temperature of the circulating cooling water increases after heat exchange with the calcium carbide furnace, and the self-cooling effect of the circulating cooling water pipeline of the existing calcium carbide furnace is poor. After the calcium carbide furnace has been working for a period of time, the temperature of the circulating cooling water itself will be too high, thereby failing to cool the contact elements properly, resulting in the calcium carbide furnace being unable to operate normally. Summary of the invention

DETAILED DESCRIPTION

[0012] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.

[0013] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached manual. Figure 1 The positional relationships such as front, back, top, bottom, left, and right are described according to the layout directions of the drawings in the specification.

[0014] The present invention is further described below in conjunction with the embodiments and drawings:

[0015] As attached Figure 1As shown, the calcium carbide furnace circulating cooling water temperature reduction device includes a cooling water tank 1, a water outlet pipeline 2, a water return pipeline 3, a heat exchanger 4, a heat dissipation fan 5, a cooling tower 6, a first circulation pump 7, a second circulation pump 8, a first water distributor 9 and a second water distributor 10. The cooling tower 6 is provided with a heat exchanger 4, and a spray pipeline 11 is provided in the cooling tower 6 above the heat exchanger 4. The spray pipeline 11 is provided with a plurality of spray nozzles 12 with openings facing downwards. The top of the cooling tower 6 is provided with an air outlet, and the air outlet is provided with a heat dissipation fan 5. The bottom of the cooling tower 6 is shaped A return water pool 13 is formed, and the return water pool 13 is connected with the spray pipeline 11 through a water supply pipeline 14. A first circulation pump 7 is arranged on the water supply pipeline 14. An air inlet is arranged on the side wall of the cooling tower 6 at a position between the heat exchanger 4 and the return water pool 13. The water outlet of the cooling water tank 1 is connected with the inlet end of the heat exchanger 4 through the water outlet pipeline 2. A second circulation pump 8 is arranged on the water outlet pipeline 2. The outlet end of the heat exchanger 4 is connected with the first water distributor 9 through a connecting pipeline. The return water outlet of the cooling water tank 1 is connected with the second water distributor 10 through the return water pipeline 3.

[0016] When in use, the cooling water inlet of each contact element of the calcium carbide furnace 17 is connected to the first water distributor 9 through a pipeline, and the cooling water outlet of each contact element of the calcium carbide furnace 17 is connected to the second water distributor 10 through a pipeline, cooling water is injected into the cooling water tank 1, and spray water is injected into the return water tank 13. The first circulation pump 7, the second circulation pump 8 and the heat dissipation fan 5 are started. When the cooling water enters the heat exchanger 4, the cooling water is cooled by the heat dissipation fan 5 and the spray water sprayed by the spray nozzle 12, thereby preventing the cooling water from overheating during circulation, thereby ensuring the cooling effect of the cooling water on the contact elements of the calcium carbide furnace; specifically, the heat exchanger 4 is a fin heat exchanger 4.

[0017] The above embodiments may be further optimized and / or improved according to actual needs:

[0018] As attached Figure 1 As shown, the bottom wall of the return water pool 13 is inclined from left to right and from top to bottom, and a mud discharge pipeline 18 is provided at the lowest point of the bottom of the return water pool 13, and a mud discharge valve 19 is provided on the mud discharge pipeline 18. The spray water sprayed from the spray nozzle 12 will inevitably carry dust in the air when it falls back to the return water pool 13. The accumulation of dust in the spray water will not only block the spray nozzle 12, but also the muddy spray water will adhere to the outside of the heat exchanger 4, thereby reducing the heat exchange efficiency. The bottom wall of the return water pool 13 is designed to be inclined and the mud discharge pipeline 18 is provided, so that the sludge is easily discharged and the spray water sprayed from the spray nozzle 12 is ensured to be clean.

[0019] Specifically, as attached Figure 1As shown, the upper part of the return water tank 13 is sequentially provided with a first water baffle 15 and a second water baffle 16 at intervals from top to bottom. The first water baffle 15 is tilted from left to right and from bottom to top. The right end and the front and rear ends of the first water baffle 15 are fixedly connected to the inner wall of the return water tank 13, and a first water drop gap is formed between the left end of the first water baffle 15 and the inner wall of the return water tank 13. The second water baffle 16 is tilted from left to right and from top to bottom. The left end and the front and rear ends of the second water baffle 16 are fixedly connected to the inner wall of the return water tank 13, and a second water drop gap is formed between the right end of the second water baffle 16 and the inner wall of the return water tank 13. According to the needs, when spray water is injected into the return water tank 13, it is ensured that the right end of the second water baffle 16 is located below the liquid level of the return water tank 13 when the spray water is circulated. Compared with the spray water directly dripping back into the return water tank 13, the first water baffle 15 and the second water baffle 16 are set in the present application. When the spray water falls back, it first drips on the first water baffle 15, and then flows back to the return water tank 13 along the first water baffle 15 and the second water baffle 16, thereby reducing the water fluctuation in the return water tank 13 when the spray water flows back, and preventing the sludge settled in the tank from being stirred up.

[0020] The above technical features constitute the best implementation example of the present utility model, which has strong adaptability and best implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
