Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sugar manufacturing equipment, and in particular to a sugar factory wastewater cooling pool. BACKGROUND

[0002] At present, some high-temperature wastewater is generated in the process of sucrose production, and therefore, before the wastewater is discharged, the wastewater needs to be treated because the wastewater contains a large amount of organic matter and ammonia nitrogen. At present, the main treatment method is a microbial treatment method, which consumes the organic matter and ammonia nitrogen in the wastewater by adding bacterial strains into the wastewater. In the treatment process, because the temperature of the high-temperature wastewater is 40-45 DEG C, and the optimal growth temperature of the treatment bacteria is 25-30 DEG C, the wastewater needs to be cooled before being discharged into the treatment pool. For example, a cooling treatment system for boiled sugar wastewater is disclosed in Chinese Patent No. 202023080158.4, which comprises a wastewater receiving pool, an adjusting pool, a biological purification pool and a cooling device. The wastewater receiving pool is used for receiving the wastewater generated by a sugar manufacturing production line. The adjusting pool is connected to the output end of the wastewater receiving pool. The biological purification pool is connected to the output end of the adjusting pool. The device exchanges heat between the cooling water in the circulating pipeline and the wastewater in the adjusting pool, so that the temperature of the wastewater in the adjusting pool is reduced. However, the heat exchange speed of the circulating pipeline is slow, and an additional heat dissipation source is needed to dissipate heat of the circulating water, which is high in cost and slow in speed. Therefore, a sugar factory wastewater cooling pool is needed, which can make the wastewater fall through a plurality of heat dissipation water tanks, and dissipate heat through a fan during the period, so as to be low in overall energy consumption, not need an additional heat dissipation source, and reduce the heat dissipation cost.

[0018] As shown in Figure 1 , Figure 2 An embodiment of the present application provides a sugar mill wastewater cooling pool, which comprises: a cooling pool body 1, a support table 2, a heat dissipation water tank 3, and a water inlet pipe 4. The cooling pool body 1 is embedded in the ground. The support table 2 is located on one side of the cooling pool body 1. An inclined surface is arranged on one side of the support table 2. The heat dissipation water tank 3 is installed on the inclined surface of the support table 2. One end of the water inlet pipe 4 is connected with a high-temperature wastewater pool, and the other end of the water inlet pipe 4 is connected with the heat dissipation water tank 3. The heat dissipation water tank 3 extends outward from the support table 2. A drainage hole 5 is arranged on one side of the heat dissipation water tank 3. A heat dissipation fan 6 is arranged at the lower part of the heat dissipation water tank 3. The air outlet direction of the heat dissipation fan 6 is towards the lower part of the drainage hole 5.

[0019] The high-temperature wastewater flows into the uppermost heat dissipation tank 3 from the high-temperature wastewater pool through the water inlet pipe 4, and the wastewater in the heat dissipation tank 3 flows out through the drain hole 5. Since the drain hole 5 is filled with gravel particles 8, the wastewater is dispersed into small water droplets when passing through the gravel particles 8, and the air blown by the heat dissipation fan 6 exchanges heat with the small water droplets during the falling of the small water droplets, thereby reducing the temperature of the small water droplets. The air volume of the heat dissipation fan 6 is controlled to avoid blowing the small water droplets out of the heat dissipation tank 3. The support table 2 is provided with multiple heat dissipation tanks 3, and the wastewater can be subjected to multiple air cooling heat exchange, thereby effectively reducing the temperature of the wastewater. The cooled wastewater flows into the cooling pool body 1. The cooling pool body 1 is provided with a temperature sensor. When it is detected that the temperature of the wastewater in the cooling pool body 1 is still high, the circulating pump 10 is started to make the wastewater in the cooling pool body 1 flow onto the top heat dissipation tank 3 again, and the temperature of the wastewater in the cooling pool body 1 is reduced through multiple air cooling heat dissipation. When it is detected that the temperature of the wastewater in the cooling pool body 1 is low, the air volume of the heat dissipation fan 6 is reduced or the heat dissipation fan 6 is turned off, thereby reducing the temperature loss of the wastewater during falling and making the hot wastewater flow into the cooling pool body 1 to increase the temperature of the wastewater. Through the above measures, the temperature of the wastewater in the cooling pool body 1 meets the best growth temperature range of bacteria, and the speed of bacteria in treating organic matter and ammonia nitrogen in the wastewater is increased when the wastewater in the cooling pool body 1 is introduced into the treatment pool, thereby improving the efficiency and quality of wastewater treatment. The entire device has low energy consumption and does not require additional heat dissipation sources, thereby reducing the cost of heat dissipation.

[0020] In a specific embodiment, the bottom of the drain hole 5 is provided with a blocking net 7, and the drain hole 5 is filled with gravel particles 8. The blocking net 7 is used to block the gravel particles 8 to prevent the gravel particles 8 from falling. The gravel particles 8 have multiple holes therebetween, and the wastewater is dispersed into small water droplets when passing through the gravel particles 8, thereby increasing the heat exchange area to facilitate the air blown by the heat dissipation fan 6 to cool the wastewater.

[0021] Preferably, the drain hole 5 is a horn-shaped hole with a large upper part and a small lower part. The blocking net 7 is attached to the inner wall of the drain hole 5 on both sides, and multiple steel bars are arranged on the blocking net 7 at intervals to fixedly install the blocking net 7 at the lower part of the drain hole 5 to block the gravel particles 8 from falling.

[0022] Preferably, the heat dissipation tank 3 has multiple heat dissipation tanks 3 arranged on the inclined surface of the support table 2 in a top-to-bottom manner, and the drain hole 5 of the upper heat dissipation tank 3 is located below the upper heat dissipation tank 3. Multiple heat dissipation tanks 3 are arranged to perform multiple air cooling heat dissipation on the wastewater, thereby improving the cooling effect and making the temperature of the treated wastewater meet the best growth temperature range of bacteria.

[0023] In a preferred embodiment, the lower parts of the heat dissipation tanks 3 are connected to each other through support columns 9 to improve the stability of the heat dissipation tanks 3 and prevent the heat dissipation tanks 3 from collapsing.

[0024] Preferably, the cooling pool body 1 is provided with a circulating pump 10, the water inlet end of the circulating pump 10 is connected with the cooling pool body 1, and the water outlet end of the circulating pump 10 is connected with the uppermost heat dissipation water tank 3. When the temperature of the waste water in the cooling pool body 1 is relatively high, the waste water can flow to the heat dissipation water tank 3 through the circulating pump 10 for air cooling heat dissipation again, so as to effectively control the temperature of the waste water in the cooling pool body 1.

[0025] Of course, the present application can have other various embodiments, and based on the embodiments, other embodiments obtained by those skilled in the art without any creative labor shall fall within the scope of the present application.
