Description

Technical Field

[0001] This utility model relates to the technical field of furfural processing equipment, specifically a circulating cooling device for furfural processing. Background Technology

[0002] Furfural, also known as 2-furan carbaldehyde, was originally produced by heating rice bran with dilute acid, hence the name furfural. Furfural is formed by the hydrolysis of pentosans to pentoses under the action of acid, followed by the dehydration and cyclization of pentoses. Cooling equipment is required during the processing.

[0003] The prior art discloses a circulating cooling device for furfural processing, with announcement number CN220852739U, relating to the field of biochemical technology. It includes a base plate, a processing box located at the center of the top of the base plate, and cooling components on both sides of the top of the base plate. The cooling components include two cooling boxes, two bow-shaped circulation pipes, and auxiliary components. The two cooling boxes are respectively located on both sides of the top of the base plate, and the two bow-shaped circulation pipes are respectively inserted into the interior of the two cooling boxes. A first water pump and a second water pump are located on both sides of the top of each of the two cooling boxes. The beneficial effect of the above device is that the first and second water pumps in the cooling components work together to drive water to circulate in the bow-shaped circulation pipes. The flow of water causes heat adsorption, facilitating water circulation. The circulated water is introduced into a storage tank, where a semiconductor cooler facilitates cooling of the water in the storage tank.

[0004] The aforementioned circulating cooling device for furfural processing uses an electric hydraulic cylinder in the auxiliary components to drive a slider to move within a chute. The movement of the slider causes two cooling boxes to move relative to each other and come into contact with the processing box, facilitating cooling of the processing box and allowing for easy adjustment of the operating distance, thus improving cooling efficiency. However, the aforementioned furfural processing cooling device does not employ a zoned cooling structure; instead, it cools all components together, making it impossible to provide specialized cooling for different temperature stages during furfural processing. Consequently, its performance is poor and requires improvement. Utility Model Content

Then, the spray pump 413 and spray pipe 414 are used to spray the cooling medium onto the furfural raw material inside, employing a highly efficient cooling medium spraying or immersion method to quickly lower the temperature of the furfural. The furfural raw material requiring rapid cooling is input through the first conveying pipe 302. When necessary, the flow control valve 307 needs to be closed. The second cooling cylinder 402 and the third cooling cylinder 403 are medium and low temperature cooling zones, using ordinary cooling methods, utilizing the heat conduction of the inner wall of the inner heat-conducting shell 404 for cooling.

The conveying methods are different. The flow control valve 307 is used to control the feeding of the second conveying pipe 303. When high-temperature treatment is required, it is closed to prevent the raw material from entering the low-temperature cooling zone of the second cooling cylinder 402. The method of zoned cooling treatment of furfural can be used to carry out special cooling for different temperature stages in the furfural processing process, ensuring that the furfural temperature finally reaches the ideal cooling temperature.
