Description

Technical Field

[0001] This utility model belongs to the technical field of waste heat recovery equipment, and in particular relates to a comprehensive utilization device for waste heat in mines. Background Technology

[0002] During mining operations, a large amount of waste heat is generated. This waste heat mainly comes from several sources. First, during long-term operation, mining production equipment generates a large amount of heat due to mechanical friction and electrical energy conversion. For example, equipment such as ventilators, hoists, and air compressors will emit a lot of heat when they are running. Second, coal in the mine will also release heat due to oxidation during mining and transportation. In addition, mine drainage also contains a large amount of heat. This mine drainage is usually relatively high in temperature and has a stable volume.

[0003] Existing waste heat utilization devices have simple structures and can only utilize one type of waste heat resource. They cannot achieve comprehensive and efficient utilization of multiple types of waste heat. During the waste heat collection process, the heat exchange efficiency is low, resulting in a large amount of heat loss. The treatment effect on the flue gas generated during the waste heat utilization process is poor, making it difficult to meet increasingly stringent environmental emission standards.

[0004] To address these issues, we provide a comprehensive mine waste heat utilization device. Utility Model Content

[0005] The purpose of this utility model is to provide a comprehensive utilization device for mine waste heat. By combining the waste heat collection component and the flue gas treatment mechanism, it solves the problem that the existing waste heat utilization devices have simple structures and can only utilize a single type of waste heat resource, and cannot achieve comprehensive and efficient utilization of multiple types of waste heat.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a comprehensive utilization device for waste heat in mines, comprising a base frame, a heat storage box fixedly connected to the top of the base frame, a waste heat collection assembly fixedly connected to one side of the heat storage box, and a flue gas treatment mechanism fixedly connected to the other side of the heat storage box. The waste heat collection assembly includes a conveying pipe, one side of which is connected to the heat storage box, and another side of which is connected to a fan. A connecting pipe is connected to one side of the fan. One side of the conveying pipe penetrates one side of the heat storage box and extends into the inner cavity of the heat storage box. A first heat exchange pipe is connected to one side of the conveying pipe. A cooling water waste heat pipe is connected to the bottom of one side of the heat storage box, and one side of the cooling water waste heat pipe penetrates into the inner cavity of the heat storage box. A second heat exchange pipe is connected to one side of the cooling water waste heat pipe. The fan provides stable and strong suction to collect the waste heat. The heat source is transported to the heat storage box, and the connecting pipe can be flexibly connected to different waste heat generation points in the mine, such as mine production equipment and coal transportation channels, to achieve the collection of various waste heat sources. When the conveying pipe passes through one side of the heat storage box, a sealing rubber ring is set at the interface to ensure airtightness. The first heat exchange pipe adopts a U-shaped coil structure to increase the contact area with the heat storage medium in the heat storage box and improve the heat exchange efficiency. The cooling water waste heat pipe is connected to the second heat exchange pipe, which further enhances the heat exchange effect with the heat storage medium. The conveying pipe is sealed to the flange of the heat storage box to ensure no leakage during the waste heat collection process. The fan provides stable suction and can quickly transport waste heat from different sources in the mine to the heat storage box. The flexible connection method of the connecting pipe enables the device to adapt to different waste heat collection scenarios and achieve comprehensive collection of various waste heat resources.

[0009] The present invention is further configured such that a fixed base is fixedly connected to the bottom of the outer shell, and one side of the fixed base is fixedly connected to the heat storage box.

The drain pipe 12 can promptly drain the water after heat exchange in the second heat exchange tube 36, avoiding water accumulation that may affect the heat exchange effect and normal operation of the equipment.

[0031] The working principle of this utility model is as follows: After the fan 32 is started, the waste heat resources from different waste heat generation points such as mine production equipment and coal transportation channels are collected through the connecting pipe 33. The collected waste heat is transported to the heat storage box 2 through the conveying pipe 31. The waste heat entering the heat storage box 2 increases the contact area with the heat storage medium in the heat storage box 2 through the first heat exchange pipe 34, thereby efficiently transferring heat to the heat storage medium. At the same time, the waste heat of the cooling water in the mine enters the heat storage box 2 through the cooling water waste heat pipe 35, and the heat exchange effect with the heat storage medium is further enhanced by the second heat exchange pipe 36, so as to realize the comprehensive collection and efficient utilization of various waste heats.

[0032] The flue gas generated during the waste heat utilization process enters the discharge pipe 41 through the first heat exchange tube 34, and then enters the outer shell 42. The adsorption layer 44 first adsorbs the harmful gases and impurities in the flue gas, the filter layer 45 further intercepts the particulate matter in the flue gas, and finally the catalytic layer 46 catalyzes the remaining harmful gases into harmless substances. Through this series of treatments, the flue gas is purified, reducing environmental pollution and reducing the corrosion of downstream equipment by harmful flue gas, thus ensuring the stable operation and service life of the entire device.
