Description

Technical Field

[0001] This invention relates to the field of cooling and dust removal devices, and in particular to a rapid cooling and dust removal system for mining faces and its usage method. Background Technology

[0002] As the development of metal mineral resources gradually extends to deeper areas, deep-well mining environments face a combination of challenges, including high temperatures and excessive dust concentrations. Traditional ventilation and cooling systems are limited by uneven airflow distribution and low heat exchange efficiency, making it difficult to meet the rapid cooling needs of deep-well working faces. Conventional dust removal equipment suffers from insufficient collection efficiency and secondary dust generation in high-dust scenarios such as blasting and transportation, and also has high energy consumption and maintenance costs.

[0003] While some dust removal and cooling synergistic treatment solutions have emerged in the prior art, they still have significant limitations. Patent application CN202411441755.5 discloses an integrated dust removal and cooling system and method for high-temperature mining faces. Although it achieves synergistic treatment of dust and heat hazards through multi-stage processing units, its end-stage reliance on filtration devices for dust adsorption and filtration leads to problems such as easy clogging of the filter media and the need for regular maintenance and replacement. Furthermore, the system uses electronic control devices and fuzzy PID algorithms, limiting its applicability in enclosed mining spaces lacking power supply facilities. Summary of the Invention

[0049] Please see Figure 1 , Figure 2 and Figure 3According to an embodiment of the present invention, a rapid cooling and dust removal system for a mining face includes a gas mixing device 100, a cooling component 200, a gas flow regulating component 300, a gas-water mixing device 400, a water flow regulating component 500, and a nozzle 600. The gas mixing device 100 has a gas mixing chamber 110 inside. The cooling component 200 is connected to the gas mixing chamber 110 via a pipeline and is used to supply cold air into the gas mixing chamber 110. The gas flow regulating component 300 is connected to a gas supply pipeline 910, the gas mixing chamber 110, and the cooling component 200 via pipelines. The gas flow regulating component 300 is used to distribute the gas supplied from the gas supply pipeline 910 to the gas mixing chamber 110 and the cooling component 200 according to a preset ratio. The gas-water mixing device 400 has a gas-water mixing chamber 410 inside, which is connected to the gas mixing chamber 110 via a pipeline. The water flow regulating component 500 is connected to the water supply pipe 920 and the air-water mixing chamber 410 via pipelines. The water flow regulating component 500 is used to regulate the flow rate of the water delivered to the air-water mixing chamber 410. The nozzle 600 is connected to the air-water mixing chamber 410 and is used to spray the air-water mixture for cooling and dust removal.

[0050] The gas diversion and regulation component 300 is connected to an external gas supply pipeline 910, and the water flow regulation component 500 is connected to an external water supply pipeline 920. The system requires no external power supply, directly utilizing the existing high-pressure gas and water sources in the mine, ensuring safety and reliability, and is suitable for special working conditions such as flammable and explosive environments. In the gas-water mixing device 400, gas and water are directly mixed, eliminating the need for traditional water pumps and atomizers, resulting in a simple structure and low failure rate. The gas diversion and regulation component 300 regulates the gas ratio delivered to the cooling component 200 and the gas mixing chamber 110, thereby regulating the temperature of the mixed gas in the gas mixing chamber 110. The system integrates cooling and dust removal functions, is compact, and its modular design facilitates flexible deployment in narrow tunnels.

[0051] In some embodiments, see Figure 1 , Figure 2 and Figure 3The gas-water mixing device 400 is provided with a cold air inlet 420, a water jet inlet 430, and a gas-water mixture outlet 440, all of which are connected to the gas-water mixing chamber 410. The cold air inlet 420 and the gas-water mixture outlet 440 are respectively located at both ends of the gas-water mixing device 400 along its length. The water jet inlet 430 is located on the side wall of the gas-water mixing chamber 410. The cold air inlet 420 is connected to the gas mixing chamber 110, the gas-water mixture outlet 440 is connected to the nozzle 600, and the water jet inlet 430 is connected to the water flow regulating component 500. The water flow regulating component 500 includes a first water flow control valve 510, which regulates the flow rate of water delivered to the gas-water mixing chamber 410. High-speed, low-temperature air is input into the air-water mixing chamber 410 through the cold air inlet 420. The high-speed, low-temperature air directly impacts and atomizes the water flow input through the air-water mixing chamber 410. The water flow input through the air jet inlet 430 is atomized in situ through pneumatic shearing and ejection, generating a supersaturated low-temperature air-water mixture. This eliminates the need for traditional water pumps and atomizers, resulting in a simple structure and low failure rate.

[0052] In some embodiments, see Figure 1 , Figure 2 and Figure 4 A gradually increasing cross-sectional area airflow regulating duct 310 is connected between the gas diversion regulating component 300 and the gas mixing device 100. The cross-sectional area of ​​the gradually increasing cross-sectional area airflow regulating duct 310 gradually increases in the direction away from the gas diversion regulating component 300. The interior of the gradually increasing cross-sectional area airflow regulating duct 310 adopts a gradually expanding structure, gradually increasing the inner diameter of the cavity to reduce the gas flow velocity. By changing the cross-sectional area, the gas flow velocity and pressure are regulated.

[0053] In some embodiments, see Figure 1 , Figure 2 and Figure 3The gas mixing device 100 is provided with multiple perforated plates 120, which are evenly spaced apart. The gas mixing device 100 has a first mixing inlet 130, a second mixing inlet 140, and a mixing outlet 150. The first mixing inlet 130 and the second mixing inlet 140 are both located at one end of the gas mixing device 100 along its length, and the mixing outlet 150 is located at the other end of the gas mixing device 100 along its length. The surfaces of the multiple perforated plates 120 are perpendicular to the length of the gas mixing device 100. The first mixing inlet 130 is connected to the gas diversion and regulating component 300; the second mixing inlet 140 is connected to the cold air outlet of the refrigeration component 200; and the mixing outlet 150 is connected to the cold air inlet 420 of the gas-water mixing device 400. Multiple perforated plates 120 are installed in the gas mixing device 100 to achieve efficient mixing of cold air and split air through turbulent diffusion; this allows the air input from the gas splitting regulating component 300 and the cold air input from the refrigeration component 200 to be fully mixed to form a low-temperature gas with a relatively uniform temperature.

[0054] In some embodiments, see Figure 1 , Figure 2 and Figure 3 Two adjacent perforated plates 120 are spaced apart from the upper and lower inner walls of the gas mixing chamber 110, respectively. One perforated plate 120 is spaced apart from the upper inner wall of the gas mixing chamber 110, and the other perforated plate 120 is spaced apart from the lower inner wall of the gas mixing chamber 110. This makes the flow channel in the gas mixing chamber 110 S-shaped, increasing the total length of the gas flow channel and allowing the air input from the gas diversion and regulating component 300 and the cold air input from the refrigeration component 200 to mix thoroughly, forming a relatively uniform low-temperature gas.

[0055] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The refrigeration assembly 200 includes a vortex tube thermal separation module 210. The inlet of the vortex tube thermal separation module 210 is connected to the gas diversion and regulating assembly 300, and the cold gas outlet of the vortex tube thermal separation module 210 is connected to the gas mixing chamber 110. The vortex tube thermal separation module 210 is a straight-tube vortex tube that does not require external power and directly utilizes high-pressure gas to generate thermal separation. The vortex tube thermal separation module 210 does not require a pre-cooling process and can complete thermal separation within 30 seconds. The cold end outlet temperature range is -30℃ to +25℃, and the cold end response speed is ≤5 seconds.

[0056] In some embodiments, see Figure 1 , Figure 2 and Figure 3The rapid cooling and dust removal system for the mining face also includes a hot air cooling component 700, which includes a plate heat exchanger. The air inlet of the plate heat exchanger is connected to the hot air outlet of the vortex tube heat and cold separation module 210, and the water inlet of the plate heat exchanger is connected to a water flow regulating component 500. The water flow regulating component 500 includes a second water flow control valve 520, which controls the flow rate of water into the plate heat exchanger. The plate heat exchanger is a corrugated plate heat exchanger, and its cooling water is for single use and is discharged directly after cooling. A heat exchange temperature sensor 820 is installed at the exhaust port of the plate heat exchanger. The heat exchange temperature sensor 820 monitors the temperature of the gas discharged from the exhaust port of the plate heat exchanger, and then regulates the second water flow control valve 520. The plate heat exchanger adopts open direct-discharge cooling, eliminating the need for complex coolant circulation pumps, radiators, and storage containers, further simplifying the system and resulting in extremely low maintenance costs.

[0057] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The rapid cooling and dust removal system for the mining face also includes a feedback component 800, which includes an ambient temperature and dust monitor 810. The ambient temperature and dust monitor 810 is used to monitor the temperature and dust concentration in the environment. The ambient temperature and dust monitor 810 collects environmental parameters of the working face in real time, allowing workers to manually adjust the gas diversion regulating component 300 and the water flow regulating component 500 to control the airflow and water mist flow rate.

[0058] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The gas diversion and regulating assembly 300 includes a mechanical three-way regulating valve, allowing manual adjustment of the diversion ratio. The nozzle 600 is a Venturi fan-shaped nozzle 600, employing a Venturi-fan composite structure and made of ceramic-stainless steel composite material, which is wear-resistant and anti-fouling. The ambient temperature and dust monitor 810 achieves passive monitoring through a bimetallic strip and light scattering principle. Cooling and dust removal are achieved through a purely mechanical structure, offering fast response and low maintenance costs.

[0059] See Figure 1 , Figure 2 and Figure 3 A method for using a rapid cooling and dust removal system for a mining face according to an embodiment of this application includes the following steps:
