Description

Technical Field

[0001] The invention belongs to the field of air temperature regulation, and in particular relates to a connectable multi-channel air temperature regulation device and an application thereof. Background Art

[0002] Regulating air temperature is of great significance to people's daily life and industrial production. People's living and working spaces need suitable air temperatures, and industrial production spaces also need suitable air temperatures. The temperature in most areas of northern my country is relatively low in winter. When there is water or moisture in the shaft wall of the mine's air intake tunnel, the temperature of the fresh airflow entering the shaft is very low, which can easily cause freezing and form ice cones. The breaking and falling of ice cones will seriously threaten the safety of personnel and equipment and cause accidents. Therefore, airflow preheating equipment is usually set up to preheat the air entering the mine shaft to alleviate the freezing phenomenon. With the gradual depletion of shallow mineral resources, my country's mineral resource mining has begun to shift to deep mining. Heat damage is common in deep mines. The deeper the ore deposit is, the higher the ground temperature is, and the higher the air temperature in the mine tunnel is. Some can even reach a high temperature of more than 30°C, which seriously affects the health and safety of underground personnel. Therefore, it is necessary to take cooling measures and set up cooling equipment to adjust the air temperature underground.

[0003] In the plateau area of ​​northwest my country, high-altitude and deep mines have long faced the complex problem of low temperature and low pressure on the ground, but high temperature and humidity underground. This problem is particularly prominent during the mine infrastructure construction period. The surface air temperature in high-altitude and cold regions is low, and the wellhead is very easy to freeze, requiring air preheating all year round. In addition, since it is difficult to form a complete ventilation system during the mine infrastructure construction period, there are many dead-end tunnels, the surrounding rock temperature is high, and the ventilation environment is poor, the hot and humid air in the tunnel is difficult to discharge, resulting in high air temperature in the tunnel, greatly reducing the work efficiency of underground personnel and mechanical equipment. This phenomenon of two extreme temperatures on the ground and underground further forces the extension of the mine infrastructure construction period, resulting in increased mining costs and affecting the economic benefits of the enterprise.

[0004] Traditional mine wellhead antifreeze usually uses boiler steam preheating or geothermal preheating, but boiler steam preheating has shortcomings such as high energy consumption and large heat loss, and steam carries a large amount of water vapor into the mine, which will further increase the air humidity in the mine. If there is a heat damage problem in the mine, using boiler steam preheating will cause the problem to worsen further and increase the difficulty of cooling the air underground. Geothermal preheating is achieved by using air to exchange heat with the surrounding rock mass to gradually increase the air temperature. It is necessary to expose a large area of ​​the rock mass and emit enough heat to meet the preheating requirements, which has the problems of high cost and low efficiency. Traditional mine well cooling usually adopts measures such as ventilation cooling, reducing heat sources, mine mobile air conditioning units, or installing air coolers underground. Ventilation cooling is achieved by increasing air volume and wind speed, which has little effect in deep high-temperature dead-end tunnels or chambers where it is difficult to form ventilation circuits. When using mobile mining air-conditioning units or installing air coolers underground, the heat generated by the operation of the equipment itself will be directly dissipated into the mine, which is inconsistent with the measures to reduce heat sources. Summary of the invention

[0005] In response to the problems of wellhead antifreeze and underground heat damage faced by high-altitude deep mines, the present invention aims to provide a connectable multi-channel air temperature control device and its application.

The connector outer tube is sleeved on the outside of the connector inner tube. A plurality of guide support plates are provided between the connector inner tube and the connector outer tube at the connection with the channel host. One end of the connector inner tube is sealed and connected to the host inner tube through a sealing ring, and the other end is provided with an inner tube channel connecting port. One end of the connector outer tube is sealed and connected to the host outer tube through a sealing ring, and the other end is provided with an outer tube channel connecting port.

[0008] The channel main unit is provided with one or more channel main units, and the multiple channel main units are connected through sealing rings, and then the two ends are respectively connected to the first connecting piece and the second connecting piece through sealing rings.

[0012] The outer side of the outer wall of the main engine outer tube is wrapped with a thermal insulation layer.

[0013] An application of a connectable multi-channel air temperature regulating device, using the above-mentioned temperature regulating device, the device is used to cool the air in a conventional space, specifically comprising the following steps:

[0014] Step 1: A channel mainframe is used, and both ends of the channel mainframe are sealed and connected with the first connecting piece and the second connecting piece through sealing rings, the inner tube channel connecting port of the first connecting piece is connected to the connecting pipe I, and the outer tube channel connecting port of the first connecting piece is connected to the connecting pipe II, and the connecting pipe I and the connecting pipe II are connected in a conventional space at a distance; an air driving device is installed on the inner tube channel connecting port of the second connecting piece;

When the air passes through the host inner tube temperature conduction channel II, it absorbs cold energy and its temperature drops to low-temperature cold air. The low-temperature cold air enters the conventional space through the connecting pipe I;

[0016] Step 3: When the conventional space is a closed space, after the low-temperature cold air enters the closed space, the original high-temperature air in the closed space will enter the temperature conduction channel I of the channel host through the connecting pipe II, and the heat generated on the heating side of the semiconductor board will be absorbed by the air flowing through the temperature conduction channel I and discharged through the outer pipe channel connection port of the second connecting piece;

[0018] An application of a connectable multi-channel air temperature regulating device, using the above-mentioned temperature regulating device, the device is used to reduce the air temperature in a single-ended shaft of a mine, specifically comprising the following steps:

[0019] Step 1: A channel main unit is used, and both ends of the channel main unit are sealed and connected with the first connecting piece and the second connecting piece through sealing rings.

When the high-temperature air in the mine passes through the temperature-conducting channel II of the inner tube of the main engine, the temperature is reduced after absorbing the cold energy, and becomes low-temperature cold air. The low-temperature air enters the connecting pipe III through the inner tube channel connection port of the first connecting piece and is transported to the dead-end tunnel of the mine;

[0021] Step 3: Auxiliary fan I draws the dirty air in the mine's dead-end tunnel into connecting pipe IV, and enters the temperature conduction channel I of the channel main unit through the outer tube channel connecting port of the first connecting piece.

[0022] An application of a connectable multi-channel air temperature regulating device, using the above-mentioned temperature regulating device, the device is used in a high-cold deep mine to simultaneously achieve wellhead antifreeze and wellbore temperature reduction, specifically comprising the following steps:

[0023] Step 1: One channel host is used for cooling down the well, and both ends of the channel host are connected to the first connector and the second connector through sealing rings; two channel hosts are used for wellhead antifreeze, and the two channel hosts are connected and then connected to the first connector and the second connector through sealing rings;

[0024] The main unit of the channel for antifreeze at the wellhead and the first and second connecting pieces are placed on one side of the wellhead room on the ground.

The connecting pipe VII transmits the high-temperature gas to the wellhead room on the ground, enters the mine through the air shaft, and is used to preheat the wellhead air to prevent the wellhead from freezing;

[0026] Step 3: The underground cooling fan II draws the underground high-temperature gas into the underground cooling second connecting piece, and enters the temperature conducting channel II of the channel main unit. The semiconductor plate in the underground cooling channel main unit makes the temperature conducting channel II generate cold energy. The high-temperature gas absorbs the cold energy in the temperature conducting channel II and is cooled down to be converted into low-temperature cold air, and is transported to the air-demanding point through the connecting pipe X to meet the underground air cooling demand;

[0027] Step 4: The medium-driven pump drives the temperature-conducting medium inside the connecting pipes VIII and IX. The temperature-conducting channel I of the main unit of the channel for wellhead antifreeze conducts the cold generated by the refrigeration side of the semiconductor board, turning the temperature-conducting medium into a low-temperature medium. The flow of the temperature-conducting medium is used to cool the temperature-conducting channel I of the main unit of the channel for wellhead cooling.

[0056] The present invention provides a connectable multi-channel air temperature regulating device, which can be used to solve the problems of air circulation and temperature regulation in conventional spaces and dead-end shafts in mines, with a focus on solving the problem of two extreme temperatures above and below the shaft that has long been faced by high-altitude deep mines.

[0057] Example 1: The device of the present invention is applied to temperature regulation in a conventional space

[0058] The conventional space in this embodiment refers to conventional places where people live and work, including but not limited to residential houses, office places, industrial plants and other enclosed or non-completely enclosed spaces.

[0059] Fig. 9 The figure shows an application example of a connectable multi-channel air temperature regulating device for regulating temperature in a conventional space. In this example, only one channel host 2 is used to form the basic form of the device of the present invention, so as to reduce the air temperature in the conventional space 4. The side of the semiconductor board facing the host inner tube 201 of the channel host 2 is for cooling, and the other side is for heating; specifically, the cold energy generated by the cooling side of the semiconductor board 205 is conducted through the temperature conducting channel I 204 of the device of the present invention, thereby reducing the air temperature in the conventional space 4.

[0060] An application of a connectable multi-channel air temperature regulating device, which is used to cool the air in a conventional space 4, specifically comprises the following steps:

[0061] Step 1: A channel main unit 2 is used, and both ends of the channel main unit 2 are sealed and connected with the first connecting member 1 and the second connecting member 3 through a sealing ring 304. The inner tube channel connecting port of the first connecting member 1 is connected to the connecting pipe I 401, and the outer tube channel connecting port of the first connecting member 1 is connected to the connecting pipe II 402. The connecting pipe I 401 and the connecting pipe II 402 are connected in the conventional space 4 at a distance; an air driving device is installed on the inner tube channel connecting port 305 of the second connecting member 3, and the outer tube channel connecting port 306 of the second connecting member 3 is in contact with air;

[0062] Step 2: The semiconductor plate 205 on the main unit inner tube 201 faces the main unit inner tube 201 side for cooling, and the other side for heating; the air driving device draws external air into the temperature conducting channel II 208 of the channel main unit 2, and the semiconductor plate 205 generates cold energy on the cooling side. When the air passes through the temperature conducting channel II 208 of the main unit inner tube 201, it absorbs cold energy and is cooled down to be converted into low-temperature cold air. The low-temperature cold air enters the conventional space 4 through the connecting pipe I 401;

[0063] Step 3: When the conventional space 4 is a closed space, after the low-temperature cold air enters the closed space, the original high-temperature air in the closed space will enter the temperature-conducting channel I 204 of the channel host 2 through the connecting pipe II 402, and the semiconductor board 205 generates heat on the heating side, which is absorbed by the air flowing through the temperature-conducting channel I 204 and discharged through the outer tube channel connecting port 306 of the second connecting member 3; and the heating effect of the semiconductor board 205 on the air can form a pressure difference between the temperature-conducting channel I 204 and the closed space, driving the air in the closed space to flow into the temperature-conducting channel I 204 at an accelerated speed;

[0064] When the conventional space 4 is a non-enclosed space, that is, when there is some kind of communication path between the conventional space 4 and the outside world, the air pressure in the conventional space 4 is increased under the action of the air driving device on the inner tube channel connecting port 305 of the second connecting member 3. Therefore, after the low-temperature cold air enters the non-enclosed space, the original high-temperature air in the non-enclosed space will be discharged through other channels of the conventional space, and tap water is introduced into the outer tube channel connecting port 306 of the second connecting member 3. The low-temperature tap water enters the temperature conduction channel I 204 of the channel host 2 through the outer tube channel connecting port 306 of the second connecting member 3. The heating side of the semiconductor plate 205 generates heat.
