TECHNICAL FIELD
[0001] The application relates to the technical field of heat exchange, in particular to a rapid cooler. BACKGROUND
[0002] The cooler is a kind of heat exchange equipment, which can be used to cool fluids, gases or solid particles and other forms of materials, and water or air is usually used as the cooling agent to remove heat.
[0003] In the chemical field, reactions between different materials can produce gas and release a large amount of heat, resulting in a high temperature of the gas, and the temperature of the gas needs to be reduced to a set temperature before subsequent use.
[0004] The traditional gas cooling method is to make the high-temperature gas flow through the hollow tank body, and the cooling medium is located outside the tank body to absorb the heat of the high-temperature gas in the tank body.
[0005] However, the diameter of the tank body can be large, resulting in insufficient cooling of the gas around the axis of the tank body away from the cooling medium, so the length of the tank body needs to be lengthened to ensure the cooling effect, which will inevitably increase the cost of the cooler, and there is an obvious deficiency. SUMMARY
[0006] In order to improve the problem of high cost caused by poor rapid cooling effect of the gas, the application provides a rapid cooler.
[0007] The rapid cooler provided by the application adopts the following technical scheme: A rapid cooler, comprising an internal hollow, a pressure-bearing pipeline with an inlet opening for high-temperature gas to flow in at one end and closed at the other end, an inner core arranged in the pressure-bearing pipeline and a gap between the inner core and the pressure-bearing pipeline, an outlet chamber arranged outside the pressure-bearing pipeline in a ring shape and internally hollow, and an outlet opening arranged between the inner and outer sidewalls of the pressure-bearing pipeline relative to the outlet chamber.
[0008] By adopting the above technical scheme, the high-temperature gas enters the pressure-bearing pipeline from the inlet opening, and then flows through the gap between the pressure-bearing pipeline and the inner core. Since the gap is close to the cooling medium as a whole, the rapid cooling effect of the gas flow through the gap is improved, the high-temperature gas can be fully cooled in a shorter path, the length of the pressure-bearing pipeline is shortened, and the cost is saved.
[0009] Optionally, a plurality of outlet openings are circumferentially arranged on the pressure-bearing pipeline.
[0010] By adopting the above technical scheme, the number of outlet openings is increased, and the rapid cooling of large gas flow is suitable.
[0011] Optionally, the inner core comprises an inner tube which is hollow, one end is closed and the other end is open, and the closed end of the inner tube penetrates from the closed end of the pressure pipeline.
[0012] By using the above technical scheme, the cooling medium is introduced into the inner tube through the open end, and the cooling medium flows on the inner side and the outer side of the gap, thereby cooling the gas and improving the cooling effect and efficiency.
[0013] Optionally, the closed end of the inner tube is arranged in a tapered shape along the direction close to the gas inlet.
[0014] By using the above technical scheme, the tapered non-closed end can guide the high-temperature gas entering the pressure pipeline, so that the gas can flow more smoothly through the gap between the pressure pipeline and the inner tube.
[0015] Optionally, a reverse flow groove is circumferentially formed on the inner wall of the inner tube, a first micro-flow channel is formed in the side wall of the inner tube along the axial direction, a first liquid outlet chamber is arranged on the pipe outside the pressure pipeline, and the first liquid outlet chamber is hollow and connected to the reverse flow groove through the first micro-flow channel.
[0016] By using the above technical scheme, the cooling medium entering the inner tube flows into the first micro-flow channel from the reverse flow groove, and then flows into the first liquid outlet chamber and is discharged, so that the cooling medium in the inner tube circulates, the inflow and outflow of the cooling medium are separated and do not affect each other, and the cooling effect is further improved.
[0017] Optionally, a hollow second liquid outlet chamber and a third liquid outlet chamber are arranged outside the pressure pipeline, a second micro-flow channel is formed in the side wall of the pressure pipeline opposite the second liquid outlet chamber and the third liquid outlet chamber, and a flow pipe is connected between the first liquid outlet chamber and the second liquid outlet chamber.
[0018] By using the above technical scheme, the cooling medium in the first liquid outlet chamber enters the second liquid outlet chamber through the flow pipe, then flows through the second micro-flow channel to the third liquid outlet chamber, and is finally discharged from the third liquid outlet chamber. During the flow of the cooling medium from the second micro-flow channel, the high-temperature gas can be further heat-absorbed, and the quenching effect is improved.
[0019] Optionally, flanges are arranged outside the pressure pipeline and the inner tube, and the two flanges are bolted.
[0020] By using the above technical scheme, the pressure pipeline and the inner tube are detachably connected through the two flanges, which on the one hand realizes the quick disassembly of the pressure pipeline and the inner tube, and on the other hand facilitates the cleaning of the pressure pipeline and the inner tube.
[0021] In summary, the present application has at least one of the following beneficial technical effects: 1. High temperature gas enters the pressure pipeline from the gas inlet, and then flows through the gap between the pressure pipeline and the inner core. Since the gap is close to the cooling medium, the cooling effect of the gas flow through the gap is improved, and the length of the pressure pipeline is shortened, thereby saving the cost. 2. The cooling medium entering the inner tube flows into the first micro-channel from the backflow groove, flows into the first liquid outlet chamber, and then is discharged. In this way, the cooling medium in the inner tube circulates, and the inflow and outflow of the cooling medium are separated and do not affect each other, thereby further improving the cooling effect. 3. The cooling medium in the first liquid outlet chamber enters the second liquid outlet chamber through the flow pipe, and then flows through the second micro-channel to the third liquid outlet chamber, and finally is discharged from the third liquid outlet chamber. During the flow of the cooling medium from the second micro-channel, the high temperature gas can be further heat-absorbed, thereby improving the cooling effect. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0025] The following will be described in detail with reference to the accompanying drawings. Figures 1-2 The application will be further described in detail.
[0026] The embodiment of the application discloses a rapid cooler.
[0027] Reference Figure 1 The rapid cooler comprises a pressure pipeline 1 which is hollow, has a gas inlet 101 for high temperature gas to flow in at one end, and is open at the other end.
[0028] Reference Figure 1 The rapid cooler further comprises an inner core, and the inner core comprises an inner tube 3 which is hollow, is closed at one end, and is open at the other end. The closed end of the inner tube 3 is coaxially inserted into the pressure pipeline 1 from the end of the pressure pipeline 1 opposite to the gas inlet 101, and a gap is left between the two. The closed end of the inner tube 3 is arranged in a tapered shape along the direction close to the gas inlet 101.
[0029] Reference Figure 1 andFigure 2 The flange 7 is also welded on the pipe where the inner tube 3 is located outside the pressure pipeline 1, and when the inner tube 3 is completely inserted into the pressure pipeline 1, the two flanges 7 are bolted, and the flange 7 on the inner tube 3 seals the other end of the pressure pipeline 1 relative to the air inlet 101.
[0030] Referring to Figure 1 The air outlet chamber 2 is welded outside the pressure pipeline 1, which is ring-shaped and hollow inside, and the air outlet chamber 2 is close to the flange 7, and a plurality of air outlets 102 are arranged on the inner and outer walls of the pressure pipeline 1 relative to the position of the air outlet chamber 2, and the air outlet chamber 2 is used to discharge the rapidly cooled gas.
[0031] Referring to Figure 1 The high-temperature gas enters the pressure pipeline 1 from the air inlet 101, and the inner tube 3 is tapered at one end to guide the high-temperature gas into the gap between the pressure pipeline 1 and the inner tube 3.
[0032] When flowing through the gap, the cooling medium outside the pressure pipeline 1 absorbs the heat of the high-temperature gas, and since the gap is close to the cooling medium as a whole, the high-temperature gas can be fully and rapidly cooled, and the length of the pressure pipeline 1 can be shortened, thereby saving costs.
[0033] The rapidly cooled gas is discharged from the plurality of air outlets 102 into the air outlet chamber 2, and then the pipeline discharges from the air outlet chamber 2, and the number of air outlets 102 in the present application is large, so it can be suitable for large-flow gas rapid cooling.
[0034] Referring to Figure 1 A reverse flow groove 31 is arranged on the inner wall of the inner tube 3 close to the air inlet 101, and a plurality of first micro flow channels 32 parallel to the axis of the inner tube 3 are arranged on the inner wall of the inner tube 3, and a first liquid outlet chamber 4 is welded on the pipe where the inner tube 3 is located outside the pressure pipeline 1, which is ring-shaped, hollow inside and connected to the reverse flow groove 31 through the first micro flow channel 32.
[0035] Referring to Figure 1 The second liquid outlet chamber 5 and the third liquid outlet chamber 6 are welded on the outer wall of the pressure pipeline 1, and the second liquid outlet chamber 5 and the second liquid outlet chamber 5 are both ring-shaped and hollow inside, and the second liquid outlet chamber 5 and the first liquid outlet chamber 4 are connected by a flow pipe 8, and a plurality of second micro flow channels 103 parallel to the axis of the pressure pipeline 1 are arranged on the inner wall of the pressure pipeline 1, and the second micro flow channels 103 are connected to the second liquid outlet chamber 5 and the third liquid outlet chamber 6, and the third liquid outlet chamber 6 is also connected to the pipeline for discharging the cooling medium in the prior art.
[0036] Referring to Figure 1The cooling medium entering the inner tube 3 firstly enters the first micro flow channel 32 from the backflow groove 31, then flows into the first liquid outlet chamber 4 and then enters the second liquid outlet chamber 5 through the flow pipe 8, then flows into the third liquid outlet chamber 6 through the second micro flow channel 103, and finally is discharged.
[0037] During the flowing of the cooling medium through the inner tube 3, the backflow groove 31, the first micro flow channel 32, the first liquid outlet chamber 4, the second liquid outlet chamber 5 and the second micro flow channel 103, the high-temperature gas in the above-mentioned gap can be cooled from the inner side and the outer side at the same time, the heat exchange time is prolonged without increasing the length of the pressure-bearing pipeline, and thus the quenching effect and efficiency are improved.
[0038] The application can be flexibly changed according to actual requirements, and the cooling medium on the inner side and the outer side can be replaced by a high-temperature medium to heat the material flowing therethrough. However, in actual application, the cooling application is more common, and the heating application is relatively less common.
[0039] The implementation principle of the embodiment of the application is as follows: the high-temperature gas enters the pressure-bearing pipeline 1 from the gas inlet 101, and the inner tube 3 guides the high-temperature gas to the gap between the pressure-bearing pipeline 1 and the inner tube 3. When flowing through the gap, the cooling medium outside the pressure-bearing pipeline 1 absorbs the heat of the high-temperature gas, the quenched gas is discharged from the multiple gas outlets 102 to the gas outlet chamber 2, and finally is discharged from the gas outlet chamber 2.
[0040] The cooling medium entering the inner tube 3 firstly enters the first micro flow channel 32 from the backflow groove 31, then flows into the first liquid outlet chamber 4 and then enters the second liquid outlet chamber 5 through the flow pipe 8, then flows into the third liquid outlet chamber 6 through the second micro flow channel 103, and finally is discharged.
[0041] During the flowing of the cooling medium through the inner tube 3, the backflow groove 31, the first micro flow channel 32, the first liquid outlet chamber 4, the second liquid outlet chamber 5 and the second micro flow channel 103, the high-temperature gas in the above-mentioned gap can be cooled from the inner side and the outer side at the same time.
[0042] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
