Description

Technical Field

[0001] The invention relates to the field of vehicle exhaust heat dissipation, and in particular to a heat dissipation device for a diesel-type trackless rubber-tyred vehicle. Background Art

[0002] Since most diesel engines of underground diesel trackless rubber-tyred vehicles are powered by explosion-proof diesel engines, they run slowly and carry heavy loads. During operation, the exhaust gas is large and the temperature is high, generally around 800°C. However, when the exhaust temperature is greater than 70°C, dust explosions are prone to occur, threatening the personal safety of workers and causing significant economic losses. Therefore, it is very important to cool down the high-temperature exhaust gas.

[0003] Most of the existing high-temperature exhaust gas cooling treatment equipment adopts wet exhaust gas treatment technology, that is, by passing the high-temperature exhaust gas into water and then cooling the high-temperature exhaust gas. However, when the high-temperature exhaust gas directly enters the water, a large number of exhaust bubbles will be generated, resulting in insufficient contact between the high-temperature exhaust gas and water, and the exhaust gas cooling rate is slow. Moreover, as the high-temperature exhaust gas is discharged, the high-temperature exhaust gas easily brings out a large amount of water vapor, resulting in insufficient water volume for subsequent cooling of the high-temperature exhaust gas. Insufficient water volume will lead to a decrease in the subsequent cooling efficiency of the high-temperature exhaust gas, which is not convenient for rapid cooling of the high-temperature exhaust gas.

[0010] Optionally, contact strips are also included, and a plurality of contact strips are fixedly connected to both sides of each hollow plate that contacts the outer wall.

[0011] Beneficial effects:

[0012] 1. When the operator starts the diesel engine, the diesel engine will discharge high-temperature exhaust gas into the exhaust gas treatment chamber through the exhaust port. The exhaust gas will enter the exhaust gas cooling chamber from the exhaust gas treatment chamber. The high-temperature exhaust gas will contact the outer walls of several hollow contact plates filled with water. The outer walls of the hollow contact plates will absorb the heat of the high-temperature exhaust gas, thereby cooling the high-temperature exhaust gas, making the exhaust gas temperature emitted by the diesel engine within an appropriate range, thereby making it safer for the rubber-tyred trackless vehicle to work in underground mines.

[0013] 2. When water flows into the guide pipe, the water flow will drive the two rotating blades to rotate, and the two rotating blades will stir the exhaust gas in the exhaust cooling chamber. The exhaust gas can be dispersed and contact the outer wall of the hollow plate more fully and thoroughly, so that the exhaust gas can be cooled more quickly, further improving the safety of the rubber-tyred trackless vehicle when working in the underground mine.

[0014] 3. The air pressure in the exhaust gas treatment chamber drives the push plate to move upward. The more the push plate moves upward, the more the large baffle moves upward. The large baffle no longer blocks the return pipe and the connector, so that more water can enter the atomizing head along the connector and be sprayed in the exhaust gas treatment chamber. Then the sprayed water mist can more fully contact with the high-temperature exhaust gas in the exhaust gas treatment chamber and absorb the heat of the high-temperature exhaust gas more quickly, thereby speeding up the cooling of the high-temperature exhaust gas.

[0015] 4. The sprayed water and the generated water vapor will carry some exhaust pollutants into the connecting pipe, and then flow back into the water tank along the connecting pipe, so that the water can be recycled, which is convenient for continuous and efficient cooling of high-temperature exhaust gas.

[0016] 5. The rotation of the impeller shaft drives several large rotating blades to rotate. The rotation of several large rotating blades will stir the high-temperature exhaust gas in the exhaust treatment chamber, making the high-temperature exhaust gas in the exhaust treatment chamber easy to disperse, so that the high-temperature exhaust gas in the exhaust treatment chamber can be more fully in contact with the sprayed water mist, so that the water mist can absorb the heat in the high-temperature exhaust gas more quickly, which is conducive to cooling the high-temperature exhaust gas more quickly.

The water inlet of the water pump 4 is connected to the water tank 3, and the side of the water pump 4 away from the water tank 3 is fixedly connected to the water supply pipe 5, and one end of the water supply pipe 5 is connected to the water outlet of the water pump 4. The exhaust gas treatment chamber 6 is fixedly connected to the diesel engine 2, and the exhaust gas treatment chamber 6 is connected to the exhaust port of the diesel engine 2. The exhaust gas treatment chamber 6 is fixedly connected to the exhaust gas cooling chamber 7 on the side away from the diesel engine 2. The exhaust gas treatment chamber 6 is located between the diesel engine 2 and the exhaust gas cooling chamber 7, and the exhaust gas cooling chamber 7 is connected to the exhaust gas treatment chamber 6. The exhaust gas treatment chamber 6 and the exhaust gas cooling chamber 7 are both cavity structures, and the circulating cooling mechanism is arranged on the exhaust gas cooling chamber 7.

[0032] The circulating cooling mechanism includes a fitted cooling plate 81, a guide pipe 82, a contact hollow plate 83, a return pipe 84 and a rotating blade rod 85. Two fitted cooling plates 81 are fixedly connected to the outer wall of the exhaust gas cooling chamber 7, one of which is fixedly connected to the other end of the water supply pipe 5, one of which is connected to the cooling plate 81 and communicates with the water supply pipe 5, a guide pipe 82 is fixedly connected between the two fitted cooling plates 81, another fitted cooling plate 81 is fixedly connected to the bottom end of the guide pipe 82, and another fitted cooling plate 81 is communicated with the guide pipe 82. A plurality of contact hollow plates 83 are fixedly connected to the exhaust gas cooling chamber 7, and the plurality of contact hollow plates 83 are staggered. Each contact hollow plate 83 is vertically arranged, and each contact hollow plate 83 There are two through holes on the upper part, and the two through holes on each contact hollow plate 83 are symmetrically arranged, and the two through holes on each contact hollow plate 83 are circular. One of the through holes on each contact hollow plate 83 is connected to one of the fitted cooling plates 81, and the other through hole on each contact hollow plate 83 is connected to the other fitted cooling plate 81. A return pipe 84 is fixedly connected to the top of the water tank 3, and the top of the return pipe 84 is fixedly connected to the guide pipe 82. The water tank 3 and the guide pipe 82 are both connected to the return pipe 84. Two rotating blade rods 85 are rotatably connected to the guide pipe 82, and each rotating blade rod 85 is rotatably connected to the exhaust gas cooling chamber 7 and the fitted cooling plate 81, and each rotating blade rod 85 is vertically arranged.

[0033] The device is installed on a trackless rubber-wheeled vehicle. In actual application, there is a certain amount of water in the water tank 3. When the trackless rubber-wheeled vehicle enters the mine for work, first, the operator starts the water pump 4, and the water in the water tank 3 flows into the water delivery pipe 5 through the water outlet of the water pump 4. The water flows into one of the contact cooling plates 81 along the water delivery pipe 5, and then the water flows into the contact hollow plate 83 through one of the through holes of the contact hollow plate 83. When each contact hollow plate 83 is full of water, the water will flow out of the contact hollow plate 83. Another through hole of the hollow plate 83 flows into another fitted cooling plate 81, and then the water will flow from the other fitted cooling plate 81 into the guide pipe 82, the water in the guide pipe 82 will flow into the return pipe 84, and finally part of the water will flow back into the water tank 3 through the return pipe 84, which can reduce the waste of water and thus recycle water resources. When the operator starts the diesel engine 2, the diesel engine 2 will discharge the high-temperature exhaust gas into the exhaust gas treatment chamber 6 through the exhaust port, and the exhaust gas The exhaust gas will enter the exhaust gas cooling chamber 7 from the exhaust gas treatment chamber 6, and the high-temperature exhaust gas will contact the outer walls of several contact hollow plates 83 filled with water. The outer walls of the contact hollow plates 83 will absorb the heat of the high-temperature exhaust gas, thereby cooling the high-temperature exhaust gas, so that the exhaust gas temperature emitted by the diesel engine 2 is within a suitable range, thereby making the trackless rubber-wheeled vehicle safer to work in the underground mine. In the process of water flowing into the guide pipe 82, the water flow will drive the two rotating blade rods 85 to rotate, and the two rotating blade rods 85 will stir the exhaust gas in the exhaust gas cooling chamber 7. The exhaust gas can be dispersed and can contact the outer walls of the contact hollow plates 83 more fully and thoroughly, so that the exhaust gas can be cooled more quickly, further improving the safety of the trackless rubber-wheeled vehicle when working in the underground mine. When the operator turns off the diesel engine 2, the diesel engine 2 no longer discharges high-temperature exhaust gas until the original high-temperature exhaust gas is cooled. The exhaust gas will be discharged from the exhaust gas cooling chamber 7, and then the operator can turn off the water pump 4.

[0034] Example 2

[0035] On the basis of Example 1, Figure 5-Figure 10 As shown, a spray mechanism is also included, which includes an atomizing head 91, a connecting head 92, a pushing plate 93, a large baffle plate 94 and a connecting pipe 95. The top of the exhaust gas treatment chamber 6 is rotatably connected to the atomizing head 91, and the top of the atomizing head 91 is rotatably connected to the connecting head 92. The upper part of the connecting head 92 is fixedly connected to the return pipe 84, and the connecting head 92 is communicated with the return pipe 84. The top of the exhaust gas treatment chamber 6 is slidably connected to the pushing plate 93, and the bottom of the pushing plate 93 is located in the exhaust gas treatment chamber 6. The top of the pushing plate 93 is fixedly connected to the large baffle plate 94, and the end of the large baffle plate 94 away from the pushing plate 93 is in contact with the connecting head 92 and the return pipe 84 at the same time. The bottom of the exhaust gas treatment chamber 6 is fixedly connected to the connecting pipe 95, and the end of the connecting pipe 95 away from the exhaust gas treatment chamber 6 is fixedly connected to the water tank 3, and the exhaust gas treatment chamber 6 and the water tank 3 are both communicated with the connecting pipe 95.

[0036] At first, the large baffle plate 94 blocks the return pipe 84 and the connector 92. When the high-temperature exhaust gas enters the exhaust gas treatment chamber 6, the air pressure in the exhaust gas treatment chamber 6 will drive the push plate 93 to move upward. The upward movement of the push plate 93 drives the large baffle plate 94 to move upward. The upward movement of the large baffle plate 94 will gradually no longer block the return pipe 84 and the connector 92, and the water in the return pipe 84 will gradually flow into the connector 92. The water then enters the atomizing head 91 from the connector 92 and is then sprayed out from the atomizing head 91. The more high-temperature exhaust gas in the exhaust gas treatment chamber 6, the stronger the air pressure in the exhaust gas treatment chamber 6, and the stronger the air pressure, the greater the distance the push plate 93 moves upward, the greater the distance the push plate 93 moves upward, the greater the distance the large baffle plate 94 moves upward, and the large baffle plate 94 no longer blocks the return pipe 84 and the connector 92, so that more water can The water mist can enter the atomizing head 91 along the connecting head 92 and be sprayed in the exhaust gas treatment chamber 6, and then the sprayed water mist can more fully contact with the high-temperature exhaust gas in the exhaust gas treatment chamber 6 and absorb the heat of the high-temperature exhaust gas more quickly, thereby accelerating the cooling speed of the high-temperature exhaust gas. The high-temperature exhaust gas contacts with water to generate a large amount of water vapor, and then the sprayed water and the generated water vapor will carry some exhaust gas pollutants and fall into the connecting pipe 95, and then flow back into the water tank 3 along the connecting pipe 95, so that the water can be recycled, which is convenient for continuously and efficiently cooling the high-temperature exhaust gas. When the diesel engine 2 is turned off and no longer discharges high-temperature exhaust gas, the push plate 93 and the large baffle 94 are reset under the action of their own gravity, and the end of the large baffle 94 away from the push plate 93 will block the reflux pipe 84 and the connecting head 92 again, and water will no longer flow into the connecting head 92.

[0037] Example 3

[0038] On the basis of Example 2, Figure 5-Figure 8 and Fig.11As shown, a disturbance mechanism is also included, which includes a mounting frame 101, a rotating impeller shaft 102, a small baffle 103, a water flow pipe 104 and a diverter pipe 105. The mounting frame 101 is fixedly connected to the side of the inner wall of the exhaust gas treatment chamber 6 close to the diesel engine 2. The mounting frame 101 and the rotating impeller shaft 102 are both arranged horizontally. The rotating impeller shaft 102 is rotatably connected between the exhaust gas treatment chamber 6 and the mounting frame 101. The rotating impeller shaft 102 is located directly below the atomizing head 91. The rotating impeller shaft 102 is provided with a plurality of large rotating blades and a small rotating blade. The impeller 93 is provided with a small baffle 103 fixedly connected to the push plate 93, and one end of the small baffle 103 away from the push plate 93 is slidably connected to the return pipe 84, and the return pipe 84 is fixedly connected with a water flow pipe 104 and a shunt pipe 105, and the lower part of the shunt pipe 105 is rotatably connected to the rotating impeller shaft 102, and the small rotating blades on the rotating impeller shaft 102 are located inside the shunt pipe 105, and the bottom end of the water flow pipe 104 is fixedly connected to the bottom end of the shunt pipe 105, and the water flow pipe 104 and the shunt pipe 105 are both connected to the return pipe 84, and the bottom end of the shunt pipe 105 is connected to the bottom end of the water flow pipe 104.

[0039] The push plate 93 moves upward, driving the large baffle plate 94 to move upward, while driving the small baffle plate 103 to move upward. The small baffle plate 103 moves upward and gradually blocks the return pipe 84. Most of the water flows into the connector 92 and the diverter pipe 105. Then, the water flow entering the diverter pipe 105 drives the small rotating blades in the diverter pipe 105 to rotate. The rotation of the small rotating blade drives the rotating impeller shaft 102 to rotate. The rotation of the rotating impeller shaft 102 drives a plurality of large rotating blades to rotate. The rotation will stir the high-temperature exhaust gas in the exhaust gas treatment chamber 6, making it easy to disperse the high-temperature exhaust gas in the exhaust gas treatment chamber 6, so that the high-temperature exhaust gas in the exhaust gas treatment chamber 6 can be in more complete contact with the sprayed water mist, so that the water mist can absorb the heat in the high-temperature exhaust gas more quickly, which is beneficial to cool down the high-temperature exhaust gas more quickly. After passing through the small rotating blades, the water flow will continue to flow into the water flow pipe 104 along the diversion pipe 105, and then the water flow will flow back into the reflux pipe 84 along the water flow pipe 104.

[0040] Example 4

[0041] On the basis of Example 3, Figure 5 As shown, it also includes a driving bevel gear 111 and a driven bevel gear 112. The driving bevel gear 111 is fixedly connected to one end of the rotating impeller shaft 102 away from the mounting frame 101. The driving bevel gear 111 is vertically arranged. The atomizing head 91 is fixedly connected to the driven bevel gear 112. The driven bevel gear 112 is located at the edge of the bottom of the atomizing head 91. The driven bevel gear 112 is horizontally arranged, and the driving bevel gear 111 is meshed with the driven bevel gear 112.

[0042] When the impeller shaft 102 rotates, the impeller shaft 102 drives the active bevel gear 111 to rotate, and the active bevel gear 111 drives the driven bevel gear 112 to rotate, and the driven bevel gear 112 drives the atomizing head 91 to rotate, so that the atomizing head 91 can spray water mist in all directions, further making the high-temperature exhaust gas contact with the sprayed water mist more fully and more thoroughly, so that the water mist can further and faster absorb the heat in the high-temperature exhaust gas.

[0043] Example 5

[0044] On the basis of Example 4, Figure 5 As shown, contact strips 12 are also included. A plurality of contact strips 12 are fixedly connected to both sides of the outer wall of each contact hollow plate 83, and each contact strip 12 is horizontally arranged.

[0045] When the high-temperature exhaust gas contacts the outer walls of the plurality of contact hollow plates 83, the high-temperature exhaust gas will contact the plurality of contact strips 12, thereby increasing the contact surface of the high-temperature exhaust gas and enabling the exhaust gas to be cooled more thoroughly.

[0046] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are only illustrative and not restrictive. Under the enlightenment of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present invention and the claims, which are all within the protection of the present invention.
