Description

Technical Field

[0001] The invention relates to the technical field of radiators, and in particular to an explosion-proof diesel engine exhaust radiator and a system thereof. Background Art

[0002] When working in a mine, explosion-proof diesel engines will emit a large amount of high-temperature exhaust gas (500-660℃), which is mixed with sparks. The high temperature and sparks will detonate underground gas, posing a major safety hazard. Generally, an exhaust gas treatment box is used at the construction site to cool the high-temperature exhaust gas (to below 70℃), reduce dust, and eliminate sparks before it can be discharged.

[0003] During the exhaust gas treatment box's cooling process, the high-temperature exhaust gas will continuously vaporize the cooling water in the box. When the exhaust gas treatment box's water level is insufficient, water is added to the exhaust gas treatment box through the water supply tank. Due to the space for the entire explosion-proof vehicle layout, the exhaust gas treatment box and the water supply tank have limited capacity. When the water resources in the water supply tank are exhausted, the high-temperature exhaust gas cannot be cooled any further. At this time, the explosion-proof diesel engine cannot continue to work normally, resulting in a significant limitation in the working time and mileage of the explosion-proof diesel engine. Summary of the invention

[0004] The technical problem to be solved by the present invention is: how to reduce or lower the cooling water consumption of a traditional water-cooled-evaporative wet exhaust gas treatment box of an explosion-proof diesel engine and increase the working time and mileage of the explosion-proof diesel engine.

[0005] The technical solution of the present invention to solve the above technical problems is as follows:

[0006] The present invention provides an explosion-proof diesel engine exhaust radiator, comprising a base plate and a shell. The base plate is fixed to one side of the shell. Blades are arranged on one side of the base plate, and the blades are located in the shell. The blades are arranged in a spiral shape to form a vortex flue. The interior of the blades is hollow and forms a vortex water channel. An air inlet pipe is arranged in the middle of the other side of the base plate, and one end of the air inlet pipe passes through the base plate and is provided with an air outlet. The shell is provided with an air outlet pipe, and the air outlet pipe and the air outlet are respectively connected to the vortex flue. A liquid inlet and a liquid outlet are also provided on the base plate, and the liquid inlet and the liquid outlet are respectively connected to the vortex water channel.

[0007] The beneficial effects of the present invention are:

[0008] According to the present invention, the coolant flows in the vortex water channel inside the blades, and the high-temperature exhaust gas flows in the vortex flue outside the blades, so that the heat exchange between the coolant and the high-temperature exhaust gas is realized, and the temperature of the high-temperature exhaust gas is reduced; and the coolant in the vortex water channel can be recycled, and the coolant consumption is small; the consumption of cooling water in the original water-cooled-evaporative wet exhaust gas treatment box is effectively reduced, and the working time and mileage of the explosion-proof diesel engine are greatly increased. In addition, the high-temperature exhaust gas flows from the inside to the outside along the vortex flue, and the high-temperature exhaust gas only contacts the inner wall of the shell when the temperature drops to the lowest, so that the temperature of the outer wall of the shell is low and the explosion-proof performance is good.

[0018] Furthermore, the plurality of blades are evenly distributed along the circumference of the air inlet pipe, and the air outlet holes are arranged on the side wall of the air inlet pipe and evenly distributed along the circumference of the air inlet pipe.

[0020] Furthermore, one end of the air inlet pipe is closed and provided with an airflow guide cone, and the small end of the airflow guide cone faces the base plate.

DETAILED DESCRIPTION

[0036] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0037] The present invention refers to Figure 1-6 .

[0038] like Figure 1-5 As shown:

[0039] The present invention provides an explosion-proof diesel engine exhaust radiator, comprising a base plate 1 and a shell 2. The base plate 1 is fixed to one side of the shell 2. Blades 3 are provided on one side of the base plate 1. The blades 3 are located in the shell 2. The blades 3 are arranged in a spiral shape to form a vortex flue 4. The inside of the blades 3 is hollow and forms a vortex waterway 5. An air inlet pipe 6 is provided in the middle of the other side of the base plate 1. One end of the air inlet pipe 6 passes through the base plate 1 and is provided with an air outlet hole 7. An air outlet pipe 8 is provided on the shell 2.

[0042] During operation, the coolant enters the vortex water channel 5 inside the blade 3 from the liquid inlet 9, circulates inside the blade 3 and is discharged through the liquid outlet 10. The temperature of the coolant rises, and the coolant with the increased temperature is transported to the heat dissipation device for cooling and recycling. At the same time, the high-temperature exhaust gas of the explosion-proof diesel engine enters from the air intake pipe 6, flows into the vortex flue 4 outside the blade 3 through the air outlet 7 on the air intake pipe 6, and is discharged through the air outlet pipe 8. There is no direct contact between the coolant and the high-temperature exhaust gas. Heat exchange is achieved through the side wall of the blade 3 to cool the high-temperature exhaust gas. The cooled exhaust gas is then transported to the exhaust gas treatment box, treated in the exhaust gas treatment box and discharged, reducing the amount of coolant vaporization in the exhaust gas treatment box.

[0043] According to the present invention, the coolant flows in the vortex water channel 5 inside the blade 3, and the high-temperature exhaust gas flows in the vortex flue 4 outside the blade 3, so that the heat exchange between the coolant and the high-temperature exhaust gas is realized, and the temperature of the high-temperature exhaust gas is reduced; and the coolant in the vortex water channel 5 can be recycled, and the coolant consumption is small; the consumption of cooling water in the original water-cooled-evaporative wet exhaust gas treatment box is effectively reduced, and the working time and mileage of the explosion-proof diesel engine are greatly increased. In addition, the high-temperature exhaust gas flows from the inside to the outside along the vortex flue 4, and the high-temperature exhaust gas only contacts the inner wall of the shell 2 when the temperature drops to the lowest, so that the temperature of the outer wall of the shell 2 is low, and the explosion-proof performance is good.
