The analog liquid level gauge protective cover 1.14 extends through the water level monitoring chamber 1.12 and the cooling water collection chamber 1.17.

A horizontal guide plate 1.15 and a vertical guide plate 1.18 are provided within the cooling water collection chamber 1.17. The top of the vertical guide plate 1.18 is connected to the top surface of the interior of the housing 1.2. The horizontal guide plate 1.15 is located below the vertical guide plate 1.18. The side of the horizontal guide plate 1.15 is fixedly connected to the vertical partition 1.11 of the water level monitoring chamber.

[0043] The exhaust gas purification unit cover 2 and the electronic control processing box 14 are respectively connected to the right side of the top surface of the box body 1. An exhaust gas back pressure sensor 11 is provided on the side of the exhaust gas purification unit cover 2. The exhaust gas purification unit cover 2 has a double-layer cooling cavity 2.1, which is connected in series with the cooling circulation system of the explosion-proof diesel engine to cool the exhaust gas purification unit cover 2 so that its surface temperature is lower than 150°C. The exhaust gas purification unit cover 2 is in a trumpet-shaped shape, which can reduce the back pressure generated by the exhaust gas passing through the purification carrier 3.

[0044] An analog level gauge 9 and exhaust flame arrester 13 are attached to the left side of the top surface of the casing 1.

[0046] A water-gas separation device 4 is provided inside the box body 1 and below the electronically controlled processing box 14. The water-gas separation device 4 has a fan blade structure in the middle, which can rotate with the exhaust gas. When water vapor passes through, the fan blade will throw the exhaust gas toward the surrounding wall, and the water splashes down the surrounding wall and falls back into the water washing chamber. The gas continues to float upward, thereby achieving the effect of water vapor separation.

[0047] Inside the box body 1, a variable motor fan 5 is provided below the fan air guide cover 1.19; a water check device 7 is provided on the front side of the bottom of the box body 1, and a silencer 6 is provided on the rear side of the bottom of the box body 1. One end of the water check device 7 is connected to the silencer 6 through an internal pipe 1.5, and the other end is connected to the second air disturbance cover 1.7.

[0048] The electronic control system is composed of the electronic control processing box 14, the electronic control shut-off valve 8, the analog liquid level meter 9, the exhaust temperature sensor 10, the exhaust back pressure sensor 11, and the variable motor fan 5, which monitors and adjusts the water level and exhaust temperature and monitors the status of the purification carrier 3.

[0049] Working process and principle:

[0050] The present invention is installed on the exhaust pipe of the explosion-proof diesel engine, and the exhaust pipe is connected to the flange of the purification unit gland 2, such as Figure 5 、 Figure 6As shown, the exhaust gas will first pass through the purification carrier 3 to absorb and chemically treat the particles, nitrogen oxides and carbon monoxide in the exhaust gas, and then pass through the silencer 6 along the internal pipe 1.5 for noise reduction treatment. At the same time, this step is partially immersed in the coolant, and the exhaust gas is wet-cooled. After passing through the check water device 7, it reaches the water washing chamber 1.8. Under the action of the first air scrambler 1.6 and the second air scrambler 1.7 in the water washing chamber 1.8, the exhaust gas comes into contact with the coolant and is discharged downward through the fan-shaped holes. After sufficient contact, the purpose of flame extinguishing and further dissolving soluble harmful gases is achieved. Under the action of exhaust pressure, the exhaust gas will carry some water and splash upward. At this time, the water washing chamber wave-breaking plate 1.4 blocks the water, and the exhaust gas can continue to move upward through the holes. After the separation action of the water-gas separation device 4, most of the water in the exhaust gas is separated and flows back to the bottom of the box 1. The exhaust gas is dispersed through the cooling pipe 1.20. If the exhaust port temperature measured by the exhaust temperature sensor 10 exceeds the calibration value, the variable motor fan 5 will work to continue to cool the exhaust gas by air cooling, and accelerate the condensation of water vapor while cooling. After the exhaust gas is ejected from the cooling pipe 1.20, it touches the vertical guide plate 1.18 and the direction of the exhaust gas is changed downward. At the same time, due to the rough structure of the surface of the vertical guide plate 1.18, the condensation of water vapor is further promoted to form water droplets, which flow back to the bottom of the box 1 with the downward driving force of the exhaust. The exhaust gas cooling and coolant recovery are completed through sufficient wet cooling, adaptive dry cooling and three-layer water-gas separation, achieving the effects of exhaust gas purification, flame extinguishing, cooling and low coolant consumption. After being guided again by the transverse guide plate 1.15, the exhaust gas will not be blown to the water surface again, but will be discharged into the environment through the exhaust flame arrester 13 and the exhaust cap 12.

[0051] In the present invention, the electronic control processing box 14, the electronic control shut-off valve 8, the analog liquid level meter 9, the exhaust temperature sensor 10, the exhaust back pressure sensor 11, and the variable motor fan 5 constitute an electronic control system to monitor and adjust the water level and exhaust temperature, and monitor the state of the purification carrier 3. Figure 7The analog level gauge 9 shown is calibrated to four positions, A, B, and D. When its float 9.1 reaches position B, the PLC in the electronic control processing box 14 causes the electronic shutoff valve 8 to open and refill water. When float 9.1 reaches position A, the electronic shutoff valve 8 closes, stopping refilling, ensuring that the coolant level remains between A and B during normal operation. When the water in the refill tank is depleted, float 9.1 passes position B and reaches position C. At this point, the electronic control processing box 14 transmits this information to the vehicle display and issues an alarm, prompting the driver to refill water. When float 9.1 continues to drop to position D, the electronic control processing box 14 outputs a signal to shut down the vehicle for protection. This intelligent refill mechanism avoids the uncontrollable and unreliable nature of simple mechanical refilling. Exhaust temperature sensor 10 monitors the exhaust outlet temperature, and the electronic control processing box 14 controls the on / off and speed of the variable motor fan 5, further improving the ability of simple wet cooling in high or low temperature environments, ensuring that exhaust temperature remains within the specified range under various conditions. The exhaust back pressure sensor detects the back pressure of the exhaust gas at the outlet of the exhaust gas purification unit gland 2, and feeds back the blockage of the purification carrier 3 through the electronic control processing box 14, thus ensuring the normal operation of the engine.

[0052] The analog level gauge protective cover 1.14 ensures that the float 9.1 of the analog level gauge 9 is not affected by the flow of coolant.

[0053] The inspection cover plate 15 of the water-gas separator, the inspection cover plate 17 of the water check device, and the inspection cover plate 20 of the muffler can be used to inspect and replace the corresponding components.

[0054] The front air inlet cover 16, the rear air inlet cover 18 and the air outlet 19 protect the variable motor fan 5 and prevent foreign objects from damaging it.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
