The embodiments of the present invention will be described in more detail below with reference to drawings and component symbols, so that those skilled in the art can implement them after studying this specification.

The invention provides a fossil fuel pollutant prevention system, which includes a control module, a pollutant generating device 20, a continuous washing device 30, a continuous aeration device 40, and a sewage treatment device 50.

The control module includes a first relay 11 (see FIGS. 2 and 3), a plurality of second relays 12, 13, 14 (see FIGS. 4 and 5) and a power supply touch 15 (see FIGS. 4 and 5) .

As shown in FIG. 1, the pollutant generating device 20 includes a combustion furnace 21, an air guide pipe 22 and a cooling module 23. The combustion furnace 21 encloses a combustion space 211 and defines an intake port 212, a fossil fuel input port 213, and an exhaust port 214. The intake port 212 communicates between the combustion space 211 and the external space, and is used to introduce external air into the combustion space 211. The fossil fuel input port 213 communicates between the combustion space 211 and the external space, and is used to input a fossil fuel (not shown) to the combustion space 211. The air duct 22 is connected between the exhaust port 214 and the cooling module 23.

The fossil fuel is combusted in the combustion space 211 and generates a high-temperature air pollutant 100. The high-temperature air pollutant 100 passes through the exhaust port 214 and the air guide pipe 22 in sequence, and then enters the cooling module 23. The cooling module 23 is used to reduce the temperature of the air pollutant 100.

More specifically, the air inlet 212 is opened on a side wall of the combustion furnace 21 and close to the bottom of the combustion furnace 21. The fossil fuel inlet 213 is opened on the side wall of the combustion furnace 21 and close to the bottom of the combustion furnace 21. The exhaust port 214 is opened at the top of the combustion furnace 21. The fossil fuels include natural resources such as coal, oil, and natural gas. The air pollutants 100 produced by burning fossil fuels include at least carbon dioxide (CO ₂ ), sulfur dioxide (SO ₂ ), and suspended particulate matter (Particulate Matter). During the combustion process, fossil fuel consumes a large amount of oxygen in the combustion space 211 and generates a large amount of high-temperature air pollutants 100. At the same time, an external air source continuously feeds into the combustion space 211 through the air inlet 212. According to the principle of thermal convection, the density of hot air is lower than that of cold air, so hot air rises and cold air falls. Therefore, the high-temperature air pollutant 100 rises to the exhaust port 214.

In a preferred embodiment, the cooling module 23 includes a cooling water tank 231, a water cooler 232, a cold water pipe 233, a hot water pipe 234, and a cooling pipe 235. The cooling water tank 231 is used for accommodating a cooling water. The cold water pipe 233 is connected between a water inlet at the bottom of a side wall of the cooling water tank 231 and a water outlet of the water cooler 232. The hot water pipe 234 is connected between a water outlet on the top of the side wall of the cooling water tank 231 and a water inlet of the water cooler 232. The cooling pipe 235 is located in the cooling water tank 231 and connected between the air guide pipe 22 and the continuous washing device 30. The high-temperature air pollutant 100 enters the continuous washing device 30 after sequentially passing through the air guide pipe 22 and the cooling pipe 235.

When the high-temperature air pollutant 100 passes through the cooling pipe 235, the high-temperature air pollutant 100 exchanges heat with the cooling water through the tube wall of the cooling pipe 235, thereby reducing the temperature of the air pollutant 100. Therefore, the temperature of the air pollutant 100 entering the continuous washing device 30 is greatly reduced.

According to the principle of thermal convection, the density of hot liquid is lower than that of cold liquid, so hot liquid rises and cold liquid falls. Therefore, the cooling water whose temperature rises rises and enters the water cooler 232 through the hot water pipe 234. The cooling water whose temperature has increased passes through the water cooler 232 for heat exchange, thereby reducing the temperature of the cooling water. The cooled cooling water further enters the cooling water tank 231 through the cold water pipe 233. In this way, the cooling water can be recycled repeatedly through the above mechanism, which is economical and environmentally friendly.

Preferably, a side wall of the cooling water tank 231 defines a first side hole and a second side hole, the first side hole is near the bottom of the cooling water tank 231, and the second side hole is near the top of the cooling water tank 231. One end of the cooling pipe 235 is connected to the air duct 22 through the first side hole, and the other end of the cooling pipe 235 is connected to the continuous washing device 30 through the second side hole. In other words, the cooling pipe 235 extends upward from the bottom of the cooling water tank 231 to the top of the cooling water tank 231. Since the water inlet of the cooling water tank 231 is located at the bottom of the side wall of the cooling water tank 231, the cooling water passing through the cold water pipe 233 first enters the bottom of the cooling water tank 231. In addition, according to the principle of thermal convection, the closer to the bottom of the cooling water tank 231, the lower the temperature of the cooling water; conversely, the closer to the top of the cooling water tank 231, the higher the temperature of the cooling water. Therefore, immediately after the high-temperature air pollutant 100 enters the cooling pipe 235, the tube wall of the cooling pipe 235 exchanges heat with the low-temperature cooling water at the bottom of the cooling water tank 231. Then, the high-temperature air pollutant 100 flows upward from the bottom of the cooling pipe 235 all the way to the top of the cooling pipe 235, and continuously performs heat exchange with the cooling water of the cooling water tank 231 through the wall of the cooling pipe 235. Thereby, the cooling module 23 can improve the heat exchange efficiency of the high-temperature air pollutant 100 and the cooling water, so that the temperature-lowering effect of the high-temperature air pollutant 100 is more significant.

Preferably, the cooling pipe 235 has a plurality of U-shaped bent portions, and the opening directions of the adjacent two U-shaped bent portions are opposite. In other words, the cooling pipe 235 is a continuous U-shaped bent pipe, and the path length of the cooling pipe 235 is greater than the linear distance between the first side hole and the second side hole. In this way, the meandering cooling pipe 235 can extend the time for the high-temperature air pollutant 100 and the cooling water to exchange heat, so that the effect of the high-temperature air pollutant 100 on cooling is more obvious.

As shown in FIGS. 2 and 3, the continuous washing device 30 includes a liquid storage tank 31, a connecting pipe module, a washing tank module, and a water injection module.

The first connecting pipe 321 is connected between the other end of the cooling pipe 235 and the top of the first washing tank 331. The two openings at the top of one of the second connecting pipes 322 are respectively connected to the bottom of the first washing tank 331 and the bottom of the second washing tank 332 close to the first washing tank 331. The two openings at the top of the other second connecting pipe 323 are respectively connected to the bottom of the second washing tank 333 in the middle and the bottom of the second washing tank 334 near the third washing tank 335. The bottoms of the two second connecting pipes 322 and 323 are located in the liquid storage tank 31. One of the third connecting pipes 324 is connected to the top of the second washing tank 332 near the first washing tank 331 and the top of the second washing tank 333 in the middle. Another third connecting pipe 324 is connected to the top of the second washing tank 334 and the top of the third washing tank 335 near the third washing tank 335. The bottom of the third washing tank 335 is connected to the top of the liquid storage tank 31. The water injection module includes a water storage tank 341, a water diversion main line 342, a plurality of water diversion auxiliary pipelines 343~347 and a water injection pump 348. The water storage tank 341 is used to store water 3411. The water diversion main line 342 is connected to the water storage tank 341. The water diversion auxiliary pipelines 343-347 are respectively connected between the water diversion main pipeline 342 and the first washing tank 331, the water diversion main pipeline 342 and the second washing tanks 332, 333, 334, and the water diversion main pipeline 342 and the first Between three washing tanks 335. The water injection pump 348 is provided on the water diversion main line 342, and is electrically connected to the first relay 11.

The air pollutant 100 passes through the first connecting pipe 321, the first washing tank 331, one of the second connecting pipes 322, the second washing tank 332 near the first washing tank 331, and one of the third connecting pipes 324 in the middle The second washing tank 333, another second connecting pipe 323, the second washing tank 334 close to the third washing tank 335, another third connecting pipe 324 and the third washing tank 335.

When the first relay 11 controls the water injection pump 348 to turn on, the water 3411 in the water storage tank 341 passes through the water diversion main line 342 and the water diversion auxiliary pipelines 343~347 in sequence, and then enters the first washing tank 331, the three second Washing tanks 332, 333, 334 and third washing tank 335. The water 3411 flows from the top to the bottom through the first washing tank 331, the three second washing tanks 332, 333, 334, the third washing tank 335, and the two second connecting pipes 322, 323 and enters the liquid storage tank 31. Part of the air pollutant 100 is dissolved in the water 3411 and chemically changes with the water 3411 to form a first pollutant solution 200, and enters the liquid storage tank 31. After passing through the third washing tank 335, the air pollutants 100 that are not dissolved in the water 3411 enter the liquid storage tank 31.

It is important that after the air pollutant 100 enters the first washing tank 331, the second washing tank 333 and the third washing tank 335 in the middle, from the first washing tank 331, the second washing tank 333 and the third washing in the middle The top of the tank 335 flows down to the bottom of the first washing tank 331, the second washing tank 333 in the middle, and the third washing tank 335. After the air pollutant 100 enters the second washing tank 332 close to the first washing tank 331 and the second washing tank 334 close to the third washing tank 335, the air pollutant 100 goes from the second washing tank 332 near the first washing tank 331 and close to the third washing The bottom of the second washing tank 334 of the tank 335 flows upward to the top of the second washing tank 332 near the first washing tank 331 and the second washing tank 334 near the third washing tank 335. In this way, calcium dioxide and sulfur dioxide in some air pollutants 100 can be fully dissolved in the water 3411 and chemically change with the water 3411 to form the first pollutant solution 200.

The chemical change of carbon dioxide dissolved in water produces carbonic acid. Sulphur dioxide is produced by chemical changes of sulfur dioxide dissolved in water. Therefore, the main components of the first pollutant solution 200 include carbonic acid and sulfurous acid.

It is worth mentioning that because the air pollutant 100 has been pre-cooled and cooled by the cooling module 23 before entering the continuous washing device 30, the solubility of carbon dioxide and sulfur dioxide in the air pollutant 100 dissolved in water is greatly improved, so the air In the process of performing continuous washing of the pollutant 100 by the continuous washing device 30, the content of carbon dioxide and sulfur dioxide dissolved in the water is greatly increased, effectively reducing the content of carbon dioxide and sulfur dioxide in the air pollutant 100 initially.

In addition, because the air pollutants 100 in the liquid storage tank 31 that are not dissolved in the lime water 4211 are continuously drawn out to the continuous aeration device 40, the pressure in the tank space of the liquid storage tank 31 drops, and the air pollutants 100 can continuously From the pollutant generating device 20 to the continuous aeration device 40 through the continuous washing device 30.
