Description

Fossil fuel pollutant control system

Technical Field

The invention relates to a fossil fuel pollutant control system, in particular to a fossil fuel pollutant control system which is used for providing air pollutants generated by burning fossil fuels to be sequentially subjected to cooling, washing, aeration and other procedures.

Background

Fossil fuel (fossil fuel) is a hydrocarbon or its derivative, and includes natural resources such as coal, oil, and natural gas. Fossil fuels are a very important energy source, and bring countless benefits to human beings, such as thermal power generation.

However, burning fossil fuels produces air pollutants such as carbon dioxide (CO2), sulfur dioxide (SO2), and suspended particulates (Particulate Matter). The air pollutants and the water and the air are mixed and then fall on the ground to form acid rain, which has the corrosion effect on the natural environment and the buildings.

A common apparatus for removing air pollutants generated by burning fossil fuels includes: nitrogen oxide suppression and reduction equipment, boiler exhaust gas temperature suppression and reduction equipment, particulate matter collection equipment, desulfurization equipment, dust falling reduction equipment and the like. Although there are related devices for removing carbon dioxide (CO2), sulfur dioxide (SO2) and suspended Particulate Matter (Particulate Matter), these devices are directed to spraying water or lime water against high temperature air pollutants. The higher the temperature of the air pollutants, the poorer the solubility of carbon dioxide and sulfur dioxide in water or lime water, and thus the less effective the existing equipment is in removing carbon dioxide, sulfur dioxide and suspended particulate matter.

The embodiments of the present invention will be described in more detail with reference to the drawings and the reference numerals, so that those skilled in the art can implement the embodiments after reading the description.

Referring to fig. 1 to 6, fig. 1 is a schematic view of a pollutant generating device 20 according to the present invention; FIG. 2 is a schematic view of the continuous scrubbing apparatus 30 of the present invention wherein the level of the first contaminant solution 200 is at a high level H2; FIG. 3 is a schematic view of the continuous scrubbing apparatus 30 of the present invention wherein the level of the first contaminant solution 200 is at a low level L2; FIG. 4 is a schematic view of the continuous aeration apparatus 40 of the present invention wherein the level of the second contaminant solution 201 is at a high level H1; FIG. 5 is a schematic view of continuous aeration apparatus 40 of the present invention wherein the level of second contaminant solution 201 is at a low level L1; fig. 6 is a schematic view of a sewage treatment apparatus 50 of the present invention. The invention provides a fossil fuel pollutant prevention and treatment system, which comprises 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 fig. 2 and 3), a plurality of second relays 12, 13, 14 (see fig. 4 and 5), and a power supply touch controller 15 (see fig. 4 and 5).

As shown in fig. 1, the pollutant generating device 20 comprises a combustion furnace 21, an air duct 22 and a cooling module 23. The burner 21 encloses a combustion space 211 and is provided with an inlet 212, a fossil fuel inlet 213 and an outlet 214. The intake port 212 communicates between the combustion space 211 and an external space, and serves to introduce external air into the combustion space 211. The fossil fuel input port 213 is connected between the combustion space 211 and the external space, and is used for inputting a fossil fuel (not shown) into 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 to generate a high temperature air pollutant 100, and the high temperature air pollutant 100 enters the cooling module 23 after passing through the exhaust port 214 and the air duct 22. The cooling module 23 is used to reduce the temperature of the air pollutants 100.

More specifically, the inlet 212 opens to a side wall of the burner 21 and is located near the bottom of the burner 21. The fossil fuel input port 213 opens at a side wall of the furnace 21 and is located near the bottom of the furnace 21. An exhaust port 214 opens at the top of the burner 21. The fossil fuel includes coal, petroleum, natural gas and other natural resources, and the air pollutant 100 generated by burning the fossil fuel at least comprises carbon dioxide (CO2), sulfur dioxide (SO2) and suspended particulate matter (particulate matter). The fossil fuel consumes a large amount of oxygen in the combustion space 211 during combustion and generates a large amount of high-temperature air pollutants 100, while external air is continuously supplied into the combustion space 211 through the air inlet 212. According to the heat convection principle, the density of hot air is lower than that of cold air, so that the hot air rises and the cold air falls. Therefore, the high temperature air pollutants 100 rise to the exhaust port 214.

In the 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 containing a cooling water. The cold water pipe 233 is connected between an inlet at the bottom of a side wall of the cooling water tank 231 and an outlet of the water cooler 232. The hot water pipe 234 is connected between an outlet at the top of the sidewall of the cooling water tank 231 and an inlet of the water cooler 232. A cooling line 235 is located in the cooling water tank 231 and connected between the air duct 22 and the continuous washing apparatus 30. The air pollutants 100 with high temperature enter the continuous washing device 30 after passing through the air duct 22 and the cooling pipeline 235 in sequence.

During the process of the high temperature air pollutants 100 passing through the cooling pipe 235, the high temperature air pollutants 100 exchange heat with the cooling water through the pipe wall of the cooling pipe 235, thereby reducing the temperature of the air pollutants 100. Therefore, the temperature of the air pollutants 100 entering the continuous washing apparatus 30 is greatly reduced.

According to the principle of thermal convection, hot liquid has a lower density than cold liquid, so that hot liquid rises and cold liquid falls. Thus, the cooling water having an increased temperature rises and enters the water cooler 232 through the hot water pipe 234. The cooling water having the increased temperature is heat-exchanged through the water cooler 232, 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. Therefore, the cooling water can be repeatedly recycled through the mechanism, and the cooling water is economical, practical and environment-friendly.

Preferably, a side wall of the cooling water tank 231 is provided with a first side hole and a second side hole, the first side hole is close to the bottom of the cooling water tank 231, and the second side hole is close to the top of the cooling water tank 231. One end of the cooling pipeline 235 is connected to the air duct 22 via a first side hole, and the other end of the cooling pipeline 235 is connected to the continuous washing device 30 via a second side hole. In other words, the cooling pipe 235 extends 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. Further, according to the heat convection principle, 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, the high-temperature air pollutants 100 are heat exchanged with the low-temperature cooling water at the bottom of the cooling water tank 231 through the wall of the cooling pipeline 235 immediately after entering the cooling pipeline 235. Then, the high temperature air pollutants 100 flow from the bottom of the cooling pipeline 235 all the way up to the top of the cooling pipeline 235, and continuously exchange heat with the cooling water in the cooling water tank 231 through the wall of the cooling pipeline 235. Therefore, the cooling module 23 can improve the heat exchange efficiency between the high-temperature air pollutants 100 and the cooling water, so that the cooling effect of the high-temperature air pollutants 100 is more remarkable.

Preferably, the cooling pipe 235 has a plurality of U-shaped bent portions, and the openings of two adjacent 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. Therefore, the winding cooling pipeline 235 can prolong the time of heat exchange between the high-temperature air pollutants 100 and the cooling water, so that the effect of cooling the high-temperature air pollutants 100 is more obvious.

As shown in FIGS. 2 and 3, the continuous washing apparatus 30 includes a liquid tank 31, a connecting pipe module, a washing tank module and a water injection module. The connecting pipe module includes a first connecting pipe 321, two second connecting

pipes

322, 323, and two third connecting

pipes

324, 325. The washing tank module includes a first washing tank 331, three

second washing tanks

332, 333, 334 and a third washing tank 335. The first connection pipe 321 is connected between the other end of the cooling line 235 and the top of the first washtub 331. Wherein two openings at the top of a second connecting pipe 322 are respectively connected to the bottom of the first washing tank 331 and the bottom of the second washing tank 332 adjacent to the first washing tank 331. The two openings at the top of the other second connection pipe 323 are connected to the bottom of the second washtub 333 positioned in the middle and the bottom of the second washtub 334 adjacent to the third washtub 335, respectively. The bottoms of the

second connection pipes

322 and 323 are located in the sump 31. Wherein a third connection pipe 324 is connected to the top of the second washtub 332 adjacent to the first washtub 331 and the top of the second washtub 333 in the middle. Another third connection pipe 324 is connected to the top of the second washtub 334 and the top of the third washtub 335 near the third washtub 335. The bottom of the third washing tank 335 is connected to the top of the sump 31. The water injection module includes a water tank 341, a main water conduit 342, a plurality of auxiliary water conduits 343-347, and a water injection pump 348. The water storage tank 341 is used for storing water 4211. The main water conduit 342 is connected to the reservoir 341. The water diversion sub-pipes 343-347 are connected between the water diversion main pipe 342 and the first washing tank 331, between the water diversion main pipe 342 and the

second washing tanks

332, 333, 334, and between the water diversion main pipe 342 and the third washing tank 335, respectively. The water filling pump 348 is disposed on the main water conduit 342 and electrically connected to the first relay 11.

The contaminants 100 sequentially pass through the first connection pipe 321, the first washtub 331, one of the second connection pipes 322, the second washtub 332 adjacent to the first washtub 331, one of the third connection pipes 324, the second washtub 333 located in the middle, the other second connection pipe 323, the second washtub 334 adjacent to the third washtub 335, the other third connection pipe 324, and the third washtub 335.

When the first relay 11 controls the water injection pump 348 to be turned on, the water 3411 in the water storage tank 341 sequentially passes through the water main pipe 342 and the water auxiliary pipes 343 to 347, and then enters the first washing tank 331, the

third washing tanks

332, 333 and 334 and the third washing tank 335. Water 3411 flows through first washing tank 331, third

second washing tanks

332, 333, 334, third washing tank 335, and

second connection pipes

322, 323 from the top to the bottom into liquid sump 31. A portion of the air contaminant 100 dissolves in the water 3411 and chemically changes with the water 3411 to form a first contaminant solution 200, and enters the liquid sump 31. The air contaminant 100 not dissolved in the water 3411 enters the sump 31 after passing through the third washing tank 335.

It is important that the air pollutants 100, after entering the first washtub 331, the second washtub 333 and the third washtub 335 in the middle, flow downward from the top of the first washtub 331, the second washtub 333 and the third washtub 335 in the middle to the bottom of the first washtub 331, the second washtub 333 and the third washtub 335 in the middle. After the air pollutants 100 enter the second washing tank 332 adjacent to the first washing tank 331 and the second washing tank 334 adjacent to the third washing tank 335, the air pollutants flow upward from the bottom of the second washing tank 332 adjacent to the first washing tank 331 and the second washing tank 334 adjacent to the third washing tank 335 to the top of the second washing tank 332 adjacent to the first washing tank 331 and the second washing tank 334 adjacent to the third washing tank 335. Thereby, part of the calcium dioxide and sulfur dioxide in the air pollutant 100 can be sufficiently dissolved in the water 3411 and chemically changed with the water 3411 to form the first pollutant solution 200.

The chemical change of carbon dioxide dissolved in water produces carbonic acid. The chemical change of the dissolution of sulfur dioxide in water produces sulfurous acid. Thus, the main components of the first contaminant solution 200 include carbonic acid and sulfurous acid.

It should be noted that, because the air pollutants 100 are cooled by the cooling module 23 before entering the continuous washing device 30, the solubility of the carbon dioxide and the sulfur dioxide dissolved in the water in the air pollutants 100 is greatly improved, so that the content of the carbon dioxide and the sulfur dioxide dissolved in the water in the process of performing the continuous washing of the continuous washing device 30 of the air pollutants 100 is greatly increased, and the content of the carbon dioxide and the sulfur dioxide in the air pollutants 100 is effectively and primarily reduced.

As shown in fig. 2 and 3, in the preferred embodiment, each of the water guide auxiliary pipes 343-347 includes a

vertical pipe

3431, 3441, 3451, 3461, 3471 and a plurality of

horizontal pipes

3432, 3442, 3452, 3462, 3472. The

vertical pipes

3431, 3441, 3451, 3461, 3471 are connected to the water main 342. The

horizontal pipes

3432, 3442, 3452, 3462 and 3472 are connected to the

vertical pipes

3431, 3441, 3451, 3461 and 3471 respectively and have two

water outlets

3433, 3443, 3453, 3463 and 3473 respectively at the bottom. The horizontal pipes 3432 of one of the water introducing sub-pipes 343 extend transversely into the first wash tank 331 and are longitudinally spaced from each other. Wherein the

horizontal pipes

3442, 3452, 3462 of the three

lead water sub-pipes

344, 345, 346 extend transversely into the three

second washtubs

332, 333, 334, respectively, and are longitudinally spaced from each other. The horizontal pipes 3472 of one of the water introducing sub-pipes 347 transversely extend into the third wash tank 335 and are longitudinally spaced from each other. In other words, the

horizontal pipes

third washing tanks

332, 333, 334 and the third washing tank 335. When the first relay 11 controls the water injection pump 348 to be turned on, the water 3411 in the water storage tank 341 passes through the main water conduit 342 and the auxiliary water conduits 343-347 in sequence, and then is sprayed downwards from the

water spraying ports

3433, 3443, 3453, 3463, 3473, so that water is sprayed downwards from different vertical positions of the first washing tank 331, the

third washing tanks

332, 333, 334 and the third washing tank 335, thereby achieving the purpose of multi-stage water spraying. Therefore, the probability of the air pollutant 100 contacting the water 3411 is greatly increased, so that the content of carbon dioxide and sulfur dioxide dissolved in the water is significantly increased, and the content of carbon dioxide and sulfur dioxide in the air pollutant 100 is significantly reduced.

As shown in fig. 4 and 5, the continuous aeration device 40 includes an aeration tank module, a lime water injection module and a gas guiding module. The aeration tank module includes a first aeration tank 411, a second aeration tank 412 and a third aeration tank 413.

4291, 4292 and 4293 are used for sensing the liquid level heights of the lime water 4211 in the first aeration tank 411, the second aeration tank 412 and the third aeration tank 413 respectively. The gas guiding module includes a first vent pipe 431,

second vent pipes

second aeration pipes

432 and 433 are connected between the top of the first aeration tank 411 and the bottom of the second aeration tank 412 and between the top of the second aeration tank 412 and the bottom of the third aeration tank 413, respectively. The third aeration pipe 434 is connected to the top of the third aeration tank 413. The

exhaust fans

435, 436, 437 are respectively disposed on the first air pipe 431 and the

second air pipes

432, 433, and are electrically connected to the power touch controller 15.

As shown in fig. 4, when the first

liquid level sensors

4291, 4292, 4293 sense that the liquid levels of the lime water 4211 of the first aeration tank 411, the second aeration tank 412 and the third aeration tank 413 are at the high liquid level H1, the first

liquid level sensors

4291, 4292, 4293 generate first high liquid level signals, respectively, and transmit the first high liquid level signals to the second relays 12, 13, 14, respectively. The second relays 12, 13, and 14 control the lime water injection pumps 426, 427, and 428 to be turned off according to the first high liquid level signals, respectively, so as to stop injecting the lime water 4211 into the first aeration tank 411, the second aeration tank 412, and the third aeration tank 413.

As shown in fig. 5, when the first

liquid level sensors

4291, 4292, 4293 sense that the liquid levels of the lime water 4211 of the first aeration tank 411, the second aeration tank 412 and the third aeration tank 413 are at the low liquid level L1, the first

liquid level sensors

4291, 4292, 4293 generate first low liquid level signals, respectively, and transmit the first low liquid level signals to the second relays 12, 13, 14, respectively. The second relays 12, 13, 14 control the limewater pumps 426, 427, 428 to turn on according to the first low level signals. The lime water 4211 in the lime water tank 421 passes through the main lime water injection pipeline 422 and the secondary lime

water injection pipelines

423, 424 and 425 in sequence, and then enters the first aeration tank 411, the second aeration tank 412 and the third aeration tank 413.

As shown in fig. 4 and 5, when the power touch controller 15 controls the

suction fans

435, 436, 437 to be turned on, the air pollutants 100 in the liquid storage tank 31, which are not dissolved in the water 3411, sequentially pass through the first air pipe 431, the first aeration tank 411, one of the second air pipes 432, the second aeration tank 412, the other second air pipe 433, and the third aeration tank 413. A portion of air pollutants 100 dissolves in lime water 4211 and chemically changes to form a second pollutant solution 201. The air contaminant 100 not dissolved in the lime water 4211 enters the external space through the third vent pipe 434. In addition, since the air contaminant 100 in the liquid sump 31, which is not dissolved in the lime water 4211, is continuously pumped out to the continuous aeration apparatus 40, the pressure of the space in the liquid sump 31 drops, and the air contaminant 100 can be continuously introduced from the contaminant generating apparatus 20 into the continuous aeration apparatus 40 through the continuous washing apparatus 30.

It is important that the air pollutants 100, after entering the first, second and

third aeration tanks

411, 412 and 413, flow upward through the lime water 4211 in the form of air bubbles 101 from the bottoms of the first, second and

third aeration tanks

411, 412 and 413 to the tops of the first, second and

third aeration tanks

411, 412 and 413. Thereby, the carbon dioxide and the sulfur dioxide in the air pollutant 100 can be sufficiently dissolved in the lime water and chemically changed with the lime water to form the second pollutant solution 201.

The chemical change of carbon dioxide dissolved in lime water produces calcium carbonate and water. The chemical change of the sulfur dioxide dissolved in the lime water produces calcium sulfite and water. Thus, the composition of the second contaminant solution 201 mainly includes calcium carbonate, calcium sulfite, and water.

It should be noted that, because the air pollutants 100 are cooled by the cooling module 23 before entering the continuous washing device 30, the solubility of the carbon dioxide and the sulfur dioxide dissolved in the lime water 4211 in the air pollutants 100 is greatly improved, during the continuous aeration process of the continuous aeration device 40, the content of the carbon dioxide and the sulfur dioxide dissolved in the lime water 4211 of the air pollutants 100 is greatly increased, and the content of the carbon dioxide and the sulfur dioxide in the air pollutants 100 is effectively further reduced. The air pollutants 100 entering the external space, which are not dissolved in the lime water 4211, are substantially clean with almost no carbon dioxide and sulfur dioxide.

As shown in fig. 4 and 5, in the preferred embodiment, the gas guiding module further includes a plurality of

aeration pipes

4381, 4382, 4383, wherein the

aeration pipes

4381, 4382, 4383 are respectively disposed in the first aeration tank 411, the second aeration tank 412, and the third aeration tank 413, respectively connected to the first aeration pipe 431 and the

second aeration pipes

432, 433, and opened with a plurality of air holes (not shown). After passing through the air holes of the

aeration pipes

4381, 4382, 4383, the air pollutants 100 enter the first, second, and

third aeration tanks

411, 412, and 413, and flow upward through the lime water 4211 from the bottoms of the first, second, and

third aeration tanks

411, 412, and 413 to the tops of the first, second, and

third aeration tanks

411, 412, and 413 in the form of air bubbles 101. Thereby, the

aeration pipes

4381, 4382, 4383 can increase the amount of the air contaminant 100 entering the first, second, and

third aeration tanks

411, 412, and 413 per unit time.

Preferably, the

aeration pipes

4381, 4382 and 4383 are ring-shaped and coaxial with the first aeration tank 411, the second aeration tank 412 and the third aeration tank 413, respectively, and the air holes of the

aeration pipes

4381, 4382 and 4383 are opened on the top surfaces of the

aeration pipes

4381, 4382 and 4383. This technical feature can further increase the amount of the air contaminant 100 entering the first, second and

third aeration tanks

411, 412 and 413 per unit time.

As shown in fig. 2, when the second liquid level sensor 523 senses that the liquid level of the first contaminant solution 200 in the tank 31 is at the high level H2, the second liquid level sensor 523 generates a second high level signal and transmits the second high level signal to the first relay 11. The first relay 11 controls the water pump 522 to turn on according to the second high level signal, and the first contaminant solution 200 in the liquid storage tank 31 enters the waste liquid tank 514 of the sedimentation tank 511 after sequentially passing through the drainage pipe 521 and the sedimentation pipe 512. At least the space within the sump 31 maintained above the high level H2 is left for air contaminants 100 that are not dissolved in the water 3411.

As shown in fig. 3, when the second liquid level sensor 523 senses that the level of the first contaminant solution 200 in the tank 31 is at the low level L2, the second liquid level sensor 523 generates a second low level signal and transmits the second low level signal to the first relay 11. The first relay 11 controls the pump 522 to turn off according to the second low level signal, thereby stopping pumping the first contaminant solution 200 out of the tank 31. At least the bottoms of the

second connection pipes

322 and 323 are maintained below the low level L2 in the sump 31 so that the bottoms of the

second connection pipes

auxiliary piping

532, 533, 534, the main piping 531 and the settling pipe 512, and then enters the waste liquid tank 514 of the settling tank 511.

First contaminant solution 200 and second contaminant solution 201 are combined in a waste tank 514 of settling tank 511 to form a third contaminant solution 202. After the third contaminant solution 202 is allowed to stand for a period of time, the sludge 203 in the third contaminant solution 202 passes down through the plurality of holes of the row 513 of sludge holes into the sludge tank 515, and the remaining third contaminant solution 202 remains in the waste tank 514. The main components of the sludge 202 include calcium carbonate, calcium sulfite, and suspended particulates. The main components of the remaining third contaminant solution 202 include carbonic acid, sulfurous acid, and water.

When the control module controls the sludge pump 518 to be turned on, the sludge 203 enters a sludge collecting part (not shown) through the sludge discharge pipe 517. The remaining third contaminant solution 202 in the waste liquid tank 514 may be introduced into a waste liquid collecting portion (not shown) through the drain pipe 516. The user may determine to increase or decrease the concentration of the lime water 4211 in the lime water tank 421 by detecting the ph of the remaining third contaminant solution 202 passing through the drain 516. When the ph of the remaining third contaminant solution 202 is greater than 7, the concentration of the lime water 4211 in the lime water tank 421 must be reduced. When the ph of the remaining third contaminant solution 202 is below 7, the concentration of the lime water must be increased.
