Description

Smoke cleaning equipment

This creation relates to an air cleaning device, and more particularly to an air cleaning device for a chimney.

In industrial waste gas pollution, part of the exhaust gas is greenhouse gas, which is the culprit of global warming. In the 2014 UN Climate Summit, countries around the world signed a Paris agreement in an attempt to slow the global warming trend, with the goal of keeping the temperature increase within 2 degrees Celsius compared to the pre-industrial period. For the Paris Agreement, the targets of the world's 2 degrees Celsius are scheduled to be reached within 14 years, showing the incomprehensible greenhouse gases.

Another type of air pollution is suspended particles, which refers to solid particles or droplets suspended in the air. Suspended particles can stay in the atmosphere for a long time and enter the body with the breath. Suspended particles with a diameter of less than or equal to 2.5 microns are called fine suspended particles, ie PM2.5, and also adsorb harmful substances such as heavy metals, which have a great impact on human health. Of course, in addition to the impact of human health, air pollution can also cause damage to various animals and plants. Therefore, the damage caused by industrial waste gas is not only comprehensive, but the scope of the impact is even more difficult to estimate.

In view of this, providing a better improvement solution is an urgent problem to be solved in the industry.

The main purpose of the present invention is to provide a soot cleaning device that can be placed at the exhaust port of an industrial chimney to purify industrial exhaust gas.

In order to achieve the above object, the present invention provides a smoke cleaning device having: a cooling chamber connected to the exhaust port of the chimney; and a filtering chamber communicating with the cooling chamber; wherein the exhaust gas is finally Discharged from the filtration chamber.

Therefore, the advantage of this creation is that the industrial waste gas can be cooled by the cooling chamber and filtered by the filtration chamber, so that the harmful substances in the exhaust gas are greatly reduced, so that after being discharged to the atmosphere, the environment is not burdened and can be internationally specification.

Please refer to Figure 1 and Figure 2. The present invention proposes a smoke cleaning device for a chimney, which is disposed at an exhaust port of a chimney A for filtering exhaust gas discharged from the chimney A. For example, it can be used for a chimney A having a diameter of 30 cm or more, for example, for a chimney A having a diameter of 60 cm to 100 cm. The smoke cleaning device has a cooling space 1, a normal temperature space 2, a supporting structure 3 and a water supply system 4, and the cooling space 1 and the normal temperature space 2 are independent of each other, and are connected by only one channel. The occupied area of the cooling space 1 and the normal temperature space 2 may be two adjacent rectangles of 7 meters by 7 meters, respectively, and the height thereof may be more than 32 meters.

In the first embodiment, the cooling space 1 has a cooling chamber 11 and a mixing chamber 12. The cooling chamber 11 is disposed above the chimney A, communicates with the exhaust port of the chimney A, and absorbs exhaust gas discharged from the chimney A.

In the present embodiment, the water supply system 4 has a first water storage tank 41 located above the cooling chamber 11 and the mixing chamber 12. In the present embodiment, the working fluid is water, which can be driven from the ground to the first water storage tank 41 through a pump. The cooling chamber 11 has a cooling tube 111 disposed vertically, and specifically, the cooling tube 111 is extended from the top to the bottom by the inside of the cooling chamber 11. Therefore, the water in the cooling pipe 111 flows downward from above. The upper end of the cooling pipe 111 communicates with the first water storage tank 41 to supply cooling pipe 111 water to cool the exhaust gas.

The inner wall of the cooling chamber 11 is provided with a heat insulating layer 13 which can reduce the heat transfer from the factory exhaust gas to the outside.

One end of the mixing chamber 12 communicates with the cooling chamber 11 to receive the exhaust gas cooled by the first stage of the cooling chamber 11, and the other end communicates with the filtering chamber 12. The mixing chamber 12 has at least one mixing compartment 120 for mixing air at ambient temperature for mixing to perform a second stage of cooling. The mixing chamber 12 can have a single mixing compartment 120 with one end in communication with the cooling chamber 11 and the other end in communication with the filtration chamber 12. However, in the present embodiment, there are a plurality of mixing compartments 120, and each mixing compartment 120 is in communication with each other.

The chimney smoke cleaning device further has a plurality of mixing and pumping units 121 disposed between the two mixing compartments 120. Specifically, each of the mixing compartments 120 is vertically arranged vertically downward and connected in series with each other, and two adjacent mixing compartments 120 are communicated through at least one mixing and extracting unit 121, and the mixing and exhausting unit 121 will be located above the mixing. The gas in the compartment 120 is drawn to the mixing compartment 120 that is connected below. In other words, the mixing pumping unit 121 transmits the exhaust gas vertically downward.

The side wall of each mixing compartment 120 has at least one mixing air inlet 122, and the normal temperature air is driven into the mixing compartment 120 through the mixing air inlet 122 to dilute the high temperature exhaust gas to achieve the purpose of cooling in the second stage. For example, an air compressor (not shown) may be used to connect the mixing air inlet 122 to drive air into the mixing compartment 120. At least one mixing and extracting unit 121 between the mixing compartments 120 in this embodiment is a two-mixing and pumping unit 121, but the number is not limited thereto.

The mixing compartment 120 at one end thereof is openly and horizontally juxtaposed to the cooling chamber 11, and the inner wall surface of the mixing compartment 120 also has a heat insulating layer 13. The smoke cleaning device of the chimney further has at least one connected suction unit 14 which is located between the cooling space 1 and the normal temperature space 2. Therefore, in the present embodiment, the mixing compartment 120 at the other end communicates with the room temperature space 2 through the communication air suction unit 14. In the present embodiment, each of the mixing compartments 120 is vertically connected in series, so that the cooling compartment 11 is connected to the uppermost mixing compartment 120, and the normal temperature space 2 is the lowermost mixing compartment 120. In other embodiments, the serial connection manner of each mixing compartment 120 may also be changed depending on the design of the plant, for example, horizontally.

The room temperature space 2 has a neutralization chamber 21 and a filtration chamber 22. The neutralization chamber 21 communicates with the mixing compartment 120 at the other end through the communication suction unit 14. In other words, the lowermost mixing compartment 120 in this embodiment is in communication with the filtration chamber 22 through the neutralization chamber 21. In the present embodiment, the neutralization chamber 21 is located on one side of the lowermost mixing compartment 120 and juxtaposed horizontally, in other words, the pumping direction of the communication pumping unit 14 is horizontal. However, in other embodiments, the neutralization chamber 21 may also be located below the lowermost mixing compartment 120, while the pumping direction of the communication pumping unit 14 is vertically downward. The neutralization chamber 21 has at least one neutralization inlet 211. The present invention drives the neutralizing gas into the neutralization chamber 21 through the neutral inlet 211 to detoxify and neutralize the exhaust gas. The neutralizing gas can be oxygen, ozone or pure oxygen.

In the present embodiment, the filtration chamber 22 is disposed above and in communication with the neutralization chamber 21, so that the filtration chamber 22 communicates with the cooling chamber 11 through the neutralization chamber 21 and the mixing chamber 12. The filtration chamber 22 has a plurality of exhaust units 221 for drawing the cooled exhaust gas from the mixing compartment 120 to the filtration chamber 22 and discharging it to the outside. Specifically, the exhaust unit 221 may be located on the side wall of the filter chamber 22 or may be disposed on the upper wall. In the present embodiment, the exhaust unit 221 is located at the three side walls and the upper wall of the filter chamber 22 that are not facing the cooling space 1. In addition, in order to prevent rainwater, dust or other substances from falling into the filtering chamber 22 by the exhaust unit 221 located on the upper wall, a mask 222 is further disposed above the filtering chamber 22. The mask 222 has a plurality of gaps or holes to allow the exhaust unit 221 located on the upper wall to be smoothly vented.

The filtration chamber 22 also has a first screen 223 and a plurality of second screens 224. The first screen 223 is located at the entrance of the filtration chamber 22. In other words, the neutralization chamber 21 and the filtration chamber 22 are separated by the first screen 223, so that the first filtration is performed when the exhaust gas is sucked from the neutralization chamber 21 to the filtration chamber 22.

The second screen 224 is parallel to the side wall surface of the filter chamber 22 and is spaced apart from the wall surface of the filter chamber 22, respectively. Specifically, the second filter screen 224 is disposed on the three side walls of the filter chamber 22 that are not facing the cooling space 1, and the second filter screens 224 are spliced to each other. The second filter 224 is located at least 1 meter in front of the exhaust unit 221, respectively. Therefore, before the exhaust gas is discharged from the filter chamber 22 by the exhaust unit 221, the second filter 224 is used for the second filtering. Wherein at least one of the first screen 223 or the second screen 224 is a micro-filter which can filter fine suspended particles (ie PM 2.5).

The supporting structure 3 of the smoke cleaning device of the chimney further has a plurality of ground beams 31 disposed under the cooling space 1 and the normal temperature space 2, and extending outwards respectively to serve as a foundation for the cooling space 1 and the normal temperature space 2. In order to prevent the existing foundation of the chimney A from being excavated and deep, the ground beam 31 of the present invention is a disk extending ground beam 31, which can be buried on the ground or can be placed on the surface and covered with concrete.

When the creation is in operation, first, the exhaust gas of the factory is discharged from the chimney A to the cooling chamber 11 for cooling. In the present embodiment, the pump pumps water to the first water storage tank 41, and the water in the first water storage tank 41 can be controlled to flow into the cooling pipe 111 to cool the exhaust gas discharged from the chimney A. Through the above arrangement, the exhaust gas can be lowered from 1000 degrees Celsius immediately after exiting the chimney to 50 degrees and 60 degrees when leaving the cooling chamber 11.

Subsequently, the pumping is continued by the mixing and exhausting unit 121, and the exhaust gas is moved to the first mixing compartment 120, and sequentially descends into the rear mixing compartment 120. The ambient air is continuously driven into the mixing compartments 120 through the mixing air inlet 122, and the exhaust gas is mixed with the air to be diluted and cooled. When the exhaust gas moves vertically downward to the lowermost mixing compartment 120, the temperature of the diluted exhaust gas may be below 50 degrees Celsius, for example 45 degrees.

Then, the exhaust gas is horizontally sucked to the neutralization chamber 21 by the communication suction unit 14, and is neutralized with the neutralized gas that is neutralized by the intake port 211. Finally, the exhaust unit 221 of the filtering chamber 22 located above the neutralization chamber 21 continues to pump air, so that the exhaust gas is completely filtered through the first screen 223 and the second screen 224 to complete the purification of the exhaust gas. Exhausted in all directions.

When the exhaust gas enters the neutralization chamber 21 from the lowermost mixing compartment 120, the moving direction of the exhaust gas changes from vertically downward to horizontal, and when the neutralization chamber 21 enters the filtration chamber 22, the moving direction of the exhaust gas is more From horizontal movement to vertical upward movement. In other words, when the exhaust gas enters the inner filter chamber 22 from the lowermost mixing compartment 120 through the neutralization chamber 21, the moving direction of the exhaust gas is changed 90 degrees by 90 degrees. At the same time as the moving direction changes, the fine dust particles in the exhaust gas will fall.

Next, please refer to FIG. 3 and FIG. 4 to illustrate a second embodiment of the present creation. The second embodiment is similar to the first embodiment except that the water supply system 4 of the smoke cleaning device of the second embodiment further has a second water storage tank 42A, a third water storage tank 43A, a first tube 44A, A second tube 45A and a pressure pump 46A.

The second water storage tank 42A is located below the cooling pipe 111 and communicates with the lower end of the cooling pipe 111, so that the hot water converted into water after the water passes through the cooling pipe 111 and is cooled can be stored in the second water storage tank 42A. The second water storage tank 42A is further connected downwardly to a water tap 421A, so that the hot water can be directly used.

The third water storage tank 43A communicates with the second water storage tank 42A through the first pipe 44A. Specifically, the lower end of the first pipe 44A communicates with the third water storage tank 43A, and the upper end communicates with the second water storage tank 42A at an eight-part full position, so that when the second water storage tank 42A is full, the water can be drained. To the third water storage tank 43A.

The first tube 44A covers the outside of the filtering chamber 22, specifically, a "Z"-shaped path covering the three sides of the filtering chamber 22 that are not facing the cooling space 1. Therefore, when the filtration chamber 22 is exhausted, the discharged normal temperature exhaust gas cools the hot water flowing in the first tube 44A.

One end of the second tube 45A communicates with the third water storage tank 43A, the other end communicates with the first water storage tank 41A, and the pressure pump 46A is disposed at the second tube 45A. Therefore, the pressurizing pump 46A can transport the still-cooled water in the third water storage tank 43A to the first water storage tank 41A, and can be recycled again. In addition, the water supply system 4 can also have a sensor 47A disposed in the first water storage tank 41A for detecting the water level in the first water storage tank 41A. When the water level in the first water storage tank 41A is too low, the sensor 47A automatically activates the pressurizing pump 46A to transfer water from the third water storage tank 43A to the first water storage tank 41A.

Next, please refer to FIG. 5 and FIG. 6 to explain a third embodiment of the present creation. The third embodiment is similar to the first embodiment except that the support structure 3 of the smoke cleaning device of the third embodiment can further have a plurality of piles 32B which are respectively disposed at the end of the ground beam 31B and are vertically nailed into the ground. Deep, and the upper end of the ground beam 31B can be exposed to the surface and extend upward. The position where the ground beam 31B is driven can be any position on the circumference B of the circle made by the cooling space 1 or the normal temperature space 2 as the center of the circle. In addition, another difference is that the support structure 3 can also have a cable 33B, one end of which is fixed to the cooling space 1 or the normal temperature space 2, and the other end can be fixed to the pile 32B.

In other embodiments, the neutralization chamber 21 can also be driven with normal air so that the neutralization chamber 21 acts like other mixing compartments 120 and is diluted to reduce harmful substances in the exhaust gas.

In summary, the present invention causes the industrial exhaust gas to lower the temperature through the cooling chamber 11 and the mixing compartment 120, neutralize the neutralization gas through the neutralization chamber 21, and pass through the filtration chamber 22 by the first filter 223 and the first The second filter 224 filters the harmful substances in the exhaust gas to a large extent, so that after being discharged to the atmosphere, it does not burden the environment and can conform to international regulations. In addition, the water used for cooling the exhaust gas can be directly used after being converted into hot water, and the converted hot water can be recycled to the cooling exhaust gas after being cooled down, so that the water can be used more effectively.
