Description

Technical Field

[0001] This application relates to the technical field of waste gas treatment, and more particularly to a waste gas purification device. Background Technology

[0002] The first treatment stage in waste gas purification primarily treats flue gas. The waste gas entering the flue gas treatment system often contains complex components, including but not limited to dust, sticky impurities, and organic waste gases. These components adhere to the surface of the packing layer as they pass through it. Especially when the waste gas treatment system cannot completely remove these impurities, they gradually accumulate and reduce the passage gaps for the waste gas, potentially causing blockages.

[0003] In the original waste gas purification process, the relevant operators usually adopted the method of regular inspection and maintenance to deal with the problem of impurities accumulating over a long period of time and gradually reducing the gaps in the passage of waste gas. However, this method requires shutdown for inspection and maintenance, and cleaning is time-consuming and labor-intensive, which affects the purification efficiency of waste gas.

Detailed Implementation

[0024] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0025] The exhaust gas purification device of this application embodiment will now be described with reference to the accompanying drawings.

[0026] like Figures 1-5 As shown, the exhaust gas purification device of this application embodiment may include a housing 1, multiple spray components 2, a first packing 3, a second packing 4, a third packing 5, a drive component 6, and an air jet component 7.

[0027] The housing 1 is provided with a first partition 10, a second partition 11, a third partition 12 and a fourth partition 13 in sequence, which divide the housing 1 into a first processing section 14, an air passage 15, a second processing section 16, a third processing section 17 and an exhaust passage 18.

[0028] It is understandable that the second partition 11, the third partition 12 and the fourth partition 13 can be arranged in an alternating manner, that is, the second partition 11 is set at the inner top of the box 1, the third partition 12 is set at the inner bottom of the box 1 and the fourth partition 13 is set at the inner top of the box 1, so that the exhaust gas can fully contact the first packing 3, the second packing 4 and the third packing 5, thereby ensuring the purification effect of the exhaust gas.

[0029] The housing 1 has an air inlet 19 and an exhaust outlet 190. The exhaust outlet 190 is equipped with a fan 191 and an air flow meter 192.

[0030] It should be noted that the suction device 191 described in this embodiment is a common suction device on the market, and will not be described in detail here. The suction device 191 can drive the exhaust gas to flow in the box 1, thereby ensuring the purification effect of the exhaust gas.

[0031] Understandably, by setting the air flow meter 192, when the air flow meter 192 detects that the gas flow through the exhaust port 190 has decreased to a certain value range, it transmits a signal to the controller (not shown in the figure). The controller controls the spray assembly 2 and the jet assembly 7 to perform work, thereby cleaning the impurities at the first filler 3.

[0032] Multiple spraying components 2 are respectively installed on the housing 1, and the multiple spraying components 2 are sequentially installed above the first treatment section 14, the second treatment section 16 and the third treatment section 17.

[0033] It should be noted that the spray assembly 2 described in this embodiment is a commercially available spray component, capable of spraying chemical solvents onto the filler. Each spray device includes a water tank (not shown in the figure), a water pump (not shown in the figure), and a spray pipe (not shown in the figure). One end of the water pump is connected to the water tank, and the other end of the water pump is connected to the spray pipe. In addition, a spray pipe is provided on the first filler 3, the second filler 4, and the third filler 5, that is, a spray assembly 2 is provided on the first treatment section 14, the second treatment section 16, and the third treatment section 17, thereby conveniently meeting different spraying needs.

[0034] The first packing 3 is disposed in the first processing section 14, the second packing 4 is disposed in the second processing section 16, and the third packing 5 is disposed in the third processing section 17.

[0035] It is understandable that the first packing 3 can be used to treat flue gas, the second packing 4 can be used for desulfurization or denitrification, and the third packing 5 can be used to treat volatile gases. The specific settings can be adjusted according to the actual working conditions.

[0036] It should be noted that, in this embodiment, the bottom of the first packing 3 is provided with a supporting mesh plate (not shown in the figure), one end of which is connected to the housing 1, and the other end of which is connected to the first partition 10. Additionally, the bottoms of the second packing 4 and the third packing 5 are respectively provided with supporting mesh plates, with one end of the supporting mesh plate of the second packing 4 connected to the second partition 11, and the other end of the supporting mesh plate of the second packing 4 connected to the third partition 12. Similarly, one end of the supporting mesh plate of the third packing 5 is connected to the third partition 12, and the other end of the supporting mesh plate of the second packing 4 is connected to the fourth partition 13.

[0037] The drive assembly 6 and the jet assembly 7 are respectively mounted on the housing 1; the jet assembly 7 may include a jet box 70, a piston 71 and a one-way air inlet 72.

[0038] The jet box 70 is mounted on the housing 1. A first one-way valve 700 is mounted on the jet box 70. A piston 71 is slidably sealed to the inner wall of the jet box 70. One end of the piston 71 is connected to the drive assembly 6. One end of the one-way air inlet 72 is connected to one side of the jet box 70. The other end of the one-way air inlet 72 is located in the first processing section 14 and below the first packing 3.

[0039] Understandably, the drive assembly 6 is used to control the reciprocating extension and retraction of the piston 71 within the jet box 70, thereby ensuring that the jet box 70 delivers air to the one-way air intake 72.

[0040] It should be noted that the piston 71 described in this embodiment slides to separate the jet box 70 into an exhaust section and an intake section. The intake section is used to draw exhaust gas into the first processing section 14, and the exhaust section is used to exhaust gas into the one-way air purging member 72. In addition, the first one-way valve 700 is connected to the exhaust section, and the first one-way valve 700 is used to unilaterally absorb external air into the exhaust section inside the jet box 70, thereby facilitating the jet box 70 to deliver uncontaminated air to the one-way air purging member 72. When the piston 71 pushes the air in the exhaust section, the air will not leak out from the first one-way valve 700, thereby ensuring the air purging effect of the one-way air purging member 72.

[0041] It is understandable that by setting up the one-way air flushing component 72, the gel-like impurities adsorbed at the first filler 3 can be flushed away, causing the impurities to detach from the first filler 3 and fall out of the first filler 3, or they can be flushed down by the spraying component 2, thereby achieving the cleaning of impurities at the first filler 3.

[0042] Specifically, in actual operation, relevant personnel start the device, the suction fan works, and the exhaust gas is drawn from the air inlet 19 into the first packing 3 in the first treatment section 14, where the flue gas and other impurities in the exhaust gas are purified. The exhaust gas then flows through the first partition 10 and the air passage 15 to the bottom of the second packing 4 in the second treatment section 16. The second packing 4 purifies the sulfur, pyroxene, or nitrogen oxides in the exhaust gas. The exhaust gas continues to flow to the third packing 5 in the third treatment section 17 for the purification of volatile gases, and is discharged from the exhaust passage 18 and the exhaust port 190. The air flow meter 192 detects the gas flow at the exhaust port 190, and the spray assembly 2 sprays chemical solvents onto the corresponding packing during the exhaust gas purification process, thereby ensuring the purification quality of the exhaust gas.

[0043] After a period of use, the first packing 3 reacts with the exhaust gas, forming adhering impurities that gradually block the pores on the first packing 3. At this time, the air flow meter 192 at the exhaust port detects that the air flow rate has reached a certain range. The controller controls the drive component 6 to do work, and the drive component 6 drives the piston 71 to move on one side inside the jet box 70, thereby pushing the gas at one end of the jet pipe to the one-way air jet component 72. The one-way air jet component 72 blows the ejected gas toward the bottom of the first packing 3, thereby flushing away the impurities adhering to the first packing 3, causing them to detach from the first packing 3 and fall out. In addition, the controller controls the spray component 2 on the first packing 3 to spray the first packing 3, thereby flushing the impurities out of the first packing 3, thus completing the cleaning of impurities without the need for inspection and maintenance, thereby improving the purification efficiency of the exhaust gas.

[0044] In one embodiment of this application, such as Figure 2 and Figure 5As shown, the jet assembly 7 may also include a one-way intake pipe 73 and a one-way exhaust pipe 74.

[0045] One end of the one-way intake pipe 73 is connected to one side of the jet box 70, and the other end of the one-way intake pipe 73 is connected to the first processing section 14 and located above the first packing 3. One end of the one-way exhaust pipe 74 is connected to one side of the jet box 70, and the other end of the one-way exhaust pipe 74 is connected to the air passage 15. A valve 100 is provided on the first partition 10.

[0046] Understandably, by setting up the one-way suction pipe 73, the exhaust gas above the first packing 3 can be sucked up. During the suction process, the adsorbed impurities can be flushed with gas to a certain extent, thereby improving the removal effect of impurities on the first packing 3. In addition, by setting up the one-way suction pipe 73, the exhaust gas flow rate can be increased when the first packing 3 is blocked to a certain extent, thereby ensuring the purification efficiency of the exhaust gas.

[0047] Understandably, by setting up the one-way exhaust pipe 74, when the piston 71 completes a single push and returns to the initial position, the exhaust gas drawn from the one-way intake pipe 73 on one side of the piston 71 can be discharged from the one-way exhaust pipe 74 to the gas passage 15, so that this part of the exhaust gas continues to flow and be purified in the second treatment section 16 and the third treatment section 17, thereby ensuring the purification quality of the exhaust gas by this device.

[0048] Understandably, by setting the valve 100, when the piston 71 moves toward the jet box 70 and draws in the exhaust gas from the first packing 3, the controller controls the valve 100 to close, thereby preventing the one-way suction pipe 73 from drawing in the already purified exhaust gas to the second processing section 16 or the third processing section 17, thus ensuring the purification efficiency of the exhaust gas.

[0049] It should be noted that the valve 100 described in this embodiment includes an electric telescopic rod 1000 and a plug valve 1001. The electric telescopic rod 1000 is disposed in a sealing groove opened in the first partition 10. The plug valve 1001 is slidably connected to the first partition 10 and connected to the extension shaft of the electric telescopic rod. The plug valve 1001 slidably seals the vent hole opened on the first partition 10, thereby ensuring the absorption effect of the one-way suction pipe 73 on the exhaust gas on the first packing 3. In addition, the valve 100 on the first partition 10 can also be other valves 100 commonly found on the market, which will not be described in detail here.

[0050] In one embodiment of this application, such as Figure 2 and Figure 5 As shown, the one-way air-inflating component 72 may include a second one-way valve 720, a pressurization pipe 721, an air-inflating pipe 722, and a plurality of air-inflating heads 723.

[0051] The second check valve 720 is located on one side of the jet box 70. One end of the booster pipe 721 is connected to the second check valve 720, and the other end of the booster pipe 721 is connected to the air inlet pipe 722. The air inlet pipe 722 is located on the first processing section 14 and below the first packing 3. Multiple air inlet heads 723 are respectively located on the air inlet pipe 722, and the air inlet pipe 722 is located below the first packing 3.

[0052] In this embodiment, the second one-way valve 720 is used to discharge gas in the jet box 70 to the booster pipe 721 in one direction.

[0053] It should be noted that, in this embodiment, the diameter of the end of the booster pipe 721 connected to the second one-way valve 720 is larger than the diameter of the end of the booster pipe 721 connected to the air-filling pipe 722, thereby achieving the effect of increasing air volume and ensuring that the air ejected from the air-filling head 723 can effectively remove adhering impurities.

[0054] In one embodiment of this application, such as Figure 2 and Figure 5 As shown, the one-way intake fitting 73 may include a third one-way valve 730 and an intake pipe 731.

[0055] The third one-way valve 730 is located inside the housing 1 and within the first processing section 14, and is positioned above the first packing 3. One end of the air inlet pipe 731 is connected to the third one-way valve 730, and the other end of the air inlet pipe 731 is connected to one side of the jet box 70.

[0056] In this embodiment, the third check valve 730 is used to draw exhaust gas from above the first packing 3 and deliver it into the inlet pipe 731 in a one-way manner.

[0057] In one embodiment of this application, such as Figure 2 and Figure 5 As shown, the one-way exhaust pipe 74 may include a fourth one-way valve 740 and an exhaust pipe 741.

[0058] The fourth one-way valve 740 is located on one side of the jet box 70 and is connected to the jet box 70. One end of the exhaust pipe 741 is connected to the fourth one-way valve 740, and the other end of the exhaust pipe 741 is connected to the air passage 15.

[0059] In this embodiment, the fourth one-way valve 740 is used to discharge the exhaust gas drawn into the jet box 70 into the gas passage 15 in one direction.

[0060] In one embodiment of this application, such as Figure 2 and Figure 4 As shown, piston component 71 may include piston rod 710 and piston head 711.

[0061] The piston head 711 is slidably sealed inside the jet box 70, the piston rod 710 is slidably sealed to the jet box 70, one end of the piston rod 710 is connected to the piston rod 710, and the other end of the piston rod 710 is connected to the drive assembly 6.

[0062] It is understandable that the intake and exhaust of air or exhaust gas in the jet box 70 are achieved by the sliding seal of the piston head 711 within the jet box 70.

[0063] In one embodiment of this application, such as Figure 2 and Figure 4 As shown, the drive assembly 6 may include a motor 60, a reciprocating lead screw 61, a support block 62, and a drive block 63.

[0064] The motor 60 is mounted on the housing 1, the reciprocating screw 61 is mounted on the support block 62, and one end of the reciprocating screw 61 is connected to the output shaft of the motor 60. The support block 62 is mounted on the housing 1, the drive block 63 is slidably mounted on the housing 1, the drive block 63 is sleeved on the reciprocating screw 61, and one end of the piston rod 710 is connected to the drive block 63.

[0065] It is understandable that by setting the reciprocating screw 61, the drive block 63 can move back and forth on the reciprocating screw 61, and drive the piston rod 710 and piston head 711 to move back and forth in the jet box 70, thereby achieving the jet effect of the jet box 70.

[0066] Specifically, in actual operation, relevant personnel start the device, the suction fan works, and the exhaust gas is drawn from the air inlet 19 into the first packing 3 in the first treatment section 14, where the flue gas and other impurities in the exhaust gas are purified. The exhaust gas then flows through the first partition 10 and the air passage 15 to the bottom of the second packing 4 in the second treatment section 16, where the second packing 4 purifies the sulfur, pyroxene, or nitrogen oxides in the exhaust gas. The exhaust gas continues to flow to the third packing 5 in the third treatment section 17 for the purification of volatile gases, and is discharged from the exhaust passage 18 and the exhaust port 190. The air flow meter 192 detects the gas flow at the exhaust port 190, and the spray assembly 2 sprays chemical solvents onto the corresponding packing during the exhaust gas purification process, thereby ensuring the purification quality of the exhaust gas.

[0067] After a period of use, the first packing 3 reacts with the exhaust gas, forming adhering impurities that gradually block the pores on the first packing 3. At this time, the air flow meter 192 at the exhaust port detects that the air flow rate has reached a certain range. The controller controls the motor 60 to rotate, which in turn drives the reciprocating screw 61 to rotate. The reciprocating screw 61 drives the drive block 63 to move on the reciprocating screw 61, causing the drive block 63 to push the piston rod 710 and the piston head 711 towards one end of the jet box 70. During the movement of the piston head 711 (at this time, the controller controls the valve 100 to close the first partition), (Ventilation hole on 10), the air on one side of the piston head 711 is compressed and flows from the second one-way valve 720 into the booster pipe 721. The booster pipe 721 compresses the air, and the air flows from the booster pipe 721 to the air inflator pipe 722. The compressed air is sprayed out from the air inflator 723 and washes away the adhering impurities at the first packing 3, thereby removing the adhering impurities from the first packing 3. The controller then controls the spray assembly 2 above the first packing 3 to spray the solution. The solution washes the first packing 3 and further washes away the impurities, causing the impurities to fall from the first packing 3 to the bottom of the box 1.

[0068] Simultaneously, when the piston head 711 moves towards one end of the jet box 70, a negative pressure space is formed in the jet box 70 on the other side of the piston head 711. This allows the exhaust gas on the first packing 3 to enter the negative pressure space through the third one-way valve 730 and the air inlet pipe 731. When the exhaust gas on the first packing 3 is sucked in, the flow rate of the exhaust gas from the bottom of the first packing 3 to the top of the first packing 3 is increased. This, in conjunction with the air flushing head 723, further removes the impurities adhering to the first packing 3, thereby improving the removal effect of the impurities.

[0069] In addition, during the process of the reciprocating screw 61 driving the drive block 63, piston rod 710, and piston head 711 to return to their initial positions (at which time the controller controls the valve 100 to open), a negative pressure space is formed on one side of the piston head 711, thereby drawing in external air from the first one-way valve 700 for the next use. The exhaust gas drawn from above the first packing 3 on the other side of the piston head 711 is compressed by the piston head 711 and transported through the fourth one-way valve 740 and the exhaust pipe 741 to the past channel, and continues to flow to the second processing section 16 and the third processing section 17. After each component returns to its initial position, the air flow meter 192 continues to monitor. Once the normal range is reached, the work of the jet assembly 7 stops. If the normal range is not reached, the jet assembly 7 continues to perform the above work, thereby completing the cleaning of impurities at the first packing 3 without the need for inspection and maintenance, thus improving the purification efficiency of the exhaust gas.

[0070] In summary, the exhaust gas purification device of this application uses gas flushing to flush impurities on the packing material, and then uses solution spraying to further flush the impurities, thereby ensuring the purification effect of the exhaust gas, and eliminating the need for relevant operators to stop the machine for inspection and maintenance, thus improving the purification efficiency of the exhaust gas.
