Description

Technical Field

[0001] The present invention relates to the technical field of waste gas filtration, and particularly to a high-pressure waste gas filtration device for chemical equipment. Background Art

[0002] During the production of chemical industry equipment, a large amount of smoke waste gas is generally discharged. In order to prevent environmental pollution caused by the smoke waste gas, corresponding filtration equipment is generally required to treat the dust particles in the waste gas, and the waste gas can only be discharged after being treated to meet the emission standards; after retrieval, the Chinese invention patent with the publication number of CN111643987A discloses a waste gas filtration device for chemical equipment. Through the change of the filter plate structure and the rotatable design of the filter cylinder, on the one hand, the filter cylinder can perform purification operations evenly and wear evenly, and on the other hand, through circular motion, the impurities intercepted on the surface of the filter cylinder can be automatically discharged under the action of gravity, which is beneficial to ensuring the cleanliness of the surface of the filter cylinder.

[0003] When the above waste gas filtration device conducts high-pressure filtration treatment on waste gas, the built-in filter cylinder can be used to filter the high-pressure waste gas. Through the rotation of the filter cylinder and the spiral cleaning brush, the cleaning work of the filter residue on the outer surface of the filter cylinder can be formed; however, when the filtration device is working, it lacks the functions of pressure detection and self-cleaning. As a result, during high-pressure filtration work, due to the high internal pressure intensity, the staff cannot timely understand its internal pressure intensity, which may lead to equipment failures. Moreover, the operation of this waste gas filtration device requires an additional electric drive component for driving, and it cannot process high pressure in real time, reducing the energy conservation and environmental protection performance of the waste gas high-pressure filtration device.

Through the setting of the automatic trigger control component, it is used to detect the pressure inside the high-pressure filtration component. When the pressure is too high, it means that the filter cylinder is seriously polluted, and the filter cylinder can be synchronously vibrated to remove slag, having good pressure detection function and vibration slag removal function, and solving the problem that when the high-pressure filtration device in the prior art conducts high-pressure filtration, when the filter element is seriously blocked and high-pressure filtration cannot be carried out, continuous injection of gas is likely to cause damage or explosion inside the high-pressure filtration device.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides an exhaust gas high-pressure filtration device for chemical equipment, which has the following beneficial effects:

[0020] 1. Through the setting of the filter cylinder, the present invention is used for high-pressure filtration treatment of exhaust gas in the chemical industry. By installing the filter cylinder with a plurality of connecting springs, it is convenient for the filter cylinder to vibrate and shake while ensuring that the filter cylinder can perform high-pressure filtration on the exhaust gas. Through the setting of the automatic trigger control part, it is used to detect the pressure inside the high-pressure filtration part. When the pressure is too high, it means that the filter cylinder is seriously polluted, and the filter cylinder can be synchronously vibrated to remove slag.

[0021] 2. Through the setting of the three-way valve, the present invention is used to control the air inlet port of the housing. It is not only convenient for the exhaust gas inside the air inlet main pipe to enter the inside of the housing through the air inlet port to form high-pressure filtration work, but also convenient for the pure gas injected into the air inlet main pipe to enter the output pipe through the anti-scouring pipe, enter the inside of the filter cylinder through the output pipe, and form high-pressure anti-scouring work on the filter residue on the outer surface of the filter cylinder.

At this time, the liquid medicine and the waste gas pressure inside the treatment tank are in a balanced state. As the extracted gas inside the circulation cylinder is discharged back into the treatment tank again, the waste gas inside the treatment tank can be pressurized, enabling the waste gas inside the treatment tank to form a high-pressure filtration operation, thereby improving its waste gas filtration performance and further enhancing the functionality and practicality of the water circulation component.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1:

[0039] Referring to the attached Figures 1 to 8 , the waste gas high-pressure filtration device for chemical equipment includes a treatment tank 1 and a high-pressure filtration mechanism 2 connected to the treatment tank 1. The high-pressure filtration mechanism 2 includes an intake main pipe 21 and an exhaust main pipe 22. The output end of the exhaust main pipe 22 is connected inside the treatment tank 1. A number of high-pressure filtration elements 24 arranged in parallel or in series are provided between the intake main pipe 21 and the exhaust main pipe 22;

[0040] Through the setting of the high-pressure filtration mechanism 2, it is used for high-pressure filtration treatment of waste gas in the chemical industry. Through the setting of the treatment tank 1, it is used for secondary high-pressure filtration and purification treatment of the waste gas after high-pressure filtration, thereby improving its waste gas treatment performance. By providing a number of high-pressure filtration elements 24 arranged in parallel or in series between the intake main pipe 21 and the exhaust main pipe 22, not only can multi-level high-pressure filtration of the waste gas be improved, but also high-pressure filtration work can be carried out on a large amount of waste gas;

[0041] Referring to the attached Figure 1 、 Figure 2 and Figure 5 , it can be understood that the high-pressure filtration elements 24 in the high-pressure filtration mechanism 2 are installed in parallel, or several high-pressure filtration elements 24 can be installed in series in sequence to meet the waste gas treatment work under different actual conditions.

[0042] The high-pressure filter element 24 includes a cylindrical housing 241 and a cap 242 detachably mounted on the top of the housing 241 by a plurality of fastening bolts. A filter cartridge 244 is fixedly installed at the bottom of the cap 242 by a plurality of connecting springs 243. An output pipe 245 is fixedly connected to the top of the cap 242. An automatic trigger control member 249 for vibrating the filter cartridge 244 is provided inside the housing 241;

[0043] By detachably installing the cap 242 and the housing 241 with a plurality of fastening bolts, it is convenient for later staff to replace or disassemble and clean according to the condition of the filter cartridge 244 inside each high-pressure filter element 24. Through the setting of the filter cartridge 244, it is used for high-pressure filtration treatment of waste gas in the chemical industry. By installing the filter cartridge 244 with a plurality of connecting springs 243, it is convenient for the filter cartridge 244 to vibrate and shake while ensuring that the filter cartridge 244 can perform high-pressure filtration on the waste gas. Through the setting of the automatic trigger control member 249, it is used to detect the pressure inside the high-pressure filter element 24. When the pressure is too high, it means that the filter cartridge 244 is seriously polluted, and the filter cartridge 244 can be synchronously vibrated to remove slag, having good pressure detection function and vibration slag removal function.

[0044] Refer to the appendix Figure 6 and Figure 7 One end of the output pipe 245 extends into the interior of the filter cartridge 244 through a sealing sleeve. The other end of the output pipe 245 is connected to the interior of the exhaust main pipe 22 through a connecting pipe 23. An air inlet port is provided on the outer surface of the housing 241, and the air inlet port is connected to the interior of the air inlet main pipe 21. A drain pipe 246 is installed on one side of the bottom of the housing 241.

[0045] Through the setting of the sealing sleeve, not only is the connection between the output pipe 245 and the interior of the filter cartridge 244 ensured, but also the swinging movement of the filter cartridge 244 is not affected. The specific setting of the bottom end of the output pipe 245 may include a soft pipe and a hard pipe, and the hard pipe is fixedly connected to the interior of the filter cartridge 244. Through the setting of the soft pipe, it is convenient for the swinging of the filter cartridge 244;

[0046] By fixedly connecting the output pipe 245 to the exhaust main pipe 22 through the connecting pipe 23, it is convenient for the gas after high-pressure filtration by the high-pressure filter element 24 to enter the exhaust main pipe 22 to form a unified export operation. Through the setting of the drain pipe 246, it is used to export the filter residue on the filter cartridge 244.

[0047] Refer to the appendix Figure 7 and Figure 8, the automatic trigger control member 249 includes a piston cylinder 2491 fixed to the bottom of the housing 241. A piston block 2492 is slidably connected inside the piston cylinder 2491. A toggle block 2493 is fixedly connected to the top of the piston block 2492. A plurality of isosceles trapezoid-shaped protrusions are fixedly connected to one side of the toggle block 2493. A U-shaped rod 2494 is fixedly connected to the bottom of the filter cartridge 244, and the U-shaped rod 2494 contacts one side of the toggle block 2493. An extrusion spring 2495 for upwardly extruding the piston block 2492 is fixedly connected inside the piston cylinder 2491;

[0048] Through the elastic force of the extrusion spring 2495 itself, the piston block 2492 can be extruded upward, so that the piston block 2492 is in a reset state. The elastic value of the extrusion spring 2495 is greater than or equal to the pressure during high-pressure filtration inside the high-pressure filter member 24. So that when the high-pressure filter member 24 is normally performing high-pressure filtration, its piston block 2492 is always in the initial reset state;

[0049] When the outer surface of the filter cartridge 244 is covered with filter residues and the filter residues seriously block the filter holes on the outer surface of the filter cartridge 244, the pressure inside the housing 241 will gradually increase. When the pressure inside the housing 241 is greater than the extrusion spring 2495, the pressure inside the housing 241 can extrude the piston block 2492, causing the piston block 2492 to move downward. The downward movement of the piston block 2492 can drive the toggle block 2493 to move downward. The downward movement of the toggle block 2493 can cause a plurality of isosceles trapezoid-shaped protrusions to shake the U-shaped rod 2494, thereby driving the filter cartridge 244 to vibrate. Through the vibration of the filter cartridge 244, the filter residues on the outer surface of the filter cartridge 244 can be removed. When it is cleared to the point where high-pressure filtration can be performed, through the elastic extrusion of the extrusion spring 2495 on the piston block 2492, the piston block 2492 can be reset, solving the problem in the prior art that when a high-pressure filtration device is performing high-pressure filtration and the filter element is severely blocked and high-pressure filtration cannot be performed, continuous gas injection is likely to cause damage or explosion inside the high-pressure filtration device.

[0050] Refer to the appendix Figure 8 , the bottom of the piston cylinder 2491 is fixedly connected with a touch counter 2496 through a connecting frame, and a touch block 2497 for triggering the touch counter 2496 is fixedly connected to the bottom of the piston block 2492;

[0051] Through the downward movement of the piston block 2492, the touch block 2497 can be driven to move downward synchronously. When the touch block 2497 moves to the touch end of the touch counter 2496, the touch counter 2496 can be touched, and the touch counter 2496 can be used for counting. By knowing the value counted by the touch counter 2496, the serious situation of the filter residue pollution inside the high-pressure filter element 24 can be understood, and the work of timely cleaning and treatment can be formed.

[0052] Refer to the appendix Figure 2 , a discharge pipe is fixedly connected to the top of the treatment tank 1, a filter tank 3 is fixedly connected to the inner surface of the treatment tank 1, and an adsorption material is contained inside the filter tank 3. An ultrasonic generator 5 is installed at the bottom of the inner wall of the treatment tank 1 through a protective cover 4;

[0053] Through the setting of the filter tank 3, it is used for filtering and treating the waste gas rising inside the treatment tank 1. By containing an adsorption material, such as activated carbon, inside the filter tank 3, the fine particles and irritating odors in the waste gas can be adsorbed and treated, thereby improving the diversity of waste gas treatment.

[0054] Refer to the appendix Figures 1 to 4 , a liquid medicine for treating waste gas is contained inside the treatment tank 1, and a water circulation component 6 for discharging the liquid medicine inside the treatment tank 1 into the filter tank 3 is arranged on the treatment tank 1;

[0055] By containing a liquid medicine for acutely treating waste gas inside the treatment tank 1 and directly discharging it into the liquid medicine inside the treatment tank 1 through the exhaust main pipe 22, the liquid medicine can be fully contacted with the waste gas. Cooperating with the work of the ultrasonic generator 5, the waste gas bubbles in the liquid medicine can be broken, converting large bubbles into tiny bubbles, further improving the contact strength between the liquid medicine and the gas and enhancing the waste gas treatment effect;

[0056] Through the setting of the water circulation component 6, it is used for circulating and treating the liquid medicine inside the treatment tank 1, not only increasing the contact strength between the liquid medicine and the waste gas, but also spraying the waste gas during its upward movement, thereby enhancing the performance of waste gas filtration and purification treatment.

[0057] Refer to the appendix Figure 3 and Figure 4 , the water circulation component 6 includes a circulation cylinder 61 and an annular pipe plate 62 installed inside the filter tank 3. A number of liquid permeable holes are provided on the annular pipe plate 62, and the annular pipe plate 62 is located in the middle of the filter tank 3. A piston plate 63 is slidably connected inside the circulation cylinder 61. A suction pipe 64 and a drain pipe 65 are fixedly connected to the bottom of the circulation cylinder 61. Check valves are installed on both the suction pipe 64 and the drain pipe 65. One ends of the suction pipe 64 and the drain pipe 65 are respectively connected to the bottom of the treatment tank 1 and the inside of the annular pipe plate 62;

[0058] Through the upward movement of the piston plate 63, a negative pressure state can be formed at the bottom of the circulation cylinder 61. At this time, with the arrangement of the suction pipe 64, the liquid medicine inside the treatment tank 1 can be extracted. With the downward movement of the piston plate 63, the extracted liquid medicine can be squeezed, so that the liquid medicine is discharged into the inside of the annular pipe tray 62 through the drain pipe 65. Since the annular pipe tray 62 is located in the middle of the filter tank 3, it is convenient for the liquid medicine discharged through the annular pipe tray 62 to fully contact the gas filtered through the filter tank 3, forming full contact between the chemical medicine and the waste gas. The filter holes at the bottom of the filter tank 3 can spray and treat the waste gas during the upward movement, having multi-layer waste gas treatment performance;

[0059] An electric telescopic rod 66 for driving the piston plate 63 up and down is installed on the outer surface of the circulation cylinder 61, and the telescopic end of the electric telescopic rod 66 is fixedly connected to the piston plate 63 through an L-shaped reciprocating rod 67;

[0060] The electric telescopic rod 66 is connected to an external power supply and a control switch, and is used to drive the L-shaped reciprocating rod 67 up and down. The up and down movement of the L-shaped reciprocating rod 67 can drive the piston plate 63 up and down, forming the water circulation work of the water circulation assembly 6.

[0061] Embodiment 2: Different from Embodiment 1;

[0062] Refer to the appendix Figure 6 and Figure 7 , an air inlet port is arranged on the outer surface of the housing 241, and an anti-scouring pipe 248 is installed through a three-way valve 247, and one end of the anti-scouring pipe 248 is connected to the inside of the output pipe 245;

[0063] Through the setting of the three-way valve 247, it is used to control the air inlet port of the housing 241. It is not only convenient for the waste gas in the intake main pipe 21 to enter the inside of the housing 241 through the air inlet port to form a high-pressure filtration work, but also when injecting pure gas into the intake main pipe 21, the gas can enter the output pipe 245 through the anti-scouring pipe 248, and enter the inside of the filter cylinder 244 through the output pipe 245 to form a high-pressure anti-scouring work on the filter residue on the outer surface of the filter cylinder 244. With the opening of the drain pipe 246, the export work of the filter residue can be formed, having good anti-scouring cleaning work, and further improving the service life and convenience of the high-pressure filter element 24.

[0064] Embodiment 3: Different from Embodiment 1;

[0065] Refer to the appendix Figure 3 and Figure 4, a filter 68 is detachably installed on the suction pipe 64. The one-way valve on the suction pipe 64 is located at the water inlet end of the filter 68. The top of the circulation cylinder 61 is fixedly communicated with a pressure pipe 69. One end of the pressure pipe 69 extends into the interior of the treatment tank 1, and one end of the pressure pipe 69 is located in the gas layer between the filter tank 3 and the liquid medicine. One end of the pressure pipe 69 is fixedly communicated with an auxiliary pipe 610, and the bottom end of the auxiliary pipe 610 is located in the middle layer of the liquid medicine;

[0066] Through the setting of the filter 68, sundries in the liquid circulated and sucked through the suction pipe 64 can be filtered, so as to ensure that each time the water circulation assembly 6 circulates the liquid medicine, multiple filtering operations can be carried out synchronously, thereby ensuring the purity of the liquid medicine, improving its waste gas treatment performance. Since the one-way valve on the suction pipe 64 is located at the water inlet end of the filter 68, it is avoided that the sundries filtered by the filter 68 re-enter the treatment tank 1, thus ensuring the stability during the collection of sundries;

[0067] Since the top of the circulation cylinder 61 is fixedly communicated with the pressure pipe 69, when the piston plate 63 moves downward, a negative pressure state will be formed above the piston plate 63. Thus, a part of the waste gas inside the treatment tank 1 can be extracted through the pressure pipe 69. When the piston plate 63 moves upward and resets, the piston plate 63 can squeeze the extracted gas. At this time, the pressure of the liquid medicine and the waste gas inside the treatment tank 1 is in a balanced state. As the extracted gas inside the circulation cylinder 61 is discharged back into the interior of the treatment tank 1 again, the waste gas inside the treatment tank 1 can be pressurized, so that the waste gas inside the treatment tank 1 forms a high-pressure filtration operation, thereby improving its waste gas filtration treatment performance and further enhancing the functionality and practicality of the water circulation assembly 6;

[0068] By installing the auxiliary pipe 610 on the pressure pipe 69, when the waste gas is sucked through the pressure pipe 69, it is convenient to absorb a part of the liquid medicine. With the reverse export of the pressure pipe 69, the liquid medicine and the waste gas can be sprayed out synchronously, further improving the contact effect between the waste gas and the liquid medicine and enhancing its waste gas treatment performance.

[0069] It should be noted that the term "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0070] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
