Description

Technical Field

[0001] This utility model relates to the field of road safety protection technology, and more specifically, to a waste gas treatment device for environmental engineering. Background Technology

[0002] Environmental engineering primarily studies how to protect and rationally utilize natural resources, and how to solve increasingly serious environmental problems using scientific methods. Its core focuses on the control of environmental pollution sources and the treatment of environmental waste gas. Waste gas treatment mainly refers to the process of achieving national standards for gas emissions through a series of reactions or devices. Environmental waste gas also requires treatment to remove dust and other harmful substances, thus necessitating the use of waste gas treatment devices.

[0003] However, after prolonged use, small fine particles can clog the filter screen of the exhaust gas treatment device. If the filter screen is clogged and cannot be treated, it will affect the subsequent filtration effect. Since the filter plate is located inside the filtration device, it needs to be disassembled for manual cleaning or replacement, which increases the labor intensity and also affects the continuity and efficiency of exhaust gas treatment when the equipment is shut down.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0036] like Figure 1-6 As shown, an environmental engineering waste gas treatment device includes:

[0037] The outer processing box 1 is used, and the inner processing box 3 is fixedly installed inside the outer processing box 1.

[0038] The two primary filter sections 2 are symmetrically arranged on the outer processing box 1, and the upper ends of the two primary filter sections 2 are connected to the inner processing box 3, for performing preliminary filtration treatment on the exhaust gas.

[0039] Secondary filtration section 4 is disposed inside the processing inner box 3 and is used for secondary filtration of exhaust gas;

[0040] Gas delivery unit 5 is installed on the outer casing 1 of the processing unit and is connected to the two primary filter units 2;

[0041] Cleaning unit 6 is installed inside the processing inner box 3 and the two primary filter units 2;

[0042] Opening and closing parts 7, the two opening and closing parts 7 are respectively assembled on the two primary filter parts 2, wherein

[0043] The gas conveying unit 5 alternately conveys the exhaust gas to the two secondary filter units 4, and then conveys it into the secondary filter unit 4;

[0044] The cleaning section 6 is used to clean the two primary filters 2 alternately during the process of treating exhaust gas.

[0045] In use, the air supply unit 5 alternately delivers exhaust gas from the exhaust gas source or external exhaust gas collection system to the two primary filter units 2 for preliminary treatment. If the filter plate 9 in one primary filter unit 2 becomes clogged, the other primary filter unit 2 immediately takes over the exhaust gas treatment, while the first primary filter unit 2 is in a resting state. Simultaneously, under the control of the cleaning unit 6, the filter plate 9 in the resting primary filter unit 2 can be effectively cleaned, avoiding manual removal and cleaning of the filter plate 9, effectively reducing manual intervention, labor intensity, and maintenance costs. Furthermore, when the two primary filter units 2 are used alternately again, To ensure effective filtration of the exhaust gas by the primary filter 2, the system eliminates the need to stop the machine to clean the clogged filter plate 9 during exhaust gas treatment, thus ensuring the continuity and efficiency of exhaust gas treatment. Simultaneously, since the cleaning unit 6 cleans the primary filter 2 during the maintenance process, it effectively avoids the impact of airflow on the cleaning of the filter plate 9, ensuring the cleaning effect of the filter plate 9. After the exhaust gas undergoes preliminary treatment by the primary filter 2, it is transported to the inner treatment chamber 3 for secondary treatment. This allows harmful gases and dust in the exhaust gas to be effectively adsorbed and filtered by the aqueous solution, ensuring the treatment effect and meeting customer needs.

[0046] Optionally, the primary filtration unit 2 includes a filter chamber 8 disposed on one side of the processing outer casing 1, a filter plate 9 slidably assembled in the filter chamber 8, and a door 10 hinged to the processing outer casing 1 for closing the filter chamber 8. In use, under the control of the gas supply unit 5, the exhaust gas from the exhaust gas source or external exhaust gas collection system can be transported to the filter chamber 8. Under the filtration of the filter plate 9, some impurities and dust in the exhaust gas can be effectively blocked and intercepted, thus achieving preliminary filtration treatment of the exhaust gas. Since there are two primary filtration units 2, the preliminary filtration treatment of the exhaust gas can be completed alternately, avoiding downtime and affecting the treatment efficiency of the exhaust gas.

[0047] Optionally, the gas supply unit 5 includes an air inlet pipe 11 with one end connected to the exhaust gas source or an external exhaust gas collection system, two gas supply pipes 12 installed on the processing outer box 1 and connected to the other end of the air inlet pipe 11, two electric butterfly valves 13 respectively installed on the two gas supply pipes 12, and two pressure sensors 14 respectively installed on the two doors 10 and connected to the two filter chambers 8.

[0048] The other ends of the two gas supply pipes 12 are respectively connected to the lower ends of the two filter chambers 8;

[0049] Both pressure sensors 14 and both electric butterfly valves 13 are electrically connected to an external controller. The two pressure sensors 14 can detect the pressure in the two filter chambers 8. The two pressure sensors 14 operate alternately. When one pressure sensor 14 detects an abnormal pressure in the corresponding filter chamber 8, indicating that the filter plate 9 is blocked, it will transmit an electrical signal to the external controller. The external controller will then control the other pressure sensor 14 to operate, while the sensor that detected the abnormality will stop working. At the same time, the external controller will control the two electric butterfly valves 13 to close the air supply pipe 12 connected to the filter chamber 8 with blocked filter plate 9, while keeping the other air supply pipe 12 unobstructed. This achieves the purpose of alternating exhaust gas treatment in the two primary filtration sections 2, avoiding downtime and affecting exhaust gas treatment efficiency. Meanwhile, under the control of the cleaning section 6, the filter plate 9 in the filter chamber 8 can be cleaned during the rest period to ensure normal operation of the two primary filtration sections 2 during the next alternating exhaust gas treatment.

[0050] Optionally, the secondary filtration section 4 includes two processing pipes 15 symmetrically installed inside the processing inner box 3, each connected at one end to the upper end of one of the two filter chambers 8; two processing covers 16 connected at the other end of each of the two processing pipes 15; two porous diverter plates 17 fixed inside the two processing covers 16; two spray pipes 18 symmetrically fixed inside the processing inner box 3; a plurality of first spiral nozzles 19 installed on each of the two spray pipes 18; a water supply pipe 20 connected at one end to the middle of the two spray pipes 18 and at the other end to an external water supply system; a drain pipe 21 connected to the lower end of the processing inner box 3; and an exhaust pipe 34 connected to the top of the processing inner box 3. After the exhaust gas is transported by the gas conveying section 5 to one of the primary filtration sections 2 for initial filtration... After the initial filtration, the exhaust gas is transported to the inner treatment chamber 3 through one of the treatment pipes 15. At this time, the inner treatment chamber 3 contains an aqueous solution that overflows the bottom of the two treatment hoods 16 under the supply of aqueous solution from the water supply pipe 20 and the spraying from the two spray pipes 18 and several first spiral nozzles 19. When the exhaust gas enters the treatment hood 16 through the treatment pipe 15 and is then sprayed into the inner treatment chamber 3 under the diversion of the porous diversion plate 17, it can effectively come into contact with and mix with the aqueous solution stored in the inner treatment chamber 3. During the process of passing through the inner treatment chamber 3 and being discharged through the exhaust pipe 34, it comes into contact with and mixes again with the water mist sprayed from the several first spiral nozzles 19. This allows the harmful gases and dust in the exhaust gas to be effectively adsorbed and filtered by the aqueous solution for a second time, ensuring the treatment effect of the exhaust gas.

[0051] Optionally, the cleaning unit 6 includes two cleaning pipes 22 respectively fixed in the two filter chambers 8 and disposed above the filter plate 9, a plurality of second spiral nozzles 23 respectively installed on the two cleaning pipes 22, two water supply pipes 24 with one end connected to the two cleaning pipes 22 and the other end connected to the water supply pipe 20, guide grooves 25 respectively opened at the bottom of the two filter chambers 8, two drain pipes 26 respectively connected to the bottom of the two filter chambers 8, two first solenoid valves 27 respectively installed on one of the water supply pipes 24 and the drain pipe 26, and two second solenoid valves 28 installed on the other water supply pipe 24 and the drain pipe 26;

[0052] Both first solenoid valves 27 and both second solenoid valves 28 are electrically connected to an external controller. During the alternating use of the two filter sections, the external controller can control the two first solenoid valves 27 and the two second solenoid valves 28, allowing one water supply pipe 24 and the drain pipe 26 to flow alternately with the other water supply pipe 24 and the drain pipe 26. The aqueous solution transported by the water supply pipe 20 can then be transported through the required delivery pipe to the cleaning pipe 22 in the resting filter chamber 8, and then sprayed out through several second spiral nozzles 23 to rinse the filter plate 9 in the filter chamber 8. After rinsing, the wastewater carrying dust can be discharged through the corresponding drain pipe 26, thus effectively cleaning the filter plate 9 in the resting filter chamber 8. This facilitates the subsequent alternation of the two filter sections, and the resting filter chamber 8 can be used directly without the need for manual replacement and unclogging of the filter plate 9, reducing manual intervention and effectively lowering labor intensity and maintenance costs.

[0053] Optionally, the cleaning unit 6 further includes two cleaning brushes 29 that abut against the bottom of the two filter plates 9 respectively, a control frame 30 that is movably mounted in the processing inner box 3 and whose two ends pass through the two filter chambers 8 respectively and are fixedly connected to the two cleaning brushes 29 respectively, and an electric push rod 31 installed in the processing inner box 3;

[0054] The telescopic end of the electric push rod 31 is fixedly connected to the control frame 30. While the cleaning pipe 22 in one of the filter chambers 8 sprays and cleans the filter plate 9 with several second spiral nozzles 23, the electric push rod 31 works to drive the control frame 30 to reciprocate horizontally in the processing inner box 3. This allows the two cleaning brushes 29 to clean the two filter plates 9 in the two filter chambers 8 at the same time. This ensures that the filter plates 9 in the filter chambers 8 can be cleaned to a certain extent during operation, effectively increasing the usable time. The cleaning effect of the filter plates 9 being sprayed and cleaned is effectively improved with the help of the cleaning brushes 29.

[0055] Optionally, the opening and closing part 7 includes a sealing ring 32 fixed inside the door body 10 and abutting against the inner wall of the filter chamber 8, and two limiting blocks 33 symmetrically rotated and mounted on the processing outer box 1, both abutting against the door body 10. When the door body 10 closes the filter chamber 8, the sealing ring 32 can effectively improve the airtightness of the filter chamber 8 and prevent exhaust gas leakage when the primary filtration part 2 is treating exhaust gas. By rotating the two limiting blocks 33, the movement of the door body 10 can be quickly limited and released, thus facilitating the quick maintenance and adjustment of the structure in the filter chamber 8 when needed.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
