[0002] In the coke oven production process, the raw gas produced by coking contains a lot of pollutants such as dust and tar. The main function of the traditional smoke guide car is to guide the raw gas produced by the carbonization chamber into the gas collecting pipe for subsequent treatment. However, in this process, due to the high temperature, high dust and complex working environment of the raw gas, it will not only cause environmental pollution, but also affect the normal operation and service life of the coke oven equipment.

[0003] The water seal cover plays a key sealing role in the exhaust gas treatment process connecting the dust removal and smoke guide vehicle with the carbonization chamber. In actual operation, smoke leakage is prone to occur at the water seal cover; if the water level in the water seal tank cannot be maintained at an appropriate height, for example, the water level drops due to evaporation, water replenishment system failure or water seal tank leakage, the sealing height of the water seal is insufficient and smoke leakage cannot be effectively prevented.

[0004] The existing water seal tank leakage treatment method is relatively simple, which only relies on the suction force of the smoke guide pipe to absorb the smoke, but it cannot treat the leaked exhaust gas on a large scale.

[0005] To this end, those skilled in the art have proposed a dust removal and smoke guiding vehicle with an onboard dust removal device to solve the problems raised by the background art. Summary of the invention

DETAILED DESCRIPTION

[0025] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] Embodiment 1: As shown in the attached Figure 2 To Attachment Figure 5 As shown: The present invention provides a dust removal and smoke guiding vehicle with an onboard dust removal device, comprising a dust removal and smoke guiding vehicle body 1 and a dust removal component 5:

[0027] As attached Figure 1 As shown: a smoke guide pipe lifting cylinder 2 is installed at the inner frame of the dust removal smoke guide vehicle body 1, and a lifting frame 3 is connected to the telescopic end of the smoke guide pipe lifting cylinder 2; a smoke guide pipe 4 is installed at the lifting frame 3, and the height change of the lifting frame 3 is controlled by the smoke guide pipe lifting cylinder 2, so as to drive the smoke guide pipe 4 to descend to the water seal cover of the carbonization chamber to perform the smoke guiding operation;

[0028] As attached Figure 2 and attached Figure 3As shown: the dust removal assembly 5 includes a first dust removal ring 501, a second dust removal ring 502 and a connecting pipe 6. The cross-sections of the first dust removal ring 501 and the second dust removal ring 502 are trapezoidal, and the bottom surfaces of the first dust removal ring 501 and the second dust removal ring 502 are both provided with connecting grooves 503. The first dust removal ring 501 and the second dust removal ring 502 are connected to the sides of the smoke guide pipe 4. The connecting pipe 6 is connected between the dust removal ring and the smoke guide pipe 4. The connecting pipe 6 has a curved pipe body structure. A first fan 601 is installed at one end of the connecting pipe 6. The first fan 601 is connected to the connecting groove 503. A second fan 601 is installed at the other end of the connecting pipe 6. The fan 602; the first dust removal ring 501 and the second dust removal ring 502 can be assembled in a split manner, so that the dust removal assembly 5 can be quickly assembled on the side of the smoke guide pipe 4, and the first fan 601 can quickly blow air in the connecting groove 503 to generate negative pressure at the bottom of the connecting groove 503, so that the smoke leaking from the water seal cover can be quickly led into the connecting pipe 6. Since the dust absorption range of the first dust removal ring 501 and the second dust removal ring 502 is larger than that of the smoke guide pipe 4, the leaked smoke can be stably absorbed; the second fan 602 allows the smoke to be stably conducted from the connecting pipe 6 to the smoke guide pipe 4;

[0029] The first dust removal ring 501 and the second dust removal ring 502 are trapezoidal in cross-section and are connected to the sides of the smoke duct 4. Their dust suction range is larger than that of the smoke duct 4. When smoke leakage occurs at the water seal cover, the leaked smoke can be captured in a larger area. Compared with relying solely on the suction force of the smoke duct, the collection efficiency of the leaked smoke is significantly improved, and the possibility of smoke escaping into the surrounding environment is reduced.

[0030] By using the first fan 601 at one end of the connecting pipe 6 to blow air into the connecting groove 503 to generate negative pressure, the smoke leaking from the water seal cover can be actively sucked into the connecting pipe 6. Compared with the traditional passive absorption that only relies on the suction of the smoke guide pipe, it can more effectively deal with leakage situations. Even when the smoke leakage is large or the leakage points are widely distributed, the smoke can be collected in time to prevent it from spreading and polluting the environment.

[0031] As attached Figure 3 and attached Figure 4 As shown: the filter assembly includes an inclined mounting plate 7 and a filter element 701, and the filter element 701 is an activated carbon filter layer; the filter element 701 is fixed to the inner cavity of the inclined mounting plate 7, and a mounting groove 603 is provided on the side of the connecting pipe 6, and the inclined mounting plate 7 is installed inside the mounting groove 603; when the smoke passes through the filter element 701, the smoke can be coarsely filtered, and due to the use of the inclined mounting plate 7, the smoke contact area is increased compared with the horizontal installation, thereby increasing the area for filtering the smoke within the limited size of the connecting pipe 6, and effectively filtering the leaked smoke.

[0032] The filter element 701 adopts an activated carbon filter layer, which can coarsely filter the flue gas when the flue gas inhaled from the connecting pipe 6 passes through; the activated carbon can absorb some harmful gases in the flue gas, such as sulfur dioxide, nitrogen oxides, tar, and fine dust and other pollutants, reduce the toxicity and pollution of the flue gas, further purify the collected flue gas, and reduce the adverse effects on subsequent equipment and the environment.

[0033] Compared with the horizontal installation method, the design of the inclined mounting plate 7 increases the contact area between the flue gas and the filter element 701 within the limited size of the connecting pipe 6; within the same filtering time, more flue gas can fully contact the filter element and be purified, thereby improving the filtration efficiency, making the treated flue gas more in line with environmental emission standards, and is conducive to improving the air quality around the coke oven.

[0034] A positioning assembly 8 for locking the position of the oblique mounting plate 7 is installed on the outer wall of the connecting pipe 6. The oblique mounting plate 7 can be quickly assembled and fixed by the positioning assembly 8, and can be manually disassembled quickly later;

[0035] As attached Figure 4 As shown: the positioning assembly 8 includes a positioning seat 801, a return spring 803, a clamping column 804 and a pull plate 805; the positioning seat 801 is fixed to the front end surface of the connecting pipe 6, the inner wall of the positioning seat 801 is provided with a stretching groove 802, the stretching groove 802 is connected to the mounting groove 603, the return spring 803 is connected to the inner wall of the stretching groove 802, one end of the return spring 803 is connected to the clamping column 804, the side wall of the inclined mounting plate 7 is provided with a positioning groove 703, the clamping column 804 is engaged with the positioning groove 703, the end of the clamping column 804 is a wedge-shaped surface, the side wall of the clamping column 804 is fixedly connected to the pull plate 805, and the pull plate 805 penetrates to the outer wall of the positioning seat 801;

[0036] When installing the oblique mounting plate 7, insert it into the mounting groove 603. During the insertion process, the wedge-shaped surface of the clamping column 804 is squeezed and pressed into the stretching groove 802. When the position of the positioning groove 703 is aligned with the stretching groove 802, the clamping column 804 loses resistance. At this time, the reset spring 803 quickly resets, and the clamping column 804 pops out and quickly snaps into the positioning groove 703. The oblique mounting plate 7 is effectively limited by the clamping column 804, thereby realizing the installation and fixation of the oblique mounting plate 7, and the fixed oblique mounting plate 7 has good stability.

[0037] When the filter element 701 needs to be removed for cleaning or replacement, the pull plate 805 is pulled to drive the clamping column 804 to move, and the clamping column 804 is pulled out from the positioning groove 703 to release the limit of the clamping column 804. At this time, the inclined mounting plate 7 is pulled out, and the filter element 701 can be quickly taken out for replacement, which greatly improves the installation and replacement efficiency.

[0038] The positioning assembly 8 realizes the quick installation and manual quick disassembly of the inclined mounting plate 7; the limit of the inclined mounting plate 7 by the clamping column 804 can be released by simply pulling the pull plate 805, so that the filter element 701 can be taken out for cleaning or replacement, which reduces the difficulty of filter element maintenance and ensures that the filter element can always maintain good filtering performance, prolongs the service life of the filter assembly, and reduces the operating cost of the equipment in the long run;

[0039] A handle 702 is fixedly connected to the outer wall of the inclined mounting plate 7, and the handle 702 can be used to more conveniently pull the inclined mounting plate 7.

[0040] From the above, we can see that Figure 1 When smoke guiding operation is required, the smoke guiding pipe lifting cylinder 2 starts to work, and its telescopic end drives the lifting frame 3 to adjust the height, so that the smoke guiding pipe 4 descends to the water seal cover of the carbonization chamber, and a smoke guiding channel is established to guide the raw coal gas generated in the carbonization chamber into the subsequent treatment system.

[0041] As attached Figure 5 As shown: when smoke leakage occurs at the water seal cover, the first fan 601 is started to blow air toward the connecting groove 503, so that negative pressure is generated at the bottom of the connecting groove 503. Since the dust suction range of the first dust removal ring 501 and the second dust removal ring 502 is larger than that of the smoke guide pipe 4, the leaked smoke is sucked into the connecting pipe 6 under the action of negative pressure; the second fan 602 works at the same time, and under the action of its suction force, the smoke sucked into the connecting pipe 6 is stably conducted to the smoke guide pipe 4, and then introduced into the subsequent treatment system together with the raw coal gas in the normal smoke guiding process, thereby realizing the collection and transfer of the smoke leaking at the water seal cover, and avoiding its direct discharge into the atmosphere to cause pollution.

[0042] When the smoke is transmitted in the connecting pipe 6 , it will pass through the filter assembly. The filter element 701 in the filter assembly is fixed in the inner cavity of the inclined mounting plate 7 , and the inclined mounting plate 7 is installed in the mounting groove 603 on the peripheral side of the connecting pipe 6 .

[0043] Due to the use of the inclined mounting plate 7, compared with horizontal installation, the contact area between the flue gas and the filter element 701 is increased, and the area for filtering the flue gas is effectively increased within the limited size of the connecting pipe 6. When the flue gas passes through the filter element 701, its activated carbon filter layer can coarsely filter the flue gas, remove some dust, harmful substances, etc., further purify the flue gas, and reduce pollution to subsequent equipment and the environment.

[0044] The inclined mounting plate 7 is fixed by the positioning assembly 8; the positioning seat 801 is fixed to the front end surface of the connecting pipe 6, and the stretching groove 802 on its inner wall is connected to the mounting groove 603. One end of the return spring 803 is connected to the inner wall of the stretching groove 802, and the other end is connected to the clamping column 804; the side wall of the inclined mounting plate 7 is provided with a positioning groove 703.

[0045] When installing the oblique mounting plate 7, it is inserted into the mounting groove 603. During the insertion process, the wedge-shaped surface of the clamping column 804 is squeezed and pressed into the stretching groove 802. When the positioning groove 703 is aligned with the stretching groove 802, the clamping column 804 pops out under the action of the return spring 803 and quickly snaps into the positioning groove 703, thereby installing and fixing the oblique mounting plate 7 and ensuring its stability during operation.

[0046] When the filter element 701 needs to be replaced or cleaned, pull the pull plate 805 to drive the clamping column 804 to move, so that it is pulled out from the positioning groove 703 to release the limit, and then the inclined mounting plate 7 is conveniently pulled out through the handle 702, and the filter element 701 can be quickly taken out for processing, which greatly improves the installation and replacement efficiency and facilitates the maintenance and maintenance of the equipment.

[0047] This dust removal device has many significant advantages in solving the problem of smoke treatment caused by water seal tank leakage, and can effectively improve the environmental protection level and equipment operation efficiency in the coke oven production process.

[0048] Embodiment 2: A guide portion 504 is fixed to the inner surface of the first dust removal ring 501 and the second dust removal ring 502 .

[0049] As can be seen from the above, the guide portion 504 plays a role in guiding the airflow when the smoke enters the dust removal ring, so that the smoke can enter the connecting groove 503 more smoothly, reducing the turbulence and resistance of the airflow, and improving the airflow stability during the dust collection process, so that the smoke can be more efficiently sucked into the connecting pipe 6, further improving the entire dust removal system's ability to handle smoke leakage at the water seal cover.

[0050] Embodiment 3: The first dust removal ring 501 and the second dust removal ring 502 are fixedly connected with connecting plates 9 at their outer walls, and a plurality of bolts 10 are threadedly engaged between the two sets of connecting plates 9 .

[0051] As can be seen from the above, the first dust removal ring 501 and the second dust removal ring 502 are connected and fixed at their outer walls by connecting plates 9 and bolts 10, so that the first dust removal ring 501 and the second dust removal ring 502 can be assembled in a split manner, which is convenient for rapid assembly and disassembly on the sides of the smoke guide pipe 4, and is convenient for the assembly, maintenance and component replacement of the equipment; the stable dust removal ring structure helps to maintain the normal performance of its dust collection and airflow guiding functions, reduce problems such as reduced smoke leakage treatment effect due to loose or deformed structure, and improve the reliability of equipment operation.
