By setting a collection component, the particulate impurities can be flexibly disassembled and collected, and it is convenient to clean.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] 1. This utility model is equipped with a collection component. By embedding the fitting ring of the combination ring with the inner side of the connecting pipe and the collection cylinder, it can be spliced. After splicing, the combination screw with only a semi-cylindrical shape is combined.

[0024] Please see Figure 1-4 A flue gas purification device for a precious metal pyrolysis furnace includes a cyclone dust collector 1.

[0025] The collection assembly includes a filter cylinder 2, and a combination ring 203 is fixedly installed at the top and bottom of the filter cylinder 2. A connecting pipe 201 is spliced ​​at the top of the combination ring 203, and a collection cylinder 206 is spliced ​​at the bottom of the combination ring 203. Four sets of combination screws 204 are welded and installed on the outside of the contact area of ​​the combination ring 203, the connecting pipe 201 and the collection cylinder 206. A limit nut 205 is movably installed on the outside of the combination screws 204.

[0026] The cooling mixing assembly includes a mixing cylinder 5, which is welded to the outside of the cyclone dust collector 1. A thin tube 403 is embedded and welded to the back of the lower end of the mixing cylinder 5, and an annular tube 404 is installed at the end of the thin tube 403. Several sets of aeration nozzles 405 are fixedly installed on the top of the annular tube 404. The mixing cylinder 5 stores a low-temperature mixed liquid 504 inside.

[0027] Through the above technical solution, the splicing can be assisted by embedding the fitting ring 202 of the combination ring 203 into the inner side of the connecting pipe 201 and the collecting cylinder 206. After splicing, the combination screw 204, which is only a semi-cylindrical, is combined. After the combination, the splicing is restricted by the limiting nut 205, thereby achieving quick disassembly and installation of the bottom collecting structure. The filter cylinder 2 can be used to export the generated gas, while the metal collecting cylinder 206 at the bottom can collect dust and impurities for easy cleaning.

[0028] Through the above technical solution, the mixing cylinder 5 can be used to carry the cooling liquid 504, and the liquid 504 is in close contact with the outer wall of the cyclone dust collector 1, which can cool the flue gas inside to a certain extent. At the same time, the annular pipe 404 injected into the inside can inject the flue gas after filtration into the liquid 504 through the aeration nozzle 405 for uniform mixing, thereby improving the processing efficiency.

[0029] Specifically, a flue gas inlet pipe 101 is fixedly installed on the front of the upper end of the cyclone dust collector 1, and a discharge valve 102 is fixedly installed at the bottom of the cyclone dust collector 1. The discharge valve 102 is welded and fixed to the connecting pipe 201, and an exhaust pipe 103 is embedded and fixedly installed at the top of the cyclone dust collector 1.

[0030] Through the above technical solution, the flue gas inlet pipe 101 is used to connect with the exhaust pipe 103 of the pyrolysis furnace, the unloading valve 102 is of type YJD-H, which can assist the cyclone dust collector 1 in exhaust separation, the cyclone dust collector 1 is of type XLP / B, and the exhaust pipe 103 can discharge the waste gas after the internal separation of impurity particles.

[0031] Specifically, a fitting ring 202 is fixedly installed at the end of the combined ring 203 away from the filter cylinder 2, and the fitting ring 202 is embedded in the inner side of the connecting pipe 201 and the collecting cylinder 206. The combined screw 204 is half the size of a normal screw.

[0032] Through the above technical solution, the interlocking ring 202 increases the stability of splicing by combination, and the combination can also increase the sealing performance.

[0033] Specifically, an impact-resistant filter element 302 is assembled on the back side of the end of the exhaust pipe 103 away from the cyclone dust collector 1. A movable sleeve 3 is separately arranged on the outer side of the impact-resistant filter element 302, and a splicing ring 301 is fixedly installed on the front side of the movable sleeve 3 by bolts. The splicing ring 301 is located on the front side of the disc-shaped structure welded at the end of the exhaust pipe 103.

[0034] Through the above technical solution, the impact-resistant filter element 302 is a metal filter structure, which can further filter the smoke and dust. The splicing ring 301 can be fixed to the movable sleeve 3 by bolt structure, and continuously squeeze the disc structure to increase the sealing performance.

[0035] Specifically, a transmission pipe 401 is embedded in the back side of the inner side of the movable sleeve 3, and an industrial vacuum cleaner 4 is installed on the back side of the transmission pipe 401.

[0036] Through the above technical solution, the transmission pipe 401 can guide the exhaust gas, and the filtered exhaust gas will not damage the interior of the industrial vacuum cleaner fan 4.

[0037] Specifically, the front of the industrial vacuum cleaner fan 4 is fixedly connected to the thin tube 403, and the input end of the industrial vacuum cleaner fan 4 is fixedly installed with a drive motor 402.

[0038] Through the above technical solution, the drive motor 402 can drive the industrial vacuum cleaner fan 4 to connect when it is powered on. The drive motor 402 needs to be connected to the external control equipment. The device can be configured and adjusted through a unified control device. The drive motor 402 needs to be connected to the external fixed structure through the bracket structure to ensure stability.

[0039] Specifically, a fixing ring 501 is welded and installed on the outer side of the lower end of the mixing cylinder 5, and an inlet pipe 502 is embedded in the front of the lower end of the mixing cylinder 5. A drain pipe 503 is installed on the back of the upper end of the mixing cylinder 5, and a discharge pipe 505 is provided on the right side of the upper end of the mixing cylinder 5.

[0040] Through the above technical solution, the fixing ring 501 can be connected to the external fixing area through the bolt structure, thereby achieving the effect of supporting the cyclone dust collector 1. The liquid inlet pipe 502 can be connected to the external cooling device to ensure normal delivery of the mixed liquid 504 for reacting and treating the waste gas. The low temperature of the reaction liquid will not change the reaction effect. The liquid outlet pipe 503 is used to inject liquid for addition, and the discharge pipe 505 can discharge the purified gas inside.

[0041] In use, the industrial vacuum cleaner 4 first uses the cyclone dust collector 1 to separate the particles from the exhaust gas. With the help of the discharge valve 102, the particulate impurities are collected inside the collection cylinder 206. The exhaust gas will then enter the impact-resistant filter element 302 through the exhaust pipe 103 for secondary filtration. The filtered exhaust gas will enter the annular pipe 404 through the transmission pipe 401 and the fine pipe 403. The aeration nozzle 405 sprays the gas to react with the mixed liquid 504. Finally, the exhaust gas will be discharged through the discharge pipe 505. While the reaction is taking place, the liquid inlet pipe 502 will continuously inject the low-temperature mixed liquid 504. When it is necessary to disassemble the collection cylinder 206, simply remove the limit nut 205 to disassemble and clean the bottom collection cylinder 206.
