[0002] Natural asphalt is formed from petroleum through long-term compression by the Earth's crust and gradual changes due to contact with air and water. It exists in a natural form and often contains a certain proportion of minerals. Asphalt requires melting equipment for processing during its production.

[0003] Chinese Patent CN210595934U discloses a melting device for natural asphalt processing, including a base, with an organic body fixedly connected to the top of the base, and an exhaust pipe connected to the top of the organic body. This invention, through the coordinated use of a base, organic body, exhaust pipe, fan, air guide pipe, purification tank, liquid inlet pipe, nozzle, liquid outlet pipe, filter screen, fixing rod, movable sleeve, brush, pull rod, protective block, limiting mechanism, outer shell, moving plate, spring, limiting rod, pull block, pull hole, limiting groove, through hole, sealing ring, sealing block, sealing groove, and guide plate, solves the problem that existing asphalt melting furnaces, which rely solely on simple filters for exhaust gas, easily lead to large amounts of toxic substances polluting the surrounding environment and health, and are inconvenient to clean. This natural asphalt processing melting device has the advantages of exhaust gas purification and easy filter cleaning, and is worthy of promotion.

[0004] However, the above technical solution has the following shortcomings: after the waste gas generated by melting is directly introduced into the treatment liquid, the viscous oil mist in the flue gas is easy to aggregate on the liquid surface to form scum, which covers the gas-liquid contact surface, reduces the mass transfer efficiency, and the immersion exhaust will increase the back pressure of the exhaust system, resulting in a significant increase in the energy consumption of the fan, which affects the practicality of the device. Utility Model Content

[0021] Example 1

[0022] like Figure 1 - Figure 4 As shown, the melting equipment for natural asphalt processing proposed in this embodiment includes a base 1 and a purification device; a melting furnace 2 and a purification tower 6 are provided on the base 1, and a jet seat 8 is provided inside the purification tower 6. Multiple nozzles 9 facing downward and with different directions are provided on the jet seat 8.

[0023] The purification device includes two spray assemblies installed inside the purification tower 6 and an adsorption filter 18 installed above the spray assemblies. The spray assembly includes a first spray frame 10 installed on the purification tower 6 and having a circular through hole, a second spray frame 11 installed above the first spray frame 10, a plurality of spray heads 14 installed on the first spray frame 10 and the second spray frame 11, a pump body 15 installed on the base 1, an inlet pipe 12 for connecting the pump body 15 and the first spray frame 10, and a branch pipe 13 installed on the inlet pipe 12 and connected to the second spray frame 11. The second spray frame 11 is located directly above the circular through hole and its projection in the vertical direction covers the circular through hole.

[0024] The purification tower 6 is equipped with an air inlet pipe 7 and a liquid extraction pipe 23. The air inlet pipe 7 is connected to the jet seat 8. The purification tower 6 is equipped with a first fixed frame 21, and the jet seat 8 is mounted on the first fixed frame 21. The purification tower 6 is equipped with a second fixed frame 22, and the second spray frame 11 is mounted on the second fixed frame 22. The air inlet pipe 7 is used to transport the pretreated gas to the jet seat 8. The liquid extraction pipe 23 is used to extract the mixed solution at the bottom of the purification tower 6 for treatment. The first fixed frame 21 and the second fixed frame 22 are used to fix the jet seat 8 and the second spray frame 11, respectively.

[0025] In this embodiment, after the flue gas enters the interior of the jet seat 8 through the air inlet pipe 7, it is ejected through multiple downward-facing nozzles 9 with different directions. Some of the gas reacts directly with the treatment liquid below, while some of the gas escapes upward from the bottom of the purification tower 6. At this time, the pump body 15 draws the treatment liquid and delivers it to the first spray frame 10 and the second spray frame 11 through the liquid inlet pipe 12 and the branch pipe 13, respectively. Then, it is sprayed downward through the spray head 14, so that the treatment liquid and the gas can come into contact and react. The structural design of the circular through hole on the first spray frame 10 and the position and size of the second spray frame 11 ensures that the gas can be fully contacted by the treatment liquid during the upward process. At the same time, the multi-layer spraying effect ensures the duration of gas purification treatment in the purification tower 6, thereby fully ensuring the treatment effect of the gas. It also avoids the problem of scum covering the gas-liquid contact surface and reducing mass transfer efficiency caused by the direct immersion gas conveying method, and also reduces the energy consumption of the air supply structure, which has good practicality.

[0026] Example 2

[0027] like Figure 1 As shown in the figure, the melting equipment for natural asphalt processing proposed in this embodiment, compared with the first embodiment, has a fan 3, a cyclone dust collector 4 and a cooler 5 on the base 1. The fan 3 is connected to the melting furnace 2 and the cyclone dust collector 4. The cyclone dust collector 4, the cooler 5 and the purification tower 6 are connected in sequence.

[0028] In this embodiment, the cyclone dust collector 4 is a CLT / A-6.5 model to remove larger particles from the flue gas, and the cooler 5 is a GLC-150 dry cooler to reduce the temperature of the flue gas. When the asphalt is melted in the melting furnace 2, the gas generated is transported by the fan 3 and the air guide system and passes through the cyclone dust collector 4 and the cooler 5 in sequence, and finally enters the purification tower 6 through the air inlet pipe 7 for subsequent treatment.

[0029] Example 3

[0030] like Figure 2 and Figure 4 As shown, the melting device for natural asphalt processing proposed in this embodiment, compared with the first embodiment, has a frame 17 on the adsorption filter 18, a support frame 16 on the purification tower 6, a positioning block 19 embedded in the support frame 16 on the frame 17, and a detachable top cover 20 on the top of the purification tower 6, with an insertion ring 24 embedded in the purification tower 6 on the top cover 20.

[0031] In this embodiment, the top of the purification tower 6 can be opened by hoisting and disassembling the top cover 20, so that the frame 17 can be disassembled and the adsorption filter element 18 can be removed from the support frame 16. The adsorption filter element 18 can then be cleaned or replaced. When reinstalling, the frame 17 can be conveniently positioned by the positioning block 19. Then the top cover 20 can be closed again, and the insertion ring 24 is used for positioning and reinforcement.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
