Description

Technical Field

[0001] This utility model belongs to the field of non-ferrous metal smelting technology, specifically, it relates to a water-cleaning blade flue gas dust collector. Background Technology

[0002] Due to the complex composition of impurities in the mixed ores, the flue gas produced from smelting contains a significantly higher level of heavy metals such as arsenic. This flue gas containing heavy metals poses a serious challenge to subsequent acid production processes.

[0003] In the existing acid production process, smelting flue gas needs to undergo pre-treatment. However, some dust still enters the electrostatic precipitator (ESP) after treatment. The ESP is a crucial piece of equipment for further purifying the flue gas and removing fine particles and acid mist, but the large amount of dust containing heavy metals entering it gradually causes blockages. Once the ESP is blocked, it must be shut down for cleaning. This not only disrupts the normal production schedule, causing a complete production stoppage, but also prevents the annual production target from being met, severely impacting the company's production and economic efficiency.

[0004] From a technological perspective, adjusting the impurity content of the ore and reducing the use of ores with high impurity content is an ideal solution. However, in practice, changing the ore source faces numerous difficulties. Therefore, changing the ore source through technological means is difficult to achieve quickly under the current circumstances. Enterprises can only turn their attention to equipment improvement, hoping to take effective measures in the purification unit at the front end of the acid production plant to block heavy metals from entering the electrostatic precipitator, thereby ensuring the normal operation of production.

[0005] A thorough analysis of the acid production flue gas purification process reveals that while most of the mineral dust is effectively removed after entering the acid production purification stage, a small portion of the dust and heavy metals such as arsenic trioxide remain, binding with water droplets to form fine particles. More importantly, these heavy metals, including arsenic, are also tightly bound to the water droplets in an ionic state. Because these fine particles and ionic heavy metal droplets are extremely light, existing purification devices, which primarily rely on gravity for gas-liquid separation, are clearly insufficient. Therefore, these fine droplets remain in the acid production gas and enter the electrostatic precipitator along with the flue gas.

[0006] When flue gas enters the electrostatic precipitator, environmental conditions change. The flue gas velocity decreases to 0.8 m / s, and the temperature ranges from 35 to 38°C. Under these relatively low temperature and velocity conditions, heavy metals contained in the small droplets begin to crystallize and precipitate. Under the influence of the electric field, these heavy metal crystalline dust particles move towards the anode and adhere to its surface. Because the adhesion force of these small particles is greater than their own weight and inertia, once they reach the anode surface, they will remain adhered to the anode tube for a long period. Simultaneously, some heavy metal crystalline dust particles also adhere directly to the cathode wire. Over time, these heavy metal crystalline dust particles adhered to the cathode wire and anode tube accumulate, eventually causing the electrostatic precipitator to become clogged and unable to operate normally.

[0007] In contrast, at the flue gas outlet of the purification intercooler tower, the flue gas temperature is 39–42°C, and the flow velocity reaches 2.065 m / s. Under these conditions, the fine mineral dust and small droplets in the flue gas have not yet reached the conditions for crystallization and precipitation, and therefore can operate normally with the flue gas without immediately causing blockage to the equipment. This demonstrates that flue gas temperature and flow velocity are important factors affecting the crystallization and adhesion of heavy metal droplets to the electrostatic precipitator.

[0008] Based on the above in-depth analysis of the existing acid production process and equipment operation, in order to effectively solve the problem of production being affected by the blockage of electrostatic precipitators due to heavy metal dust, it is necessary to design a new type of water-cleaning blade flue gas dust collector.

[0009] In view of this, this utility model is proposed. Utility Model Content

The flue gas is then sprayed and cooled by the cooling water spray nozzles 12. The flue gas dust removal tower 11 is the last line of defense for removing polymers from the flue gas. After the flue gas has been cooled multiple times, if there are still polymers remaining after the dust collector blades 31 remove dust, most of them will adhere to the flue gas dust removal tower 11 after passing through the 500 mm flue gas dust removal tower 11. The flue gas dust removal tower 11 can then be disassembled and cleaned.

[0040] Specifically, such as Figure 1 As shown, a dust collector top cover 23 is fixedly installed on the top of the dust collector tower body 10.

[0042] When the flue gas enters the flue gas dust removal tower 11, its temperature is around 35℃. It is necessary to cool the flue gas with ambient temperature water (approximately 20℃). Cooling is achieved by fully opening all ten sets of cooling water spray nozzles 12. Temperature and flow rates are monitored using the temperature and flow controller 13. If the temperature is below 30℃ on the tower support rod and the flue gas flow rate is the same as that of the intermediate cooling tower, the operation is normal. If the temperature is too high or too low, the water flow rate should be adjusted. The tower support rod 30 is entirely made of 450H steel and is externally painted for corrosion protection.

[0043] Based on the above, the structure of the dust collector body 10, flue gas dust removal tower 11, cooling water spray nozzle 12, temperature and flow controller 13, cooling water inlet 14, cooling water regulating valve 15, water supply pipe 16, flue gas inlet 17, polypropylene filter material 20, maintenance manhole 21, flue gas outlet pipe 22, dust collector top cover 23, safety fence 24, ladder 25, slag and water storage hopper 26, slag discharge water pipe 27, regulating valve 28, slag discharge water outlet 29, and tower support rod 30 achieves the purpose of transporting and cooling flue gas, facilitating maintenance personnel to inspect the equipment and discharge waste liquid, thus improving the convenience of using the equipment.

Flue gas is sprayed and treated through multiple sets of spray nozzles 46 at different angles.

[0045] In summary, the structure of the dust removal tower body 10, the water distribution main pipe 45, the spray nozzles 46, and the second inner fixing ring 48 achieves the purpose of fully spraying the flue gas, allowing the flue gas to react fully, improving the flue gas purification efficiency, and optimizing the user experience of the device.

[0046] Working principle: The dust collector consists of a dust collection tower body 10 and a dust collection structure. The dust collection tower body 10 is tank-shaped, and the dust collection structure includes a first dust collection section and a second dust collection section. After the flue gas enters the dust removal tower body 10, it passes through the first dust removal section and the second dust removal section in sequence for dust removal and purification. An opening is opened on one side of the outer wall of the dust removal tower body 10, and a flue gas dust removal tower 11 is fixedly installed in the opening.

A temperature and flow controller 13 is fixedly installed inside the flue gas dust removal tower 11. The flue gas enters the flue gas dust removal tower 11 through the flue gas inlet 17. When the cooling water regulating valve 15 is opened, the cooling spray water is delivered to the inside of the water supply pipe 16 through the cooling water inlet 14 and sprayed onto the flue gas for cooling through the cooling water spray nozzles 12. The flue gas dust removal tower 11 is the last line of defense for removing polymers from the flue gas. After the flue gas has undergone multiple cooling cycles and dust removal by the dust collector blades 31, if any polymers remain, most of them will adhere to the 500mm flue gas dust removal tower 11 after passing through it. The tower can then be disassembled and cleaned. Temperature and flow are monitored using the temperature and flow controller 13. If the temperature is below 30℃ and the flue gas flow is the same as that of the intermediate cooling tower, the operation is normal. If the temperature is too high or too low, the water flow should be adjusted. When the flue gas enters the flue gas dust removal tower 11, its temperature is around 35°C. It needs to be cooled with room temperature water (approximately 20°C). Cooling is achieved by fully opening ten sets of cooling water spray nozzles 12.
