[0024] The utility model provides a kind of ore sample analysis room multi-point acid mist interlocking collection processing system, it can be mainly used to the ore sample analysis room multi-point acid mist interlocking collection processing, such as: to the acid mist generated in the process of antimony gold mine analysis room sample dissolution is collected and handled.

[0025] As Figure 1 As shown in the utility model embodiment provided by the ore sample analysis room multi-point acid mist interlocking collection processing system includes the intercommunication processing device 10 and collection device 20, the collection device 20 includes collection pipeline 21 and multiple collectors 22 connected on the collection pipeline 21, the collector 22 is located above sample processing table, fan 23 is equipped on the collection pipeline 21 to flow to the collector 22 below acid mist into the processing device 10.

[0026] In this embodiment, during the large-scale processing of ore sample dissolution, the acid mist generated at multiple points can be collected into the processing device 10 through the collecting device 20, thereby achieving effective collection and centralized processing of the acid mist.

[0027] Specifically, the collection pipeline 21 includes a main pipeline 211 and a branch pipeline 212 connected to the main pipeline 211. The multiple collectors 22 are all connected to the branch pipeline 212. The branch pipeline 212 includes multiple sub-pipelines 213, and the sub-pipelines 213 are connected to the collectors 22 in a one-to-one correspondence. By providing multiple branch pipelines 212 and sub-pipelines 213, acid mist can be collected at multiple different points accordingly.

[0028] The branch lines 212 are each provided with a collecting branch line electromagnetic valve 214, and the sub-line 213 is each provided with a collecting sub-line electromagnetic valve 215. Therefore, the corresponding electromagnetic valves can be switched on and off according to demand to achieve collection at different points.

[0029] The treatment device 10 includes a treatment box 11 and a shelf 12 disposed within the treatment box 11. The top of the treatment box 11 is equipped with an exhaust pipe 13. The collection pipe 21 is connected to the bottom of the treatment box 11. A flow channel 14 is formed between the shelf 12 and the inner wall of the treatment box 11. Within the flow channel 14 are multiple acid mist absorbing layers 15, each containing multiple acid mist absorbing balls. In this embodiment, the flow channel 14 is generally S-shaped, which facilitates the absorption of acid mist during circulation. The treatment device 10 also includes a demisting layer 16 disposed above the flow channel 14 and a spray pipe 17 disposed on the flow channel 14, equipped with a spray pump. The neutralizing liquid sprayed through atomization and spraying ensures sufficient contact with the acid mist, thereby enhancing the acid mist absorption effect. It is understood that the acid mist absorbing balls can be conventional products, and the specific acid mist absorption principle and structure of the acid mist absorbing balls will not be elaborated here.

[0030] In addition, the treatment device 10 also includes a sewage discharge component arranged at the bottom of the treatment box 11, and the sewage discharge component includes a sewage discharge pipe 30 and a sewage discharge solenoid valve 40 arranged on the sewage discharge pipe 30. A hydroxide ion monitor 50 is provided on the sub-pipeline 213 and the treatment box 11. The hydroxide ion monitor 50 can detect the concentration of hydroxide ions in the solution. When the pH value exceeds the preset value, it can issue an alarm to replace the neutralizing liquid at the bottom of the treatment box 11, and discharge it through the sewage discharge pipe 30 by opening the sewage discharge solenoid valve 40. Among them, the hydroxide ion monitor 50 is an online pH detector, and the model can be LN-WA2 / LN-HB1, or other models of online pH detectors can be used. The detection principle and structure of the online pH detector are existing technologies and will not be repeated in this application.

[0031] In this application, a large amount of acid mist is generated during the sample dissolution operation at the sample processing station. At this time, the solenoid valve of the collection sub-pipeline is opened. The generated acid mist is collected by the acid mist collection hood above under negative pressure and then enters the sub-pipeline 213. When the hydroxide ion monitor 50 on the sub-pipeline 213 detects that the hydroxide ion concentration is lower than the preset hydroxide ion concentration for 10-15 consecutive minutes, the monitor sends a signal to the controller 90, which then provides a feedback signal to close the solenoid valve of the collection sub-pipeline. Similarly, the solenoid valve of the collection sub-pipeline sends a corresponding open or close signal based on the monitoring value of the hydroxide ion monitor 5022 of the collection sub-pipeline, realizing automatic control of the solenoid valve of the collection sub-pipeline.

[0032] Acid mist is introduced into treatment chamber 11 via blower 23. This blower 23, designed to take into account the effects of air volume and pressure, is integrally molded from plastic, enhancing its structural strength. A shock absorber is installed at the bottom of the plastic blower 23, and the inlet and outlet pipes are connected with a shock-absorbing flexible connection to reduce the impact of resonance between the plastic blower 23 and the pipes. The treatment chamber is a rectangular parallelepiped, with the air inlet and outlet flow channel 14 forming an overall S-shaped channel. The acid mist is absorbed twice, in reverse flow, and once in downstream flow, achieving an absorption efficiency exceeding 99%.

[0033] At the same time, the acid mist passes through the atomization layer and the acid mist absorption balls and is fully contacted with the neutralizing liquid sprayed from the spray atomizer by the spray pump through the spray pipe 17, achieving the effect of acid mist absorption. Finally, the treated exhaust gas passes through the W-shaped demisting layer 16 and the exhaust pipe 13 and is discharged in compliance with the standards. The spray pump delivers the circulating neutralizing liquid to the spray atomizers on each layer through the spray pipe, promoting full contact between the neutralizing liquid and the exhaust gas. The spray liquid forms droplets and flows to the surface of the acid mist absorption balls. The absorption liquid on the surface reacts with the exhaust gas again to neutralize. The neutralizing liquid flows to the atomization layer. The exhaust gas passes through the atomization layer and blows the liquid away to form small droplets again to react. The liquid on the inner wall of the tower flows to the bottom liquid storage tank for recycling.

[0034] The bottom of the spray tower is provided with 70 automatic water supplement pipes and electromagnetic valves, and liquid level control valves 80, which supplement in time when the neutralizing liquid level at the bottom of the treatment tank 11 drops.

[0035] The bottom of the treatment tank 11 is provided with a blowdown pipe 30 and a blowdown electromagnetic valve 40, which can send an alarm to replace the neutralizing liquid when the pH value exceeds the preset value according to the monitoring of the concentration of hydroxyl ions in the solution.

[0036] The fan 23 in the application is made of corrosion-resistant plastic in an integral form, and the fan 23 has no welding points. The fan 23 is provided with a damping spring at the bottom, and the air inlet and the air outlet of the fan 23 are connected to the pipeline in a soft connection mode. Therefore, the risk of acid mist leakage caused by oxidation and corrosion cracking at the welding points of the fan 23 can be avoided, the service life of the fan 23 is prolonged, the operation is stable, and resonance with the pipeline is avoided, which affects the service life of the pipeline.

[0037] The acid mist collection point can be flexibly adjusted according to actual needs, so that the equipment is convenient to disassemble and assemble, can be interchanged, the collecting cover is provided with an electric valve, the branch pipeline is provided with an acidity detector, the opening and closing of the electric valve of the collecting cover can be interlocked controlled according to the detection result of the acidity detector, the operation frequency of the fan 23 is automatically adjusted, the power consumption of the fan 23 is reduced, and the wind volume of the collection point is ensured.

[0038] The problems of unstable operation of the fan 23 and abnormal noise are effectively solved, the problems of insufficient air volume of the fire analysis chamber and the sample dissolving operation and mutual influence, small negative pressure of the tail gas collection point, and tail gas overflow are solved, the power consumption is reduced, the cost is saved, and the safety and environmental protection hidden dangers of the occupational health of the operating personnel and the surrounding environment are solved.
