Description

Technical Field

[0001] The utility model relates to the technical field of acid mist inhibitor processing, in particular to an acid mist inhibitor performance detection device. Background Art

[0002] Various additives are used in the production process of metal materials, such as explosion-proof agents, pickling additives, cleaning agents, cleaning powders, acid mist inhibitors, etc. Among them, acid mist inhibitors are mainly used in the metal acid leaching process. They can inhibit the acid mist generated by the acid leaching liquid, thereby reducing the negative impact of the acid mist on the surrounding environment and workers. After the production of acid mist inhibitors, samples need to be selected to test their performance to avoid the inhibition effect not meeting the standards, resulting in a large amount of acid mist generated during the acid leaching process, which will cause great harm to the environment and the health of the workers.

[0003] An acid mist suppressant performance detection device with application number 202220948957.9, this technical scheme absorbs the acid mist by setting up several absorption bottles, and measures the performance of the acid mist suppressant by subsequently testing the pH value of the absorption liquid. However, this technical scheme absorbs the acid mist by passing gas into the absorption liquid, and the gas flow rate is fast and the density is less than the absorption liquid, so that the gas rises quickly and separates from the absorption liquid, so that the contact time between the acid mist and the absorption liquid is short, so that acid mist still exists in the discharged waste gas, which is harmful to the performance detection accuracy of the acid mist suppressant and the environment and the health of the surrounding workers. This is also the reason why this technical scheme sets up several absorption bottles for step-by-step absorption, which leads to the need to subsequently test the liquids in several absorption bottles, increasing the workload of the workers. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an acid mist suppressant performance detection device to solve the technical problems mentioned in the above technical solution.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an acid mist suppressant performance detection device, comprising a device body and an absorption chamber, an absorption assembly is arranged on the top of the device body, and the absorption assembly comprises a motor, a fan blade is connected to the output end of the motor, a hollow shaft passes through one side of the top of the device body, and bevel gears are connected to one side of the fan blade and the outside of the hollow shaft, a rotating joint is connected to the top of the hollow shaft, a second guide plate is connected to the outer ring of the hollow shaft, and stirring blades are connected to the top and bottom of the second guide plate, and the first guide plate is connected to the inside of the absorption chamber.

[0006] By adopting the above technical solution, the motor drives the fan to rotate while driving the hollow shaft to rotate slowly through the meshing of two bevel gears. The slow rotation of the hollow shaft drives the second guide plate and the stirring blade to rotate. The residence time of the gas in the absorption liquid is extended by the arrangement of several first guide plates and second guide plates, so that the absorption liquid can have a longer time to fully absorb and neutralize the acid mist. At the same time, the absorption liquid is stirred by multiple stirring blades to make the concentration of the absorption liquid evenly distributed after absorption.

[0007] Furthermore, the top and bottom of the first guide plate and the second guide plate are both sloped.

[0008] By adopting the above technical solution, since the top and the bottom of the first guide plate and the second guide plate are both sloped, the absorption liquid is guided to reduce the residue when the waste absorption liquid is discharged.

[0009] Furthermore, four of the first guide plates and the second guide plates are provided, and the four first guide plates and the four second guide plates are alternately distributed.

[0010] By adopting the above technical solution, the residence time of the gas in the absorption liquid is prolonged by setting a plurality of first guide plates and second guide plates, so that the absorption liquid can have a longer time to fully absorb and neutralize the acid mist.

[0011] Furthermore, the diameter of the bevel gear outside the hollow shaft is larger than the diameter of the bevel gear on one side of the fan blade.

[0012] By adopting the above technical solution, since the diameter of the external bevel gear of the hollow shaft is larger than the diameter of the bevel gear on the fan blade side, the rotation speed of the hollow shaft is free from the rotation speed of the fan blade, thereby preventing the hollow shaft from being damaged due to the collision resistance between the stirring blade and the absorption liquid due to excessive rotation speed of the hollow shaft.

[0013] Furthermore, a through hole is formed on the top of the first guide plate, and the diameter of the through hole on the top of the first guide plate is larger than the diameter of the hollow shaft.

[0014] By adopting the above technical solution, a through hole larger than the diameter of the hollow shaft is opened on the top of the first guide plate, which can avoid affecting the rotation of the hollow shaft and facilitate the flow of gas and absorption liquid through the through hole.

[0015] Furthermore, a plurality of stirring blades are provided, and the plurality of stirring blades are respectively located at the top and bottom of the four second guide plates and distributed in a ring array.

[0016] By adopting the above technical solution, the absorption liquid is stirred by a plurality of stirring blades, so that the absorption liquid and the air flow flow relative to each other, and the concentration of the absorption liquid is evenly distributed after absorption.

[0017] Furthermore, a reaction chamber and an absorption chamber are respectively provided on both sides of the device body, and an exhaust port is provided on the top of the absorption chamber, and a bubbler is connected to one side of the reaction chamber, an axial flow fan is installed above the reaction chamber, and an air supply pipe is connected to the air outlet of the axial flow fan.

[0018] By adopting the above technical solution, the air flow enters the bubbler to generate bubbles in the mixed liquid, and then the bubbles contact with the mixed liquid to generate a mixed gas composed of a small amount of acid mist and air. Then the axial flow fan is started to send the mixed gas into the gas pipe. At this time, the mixed gas flows through the gas pipe, the rotary joint and the hollow shaft in sequence into the absorption chamber, so that the mixed gas contacts with the absorption liquid, and the absorption liquid is neutralized by the acid mist, thereby separating the acid mist from the air.

[0019] Furthermore, one end of the gas delivery pipe is connected to a rotary joint.

[0020] By adopting the above technical solution, the hollow shaft generates relative movement with the rotary joint while rotating, thereby preventing the air pipe from being twisted off by the rotating hollow shaft.

[0021] Furthermore, a first liquid inlet valve is installed on one side of the outer surface of the device body, a second liquid inlet valve is installed on the other side of the outer surface of the device body, a first liquid discharge valve is installed below the outer surface of the device body, and the first liquid inlet valve and the first liquid discharge valve are both connected to the reaction chamber, and a second liquid discharge valve is installed on one side of the bottom of the device body, and the second liquid inlet valve and the second liquid discharge valve are both connected to the absorption chamber.

[0022] By adopting the above technical solution, the staff inputs the mixed liquid of acid solution and acid mist inhibitor into the reaction chamber through the first liquid inlet valve, and at the same time, the staff inputs alkaline liquid as absorption liquid into the absorption chamber through the second liquid inlet valve. After the reaction is completed, the staff opens the first liquid discharge valve and the second liquid discharge valve to discharge the waste liquid in the reaction chamber and the absorption chamber.

[0023] Furthermore, a pH sensor is installed at the lower part of the absorption chamber.

[0024] By adopting the above technical solution, the pH value of the absorption liquid is monitored by a pH sensor, so that the staff can check the amount of acid mist generated and then determine the performance of the acid mist inhibitor.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] The utility model arranges the absorption component, and the motor drives the fan to rotate while driving the hollow shaft to rotate slowly through the meshing of two bevel gears. After the hollow shaft rotates slowly, it drives the second guide plate and the stirring blade to rotate. The arrangement of the first guide plates and the second guide plates prolongs the residence time of the gas in the absorption liquid, so that the absorption liquid can have a longer time to fully absorb and neutralize the acid mist. At the same time, the absorption liquid is stirred by the multiple stirring blades, so that the concentration of the absorption liquid is evenly distributed after absorption. The acid mist in the gas can be fully absorbed to improve the detection accuracy and reduce the harm to the outside world. At the same time, it is driven by the induced draft equipment to reduce the cost. BRIEF DESCRIPTION OF THE DRAWINGS
