Description

Technical Field

[0001] The invention relates to the technical field of acid mist absorption, in particular to an automatic trigger type acid mist absorption device for environmental protection in a hot dip galvanizing workshop. Background Art

[0002] Hot-dip galvanizing is a processing method for coating the surface of an object. When workers galvanize the surface of an object, acid mist will be generated. If the acid mist is discharged directly, it will cause environmental pollution. Therefore, an acid mist absorption and purification device is needed to treat the acid mist before discharging it to reduce damage to the environment. The acid mist absorption and purification device includes an acid mist purification tower.

[0003] Currently, most of the acid mist treatment methods on the market use a spray device to mix the acid mist and water, allowing the solid particles in the acid mist to settle, and the gas will be discharged through the purification tower.

[0004] During the use of this type of treatment device, the purified acid mist waste gas meets the emission requirements of local emission standards, which are lower than the national emission standards. As a result, the exhausted gas contains a large amount of harmful substances, causing air pollution; secondly, the purification towers currently on the market have a relatively monotonous structure during operation, and simply allow the acid mist and water to mix, and cannot completely remove the acidic substances in the acid mist. Therefore, the gas discharged from the purification tower contains harmful substances.

[0005] Therefore, in order to avoid air pollution caused by gas discharge, we specially propose an automatic trigger acid mist absorption device for environmental protection in hot-dip galvanizing workshops. Summary of the invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 9 , the present invention provides a technical solution: An automatic trigger type acid mist absorption device for environmental protection in a hot dip galvanizing workshop comprises a protective shell 1, the interior of the protective shell 1 is a cavity structure, a mist inlet 102 is provided at the lower end of the protective shell 1, and the acid mist can enter the interior of the protective shell 1, and a mist outlet 103 is provided at the upper right end of the protective shell 1, and the acid mist can be discharged therefrom. Figure 2 and Figure 3 shown.

[0034] The lower end of the protective shell 1 is located at the outer corner of the mist inlet 102, and a pH sensor 101 is fixedly installed. The pH sensor 101 can detect the content of acidic substances in the air in real time. When the acid concentration in the air reaches a preset value, the subsequent device will operate (wherein, the workshop produces acid mist during the hot plating process, so the pH sensor 101 detects the acid mist produced in real time, and the pH sensor 101 needs to be debugged multiple times before use to ensure that the use of the pH sensor 101 can respond in time), a negative pressure machine 104 is fixedly installed on the front end face of the protective shell 1, and a first signal transceiver 105 is fixedly installed on the upper end face of the negative pressure machine 104, wherein the first signal transceiver 105 and the pH sensor 101 are electrically connected.

[0035] Therefore, during use, when the pH sensor 101 detects the generation of acid mist, it will transmit a signal to the first signal transceiver 105. At this time, the first signal transceiver 105 will allow the negative pressure machine 104 to operate. The negative pressure generated can allow the acid mist in the air to pass through the mist inlet 102 into the interior of the protective shell 1, and then be discharged from the mist outlet 103 to enter the next process.

[0036] A mixing box 201 is fixedly installed at the upper right end of the protective shell 1, and an ammonia inlet pipe 202 with a vertical turntable is fixedly installed on the upper end surface of the mixing box 201. The upper end of the ammonia inlet pipe 202 can be fixedly connected to an external pipeline, so that external ammonia can pass through the ammonia inlet pipe 202 and enter the interior of the mixing box 201. Figure 4 shown.

[0037] A second signal transceiver 203 is fixedly installed on the left side of the front end face of the mixing box 201, and a first motor 204 is fixedly installed on the upper end face of the mixing box 201 located on the left side of the ammonia inlet pipe 202, and a gear 205 is fixedly installed on the output shaft of the first motor 204, wherein a groove 206 of an annular structure is opened on the north side of the left side inside the mixing box 201, and a gear plate 207 is rotatably installed inside the groove 206, and a tooth groove is opened on the outer side surface of the gear plate 207, and the gear 205 passes through the mixing box 201 and meshes with the tooth groove.

[0038] Therefore, during use, the first motor 204 is started, and the output shaft of the first motor 204 will rotate with the gear 205. When the gear 205 rotates, it can drive the gear plate 207 to rotate inside the groove 206. Moreover, since the second signal transceiver 203 and the first motor 204 are electrically connected, the second signal transceiver 203 will rotate the first motor 204 after receiving the signal from the pH sensor 101.

[0039] A circular hole is opened and closed from the left side to the center of the right side of the gear plate 207 to allow the acid mist to pass through and enter the interior of the mixing box 201. The acid mist entering the mixing box 201 will enter the ammonia through the ammonia inlet pipe 202 for mixing.

[0040] A hexagonal groove 208 is provided on the left side of the gear plate 207. A slider is slidably mounted inside each straight side of the hexagonal groove 208, and a closing plate 209 is fixedly mounted on the left side of the slider. Figure 5 shown.

[0041] Then, a circular cylinder is fixedly installed at the center of the left side of the closing plate 209, and a chute slide plate 210 is evenly fixedly installed in a circular array on the left side of the mixing box 201, and the left side of the cylinder on the left side of the closing plate 209 is slidably installed on the chute slide plate 210, as shown in FIG. Figure 4 shown.

[0042] During use, the gear plate 207 will slide with the closing plate 209 under the action of the slider, and during the sliding process, the closing plate 209 will slide obliquely under the restriction of the cylindrical and inclined groove slide plate 210, so that the closing plate 209 can open the hole on the gear plate 207. It should be noted that the sliders on the right side of the closing plate 209 are all located at the corner position of its straight edge, so as to ensure the sliding effect of the closing plate 209.

[0043] After the acid mist and ammonia gas are mixed, they will enter the interior of the L-shaped pipe 401, wherein an annular water pipe 402 is fixedly installed at the upper end of the L-shaped pipe 401 near the left opening, and water spray pipes 403 are evenly fixedly installed in a circular array on the outer surface of the annular water pipe 402, and small water spray holes are opened on the outer surface of the water spray pipe 403 for spraying water.

[0044] Therefore, during use, the water pump 6 can allow the water source to pass through the delivery pipe 601 to be transported to the interior of the annular water pipe 402, and then the annular water pipe 402 is connected with each water spray pipe 403, so that the water source inside the annular water pipe 402 will enter the interior of the water spray pipe 403, and the water spray holes are evenly opened from the outer side to the inside of the water spray pipe 403, so the water source inside the water spray pipe 403 will pass through the water spray holes under the action of pressure and enter the interior of the L-shaped pipe 401.

[0045] At this time, due to the mixture of acid mist and ammonia, in the spraying water source, the substances in the acid mist will absorb the water source, so that the particles in the acid mist that are invisible to the naked eye can slowly gather together.

[0046] Condensation pipes 404 are evenly fixedly installed in a circular array in the inner interlayer at the right end of the L-shaped pipe 401, and a controller 405 is fixedly installed on the outer side of the lower end of the L-shaped pipe 401. Figure 6 shown.

[0047] During use, the controller 405 can make the condenser 404 operate, so that the temperature inside the lower end of the L-shaped pipe 401 can be in a relatively low state, so that the particles in the passing acid mist can be quickly liquefied to avoid self-liquefaction. In this case, the liquefaction speed is slow, affecting the effect of subsequent operations. Therefore, a lower temperature can liquefy the gas to obtain acid mist liquid, thereby improving operating efficiency.

[0048] The filter tower 501 in the filter assembly 5 is fixedly installed at the lower end of the L-shaped pipe 401, wherein a mounting hole 502 is opened from the front end to the inside of the filter tower 501, and the number of mounting holes 502 is three, and filter plates 503 are slidably installed inside the mounting holes 502, wherein the rear end of the filter plate 503 is combined with the inner wall of the filter tower 501, and a U-shaped handle is fixedly installed at the front end, so that personnel can easily inspect and replace the filter plate 503. Figure 7 shown.

[0049] During use, the liquefied acid mist will still be mixed with non-liquefiable impurities. Therefore, it is necessary to filter the non-liquefied impurities to ensure the subsequent filtering effect. Moreover, the apertures of the three filter plates 503 are very different. The top filter aperture is the largest, and the aperture decreases as it goes down, so as to cope with different impurities.

[0050] A separation box 507 is fixedly installed at the lower end of the filter tower 501, wherein the interior of the separation box 507 is a cavity structure, and a material port 514 is opened from the top to the interior for connecting with the filter tower 501, and then, an installation slide 508 is opened from the front end surface to the inner rear wall of the separation box 507, and a gravity plate 509 is slidably installed inside the installation slide 508, and the gravity plate 509 is used to block the material port 514, so that a space is formed between the lowest filter plate 503 and the gravity plate 509, such as Figure 7 shown.

[0051] At this time, the sodium hydroxide delivery pipe 504 on the left side of the filter tower 501 can transport the external sodium hydroxide to between the bottom filter plate 503 and the gravity plate 509, so that the liquefied liquid and the sodium hydroxide can be mixed. During the mixing operation, the second motor 505 on the rear end of the filter tower 501 can be operated, and the output shaft of the second motor 505 rotates synchronously with the stirring teeth 506. The stirring teeth 506 can fully mix the liquid and the sodium hydroxide, so that a chemical reaction can occur. The reaction formula is: The products after the reaction are sodium chloride and water. Under the action of chemical materials, the acid mist eventually turns into solid and water without producing any smoke, so that the device will not emit any smoke, thereby ensuring the freshness of the air.

[0052] Telescopic cylinders 510 are fixedly installed on both sides of the upper end surface of the separation box 507, and the telescopic rods of the telescopic cylinders 510 are fixedly connected to the front end surface of the gravity plate 509. At this time, the telescopic rod of the telescopic cylinder 510 slides the gravity plate 509 to the front end, so that sodium chloride and water can pass through the material port 514 and enter the interior of the separation box 507.

[0053] A diaphragm 513 is slidably installed inside the separation box 507, and a mounting frame 512 is fixedly installed on the outside of the diaphragm 513. The front end surface of the separation box 507 is located below the mounting groove 508 and is provided with a through hole 511. The mounting frame 512 is slidably installed inside the through hole 511, and the rear end surface inside the separation box 507 is in a recessed state for receiving the rear end edge of the mounting frame 512 to prevent the rear end of the mounting frame 512 from tilting downward, thereby ensuring that the mounting frame 512 is in a horizontal state.

[0054] At this time, the sodium chloride and water will be in a separated state under the action of the diaphragm 513, and the sodium chloride will stay on the upper surface of the diaphragm 513, while the water will pass through the diaphragm 513 and be inside the separation box 507, and the water pump 6 and the inside of the separation box 507 are in a connected state. Therefore, the water will enter the delivery pipe 601 under the action of the water pump 6, and finally enter the annular water pipe 402 to spray the acid mist. It should be noted that during use, in order to avoid insufficient water source, the water pump 6 can also be connected to other water sources in the outside world to ensure sufficient water source, and the water source knowledge resource inside the separation box 507 is secondary utilized and is not used as the main water source point. In addition, during use, the height of the installation frame 512 is higher than the diaphragm 513, so as to avoid the installation frame 512 sliding out of the separation box 507 with the diaphragm 513, and the sodium chloride on the surface of the diaphragm 513 will not be blocked by the through hole 511, thereby ensuring that the sodium chloride is smoothly taken out of the separation box 507.

[0055] Working principle: First, the pH sensor 101 operates, and under the action of the first signal transceiver 105, the negative pressure machine 104 operates, and the acid mist passes through the mist inlet 102, then passes through the mist outlet 103, and is then discharged from the mist outlet 103 to enter the next process.

[0056] The second signal transceiver 203 is in operation, the output shaft of the first motor 204 drives the gear 205 to rotate, the gear 205 drives the gear plate 207 to rotate, and the gear plate 207 drives the closing plate 209 to rotate, so that the acid mist enters the interior of the mixing box 201, and the ammonia in the ammonia inlet pipe 202 enters the interior of the mixing box 201 and mixes with the acid mist.

[0057] The acid mist enters the interior of the L-shaped pipe 401, and the water source sprays it. The condenser 404 keeps the interior of the lower end of the L-shaped pipe 401 in a low temperature state to liquefy the acid mist.

[0058] The liquefied liquid passes through the filter plate 503 and finally reacts with the sodium hydroxide to form sodium chloride and water. The sodium chloride is taken out of the separation box 507 under the action of the installation frame 512 and the diaphragm 513, and the water is reused under the action of the water pump 6.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
