Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to waste gas treatment equipment. Background Art

[0002] A large amount of waste gas is often generated during the waste disposal process. The waste gas often contains a lot of dust and harmful gases. Some existing waste gas purification devices use fans to introduce waste gas into water and use water to eliminate dust. However, in order to increase the processing speed, larger bubbles will be generated in the water, resulting in limited contact between waste gas and water. Aeration methods, such as microporous aeration and micro-nano aeration, can increase the contact between waste gas and water. However, due to the small aeration holes of the aeration tube, it is easy to get clogged, which increases the processing energy consumption and requires frequent replacement of the aeration tube. Some waste gas purification devices increase the solubility of waste gas in water by adding surfactants to water, thereby improving the waste gas processing capacity. However, surfactants are prone to secondary pollution. Filters filter haze air, which has high requirements on filter materials.

[0033] The following is combined with Figure 1-7 , the specific implementation of the present invention is described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific implementation. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] The waste gas treatment equipment provided by the present invention includes a fixed platform 21, a bubble breaking net 22, a driving component and an air duct 3. The fixed platform 21 is connected to the first treatment chamber 1. The top of the first treatment chamber 1 is provided with an air outlet 41. The middle part of the fixed platform 21 is provided with a through hole 211. The bubble breaking net 22 is annular and coaxial with the through hole 211. The diameter of the bubble breaking net 22 is greater than or equal to the diameter of the through hole 211. The bubble breaking net 22 is connected to the bottom of the fixed platform 21, and the top of the bubble breaking net 22 is flush with the bottom surface of the fixed platform 21, and the bottom is flush with the bottom surface of the first treatment chamber 1. The driving component is connected to the bubble breaking net 22, and is used to drive the bubble breaking net 22 to rotate around its own axis. The air duct 3 extends from the outside of the first treatment chamber 1 into the first treatment chamber 1, and is connected to the through hole 211 through the top of the through hole 211;

[0036] By adopting the above technical solution, the exhaust gas to be treated is guided directly through the through hole 211 to the bottom of the fixed platform 21 and the inner side of the bubble breaking net 22 by the air guide pipe 3, so that the exhaust gas is purified by the purification liquid in the first treatment chamber 1;

[0037] Due to the shielding of the fixing platform 21 and the existence of the bubble breaking net 22, the exhaust gas can only pass through the small holes of the bubble breaking net 22 and then be broken into small bubbles, thereby increasing the contact degree between the exhaust gas and the purification liquid, so that the exhaust gas and the purification liquid are fully in contact and fully reacted;

[0038] At the same time, the bubble breaking net 22 can be driven to rotate by the driving component, thereby further reducing the volume of a single exhaust gas bubble, increasing the contact degree between the exhaust gas and the purification liquid, and improving the reaction speed between the exhaust gas and the purification liquid;

[0039] Moreover, due to the rotation of the bubble breaking net 22, dust in the exhaust gas or solid matter insoluble in the solvent of the purification liquid generated after the exhaust gas reacts with the purification liquid is not easily adhered to the bubble breaking net 22, thereby avoiding blockage, eliminating or reducing the number of manual maintenance, and reducing labor and material costs;

[0040] The present invention has a simple method for treating waste gas, does not generate secondary pollution, and does not cause blockage. It can fully and evenly disperse dust-containing air or waste gas into microbubbles in the liquid, thereby increasing the contact degree between the dust and waste gas and the liquid.

[0041] As a preferred embodiment, a cleaning brush 5 is further connected to the first treatment chamber 1, and the cleaning brush 5 is located on the inner side of the bubble breaking net 22, and the brush surface of the cleaning brush 5 is in contact with the inner side of the bubble breaking net 22;

[0042] The cleaning brush 5 is in contact with the inner side of the bubble breaking net 22. When the bubble breaking net 22 rotates, the cleaning brush 5 and the bubble breaking net 22 rotate relative to each other, so that the cleaning brush 5 can clean up the dust in the exhaust gas that may adhere to the bubble breaking net 22 or the solid matter that is insoluble in the solvent of the purification liquid produced after the exhaust gas reacts with the purification liquid, thereby further avoiding the clogging of the bubble breaking net 22.

[0043] As a preferred embodiment, the bubble-breaking net 22 and the cleaning brush 5 are both provided with multiple, and the bubble-breaking net 22 and the cleaning brush 5 can be provided with two, three, four or more. In the present embodiment, the number of the bubble-breaking nets 22 and the cleaning brush 5 are both set to three, and each bubble-breaking net 22 is concentrically arranged below the fixed platform 21. The diameter of each bubble-breaking net 22 increases successively. The first cleaning brush 5 is arranged on the inner side of the first bubble-breaking net 22 from the inside to the outside, the second cleaning brush 5 is arranged between the first bubble-breaking net 22 and the second bubble-breaking net 22, and the third cleaning brush 5 is arranged between the second bubble-breaking net 22 and the third bubble-breaking net 22, and the brush handle of the first cleaning brush 5 is fixedly connected to the bottom wall of the first treatment chamber 1, the brush surface is in contact with the inner side of the first bubble-breaking net 22, and the second cleaning brush 5 is in contact with the inner side of the second bubble-breaking net 22. The brush handle of the sweeping brush 5 is fixedly connected to the outer side of the first bubble-breaking net 22, and the brush surface contacts the inner side of the second bubble-breaking net 22; the brush handle of the third cleaning brush 5 is fixedly connected to the outer side of the second bubble-breaking net 22, and the brush surface contacts the inner side of the third bubble-breaking net 22; it can also be that the brush handle of the first cleaning brush 5 is fixedly connected to the bottom wall of the first disposal chamber 1, and the brush surface contacts the inner side of the first bubble-breaking net 22; the second cleaning brush 5 is located between the first bubble-breaking net 22 and the second bubble-breaking net 22, and the brush handle is fixedly connected to the bottom wall of the first disposal chamber 1, and the brush surface contacts the inner side of the second bubble-breaking net 22; the third cleaning brush 5 is located between the second bubble-breaking net 22 and the third bubble-breaking net 22, and the brush handle is fixedly connected to the bottom wall of the first disposal chamber 1, and the brush surface contacts the inner side of the third bubble-breaking net 22;

[0044] The driving assembly is used to make any bubble breaking net 22 rotate around its own axis. A gear transmission assembly is connected between each bubble breaking net 22 to transmit the rotation of the bubble breaking net 22 to all bubble breaking nets 22. The rotation direction or angular velocity of any bubble breaking net 22 is different. Specifically, in this embodiment, the driving assembly includes a driving motor 83, and the driving motor 83 is installed in the bottom wall of the bottom wall of the first treatment chamber 1. The output shaft of the driving motor 83 extends upward from the bottom wall of the bottom wall of the first treatment chamber 1 and is coaxially arranged with the bubble breaking net 22. The driving motor 83 is electrically connected to the power supply, and the fixing platform Three ring gears 91 are coaxially connected to the inner surface of the fixed platform 21, and the three ring gears 91 correspond to each bubble breaking net 22 one by one. The diameter of each ring gear 91 is the same as that of the corresponding bubble breaking net 22, and each ring gear 91 is coaxially fixedly connected to the top of the corresponding bubble breaking net 22. The inner and outer sides of the ring gear 91 located in the middle are provided with meshing teeth. Each ring gear 91 is connected by a transmission gear 92, and the transmission gears 92 are rotatably connected to the fixed platform 21. The output shaft of the driving motor 83 is fixedly connected to the innermost ring gear 91 through a connecting rod.

[0045] The output shaft of the driving motor 83 can rotate the innermost ring gear 91 and drive the corresponding bubble breaking net 22 to rotate. At the same time, the transmission gear 92 drives the ring gears 91 to rotate at the same time, so that the bubble breaking nets 22 can be driven to rotate at the same time. Since the linear speeds of the transmission gears 92 and the ring gears 91 are consistent, and the diameters of the ring gears 91 are different, the angular speeds of the rotation of the bubble breaking nets 22 are different.

[0046] By adopting the above technical scheme, the exhaust gas entering the first treatment chamber 1 can be subjected to multi-stage defoaming through the multi-layered defoaming nets 22, thereby greatly increasing the contact degree between the exhaust gas and the purification liquid and improving the purification efficiency of the exhaust gas. At the same time, due to the different angular velocities of each defoaming net 22, there will be relative rotation between each defoaming net 22 and the cleaning brush 5 in contact with its inner side, so that the dust in the exhaust gas or the solid matter insoluble in the solvent of the purification liquid produced after the exhaust gas reacts with the purification liquid can be cleaned by the brush surface of the cleaning brush 5 in contact with its inner side, thereby avoiding clogging of the defoaming net 22.

[0047] As a preferred mode, an annular boss 11 is provided at the bottom of the first treatment chamber 1, the annular boss 11 is coaxial with the bubble breaking net 22, the diameter of the annular boss 11 is adapted to the bubble breaking net 22, the bottom end of the bubble breaking net 22 is flush with the top surface of the annular boss 11, and the cross section of the annular boss 11 is an isosceles trapezoid. Specifically, a waste liquid discharge outlet is provided at the bottom of the first treatment chamber 1, inside the innermost annular boss 11, between the annular bosses 11, and outside the outermost annular boss 11, and a solenoid valve 13 is provided in each waste liquid discharge outlet, and the solenoid valve 13 is electrically connected to a power supply;

[0048] By adopting the above technical solution, the dust in the exhaust gas brushed off from the bubble breaking net 22 or the solid matter insoluble in the solvent of the purification liquid produced after the exhaust gas reacts with the purification liquid will fall on the inner side of the innermost annular boss 11 or between the annular bosses 11, thereby avoiding the above solid matter from accumulating on the inner side of the bubble breaking net 22 and causing blockage. Then, by opening the solenoid valve 13, all the waste liquid and waste residue can be discharged after the exhaust gas purification is completed.

[0049] As a preferred mode, the top of the first treatment chamber 1 is connected with the second treatment chamber 61, the top of the second treatment chamber 61 is connected with the first treatment chamber 1 through the air outlet 41, and the bottom is provided with an exhaust port 42. A plurality of connecting holes are provided on the inner wall of the second treatment chamber 61, and the purified liquid is also poured into the liquid storage chamber 62. An overflow valve 64 is provided in each of the connecting holes. The end of the overflow valve 64 close to the second treatment chamber 61 is the outlet end, and the end close to the liquid storage chamber 62 is the inlet end. A plurality of liquid absorbing nets 63 are provided in the second treatment chamber 61, and each liquid absorbing net 63 is horizontally arranged in the second treatment chamber 61 in sequence along the vertical direction. A liquid absorbing end is provided on the liquid absorbing net 63, and the liquid absorbing net 63 is connected to the outlet end of the connecting hole through the liquid absorbing end. Specifically, the liquid absorbing net 63 can be a sponge net layer or a cotton net layer with good water absorption, and each liquid absorbing net 63 can also be an integral sponge body;

[0050] The purified liquid in the liquid storage chamber 62 has a certain hydraulic pressure, which can open the overflow valve 64, so as to penetrate into the liquid absorbing end of the liquid absorbing net 63 in the second treatment chamber 61 through the connecting hole, and gradually penetrate into the entire liquid absorbing net 63. After the exhaust gas is purified once in the first treatment chamber 1, it enters the second treatment chamber 61 from the gas outlet 41, passes through the liquid absorbing net 63, and can react with the purified liquid in the liquid absorbing net 63 again.

[0051] By adopting the above technical solution, harmful gases in the exhaust gas can be further purified, the purification effect of the exhaust gas can be improved, and the purification liquid can also be effectively saved.

[0052] As a preferred embodiment, the purification liquid includes a first purification liquid 12 and a second purification liquid 621, the first purification liquid 12 is poured into the first treatment chamber 1, and the second purification liquid 621 is poured into the liquid storage chamber 62, the product of the reaction between the first purification liquid 12 and the exhaust gas is insoluble in the solvent of the first purification liquid 12, and the product of the reaction between the second purification liquid 621 and the exhaust gas is a gas or a liquid or a solid soluble in the solvent of the second purification liquid 621;

[0053] By adopting the above technical scheme, the first purification liquid 12 in the first treatment chamber 1 can intercept the solid substances in the waste gas that are insoluble in the solvent of the first purification liquid 12, such as dust, and the insoluble substances generated after the reaction with the first purification liquid 12, and can intercept all the solid substances generated in the waste gas, so that they will not enter the second treatment chamber 61, and the bubble breaking net 22 will not be blocked in the first treatment chamber 1, and the product of the reaction between the second purification liquid 621 and the waste gas is gas or liquid or solid dissolved in the solvent of the second purification liquid 621, so the liquid absorption net 63 will not be blocked, and the remaining gas will be discharged from the exhaust port 42. Moreover, since the first purification liquid 12 will only intercept the solid substances in the waste gas that are insoluble in the solvent of the first purification liquid 12 and the products of the reaction with the waste gas that are insoluble in the solvent of the first purification liquid 12, therefore, after filtering the waste residue, the first purification liquid 12 can still continue to be recovered and used, so that the use of purification liquid can be saved and secondary pollution can be avoided or reduced.

[0054] As a preferred manner, the outlet pressure of the relief valve 64 decreases from top to bottom. Specifically, the difference between the liquid pressure at the corresponding position in the liquid storage chamber 62 and the preset pressure of the relief valve 64 decreases from top to bottom.

[0055] By adopting the above technical solution, since the outlet pressure of each overflow valve 64 decreases successively, the purified liquid in the liquid suction net 63 from top to bottom also gradually decreases, and the exhaust gas will also gradually decrease when passing through the liquid suction net 63 from top to bottom, thereby further saving the use of purified liquid.

[0056] As a preferred embodiment, the second treatment chamber 61 is cylindrical, the liquid storage chamber 62 is arranged around the second treatment chamber 61, the communication holes are divided into multiple groups, each group of communication holes is evenly arranged along the circumference of the second treatment chamber 61, each group of communication holes corresponds to a liquid absorbing net 63, the liquid absorbing end is evenly arranged along the circumference of the corresponding liquid absorbing net 63, and the liquid absorbing net 63 is connected to the corresponding communication hole at one end close to the second treatment chamber 61 through the liquid absorbing end;

[0057] By adopting the above technical solution, the liquid absorbing net 63 can evenly absorb the purified liquid in the liquid storage chamber 62 through the liquid absorbing end, thereby improving the purification efficiency.

[0058] As a preferred embodiment, it further comprises a liquid pump 71 and a gas flow sensor 72, wherein the output end of the liquid pump 71 is connected to the liquid storage chamber 62, and the gas flow sensor 72 is disposed in the gas outlet 41, and the liquid pump 71 and the gas flow sensor 72 are also connected to the controller signal;

[0059] By adopting the above technical solution, the input end of the liquid pump 71 is used to absorb the second purified liquid 621, so that the second purified liquid 621 is replenished in the liquid storage chamber 62 through the output end. At the same time, the gas flow sensor 72 can detect the flow rate of the exhaust gas through the outlet 41 and send a signal to the controller. The controller controls the output of the liquid pump 71 according to the size of the exhaust gas flow rate, and then controls the pressure of the liquid in the liquid storage chamber 62, changes the difference between the pressure of the liquid in the liquid storage chamber 62 and the preset pressure of the overflow valve 64, ensures the effective purification of the exhaust gas, and saves the use of purification liquid.

[0062] By adopting the above technical solution, when the exhaust gas enters the first treatment chamber 1 through the air duct 3, it can blow the propeller 82 in the air duct 3 to rotate, thereby driving the transmission rod 81 to rotate, and driving the ring gear 91 and the bubble breaking net 22 to rotate, thereby saving power energy.
