Description

Technical Field

[0001] This utility model relates to the field of atmospheric desulfurization technology, specifically to an atmospheric desulfurization device. Background Technology

[0002] Gas desulfurization methods can be divided into two main categories: dry desulfurization and wet desulfurization. Dry desulfurization uses solid adsorbents to remove hydrogen sulfide. Commonly used adsorbents include zinc oxide, activated carbon, and molecular sieves. Wet desulfurization uses liquid absorbents to wash the gas to remove hydrogen sulfide. The most commonly used method is the amine desulfurization process.

[0003] A patent for an atmospheric desulfurization device for environmental engineering, with announcement number CN211537190U, includes a main body of the device. A blower and a liquid pump are installed on both sides of the main body. The output end of the blower is connected to a duct, the end of which passes through the bottom of the main body and is connected to an air outlet. The output end of the liquid pump passes through the bottom of the main body via a liquid delivery pipe and is connected to a spray head. A heat exchange box is fixed on one side of the main body. In this atmospheric desulfurization device for environmental engineering, when desulfurizing the atmosphere, workers introduce air into the desulfurization chamber, then connect the liquid pump to the desulfurization liquid tank, turn on the liquid pump to draw out the desulfurization liquid and atomize it through the spray head, and then turn on the blower to blow air out through the air outlet. As the atomized desulfurization liquid falls downwards, it can be blown upwards. Simultaneously, in conjunction with the atomizing spray head, this improves the thorough mixing of the atomized desulfurization liquid with the atmosphere, enhancing the reaction effect.

[0004] However, because the process of blowing air into the desulfurization tank using a blower accelerates the emission of gas from the desulfurization tank, it may not be able to increase the residence time of the atmosphere in the desulfurization tank when desulfurizing the atmosphere. This may result in some gases with short reaction times or those that have not been desulfurized being discharged from the desulfurization chamber, thus reducing the desulfurization effect on the atmosphere.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide an atmospheric desulfurization device that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted:

[0008] An atmospheric desulfurization device includes: a treatment tank, an exhaust pipe fixedly installed on the treatment tank, a suction fan for conveying air to be desulfurized into the treatment tank, a first desulfurization component disposed inside the treatment tank, a baffle fixedly installed on the treatment tank, a through opening opened on the baffle, and a second desulfurization component disposed between the baffle and the treatment tank.

[0009] The first desulfurization component includes: a lower partition plate fixedly installed inside the treatment tank, an upper partition plate fixedly installed inside the treatment tank, an isolation mesh fixedly installed on the lower partition plate and the upper partition plate respectively, and desulfurization filler filling between the two isolation meshes.

[0010] Furthermore, the lower partition and the upper partition are arranged in an alternating vertical arrangement.

[0011] Furthermore, the top of the baffle is fixedly connected to the top wall of the processing tank, and the bottom of the baffle is fixedly installed on one side of the top of the upper partition.

[0012] Furthermore, the second desulfurization component includes: two first guide plates fixedly installed on the baffle to guide air flow, a second guide plate fixedly installed inside the treatment tank, a spray pipe fixedly installed on the treatment tank to transport desulfurization liquid, a plurality of atomizing nozzles fixedly installed at equal intervals on the spray pipe, and a drain pipe fixedly installed on the treatment tank.

[0013] Furthermore, the first guide plate is obliquely and fixedly installed on the surface of one side of the baffle.

[0014] Furthermore, the second guide vane is staggered with the two first guide vanes.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the process of air desulfurization, since the lower baffle and the upper baffle are staggered, the air to be treated enters the desulfurization packing and is processed, which increases the contact time between the air and the desulfurization packing. After completing one desulfurization process, the air flows through the S-shaped channel formed between the second guide plate and the two first guide plates, which allows the air to come into contact with the atomized desulfurization liquid multiple times, increasing the residence time of the atmosphere in the treatment tank, thereby improving the desulfurization effect and purifying harmful dust in the air.

[0023] like Figures 1 to 3 As shown, this utility model discloses an atmospheric desulfurization device, comprising: a treatment tank 1, an exhaust pipe 101 fixedly installed on the treatment tank 1, a suction fan 2 for conveying air to be desulfurized into the treatment tank 1, the outlet end of the suction fan 2 being fixedly connected to the bottom of the treatment tank 1, the air to be desulfurized being conveyed to the interior of the treatment tank 1 through the outlet end of the suction fan 2 for desulfurization treatment, a first desulfurization component 3 disposed inside the treatment tank 1, a baffle 4 fixedly installed on the treatment tank 1, the top of the baffle 4 being fixedly connected to the top wall of the treatment tank 1, the bottom of the baffle 4 being fixedly installed on one side of the top of the upper partition 302, the baffle 4 separating dry desulfurization and wet desulfurization so that they do not affect each other, an opening 401 opened on the baffle 4, and a second desulfurization component 5 disposed between the baffle 4 and the treatment tank 1;

[0024] The first desulfurization component 3 includes: a lower partition 301 fixedly installed inside the treatment tank 1, an upper partition 302 fixedly installed inside the treatment tank 1, the lower partition 301 and the upper partition 302 being staggered vertically, the air to be treated entering the desulfurization packing 304 through the opening between the lower partition 301 and the treatment tank 1, the desulfurization packing 304 adsorbs and removes sulfur from the air, and then flows out through the opening between the upper partition 302 and the treatment tank 1, thereby increasing the contact time between the air and the desulfurization packing 304 and improving the desulfurization effect, and an isolation net 303 fixedly installed on the lower partition 301 and the upper partition 302 respectively, and a desulfurization packing 304 filled between the two isolation nets 303.

[0025] In air desulfurization, the air to be treated is first introduced into the treatment tank 1 by the suction fan 2. The air to be treated enters the desulfurization packing 304 through the opening between the lower baffle 301 and the treatment tank 1. The desulfurization packing 304 adsorbs and removes sulfur from the air, and then flows out through the opening between the upper baffle 302 and the treatment tank 1, completing one desulfurization process.

[0026] The second desulfurization component 5 includes: two first guide plates 501 fixedly installed on the baffle 4 to guide the air flow; the first guide plates 501 are inclinedly fixedly installed on one side of the surface of the baffle 4 to facilitate the flow of desulfurization liquid sprayed by the atomizing nozzles 504 to the bottom of the treatment tank 1 and to the outside through the drain pipe 505; a second guide plate 502 fixedly installed inside the treatment tank 1; the second guide plate 502 and the two first guide plates 501 are staggered to form an S-shaped channel between the second guide plate 502 and the two first guide plates 501, which promotes multiple contact between the air and the atomized desulfurization liquid during spraying; a spray pipe 503 fixedly installed on the treatment tank 1 to transport the desulfurization liquid; several atomizing nozzles 504 fixedly installed at equal intervals on the spray pipe 503; and a drain pipe 505 fixedly installed on the treatment tank 1, with one end of the drain pipe 505 connected to a conveying pipe to discharge the treated desulfurization liquid.

[0027] After completing one desulfurization treatment, air enters the space where the spray pipe 503 is located through the inlet 401. The top of the spray pipe 503 is connected to an external conveying pipe, which causes the conveyed desulfurization liquid to be sprayed out from several atomizing nozzles 504 at the lower end of the spray pipe 503. This creates a mist wall between the first guide plate 501 and the second guide plate 502, allowing the conveyed air to flow through an S-shaped channel between the second guide plate 502 and the two first guide plates 501. This allows the air to come into contact with the atomized desulfurization liquid multiple times, increasing the residence time of the atmosphere in the treatment tank 1, thereby improving the desulfurization effect and purifying harmful dust in the air.

[0028] Working principle: When the power is turned on and the atmospheric desulfurization equipment is in use, the suction fan 2 first introduces the air to be treated into the treatment tank 1. The air to be treated enters the desulfurization packing 304 through the opening between the lower baffle 301 and the treatment tank 1. The desulfurization packing 304 adsorbs and removes sulfur from the air, and then flows out through the opening between the upper baffle 302 and the treatment tank 1, completing one desulfurization treatment. After that, the air enters the space where the spray pipe 503 is located through the inlet 401, and is then connected to the top of the spray pipe 503 by an external delivery pipe. The desulfurization liquid is sprayed from several atomizing nozzles 504 at the lower end of the spray pipe 503, forming a mist wall between the first guide plate 501 and the second guide plate 502. The air is then transported through an S-shaped channel between the second guide plate 502 and the two first guide plates 501, allowing the air to come into contact with the atomized desulfurization liquid multiple times, thereby improving the desulfurization effect and purifying harmful dust in the air. The purified air is discharged to the outside through the exhaust pipe 101, and the treated desulfurization liquid is discharged through the drain pipe 505.
