Description

Technical Field

[0001] The invention relates to the technical field of steam removal of ammonia nitrogen, and in particular to a gas washing device. Background Art

[0002] Steam in different evaporation systems generally has the opportunity to come into contact with ammonia nitrogen, so that the steam in the system contains ammonia nitrogen and is contaminated, which requires the removal of ammonia nitrogen from the steam before use. Traditional ammonia nitrogen removal technology generally uses acid for absorption, but the current treatment efficiency of such equipment is low, and the absorption is not thorough, resulting in the outlet steam still containing a small amount of ammonia nitrogen; and the current absorption equipment needs to be made of metal materials due to mechanical performance requirements, and there are many pipe openings on the equipment, which easily causes gas and acid leakage and pollutes the environment. Summary of the invention

[0003] Based on this, it is necessary for the present invention to provide a low-cost gas washing device that can thoroughly absorb ammonia nitrogen in steam, improve treatment efficiency, prevent leakage, and has low cost.

[0004] In order to achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0005] A scrubbing device, comprising:

[0006] a first tower body, wherein a first filler portion is installed in the first tower body, a first opening is provided on the top of the first tower body, a first steam pipe is elastically connected to the first tower body corresponding to the first opening, and a steam inlet is provided in the first steam pipe;

[0007] a second tower body, wherein at least a second filler portion is installed in the second tower body, a second opening is provided on the top of the second tower body, a second steam pipe is elastically connected to the second tower body corresponding to the second opening, and the second steam pipe is provided with a steam outlet;

[0010] The above-mentioned scrubbing device adopts two connected tower bodies for scrubbing. After the first elution in the first packing part, the second elution is performed in the second packing part. Moreover, the first packing part can fill the tower body, the height is high enough, the elution stroke is long, and the secondary elution can more thoroughly wash away the ammonia nitrogen in the steam, thereby improving the processing efficiency of the equipment. Steam pipes are arranged on the tops of the two tower bodies, and the steam pipes are elastically connected to the tower bodies, which can buffer vibrations and prevent leakage. The tower bodies themselves are not provided with pipe openings, so that there will be no leakage in the tower bodies themselves, thereby preventing leakage of the equipment. The equipment can be made of plastics such as pph instead of metal, which can reduce the cost of the equipment.

[0011] In some embodiments, the first steam pipe is connected to the first tower body via a first elastic joint, and the second steam pipe is connected to the second tower body via a second elastic joint.

[0012] In some embodiments, a third filling part is further installed in the second tower body, and the second filling part and the third filling part are installed with spacing from the bottom to the top of the second tower body.

[0013] In some embodiments, a first spray pipe opening is opened at the top of the first steam pipe, a first spray pipe is provided at the first spray pipe opening, and the acid liquid tank is connected to the first spray pipe through the first pipeline; a second spray pipe opening is opened at the top of the second steam pipe, a second spray pipe is provided at the second spray pipe opening, and the acid liquid tank is connected to the second spray pipe through the second pipeline.

[0015] In some embodiments, the height of the first filling portion is greater than the height of the second filling portion and the height of the third filling portion.

[0016] In some embodiments, the third packing part is a ceramic ball ring.

[0017] In some embodiments, one end of the connecting tube is connected to the first tower body via a third elastic joint, and the other end of the connecting tube is connected to the second tower body via a fourth elastic joint.

[0018] In some embodiments, the connecting pipe is U-shaped.

[0021] In order to facilitate understanding of the present invention, the present invention will be described more fully below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0023] Example

[0024] Please refer to Figure 1 The present invention provides a scrubbing device 100, comprising a first tower body 10, a second tower body 20, a connecting pipe 30 and an acid liquid tank 40. A first packing portion 11 is installed in the first tower body 10, a first opening 12 is provided at the top of the first tower body 10, a first steam pipe 13 is elastically connected to the first tower body 10 corresponding to the first opening 12, and a steam inlet 14 is provided in the first steam pipe 13; at least a second packing portion 21 is installed in the second tower body 20, a second opening 22 is provided at the top of the second tower body 21, a second steam pipe 23 is elastically connected to the second tower body 20 corresponding to the second opening 22, and a steam outlet 24 is provided in the second steam pipe 23; the connecting pipe 30 is elastically connected to the bottom of the first tower body 10 and the bottom of the second tower body 20 respectively; the acid liquid tank 40 is connected to the connecting pipe 30, the acid liquid tank 40 is connected to the first steam pipe 13 through the first pipeline 41, and is connected to the second steam pipe 23 through the second pipeline 42.

[0025] During operation, steam enters the first tower body 10 from the steam inlet 14, and at the same time, the acid liquid in the acid liquid tank 40 is pumped to the first steam pipe 13 through the first pipeline 41, and then enters the first tower body 10, the steam contacts the acid liquid in the first packing part 11, and after the acid liquid absorbs the ammonia nitrogen in the steam, the steam enters the second tower body 20 through the connecting pipe 30, and the steam contacts the acid liquid in the second tower body 20 in the second packing part 21, and the acid liquid absorbs the ammonia nitrogen in the steam, thereby performing secondary deammoniation and nitrogen removal on the steam, and completely removing the ammonia nitrogen in the steam.

[0026] The first filler part 11 can fill the tower body, the height is high enough, the elution stroke is long, and the secondary elution can be added to more thoroughly wash out the ammonia nitrogen in the steam, thereby improving the processing efficiency of the equipment. The elastic connection between the steam pipe and the tower body can buffer vibration and prevent leakage, and the tower body itself is not provided with a nozzle, so the tower body itself will not leak, thereby better preventing equipment leakage. Since the tower body is not provided with a nozzle, its mechanical properties can be guaranteed, so it can be made of plastic material to reduce equipment cost.

[0027] In one embodiment, since the tower body is not provided with a nozzle, the first tower body 10, the second tower body 20, the first steam pipe 13 and the second steam pipe 23 are all made of PPH (high performance polypropylene) material. This can reduce the cost of the equipment and prevent leakage. Of course, the equipment can also be made of other plastic materials, preferably PPH.

[0028] In one embodiment, the first steam pipe 13 is elastically connected to the first opening 12 in the following manner: the first steam pipe 13 is connected to the first tower body 10 via a first elastic joint 15, and the second steam pipe 23 is connected to the second tower body 20 via a second elastic joint 25. The first elastic joint 15 and the second elastic joint 25 may be joints formed of rubber, for example.

[0029] In one embodiment, the first steam pipe 13 is provided with a first spray pipe opening 16, the first spray pipe opening 16 is provided with a first spray pipe 17, the acid tank 40 is connected to the first spray pipe 16 through a first pipeline 41; the second steam pipe 23 is provided with a second spray pipe opening 26, the second spray pipe opening 26 is provided with a second spray pipe 27, the acid tank 40 is connected to the second spray pipe 27 through a second pipeline 42. In this way, the acid in the acid tank 40 can enter the first tower body 10 and the second tower body 20 through the top of the first steam pipe 13 and the second steam pipe 23, and then spray into the first tower body 10 through the nozzle on the first spray pipe 16, and spray into the second tower body 20 through the nozzle on the second spray pipe 27. In this way, the acid enters the steam pipe from the top and then enters the tower body, the spraying pressure is greater, and the spraying effect is better.

[0030] Please refer again Figure 1 In one embodiment, the second packing part 21 and the third packing part 28 are installed in the second tower body 20 in order from the bottom to the top. The first packing part 11 and the second packing part 21 are used to contact the acid solution and the steam, so as to remove the ammonia nitrogen in the steam, and the third packing part 28 can remove the water droplets brought up by the steam flow, so as to make the steam cleaner.

[0031] In one embodiment, the height of the first packing part 11 is greater than the height of the second packing part 21 and the height of the third packing part 28. Therefore, the first packing part 11 can fully contact the acid solution and the steam.

[0032] In one embodiment, the third filler part 28 is a ceramic ball ring. The friction between the ceramic ball ring and the plastic material is greater than that between the metal material and the ceramic ball ring, so that the ceramic ball ring and the plastic material equipment can be used better together. Since the cost of the ceramic ball ring is lower than that of the PTFE filler, the cost of the entire equipment can be reduced.

[0033] In one embodiment, the second spray pipe 27 passes through the third packing part 28, so that the spray head of the second spray pipe 27 is located between the second packing part 21 and the third packing part 28. In this way, the sprayed acid enters the second packing part 21 instead of the third packing part 28, thus avoiding the acid entering the third packing part 28 and causing waste, and also preventing the acid from contaminating the third packing part 28.

[0034] In one embodiment, the connecting pipe 30 is made of plastic material, for example, made of PPH material consistent with the tower body. The connecting pipe 30 is U-shaped. Of course, in other embodiments, the connecting pipe 30 can also be a straight pipe.

[0035] In one embodiment, one end of the connecting pipe 30 is connected to the first tower body 10 via a third elastic joint 31, and the other end of the connecting pipe 30 is connected to the second tower body 20 via a fourth elastic joint 32. In this way, the connection between the connecting pipe 30 and the tower body can also buffer vibration, ensuring a more stable connection between the connecting pipe 30 and the tower body.

[0036] In one embodiment, the first pipeline 41 and the second pipeline 42 can be combined into one, and then separated when the first spray pipe 17 and the second spray pipe 27 are respectively connected. A circulation pump 43 is provided on the first pipeline 41 and the second pipeline 42 to more efficiently pump the acid solution into the tower body.

[0037] In one embodiment, a drain pipe 44 is provided at the bottom of the acid liquid tank 40 to facilitate maintenance and cleaning of the acid liquid tank 40 and the connecting pipe 30 , the first tower body 10 and the second tower body 20 .

[0038] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
