[0002] Wet desulfurization is one of the most common desulfurization methods. It uses liquid absorbents such as limestone slurry, ammonia water, etc. to react with SO2 in the flue gas to form sulfates, and then separates them from the flue gas by precipitation or crystallization. In a wet desulfurization tower, the gas-lifting hood is a key component, which is used to guide the flue gas to rise and pass through the tower body, while preventing the backflow and splashing of the absorbent liquid, ensuring sufficient contact between the flue gas and the absorbent, and improving the desulfurization efficiency.

[0003] The installation of the gas-lifting hood in the prior art needs to be fixed by multiple bolts, resulting in a large amount of time spent during its installation. Summary of the Utility Model

[0036] Embodiment 1

[0037] Referring to Figures 1 - 7 , for the first embodiment of the present utility model, a gas-lifting hood is provided. This device includes an installation unit 100 and an exhaust unit 200;

[0038] The exhaust unit 200 includes a gas-lifting shell 201 disposed on the installation unit 100 and detachably connected to the installation unit 100, and a plurality of diversion components 202 disposed obliquely on the gas-lifting shell 201. There are at least four and at most no more than ten diversion components 202. The installation unit 100 includes a base 101 disposed on the gas-lifting shell 201, a plurality of support pads 102 disposed on the base 101 and snap-connected to the gas-lifting shell 201. To maintain stability, the number of support pads 102 is at least four and symmetrically distributed, and at most no more than ten, and a snap connection mechanism 103 disposed on the support pads 102 and snap-connected to the gas-lifting shell 201.

[0039] Among them, a lining plate 105 is embedded in the base 101 and inside the gas-lifting shell 201. Through the lining plate 105, it is possible to prevent the falling water from entering the gas-lifting shell 201.

[0040] During use, the installation unit 100 is installed at the air outlet of the vulcanization equipment and sealed. Then, the air-lifting shell 201 is placed on the base 101. There is an installation gap between the air-lifting shell 201 and the base 101 through the support pad 102, which can prevent water from entering the base 101 through the gap. Then, the air-lifting shell 201 is fixed by the clamping mechanism 103, and the installation of the air-lifting shell 201 is completed.

[0041] During use, the liquid is sprayed from above, and the gas enters the air-lifting shell 201 and then sprays out from the gap between the air-lifting shell 201 and the diversion component 202, so that the gas and the liquid come into contact and react and decompose in the air. The water flow falls on the diversion component 202, and the diversion component 202 diverts the water to prevent water from entering the air-lifting shell 201, and the multiple diversion components 202 enable the gas to escape evenly and dispersedly.

[0042] Embodiment 2

[0043] Refer to Figures 1 - 7 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the diversion component 202 includes a water baffle 202a inclinedly arranged on the air-lifting shell 201, water baffle side plates 202b and an air outlet baffle 202c respectively arranged on both sides of the water baffle 202a.

[0044] Among them, water collecting plates 202d are inclinedly arranged on both the water baffle side plates 202b and the air outlet baffle 202c. The water collecting plates 202d can collect water and prevent water from splashing into the air-lifting shell 201.

[0045] Furthermore, a water guide plate 203 is inclinedly arranged on the air-lifting shell 201; the water guide plate 203 is located below the water baffle 202a, and the water guide plate 203 can collect the water falling from the water baffle 202a, so that the water can be conveniently collected and processed.

[0046] During use, the sprayed liquid falls on the water baffle 202a. The water baffle side plates 202b prevent water from flowing down the side of the water baffle 202a, and the air outlet baffle 202c prevents water from flowing into the air-lifting shell 201. The flue gas then sprays out through the gap between the diversion component 202 and the air-lifting shell 201, can come into contact and react with the liquid, and the sprayed liquid will not flow into the air-lifting shell 201.

[0047] The remaining structure is the same as that of Embodiment 1.

[0048] Embodiment 3

[0049] Refer to Figures 1 - 7, which is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that the clamping mechanism 103 includes a sliding column 103a slidably disposed on the support pad 102, a plurality of connecting sleeves 103b all disposed on the sliding column 103a, a plurality of limiting blocks 103d all disposed on the air-lifting shell 201, and a limiting rod 103c disposed on the connecting sleeve 103b and clamped with the limiting block 103d. The number of the connecting sleeves 103b and the limiting blocks 103d is the same, at least three and at most five.

[0050] Further, a limiting mechanism 104 for clamping with the sliding column 103a is disposed on the base 101. The sliding column 103a is limited by the limiting mechanism 104 to prevent the sliding column 103a from moving during use.

[0051] Wherein, the limiting mechanism 104 includes a handle 104a disposed on the sliding column 103a, an elastic member 104c disposed on the base 101, and a limiting sleeve 104b disposed on the elastic member 104c and abutted against the handle 104a. A plugging groove for embedding the end of the limiting rod 103c is disposed on the support pad 102.

[0052] During the use process, the air-lifting shell 201 is erected on the base 101. By pulling the sliding column 103a, the sliding column 103a drives the connecting sleeve 103b to move, and the connecting sleeve 103b drives the limiting rod 103c to move, so that the limiting rod 103c is inserted into the limiting block 103d and located in the plugging groove, thereby being able to limit the air-lifting shell 201 to prevent the air-lifting shell 201 from moving. After the installation is completed, at this time, the handle 104a is located at the limiting sleeve 104b, and the elastic member 104c pushes the limiting sleeve 104b to move upward, so that the limiting sleeve 104b abuts against the handle 104a to limit the handle 104a and prevent the handle 104a from moving.

[0053] The remaining structures are the same as those in Embodiment 2.

[0054] Embodiment 4

[0055] Refer to Figures 1 - 7 , which is the fourth embodiment of the present utility model. This embodiment provides a desulfurization reaction tower, which is characterized in that it includes the above-mentioned air-lifting hood, and further includes a reaction tower unit 300, including a tower body 301 having a drain port 301a, and two symmetrically disposed and obliquely disposed drain plates 302 in the tower body 301; the lower end of the drain plate 302 is located at the drain port 301a, and the inclination angle of the drain plate 302 ≥ 15°; the base 101 is disposed on the drain plate 302.

[0056] During use, when water flows down from the diversion component 202, it flows into the drainage plate 302 through the air-lifting shell 201. The drainage plate 302 is inclined, and two drainage plates 302 are inclined, so that the middle position of the drainage plate 302 is relatively low. After the water flows onto the drainage plate 302, it can converge and then be discharged through the drainage port 3019, thus facilitating drainage. An inclination angle ≥ 15° can avoid water accumulation and better discharge the water, and can discharge the water from the tower body 301.

[0057] The remaining structures are the same as those in Embodiment 3.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
