[0032] Embodiment:

[0033] As shown in Figure 1 、 2 The utility model provides a desulfurization spray device, including desulfurization tower main body 101, the passage that desulfurization tower main body 101 is provided with for smoke flow, the one end of desulfurization tower main body 101 is provided with the air inlet 103 communicated with it, and the one end away from air inlet 103 of desulfurization tower main body 101 is provided with the gas outlet 104 communicated with it. Desulfurization tower main body 101 bottom is provided with the liquid discharge port 105, and the valve is provided on the liquid discharge port 105. Desulfurization tower main body 101 upper and lower ends are provided with the spray pipe 106, and the opposite arrangement of two groups of spray pipe 106 is provided with multiple groups of spray head 107.

[0034] The device can supply smoke into desulfurization tower main body 101 through air inlet 103 when in use, supply desulfurizer to spray pipe 106, make desulfurizer spray out from multiple groups of spray head 107 to desulfurize smoke, and after desulfurization, smoke can be discharged through gas outlet 104, and waste liquid generated in the desulfurization process can be discharged through liquid discharge port 105.

[0035] As shown in Figure 2 、 3 , 5, in the embodiment, multiple groups of first baffle 202 and second baffle 205 are arranged at intervals in desulfurization tower main body 101, second baffle 205 is arranged at intervals between multiple groups of first baffle 202, and multiple groups of second baffle 205 and multiple groups of first baffle 202 form S-shaped flow channel for smoke flow. During the process of smoke supply, smoke flows along S-shaped flow channel, the more the number of first baffle 202 and second baffle 205, the longer the S-shaped flow channel formed, the longer the time that smoke stays in desulfurization tower main body 101, and the more sufficient the contact with desulfurizer. And the upper and lower ends of the inner side of desulfurization tower main body 101 are provided with multiple groups of receiving frame 108, and two groups of spray pipe 106 are respectively erected on multiple groups of receiving frame 108, first baffle 202 and second baffle 205 are clamped on receiving frame 108, receiving frame 108 supports spray pipe 106, and the gap between spray pipe 106 and desulfurization tower main body 101 is sealed, so that the end of first baffle 202 and second baffle 205 can be sealingly connected with desulfurization tower main body 101, avoiding that smoke directly flows out through the gap to reduce the spray desulfurization effect.

[0036] As shown in Figure 2As shown, in this embodiment, the bottom of the first partition 202 is detachably and sealed to the bottom surface of the desulfurization tower body 101 via a first connecting assembly. The first connecting assembly includes multiple sets of first snap-fit ​​brackets 201 disposed on the inner bottom of the desulfurization tower body 101, and the first partition 202 is snapped onto the multiple sets of first snap-fit ​​brackets 201. The installation of the first partition 202 is relatively simple; it only requires snapping the first partition 202 onto the first snap-fit ​​bracket 201, without the need for a complicated installation process.

[0037] like Figure 3 , 4 As shown, in this embodiment, the second partition 205 is detachably and sealed to the top of the desulfurization tower body 101 via a second connecting assembly. The second connecting assembly includes multiple sets of second snap-fit ​​brackets 203 spaced apart on the inner top of the desulfurization tower body 101. A through hole is provided on the second snap-fit ​​bracket 203, and a button 204 is slidably disposed in the through hole. The button 204 protrudes out of the second snap-fit ​​bracket 203.

An elastic element 207 is disposed between one end of the wedge block 206 and the inner side of the second partition 205. The end of the wedge block 206 is engaged in the through hole and abuts against the end of the button 204.

[0038] The second partition 205 can be moved upwards and engaged within the second retaining bracket 203. During its movement, the second partition 205 pushes the wedge block 206 to compress the elastic element 207 until the end of the wedge block 206 is engaged within the through hole, thus completing the installation of the second partition 205. Simply pressing the button 204 disengages the wedge block 206 from the through hole, making the installation and removal of the second partition 205 very convenient and quick, facilitating the adjustment of the S-shaped flow channel length. When the sulfur content of the flue gas is high, the length of the S-shaped flow channel is increased to improve the desulfurization effect; when the sulfur content of the flue gas is low, the length of the S-shaped flow channel is appropriately reduced to improve the desulfurization efficiency.

[0039] like Figure 1 , 2 As shown, in this embodiment, a hinged protective door 102 is provided on the side wall of the desulfurization tower body 101. The end of the protective door 102 is connected to the desulfurization tower body 101 by a latch. The protective door 102 can be opened to facilitate cleaning of the inside of the desulfurization tower body 101, and at the same time facilitate the loading and unloading of the first partition 202 and the second partition 205.
