Embodiment 1

[0018] A high-efficiency desulfurization tower includes a tower body 2, the upper and lower ends of the tower body 2 are respectively provided with an air outlet pipe 1 and an air inlet pipe 7, and a multi-layer spray device is arranged inside the tower body 2, and the spray device includes a spray Several spray branch pipes 4 of the main pipe 6 are characterized in that: a plurality of two-way nozzles 3 are arranged on the pipe wall above the spray main pipe 6, the spray angle of the two-way nozzles 3 is 90 degrees, and several nozzles 5 are arranged on the pipe wall below the spray branch pipe 4, located The heights set between the adjacent nozzles 5 on the same layer of spray branch pipes 4 are different, and the inner wall of the tower body 2 is provided with an outwardly convex annular tower ring 8 below each layer of the spray device, and the inner edge of the annular tower ring 8 is located On the spray path of the nozzle 5, a wire mesh defoaming device 9 is provided at ...

Embodiment 2

[0022] This embodiment is improved on the basis of Embodiment 1:

[0023] The inner diameter of the absorbent pipeline 6 decreases successively from the nozzle to the end, and the nozzle 5 adopts a spiral nozzle.

[0024] The advantages of the above improvements are: the absorbent pipeline adopts a variable diameter tube, which can make the pressure in the pipeline from the pipeline inlet to the end basically the same, and prevent the different spraying effects of different parts of the tower body caused by the different pipeline pressures, thereby affecting the desulfurization effect of the equipment; The spiral nozzle is adopted, which has the advantages of compact structure, not easy to be blocked, and capable of multi-angle and multi-layer spraying.

Embodiment 3

[0026] This embodiment is improved on the basis of the embodiment:

[0027] The air inlet pipe 7 is arranged obliquely downward on the tangential direction of the tower body 2, the axis of the air inlet pipe 7 is separated from the axis of the tower body 2, and the air outlet pipe 1 is vertically arranged on the top of the tower, and the diameter of the air outlet pipe 1 is smaller than that of the air inlet pipe 7 pipe diameters.

[0028] The advantages of the above improvements are: the air intake pipe is arranged obliquely downward and tangentially, which is beneficial to weaken the reflux vortex in the tower, reduce the pressure loss, prolong the contact time between the flue gas and the spray liquid, and prevent the spray liquid and mixed slurry from pouring back into the inlet. The gas pipe and the gas outlet pipe are vertically arranged on the top of the tower. Compared with the conventional horizontal installation on the outer wall of the tower, it can effectively prev...

Abstract

The invention discloses a high-efficiency desulfurization tower, which relates to the technical field of desulfurization equipment. The invention includes a tower body. A spray device with nozzles is arranged inside the tower body. A convex annular tower ring is also arranged on the inner wall of the tower body for spraying. The heights of the adjacent nozzles in the device are different. The present invention uses the height difference between the nozzles to realize that the water flow of different nozzles will not interfere with each other, and the ring tower can not only prevent the wall flow effect, but also buffer the jet water flow. function, prevent it from directly washing the inner wall of the tower, and protect the anti-corrosion layer on the inner wall of the tower. The invention has the advantages of simple structure and high desulfurization efficiency, and has broad application prospects in the field of desulfurization equipment.

Description

technical field [0001] The invention relates to the technical field of desulfurization devices, and more specifically relates to a high-efficiency desulfurization tower. Background technique [0002] At present, most industrial exhaust gases contain sulfur dioxide and other sulfides. If they are directly discharged into the air, they will have a serious impact on the environment. Therefore, the removal of sulfides in fuels is very important for environmental protection. There are three main ways to remove sulfides in fuel, which are before combustion, during combustion, and after combustion. The most commonly used method in the industry is to remove the sulfides produced by combustion in the exhaust gas after combustion. [0003] The most common way to remove sulfides in combustion tail gas is to spray the tail gas through a desulfurization spray tower. The detergent is usually a mixture of limestone and water, and the acid-base neutralization reaction is used to remove sulf...
