Problems solved by technology

[0003] Most of the existing desulfurization towers use spraying to desulfurize the combustion exhaust gas, such as a desulfurization tower proposed by Chinese patent announcement number CN107739637A, a desulfurization tower proposed by Chinese patent announcement number CN107261809A, etc. Although spraying can increase the contact range between neutralizing liquid and exhaust gas, the efficiency is not high, and multi-stage spraying is required to ensure sufficient desulfurization effect, and spraying will also be affected by air flow, resulting in incomplete desulfurization the situation happened

Embodiment 1

[0019] see Figure 1-2 , a high-efficiency desulfurization tower, including a tower body 1, the tower body 1 is in the shape of a cuboid, and a discharge tower 2 and a transfer tower 3 are arranged in parallel and sequentially discharged in the tower body 1, between the discharge tower 2 and the transfer tower 3 A sealing plate is provided, and two input towers 4 arranged side by side in the vertical direction are arranged on the other side of the transfer tower 3, and the two input towers 4 are separated by a partition 5, and the bottom of each input tower 4 is provided with a There is a lime slurry tank 6 with an opening at the top of the lime slurry tank 6. The lime slurry tank 6 is used to load lime slurry, and firstly purify the gas that needs to be desulfurized. The side of the tower body 1 is provided with an input pipe 9, and the input pipe 9 has Two branch pipes, the branch pipes are inserted into the input tower 4 one by one, and a plurality of shunt insertion pipes ...

Embodiment 2

[0024] refer to image 3 On the basis of Embodiment 1, the front end of the transfer pipe 12 is in a closed state and extends into the air distribution pipe 16, and a plurality of internal pressurization connecting pipes 27 communicating with the transfer pipe 12 are arranged in the air distribution pipe 16, The diameter of described internal pressurization connecting pipe 27 is less than the width of protruding shower head 26, when carrying out the omnidirectional ejection of gas by gas distribution pipe 16, the speed when gas ejection can be improved through internal pressurization connecting pipe 27, thereby It has ensured that the protruding nozzle 26 positioned at the lower half of the gas distribution pipe 16 can carry out the gas ejection work smoothly, and the dispersion of the gas has been guaranteed, that is, the sufficient contact of the gas and the lye has been guaranteed.

Embodiment 3

[0026] On the basis of Example 1, a heat exchange tube is provided at the bottom of the lime slurry tank 6. When the lime slurry tank 6 is performing desulfurization work, the heat in the waste gas is transferred to the lime slurry, and by adding Cold water can both recover waste heat and avoid slurry splashing caused by excessive temperature in the lime slurry tank 6 .

Abstract

The invention discloses an efficient desulfurizing tower. The tower comprises a tower body, wherein the tower body is cuboid-shaped; a discharge tower and a transfer tower which are sequentially arranged in parallel are arranged in the tower body; a sealing plate is arranged between the discharge tower and the transfer tower; two input towers which are arranged in parallel in a vertical directionare arranged on the other side of the transfer tower; the two input towers are separated by a partition plate; a lime slurry pool is arranged at the bottom of each input tower, an opening is formed inthe top of each lime slurry pool, an input pipe is arranged on the side face of the tower body, the input pipe is provided with two branch pipes, the branch pipes are inserted into the input towers in a one-to-one correspondence mode, a plurality of diverting insertion pipes are arranged on the branch pipes, and the bottoms of the diverting insertion pipes are located in the lime slurry pools; and a transfer pipe is arranged in the transfer tower and is in butt joint with the input tower through a connecting inner pipe. When the efficient desulfurizing tower is used for desulfurizing gas, desulfurization efficiency is greatly improved through multi-stage absorption; and aeration absorption is carried out in an airflow dispersion mode through the arrangement of gas distribution pipes, so desulfurization effect is ensured.

Description

technical field [0001] The invention relates to environmental protection facilities, in particular to a high-efficiency desulfurization tower. Background technique [0002] The desulfurization tower is an equipment for desulfurization of industrial waste gas, and it is an important equipment in chemical equipment; my country is a country that uses large coal, and the combustion of combustibles will produce flue gas. Since flue gas usually contains a large amount of sulfide SO2 and dust, on the one hand it will It leads to highly corrosive acid rain. On the other hand, the dust discharged will bring air pollution and endanger human health. Not only the combustion of coal, but also the combustion of methane and coal gas will produce sulfide gas. [0003] Most of the existing desulfurization towers use the spray method to desulfurize the combustion exhaust gas, such as a desulfurization tower proposed by Chinese patent announcement number CN107739637A, a desulfurization tower pr...
