Description

TECHNICAL FIELD

[0001] The utility model mainly relates to desulfurization equipment technical field, concretely is a kind of energy-saving and environment-friendly desulfurization treatment device. BACKGROUND

[0002] With the acceleration of industrialization, large amounts of sulfur-containing flue gas generated by fossil fuel combustion has become one of the important sources of air pollution. These flue gases contain harmful substances such as sulfur dioxide, which not only causes serious damage to the environment, but also can harm human health.

[0003] Traditional desulfurization methods mostly use wet desulfurization technology, which sprays a solution containing alkaline components into sulfur-containing flue gas, causing the sulfur dioxide in the flue gas to react with the alkaline substances in the solution, thereby removing sulfides. However, traditional wet desulfurization systems have some shortcomings, such as low desulfurization efficiency, high energy consumption, and easy secondary pollution. In particular, when dealing with high-concentration or high-flow flue gas, the flue gas enters the desulfurization tower too quickly, which can easily lead to short contact time between the flue gas and the desulfurization slurry, and the desulfurization slurry accumulates at the bottom of the desulfurization tower. After mixing with the flue gas, the desulfurization slurry flows back to the bottom of the desulfurization tower, which can easily lead to uneven concentration of the desulfurization slurry at different depths, and uneven distribution of the desulfurization slurry can also reduce the desulfurization effect. SUMMARY

[0028] Embodiment: an energy-saving and environment-friendly desulfurization treatment device

[0029] As Figures 1-5 shown, an energy-saving and environment-friendly desulfurization treatment device, the specific structure includes:

[0030] Desulfurization tower 10, spray assembly 20, demister 30, homogenizing assembly 40, the middle part of one side of desulfurization tower 10 is fixedly installed with inlet pipe 101, the upper end of desulfurization tower 10 is fixedly installed exhaust pipe 102, one side of desulfurization tower 10 is fixedly installed with liquid inlet pipe 103 and liquid outlet pipe 104, the valve is arranged on liquid inlet pipe 103 and liquid outlet pipe 104, the inside of desulfurization tower 10 is equipped with spray assembly 20, spray assembly 20 is located above inlet pipe 101, the upper side of spray assembly 20 is fixedly installed with demister 30, the outer periphery of demister 30 is fixedly connected with the inner wall of desulfurization tower 10, homogenizing assembly 40 is arranged below the inside of desulfurization tower 10;

[0031] The spray assembly 20 comprises a spray pipe 201 fixedly installed inside the desulfurization tower 10, and the spray pipe 201 is located between the air inlet pipe 101 and the demister 30. The spray pipe 201 can be provided with multiple groups from top to bottom for use to improve the spraying effect. The bottom of the spray pipe 201 is fixedly installed with a plurality of uniformly distributed high-pressure atomizing nozzles 202. The liquid suction pipe 203 is installed outside the desulfurization tower 10, and the liquid suction pipe 203 is communicated with the water pump 204. The water pump 204 is electrically connected with the power supply. The lower end of the liquid suction pipe 203 penetrates through the bottom of the desulfurization tower 10 outside and is fixedly connected therewith. The upper end of the liquid suction pipe 203 extends into the desulfurization tower 10 and is fixedly connected with one side of the spray pipe 201. The liquid inlet pipe 203 and the spray pipe 201 are communicated with each other.

[0032] The working principle is as follows: when the flue gas desulfurization treatment is performed, the bottom of the inner wall of the desulfurization tower 10 is filled with desulfurization slurry through the liquid inlet pipe 103. The desulfurization slurry is a desulfurizer capable of reacting with sulfides. The power supply of the water pump 204 is turned on, so that the water pump 204 delivers the desulfurization slurry in the desulfurization tower 10 to the spray pipe 201 through the liquid suction pipe 203. The desulfurization slurry is sprayed in the form of fine droplets. The flue gas containing sulfur is introduced into the desulfurization tower 10 through the air inlet pipe 101. The flue gas moving upward in the desulfurization tower 10 can fully contact with the atomized desulfurization slurry, so as to absorb the sulfides in the flue gas by the desulfurization slurry. The flue gas after desulfurization treatment is dehumidified by the demister 30 and then discharged by the exhaust pipe 102. The homogenizing assembly 40 can stir the desulfurization slurry in the desulfurization tower to keep the desulfurization slurry in a good mixing state, thereby improving the uniformity and efficiency of the chemical reaction.

[0033] The homogenizing assembly 40 comprises a speed reducer 401 fixedly installed at the bottom of the desulfurization tower 10. The output shaft of the speed reducer 401 penetrates through the center of the bottom surface of the desulfurization tower 10 in a vertical direction and is rotatably connected with the bottom surface through a sealing bearing. One end of the speed reducer 401 located inside the desulfurization tower 10 is fixedly installed with a rotating shaft 402. The outer periphery of the rotating shaft 402 is fixedly installed with a plurality of uniformly distributed stirring blades 403.

[0034] When the homogenizing assembly 40 works, the speed reducer 401 is powered on to work. The output shaft of the speed reducer 401 drives the rotating shaft 402 connected therewith to drive the stirring blades 403 to rotate, so as to continuously stir the desulfurization slurry liquid at the bottom of the desulfurization tower 10 by the stirring blades 403, so that the desulfurization slurry keeps a good mixing state.

[0035] The upper end of the rotating shaft 402 is fixedly installed with an L-shaped supporting rod 50, the upper end of the L-shaped supporting rod 50 is fixedly installed with an arc-shaped baffle 60, the arc-shaped baffle 60 is in sliding fit with the inner wall of the desulfurization tower 10, and the arc-shaped baffle 60 can shield the opening of the gas inlet pipe 101.

[0036] The structure design can drive the arc-shaped baffle 60 to rotate in the desulfurization tower 10 through the L-shaped supporting rod 50 connected with the rotating shaft 402 when the rotating shaft 402 rotates, so that the arc-shaped baffle 60 can intermittently shield the opening of the gas inlet pipe 101, slow down the flue gas entering the desulfurization tower 10, and ensure that the flue gas entering the desulfurization tower 10 can be more fully contacted with the atomized desulfurization slurry, thereby improving the desulfurization effect of the device.

[0037] The outer side of the arc-shaped baffle 60 is provided with a plurality of uniformly distributed through grooves 601.

[0038] The gas inlet pipe 101 is arranged on the outer side of the desulfurization tower 10 in a left-high right-low inclined manner.
