Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of desulfurization equipment, and particularly relates to a desulfurization device for industrial waste gas. BACKGROUND

[0002] Desulfurization refers to the removal of sulfur from fuel before combustion and the removal of sulfur before flue gas emission. It is one of the important technical measures to prevent and control air pollution. Desulfurization methods generally include pre-combustion, in-combustion and post-combustion desulfurization. With the development of industry and the improvement of people's living standards, the demand for energy is increasing, and SO2 in coal-fired flue gas has become the main cause of air pollution. Reducing SO2 pollution has become an urgent task in the current air environmental management. Many flue gas desulfurization processes have been widely used in industry, and they also have important practical significance in the treatment of industrial waste gas such as the tail gas of various boilers and incinerators. When treating industrial waste gas, a desulfurization tower is usually used for desulfurization, and the desulfurization tower generally includes a tower body, a spraying layer, a demister and a circulating system. The demister in the desulfurization tower is located at the top of the desulfurization tower, and removes water vapor carrying sulfuric acid salt crystals in the gas after desulfurization through interception and inertial collision, so the demister needs to be flushed regularly to ensure normal use.

[0003] A desulfurization tower demisting device is disclosed in Chinese patent application file CN119158342A. The desulfurization tower demisting device includes a desulfurization tower, and a demisting device is installed at the lower end of the desulfurization tower smoke outlet. The demisting device includes a circular mist collector and a plurality of spraying devices. The outer part of the circular mist collector is coaxially fixed with a ring-shaped guide rail. The plurality of spraying devices are evenly distributed in a circular array, and each spraying device is slidably installed on the ring-shaped guide rail through a lower end sliding block. Each of the plurality of spraying devices has a nozzle at one end close to each other. When the circular mist collector needs to be cleaned, the plurality of spraying devices can synchronously move along the ring-shaped guide rail to make a circular motion around the axis of the circular mist collector. The cleaning liquid is uniformly sprayed on the circular mist collector through the plurality of spraying devices.

[0004] However, the structure design of the above-mentioned related technology can make a circular motion for cleaning when cleaning the demister in the desulfurization tower. However, the blades in the demister are usually in a wave shape. When the water flow flushes the demister, only the middle part of the wave-shaped blades can be cleaned by the water flow, so that the flushing force on the middle part of the blades is small. The demister cannot be flushed for a long time, so that the middle part of the blades is prone to scaling, which reduces the flue gas passage and affects the flue gas discharge efficiency. Subsequent cleaning is required.

The movable plate two 224 is located at the bottom end of the mounting seat 211, and the movable plate one 223 is hinged with the hinged seat 222 on the bottom of the fixed plate 221 through a pin shaft. A torque spring (not shown in the figure) is arranged between the outermost movable plate one 223 and the hinged seat 222 connected thereto, and between the outermost movable plate two 224 and the hinged seat 222 connected thereto, so that the outermost movable plate one 223 and the outermost movable plate two 224 can be automatically reset. In the initial state, the movable plate one 223 and the movable plate two 224 are both arranged obliquely to intercept the mist particles and slurry droplets entrained in the flue gas.

The adjusting plate 34 is in a plurality of numbers, and the plurality of adjusting plates 34 are installed at the bottom of the sliding bar 33 along the length direction of the sliding bar 33. The bottom of the adjusting plate 34 penetrates through the bottom of the mounting frame 31 and extends to the outside of the mounting frame 31, and the bottom of the mounting frame 31 is provided with a groove for the sliding of the adjusting plate 34.

[0052] When the defogging mechanism 20 needs to be cleaned, the water supply frame 14 sprays water flow to the movable plate one 223 and the movable plate two 224 through the spray head 15, so as to flush the fog particles and slurry drops on the movable plate one 223 and the movable plate two 224. During the flushing process, the upper hydraulic cylinder 32 is first started, and at this time, the upper hydraulic cylinder 32 drives the upper sliding bar 33 to slide in the mounting frame 31. During the sliding process of the upper sliding bar 33, the upper adjusting plate 34 pushes the movable plate one 223 to rotate on the hinge seat 222, so as to adjust the inclination direction of the movable plate one 223, and enable the upper spray head 15 to comprehensively flush the movable plate one 223. When the movable plate one 223 is flushed, the upper hydraulic cylinder 32 drives the adjusting plate 34 on the sliding bar 33 to reset, so as to drive the movable plate one 223 to reset.

When the movable plate two 224 is flushed, the lower hydraulic cylinder 32 drives the adjusting plate 34 on the sliding bar 33 to reset, so as to drive the movable plate two 224 to reset.

[0054] As shown in Figure 2 , Figure 4 and Figure 7 , the scraping mechanism 40 includes a lifting mechanism and a plurality of cleaning assemblies 42. The lifting mechanism is arranged at the top end of the mounting seat 211, and the plurality of cleaning assemblies 42 are arranged on the lifting mechanism. The plurality of cleaning assemblies 42 are arranged outside the plurality of fixed plates 221, so as to isolate the fixed plates 221 and prevent the fog particles and slurry drops from adhering to the fixed plates 221.

[0055] The lifting mechanism can drive the cleaning assemblies 42 to move up and down, so that the cleaning assemblies 42 move to the outside of the movable plate one 223 or the movable plate two 224, thereby enabling the cleaning assemblies 42 to be directly flushed by the water flow of the spray head 15, so as to comprehensively clean the defogging mechanism 20. During the movement of the cleaning assemblies 42 to the movable plate one 223 or the movable plate two 224, the soft dirt condensed on the movable plate one 223 or the movable plate two 224 can be scraped, thereby improving the cleaning effect of the defogging mechanism 20 and prolonging the service life of the defogging mechanism 20.

[0062] The upper adjusting plate 34 pushes the movable plate 223 to rotate on the hinge seat 222 during the moving process, so that the spray head 15 can fully wash the movable plate 223.

[0063] When the movable plate 223 rotates to the vertical state during the resetting process, the motor 44 drives the mounting ring 41 to move upward through the lead screw 43, the mounting ring 41 drives the scraper 421 to move upward through the connecting plate 422 during the moving process, and the soft dirt on the movable plate 223 is scraped off, at this time, the scraper 421 can be washed by the spray head 15 to prevent the scraper 421 from adhering to the fog particles and slurry drops, and when the scraper 421 cleans the movable plate 223, the motor 44 drives the scraper 421 to reset through the mounting ring 41 on the lead screw 43.
