Description

Technical Field

[0001] The present invention relates to the technical field of improving the efficiency and capacity of various flue gas desulfurization towers or spray-type flue gas cooling and dewhiting, and specifically to a high-efficiency conditioning reactor and a desulfurization tower. Background Art

[0002] In the field of air pollution control, gas-liquid reactors commonly used for mass transfer and heat transfer between gas and liquid include spray reactors, packed reactors, etc. Spray reactors have the advantages of high gas velocity, large flow rate, and low blockage probability, but have short reaction time and low efficiency; packed reactors have a large specific surface area of the packing layer, long gas-liquid contact time, and high reaction efficiency, but are prone to blockage and have high maintenance costs.

[0003] In the field of flue gas desulfurization, the currently most commonly used and stable desulfurization technology is the wet desulfurization technology. The preferred wet desulfurization process is, for example, the limestone-gypsum method. The structures of wet desulfurization towers mainly include: empty tower spray, Venturi tower, tray tower, etc. The desulfurization towers with the above structures have various unsatisfactory phenomena: for example, in the empty tower spray, its flue gas resistance is relatively low, but there are problems such as low desulfurization efficiency, high slurry-gas ratio, and poor desulfurization stability; for the tray tower, as the opening rate decreases, the desulfurization efficiency can increase accordingly, but at the same time, the flue gas resistance of the desulfurization tower also increases; and the slurry-gas ratios of current various types of desulfurization towers are relatively large, and the absorption components in the absorption liquid are much higher than the SO2 components absorbed in the flue gas. According to data analysis, the efficiency of the desulfurization slurry is about 20%, that is, the role of the desulfurization slurry in the whole desulfurization reaction has not been effectively exerted.

[0004] The reasons for this problem are as follows: 1. The mixing of desulfurization slurry and flue gas. In a common desulfurization tower (empty tower spray), the mixing of its slurry and flue gas mainly relies on the reverse convection of high-coverage slurry and flue gas. However, due to the structural reasons of the common desulfurization tower itself, the flue gas has a large deviation in flow in such towers, and it is impossible to make the flue gas uniform through the flue gas resistance formed by the slurry. This causes a deviation in the mixing of desulfurization slurry and flue gas in the tower, reducing the use efficiency and desulfurization efficiency of the desulfurization slurry; 2. The specific surface area of the desulfurization slurry reaction. The larger the specific surface area of the slurry reaction, the higher the desulfurization efficiency; according to the flue gas flow rate in the desulfurization tower and the structure of the desulfurization nozzle, most of the normal desulfurization slurry particles are in the range of 1.5 - 3.5 mm, and most of the reaction between the flue gas and the desulfurization slurry occurs on the surface of the particles within 100 - 200 um, accounting for about 25% of the volume of the slurry particles; 3. The uniformity of the flue gas. The higher the mixing uniformity of the flue gas and the desulfurization slurry, the higher the desulfurization efficiency; for general spray towers, there are varying degrees of flue gas deviation, and it is impossible to make the pollutant particles in the flue gas fully combine with the desulfurization slurry, resulting in penetration or over-flow in different regions of the tower diameter cross-section, reducing the efficiency and effective utilization rate of the entire desulfurization tower. Therefore, we propose a high-efficiency conditioning reactor and a desulfurization tower to solve the above problems. Summary of the Invention

Specific embodiments

Apparently, the described embodiments are some, but not all, of the embodiments of the present invention.

[0043] The embodiments of the present application provide an efficient conditioning reactor and a desulfurization tower, which solve the problems of low spray desulfurization efficiency, high slurry-liquid-to-gas ratio and poor desulfurization stability of the existing desulfurization tower.

[0044] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0045] The embodiments of the present invention disclose an efficient conditioning reactor and a desulfurization tower.

[0046] Embodiment 1:

[0047] The embodiments of the present invention disclose an efficient conditioning reactor and a desulfurization tower, according to the attached Figure 1 、 2, as shown in Figures 3 and 5, it includes a reaction efficiency unit 1, and the reaction efficiency unit 1 includes a body 11, a flue gas modulation plate 12, special-shaped star holes 13 and a main sprayer 14;

[0048] The flue gas modulation plate 12 is arranged inside the body 11, and the flue gas modulation plates 12 are arranged in a vertical array; the special-shaped star holes 13 are opened inside the flue gas modulation plate 12, and the special-shaped star holes 13 are arranged in an annular array. The flue gas passes through the flue gas modulation plate 12 from bottom to top and is evenly dispersed by the special-shaped star holes 13; the main sprayer 14 is arranged above the body 11, and the main sprayer 14 is used for spraying desulfurization on the dispersed flue gas.

[0049] The main sprayer 14 includes a transfer pipe 141 and a first spray head 142; the transfer pipes 141 are arranged in a vertical array; the first spray head 142 is arranged inside the transfer pipe 141, and the first spray heads 142 are arranged in an annular array; a secondary sprayer 15 is arranged inside the body 11, and the secondary sprayer 15 includes a water inlet pipe 151 and a second spray head 152; the water inlet pipes 151 are arranged in a vertical array; the second spray head 152 is arranged inside the water inlet pipe 151, and the second spray heads 152 are arranged in an annular array and are used for cleaning the special-shaped star holes 13 inside the flue gas modulation plate 12. A Venturi rectifying part 16 is arranged below the body 11, and the outlet of the Venturi rectifying part 16 is communicated with the flue gas modulation plate 12. A plurality of Venturi tubes are arranged inside the Venturi rectifying part 16, including a tower body 2. The lower end of the tower body 2 is provided with a desulfurization tower flue gas inlet 21, the upper end of the tower body 2 is provided with a desulfurization tower flue gas outlet 22, and a demister 23 is arranged at the top of the tower body 2. An efficient conditioning reactor is arranged between the desulfurization tower flue gas inlet 21 and the desulfurization tower flue gas outlet 22, and the efficient conditioning reactor is the efficient conditioning reactor according to any one of claims 1-3.

[0050] In this embodiment, the operation process of the device is that the flue gas enters the inside of the tower body 2 through the desulfurization tower flue gas inlet 21, the flue gas moves upward, passes through the arrangement of the Venturi rectifying part 16, enters the inside of the body 11, and the flue gas is dispersed through the special-shaped star holes 13. At this time, the lime slurry is sprayed out through the first spray head 142, and the lime slurry contacts the flue gas to achieve the purpose of desulfurizing the flue gas. After desulfurization is completed, the flue gas enters the inside of the demister 23 and then is discharged through the desulfurization tower flue gas outlet 22 to complete the desulfurization of the flue gas.

[0051] A plurality of special-shaped star holes 13 are distributed on the flue gas modulation plate 12 of the device. The opening ratio is 35-60% according to the gas velocity in the empty tower, the comprehensive aperture is 35-65 mm, and the maximum side length of the adjacent space of the openings does not exceed 35 mm. The following appendix Figures 2 to 3It is the approximate hole pattern of the flue gas conditioning plate 12, and the specific layout form will be determined according to the requirements of the desulfurization tower or other devices. From the actual effect, the larger the perimeter / area ratio of the hole pattern, the larger the contact area between the flue gas and the circulating liquid, the larger the conditioning coefficient, and the better the effect. For the special-shaped star hole 13, the perimeter area ratio is between 25% - 45%, that is, the contact and convection area between the flue gas and the circulating liquid is more than 3 times that of the tray, and the maximum side distance of the adjacent space of the opening does not exceed 35 mm. In the design, the connecting line of any blank plane left after the opening of the flue gas conditioning plate 12 is in the shape of an intermittent toothed connection, and there are more than four acute angles opposite to each other at each wider part. During use, it can greatly interfere with the accumulation of particulate matter through the disturbance of the slurry; at the same time, under the same empty tower flue gas velocity, the opening rate of this flue gas conditioning plate 12 is much higher than that of a normal tray. Therefore, in principle, this conditioning reactor has no liquid collection layer, and the perforation speed is lower than that of other types of rectifying or conditioning devices. The resistance of the reactor is only the perforation resistance of the conditioning plate. In the Venturi rectifying part 16 in the device, there are multiple Venturi tubes inside, and its pipeline is in the shape of gradually shrinking - gradually expanding. When the gas passes through, the flow velocity increases and the pressure decreases in the narrow part; while in the expanding part, the flow velocity slows down and the pressure recovers. This design can effectively reduce turbulence and energy loss, and improve the stability of gas flow, so that when the flue gas enters the inside of the body 11, it can ensure the stable flow of the flue gas and ensure the desulfurization efficiency.

[0052] Example 2:

[0053] An embodiment of the present invention discloses an efficient conditioning reactor and a desulfurization tower. According to the attached Figure 1 , 7 shown, it includes a reaction efficiency unit 1, and the reaction efficiency unit 1 includes a body 11, a flue gas conditioning plate 12, a special-shaped star hole 13 and a main sprayer 14; the flue gas conditioning plate 12 is arranged inside the body 11, and the flue gas conditioning plate 12 is arranged in a vertical array; the special-shaped star hole 13 is opened inside the flue gas conditioning plate 12, and the special-shaped star hole 13 is arranged in an annular array, and the flue gas passes upward through the flue gas conditioning plate 12 and is evenly dispersed by the special-shaped star hole 13; the main sprayer 14 is arranged above the body 11, and the main sprayer 14 is used for spraying desulfurization on the dispersed flue gas.

[0054] In this embodiment, after the lime slurry desulfurization is completed, it flows out from the inside of the reaction efficiency unit 1, and enters the inside of the sedimentation tank 31 under the guidance of the porous plate 32. The slurry flows towards the bottom of the sedimentation tank 31 under the guidance of the guide plate 33. During the flowing process, the solids inside the slurry precipitate to the bottom of the sedimentation tank 31 under the guidance of the guide plate 33. Due to the existence of the guide plate 33, the slurry will not stir up the solids, achieving the purpose of purifying the slurry. The function of the porous plate 32 is to prevent the slurry falling from a high place from affecting the precipitation of the slurry inside the sedimentation tank 31. And a low-frequency oscillation device is arranged inside the guide plate 33, which can ensure that the solids will not accumulate on the guide plate 33. The principle of the low-frequency oscillation device is that an eccentric block is arranged on the motor shaft, and the motor drives the eccentric block to rotate, thereby driving the guide plate 33 to vibrate to achieve the purpose of cleaning the guide plate 33.
