Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization equipment, in particular to a boiler desulfurization tower with reduced blockage. Background Art

[0002] In the existing boiler desulfurization technology, the desulfurization tower is a key treatment equipment, which is mainly used to remove sulfur oxides from boiler exhaust gas to reduce air pollution. However, during the operation of the traditional boiler desulfurization tower, the change of wind pressure in the tower may cause the water level of the desulfurized water to be unstable, resulting in the contact of the liquid surface with the steam-water separator plate, which not only affects the desulfurization efficiency, but also may cause the steam-water separator to be blocked. When the steam-water separator is blocked, it will seriously affect the desulfurization effect and the stable operation of the entire system.

[0003] To solve this problem, existing technologies usually rely on complex control systems to monitor and adjust wind pressure and liquid level, but these methods not only increase operating costs, but are also difficult to accurately control in actual operations. Therefore, developing a new type of boiler desulfurization tower that reduces the risk of blockage has become an important research direction in the field of desulfurization technology. Utility Model Content

[0004] The purpose of the utility model is to provide a boiler desulfurization tower with reduced blockage, so as to solve the problem that during the operation of the traditional boiler desulfurization tower proposed in the above background technology, the water level of the desulfurized water may be unstable due to the change of wind pressure in the tower, thereby causing the liquid surface to contact with the steam-water separation plate, which not only affects the desulfurization efficiency but also may cause blockage of the steam-water separator.

[0005] To achieve the above-mentioned purpose, the utility model provides a boiler desulfurization tower with reduced blockage, including a cooling tower, one side of the cooling tower is connected to a purification tower through a connecting pipe, a steam-water separation chamber is installed on the top of the purification tower, and the steam-water separation chamber, the interior of the steam-water separation chamber is respectively provided with an upper steam-water separation plate and a lower steam-water separation plate from top to bottom, and protrusions are symmetrically installed at the lower part of the interior of the steam-water separation chamber, and an inclined flue gas channel is formed between the protrusions.

[0006] Preferably, a cooling water inlet is installed at the top of the cooling tower, and a flue gas inlet is provided at an upper portion of one side of the cooling tower.

[0007] Preferably, a purified water inlet is provided on one side outer wall of the purification tower, and a smoke exhaust port is provided on one side of the upper portion of the steam-water separation chamber.

[0008] Preferably, the outer wall of the cooling tower is provided with a first manhole, and the outer wall of the purification tower is provided with a second manhole.

[0009] Preferably, a first drain outlet is provided at the bottom of the cooling tower, and a second drain outlet is provided at the bottom of the purification tower.

[0010] Preferably, a sedimentation bin is installed at the bottom of the middle section of the connecting pipe, and a cleaning cover is installed on one side of the sedimentation bin.

[0011] Preferably, a flow equalizing plate is installed at the upper part of the cooling tower near the cooling water inlet.

[0012] Preferably, a turbulence generator is installed in the middle of the purification tower, and an inclined baffle is installed near the end of the connecting pipe inside the purification tower.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the boiler desulfurization tower that reduces clogging, the risk of clogging of the steam-water separator is significantly reduced through structural optimization and functional innovation, and the desulfurization efficiency and equipment operation stability are improved. Specifically, the design of the desulfurization tower adopts a hierarchical treatment method. The high-temperature flue gas is first cooled by the cooling tower, and then deep desulfurization is carried out by the purification tower. Finally, the steam-water separation chamber efficiently separates the flue gas and water, and the water generated by turbulence is blocked by the setting of convex blocks to prevent water from contacting the upper steam-water separation plate and the lower steam-water separation plate. This process design not only improves the desulfurization effect, but also effectively prevents the problem of contact between the desulfurization liquid surface and the steam-water separation plate caused by changes in wind pressure in the tower, thereby reducing the possibility of clogging of the steam-water separator.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a boiler desulfurization tower with reduced blockage, such as Figure 1-Figure 3 As shown, it includes a cooling tower 1, one side of the cooling tower 1 is connected to the purification tower 2 through a connecting pipe 4, and a steam-water separation chamber 3 is installed on the top of the purification tower 2. The steam-water separation chamber 3, the interior of the steam-water separation chamber 3 is respectively provided with an upper steam-water separation plate 32 and a lower steam-water separation plate 33 from top to bottom, and protrusions 34 are symmetrically installed at the lower part of the interior of the steam-water separation chamber 3, and an inclined flue gas channel is formed between the protrusions 34. The inclined flue gas channel can prevent water from splashing upwards, thereby preventing the liquid surface from being unstable when turbulence occurs, causing contact with the upper steam-water separation plate 32 and the lower steam-water separation plate 33.

[0022] In this embodiment, a cooling water inlet 11 is installed on the top of the cooling tower 1 for the entry of cooling water, and a smoke inlet 12 is provided on the upper part of one side of the cooling tower 1 for the entry of smoke.

[0023] Specifically, a purified water inlet 22 is provided on one side of the outer wall of the purification tower 2 for the entry of purified water, and a smoke exhaust port 31 is provided on one side of the upper portion of the steam-water separation chamber 3 for the exhaust of smoke.

[0024] Furthermore, a first manhole 13 is provided on the outer wall of the cooling tower 1, and a second manhole 21 is provided on the outer wall of the purification tower 2, so as to facilitate workers to enter for maintenance.

[0025] Furthermore, a first drain port 14 is provided at the bottom of the cooling tower 1, and a second drain port 24 is provided at the bottom of the purification tower 2, so as to facilitate the discharge of cooling water.

[0026] Furthermore, a sedimentation bin 41 is installed at the bottom of the middle section of the connecting pipe 4 to settle some impurities to avoid blockage in the connecting pipe 4. A cleaning cover plate 42 is installed on one side of the sedimentation bin 41 to facilitate cleaning of the sedimentation bin 41.

[0027] Furthermore, a flow equalizing plate 15 is installed at the upper part of the cooling tower 1 near the cooling water inlet 11 to ensure that the cooling water falls evenly after descending and fully contacts with the flue gas.

[0028] Furthermore, a turbulence generator is installed in the middle of the purification tower 2 , and an inclined baffle 23 is installed inside the purification tower 2 near the end of the connecting pipe 4 to prevent impact when water flows into the purification tower 2 .

[0029] When the boiler desulfurization tower with reduced blockage of the utility model is used, first, the flue gas enters the cooling tower 1 through the flue gas inlet 12 of the cooling tower 1. At the same time, cooling water enters the cooling tower 1 through the cooling water inlet 11, and falls evenly under the action of the flow equalizer 15, fully contacting with the flue gas, thereby preliminarily cooling the high-temperature flue gas.

[0030] Then, the flue gas after preliminary cooling enters the purification tower 2 through the connecting pipe 4. In the middle section of the connecting pipe 4, some impurities in the flue gas will settle in the settling bin 41 to avoid blockage in the connecting pipe 4. The settling bin 41 can be cleaned regularly by opening the cleaning cover 42.

[0031] Then, the flue gas enters the purification tower 2 and reacts with the purified water entering through the purified water inlet 22, thereby removing sulfur oxides in the flue gas. In the purification tower 2, the turbulence generator will enhance the mixing effect of the purified water and the flue gas, thereby improving the desulfurization efficiency. At the same time, the inclined baffle 23 can prevent excessive impact when the water flow enters the purification tower 2.

[0032] Finally, the treated flue gas enters the steam-water separation chamber 3. In the steam-water separation chamber 3, the upper steam-water separation plate 32 and the lower steam-water separation plate 33 can effectively separate the water in the flue gas. The inclined flue gas channel formed between the protrusions 34 can prevent the water flow from splashing upward, ensure the stability of the liquid level, and avoid unnecessary contact with the upper steam-water separation plate 32 and the lower steam-water separation plate 33. The separated flue gas is finally discharged through the exhaust port 31.

[0033] During the whole process, the bottom of the cooling tower 1 and the purification tower 2 are provided with drains (the first drain 14 and the second drain 24) to facilitate the discharge of the treated water. At the same time, the outer walls of the cooling tower 1 and the purification tower 2 are respectively provided with the first manhole 13 and the second manhole 21 to facilitate workers to enter for inspection and maintenance.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
