Technical Field

[0001] The utility model relates to the technical field of desulfurization and denitrification equipment, in particular to boiler desulfurization and denitrification equipment with dust removal function. Background Art

[0002] Desulfurization and denitrification equipment primarily utilizes chemical reactions to convert sulfur dioxide and nitrogen oxides in industrial waste gas into other harmless substances, thereby achieving the goal of purifying the air. Desulfurization and denitrification equipment is a very important piece of equipment in chemical engineering. Its main function is to reduce the concentration of sulfur dioxide and nitrogen oxides in industrial waste gas and flue gas, protecting the environment and human health.

[0003] According to a boiler flue gas dust removal, desulfurization and denitrification equipment disclosed in Chinese patent CN213555996U, the flue gas is desulfurized and denitrified. The second filter can play a filtering role to prevent impurities in the flue gas from falling into the alkaline solution in the shell. By opening the sealed door, the second filter can be cleaned, and the alkaline solution in the shell can be easily extracted and replaced.

[0004] After use, the device in the aforementioned patent requires manual cleaning of impurities on the top of the second filter, which increases the operator's workload. Furthermore, the impurities cannot be cleaned during operation, which can easily cause the second filter to become clogged, thereby reducing filtration efficiency. Therefore, we provide a boiler desulfurization and denitrification device with a dust removal function. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0024] like Figures 1 to 5 As shown, the boiler desulfurization and denitrification equipment with dust removal function described in this embodiment includes: an equipment box 1; a support leg 2 fixedly connected to the bottom of the equipment box 1; a material injection pipe 3 connected to the bottom right side of the equipment box 1; a sewage outlet 4 opened on the front of the equipment box 1; a sealing plate 5 clamped on the inner surface of the sewage outlet 4; an exhaust pipe 6 fixedly connected to the top of the equipment box 1; a clamping plate 7 fixedly connected to the inner wall of the equipment box 1; an activated carbon filter plate 8 clamped on the inner surface of the clamping plate 7; and an air intake pipe 10 fixedly connected to the right side of the equipment box 1.

[0026] The processing unit 91 includes a motor 911 fixedly connected to the right side of the equipment box 1, and the output end of the motor 911 is fixedly connected to a rotating tube 912. The outer wall of the rotating tube 912 is connected to a liquid storage cylinder 914 through a liquid guide tube 913. The outer wall of the liquid storage cylinder 914 is connected to a spray tube 915. The left end of the rotating tube 912 passes through the left side of the equipment box 1 and is provided with an annular groove 916. The inner surface of the annular groove 916 is rotatably connected to a mounting sleeve 917. The end of the mounting sleeve 917 away from the rotating tube 912 is fixedly sleeved on the top outer wall of the liquid extraction pipe 918. The bottom end of the liquid extraction pipe 918 is connected to a water pump 919 and passes through the left side of the equipment box 1. The water pump 919 is fixedly connected to the left side of the equipment box 1.

[0027] In this embodiment, a sealing ring is fixedly connected to the inner surface of the mounting sleeve 917 , and the sealing ring is sleeved at the connection between the liquid extraction tube 918 and the rotating tube 912 to improve the sealing of the connection and prevent water leakage.

[0028] Furthermore, the bottom end of the liquid extraction tube 918 is set below the filter plate 936, and the liquid is filtered by the filter plate 936 and then reused. Example 2

[0029] like Figures 1 to 5As shown, on the basis of Example 1, in the boiler desulfurization and denitrification equipment with dust removal function described in this embodiment, the transmission part 92 includes an outer rod 921 fixedly connected to the outer wall of the rotating tube 912, and the bottom of the outer rod 921 is movably sleeved with a T-shaped rod 922, and the top bottom of the T-shaped rod 922 is fixedly connected to a spring 923, and the bottom end of the spring 923 is fixedly connected to the inner bottom of the outer rod 921.

[0030] In this embodiment, the bottom end of the T-shaped rod 922 is in contact with the stop block 937 . The T-shaped rod 922 contacts the stop block 937 , thereby driving the stop block 937 to move. Example 3

[0031] like Figures 1 to 5 As shown, on the basis of Example 1, in the boiler desulfurization and denitrification equipment with dust removal function described in this embodiment, the cleaning part 93 includes a fixed plate 931 fixedly connected to the inner wall of the equipment box 1, and a movable groove 932 is opened on the side of the fixed plate 931. The inner surface of the movable groove 932 is slidably connected to a limiting guide rod 933, and the bottom of the limiting guide rod 933 is fixedly connected to a fixing rod 934, and the bottom of the fixed rod 934 is fixedly connected to a scraper 935, and a filter plate 936 is provided below the scraper 935.

[0032] In this embodiment, the bottom of the scraper 935 is arranged to contact the bottom surface of the filter plate 936, and the scraper 935 is used to clean impurities on the surface of the filter plate 936.

[0033] During actual operation, when this device is used, the treatment liquid is introduced into the bottom of the equipment box 1 through the injection pipe 3, and the water pump 919 is started to introduce the treatment liquid into the rotating tube 912 through the liquid suction pipe 918, and then introduced into the liquid storage cylinder 914 through the rotating tube 912 via the liquid guide pipe 913, and finally sprayed into the equipment box 1 through the spray pipe 915 to desulfurize and denitrify the flue gas introduced through the air intake pipe 10.

The T-shaped rod 922 can adjust its length according to the distance from the block 937 by utilizing the elasticity of the spring 923 to ensure that the bottom end of the T-shaped rod 922 is always in contact with the block 937, so that the block 937 is forced to drive the limiting guide rod 933 to slide forward in the movable groove 932. The limiting guide rod 933 drives the scraper 935 to slide forward through the fixed rod 934, and the scraper 935 is used to push the impurities filtered on the surface of the filter plate 936 to the sewage outlet 4, which can avoid clogging of the filter plate 936 and facilitate impurity cleaning without manual operation. When the scraper 935 moves to the sewage outlet 4, the T-shaped rod 922 is rotated upward, and the elasticity of the strong rib 938 can make the scraper 935 automatically reset, waiting for the next movement for cleaning.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
