Description

Technical Field

[0001] The utility model relates to the field of flue gas desulfurization, in particular to a flue gas desulfurization spray tower. Background Art

[0002] During the spray desulfurization process, the by-product gypsum is easy to clog the nozzle, making it difficult to repair and replace parts. The desulfurization process needs to be stopped for replacement, and the operator needs to enter the tower for maintenance and replacement, which not only affects the efficiency but also wastes time. In addition, the flow rate of the flue gas is fast, and the flue gas is not dispersed evenly. A small part of the flue gas still fails to contact with the detergent for desulfurization, affecting the desulfurization efficiency of the flue gas. For this reason, the patent publication number CN219482183U proposes a spray tower for flue gas desulfurization, which pierces the gypsum for cleaning by setting a conical thorn into the nozzle.

[0003] In this way, although the gypsum blockage at the nozzle can be cleaned, the conical thorn is used for cleaning. Since the conical thorn is sharp at one end and thick at the other end, after piercing the gypsum blockage, a ring-shaped gypsum will still remain on the nozzle, and the cleaning effect is not good. In addition, the nozzle will be blocked when the nozzle is deblocked at the same time, thereby affecting the desulfurization effect. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a flue gas desulfurization spray tower.

[0005] The technical solution of the utility model is: a flue gas desulfurization spray tower, comprising a base plate, a spray tower body, a water tank, a water pump, a water outlet pipe, a water suction pipe, an annular water pipe and a nozzle, the spray tower body is installed on the left side of the top of the base plate, the water tank is installed on the right side of the top of the base plate, the water pump is installed on the water tank, the water outlet pipe is installed on the top of the water pump, the water suction pipe is installed at the bottom of the water pump, the water suction pipe runs through the water tank and is located inside the water tank, two annular water pipes are arranged up and down inside the spray tower body, a plurality of nozzles are arranged on the annular water pipes, the right ends of the two annular water pipes are connected with the water outlet pipe, and also include a lifting component and a cleaning component, the lifting component is arranged inside the spray tower body, the cleaning component for cleaning the nozzles is arranged on the lifting component, and the lifting component is used to push the cleaning component to clean the nozzles at the two annular water pipes respectively.

DETAILED DESCRIPTION

[0018] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0019] Embodiment: A flue gas desulfurization spray tower, such as Figure 1-Figure 4As shown, it includes a bottom plate 1, a spray tower body 101, a water tank 102, a water pump 103, a water outlet pipe 104, a water suction pipe 105, an annular water pipe 2 and a nozzle 21. The spray tower body 101 is installed on the left side of the top of the bottom plate 1 by bolts, the water tank 102 is installed on the right side of the top of the bottom plate 1 by bolts, the water pump 103 is installed on the water tank 102 by bolts, the top of the water pump 103 is connected to the water outlet pipe 104 by a flange, the bottom of the water pump 103 is connected to the water suction pipe 105 by a flange, and the water suction pipe 105 is connected to the water outlet pipe 104 by a flange. The through water tank 102 is located inside the spray tower body 101. Two annular water pipes 2 are fixedly arranged in the upper and lower parts of the spray tower body 101. Multiple nozzles 21 are arranged on the annular water pipes 2. The right ends of the two annular water pipes 2 are connected to the water outlet pipe 104. The spray tower body 101 also includes a lifting component and a cleaning component. The lifting component is arranged inside the spray tower body 101. The lifting component is provided with a cleaning component for cleaning the nozzles 21. The lifting component is used to push the cleaning component to clean the nozzles 21 at the two annular water pipes 2 respectively.

[0020] like Figure 2 and Figure 3 As shown, the lifting assembly includes a fixed seat 31, a partition plate 32 and an electric push rod 33. Two pairs of fixed seats 31 are symmetrically fixedly arranged inside the spray tower body 101, and a partition plate 32 is slidably arranged between the two fixed seats 31 at the same height. Two pairs of electric push rods 33 are symmetrically installed inside the spray tower body 101, and the two electric push rods 33 at the same height are fixedly connected to the two sides of the bottom of the adjacent partition plate 32 respectively.

[0021] like Figure 3 and Figure 4 As shown, the cleaning assembly includes a mounting seat 41, a brush rod 42, a cone head 43 and a motor 44. A plurality of mounting seats 41 are fixedly arranged at intervals on the two partition plates 32. The number of the mounting seats 41 is the same as the nozzle 21, and a nozzle 21 is correspondingly arranged directly above each mounting seat 41. A brush rod 42 is rotatably arranged on the upper part of the mounting seat 41, and a cone head 43 for piercing plaster is fixedly arranged on the top of the brush rod 42. A motor 44 is installed on the mounting seat 41 by bolts, and the output shaft end of the motor 44 is fixedly connected to the bottom end of the adjacent brush rod 42.

[0022] When in use, the staff injects sodium hydroxide solution into the water tank 102 and starts the water pump 103. The water pump 103 pumps the sodium hydroxide solution into the water outlet pipe 104 through the water pumping pipe 105, and sprays it out from the nozzle 21 through the two annular water pumps 103 to desulfurize the flue gas in the spray tower body 101. When the nozzle 21 is blocked, the staff first starts the two electric push rods 33 and the motor 44 on the upper side. The electric push rod 33 pushes the partition plate 32 to move upward, so that the cone head 43 penetrates into the gypsum in the nozzle 21. When the cone head 43 moves upward, When the nozzle 21 is pierced, the motor 44 drives the brush rod 42 to rotate, thereby thoroughly cleaning the gypsum attached to the nozzle 21. After the nozzle 21 at the upper annular water pipe 2 is cleaned, the telescopic rod of the electric push rod 33 retracts to move the partition plate 32 downward and reset. At this time, the staff can restart the electric push rod 33 and the motor 44 on the lower side to clean the nozzle 21 at the lower annular water pipe 2. In this way, it can be ensured that a group of nozzles 21 are working normally, and the flue gas denitrification work is not affected when the nozzles 21 are cleaned.

[0023] like Figure 2 As shown, a filter block 5 is provided at the end of the water suction pipe 105 . The filter block 5 can remove impurities in the sodium hydroxide solution sucked into the water suction pipe 105 to prevent the impurities from clogging the nozzle 21 .

[0024] like Figure 2 and Figure 3 As shown, a plurality of through holes are provided at intervals on the partition plate 32. The provision of the through holes can block the sodium hydroxide solution so that it can have better contact with the flue gas without affecting the normal rise of the flue gas.

[0025] The bristles on the brush rod 42 are made of nylon, so as to powerfully remove the plaster blockage at the nozzle 21 without causing damage to the nozzle 21 .

[0026] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
