Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of denitration, in particular to a denitration tower structure. Background Art
[0002] In order to prevent excessive NOx pollution from being generated after coal combustion in boilers, coal should be denitrated. It is divided into denitration before combustion, denitration during combustion, and denitration after combustion. There are two main flue gas denitration technologies: dry method and wet method. The wet method is to atomize the reaction solution in the denitration tower through the nozzle, and then react with NOx and other harmful gases.
[0003] The existing denitrification equipment has the following disadvantages when in use:
[0004] The use of nozzles to spray out water mist makes it uneven, which will cause the reaction solution and flue gas to not react fully, resulting in incomplete denitrification and secondary pollution to the environment. In addition, the waste water from the solution after the reaction is not treated and recycled, resulting in a waste of resources.
[0005] Flue gas is usually directly introduced into the equipment through the air inlet pipe for cleaning, but there are many impurities in the flue gas. If the flue gas is not preliminarily treated in advance and is directly introduced into the denitrification tower, it will bring a heavy processing burden to the denitrification tower. In view of this, we propose a denitrification tower structure. Utility Model Content

If the flue gas is not preliminarily treated in advance, it will bring a heavy processing burden to the denitrification tower. The specific scheme is as follows: It includes a denitrification tank 1 and an air intake pipe 4, the denitrification tank 1 and the air intake pipe 4 are fixedly installed, and the denitrification tank 1 and the air intake pipe 4 are internally connected. Among them, the interior of the air intake pipe 4 can facilitate the waste gas to be treated to enter the denitrification tank 1, and an air outlet 2 and a drain 3 are provided on the upper and lower sides of the denitrification tank 1.
[0024] See also Figure 1 and Figure 2 A support plate 5 is fixedly mounted on the outside of the denitration tank 1, and the support plate 5 can facilitate the support of other components. A driving component 6 is provided on the side of the support plate 5 corresponding to the air intake pipe 4;

A rotating shaft 61 is provided on the output shaft of the driving motor 60, and a toggle block 67 is provided on the rotating shaft 61.

[0026] Furthermore, a sliding seat 62 is movably sleeved below the rotating shaft 61, a spiral groove 621 is provided inside the sliding seat 62, and a toggle block 67 is movably connected inside the spiral groove 621, and the spiral groove 621 is a closed groove. Since the toggle block 67 always slides inside the spiral groove 621, after the toggle block 67 moves in a circular manner, the sliding seat 62 can move upward or downward along the center line direction of the rotating shaft 61.
[0027] See also Figure 2 , Figure 3 and Figure 4 A piston cylinder 64 is provided between the rotating shaft 61 and the denitrification tank 1, an air inlet pipe is provided on the piston cylinder 64, a one-way valve is provided on the air inlet pipe, a piston rod 66 is movably inserted under the piston cylinder 64, a plug-in rod 63 is movably inserted on the air inlet pipe 4, and the plug-in rod 63 and the piston rod 66 are both fixedly mounted on the sliding seat 62. When the sliding seat 62 moves upward or downward, the plug-in rod 63 and the piston rod 66 can be driven to produce the same movement. When the sliding seat 62 moves upward, the plug-in rod 63 and the piston rod 66 move upward, and the piston rod 66 moves upward and is inserted into the piston cylinder 64, so that the gas inside the piston cylinder 64 can be ejected from the piston cylinder 64.
[0028] In this example, a filter screen 41 is fixedly installed inside the air intake pipe 4, and the filter screen 41 can facilitate the dust filtering in the exhaust gas, so that a fixed shaft 42 is fixedly installed in the middle of the filter screen 41, and a scraper 43 is passed between the fixed shaft 42 and the plug rod 63, and the scraper 43 and the fixed shaft 42 and the plug rod 63 are all rotatably connected; the piston rod 66 and the rotating shaft 61 are parallel to each other, and the length of the piston rod 66 is less than the length of the rotating shaft 61. The piston rod 66 and the plug rod 63 are parallel to each other, and the piston rod 66 and the plug rod 63 are respectively arranged on the left and right sides of the rotating shaft 61.

And through the setting of the drive assembly 6, the scraper 43 can be made to move in a circular manner on the fixed shaft 42, and the end surface dust of the filter screen 41 can be cleaned by the scraper 43, which further ensures the filtering effect of the filter screen 41.
[0029] Furthermore, a water ring cavity 8 and a jet ring 7 are provided inside the denitration tank 1, and an external pipe 82 is connected to the water ring cavity 8, and the external pipe 82 can facilitate the discharge of external water supply into the water ring cavity 8.

When the sliding seat 62 moves upward, the piston rod 66 moves upward, and the piston rod 66 moves upward and is inserted into the piston cylinder 64, so that the gas inside the piston cylinder 64 can be sprayed out from the piston cylinder 64. Through the connection of the hose 65, the gas can pass through the hose 65 into the jet ring 7, and then enter the jet pipe 71, so that the gas is sprayed out through the jet end 72, which can provide a blowing force from the outside to the inside for the solution sprayed downward, so that the sprayed solution is wavy, further increasing the contact area between the solution and the flue gas, and further increasing the flue gas denitrification treatment effect.
[0031] Working principle: When this denitrification tower structure is used, the flue gas to be treated enters the denitrification tank 1 through the air inlet pipe 4. During this process, the denitrification treatment solution sprayed from the water outlet nozzle 81 on the water ring cavity 8 can treat the flue gas; and after the drive motor 60 is turned on, the rotating shaft 61 can be rotated, so that the toggle block 67 can move in a circular motion. After the toggle block 67 moves in a circular motion, the sliding seat 62 can move upward or downward along the center line direction of the rotating shaft 61; when the sliding seat 62 moves upward or downward, it can drive the plug rod 63 and the piston rod 66 to produce the same movement. When the sliding seat 62 moves upward, the plug rod 63 and the piston rod 66 move upward, and the piston rod 66 moves upward to be inserted into the piston cylinder 64, the gas inside the piston cylinder 64 can be ejected from the piston cylinder 64, and through the connection of the hose 65, the gas can enter the jet ring 7 through the hose 65, and then enter the jet pipe 71, so that the gas is ejected through the jet end 72, which can provide a blowing force from the outside to the inside for the solution sprayed downward, so that the sprayed solution is wavy, further increasing the contact area between the solution and the flue gas, and further providing the flue gas denitrification treatment effect; at the same time, through the downward movement of the plug-in rod 63 and the connection of the scraper 43, the scraper 43 can be made to move in a circular shape on the fixed shaft 42, and the dust on the end face of the filter 41 is cleaned by the scraper 43, thereby further ensuring the filtering effect of the filter 41.
