Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a denitrification device. Background Technology

[0002] Denitrification equipment refers to equipment used to reduce or remove nitrogen oxides in flue gas. Nitrogen oxides are an important environmental pollutant, mainly originating from combustion processes in industrial production and transportation. The main function of denitrification equipment is to convert nitrogen oxides in flue gas into harmless or less harmful substances, such as nitrogen, water vapor, or carbon dioxide, through chemical or physical methods, thereby reducing or eliminating their impact on the environment and human health.

[0003] Existing denitrification equipment includes a tower body, a demister layer assembly, a riser cap assembly, several spray layer assemblies, and several packing layer assemblies installed within the tower body. The spray layer assembly comprises a main spray network, several branch spray pipes installed on the main network, and nozzles mounted on each branch pipe. Currently, the nozzles are connected to the branch pipes via threaded connections. Given that a large number of nozzles need to be installed within a single denitrification unit, and that the threaded fastening method requires tightening each turn individually, insufficient tightening can easily lead to leaks. This installation method is not only labor-intensive but also poses a risk of leakage due to worker negligence. Therefore, this improved solution was developed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a denitrification device that enables convenient nozzle installation, thereby reducing installation workload and minimizing potential installation leakage risks.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a denitrification device, comprising a tower body, a demister layer group, a gas lifting cap group installed in the tower body, and several spray layer groups and several packing layer groups. The spray layer group includes a main spray network, several spray branch pipes installed in the main spray network, and several nozzles. Each nozzle is connected to each spray branch pipe with an insertion sealing structure. Each spray branch pipe is equipped with a limiting member. The limiting member has a limiting state and a non-limiting state for cooperating with the spray branch pipe to limit the insertion sealing structure to be in the insertion sealing state. The limiting member is connected with a locking member to lock the limiting member in the limiting state.

[0006] By adopting the above technical solution, during nozzle installation, the nozzle is inserted into the spray branch pipe through a designed plug-in sealing structure, forming a plug-in seal between the two. Then, a limiting component is installed on the spray branch pipe to limit the plug-in sealing structure to its plug-in sealed position. A locking component is then installed on the limiting component to lock it in its limited position. This completes the fixed installation of the nozzle on the spray branch pipe. This installation method eliminates the need for tightening each turn and avoids the risk of leakage due to insufficient tightening force, thus achieving convenient nozzle installation, reducing installation workload, and minimizing the risk of installation leaks.

[0007] The further configuration includes: the insertion sealing structure includes an insertion tube fixedly disposed on the nozzle and used for insertion into the spray branch pipe, and a sealing ring disposed between the insertion tube and the spray branch pipe.

[0008] By adopting the above technical solution, the pipe is inserted into the spray branch pipe to form a plug-in assembly between the spray branch pipe and the nozzle, and then the sealing ring is set to ensure the sealing between the two.

[0009] The further configuration is as follows: the sealing ring is installed inside the spray branch pipe, a compression gap is formed between the nozzle and the spray branch pipe to allow the nozzle to reciprocate along the insertion direction, and the insertion tube is inserted into the spray branch pipe and cooperates with the compression gap to apply a clamping force to the sealing ring.

[0010] By adopting the above technical solution, the sealing ring is placed inside the spray branch pipe to protect it and extend its service life. Furthermore, the designed compression gap ensures the sealing ring is always under compression, guaranteeing a tight seal between the nozzle and the spray branch pipe.

[0011] The limiting member is further configured as follows: the limiting member includes a limiting connecting section that spans above the spray branch pipe, two limiting feet that connect the two ends of the limiting connecting section and extend downward toward the nozzle, and a limiting part disposed on each limiting foot. The limiting part is attached to the nozzle to limit the movement of the nozzle away from the spray branch pipe. The limiting member is made of elastic material to give the two limiting feet the movement toward or away from each other.

[0012] By adopting the above technical solution, the two limiting feet move towards or away from each other to facilitate the assembly of the limiting component. The two limiting feet moving towards each other allow the limiting part to be attached to the bottom of the nozzle, thereby restricting the movement of the nozzle towards the opposite spray branch pipe, thus achieving the limiting purpose.

[0013] The locking element is further configured as follows: the locking element is a locking sleeve fitted onto the outer ring of the two limiting feet, and each limiting foot has a limiting block on its outer peripheral wall that restricts the downward movement of the locking sleeve.

[0014] By adopting the above technical solution, the locking sleeve restricts the opposite movement of the two limiting feet, ensuring that the two limiting parts are always engaged below the nozzle, thereby achieving the locking purpose. The limiting block prevents the locking sleeve from separating from the limiting feet, ensuring that the locking sleeve remains in a locked state.

[0015] The setting is further configured such that the limiting block is positioned near the lower end of the limiting foot.

[0016] By adopting the above technical solution, the locking sleeve is placed in the most effective locking position, thereby ensuring the locking force.

[0017] The setting is further configured such that the cross-sectional shape of the limiting foot is an arc shape adapted to the shape of the outer peripheral wall of the spray branch pipe.

[0018] By adopting the above technical solution, the arc-shaped structure can better prevent the horizontal movement of the limiting foot, ensuring that it is in the most effective limiting position.

[0019] The configuration is further defined as follows: the packing layer group includes a packing support beam and a regular packing layer disposed above the packing support beam. The regular packing layer is composed of several hexagonal regular packing blocks assembled together. The tower body is provided with a manhole corresponding to the position of each packing layer group.

[0020] By adopting the above technical solution, and by setting the structured packing layer as a modular structured packing block, after the entire tower body is assembled, the structured packing blocks can be installed one by one into the tower body through the manhole, which provides better protection for the installed structured packing layer and avoids damage caused by installing the structured packing layer first.

[0021] In summary, this utility model has the following beneficial effects: it enables convenient installation of the nozzle, thereby reducing the amount of installation work and lowering the potential for installation leakage. Attached Figure Description
