Description

Technical Field

[0001] The utility model relates to the field of ammonia adding technology equipment for a power plant boiler reaction tank, in particular to an ammonia water adding device for a power plant boiler. Background Art

[0002] In existing power plant boiler reactors, the pH value of the water is usually adjusted by adding ammonia water to prevent acidic corrosion and protect metal equipment from damage, thereby extending the service life of the reactor and pipelines and ensuring the smooth progress of industrial production. The top cover of the existing power plant reactor is usually provided with an ammonia water addition hole for personnel to add ammonia water into the tank body. When ammonia water needs to be added to the tank body, personnel usually climb a ladder to the top of the tank body, then open the cap of the ammonia water bottle, and pour the ammonia water bottle into the tank body. However, since ammonia water has a certain volatility, in order to ensure the safety of personnel, personnel need to wear gas masks and masks before opening the cap, and then open the cap of the ammonia water bottle to pour the ammonia water. However, the overall operation is cumbersome, and even if personnel wear gas masks and masks, there is still a risk of contact with ammonia water.

[0003] To address the aforementioned technical issues and reduce the impact of contact between personnel and ammonia on their safety, the applicant designed an ammonia adding frame that can be snapped into the ammonia adding hole. The bottom of the ammonia adding frame is provided with a spiked end capable of puncturing the body of the ammonia bottle. Once the ammonia bottle is placed in the ammonia adding frame, the spiked end can puncture the body of the ammonia bottle, allowing the ammonia to flow into the tank. During the aforementioned ammonia adding process, personnel need to apply a certain amount of force when placing the ammonia bottle in the ammonia adding device to ensure that the spiked end can effectively puncture the bottle and release the ammonia. Furthermore, when the spiked end punctures the ammonia bottle, the ammonia may splash and volatilize, causing irritation and corrosion to the eyes, nose, and skin of personnel, thereby affecting the safety of the personnel's working environment. Utility Model Content

[0004] The utility model aims to provide an ammonia water adding device for a power plant boiler, which can reduce the impact of ammonia water splashing and volatilization on personnel health after the ammonia water bottle is punctured.

[0005] In order to solve the above technical problems, the specific solution adopted by the utility model is an ammonia water adding device for a power plant boiler: comprising an ammonia water dropping box, two horizontal flat plates arranged in the ammonia water dropping box, and a plurality of top tubes; the ammonia water dropping box can be clamped into the rectangular ammonia water adding hole on the top cover of the reaction tank, the upper end and the lower end of the ammonia water dropping box are both open, a support rod is respectively installed on the two opposite side walls above the ammonia water adding hole in the ammonia water dropping box, and a plurality of reset torsion springs are installed on any of the support rods, one end of the reset torsion spring rests on the inner wall of the corresponding ammonia water dropping box, and the other end is fixed to the bottom surface of one of the horizontal flat plates to keep the two horizontal flat plates in a horizontal closed state; a pull rope for pulling the horizontal flat plate to rotate and open is fixed to the bottom surface of one of the horizontal flat plates;

[0006] A plurality of support rods for carrying ammonia bottles are fixed in the opening at the lower end of the ammonia delivery box, and a plurality of top tubes are fixed on the support rods for piercing the bottle bodies of the ammonia bottles.

[0007] As another optimization solution for the above-mentioned ammonia water adding device for power plant boilers: a plurality of side support legs are provided on the periphery of the ammonia water delivery box to assist it in stably hanging in the ammonia water adding hole.

[0008] As another optimization solution for the above-mentioned ammonia water adding device for power plant boilers: the number of side support legs is four, and the four side support legs are respectively fixed to the middle outer periphery of the four side walls of the ammonia water delivery box.

[0009] As another optimization solution for the above-mentioned ammonia water adding device for power plant boiler: the upper end of the pull rope is fixed to the center point of the bottom surface of the horizontal plate, the lower end of the pull rope hangs down along the outer wall of the reaction tank, and the lower end of the pull rope is tied with a lead block.

[0010] As another optimization solution for the above-mentioned ammonia water adding device for power plant boilers: positioning rings for the pull rope to pass through are installed on the outer wall and the top cover of the reaction tank along the direction in which the pull rope is drooped.

[0011] As another optimization solution for the above-mentioned ammonia water adding device for a power plant boiler, the number of support rods is two, and the two support rods are arranged in a cross shape.

[0012] As another optimization solution for the above-mentioned ammonia water adding device for power plant boiler: nine top tubes are evenly distributed on the two support rods.

[0013] As another optimization solution for the above-mentioned ammonia water adding device for power plant boiler: both ends of the support rod are fixed to the side walls of the corresponding ammonia water delivery box through connecting short rods.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The ammonia delivery box of the present invention can be snapped into the ammonia adding hole opened on the top cover of the reaction tank. The two horizontal plates are in a horizontally closed state under the support of the corresponding reset torsion springs, which can support the ammonia bottle. When ammonia needs to be added, the person only needs to pull the pull rope remotely, and the pull rope drives the corresponding horizontal plate to rotate and open. The ammonia bottle that has lost its support falls onto the support rod under its own gravity. The multiple top tubes on the support rod can pierce the body of the ammonia bottle to flow out the ammonia and add it to the reaction tank. As the ammonia bottle falls onto the support rod, the two horizontal plates are reset to a horizontally closed state under the reaction force of the reset torsion spring. The two horizontally closed horizontal plates can block some of the ammonia that splashes when the top tubes pierce the body of the ammonia bottle. Compared with the existing ammonia adding frame, it can reduce the amount of ammonia added to the reaction tank that evaporates out of the tank body, thereby reducing the occurrence of ammonia splashing or affecting the health and work safety of personnel.

[0019] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. Parts that are not described in detail in the following embodiments of the present invention, such as the two horizontal plates maintaining a horizontal closed state under the support of corresponding reset torsion springs, should be immediately known to those skilled in the art or should be known to the prior art.

[0020] An ammonia water adding device for a power plant boiler, such as Figure 1-2 As shown, it includes an ammonia water delivery box 2, two horizontal flat plates 3 arranged in the ammonia water delivery box 2, and a plurality of top tubes 501. The ammonia water delivery box 2 can be clamped in the rectangular ammonia water addition hole 102 opened on the top cover 101 of the reaction tank. The shape of the ammonia water delivery box 2 is a rectangle that matches the shape of the ammonia water addition hole 102, so that the ammonia water delivery box 2 can be clamped in the ammonia water addition hole 102.

[0021] In addition, in order to further prevent the ammonia delivery box 2 from sliding down and falling into the reaction tank, a side support leg 201 is fixed to the middle of the outer periphery of each of the four side walls of the ammonia delivery box 2. One end of the side support leg 201 is fixed to the outer periphery of the corresponding side wall, and the other end is tilted toward the top cover 101 and rests on the upper end surface of the top cover 101 to ensure that the ammonia delivery box 2 is stably in the ammonia delivery hole 102.

[0022] The upper and lower ends of the ammonia solution delivery box 2 are both open. A support rod 301 is installed on the left and right opposite inner walls of the ammonia solution delivery box 2 above the ammonia solution addition hole 102. The two support rods 301 are arranged horizontally and parallel to the top cover 101. The two support rods 301 are fixed to the side walls of the ammonia solution delivery box 2 on the corresponding side by connecting short rods 302. A connecting short rod 302 is fixed to each end of each support rod 301. The connecting short rods 302 are arranged perpendicular to the support rods 301. One end of the connecting short rod 302 is fixed to one end of the corresponding support rod 301, and the other end is fixed to the inner wall of the ammonia solution delivery box 2 on the corresponding side, so that the support rods 301 are stably fixed to the ammonia solution delivery box 2. The connecting short rods 302 provide a certain installation gap between the support rods 301 and the side walls of the ammonia solution delivery box 2.

[0023] Each support rod 301 is fitted with two return torsion springs 303, evenly spaced apart. One end of the return torsion spring 303 presses against the inner wall of the corresponding ammonia solution delivery box 2. A slot is provided on the inner wall of the corresponding ammonia solution delivery box 2 for the end of the return torsion spring 303 to fit snugly into. The other end of the return torsion spring 303 is secured to the bottom surface of one of the horizontal plates 3 to maintain the horizontal position. The two horizontal plates 3, supported by the corresponding return torsion springs 303, are in a horizontally closed position and can support ammonia bottles of a certain weight or volume, preventing them from falling.

[0024] A pull rope 4 is fixed to the bottom surface of the horizontal plate 3 on the left side. The upper end of the pull rope 4 is fixed to the center point of the bottom surface of the horizontal plate 3. The lower end of the pull rope 4 passes through the through-hole set on the left wall of the ammonia solution delivery box 2 on the corresponding side and hangs down along the outer wall 1 of the reaction tank. A positioning ring 401 for the pull rope 4 to pass through is respectively provided on the upper end surface of the top cover 101 and the outer wall 1 of the reaction tank. A fixed pulley is also fixed to the outer wall 1 of the reaction tank below the corresponding positioning ring 401. The lower end of the pull rope 4 is wrapped around the fixed pulley once and then fixed to a lead block 402. The lead block 402 pulls the pull rope 4 in a hanging state, and a person can pull down the pull rope 4 by holding the lead block 402.

[0025] Two support rods 5 for supporting the ammonia bottles are fixed to the lower opening of the ammonia delivery box 2. These rods 5 are arranged vertically in a cross shape, with each end secured to the inner wall of the corresponding ammonia delivery box 2. Nine tip tubes 501 are evenly attached to the two support rods 5. The lower ends of these tip tubes 501 are fixed to a side wall facing the horizontal plate 3, while the upper tips of the tip tubes 501 face upward, facilitating the puncture of the ammonia bottles and allowing the ammonia to flow into the reaction tank.

[0026] When the ammonia bottle falls, the pull rope 4 can be loosened to allow the ammonia bottle to fall onto the support rod 5 and be punctured by the top tube 501 to splash ammonia. The two horizontal plates 3 are in a horizontal closed state under the action of the reset torsion spring 303, thereby achieving the addition of ammonia while avoiding the splashing or volatilization of ammonia and affecting people's health.

[0027] The process of adding ammonia water according to the present invention is as follows: first, a person places the ammonia water bottle on two horizontal flat plates 3, and then pulls down the pull rope 4. The left horizontal flat plate 3 rotates downward and opens under the pull of the pull rope 4. Then, the ammonia water bottle placed on the horizontal flat plate 3 loses its supporting force and falls onto the support rod 5 under the action of its own gravity. At the same time, the pull rope 4 is released, and the two horizontal flat plates 3 are restored to a horizontal closed state. The top tube 501 pierces the bottle body of the ammonia water bottle, and the ammonia water flows into the reaction tank from the hole in the bottle body.
