Description

Technical Field

[0001] This application relates to the field of storage pipes, and more specifically, to a hazardous materials storage tank. Background Technology

[0002] Hazardous materials include flammable, explosive, and corrosive chemicals. Ammonia is an important chemical reagent widely used in chemical, agricultural, and pharmaceutical fields. However, due to its strong corrosiveness and irritant properties, its storage and handling require extra care. When storing ammonia, because ammonia is volatile, a small amount of ammonia gas may be present in the storage tank, so it is necessary to pay attention to the tank pressure.

[0003] The utility model patent with authorization announcement number CN221317728U discloses an ammonia storage tank device. The ammonia storage tank device includes a storage tank body, and a support base is symmetrically fixedly installed at the bottom of the storage tank body. The opening and closing of the exhaust pipe is realized through a transmission mechanism to quickly carry out the exhaust work and avoid the danger caused by excessive internal pressure in the storage tank.

[0004] In the above scheme, in order to relieve the internal pressure of the storage tank, an exhaust valve is set on the tank to release excess ammonia. However, ammonia is toxic and corrosive. Directly releasing it into the external environment will affect the external environment, and if inhaled by the human body, it will also affect the human body. Therefore, we propose a hazardous materials storage tank. Summary of the Invention

[0005] To overcome the above shortcomings, this application provides a hazardous materials storage tank, which aims to improve the problem that the direct discharge of ammonia into the external environment in the above scheme can easily cause environmental impact.

[0006] This application provides a hazardous materials storage tank, including a storage tank body, a pressure relief component connected to the storage tank body, a filter pipe connected to the outlet end of the pressure relief component, an exhaust hood threadedly connected to the filter pipe, and an activated carbon adsorption component installed on one side wall of the exhaust hood, the activated carbon adsorption component being correspondingly arranged with the outlet end of the pressure relief component.

[0007] In one specific implementation, the activated carbon adsorption assembly includes an assembly tube with one end open. A positioning rod is fixedly installed on the side wall of one end of the assembly tube, and a plurality of activated carbon filter blocks are slidably sleeved on the positioning rod. The plurality of activated carbon filter blocks are slidably disposed inside the assembly tube, and a plurality of air outlets are opened on the outer wall of the assembly tube.

[0008] In one specific implementation, a limiting block is fixedly installed on the outer wall of the positioning rod, and several activated carbon filter blocks are slidably sleeved on the limiting block.

[0009] In one specific implementation, a common pad is provided between two adjacent activated carbon filter blocks, and several of the pads are slidably sleeved on the positioning rod and the limiting block.

[0010] In one specific implementation, each of the activated carbon filter blocks is provided with a number of through holes, and adjacent through holes are staggered.

[0011] In one specific implementation, a locking screw is fixedly installed on one side wall of the positioning rod, and a locking nut is threaded onto the locking screw, which presses against one side of the activated carbon filter block.

[0012] In one specific implementation, a positioning seat is fixedly installed on the inner wall of the filter pipe, and a through opening is provided on the positioning seat. One end of the assembly pipe is in contact with the positioning seat, and a connecting screw is fixedly installed on the side wall of one end of the assembly pipe. A nut is fixedly installed on the side wall of one end of the exhaust hood, and the connecting screw is threadedly connected to the nut.

[0013] In one specific implementation, the exhaust hood is threaded onto the filter pipe, and the exhaust hood has a plurality of exhaust ports, the inner walls of which are each equipped with a dustproof net.

[0014] The beneficial effects of this application are as follows: By connecting a pressure relief component to the storage tank body, and connecting the outlet end of the pressure relief component to a filter pipe, an exhaust hood is threaded onto the outlet end of the filter pipe, and an assembly pipe is installed at one end of the exhaust hood. Several activated carbon filter blocks are installed inside the assembly pipe, thereby discharging excess ammonia gas from the storage tank body through the pressure relief component. The ammonia gas enters the assembly pipe inside the filter pipe, and after being adsorbed and filtered by several activated carbon filter blocks, it is discharged into the outside through the exhaust hood, thereby achieving the purpose of purification and emission, and thus avoiding impact on the external environment.

Detailed Implementation

[0018] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0019] Please see Figure 1-5 This application provides a hazardous materials storage tank, including a storage tank body 10. The specific structure of the storage tank body 10 is prior art. The storage tank body 10 is connected to existing pressure gauges and other equipment. A pressure relief assembly 20 is connected to the storage tank body 10. The outlet end of the pressure relief assembly 20 is connected to a filter pipe 30. The pressure relief assembly 20 includes a pipe and a pressure relief valve. The pressure relief valve is connected to the storage tank body 10 through the pipe, and the filter pipe 30 is connected to the outlet end of the pressure relief valve. Furthermore, the filter pipe 30 and the pressure relief valve are connected by a flange structure. An exhaust hood 40 is threaded onto the filter pipe 30. An activated carbon adsorption assembly 50 is installed on one side wall of the exhaust hood 40. The activated carbon adsorption assembly 50 is correspondingly set to the outlet end of the pressure relief assembly 20. When set up, the activated carbon adsorption assembly 50 is located inside the filter pipe 30, so that the discharged ammonia gas passes through the activated carbon adsorption assembly 50, thereby achieving the purpose of purification and emission.

[0020] See Figure 3 and 5The activated carbon adsorption assembly 50 includes an assembly tube 510, one end of which is open and corresponds to the outlet end of a pressure relief valve. A positioning rod 520 is fixedly installed on the side wall of one end of the assembly tube 510, and several activated carbon filter blocks 530 are slidably sleeved on the positioning rod 520. The activated carbon filter blocks 530 are all slidably disposed inside the assembly tube 510. Several air outlets 540 are opened on the outer wall of the assembly tube 510. In specific configuration, there is air flow space between two adjacent activated carbon filter blocks 530, allowing ammonia gas to pass through the activated carbon filter blocks 530. The air outlets 540 are located at one end of the assembly tube 510, allowing the filtered gas to pass through the air outlets 540. The activated carbon filter blocks are discharged into the filter pipe 30 and then through the exhaust hood 40. Furthermore, a limiting block 550 is fixedly installed on the outer wall of the positioning rod 520. Several activated carbon filter blocks 530 are slidably sleeved on the limiting block 550. It should be noted that a through hole is opened in the center of the activated carbon filter block 530, and a limiting groove is opened on the inner wall of the through hole. The through hole is sleeved on the positioning rod 520, and the limiting groove is sleeved on the limiting block 550 to achieve the purpose of limiting the activated carbon filter block 530 and prevent the activated carbon filter block 530 from rotating in the assembly pipe 510. In addition, the positioning rod 520 has a T-shaped cross section, so that one end of the rightmost activated carbon filter block 530 abuts against the positioning rod 520.

[0021] See Figure 3 A single pad 560 is provided between two adjacent activated carbon filter blocks 530. Several pads 560 are slidably fitted onto the positioning rod 520 and the limiting block 550. Similarly, a through hole is provided in the center of each pad 560, and a limiting groove is provided on the inner wall of the through hole. The through hole is fitted onto the positioning rod 520, and the limiting groove is fitted onto the limiting block 550. By providing a single pad 560 between two adjacent activated carbon filter blocks 530, the two adjacent activated carbon filter blocks 530 are positioned... The pad 560 is designed to allow airflow space between adjacent activated carbon filter blocks 530, enabling ammonia to flow within this space. Furthermore, each activated carbon filter block 530 has several through holes 570, which are staggered. Ammonia passes through these through holes 570 to achieve ammonia filtration. The staggered arrangement of the through holes 570 on adjacent sides can alter the ammonia flow path, thereby enhancing the contact effect between ammonia and the activated carbon filter blocks 530.

[0022] See Figure 3 and 5A locking screw 60 is fixedly installed on one side wall of the positioning rod 520. A locking nut 610 is threaded onto the locking screw 60. The locking nut 610 presses against one side of the activated carbon filter block 530. Specifically, after several activated carbon filter blocks 530 are installed on the positioning rod 520, the locking nut 610 is connected to the locking screw 60, thereby fixing several activated carbon filter blocks 530 through the locking nut 610.

[0023] See Figure 3 and 4 A positioning seat 310 is fixedly installed on the inner wall of the filter pipe 30. A through-hole 320 is provided on the positioning seat 310. One end of the assembly pipe 510 contacts the positioning seat 310. Specifically, a positioning tube is fixedly installed on one side wall of the positioning seat 310, and one end of the assembly pipe 510 is sleeved on the positioning tube. A sealing groove is provided on the other side wall of the positioning seat 310, and a sealing ring is installed in the sealing groove. The sealing ring contacts the outlet end of the pressure relief valve. A connecting screw 580 is fixedly installed on one side wall of the assembly pipe 510, and a nut 410 is fixedly installed on one side wall of the exhaust hood 40. The connecting screw 580 and the nut 410 are threadedly connected, and the connecting screw 580 and the nut 410 are compatible. The screw 580 is connected to the nut 410, which allows the assembly pipe 510 to be installed on one side wall of the exhaust hood 40. It should be noted that an external thread is provided on the outer wall of the filter pipe 30, while an internal thread is provided on the inner wall of the exhaust hood 40. The external thread and the internal thread are matched to facilitate the installation of the exhaust hood 40 on the filter pipe 30. Furthermore, the exhaust hood 40 is threaded onto the filter pipe 30. The exhaust hood 40 has several exhaust ports 420. Dustproof nets 430 are installed on the inner walls of the exhaust ports 420. The filtered gas is discharged to the outside through the exhaust ports 420, thereby relieving the internal pressure of the storage tank body 10 and purifying and discharging the ammonia gas. The dustproof nets 430 are used to filter external dust.

[0024] When this hazardous materials storage tank is in use: when the internal pressure of the storage tank body 10 increases, the excess gas inside is discharged through the pressure relief component 20. The gas enters the assembly pipe 510 through the pressure relief component 20, and then passes through several activated carbon filter blocks 530. After being adsorbed and filtered by several activated carbon filter blocks 530, the purified gas is discharged into the filter pipe 30 through the gas outlet 540 on the assembly pipe 510, and then discharged to the outside through the exhaust port 420, so as to achieve the pressure reduction inside the storage tank body 10 and the purification of the exhaust gas. When the activated carbon filter block 530 needs to be replaced, remove the exhaust hood 40 from the filter pipe 30, then remove the locking nut 610 from the locking screw 60, and the activated carbon filter block 530 can be removed from the positioning rod 520 to replace the new activated carbon filter block 530. Then, fix the activated carbon filter block 530 with the locking nut 610, and finally install the assembly tube 510 into the filter pipe 30.

[0025] It should be noted that the specific model and specifications of the storage tank body 10 and the pressure relief assembly 20 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0026] The power supply and principle of the storage tank body 10 and the pressure relief assembly 20 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
