Description

Technical Field

[0001] This utility model relates to the field of waste gas adsorption technology, specifically a waste gas adsorption device for storage tanks. Background Technology

[0002] Energy storage plays a crucial role in ensuring the safe operation of electricity. Energy storage systems, especially flow battery systems, use electrolytes that are classified as sulfate-based, hydrochloric acid-based, or a mixture of both. During charging and discharging, these electrolytes often produce volatile acidic waste gases. Hydrochloric acid-based electrolytes may even produce toxic gases such as chlorine. Routine treatment of these waste gases typically involves mixing or using multi-stage alkaline absorption tanks, but these methods are time-consuming, labor-intensive, prone to clogging pipelines, and cannot completely neutralize the acids and water vapors in the waste gases. This can lead to severe environmental pollution and even endanger personal safety.

[0003] A search (application number: 202222819611.1) reveals a flow battery storage tank exhaust gas adsorption and purification device, comprising: a separable splicing cylinder, a splicing front end, a splicing rear end, a mesh, and filter material; the splicing front end is connected to the separable splicing cylinder; the separable splicing cylinder is connected to the splicing rear end; and the separable splicing cylinder is equipped with a mesh and filter material.

[0004] In the process of realizing this utility model, the inventors discovered the following problems in the prior art that have not been solved: Although the device has a good splicing function, its multiple filter cylinder mechanisms are screwed together. Whenever the adsorption material and filter screen are cleaned or replaced regularly, they need to be disassembled and screwed together one by one, which is time-consuming and laborious and urgently needs to be improved. Therefore, we propose a storage tank exhaust gas adsorption device. Utility Model Content

[0005] The purpose of this invention is to provide a storage tank exhaust gas adsorption device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a storage tank exhaust gas adsorption device, comprising filter cylinders, wherein there are four sets of filter cylinders, and a flange is fixedly installed at one end of three sets of filter cylinders;

[0007] A recessed platform is provided on one side of the flange, and the recessed platform is annular. An opening is provided on the side of the flange near the recessed platform, and a filter screen is fixedly installed in the opening. Sleeves are fixedly installed on both sides of the flange and both sides of a set of filter cylinders.

[0008] The three sets of filter cartridges are positioned in the recessed platform on the same side. Limiting rods are placed on both sides of the filter cartridges. Sealing rings are fixedly installed on the side of the three sets of filter cartridges near the flange.

[0009] The limiting rod moves through the middle of the sleeve. A stop block is fixedly installed at one end of the limiting rod, and a screw block is screwed to the other end of the limiting rod through an external thread.

[0010] Both sets of flanges are fixedly mounted with limiting frames, and the limiting frames have grooves. Microswitches, batteries, and alarms are fixedly installed in the grooves. The batteries are electrically connected to the microswitches via wires, and the microswitches are electrically connected to the alarms via wires. They can be used in conjunction with components such as limiting rods, sleeves, and flanges. During the use of the adsorption device, the filter cartridges can be inserted into the recesses of the flanges, the limiting rods can pass through the sleeves, and the screw blocks can be turned to apply a squeezing force to the filter cartridges. With the help of the sealing rings, the cartridges can be connected and sealed. During this process, exhaust gas can be treated through the adsorption material and filter screen. Conversely, during periodic cleaning, the screw blocks can be turned and the limiting rods can be removed to separate the four sets of filter cartridges and clean or replace the adsorption material and filter screens. Compared with the existing threaded connection method, this method is more convenient for later cleaning and replacement.

[0011] As an optional solution to the technical solution of this application, the limiting frame has rod grooves on both sides, and a T-shaped rod is movably locked in the rod groove. A spring is sleeved on the outside of the T-shaped rod, and the two ends of the spring are connected to the T-shaped rod and the limiting frame respectively. It can be used in conjunction with components such as micro switches and T-shaped rods. During long-term use, if the screw block becomes loose due to vibration, the spring has a reaction force, and in the loose state, it can resist and drive the stop block to move, so that it no longer presses the active button of the micro switch. The battery powers the alarm, and the alarm sounds. This structure is used for the loosening reminder function to prevent leakage from being detected in time.

[0012] As an optional solution to the technical solution of this application, an indicator sign is fixedly installed on a set of the flanges, and the indicator sign is fixed by welding. The guide text on the indicator sign can inform the operator of the corresponding procedures, making it easier to understand the product and its use.

[0013] As an optional solution to the technical solution of this application, the outer ends of both sets of filter cylinders are connected to a connecting cylinder. The outer wall of the connecting cylinder is provided with a connecting thread, which can be used to detachably connect the external exhaust assembly and the storage tank assembly for the adsorption device.

[0014] As an optional solution to the technical solution of this application, the front wall of the limiting frame is provided with a sound outlet, and a dustproof net is fixedly installed inside the sound outlet. The alarm sound can be transmitted through the sound outlet, and the dustproof net can block external dust.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model discloses a tank exhaust gas adsorption device. By setting a limiting rod, a sleeve, and a flange, during the use of the adsorption device, the filter cartridge can be inserted into the recess of the flange, the limiting rod passes through the sleeve, and the screw block is turned to apply a squeezing force to the filter cartridge. With the help of the sealing ring, the cylinder can be connected and sealed. During this period, exhaust gas can be treated through the adsorption material and filter screen. Conversely, during periodic cleaning, the screw block is turned and the limiting rod is pulled out, so that the four sets of filter cartridges can be separated and the adsorption material and filter screen can be cleaned or replaced. Compared with the existing threaded connection method, it is easier to clean and replace in the later stage.

[0017] 2. This utility model discloses a storage tank exhaust gas adsorption device, which is equipped with a micro switch and a T-shaped rod. During long-term use, if the screw block becomes loose due to vibration, the spring has a reaction force, and the loosened block can be moved by resisting it, so that the micro switch button is no longer pressed. The battery powers the device, and the alarm sounds. This structure is used for the loosening reminder function to prevent leakage from being detected in time. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-3This utility model provides a technical solution: a tank exhaust gas adsorption device, including filter cylinders 1, of which there are four sets. Three sets of filter cylinders 1 have flanges 2 fixedly installed at one end, and two sets of filter cylinders 1 have connecting cylinders 11 connected to their outer ends. The outer wall of the connecting cylinders 11 has connecting threads, allowing for detachable connection between the external exhaust assembly and the tank assembly via these threads. A recessed platform 24, which is annular, is provided on one side of the flange 2. An opening 25 is provided on the side of the flange 2 near the recessed platform 24, and a filter screen 23 is fixedly installed inside the opening 25. Sleeves 22 are fixedly installed on both sides of the flange 2 and both sides of one set of filter cylinders 1. An indicator sign 21 is fixedly installed on one set of flanges 2, and the indicator sign 21 is fixed by welding. The guiding text on the indicator sign 21 informs the operator of the corresponding procedures. For easy understanding of the product and its use; three sets of filter cartridges 1 are positioned in the recess 24 on the same side, and limit rods 3 are placed on both sides of the filter cartridges 1. Sealing rings 12 are fixedly installed on the side of the three sets of filter cartridges 1 near the flange 2; the limit rods 3 move through the middle of the sleeve 22, and a stop block 31 is fixedly installed at one end of the limit rods 3, and a screw block 32 is screwed to the other end of the limit rods 3 through external threads; limit frames 4 are fixedly installed on the front side of the two sets of flanges 2, and grooves 43 are opened in the limit frames 4. A sound outlet is opened on the front wall of the limit frames 4, and a dustproof net is fixedly installed in the sound outlet. The alarm sound can be transmitted through the sound outlet, and the dustproof net can block external dust. A micro switch 42, a battery 44 and an alarm 45 are fixedly installed in the groove 43. The battery 44 is electrically connected to the micro switch 42 through wires, and the micro switch 42 is electrically connected to the alarm 45 through wires.

[0025] In this technical solution, components such as the limiting rod 3, sleeve 22, and flange 2 can be used together. During the use of the adsorption device, the filter cylinder 1 can be inserted into the recess 24 of the flange 2, allowing the limiting rod 3 to pass through the sleeve 22. By turning the screw block 32, a squeezing force can be applied to the filter cylinder 1. With the help of the sealing ring 12, the cylinder can be connected and sealed. During this period, the exhaust gas can be treated through the adsorption material and filter screen 23. Conversely, during periodic cleaning, the screw block 32 can be turned and the limiting rod 3 can be removed to separate the four sets of filter cylinders 1 and clean or replace the adsorption material and filter screen. Compared with the existing threaded connection method, it is easier to clean and replace in the later stage.

[0026] In some technical solutions, the limiting frame 4 has rod grooves 41 on both sides, and a T-shaped rod 5 is movably locked in the rod groove 41. A spring 51 is sleeved on the outside of the T-shaped rod 5, and the two ends of the spring 51 are connected to the T-shaped rod 5 and the limiting frame 4 respectively.

[0027] In this technical solution, components such as micro switch 42 and T-bar 5 can be used together. During long-term use, if the screw block 32 becomes loose due to vibration, the spring 51 has a reaction force. In the loose state, it can resist and drive the stop block 31 to move, so that it no longer presses the active button of micro switch 42. The battery 44 supplies power and the alarm 45 sounds an alarm. This structure is used for the loosening reminder function to prevent leakage from being detected in time.

[0028] Working principle: It should be noted that this utility model is a storage tank exhaust gas adsorption device. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0029] When a waste gas adsorption device for a storage tank is used, the waste gas adsorption device is transported to one side of the storage tank, and the adsorption material is filled into one side of the filter screen 23 of the filter cylinder 1. After the device is assembled, the adsorption pipes are connected to the external exhaust device and the storage tank through the connecting cylinders 11 on both sides. During this period, the waste gas can be adsorbed and filtered by the adsorption device for waste gas adsorption treatment.

[0030] By setting up a limiting rod 3, a sleeve 22, and a flange 2, during the use of the adsorption device, the filter cartridge 1 can be inserted into the recess 24 of the flange 2, allowing the limiting rod 3 to pass through the sleeve 22. Tightening the screw block 32 can apply a squeezing force to the filter cartridge 1, and with the cooperation of the sealing ring 12, the cartridges can be connected and sealed. During this process, the adsorption material and filter screen 23 can be used to treat waste gas. Conversely, during periodic cleaning, the screw block 32 can be turned and the limiting rod 3 can be removed to separate the four sets of filter cartridges 1 for cleaning or replacement. Compared to existing threaded connections, the adsorption material and filter screen are easier to clean and replace later. With the micro switch 42 and T-shaped rod 5, if the screw block 32 becomes loose due to vibration during long-term use, the spring 51 has a reaction force, which can resist and drive the stop block 31 to move in the loose state, so that it will no longer press the active button of the micro switch 42. The battery 44 provides power and the alarm 45 sounds an alarm. This structure is used for the loosening reminder function to prevent leakage from being detected in time.
