Description

A novel ammonia leak detection and pressurization device Technical Field

[0001] This utility model relates to the technical field of ammonia leak detection, specifically a novel ammonia leak detection pressurization device. Background Technology

[0002] In the production of ammonia, the combination reaction of nitrogen and hydrogen is a reversible reaction, meaning that the reaction cannot proceed to completion. There exists a fixed ratio that allows the reaction to reach a steady state, where the amount of ammonia no longer increases. Adding carbon dioxide as a catalyst can reduce the pressure required for the reaction, and increasing pressure can promote the reaction towards the production of ammonia. Specifically, increasing pressure can increase the frequency of collisions between reactant molecules, thereby increasing the reaction rate and yield.

[0003] For example, the authorization announcement number "CN110316744B" is titled "A Device for Preparing Ammonia." The optimized design of the ammonia generator structure improves the ammonia conversion rate of urea. The arrangement of the turbulence surface can enhance the intensity of the generated turbulence and eddies. Currently, ammonia needs to be stored in containers after preparation. However, containers may have tiny holes that cause ammonia leakage. Leaked ammonia can easily cause pollution and danger. Therefore, it is necessary to perform leak detection on the containers containing ammonia. The conventional leak detection method relies on the principle that pH reagent changes color when it comes into contact with ammonia. When the holes on the surface of the ammonia container are small, the amount of ammonia leaking outward from the inside will be negligible, so it is not easy to be detected by pH reagent, which greatly affects the efficiency of ammonia leak detection. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in existing ammonia leak detection equipment, because the amount of ammonia leaking outward from the inside is negligible when the pores on the surface of the ammonia container are small, making it difficult to be detected by pH reagents and greatly affecting the efficiency of ammonia leak detection. Therefore, a new type of ammonia leak detection pressurization device is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel ammonia leak detection and pressurization device is designed, comprising a leak detection box, thickened blocks, and side plates. The side plates are fixedly connected to one side of the outer wall of the leak detection box, and the two thickened blocks are fixedly installed at the upper and lower ends of the leak detection box. An ammonia leak detection and pressurization structure is provided above the side plates. The leak detection box is equipped with a leak safety collection and treatment structure inside, and a sealing structure is provided on the outer wall of the leak detection box.

[0007] This feature involves horizontally welding a side panel to one side of the leak detection box's outer wall. The top of the side panel is used to house the pressure pump. Two thickened blocks are fixedly installed at the top and bottom ends of the leak detection box. These thickened blocks are made of stainless steel metal blocks welded to the top and bottom ends of the leak detection box. The thickened blocks improve the overall stability and sturdiness of the leak detection box.

[0008] Preferably, the ammonia leak detection pressurization structure includes a pressurization pump and a connecting pipe. The pressurization pump is fixedly connected to the top of the side plate, and a gas supply pipe is fixedly connected to the top of the pressurization pump. A connecting pipe is fixedly connected above the gas supply pipe, and an air inlet is fixedly connected to the lower end of the pressurization pump. A control valve is fixedly installed on the outside of the connecting pipe, and a mating sleeve is threaded to the other end of the connecting pipe.

[0009] This setup features two pipes connected to the top and bottom of the pressurizing pump. The top gas delivery pipe, connected to a connecting pipe via a sealed flange, is used to inject pressurized ammonia gas into the ammonia container. The bottom gas inlet of the pressurizing pump is used to connect to the ammonia storage cylinder that needs pressurization. The control valve can be manually turned on and off, facilitating the control of the pressurized ammonia gas being injected into the ammonia container on the other side through the connecting pipe. The other end of the connecting pipe is threaded with a connecting sleeve, which allows operators to rotate and tighten the ammonia container that needs to be leak-tested onto the lower end of the connecting pipe, enabling the replacement of different ammonia container cylinders for testing.

[0010] Preferably, an ammonia container is movably placed inside the leak detection box, and pH test paper is movably wrapped around the outer wall of the ammonia container.

[0011] This feature includes a pH test strip that is evenly wrapped around the outer wall of the ammonia container. When a leak or leak point is found in the ammonia container, the pressurized ammonia gas will come into contact with the pH test strip. The color change of the pH test strip indicates whether there is a leak in the container.

[0012] Preferably, the top of the ammonia container is fixedly connected to the docking sleeve.

[0013] Preferably, the leak safety collection and treatment structure includes an exhaust screen and a sealing head. The exhaust screen is fixedly connected to one side of the inner wall of the leak detection box, and a suction pump is fixedly connected to the other end of the exhaust screen. An exhaust pipe is fixedly connected to the other side of the suction pump, and the sealing head is fixedly connected to the other end of the exhaust pipe.

[0014] This exhaust screen is used to vent residual ammonia gas after the leak detection chamber has been tested. The sealing head is inserted into the glass bottle needed to handle the residual ammonia gas, and then the power is connected to start the vacuum pump. The vacuum pump sucks out the leaking ammonia gas from inside the leak detection chamber along the exhaust pipe and exhaust screen. This reduces the possibility of personnel directly contacting the leaking ammonia gas after the outer sealing door is opened, thus improving the safety of use.

[0015] Preferably, the sealing structure includes a sealing door and locking bolts. The sealing door is rotatably connected to the front end of the outer wall of the leak detection box via a hinge. A leak-proof ring is fixedly connected to the inner wall of the sealing door. Two locking bolts are threadedly connected to the inner side of the sealing door, and the ends of the two locking bolts are threadedly connected to the inner wall of the leak detection box.

[0016] The sealing door is made of stainless steel that fits the outer wall of the leak detection box. The leak-proof ring is made of rubber material embedded around the inside of the sealing door. After the sealing door is closed, the leak-proof ring can fit tightly around the outer wall of the leak detection box, improving the sealing performance and reducing ammonia leakage. The locking bolt is screwed horizontally between the sealing door and the leak detection box to reinforce and lock the sealing door.

[0017] This utility model proposes a novel ammonia leak detection and pressurization device, which has the following advantages: the gas delivery pipe is connected to a connecting pipe with a sealing flange to inject pressurized ammonia gas into the ammonia container cylinder, while the air inlet below the pressurization pump is used to connect to the ammonia storage cylinder that needs to be pressurized and transported. The control valve can be manually turned to open and close, making it convenient to control the pressurized ammonia gas to be injected into the ammonia container cylinder on the other side through the connecting pipe. The docking sleeve allows the operator to rotate and tighten the ammonia container cylinder to be leaked to the lower end of the connecting pipe. By pressurizing the ammonia container to be tested, the increased pressure can squeeze out the internal ammonia gas through small holes, which can improve the accuracy of leak detection and is also suitable for small holes, thus improving work efficiency.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] Example:

[0027] Please refer to Figures 1-6. In this embodiment, a novel ammonia leak detection and pressurization device includes a leak detection box 1, thickened blocks 2, and side plates 3. The side plates 3 are fixedly connected to one side of the outer wall of the leak detection box 1 and are horizontally welded to one side of the outer wall of the leak detection box 1. The side plates 3 are used to house a pressurization pump 41. Two thickened blocks 2 are fixedly installed at the upper and lower ends of the leak detection box 1. The thickened blocks 2 are made of stainless steel metal blocks welded to the upper and lower ends of the leak detection box 1. The thickened blocks 2 can improve the overall firmness and sturdiness of the leak detection box 1. An ammonia leak detection and pressurization structure 4 is provided above the side plates 3. A leak safety collection and treatment structure 6 is provided inside the leak detection box 1. A sealing structure 7 is provided on the outer wall of the leak detection box 1.

[0028] The ammonia leak detection pressurization structure 4 includes a pressurization pump 41 and a connecting pipe 44. The pressurization pump 41 is fixedly connected to the top of the side plate 3. Two pipes are connected to the top and bottom of the pressurization pump 41. The top gas supply pipe 52 is connected to the connecting pipe 44 with a sealing flange to inject pressurized ammonia into the ammonia container cylinder 51. The top of the pressurization pump 41 is fixedly connected to the gas supply pipe 42, and the connecting pipe 44 is fixedly connected above the gas supply pipe 42. The bottom end of the pressurization pump 41 is fixedly connected to the air inlet 46. It is used to connect to the ammonia storage cylinder that needs to be pressurized and transported. A control valve 43 is fixedly installed on the outside of the connecting pipe 44. The control valve 43 can be manually turned to open and close, so as to control the pressurized ammonia gas to be injected into the ammonia container cylinder 51 on the other side through the connecting pipe 44. The other end of the connecting pipe 44 is threadedly connected to the docking sleeve 45. The docking sleeve 45 makes it easy for the staff to rotate and tighten the ammonia container cylinder 51 that needs to be leak-tested to the lower end of the connecting pipe 44, so as to replace the ammonia container cylinder 51 to be tested.

[0029] An ammonia container bottle 51 is movably placed inside the leak detection box 1. A pH test paper 52 is movably wrapped around the outer wall of the ammonia container bottle 51. When the ammonia container to be tested has a leak or leak point, the ammonia gas squeezed out under pressure will come into contact with the pH test paper wrapped on the outside. The color change of the pH test paper indicates whether there is a leak in the container. The top of the ammonia container bottle 51 is fixedly connected to the docking sleeve 45.

[0030] The leak safety collection and treatment structure 6 includes an exhaust net 61 and a sealing head 64. The exhaust net 61 is fixedly connected to one side of the inner wall of the leak detection box 1. The exhaust net 61 is used to exhaust the residual ammonia gas after the leak detection box 1 has been tested. The other end of the exhaust net 61 is fixedly connected to a vacuum pump 62. The other side of the vacuum pump 62 is fixedly connected to an exhaust pipe 63. The sealing head 64 is fixedly connected to the other end of the exhaust pipe 63. The sealing head 64 is inserted into the glass bottle needed to treat the residual ammonia gas. Then, the power is connected and the vacuum pump 62 is started. The vacuum pump 62 sucks out the leaked ammonia gas inside the leak detection box 1 along the exhaust pipe 63 and the exhaust net 61. This can reduce the situation where the staff directly comes into contact with the leaked ammonia gas after the outer sealing door 71 is opened, thus improving the safety of use.

[0031] The sealing structure 7 includes a sealing door 71 and locking bolts 73. The sealing door 71 is hinged to the front end of the outer wall of the leak detection box 1. The sealing door 71 is made of stainless steel that fits the outer wall of the leak detection box 1. A leak-proof ring 72 is fixedly connected to the inner wall of the sealing door 71. The leak-proof ring 72 is made of rubber material embedded around the inside of the sealing door 71. After the sealing door 71 is closed, the leak-proof ring 72 can fit tightly around the outer wall of the leak detection box 1 to improve the sealing performance and reduce ammonia leakage. Two locking bolts 73 are threaded to the inside of the sealing door 71. The locking bolts 73 are screwed horizontally between the sealing door 71 and the leak detection box 1 to reinforce and lock the sealing door 71. The ends of the two locking bolts 73 are threaded to the inner wall of the leak detection box 1.

[0032] Working principle:

[0033] The new type of ammonia leak detection pressurization equipment causes ammonia to leak through tiny holes on the surface of the container bottle by pressurizing it. It allows pH test paper to come into contact with ammonia. When the pH test paper shows partial color change, it can be determined that the container has leaked and the specific location of the leak can be determined.

[0034] Side plate 3 is horizontally welded to one side of the outer wall of leak detection box 1. The upper part of side plate 3 is used to place pressure pump 41. Two thickened blocks 2 are fixedly installed at the upper and lower ends of leak detection box 1. The thickened blocks 2 are made of stainless steel metal blocks welded to the upper and lower ends of leak detection box 1. The thickened blocks 2 can improve the overall firmness and sturdiness of leak detection box 1.

[0035] The outer wall of the ammonia container 51 is movably wrapped with pH test paper 52. The pH test paper is evenly wrapped around the outer wall of the ammonia container 51. When the ammonia container to be tested has a leak or leak point, the ammonia gas squeezed out under pressure will come into contact with the pH test paper wrapped on the outside. The color change of the pH test paper can be used to determine whether there is a leak in the container.

[0036] The pressurizing pump 41 has two pipes connected at the top and bottom. The top gas delivery pipe 52 is connected to the connecting pipe 44 by a sealing flange to inject pressurized ammonia gas into the ammonia container cylinder 51. The air inlet 46 at the bottom of the pressurizing pump 41 is used to connect to the ammonia storage cylinder that needs to be pressurized and transported. The control valve 43 can be manually turned to open and close, so as to control the pressurized ammonia gas to be injected into the ammonia container cylinder 51 on the other side through the connecting pipe 44. The other end of the connecting pipe 44 is threaded with a docking sleeve 45. The docking sleeve 45 makes it easy for the staff to rotate and tighten the ammonia container cylinder 51 that needs to be leak-tested to the lower end of the connecting pipe 44, and can replace different ammonia container cylinders 51 to be tested.

[0037] The exhaust net 61 is used to exhaust the residual ammonia gas inside the leak detection box 1 after the leak detection is completed. The sealing head 64 is inserted into the glass bottle needed to handle the residual ammonia gas. Then, the power supply is connected and the vacuum pump 62 is started. The vacuum pump 62 sucks out the leaked ammonia gas inside the leak detection box 1 along the exhaust pipe 63 and the exhaust net 61. This can reduce the situation where the staff directly come into contact with the leaked ammonia gas after the outer sealing door 71 is opened, thus improving the safety of use.

[0038] The sealing door 71 is made of stainless steel that fits the outer wall of the leak detection box 1. The leak-proof ring 72 is made of rubber material embedded around the inside of the sealing door 71. After the sealing door 71 is closed, the leak-proof ring 72 can fit tightly around the outer wall of the leak detection box 1 to improve the sealing performance and reduce ammonia leakage. The locking bolt 73 is screwed horizontally between the sealing door 71 and the leak detection box 1 to reinforce and lock the sealing door 71.
