[0002] A liquid chlorine cylinder is a high-pressure container used for storing and transporting liquid chlorine. Liquid chlorine is an important chemical raw material and is widely used in fields such as water treatment, bleaching, and disinfection. Liquid chlorine cylinders are usually made of high-strength steel and can withstand high pressure and corrosion.

[0003] Due to the serious problems caused by chlorine leakage, the quality, sealing performance, and stability of liquid chlorine cylinders are particularly important. If abnormal situations occur, they need to be dealt with in a timely manner.

[0004] The original disposal of abnormal situations of liquid chlorine cylinders was to use an alkali pool to absorb the liquid chlorine in the cylinder. In this case, the liquid chlorine cylinder would be placed in the alkali pool, and any leaked chlorine would be absorbed by the alkali solution in the alkali pool immediately.

[0005] However, during use, the liquid chlorine cylinder would be scrapped, chlorine would be wasted, and sodium hydroxide solution would also be wasted. Moreover, the alkali in the alkali pool needed to be replaced regularly, which became a fixed expense, increasing the cost and bringing inconvenience to users. Content of the Utility Model

Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0038] In the embodiments of the present application, please refer to Figure 1 , an abnormal negative pressure disposal box for a liquid chlorine cylinder, including an outer shell 10. A treatment chamber 20 is arranged inside the outer shell 10. A reinforcing plate 12 is fixed on the inner wall of the outer shell 10 to increase the overall strength. A bottom plate 30 is fixed inside the outer shell 10. An intake pipe 40 communicating with the bottom end of the treatment chamber 20 is arranged on the side of the outer shell 10. The communicating position of the intake pipe 40 is below the bottom plate 30. An exhaust structure 50 is arranged on the side of the outer shell 10. The exhaust structure 50 communicates with the treatment chamber 20 to generate negative pressure and is externally connected to a decontamination tower. The decontamination tower can be an existing waste gas treatment tower. In factories such as chlorine gas factories, waste gas treatment towers need to be installed as required to treat the waste gas generated during the processing. The exhaust structure 50 of the present application can be externally connected to an existing decontamination tower in an existing manner. A feed hole is opened on the side of the outer shell 10, and a sealing door 11 is arranged at the feed hole. The sealing door 11 can adopt an existing sealing door structure;

[0039] During use, when the liquid chlorine cylinder leaks abnormally, the liquid chlorine cylinder is placed in the treatment chamber 20, then the sealing door 11 is closed, and then negative pressure is generated through the exhaust structure 50. The chlorine gas leaked from the liquid chlorine cylinder can be sucked into the exhaust structure 50 and then transmitted to the decontamination tower for treatment. The operation is simple, there is no need to additionally set up an alkali pool, the cost is reduced, and the liquid chlorine cylinder can be taken out and repaired to the qualified range and then used continuously, reducing waste consumption and not being scrapped because it is thrown into the alkali pool.

[0040] In a further embodiment, the exhaust structure 50 includes a fixed sleeve 51 fixed to the side of the outer shell 10 and communicating with the processing chamber 20. The fixed sleeve 51 is fixedly connected to a fixed pipe 52 with a through hole formed inside and communicating with the fixed sleeve 51. At the top of the fixed pipe 52, an air outlet pipe 53 and an external connection pipe 54 communicating with the through hole are fixed. The external connection pipe 54 is externally connected to a decontamination tower. A negative pressure fan 55 is arranged inside the fixed sleeve 51, and a chlorine gas sensor 56 is arranged inside the fixed pipe 52. The chlorine gas sensor 56 can adopt an existing chlorine gas detection sensor and is electrically connected to an existing controller, such as a PLC controller, and is connected, controlled, operated, and signals are transmitted in an existing manner. Electromagnetic valves are arranged at the inlet pipe 40, the air outlet pipe 53, and the external connection pipe 54. The electromagnetic valves are connected and controlled in an existing manner and are electrically connected to the controller;

[0041] During use, open the electromagnetic valve at the inlet pipe 40 so that external air can enter the processing chamber 20 for the user's needs. For example, at the end of chlorine gas treatment, the electromagnetic valve at the inlet pipe 40 can be opened to allow air to enter and gradually replace the chlorine gas inside the processing chamber 20, so as to open the sealing door 11 subsequently. During the treatment process, start the negative pressure fan 55 to generate negative pressure, suck the leaked chlorine gas into the fixed pipe 52, and then open the electromagnetic valve at the external connection pipe 54 to send the chlorine gas to the decontamination tower through the external connection pipe 54. When the chlorine gas sensor 56 detects no chlorine gas, the electromagnetic valves at the air outlet pipe 53 and the inlet pipe 40 can also be opened to conduct air circulation inside the processing chamber 20. Usually, the electromagnetic valve at the air outlet pipe 53 is in a closed state.

[0042] The above-mentioned negative pressure fan 55 can also be replaced with an air pump according to needs. The air inlet end of the air pump communicates with the processing chamber 20, and the air outlet end of the air pump communicates with the fixed pipe 52.

[0043] In a further embodiment, please refer to Figure 1 and 2 , a chlorine gas storage tank 70 is arranged on the side of the outer shell 10. The chlorine gas storage tank 70 communicates with the through hole inside the fixed pipe 52 through a gas delivery frame 80. A fixed frame 60 is fixed on the side of the outer shell 10. Among them, the gas delivery frame 80 includes a gas delivery pump 81 fixedly connected to the fixed frame 60. One end of a connecting pipe 82 is connected to the air inlet end of the gas delivery pump 81, and the other end of the connecting pipe 82 is connected to the fixed pipe 52. An electromagnetic valve is arranged at the connecting pipe 82. A gas tank valve 84 is arranged at the top of the chlorine gas storage tank 70. One end of a gas delivery pipe 83 is connected to the air outlet end of the gas delivery pump 81, and the other end of the gas delivery pipe 83 is connected to the gas tank valve 84. The gas delivery pump 81 is an existing air pump and is connected and controlled in an existing manner. The gas tank valve 84 is a common existing gas tank valve, and its connection method with the gas delivery pipe 83 also adopts an existing one. Specifically, the valve of a gas cylinder and its connection method during gas filling can be referred to;

[0044] During the above process of handling liquid chlorine cylinders, when the chlorine gas sensor 56 senses that the chlorine gas concentration meets the requirements for recycling and reuse, the solenoid valves at the gas outlet pipe 53 and the external connection pipe 54 can be closed, and the solenoid valve at the connection pipe 82 can be opened to send it to the recycling equipment for recycling and reuse. For example, the air supply pump 81 can be started to increase the air pressure, and the chlorine gas can be sent into the chlorine gas storage tank 70 for recycling after passing through the connection pipe 82, the air supply pump 81, the air supply pipe 83, and the gas tank valve 84 in sequence. After the recycling is completed, just tighten the gas tank valve 84. The operation is simple and convenient for recycling.
