Abstract
Description
Technical Field
[0001] The present application relates to the technical field of peroxide storage, and specifically relates to an emergency cooling device for peroxide storage. Background Art
[0002] Organic peroxides refer to organic compounds containing the -O-O- peroxy functional group formed by replacing the hydrogen atoms in hydrogen peroxide with organic groups such as alkyl groups, acyl groups, and aryl groups. Organic peroxides are mainly used as polymerization initiators and catalysts for synthetic resins. In the field of polymer materials, it can be used as an initiator for free radical polymerization, an initiator for grafting reactions, a cross-linking agent for rubber and plastics, a curing agent for unsaturated polyesters, and a regulator for molecular weight and molecular weight distribution in the preparation of spunbond polypropylene. It has the characteristics of decomposing to produce oxygen-containing free radicals when heated above a certain temperature, being unstable and easy to decompose.
[0003] Currently, it is mainly ensured safe storage by controlling its storage temperature. Once the temperature exceeds the predetermined temperature, only a large amount of water can be used for cooling. However, when cooling with water, the cooling speed is slow, and there is a risk of temperature runaway, resulting in the decomposition and explosion of peroxides, presenting a major safety hazard. Utility Model Content
[0004] In view of the deficiencies of the prior art, the present application provides an emergency cooling device for peroxide storage, which has the advantage of quickly reducing the temperature of peroxides and solves the problem that peroxides are prone to decomposition at too high temperatures.
[0005] To achieve the above object, the present application provides the following technical solution: An emergency cooling device for peroxide storage, including a storage bin, a storage tank body, a liquid nitrogen storage tank, an automatic valve I, a delivery pump, an automatic valve II, and a spray head. A plurality of groups of the storage tank bodies are installed on the inner bottom wall of the storage bin. The liquid nitrogen storage tank is connected in sequence through pipelines to the automatic valve I, the delivery pump, the automatic valve II, and the spray head. The delivery pump is located between the automatic valve I and the automatic valve II. The spray head is located at the position corresponding to the storage tank body at the top of the storage bin. A thermometer is installed on one side of the storage bin.
[0006] By automatically spraying liquid nitrogen, a large amount of heat is absorbed when the liquid nitrogen vaporizes, which can rapidly reduce the temperature of the stored organic peroxides, ensuring that the peroxides will not decompose and explode. At the same time, the oxygen in the storage space is also displaced, reducing the risk of peroxide combustion.
[0007] Preferably, an oxygen sensor and an automatic valve III are installed on the top of the storage bin.
[0008] The oxygen sensor detects the oxygen concentration inside the storage bin.
[0009] Preferably, an automatic valve IV is installed on one side of the storage bin.
[0010] External air can be introduced into the internal four-way storage bin through an automatic valve.
[0011] Preferably, an automatic valve is installed at the liquid inlet of the liquid nitrogen storage tank.
[0012] After the automatic valve on the liquid inlet of the liquid nitrogen storage tank is opened, liquid nitrogen is introduced into the internal of the liquid nitrogen storage tank for storage.
[0013] In summary, the beneficial effects of this application are as follows:
[0014] For this peroxide storage emergency cooling device, through automatic control, when the temperature of the organic peroxide storage exceeds the limit, liquid nitrogen is automatically sprayed in. When the liquid nitrogen vaporizes, it absorbs a large amount of heat, which can rapidly reduce the temperature of the stored organic peroxide, ensuring that the peroxide will not decompose and explode. At the same time, it also displaces the oxygen in the storage space, reducing the risk of peroxide combustion. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.
[0018] Please refer to Figure 1, A peroxide storage emergency cooling device, comprising a storage bin 1, a storage tank body 2, a liquid nitrogen storage tank 4, a first automatic valve 5, a delivery pump 6, a second automatic valve 7 and a spray head 8. A number of groups of storage tank bodies 2 are installed on the inner bottom wall of the storage bin 1, and peroxides are stored inside the storage tank bodies 2. The liquid nitrogen storage tank 4 is connected in sequence through pipelines to the first automatic valve 5, the delivery pump 6, the second automatic valve 7 and the spray head 8. An automatic valve is installed at the liquid inlet of the liquid nitrogen storage tank 4. When the automatic valve at the top of the liquid nitrogen storage tank 4 is opened, liquid nitrogen enters and is stored inside the liquid nitrogen storage tank 4. The delivery pump 6 is located between the first automatic valve 5 and the second automatic valve 7. After the delivery pump 6 is started, the delivery pump 6 extracts the liquid nitrogen inside the liquid nitrogen storage tank 4 through a pipeline. The spray head 8 is located at a position corresponding to the storage tank body 2 at the top of the storage bin 1. A thermometer 3 is installed on one side of the storage bin 1, and the thermometer 3 can detect the temperature inside the storage bin 1 at all times. An oxygen sensor 9 and a third automatic valve 10 are installed at the top of the storage bin 1. The oxygen sensor 9 can detect the oxygen concentration inside the storage bin 1. A fourth automatic valve 11 is installed on one side of the storage bin 1.
[0019] Working principle: When the probe of the thermometer 3 detects that the temperature inside the storage bin 1 is higher than the set temperature and reaches the temperature at which its stored products accelerate self-decomposition, when the temperature inside the storage bin 1 exceeds the adjustment range of the storage bin 1, the PLC controls the third automatic valve 10 to open, and the first automatic valve 5 and the delivery pump 6 to open. When the delivery pump 6 is started, the delivery pump 6 extracts the liquid nitrogen inside the liquid nitrogen storage tank 4 and transports it to the spray head 8 through a pipeline. The spray head 8 sprays the liquid nitrogen into the storage bin 1. After the liquid nitrogen vaporizes and absorbs heat, it is discharged through the third automatic valve 10, thereby reducing the temperature of the storage tank body 2 inside the storage bin 1. When the probe of the thermometer 3 detects that the temperature inside the storage bin 1 reaches the storage temperature, the delivery pump 6 stops, the first automatic valve 5 and the delivery pump 6 are closed, and the fourth automatic valve 11 is opened to start air replacement. When the oxygen sensor 9 detects that the oxygen concentration inside the storage bin 1 reaches more than 21%, the third automatic valve 10 and the fourth automatic valve 11 are closed, and the storage space returns to a safe state.
