Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen peroxide storage, in particular to a spray cooling device for a hydrogen peroxide storage tank. Background Art

[0002] Hydrogen peroxide, also known as hydrogen peroxide, has the chemical formula H2O2 and is commonly known as hydrogen peroxide. It appears as a colorless, transparent liquid and is a strong oxidant listed in the "List of Dangerous Chemicals that May Cause Explosions." Yimen Copper Co., Ltd. uses a 27.5% concentration of hydrogen peroxide, primarily for use in the desulfurization of acid production exhaust and flue gas desulfurization. Hydrogen peroxide is highly oxidizing and unstable, requiring strict temperature control during storage to avoid excessive temperatures that could cause it to decompose and release oxygen, potentially leading to explosions and other safety hazards. According to the "Mandatory Regulations for the Safety Management of Major Hazard Sources of Yunnan Copper Co., Ltd.", hydrogen peroxide should be stored in a cool, well-ventilated warehouse. Keep away from sources of fire and heat. The storage temperature should not exceed 30°C. Keep the container sealed. Store it separately from flammable and combustible materials, reducing agents, and reactive metal powders, and avoid mixing with them.

[0003] Currently, the most common method for cooling hydrogen peroxide storage tanks is through manually operated spraying devices. However, this method suffers from issues such as delayed operation and unstable cooling effects. Furthermore, some existing automatic spraying devices suffer from low accuracy and reliability in temperature monitoring and control, failing to meet the safety requirements for hydrogen peroxide storage. To accommodate inspection ladders, hydrogen peroxide storage tanks have flanges on the top, preventing existing spraying devices from reaching the upper portion of the tank, resulting in locally high hydrogen peroxide temperatures that do not meet storage requirements.

[0004] The utility model patent with the authorization announcement number CN217457227U discloses an automatic spray cooling system for hydrogen peroxide storage tanks, including a remote temperature measuring device, a control system and a spray device. The remote temperature measuring device is installed on the finished product storage tank to measure the temperature inside the finished product storage tank; the control system is used to receive and process the measurement data fed back by the remote temperature measuring device; the control system is provided with a remote control terminal; the spray device includes an automatic spray valve and a spray coil arranged on the outer wall of the finished product storage tank, the automatic spray valve is installed between the spray coil and the external water main, and the automatic spray valve is electrically connected to the control system; the control system includes a microprocessor, a memory Storage module and comparator, the above-mentioned finished product storage tank is made of stainless steel, and the spray coil is arranged on the upper periphery of the finished product storage tank, and a number of nozzles are arranged on the spray coil, wherein the nozzle sprays toward the middle of the finished product storage tank, and the water gathered in the middle of the finished product storage tank will automatically leak out from its peripheral side due to gravity, so that uniform cooling can be achieved. In this patent, the finished product storage tank is sprayed and cooled by the nozzle, but the water flow sprayed by the nozzle is located in the middle of the finished product storage tank. If there is a flange on the upper part of the storage tank, when the water flow leaks along the periphery, it is blocked by the flange, and the water flow is difficult to flow down along the upper outer wall of the storage tank, resulting in insufficient spraying in some areas of the storage tank, and the temperature of the local hydrogen peroxide is high, which does not meet the storage requirements.
